description: Technologies merging enhanced oil recovery with In-situ upgrading can significantly increase the economic and environmentally efficiency of unconventional oil exploitation. The development of Nanocatalytic In-situ Upgrading via Dense Hot Fluid Injection is a promising approach that takes advantage of upgrading lowest value bitumen fractions while promoting additional recovery of oil in place. This research addresses some important aspects related to the development of this novel technology, focusing on the until now unattended relevance of thermal kinetics (absence of catalyst particles), the precise range of particles sizes produced using the nano-catalyst manufacturing unit prototype built by the research group and the interaction rock-nano-particles relevant for the targeted catalyst deposition. The main limitation facing in-situ thermal upgrading (in porous media) of Athabasca bitumen was found to be product stability. Vacuum residue conversions above 32% result in unstable products, and although high viscosity reductions and moderate improvement of other properties are obtained they are not sufficient to produce transportable products. Additionally coke precursors are significantly retained by the porous media that further limiting the process. The kinetic modeling of thermal upgrading in porous media demonstrated the catalytic behavior of the sand pack reflected in an increase of the apparent reaction order for the vacuum residue to a second-order-of reaction. The use of Nanoparticle Tracking Analysis (NTA) for size determination of nano-catalyst dispersed in bitumen or heavy oil fractions was successfully developed. The produced catalyst particle size was found to be 111 nm (mode) with 80% of the particles in the range 57-176 nm. The effect of the main operating variables over the nano-particle retention and deposition was studied. Over 95% of particles retention was obtained, with no observable effect on the sandpack’s oil permeability. Concentration profiles along the porous media are similar for all tested conditions, with around 30% of nanoparticles at the entrance. Correlations for the profile and cumulative concentration are proposed. The morphological study of the resulting deposition showed particles deposited as large agglomerates for low temperature deposition tests, while high temperatures produced individually deposited particles near the entrance of the porous media.

The Ceramic Economy of Pre-Columbian Pacific Nicaragua (AD 1–1250)

description: Recent ceramic compositional analyses based on a combination of instrumental neutron activation analysis (INAA) and petrography demonstrate that our historic understanding of pre-Columbian ceramic production and distribution in Pacific Nicaragua—the northern sector of the Greater Nicoya archaeological region—has been somewhat less than accurate. Importantly, it also challenges ethnohistoric accounts, which have traditionally served as our basic framework of inquiry, and which suggest that changes in the social fabric and material culture across time are the result of in-migration and colonization by groups from Mesoamerica. The results of the current compositional analyses instead indicate continuity and internal change among local potting groups for more than 1,000 years, and coloured by longstanding social and economic connections with non-Mesoamerican groups in west-central Honduras, particularly the Comayagua Valley and Lake Yojoa regions. Importantly, this research also represents the first archaeological attempt to reconstruct the local volcanic environment and then articulate that with the compositional results. A total of 14 petrofabric groupings are proposed herein, with a particular focus on identification of pottery-producing centres in the Granada-Mombacho and Rivas-Ometepe areas of Pacific Nicaragua. Drawing on ceramic economy theory to structure and interpret the compositional results, this dissertation reconstructs the pre-Columbian ceramic economy in its ecological context (ca. AD 1–1250), highlighting patterns of ceramic production, consumption, and distribution at multiple scales of analysis. This framework is then further contextualized socially and interpreted utilizing a revised version of communities of practice theory designed to address the multiple scales inherent in the proposed reconstruction, including communities, constellations, and networks of practices. Based on the information presented in the results and interpretations, I address several key challenges that archaeologists working the region currently face. In final discussion I propose (1) a reconfiguration of the Greater Nicoya archaeological region, (2) an alternative explanation for difficulty in ‘seeing’ the local Ometepe period (AD 1250–1522) in the archaeological record, and (3) propose an alternative model to explain the presence of Oto-Manguean-speaking Chorotega groups in the region prior to European contact.

description: We continue investigation of soft breaking of BRST symmetry in the Batalin-Vilkovisky (BV) formalism beyond regularizations like dimensional ones used in our previous paper [JHEP 1110 (2011) 043, arXiv:1108.4820 [hep-th]]. We generalize a definition of soft breaking of BRST symmetry valid for general gauge theories and arbitrary gauge fixing. The gauge dependence of generating functionals of Green's functions is investigated. It is proved that such introduction of a soft breaking of BRST symmetry into gauge theories leads to inconsistency of the conventional BV formalism.

