description: Background: Resting tremor is common in Parkinson’s disease (PD), but up to 47% of PD patients have action tremor, which is sometimes resistant to medications. Deep brain stimulation (DBS) of the ventral intermediate nucleus (VIM) of the thalamus or subthalamic nucleus (STN) is effective for medication-refractory tremor in PD, though it remains unclear whether STN DBS is as effective as VIM DBS for postural/action tremor related to PD. Methods: We carried out a single-center retrospective review of patients with medication-refractory resting, postural, and action PD tremor, treated with either VIM or STN DBS between August 2004 and March 2014. We assessed the degree of improvement using items 20 and 21 of the Unified Parkinson’s Disease Rating Scale (UPDRS) motor scale and examined the proportion of patients achieving tremor arrest. Results: A total of 18 patients were analyzed, 10 treated with STN and eight treated with VIM, with similar off-medication motor UPDRS scores. There was no significant difference in improvement in tremor scores or in the proportion of patients experiencing tremor arrest between the two stimulation sites. Overall, 56% and 72% of patients experienced complete absence of postural/action tremor and resting tremor, respectively, at last follow-up. Discussion: This study demonstrated excellent outcomes on both resting and postural/action tremor after either VIM or STN DBS. Resting tremor improved to a greater degree than postural/action tremor in both groups. These results suggest that a large randomized controlled trial is needed to show a superior effect of one target on PD tremor.

description: Η παρούσα διδακτορική διατριβή εξετάζει την επίδραση των μέτρων πολιτικής κατά του καπνίσματος και το ρόλο των ψυχολογικών μεταβλητών στη ζήτηση τσιγάρων ως προς ένα σύνολο δημογραφικών και κοινωνικοοικονομικών συμμεταβλητών. Η έρευνα βασίζεται σε πρωτογενή διαστρωματικά δεδομένα, των οποίων η συλλογή πραγματοποιήθηκε μέσω ερωτηματολογίων. Επειδή η μεταβλητή που περιγράφει την κατανάλωση τσιγάρων είναι οριακά περιορισμένη σε ότι αφορά το εύρος της, η οικονομετρική ανάλυση χρησιμοποίησε μοντέλα των οριακών εξαρτημένων μεταβλητών. Αρχικά εκτιμήθηκε ένα ordered probit μοντέλο με μεροληψία επιλογής δείγματος, όπου η τιμή του συντελεστή συσχέτισης δε απέρριψε τη μηδενική υπόθεση για ανεξαρτησία των όρων λάθους στα δύο στάδια και επιπλέον το υπό δείγμα των καπνιστών αποτελεί ένα τυχαίο ανεξάρτητο δείγμα. Στη συνέχεια εκτιμήθηκε ένα μοντέλο δύο τμημάτων(βασισμένο στο μοντέλο Cragg) και ένα μοντέλο Tobit, στα οποία δόθηκαν οι κατάλληλες προσεγγίσεις και έγιναν οι απαραίτητοι μετασχηματισμοί για να διορθωθεί η μη κανονικότητα στην κατανομή του όρου λάθους και η ύπαρξη ετεροσκεδαστικότητας. Η εφαρμογή του LR Test κατέληξε στο ότι καταλληλότερο μοντέλο για την εκτίμηση της ζήτησης τσιγάρων είναι το μοντέλο δύο τμημάτων. Σύμφωνα με τα αποτελέσματα που προέκυψαν, τα μέτρα περιορισμού του καπνίσματος και οι ψυχολογικοί παράγοντες προσδιορίζουν τη συμπεριφορά ως προς το κάπνισμα και καθορίζουν τη ζήτηση τσιγάρων
description: This PhD thesis addresses the impact of antismoking policies and psychosocial factors on cigarette demand, controlling for various demographic and socioeconomic variables. The research is based on primary cross section data collected via a formal questionnaire. As the cigarette consumption variable is a limited nature(non smokers report zero daily consumption), corresponding econometric methods had to be adapted. First, the empirical analysis estimates an ordered probit model employed to the whole sample of respondents, and estimates an ordered probit model employed to the whole sample of respondents, and corrects for selectivity bias. The t-value of the selectivity coefficient indicates that there is not selectivity bias for the smoking level, hence the sub-sample of smokers comprises a random and independent sample. Second, a two-part model(based of the model introduced by Cragg) and a Tobit model both adjusted for non-normality and heteroscedasticity of the error terms are adopted to describe cigarette demand. The application of a LR test turns out that the two-part model is the suitable approach for interpreting smoking participation and cigarette consumption. The estimations indicate that antismoking policies and psychosocial factors influence significantly smoking behaviour and comprise the main determinants of cigarette demand

