description: The world of today is increasingly dependant on a functional, globalized economy. The defence and security establishments’ reliance on supplies and logistics is not new. First responders rely on many tools and systems that are critical to their endeavours. Somewhat disjoint at first glance, these domains share a common need for complex physical or logistical infrastructures such as power plants, ports, supply chains, to name a few examples.All of these are potentially vulnerable to attacks, disruptions, breakdowns, or other activities that disable the infrastructure and consequently cause important physical or economic damage. An obligation exists to protect these critical infrastructures and a decision support system that is able to detect, identify, and mitigate the risk of unwanted events would be invaluable in preventing the disastrous consequences of compromised infrastructure.This thesis explores the design and application of such a system. It starts with a pre-existing, actively researched risk management framework and proposes a methodology to apply it in new contexts, as well as contributions to provide the framework with the ability to solve new problems. Relevant case studies in critical infrastructure protection are presented, as well as applications of the developed methodology with the proposed modifications when suitable. Simulations, results, and insightful discussions are provided for each of the case studies. Finally, research trends, future work, and a conclusion are given, completing this thesis.

description: Using VLT/SPHERE near-infrared dual-band imaging and integral field spectroscopy we discovered an edge-on debris disk around the 17\,Myr old A-type member of the Scorpius-Centaurus OB association HD 110058. The edge-on disk can be traced to about 0.6" or 65 AU projected separation. In its northern and southern wings, the disk shows at all wavelengths two prominent, bright and symmetrically placed knots at 0.3" or 32 AU from the star. We interpret these knots as a ring of planetesimals whose collisions may produce most of the dust observed in the disk. We find no evidence for a bow in the disk, but we identify a pair of symmetric, hook-like features in both wings. Based on similar features in the Beta Pictoris disk we propose that this wing-tilt asymmetry traces either an outer planetesimal belt that is inclined with respect to the disk midplane or radiation-pressure-driven dust blown out from a yet unseen, inner belt which is inclined with respect to the disk midplane. The misaligned inner or outer disk may be a result of interaction with a yet unseen planet. Overall, the disk geometry resembles the nearby disk around Beta Pictoris, albeit seen at smaller radial scales.

Realizing the niche's breadth: inferring ecological process with species generalism
Creators: name: McChesney, Jasper
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Various ecological processes affect generalist and specialist species differently. By measuring niche breadth in communities, we can infer those processes. Simulation models provided proofs of concept for three analyses that were applied to Carolina Vegetation Survey data. (1) A refined method for estimating niche breadth using co-occurrence data is presented. (2) It is shown that sampling grain can affect the quality of such estimates and also illuminate the scale of the processes limiting species' distributions. Trees showed surprising sensitivity to spatial variation at a small scale (10cm2) while herbs responded more strongly at a larger one (1000m2). (3) The relationship between assemblage richness and the generalism of its members is explored. There is evidence that in some community types, important factors affecting richness include an evolutionary generalism-competition trade-off and the availability of specialist competitors in the local pool.

description: This study reports the results of regression analyses that examined the contribution of parent career modeling to the outcomes of student engagement, school valuing, and future time perspective. The study was conducted with 6th grade students, who were surveyed at both the beginning of the school-year and at the end of the school-year using self-report scale items for the independent and dependent constructs. Baseline levels and demographic variables, such as gender, socioeconomic status, family structure, and race were controlled for in the regression analysis to determine the unique contribution by parent career modeling. It was found that parent career modeling contributes significantly to all three of the dependent variables. This study provides evidence for using parent career modeling in interventions aimed at increasing student engagement, student valuing of school, and future time perspective.

description: We analysed 385 galactic spectra from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) that belong to the catalog of isolated pairs of galaxies by Karachentsev. The spectra corresponds to physical pairs of galaxies as defined by V $\leq$ 1200 Km/s and a pair separation $\leq$ 100 kpc. We search for the incidence of nuclear activity, both thermal (star-forming) and non-thermal -Active Galactic Nuclei (AGN). After a careful extraction of the nuclear spectra, we use diagnostic diagrams and find that the incidence of AGN activity is 48 \% in the paired galaxies with emission lines and 40\% for the total sample (as compared to $\sim$ 43 \% and 41\% respectively in a sample of isolated galaxies). These results remain after dissecting the effects of morphological type and galactic stellar mass (with only a small, non significant, enhancement of the AGN fraction in pairs of objects). These results suggest that weak interactions are not necessary or sufficient to trigger low-luminosity AGN. Since the fraction of AGN is predominant in early type spiral galaxies, we conclude that the role of a bulge, and a large gas reservoir are both essential for the triggering of nuclear activity. The most striking result is that type 1 galaxies are almost absent from the AGN sample. This result is in conflict with the Unified Model, and suggests that high accretion rates are essential to form the Broad Line Region in active galaxies.