description: The ratio of shear viscosity ($η$) to entropy density ($s$) for an equilibrated system is investigated in intermediate energy heavy ion collisions below 100$A$ MeV within the framework of the Boltzmann-Uehling-Uhlenbeck (BUU) model . After the collision system almost reaches a local equilibration, the temperature, pressure and energy density are obtained from the phase space information and {$η/s$} is calculated using the Green-Kubo formulas. The results show that {$η$}/$s$ decreases with incident energy and tend towards a smaller value around 0.5, which is not so drastically different from the BNL Relativistic Heavy Ion Collider results in the present model.

description: The regularization of a new problem, namely the three-body problem, using 'similar' coordinate system is proposed. For this purpose we use the relation of 'similarity', which has been introduced as an equivalence relation in a previous paper (see \cite{rom11}). First we write the Hamiltonian function, the equations of motion in canonical form, and then using a generating function, we obtain the transformed equations of motion. After the coordinates transformations, we introduce the fictitious time, to regularize the equations of motion. Explicit formulas are given for the regularization in the coordinate systems centered in the more massive and the less massive star of the binary system. The 'similar' polar angle's definition is introduced, in order to analyze the regularization's geometrical transformation. The effect of Levi-Civita's transformation is described in a geometrical manner. Using the resulted regularized equations, we analyze and compare these canonical equations numerically, for the Earth-Moon binary system.

description: Open access GNSS signals have enabled the development of receivers that find their use spanning multitude of user segments. Owing to the long distance travel from the satellite to the user, the received signal level is very weak on or near earth. This is due to the free-space loss and, to a small extent, atmospheric losses. The signals arriving at the RF front-end can be affected by the presence of signals from other communication systems. Since GNSS has to coexist with other such systems, it is not abnormal to expect that even in normal operations, receivers experience interference. Additionally, undesirable signals can appear in the GNSS frequency band due to other man-made high power signal transmissions. The levels of these disturbing signals will determine the impact that they may have on the performance metrics of the receiver. Antenna array processing techniques are studied in GNSS as effective tools to mitigate interference in spatial and spatiotemporal domains. Analyzing the performance of array based mitigation methods involves many challenges, such as prohibition to propagate test interference signals and the challenge involved with the design and execution of cost-effective experimental setups. To reduce this burden, a new approach is proposed and developed and tested herein. Without specific filter design considerations, the array space-time processing (STP) results in distortions. This research also focuses on characterizing these degradations for different controlled signal scenarios and for live data from an antenna array. The capability of antenna array STP to mitigate the interference from near zone pseudolites and provide subsequent enhancements is studied in the latter part of the thesis. An array simulator is developed during the research and is effectively used for assessing STP measurement distortions. The characterization results show that distortions due to STP are significant and can lead to erroneous pseudorange measurements. From the simulation results, it is concluded that the antenna array STP methods are beneficial for interference mitigation in GPS-pseudolite combined signal environments.

description: The low temperature properties of double exchange model in triangular lattice are investigated via truncated polynomial expansion method (TPEM), which reduces the computational complexity and enables parallel computation. We found that for the half-filling case a stable 120-degree spin configuration phase occurs owing to the frustration of triangular lattice and is further stabilized by antiferromagnetic (AF) superexchange interaction, while a transition between a stable ferromagnetic (FM) phase and a unique flux phase with small finite-size effect is induced by AF superexchange interaction for the quarter-filling case.

description: Seasonal fluctuations in preferred food availability cause some non-human primate species to occasionally rely on less-preferred food types, called fallback foods. Periodic reliance on fallback foods has led, in some cases, to the evolution of morphological traits geared towards their exploitation. However, in species without these traits, fallback foods may instead beget behavioural modifications. Using 21 months of data, I analysed the use of fallback foods, and their behavioural consequences, in a population of highly frugivorous spider monkeys. Spider monkeys have previously been suggested to fall back on leaves, however I found that flowers, not leaves, were used as a fallback food. Seasonal reliance on flowers led to decreases in time spent travelling and increases in time spent feeding, as well as decreases in subgroup size. I interpreted these behaviours as an energy-minimizing strategy adopted to offset the low per-capita energy available in flowers as compared to fruit.