description: The COVID-19 crisis is profoundly influencing the global economic framework due to restrictive measures adopted by governments worldwide. Finding real-time data to correctly quantify this impact is very significant but not as straightforward. Nevertheless, an analysis of the power demand profiles provides insight into the overall economic trends. To accurately assess the change in energy consumption patterns, in this work we employ a multi-layer feed-forward neural network that calculates an estimation of the aggregated power demand in the north of Italy, (i.e, in one of the European areas that were most affected by the pandemics) in the absence of the COVID-19 emergency. After assessing the forecasting model reliability, we compare the estimation with the ground truth data to quantify the variation in power consumption. Moreover, we correlate this variation with the change in mobility behaviors during the lockdown period by employing the Google mobility report data. From this unexpected and unprecedented situation, we obtain some intuition regarding the power system macro-structure and its relation with the overall people's mobility.

description: Using the mechanism of spontaneous symmetry breaking of scale invariance obtained from the dynamics of maximal rank field strengths, it is possible to spontaneously generate confining behavior. Introducing a dilaton field, the study of non trivial confining and de-confining transitions appears possible. This is manifest in two ways at least: One can consider bags which contain an unconfined phase in the internal region and a confined phase outside and also one obtains a simple model for deconfinement at high Temperature from the finite Temperature dynamics of the dilaton field.

Year: 2015

description: The entity Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS) was initially proposed in 1998 (Swedo, et al. 1998). The formal diagnosis required that the affected individual meet five specific criteria: prepubertal onset, obsessive compulsive disorder (OCD) and/or a tic disorder, the dramatic sudden explosive onset of symptoms, a relapsing and remitting course of symptoms that are temporally associated with Group A beta-hemolytic streptococcal (GABHS) infection, and the presence of other neuropsychiatric abnormalities (hyperactivity, emotional lability, anxiety, or piano-playing choreiform movements). Since that original report, the PANDAS hypothesis has remained controversial based on both clinical grounds and the failure to confirm a definitive immune process. This editorial was written in response to: Helm CE, Blackwood RA.

description: The objective of this thesis is the design and developemnt of bidding mechanisms for intelligent software agents that participate in different types of online auctions. In the auction environment, agents try to maximize their revenue, operating in a comparative manner against their rivals. Each agent may represent one or more clients and must make several inter-related decisions in order to obtain the best possible profit. For example, it must decide which is the most profitable auction, when to bid in that auction, as well as what the best price of the submitted bid should be. One important aspect of an agent is its ability to predict the closing price of an auction. This is especially useful for the calculation of the most profitable auction and the deployment of efficient bidding mechanisms based on the prediction of the closing price. Within the context of this dissertation several bidding mechanism have been developed. These take into account historical data produced in the auction environment. Specifically, two types of historical data are taken into consideration : a)intermediate data produced while the auction is still in progress and b)data from past auctions. We have developed two classes of forecasting techniques for each one of the aforementioned data types. These are known as a)short-term and b)long-term forecasting, respectively. Different auction types have been studied and different bidding mechanisms have been developed for each one of them. All mechanisms implement some form of price forecasting based on historical data.