description: The ability to synthesis well-ordered two-dimensional materials under ultra-high vacuum and directly characterize them by other techniques in-situ can greatly advance our current understanding on their physical and chemical properties. In this paper, we demonstrate that iso-oriented α-MoO3 films with as low as single monolayer thickness can be reproducibly grown on SrTiO3(001) (STO) substrates by molecular beam epitaxy ( (010)MoO3 || (001)STO, [100]MoO3 || [100]STO or [010]STO) through a self-limiting process. While one in-plane lattice parameter of the MoO3 is very close to that of the SrTiO3 (aMoO3 = 3.96 Å, aSTO = 3.905 Å), the lattice mismatch along other direction is large (~5%, cMoO3 = 3.70 Å), which leads to relaxation as clearly observed from the splitting of streaks in reflection high-energy electron diffraction (RHEED) patterns. A narrow range in the growth temperature is found to be optimal for the growth of monolayer α-MoO3 films. Increasing deposition time will not lead to further increase in thickness, which is explained by a balance between deposition and thermal desorption due to the weak van der Waals force between α-MoO3 layers. Lowering growth temperature after the initial iso-oriented α-MoO3 monolayer leads to thicker α-MoO3(010) films with excellent crystallinity.

description: We present VLT/SPHERE adaptive optics imaging in Y$-$, J$-$, H$-$, and K-bands of the HD 100453 system and the discovery of a two-armed spiral structure in a disk extending to 0.37" ($\sim$42 AU) from the star, with highly symmetric arms to the Northeast and Southwest. Inside of the spiral arms, we resolve a ring of emission from 0.18"-0.25" ($\sim$21-29 AU). By assuming that the ring is intrinsically circular we estimate an inclination of $\sim$34$^{o}$ from face-on. We detect dark crescents on opposite sides (NW and SE) which begin at 0.18" and continue to radii smaller than our inner working angle of 0.15", which we interpret as the signature of a gap at $\lesssim$21 AU that has likely been cleared by forming planets. We also detect the $\sim$120 AU companion HD 100453 B, and by comparing our data to 2003 HST/ACS and VLT/NACO images we estimate an orbital period of $\sim$850 yr. We discuss what implications the discovery of the spiral arms and finer structures of the disk may have on our understanding of the possible planetary system in HD 100453, and how the morphology of this disk compares to other related objects.

Polychromatic X-ray CT Image Reconstruction and Mass-Attenuation Spectrum Estimation
Creators: name: Gu, Renliang

Year: 2015
Subjects: subject: Methodology (stat.ME)

description: We develop a method for sparse image reconstruction from polychromatic computed tomography (CT) measurements under the blind scenario where the material of the inspected object and the incident-energy spectrum are unknown. We obtain a parsimonious measurement-model parameterization by changing the integral variable from photon energy to mass attenuation, which allows us to combine the variations brought by the unknown incident spectrum and mass attenuation into a single unknown mass-attenuation spectrum function; the resulting measurement equation has the Laplace integral form. The mass-attenuation spectrum is then expanded into first order B-spline basis functions. We derive a block coordinate-descent algorithm for constrained minimization of a penalized negative log-likelihood (NLL) cost function, where penalty terms ensure nonnegativity of the spline coefficients and nonnegativity and sparsity of the density map. The image sparsity is imposed using total-variation (TV) and $\ell_1$ norms, applied to the density-map image and its discrete wavelet transform (DWT) coefficients, respectively. This algorithm alternates between Nesterov's proximal-gradient (NPG) and limited-memory Broyden-Fletcher-Goldfarb-Shanno with box constraints (L-BFGS-B) steps for updating the image and mass-attenuation spectrum parameters. To accelerate convergence of the density-map NPG step, we apply a step-size selection scheme that accounts for varying local Lipschitz constant of the NLL. We consider lognormal and Poisson noise models and establish conditions for biconvexity of the corresponding NLLs. We also prove the Kurdyka-Łojasiewicz property of the objective function, which is important for establishing local convergence of the algorithm. Numerical experiments with simulated and real X-ray CT data demonstrate the performance of the proposed scheme.
Deterministic Annealing Based Optimization for Zero-Delay Source-Channel Coding in Networks

