description: SrTiO$_3$-based two-dimensional electron gases (2DEGs) can be formed through the deposition of epitaxial oxides like LaAlO$_3$ or of reactive metals such as Al. Such 2DEGs possess a finite Rashba spin-orbit coupling that has recently been harnessed to interconvert charge and spin currents through the direct and inverse Edelstein and spin Hall effects. Here we compare the formation and properties of 2DEGs generated in SrTiO$_3$ by the growth of Al, Ta and Y ultrathin films by magnetron sputtering. By combining in situ and ex situ X-ray photoelectron spectroscopy (XPS) we gain insight into the reduction of the SrTiO$_3$ and the appearance of Ti$^{3+}$ states associated with 2DEG formation, its reoxidation by exposure to the air, and the transformation of the metal into its binary oxides. We extract the carrier densities through magnetotransport and compare them with the XPS data. Finally, working with samples covered by an extra layer of NiFe, we perform spin-pumping ferromagnetic resonance experiments and investigate spin-charge conversion as a function of gate voltage. We identify trends in the data across the different sample systems and discuss them as a function of the carrier density and the transparency of the metal oxide tunnel barrier.

description: Given a family of real probability measures $(μ_t)_{t\geq 0}$ increasing in convex order (a peacock) we describe a systematic method to create a martingale exactly fitting the marginals at any time. The key object for our approach is the obstructed shadow of a measure in a peacock, a generalization of the (obstructed) shadow introduced in \cite{BeJu16,NuStTa17}. As input data we take an increasing family of measures $(ν^α)_{α\in [0,1]}$ with $ν^α(\mathbb{R})=α$ that are submeasures of $μ_0$, called a parametrization of $μ_0$. Then, for any $α$ we define an evolution $(η^α_t)_{t\geq 0}$ of the measure $ν^α=η^α_0$ across our peacock by setting $η^α_t$ equal to the obstructed shadow of $ν^α$ in $(μ_s)_{s \in [0,t]}$. We identify conditions on the parametrization $(ν^α)_{α\in [0,1]}$ such that this construction leads to a unique martingale measure $π$, the shadow martingale, without any assumptions on the peacock. In the case of the left-curtain parametrization $(ν_{\text{lc}}^α)_{α\in [0,1]}$ we identify the shadow martingale as the unique solution to a continuous-time version of the martingale optimal transport problem. Furthermore, our method enriches the knowledge on the Predictable Representation Property (PRP) since any shadow martingale comes with a canonical Choquet representation in extremal Markov martingales.

Neuroimaging of Essential Tremor: What is the Evidence for Cerebellar Involvement?

Publisher: name: Tremor and Other Hyperkinetic Movements
Year: 2012

description: Background: Clinical observations and electrophysiological studies have provided initial evidence for the involvement of the cerebellum in essential tremor (ET), the most frequent hyperkinetic disorder. Recently, this hypothesis has been reinvigorated by post-mortem studies that demonstrated a number of pathological changes in the cerebellum of ET patients compared with age-matched healthy controls. Advanced neuroimaging techniques have also made it possible to detect in vivo which cerebellar abnormalities are present in ET patients and to reveal the core mechanisms implicated in the development of motor and cognitive symptoms in ET. Objective: We discuss the neuroimaging research investigating the brain structure and function of ET patients relative to healthy controls. In particular, we review 1) structural neuroimaging experiments assessing the density/volume of cortical/subcortical regions and the integrity of the white-matter fibers connecting them; 2) functional studies exploring brain responses during motor/cognitive tasks and the function of specific neurotransmitters/metabolites within cortical–cerebellar circuits. Methods: A search in PubMed was conducted to identify the relevant literature. Discussion: Current neuroimaging research provides converging evidence for the role of the cerebellum in the pathophysiology of ET, although some inconsistencies exist, particularly in structural studies. These discrepancies may depend on the high clinical heterogeneity of ET and on differences among the experimental methods used across studies. Further investigations are needed to disentangle the relationships between specific ET phenotypes and the underlying patterns of neural abnormalities.