description: The dynamics of large systems of coupled oscillators is a subject of increasing importance with prominent applications in several areas such as physics and biology. The Kuramoto model, where a set of oscillators move around a circle representing their phases, is a paradigm in this field, exhibiting a continuous transition between disordered and synchronous motion. Reinterpreting the oscillators as rotating unit vectors, the model was extended to allow vectors to move on the surface of D-dimensional spheres, with $D=2$ corresponding to the original model. It was shown that the transition to synchronous dynamics was discontinuous for odd D, raising a lot of interest. Inspired by results in 2D, Ott et al proposed an ansatz for density function describing the oscillators and derived equations for the ansatz parameters, effectively reducing the dimensionality of the system. Here we take a different approach for the 3D system and construct an ansatz based on spherical harmonics decomposition of the distribution function. Our result differs significantly from that proposed in Ott's work and leads to similar but simpler equations determining the dynamics of the order parameter. We derive the phase diagram of equilibrium solutions for several distributions of natural frequencies and find excellent agreement with simulations. We also compare the dynamics of the order parameter with numerical simulations and with the previously derived equations, finding good agreement in all cases. We believe our approach can be generalized to higher dimensions and help to achieve complexity reduction in other systems of equations.

Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections (PANDAS): Experience at a Tertiary Referral Center
Creators: name: Helm, Caitlin E.

Year: 2015

description: Background: Pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS) is an autoimmune disorder presenting with obsessive compulsive disorder and/or tics. Like Sydenham’s chorea, its presumed pathogenesis consists of autoantibodies cross-reacting with neurons in response to a group A beta-hemolytic streptococcal infection (GASI). There are currently no diagnostic laboratory findings and management ranges from antibiotic prophylaxis to intravenous immunoglobulin to plasmapheresis. The diagnosis remains controversial, resulting in inconsistent referrals and significant patient anxiety. Methods: A retrospective study was performed on all patients referred to the Pediatric Infectious Disease Division with a pre-referral diagnosis of PANDAS. Patients were analyzed by demographics, medical history, co-morbidities, symptoms, prior treatment, laboratory tests, management strategies, and treatment outcomes. Results: From 2003 to 2013, there were 21 patients with a pre-referral diagnosis of PANDAS. Only five met the diagnostic criteria. No patient at referral had an objective scale to monitor symptoms. Eight referrals had a major psychiatric disorder, and none fulfilled diagnostic criteria (p<0.01). Discussion: The majority of the patients referred with a pre-diagnosis of PANDAS do not fulfill diagnostic criteria nor do they have objective criteria for symptom monitoring. Major psychiatric disorders do not seem to be associated with PANDAS, and better physician education may prevent misdiagnoses. Multidisciplinary management is recommended.

description: Monolayer transition metal dichalcogenides $MX_2$ ($M$ = Mo,W and $X$ = Te, Se, S) in 1T' structure were predicted to be quantum spin Hall insulators based on first-principles calculations, which were quickly confirmed by multiple experimental groups. For a better understanding of their properties, in particular their responses to external fields, we construct a realistic four-band tight-binding (TB) model by combining the symmetry analysis and first-principles calculations. Our TB model respects all the symmetries and can accurately reproduce the band structure in a large energy window from -0.3 eV to 0.8 eV. With the inclusion of spin-orbital coupling (SOC), our TB model can characterize the nontrivial topology and the corresponding edge states. Our TB model can also capture the anisotropic strain effects on the band structure and the strain-induced metal-insulator transition. Moreover, we found that although $MX_2$ share the same crystal structures and have the same crystal symmetries, while the orbital composition of states around the Fermi level are qualitatively different and their lower-energy properties cannot fully described by a single k $\cdot$ p model. Thus, we construct two different types of k $\cdot$ p model for $M$S$_2$,$M$Se$_2$ and $M$Te$_2$, respectively. Benefiting from the high accuracy and simplicity, our TB and k $\cdot$ p models can serve as a solid and concrete starting point for future studies of transport, superconductivity, strong correlation effects and twistronics in 1T'-transition metal dichalcogenides.
Restless Legs Syndrome: Would You Like That with Movements or Without?