description: We determine the scalar part of the four-loop chiral dilatation operator for Leigh-Strassler deformations of N=4 super Yang-Mills. This is sufficient to find the four-loop anomalous dimensions for operators in closed scalar subsectors. This includes the SU(2) subsector of the (complex) beta-deformation, where we explicitly compute the anomalous dimension for operators with a single impurity. It also includes the "3-string null" operators of the cubic Leigh-Strassler deformation. Our four-loop results show that the rational part of the anomalous dimension is consistent with a conjecture made in arXiv:1108.1583 based on the three-loop result of arXiv:1008.3351 and the N=4 magnon dispersion relation. Here we find additional zeta(3) terms.

description: A series of bis(tridentate) cycloruthenated complexes have been synthesized and characterized for the dye-sensitized solar cell (DSSC). The title cycloruthenated complexes exhibit broader absorption profiles and cathodically shifted Ru(III)/Ru(II) redox potentials relative to their polypyridyl congeners. It is shown herein that derivatives of [Ru(tpy)(pbpy)]+ and [Ru(tpy)(dpb)]+ (tpy = 2,2':6',2''-terpyridine; pbpy = 6-phenyl-2,2'-bipyridine; dpb = 1,3-bis(2-pyridyl)benzene)), in particular, display a range of properties that enable high performance in the DSSC and offer insight into fundamental processes related to the sensitization of TiO2. This dissertation also documents how the light absorbing properties of [Ru(tpy)(pbpy)]+ complexes can be dramatically increased through the installation of a secondary organic triphenylamine (TPA) chromophore. These bichromic cycloruthenated complexes exhibit a broad (400-800 nm) and intense (ε up to 64.0 x 103 M-1 cm-1) absorption envelope throughout the visible spectrum, and can reach power-conversion efficiencies (PCE) as high as 8.02% (polypyridyl derivatives cannot achieve PCEs higher than 1%!). Modification of the TPA and anionic ring of the pbpy chelated with electron-donating groups (EDGs) and electron-withdrawing groups (EWGs) enables the independent modulation of the Ru(III)/Ru(II) and TPA•+/TPA0 redox potentials over 180 and 230 mV, respectively. The ability to tune each of the redox potentials independently results in acute synthetic control of the location of the highest-occupied molecular orbital (HOMO). This unique property offers the opportunity to turn on and off an intramolecular hole-transfer (after light-induced charge-transfer into TiO2) by confining the HOMO to the TPA or the metal chromophore, respectively. The interrogation of these dyes on the surface revealed many interesting features, including the open-circuit voltage (Voc) of the cell being acutely sensitive to the spatial proximity of the hole to the TiO2 surface. Metal-free organic sensitizers derived from ligand precursors, were synthesized to include S or O atoms on TPA and studied to directly probed the dye regeneration step. Our hypothesis that the soft polarizable sulfur atom would facilitate regeneration of the oxidized dye by the soft, polarizable I- ion was confirmed by transient absorption spectroscopy data: the sulfur-containing dye regenerated 25-fold faster the oxygen derivative. Tailoring the dye to facilitate regeneration results in improved PCEs. This work is important in that it provides atomic level resolution of how to prepare DSSC dyes.

description: The role of feedback from massive stars is believed to be a key element in the evolution of molecular clouds. We use high-resolution 3D SPH simulations to explore the dynamical effects of a single O7 star located at the centre of a molecular cloud with mass 10^4M_sun and radius 6.4pc. The initial internal structure of the cloud is characterised by its fractal dimension, D=2.0 - 2.8, and its log-normal density PDF. (i) As regards star formation, in the short term ionising feedback is positive, in the sense that star formation occurs much more quickly in gas that is compressed by the high pressure of the ionised gas. However, in the long term ionising feedback is negative, in the sense that most of the cloud is dispersed with an outflow rate of up to ~0.01M_sun/yr, on a timescale comparable with the sound-crossing time for the ionised gas (~1-2Myr), and triggered star formation is therefore limited to a few percent of the cloud's mass. (ii) As regards the morphology of the ionisation fronts (IFs) bounding the HII region and the systematics of outflowing gas, we distinguish two regimes. For low D<=2.2, the initial cloud is dominated by large-scale structures, so the neutral gas tends to be swept up into a few extended coherent shells, and the ionised gas blows out through a few large holes between these shells; we term these HII regions "shell-dominated". Conversely, for high D>=2.6, the initial cloud is dominated by small-scale structures, and these are quickly overrun by the advancing IF, thereby producing neutral pillars whilst the ionised gas blows out through a large number of small holes between the pillars; we term these HII regions "pillar-dominated". (iii) As regards the injection of bulk kinetic energy, by ~1Myr, the expansion of the HII region has delivered a rms velocity of ~6km/s; this represents less than 0.1% of the total energy radiated by the O7 star.