description: This paper studies the problem of global optimization of zero-delay source-channel codes that map between the source space and the channel space, under a given transmission power constraint and for the mean square error distortion. Particularly, we focus on two well known network settings: the Wyner-Ziv setting where only a decoder has access to side information and the distributed setting where independent encoders transmit over independent channels to a central decoder. Prior work derived the necessary conditions for optimality of the encoder and decoder mappings, along with a greedy optimization algorithm that imposes these conditions iteratively, in conjunction with the heuristic noisy channel relaxation method to mitigate poor local minima. While noisy channel relaxation is arguably effective in simple settings, it fails to provide accurate global optimization in more complicated settings considered in this paper. We propose a powerful non-convex optimization method based on the concept of deterministic annealing -- which is derived from information theoretic principles and was successfully employed in several problems including vector quantization, classification and regression. We present comparative numerical results that show strict superiority of the proposed method over greedy optimization methods as well as prior approaches in literature.

description: $Γ$-structures are weak forms of multiplications on closed oriented manifolds. As shown by Hopf the rational cohomology algebras of manifolds admitting $Γ$-structures are free over odd degree generators. We prove that this condition is also sufficient for the existence of $Γ$-structures on manifolds which are nilpotent in the sense of homotopy theory. This includes homogeneous spaces with connected isotropy groups. Passing to a more geometric perspective we show that on compact oriented Riemannian symmetric spaces with connected isotropy groups and free rational cohomology algebras the canonical products given by geodesic symmetries define $Γ$-structures. This extends work of Albers, Frauenfelder and Solomon on $Γ$-structures on Lagrangian Grassmannians.

description: We study the Andrews-Gordon-Bressoud (AGB) generalisations of the Rogers-Ramanujan q-series identities in the context of cylindric partitions. We recall the definition of r-cylindric partitions, and provide a simple proof of Borodin's product expression for their generating functions, that can be regarded as a limiting case of an unpublished proof by Krattenthaler. We also recall the relationships between the r-cylindric partition generating functions, the principal characters of affine sl_r algebras, the M^{r, r+d}_r minimal model characters of W_r algebras, and the r-string abaci generating functions, as well as the relationships between them, providing simple proofs for each. We then set r=2, and use 2-cylindric partitions to re-derive the AGB identities as follows. Firstly, we use Borodin's product expression for the generating functions of the 2-cylindric partitions with infinitely-long parts, to obtain the product sides of the AGB identities, times a factor (q; q)_{\infty}^{-1}, which is the generating function of ordinary partitions. Next, we obtain a bijection from the 2-cylindric partitions, via 2-string abaci, into decorated versions of Bressoud's restricted lattice paths. Extending Bressoud's method of transforming between restricted paths that obey different restrictions, we obtain sum expressions with manifestly non-negative coefficients for the generating functions of the 2-cylindric partitions which contains a factor (q; q)_{\infty}^{-1}. Equating the product and sum expressions of the same 2-cylindric partitions, and canceling a factor of (q; q)_{\infty}^{-1} on each side, we obtain the AGB identities.

description: Motivated by a recent work on asymptotically AdS_4 black holes in M-theory, we investigate the thermodynamics and thermodynamical geometry of AdS black holes from M2 and M5-branes. Concretely, we consider AdS black holes in AdS_{p+2}\times S^{11-p-2}, where p=2,5 by interpreting the number of M2 (and M5-branes) as a thermodynamical variable. We study the corresponding phase transition to examine their stabilities by calculating and discussing various thermodynamical quantities including the chemical potential. Then, we compute the thermodynamical curvatures from the Quevedo metric for M2 and M5-branes geometries to reconsider the stability of such black objects. The Quevedo metric singularities recover similar stability results provided by the phase transition program.