description: The restless legs syndrome (RLS) is a common sensorimotor condition that often results in discomfort and sleep disturbance. Diagnosis of RLS is entirely clinical and based upon a patient’s description of subjective symptoms, and thus when considering RLS diagnosis non-specificity is a real problem. RLS is associated with periodic limb movements during sleep (PLMS) in up to 90% of RLS sufferers; however, their presence is neither sufficient nor necessary for the diagnosis of RLS. The disease RLS and the motor phenomenon of PLMS share similarities in various areas, which include pathophysiology, pharmacology, genetics, and epidemiology. The purpose of this opinion piece is to outline the many similarities between RLS and PLMS in order to make an argument for the inclusion of PLMS as a supplementary diagnostic criterion of RLS, termed electro-clinical RLS, which would consist of the current clinical RLS diagnosis plus PLMS. This additional criterion could be used in cases where diagnosis is unclear to increase specificity or in research projects where proper diagnosis is desired at the investigational level.

description: A model describing amplification and quantum statistics of the exciton polaritons with k=0 in a non-resonantly excited semiconductor quantum well embedded in a microcavity is presented. Exploiting the bottleneck effect for exciton polaritons, it is assumed that the polaritons with k different from 0 act as a reservoir. The time evolution of the k=0 polaritons is described by a master equation, in which two- and one-polariton transitions between the mode with k=0 and the reservoir are accounted for. The k=0 mode exhibits a threshold depending on the material parameters and on the injected exciton density. Below threshold the quantum statistics of the emission is characteristic of an incoherent process, while above threshold it approaches that of a laser.

description: We reliably extend the stellar mass-size relation over $0.2\leq z \leq2$ to low stellar mass galaxies by combining the depth of Hubble Frontier Fields (HFF) with the large volume covered by CANDELS. Galaxies are simultaneously modelled in multiple bands using the tools developed by the MegaMorph project, allowing robust size (i.e., half-light radius) estimates even for small, faint, and high redshift galaxies. We show that above 10$^7$M$_\odot$, star-forming galaxies are well represented by a single power law on the mass-size plane over our entire redshift range. Conversely, the stellar mass-size relation is steep for quiescent galaxies with stellar masses $\geq 10^{10.3}$M$_\odot$ and flattens at lower masses, regardless of whether quiescence is selected based on star-formation activity, rest-frame colours, or structural characteristics. This flattening occurs at sizes of $\sim1$kpc at $z\leq1$. As a result, a double power law is preferred for the stellar mass-size relation of quiescent galaxies, at least above 10$^7$M$_\odot$. We find no strong redshift dependence in the slope of the relation of star-forming galaxies as well as of high mass quiescent galaxies. We also show that star-forming galaxies with stellar masses $\geq$10$^{9.5}$M$_\odot$ and quiescent galaxies with stellar masses $\geq10^{10.3}$M$_\odot$ have undergone significant size growth since $z\sim2$, as expected; however, low mass galaxies have not. Finally, we supplement our data with predominantly quiescent dwarf galaxies from the core of the Fornax cluster, showing that the stellar mass-size relation is continuous below 10$^7$M$_\odot$, but a more complicated functional form is necessary to describe the relation.

Στο εργαστήριο χρησιμοποιληθηκε εξομοιωμένο σπογγώδες οστούν και δακτύλιος μέτρησης συμπίεσης. Η βίδα Α05.5/3mm πέτυχε διπλάσια συμπιεστική δύναμη της βίδας Α02mm. Οι βίδες mini-Acutrak και Herbert-Whipple άσκησαν 72% της συμπίεσης της μεγάλης βίδας Α0 έχοντας περίπου την μισή διάμετρο αυτής. Τα μικρά υλικά χρησιμοποιήθηκαν σε δύο ομάδες ασθενών, ομάδα Α(βίδα mini Acutrak) 34 περιπτώσεις και ομάδα Β(βίδα A02mm) 26 περιπτώσεις. Πώρωση συνέβη κατά 94%/4.8 μήνες(ομάδα Α) και κατά 85%/4 μήνες(ομάδα Β). Τα ποσοστά πώρωσης της ομάδας Α ήταν ίσα με τα υψηλότερα στην διεθνή βιβλιογραφία όπου χρησιμοποιήθηκαν τα μεγαλύτερα υλικά γεγονός που επιβεβαίωσε την υπόθεση της διατριβής.