description: Supernova 1987A (SN1987A) in the neighbouring Large Magellanic Cloud offers a superb opportunity to follow the evolution of a supernova and its remnant in unprecedented detail. Recently, far-infrared (far-IR) and sub-mm emission was detected from the direction of SN1987A, which was interpreted as due to the emission from dust, possibly freshly synthesized in the SN ejecta. To better constrain the location and hence origin of the far-IR and sub-mm emission in SN1987A, we have attempted to resolve the object in that part of the electro-magnetic spectrum. We observed SN1987A during July-September 2011 with the Atacama Pathfinder EXperiment (APEX), at a wavelength of 350 micron with the Submillimetre APEX Bolometer CAmera (SABOCA) and at 870 micron with the Large APEX BOlometer CAmera (LABOCA). The 350-micron image has superior angular resolution (8") over that of the Herschel Space Observatory 350-micron image (25"). The 870-micron observation (at 20" resolution) is a repetition of a similar observation made in 2007. In both images, at 350 and 870 micron, emission is detected from SN1987A, and the source is unresolved. The flux densities in the new (2011) measurements are consistent with those measured before with Herschel at 350 micron (in 2010) and with APEX at 870 micron (in 2007). A higher dust temperature (approximately 33 K) and lower dust mass might be possible than what was previously thought. The new measurements, at the highest angular resolution achieved so far at far-IR and sub-mm wavelengths, strengthen the constraints on the location of the emission, which is thought to be close to the site of SN1987A and its circumstellar ring structures. These measurements set the stage for upcoming observations at even higher angular resolution with the Atacama Large Millimeter Array (ALMA).

title: Compiler-centric across-stack deep learning acceleration
Creators: name: Gibson, Perry
Publisher: name: University of Glasgow
Year: 2023

description: Optimizing the deployment of Deep Neural Networks (DNNs) is hard. Despite deep learning approaches increasingly providing state-of-the-art solutions to a variety of difficult problems, such as computer vision and natural language processing, DNNs can be prohibitively expensive, for example, in terms of inference time or memory usage. Effective exploration of the design space requires a holistic approach, including a range of topics from machine learning, systems, and hardware. The rapid proliferation of deep learning applications has raised demand for efficient exploration and acceleration of deep learning based solutions. However, managing the range of optimization techniques, as well as how they interact with each other across the stack is a non-trivial task. A family of emerging specialized compilers for deep learning, tensor compilers, appear to be a strong candidate to help manage the complexity of across-stack optimization choices, and enable new approaches. This thesis presents new techniques and explorations of the Deep Learning Acceleration Stack (DLAS), with the perspective that the tensor compiler will increasingly be the center of this stack. First, we motivate the challenges in exploring DLAS, by describing the experience of running a perturbation study varying parameters at every layer of the stack. The core of the study is implemented using a tensor compiler, which reduces the complexity of evaluating the wide range of variants, although still requires a significant engineering effort to realize. Next, we develop a new algorithm for grouped convolution, a model optimization technique for which existing solutions provided poor inference time scaling. We implement and optimize our algorithm using a tensor compiler, outperforming existing approaches by 5.1× on average (arithmetic mean). Finally, we propose a technique, transfer-tuning, to reduce the search time required for automatic tensor compiler code optimization, reducing the search time required by 6.5× on average. The techniques and contributions of this thesis across these interconnected domains demonstrate the exciting potential of tensor compilers to simplify and improve design space exploration for DNNs, and their deployment. The outcomes of this thesis enable new lines of research to enable machine learning developers to keep up with the rapidly evolving landscape of neural architectures and hardware.