description: Background: Although tetrabenazine, a drug that depletes presynaptic dopamine by inhibiting vesicular monoamine transporter 2 (VMAT2), was approved by the U.S. Food and Drug Administration in 2008 for the treatment of chorea associated with Huntington’s disease (HD), there is a paucity of data on its long‐term efficacy and safety. Methods: Approximately 2,000 patients with a variety of hyperkinetic movement disorders had been treated with open‐label tetrabenazine at the Movement Disorders Clinic, Baylor College of Medicine, since 1979. Tetrabenazine was usually started at 12.5 mg/day, and the dosage was gradually increased (up to 300 mg/day). Responses were rated by the investigator 1–5, with 1 = marked chorea reduction, excellent improvement in function; 2 = moderate chorea reduction, very good improvement in function; 3 = fair chorea improvement, only mild improvement in function; 4 = poor or no response for chorea and function; and 5 = worsening chorea, some functional deterioration. Efficacy and safety were analyzed retrospectively. Results: By 2004, 98 HD chorea patients had received tetrabenazine for a mean of 3.1 years (range ≤1–11.4 years). Of those with valid ratings, 75% had either marked or very good responses (rating 1 or 2) at their optimal dosages. The most common adverse events occurring in ≥5% of the patients were somnolence (39%), insomnia (33%), depression (31%), accidental injury (26%), and dysphagia (19%). Efficacy and safety were comparable to results for non‐HD chorea patients. Discussion: Tetrabenazine treatment was associated with long‐term improvement in chorea. Adverse event rates were comparable to those reported from controlled trials.

description: Variational Hybrid Quantum Classical Algorithms (VHQCAs) are a class of quantum algorithms intended to run on noisy intermediate-scale quantum (NISQ) devices. These algorithms employ a parameterized quantum circuit (ansatz) and a quantum-classical feedback loop. A classical device is used to optimize the parameters in order to minimize a cost function that can be computed far more efficiently on a quantum device. The cost function is constructed such that finding the ansatz parameters that minimize its value, solves some problem of interest. We focus specifically on the Variational Quantum Linear Solver (VQLS), and examine the effect of several gradient-free and gradient-based classical optimizers on performance. We focus on both the average rate of convergence of the classical optimizers studied, as well as the distribution of their average termination cost values, and how these are affected by noise. Our work demonstrates that realistic noise levels on NISQ devices present a challenge to the optimization process. All classical optimizers appear to be very negatively affected by the presence of realistic noise. If noise levels are significantly improved, there may be a good reason for preferring gradient-based methods in the future, which performed better than the gradient-free methods with the only shot-noise present. The gradient-free optimizers, Simultaneous Perturbation Stochastic Approximation (SPSA) and Powell's method, and the gradient-based optimizers, AMSGrad and BFGS performed the best in the noisy simulation, and appear to be less affected by noise than the rest of the methods. SPSA appears to be the best performing method. COBYLA, Nelder-Mead and Conjugate-Gradient methods appear to be the most heavily affected by noise, with even slight noise levels significantly impacting their performance.

description: One of the key objectives of the FarFish project is: "To advance knowledge and collate data related to biological characteristics of the main fish stocks in selected fisheries outside EU waters that are important for the EU fleet, and to evaluate the relevance and applicability of appropriate stock assessment methods for these fisheries." In this context, the review and evaluation of stock assessment models used in the different Case Studies and the status of the stocks is one of the primary objectives of the project. The FarFish project has therefore published this report, which contains a review the stock assessment carried out for the target species in each of the case study areas.
Star formation in Perseus. IV. Mass dependent evolution of dense cores