description: The hypothesized that if relative stability only is adequate for the fixation of scaphoid non-union, mini-implants should achieve similar union rates and union speed when compared with their larger counterparts. We measured the compression generated by three mini implants, the A02.0mm mini screw, the Herbert-Whipple and the mini-Acutrak screw. We compared these with a larger screw, the A05.5/3.0mm. In the laboratory, we used simulated cancellous bone and a load cell to quantify the fixation capabilities. The A05.5/3mm screw achieved a compressive capacity twice that of the 2.0mm cortical screw and higher than the Mini-Acutrak and Herbert-Whipple screws. These screws gained 72% of compression of the Ao screw despite of having a diameter almost hafl its size. Two patient groups were treated with mini bone screws for scaphoid non-union. Group A(34 cases) with the mini-Acutrak screw and Group B926 cases) with thw A02mm screw. Union was achieved in 94% of cases in Group A were equal to the best results reported in the existing literature with the use of larger(standard) implants thus confirming the hypothesis of the dissertation. The size of implant did not greatly infuence the outcome of scaphoid non-union fixation, which is likely to be influenced by biological factors. The use of mini implants in combination with the principles of A0/ASIF was successful and safe and the author has no hesitation to recommend these implants in the daily clinical practice

description: We present a detailed chemical abundance analysis of HE 1300+0157, a subgiant with [Fe/H]=-3.9. From a high-resolution, high-S/N Subaru/HDS spectrum we find the star to be enriched in C ([C/Fe]_1D ~ +1.4) and O ([O/Fe]_1D ~ +1.8). With the exception of these species, HE 1300+0157 exhibits an elemental abundance pattern similar to that found in many other very and extremely metal-poor stars. The Li abundance is lower than the Spite-plateau value, in agreement with expectation for its evolutionary status. Of particular interest, no neutron-capture elements are detected in HE 1300+0157. This type of abundance pattern has been found by recent studies in several other metal-poor giants. We suggest that HE 1300+0157 is an unevolved example of this group of stars, which exhibit high C abundances together with low (or absent) abundances of neutron-capture elements. Several potential enrichment scenarios are presented. The low neutron-capture elements, including Sr, Ba, and Pb, suggests that the carbon excess observed in HE 1300+0157 is not due to mass transfer across a binary system. Such a scenario is applied to carbon-rich objects with excesses of s-process elements. The normal observed Li abundance supports this interpretation. Most likely, the high levels of C and O were produced prior to the birth of this star. It remains unclear whether a single hypernova is responsible for its overall chemical pattern, or whether one requires a superposition of yields from a massive Population III object and a normal Type II SN. These scenarios provide important information on the C production in the early Universe, and on the formation of C-rich stars in the early Galaxy.

description: This is a laboratory study that compares the activity between the anterior and the posterior part of the growth cartilage of the distal femoral epiphysis of a fractured femur of laboratory rats as a result of union with angular deformity using biological parameters. The growth plate and specifically the proliferative zone of those two areas was also histologically studied and contrasted. Fifty-six white laboratory Wistar male rats three weeks old were used. Fracture of the right femoral diaphysis was surgically produced and left free to obtain anterior angulation. The material that was used consisted of the growth plate of the distal femoral epiphysis of all the fractured femurs after sacrifice at 48,96 or 168 hours after the fracture. The conciseness in DNA and protein of the anterior and the posterior part of the growth plate were contrasted. There was a statistically significant rise in DNA/mg as well as in protein/mg at the side of the growth plate that is adjacent to the concave side of the fracture. To conclude, the biological and histological results in the examined laboratory rats show increased activity of the side of the growth plate that is adjacent to the concave side of the fracture as compared to the other side as means of correcting the angulation