description: The impact of rapid rotation on stellar evolution theory remains poorly understood as of today. Vega is a special object in this context as spectroscopic and interferometric studies have shown that it is a rapid rotator seen nearly pole one, a rare orientation particularly interesting for seismic studies. In this paper we present a first systematic search for pulsations in Vega. The goal of the present work is to detect for the first time pulsations in a rapidly rotating star seen nearly pole-on. Vega was monitored in quasi-continuous high-resolution echelle spectroscopy. A total of 4478 spectra were obtained within 3 individual runs in 2008, 2009 and 2010 at high resolution. This data set should represent the most extensive high S/N, high resolution quasi-continuous survey obtained on Vega as of today. Equivalent photospheric absorption profiles were calculated for the stellar spectrum, but also for the telluric lines acting as a radial velocity reference. Residual velocities were analysed and periodic low amplitude variations, potentially indicative of stellar pulsations, detected. All three data sets revealed the presence of residual periodic variations: 5.32 and 9.19 c/d, (A approx 6 m/s) in 2008, 12.71 and 13.25 c/d, (A approx 8 m/s) in 2009 and 5.42 and 10.82 c/d, (A approx 3-4 m/s) in 2010. A Lomb-Scargle periodogram of each velocity bin of the equivalent profile was performed for the 2010 run, not showing the presence of any higher order nrp mode. It is too early to conclude that the variations are due to stellar pulsations, and a confirmation of the detection with a highly stable spectrograph is a necessary next step. If pulsations are confirmed, their very small amplitudes show that the star would belong to a category of very "quiet" pulsators.

description: We say that there is a representation of the universal algebra B in the universal algebra A if the set of endomorphisms of the universal algebra A has the structure of universal algebra B. Therefore, the role of representation of the universal algebra is similar to the role of symmetry in geometry and physics. Morphism of the representation is the mapping that conserves the structure of the representation. Exploring of morphisms of the representation leads to the concepts of generating set and basis of representation. The set of automorphisms of the representation of the universal algebra forms the group. Twin representations of this group in basis manifold of the representation are called active and passive representations. Passive representation in basis manifold is underlying of concept of geometric object and the theory of invariants of the representation of the universal algebra.

description: Quantum communication founds on the possibility to encode quantum states into photons and allows, for instance, the provable secure distribution of encryption keys. Despite a lot of progress during the past two decades, quantum communication still faces a distance barrier, which can be overcome by quantum repeaters whose currently most challenging ingredient is a memory for quantum states of light. In addition to robustness and ease of use, the requirements for such a quantum memory include high fidelity quantum state storage and the preservation of entanglement, sufficiently long storage time with on-demand recall, high efficiency, large bandwidth, and high multimode capacity. Six years ago, some of these properties had already been demonstrated using atomic vapor. However, practical solid-state memories were virtually unexplored in view of quantum state storage. The main goal of this thesis was to realize a solid-state quantum memory for light with emphasis on meeting requirements for long distance quantum communication. First, we identified a potential material candidate, a thulium doped lithium niobate waveguide, and conducted spectroscopic investigations to assess its suitability for quantum state storage using a photon-echo type approach. Next, we demonstrated that our storage device is suitable for high fidelity quantum state storage and for the storage of photonic entanglement, and that its large spectral multimode capacity allows for on-demand selective recall in conjunction with standard spectral filters and frequency shifters. In addition, by performing two-photon interference experiments and Bell-State measurements, we found that our memory preserves not only quantum information, but, more generally, the entire photonic wave function, which further confirms its suitability for quantum repeaters as well as for linear optics quantum computers. Finally, we showed that our integrated device also allows for general temporal and spectral manipulation of individual quantum optical pulses, which paves the way towards on-chip quantum optical processors. While more work remains to be done, in particular to improve memory efficiency and storage time, the large number of achievements, together with known ways to overcome the remaining obstacles, makes us confident that a quantum memory suitable for quantum repeaters will soon be built.

description: Cancer patient navigation has become an important aspect of cancer care to support and guide patients through the health care system. In Canada, registered nurses commonly take on this role. The purpose of this study was to gain a better understanding of the process of cancer patient navigation from the perspective of registered nurses who work in the navigator role. Using constructivist grounded theory methodology, I interviewed nine cancer patient navigators in the province of Alberta, to examine their experiences and perspectives of their role. I analyzed the data using constant comparison and six interrelated categories emerged. This analysis led to the co-construction of the theory of Coming Alongside a Patient Throughout Their Cancer Journey. Findings from this study bring a new understanding of navigation as a process and highlight a different conceptualization of time, which sets this study apart from other research.
Recent developments in business method patents in the U.S. and the implication to the People’s Republic of China : a comparative perspective
Creators: name: Niu, Jinghui
Publisher: name: University of British Columbia
Year: 2010