name: Fuller, Gary
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In our SCUBA survey of Perseus, we find that the fraction of protostellar cores increases towards higher masses and the most massive cores are all protostellar. In this paper we consider the possible explanations of this apparent mass dependence in the evolutionary status of these cores, and the implications for protostellar evolution and the mapping of the embedded core mass function (CMF) onto the stellar IMF. We consider the following potential causes: dust temperature; selection effects in the submillimetre and in the mid-infrared observations used for pre/protostellar classification; confusion and multiplicity; transient cores; and varying evolutionary timescales. We develop Core Mass Evolution Diagrams (CMEDs) to investigate how the mass evolution of individual cores maps onto the observed CMF. Two physical mechanisms -- short timescales for the evolution of massive cores, and continuing accumulation of mass onto protostellar cores -- best explain the relative excess of protostars in high mass cores and the rarity of massive starless cores. In addition, confusion both increases the likelihood that a protostar is identified within a core, and increases mass assigned to a core. The observed pre/protostellar mass distributions are consistent with faster evolution and a shorter lifetime for higher-mass prestellar cores. We rule out longer timescales for higher-mass prestellar cores. The differences in the prestellar and protostellar mass distributions imply that the prestellar CMF (and possibly the combined pre+protostellar CMF) should be steeper than the IMF. A steeper prestellar CMF can be reconciled with the observed similarity of the CMF and the IMF in some regions if a second opposing effect is present, such as the fragmentation of massive cores into multiple systems.

description: Background: To determine whether botulinum toxin treatment history affected the outcomes of a study comparing the safety and efficacy of incobotulinumtoxinA with placebo in subjects with cervical dystonia (CD). Methods: This was a prospective, double‐blind, randomized, placebo‐controlled, multicenter trial in botulinum toxin‐treated or toxin‐naïve CD subjects. Subjects received a fixed dose of either 120 U or 240 U of incobotulinumtoxinA or placebo. The primary outcome measure was change from baseline to Week 4 in the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total score. Treatment‐emergent adverse events (TEAEs) were also evaluated. This report represents a subgroup analysis of botulinum toxin‐treated or toxin‐naïve subjects. Results: Participants (N = 233; 38.6% toxin‐naïve) had a mean age of 52.8 years. IncobotulinumtoxinA significantly improved TWSTRS total scores from baseline to Week 4 in both dose groups versus placebo, and the improvement persisted through the end of the study (≤20 weeks). Both the previously toxin‐treated and toxin‐naïve subjects demonstrated significant improvements in TWSTRS total scores at Week 4 compared to baseline. The most frequent TEAEs in the incobotulinumtoxinA groups were dysphagia, neck pain, and muscular weakness, which were generally mild. TEAEs were more common in the 240 U group and toxin‐naïve subjects. Discussion: Overall, incobotulinumtoxinA was safe and effective in CD, regardless of toxin therapy history. A lower starting dose may be better tolerated among toxin‐naïve subjects without sacrificing efficacy.

The effect of major stock downturns on executive stock option contracts
Creators: name: Saly, Jane P.
Publisher: name: University of British Columbia
Year: 2011

description: This dissertation analyzes the effect of a stock market downturn on executive compensation plans which include stock option contracts. A model is developed to determine sufficient conditions for which the optimal compensation contract exhibits characteristics of a fixed salary plus stock option. If a publicly known shift in the distribution of firm value occurs after contracting and before the agent takes his action, then it can be shown to be in the principal's interest to renegotiate the agent's contract. The resulting contract is again a fixed salary plus stock options with lower exercise prices than in the original contract. It is assumed that the shift in the distribution of firm value is a low probability event that is not contracted upon. To determine whether or not it is optimal to contract on a low probability event the set of original contract and rengotiated contract is compared to a contract that is complete with respect to the event. Benefits to complete contracting exist if the agent commits to stay after information about the event becomes available. However, if the agent can leave at any time, the principal may prefer, initially, not to contract on low probability events and simply renegotiate the contract if a low probability event occurs. Renegotiation can take the form of lowering the exercise price of outstanding stock options or adding a layer of options with a lower exercise price than existing outstanding options. Nonparametric tests on stock option grants in 1985 through 1988 indicate that the size of grants in 1987 and 1988 is significantly larger than in 1985 and 1986. These results support the prediction that stock options outstanding in 1987 were renegotiated following the stock crash in October 1987.