description: Natural language processing methods have been applied in a variety of music studies, drawing the connection between music and language. In this paper, we expand those approaches by investigating \textit{chord embeddings}, which we apply in two case studies to address two key questions: (1) what musical information do chord embeddings capture?; and (2) how might musical applications benefit from them? In our analysis, we show that they capture similarities between chords that adhere to important relationships described in music theory. In the first case study, we demonstrate that using chord embeddings in a next chord prediction task yields predictions that more closely match those by experienced musicians. In the second case study, we show the potential benefits of using the representations in tasks related to musical stylometrics.

description: We extend the former matrix rearrangement approach of the entangling power to the general cases, without the requirement of the same dimensions of the subsystems. The entangling power of a unitary operator is completely determined by its realignment and partial transposition. As applications, we calculate the entangling power for the Ising interaction and the isotropic Heisenberg interaction in the mixed qudit system.

Pain perception in chronic pain patients : a signal detection analysis
Creators: name: Mahon, Mary L.
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this investigation was to examine the supposition that chronic pain patients (CPPs) have altered pain perception. Two models were examined that led to opposing predictions as to how CPPs would respond to painful stimuli (i.e., the hypervigilance and adaptation-level models). Both predictions have been supported by past research but because of methodological variation and the type of pain disorder studied, it has remained unclear under what circumstances the predictions of these two models may be met. The responses of pain patients to painful stimuli have been found to vary for patients-with different clinical presentations (i.e. those with and without medically incongruent signs and symptoms). Therefore, the present investigation sought to compare the responses to radiant heat stimuli of sixty CPPs (thirty with and thirty without a medically incongruent pain presentation) to thirty age and sex matched normal control subjects (i.e., pain-tree individuals). Signal detection theory methodology was used in order to separately evaluate sensory sensitivity and the response bias to report sensations as painful. In addition, cognitive and affective factors were assessed in order to identity potential psychological correlates of altered pain perception. The results of this study indicated that the presence of a medically incongruent pain presentation distinguished patients on their subjective report of disability and to a lesser extent cognitive appraisal and affective distress regarding their pain condition. They did not differ in their responses to painful stimuli. In a post hoc analysis where CPPs were classified into 'organic' and 'functional’ diagnostic groups, significant differences in pain threshold and the response bias to report pain were found. Patients classified as 'organic' had significantly higher pain thresholds compared to normal control subjects and patients classified as 'functional'. Differences in pain threshold were primarily represented by the response' bias to report sensations as painful rather than sensory sensitivity to the stimuli. The 'functional' group had a slightly lower pain threshold than the normal control group but this difference was not significant. The results are discussed in light of the two models of pain perception. The two methods used to classify pain patients are discussed according to their orthogonal characteristics on sensory, cognitive, and affective components.

description: Background: Corticobasal syndrome (CBS) is a complex neurodegenerative disorder associated with parkinsonism and alien limb syndrome. Dressing and ideomotor apraxia were reportedly responsive to amantadine. Case Report: A 79‐year‐old female was referred for evaluation of right hemiparesis. Neurological examination showed dementia, normal ocular movements, mild facial hypomimia, and bradykinesia with right hemiparesis. Nine years later, she developed alien limb syndrome and was diagnosed with CBS. After failure to respond to several medications, alien limb syndrome markedly improved with amantadine. Discussion: To the best of our knowledge, this is the first report of a consistent response of severe, forced dystonic alien limb syndrome to amantadine in a patient with CBS.