description: A detailed and structured comparative study concerning business method patents (BMPs) is conducted between Chinese and the United States patent regime. This comparative study covers BMPS' concepts, jurisprudential history, related terminologies, theoretical rationales, functional cores of the two countries' legal and administrative systems, as well as paradigms for public opinions towards BMPs. The comparisons are based on the most recently updated legislative and judiciary developments in the two countries. Following this comparison is a philosophical and economic analysis on implications of BMPs in general. Examples of how BMPs work in real-world in the two countries' administration, and why BMPs are important and can affect businesses strategically, are given. Then the issue of cross-border enforcement, which is generally thought of as a particularly challenging aspect of BMPs, is touched on. In the final chapter, placed in a globalized context, the concept of externalities in economics is introduced into the analysis of the BMPs' value for a country's innovation and entrepreneurial environment. The purpose of this thesis is to explore important dimensions of BMPs from an updated and more globalized angle, providing a perspective for policymakers, practitioners and scholars in the field, especially for those who are interested in the two countries being researched.
Controlling the temperature sensitivity of DNA-mediated colloidal interactions through competing linkages

description: We propose a new strategy to improve the self-assembly properties of DNA-functionalised colloids. The problem that we address is that DNA-functionalised colloids typically crystallize in a narrow temperature window, if at all. The underlying reason is the extreme sensitivity of DNA-mediated interactions to temperature or other physical control parameters. We propose to widen the window for colloidal crystallization by exploiting the competition between DNA linkages with different nucleotide sequences, which results in a temperature-dependent switching of the dominant bond type. Following such a strategy, we can decrease the temperature dependence of DNA-mediated self assembly to make systems that can crystallize in a wider temperature window than is possible with existing systems of DNA functionalised colloids. We report Monte Carlo simulations that show that the proposed strategy can indeed work in practice for real systems and specific, designable DNA sequences. Depending on the length ratio of the different DNA constructs, we find that the bond switching is either energetically driven (equal length or `symmetric' DNA) or controlled by a combinatorial entropy gain (`asymmetric' DNA), which results from the large number of possible binding partners for each DNA strand. We provide specific suggestions for the DNA sequences with which these effects can be achieved experimentally.

description: Os inibidores das Janus Associated Kinases (JAK) são uma estratégia recente direcionada para o tratamento de diversas patologias como a artrite reumatoide, a psoríase, a alopecia areata e diversos tipos de cancro. Contudo, estes medicamentos estão associados a reações adversas graves, estando subentendida a importância da monitorização farmacoterapêutica dos doentes submetidos a estes tratamentos. O objetivo do estudo foi efetuar uma revisão dos diferentes inibidores das JAK aprovados no mercado nacional e internacional, as suas indicações terapêuticas e efeitos adversos, bem como as potenciais indicações em investigação dos inibidores das JAK já introduzidos no mercado farmacêutico. Foi, também, efetuada uma revisão dos principais inibidores das JAK que se encontram em investigação clínica.

Efetuou-se uma revisão bibliográfica do Resumo das Características do Medicamento (RCM) dos inibidores das JAK disponíveis no mercado farmacêutico, bem como uma pesquisa na base de dados eletrónica da PubMed, recorrendo aos termos «JAK inhibitors», «Janus Associated Kinases inhibitors» e «Janus Kinases inhibitors». Foram considerados os artigos publicados desde janeiro de 2014 até janeiro de 2015, tendo sido incluídos 92 artigos na revisão efetuada. Foram também consultadas as bases de dados da European Medicines Agency (EMA) e da United States Food and Drug Administration (FDA) de forma a identificar os inibidores das JAK autorizados na prática clínica.

Atualmente, apenas o ruxolitinib e o tofacitinib estão disponíveis no mercado farmacêutico, subsistindo, ainda, a aprovação do oclatinib enquanto medicamento de uso veterinário. Ambos os fármacos de uso humano apresentam efeitos adversos major ao nível hematológico e imunológico, facto que reforça a importância do papel do farmacêutico no acompanhamento dos doentes implicados nestes tratamentos. Encontram-se em estudos pré-clínicos e clínicos inúmeras moléculas que tentam provar o seu potencial no tratamento de diversas patologias de natureza autoimune, inflamatória e oncológica. Desta forma, é, ainda, necessário aprofundar o conhecimento nesta área por forma a ultrapassar os riscos inerentes à terapia com estes agentes, riscos esses que, contrabalançados com os benefícios do seu uso clínico, têm comprometido o avanço de diversos inibidores das JAK com potencial terapêutico demonstrado.