The roles of Canoe (Cno) in the regulation of morphological changes during Drosophila embryogenesis
Creators: name: Jung, Kuo-chen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: The fundamental question for developmental biologists is to understand how fertilized eggs become mature multicellular adults. During this process, cells undergo morphogenesis to form different cell and tissue shapes. Accomplishing accurate morphogenesis in organisms requires several structural protein systems: polarity proteins define different membrane domains and cell polarity, a cytoskeletal network provides the driving force to modify cell shape, and adherens junctions (AJ) maintain whole tissue integrity. Linker proteins between the AJ and the cytoskeleton ensure coordinated cell morphological changes. In the Peifer lab, we use Drosophila as a system to study these events. Failure of proper cell morphological changes causes abnormal embryonic processes. I characterized cno phenotypes during dorsal closure to investigate Cno function in later developmental stages during Drosophila embryogenesis. I also examined Rap1 and Cno localization in different developmental stages to help understand how Rap1 and Cno function temporally.

description: Following earlier findings, we argue that the low-$|t|$ structure in the elastic diffractive cone, recently reported by the TOTEM Collaboration at $8$ TeV, is a consequence of the threshold singularity required by $t-$channel unitarity, such as revealed earlier at the ISR. By using simple Regge-pole models, we analyze the available data on the $pp$ elastic differential cross section in a wide range of c.m. energies, namely those from ISR to LHC8, obtaining good fits of all datasets. This study hints at the fact that the non-exponential behaviour observed at LHC8 is a recurrence of the low-$|t|$ "break" phenomenon, observed in the seventies at ISR, being induced by the presence of a two-pion loop singularity in the Pomeron trajectory.

description: The diversification of societies as a result of migration flows has reached unprecedented proportions and generated its own share of challenges. In response to these challenges, European governments rely increasingly on civic integration policies, tying the obtention of rights and statuses to the completion of strict requirements that typify national citizenship, including linguistic competences. As an alternative to mandatory, time-intensive, and often inefficient language requirements, local levels of government can play a role in promoting the linguistic integration of immigrants while recognising diversity and fostering social cohesion. Drawing on the experience of three Human Rights Cities in Europe, this thesis suggests a set of best practices that can guide the work of local governments and strengthen their role as key human rights actors.
Combined Gene Therapy of siRNA and Apoptosis Inducing Factor Generated from a Single Transcriptional Event
Creators: name: Hung, Hsin-I
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: The goal of this project is to test the hypothesis that a single transcriptional event driven by RNA polymerase II promoter driven siRNA expression plasmid that utilized RNA splicing mechanism. During this event, a specific siRNA to a target oncogene, forms from the spliced intron; meanwhile a therapeutic protein is established after rejoining of the exon fragments. In this case, the well-known, strong RNA polymerase II (CMV) promoter was used to produce an siRNA against several well known oncogenes and a therapeutic protein, Apoptosis Inducing Factor (AIF), as a dual therapeutic to induce tumor cells apoptosis simultaneously from a single plasmid construct. By using this splicing approach with 2 different targeting mechanisms (i.e., oncogene inhibition by siRNA and therapeutic protein expression), we expect to see a synergistic effect from our novel RNA polymerase II promoter-driven plasmid. It was demonstrated that the plasmid construct achieved up to 40 percent siRNA inhibition, as well as increased apoptosis of cells transfected after cloning of the therapeutic exon component. In addition, by using a DNA-vector driven siRNA expression system, we can reduce the cost of producing siRNA and increase the duration of siRNA efficacy to achieve long term effects of gene silencing. Thus, by utilizing the combination of these 2 different targeting mechanisms from the RNA splicing process, we expected that the strategy will bring us a new affordable and promising way for efficient cancer cell targeting and treatment. Combined with the consistent and satisfactory lipid-based delivery system previously described by our lab (Li & Huang, 1997; Li et al, 2008; Li & Huang, 2006), we anticipate a greatly improved cancer targeting therapy.

description: We study the GIT compactifications of pairs formed by a hypersurface and a hyperplane. We provide a general setting to characterize all polarizations which give rise to different GIT quotients. Furthermore, we describe a finite set of one-parameter subgroups sufficient to determine the stability of any GIT quotient. We characterize all maximal orbits of non stable and strictly semistable pairs, as well as minimal closed orbits of strictly semistable pairs. Our construction gives natural compactifications of the space of log smooth pairs for Fano and Calabi-Yau hypersurfaces.