description: The Majorana nature of neutrinos may only be experimentally verified via lepton-number violating processes involving charged leptons. We explore the $ΔL=2$ like-sign dilepton production at hadron colliders to search for signals of Majorana neutrinos. We find significant sensitivity for resonant production of a Majorana neutrino in the mass range of 10-80 GeV at the current run of the Tevatron with 2 fb$^{-1}$ integrated luminosity, and in the range of 10-400 GeV at the LHC with 100 fb$^{-1}$.

description: We consider non-compact branes in topological string theories on a class of Calabi-Yau spaces including the resolved conifold and its mirror. We compute the amplitudes of the insertion of non-compact Lagrangian branes in the A-model on the resolved conifold in the context of the topological vertex as well as the melting crystal picture. They all agree with each other and also agree with the results from Chern-Simons theory, supporting the large N duality. We find that they obey the Schrödinger equation confirming the wavefunction behavior of the amplitudes. We also compute the amplitudes of the non-compact B-branes in the DV matrix model which arises as a B-model open string field theory on the mirror manifold of the deformed conifold. We take the large N duality to consider the B-model on the mirror of the resolved conifold and confirm the wave function behavior of this amplitude. We find appropriate descriptions of non-compact branes in each model, which give complete agreements among those amplitudes and clarify the salient features including the role of symmetries toward these agreements.

description: In this paper we consider a class of generalizations of Schnabl's solution of open bosonic string field theory obtained by replacing the wedge state by an arbitrary combination of wedge states. We find that under a few modest conditions such generalizations give a sensible deformation of Schnabl's solution for the closed string vacuum--in particular, we can compute their energies and show that they reproduce the value predicted by Sen's conjecture. Though these solutions are apparently gauge equivalent, they are not in general related by midpoint-preserving reparameterizations.

Convergence of Griddy Gibbs Sampling and other perturbed Markov chains

description: The Griddy Gibbs sampling was proposed by Ritter and Tanner (1992) as a computationally efficient approximation of the well-known Gibbs sampling method. The algorithm is simple and effective and has been used successfully to address problems in various fields of applied science. However, the approximate nature of the algorithm has prevented it from being widely used: the Markov chains generated by the Griddy Gibbs sampling method are not reversible in general, so the existence and uniqueness of its invariant measure is not guaranteed. Even when such an invariant measure uniquely exists, there was no estimate of the distance between it and the probability distribution of interest, hence no means to ensure the validity of the algorithm as a means to sample from the true distribution. In this paper, we show, subject to some fairly natural conditions, that the Griddy Gibbs method has a unique, invariant measure. Moreover, we provide $L^p$ estimates on the distance between this invariant measure and the corresponding measure obtained from Gibbs sampling. These results provide a theoretical foundation for the use of the Griddy Gibbs sampling method. We also address a more general result about the sensitivity of invariant measures under small perturbations on the transition probability. That is, if we replace the transition probability $P$ of any Monte Carlo Markov chain by another transition probability $Q$ where $Q$ is close to $P$, we can still estimate the distance between the two invariant measures. The distinguishing feature between our approach and previous work on convergence of perturbed Markov chain is that by considering the invariant measures as fixed points of linear operators on function spaces, we don't need to impose any further conditions on the rate of convergence of the Markov chain.

Year: 2015

description: Background: Tremor and headache are two of the most prevalent neurological conditions. This review addresses possible associations between various types of tremor and headache, and provides a differential diagnosis for patients presenting with both tremor and headache. Methods: Data were identified by searching MEDLINE in February 2015, with the terms “tremor” and terms representing the primary headache syndromes. Results: Evidence for an association between migraine and essential tremor is conflicting. Other primary headaches are not associated with tremor. Conditions that may present with both tremor and headache include cervical dystonia, infectious diseases, hydrocephalus, spontaneous cerebrospinal fluid leaks, space-occupying lesions, and metabolic disease. Furthermore, both can be seen as a side effect of medication and in the use of recreational drugs. Discussion: No clear association between primary headaches and tremor has been found. Many conditions may feature both headache and tremor, but rarely as core clinical symptoms at presentation.