description: This is the line of inquiry developed for the topic covered under the title "Compliance, Avoidance, and Evasion in Taxation: The Role of Professionals – The Gray Area," which is a research activity focused on the intricate realm of the "gray area," the nebulous zone where taxpayers’ conducts waver between legality and illegality. Inter alia, the research looks at how certain tax practices, often unethical and abusive, are facilitated by tax professionals through aggressive tax strategies, the establishment of shell entities, and the use of tax havens. Furthermore, the research underscores the interconnectedness of corrupt practices and tax malfeasance globally. The relationship between corporate power, the tax consultancy sector, revolving door phenomena, and other unethical practices can lead to state capture, tax violations, and systemic corruption. The convoluted nature of tax regimes offers major accounting and legal firms a unique vantage point, risking the manipulation of political decisions. Such practices, termed "tax abuse", cover not only overt tax offenses like evasion but also the clever, yet legal, exploitation of loopholes against the spirit of the law. The research encompasses a cohesive and interconnected set of research questions, serving as the groundwork for subsequent investigations. These investigations will involve various components, including a systematic review of existing literature and the research outcomes generated during the VIRTEU project research activities. The aim of this study is to contribute to the cumulative understanding of the current state of knowledge concerning the above-mentioned research topic.

description: The H3+ molecule has been detected in many lines of sight within the central molecular zone (CMZ) with exceptionally large column densities and unusual excitation properties compared to diffuse local clouds. The detection of the (3,3) metastable level has been suggested to be the signature of warm and diffuse gas in the CMZ. We use the Meudon PDR code to re-examine the relationship between the column density of H3+ and the cosmic-ray ionization rate, $ζ$, up to large values of $ζ$. We study the impact of the various mechanisms that can excite H3+ in its metastable state. We produce grids of PDR models exploring different parameters ($ζ$, size of clouds, metallicity) and infer the physical conditions that best match the observations toward ten lines of sight in the CMZ. For one of them, Herschel observations of HF, OH+, H2O+, and H3O+ can be used as additional constraints. We check that the results found for H3+ also account for the observations of these molecules. We find that the linear relationship between N(H3+) and $ζ$ only holds up to a certain value of the cosmic-ray ionization rate, which depends on the proton density. A value $ζ\sim 1 - 11 \times 10^{-14}$ s$^{-1}$ explains both the large observed H3+ column density and its excitation in the metastable level (3,3) in the CMZ. It also reproduces N(OH+), N(H2O+) and N(H3O+) detected toward Sgr B2(N). We confirm that the CMZ probed by H3+ is diffuse, nH $\lesssim$ 100 cm-3 and warm, T $\sim$ 212-505 K. This warm medium is due to cosmic-ray heating. We also find that the diffuse component probed by H3+ must fill a large fraction of the CMZ. Finally, we suggest the warm gas in the CMZ enables efficient H2 formation via chemisorption sites as in PDRs. This contributes to enhance the abundance of H3+ in this high cosmic-ray flux environment.

description: It is possible to prepare classical optical beams which cannot be characterized by a tensor product of vectors describing each of their degrees of freedom. Here we report the experimental creation of such a non-separable, tripartite GHZ-like state of path, polarization and transverse modes of a classical laser beam. We use a Mach-Zehnder interferometer with an additional mirror and other optical elements to perform measurements that violate Mermin's inequality. This demonstration of a classical optical analogue of tripartite entanglement paves the path to novel optical applications inspired by multipartite quantum information protocols.

description: Modeling and predicting the popularity of online content is a significant problem for the practice of information dissemination, advertising, and consumption. Recent work analyzing massive datasets advances our understanding of popularity, but one major gap remains: To precisely quantify the relationship between the popularity of an online item and the external promotions it receives. This work supplies the missing link between exogenous inputs from public social media platforms, such as Twitter, and endogenous responses within the content platform, such as YouTube. We develop a novel mathematical model, the Hawkes intensity process, which can explain the complex popularity history of each video according to its type of content, network of diffusion, and sensitivity to promotion. Our model supplies a prototypical description of videos, called an endo-exo map. This map explains popularity as the result of an extrinsic factor - the amount of promotions from the outside world that the video receives, acting upon two intrinsic factors - sensitivity to promotion, and inherent virality. We use this model to forecast future popularity given promotions on a large 5-months feed of the most-tweeted videos, and found it to lower the average error by 28.6% from approaches based on popularity history. Finally, we can identify videos that have a high potential to become viral, as well as those for which promotions will have hardly any effect.

Year: 2018

description: Parallel to the world's rising urbanization trend, shifting patterns of large wet weather disturbances - more specifically, hurricanes - are raising concerns in coastal areas where many cities are located. A shift in studying these occurrences is paramount. This thesis addresses the following question: in what ways can the inclusion of social vulnerability studies and environmental justice, often developed outside of the field of urban ecology, contribute to a critical understanding of urban socioecological uncertainties following hurricanes? To answer this question, this thesis reviews the literature on urban ecology and examines how scholarship that emphasizes justice, vulnerabilities, and spatialities can expand the field's applicability to the study of natural disasters. In this thesis, I make claims for a critical urban ecology, which includes an integrated, holistic, and critical understanding of the social, economic, biogeophysical, and built parts of urban systems.

description: Genomic surveillance of SARS-CoV-2 was rapidly implemented in Portugal by the National Institute of Health in collaboration with a nationwide consortium of >50 hospitals/laboratories. Here, we track the geotemporal spread of a SARS-CoV-2 variant with a mutation (D839Y) in a potential host-interacting region involving the Spike fusion peptide, which is a target motif of anti-viral drugs that plays a key role in SARS-CoV-2 infectivity. The Spike Y839 variant was most likely imported from Italy in mid-late February and massively disseminated in Portugal during the early epidemic, becoming prevalent in the Northern and Central regions of Portugal where it represented 22% and 59% of the sampled genomes, respectively, by April 30th. Based on our high sequencing sampling during the early epidemics [15.5% (1275/8251) and 6.0% (1500/24987) of all confirmed cases until the end of March and April, respectively)], we estimate that, between March 14th and April 9th (covering the epidemic exponential phase) the relative frequency of the Spike Y839 variant increased at a rate of 12.1% (6.1%–18.2%, CI 95%) every three days, being potentially associated with 24.8% (20.8-29.7%, CI 95%; 3177-4542 cases, CI 95%) of all COVID-19 cases in Portugal during this period. Our data supports population/epidemiological (founder) effects contributing to the Y839 variant superspread. The potential existence of selective advantage is also discussed, although experimental validation is required. Despite huge differences in genome sampling worldwide, SARS-CoV-2 Spike D839Y has been detected in 13 countries in four continents, supporting the need for close surveillance and functional assays of Spike variants.

description: Razionale Il dolore post-chirurgico è un aspetto clinico rilevante nella pratica quotidiana che, se cronicizzato, porta a un mantenimento del dolore nel tempo, compromettendo la salute e la qualità della vita dei pazienti. La International Association Study of Pain (IASP) ha definito il dolore cronico post-chirurgico come un dolore che si sviluppa o aumenta d’intensità dopo una procedura chirurgica e persiste per più di 3 mesi dopo l'intervento. Ha un’incidenza che varia in base al tipo d’intervento chirurgico. Il dolore post-operatorio dovrebbe essere alleviato il prima e il più efficacemente possibile per ridurre la sofferenza percepita dal paziente, promuovere il processo di guarigione e prevenire le complicanze. Dagli studi in letteratura sembrerebbe che l’esercizio terapeutico abbia un ruolo importante nella gestione del dolore muscoloscheletrico dove la riduzione del dolore non sembrerebbe essere correlata a una modifica degli impairment anatomo-funzionali (aumento di forza, endurance, mobilità...), facendo pensare ad una maggiore azione dell’esercizio terapeutico su meccanismi centrali-cognitivi. Ad oggi però non è ancora possibile fornire una motivazione univoca e certa che giustifichi l’efficacia dell’esercizio terapeutico sulla gestione del dolore e pochi studi analizzano la corretta dose di somministrazione dell’esercizio, soprattutto dopo chirurgia muscoloscheletrica. Inoltre vi è una notevole variabilità degli interventi previsti e le prove attuali forniscono una guida limitata ed eterogenea per la pratica fisioterapica. Considerando il ruolo positivo dell’esercizio terapeutico sul dolore, lo scopo di questa revisione sistematica della letteratura è quello di osservare l’effetto dell’esercizio terapeutico sul dolore post-chirurgico e di indicarne la posologia più efficace. Quesito di ricerca In pazienti adulti con esiti di chirurgia muscoloscheletrica di arti e colonna vertebrale, l’esercizio terapeutico è efficace nel ridurre il dolore post-chirurgico?