description: The random XORSAT problem deals with large random linear systems of Boolean variables. The difficulty of such problems is controlled by the ratio of number of equations to number of variables. It is known that in some range of values of this parameter, the space of solutions breaks into many disconnected clusters. Here we study precisely the corresponding geometrical organization. In particular, the distribution of distances between these clusters is computed by the cavity method. This allows to study the `x-satisfiability' threshold, the critical density of equations where there exist two solutions at a given distance.

description: The local equilibrium approach previously developed by the Authors [J. Mabillard and P. Gaspard, J. Stat. Mech. (2020) 103203] for matter with broken symmetries is applied to crystalline solids. The macroscopic hydrodynamics of crystals and their local thermodynamic and transport properties are deduced from the microscopic Hamiltonian dynamics. In particular, the Green-Kubo formulas are obtained for all the transport coefficients. The eight hydrodynamic modes and their dispersion relation are studied for general and cubic crystals. In the same twenty crystallographic classes as those compatible with piezoelectricity, cross effects coupling transport between linear momentum and heat or crystalline order are shown to split the degeneracy of damping rates for modes propagating in opposite generic directions.

description: The focusing of electric current by a single \textit{p-n} junction in graphene is predicted. We show that precise focusing can be achieved by fine-tuning the densities of carriers on the n- and p-sides of the junction to equal values, whereas the current distribution in junctions with different densities resembles caustics in optics. This finding can be utilized in the engineering of electronic lenses and focused beam-splitters using gate-controlled \textit{n-p-n} junctions in graphene-based transistors.

description: The adatom arrays on surfaces offer an ideal playground to explore the mechanisms of chemical bonding via changes in the local electronic tunneling spectra. While this information is readily available in hyperspectral scanning tunneling spectroscopy data, its analysis has been considerably impeded by a lack of suitable analytical tools. Here we develop a machine learning based workflow combining supervised feature identification in the spatial domain and un-supervised clustering in the energy domain to reveal the details of structure-dependent changes of the electronic structure in adatom arrays on the Co3Sn2S2 cleaved surface. This approach, in combination with first-principles calculations, provides insight for using artificial neural networks to detect adatoms and classifies each based on their local neighborhood comprised of other adatoms. These structurally classified adatoms are further spectrally deconvolved. The unexpected inhomogeneity of electronic structures among adatoms in similar configurations is unveiled using this method, suggesting there is not a single atomic species of adatoms, but rather multiple types of adatoms on the Co3Sn2S2 surface. This is further supported by a slight contrast difference in the images (or slight size variation) of the topography of the adatoms.

description: Background: We report the interim results from XCiDaBLE: A large prospective, observational "naturalistic" study evaluating Xeomin® (incobotulinumtoxinA) for cervical dystonia or blepharospasm in the United States. Methods: Subjects with CD are followed for 2 treatment cycles and monitored via Interactive Voice/Web Response. Subject-reported scales include the Subject Global Impression-Severity and Improvement; Cervical Dystonia Impact Profile (CDIP-58); and Work Productivity and Quality of Life (QoL) are assessed by means of an employment questionnaire and work history and the SF-12v2. Results: This ongoing study includes 145 subjects with a diagnosis of CD. The majority were female (82.3%) and White (91.0%) and had previously been treated with botulinum toxins (77.2%). There were 106 employed at the time of onset of the disease, but 12.6 years later only 44% were still employed at the time of enrolment into the study and 20% were either receiving or seeking disability benefits. However, only 44% were still employed at the time of recruitment for study participation. The mean total dose/treatment of CD was 225.2 units for the 1st injection. The CDIP-58 total score was significantly improved at four weeks post the first injection compared to baseline (p=<0.0001). Most subjects noted improvement in their global impression assessment. No new or unexpected adverse events occurred. Discussion: The results from these interim analyses confirm previous controlled single-dose studies of incobotulinumtoxinA in terms of efficacy and safety.

description: The GWAC-N is an observation network composed of multi-aperture and multi-field of view robotic optical telescopes. The main instruments are the GWAC-A. Besides, several robotic optical telescopes with narrower field of views provide fast follow-up multi-band capabilities to the GWAC-N. The primary scientific goal of the GWAC-N is to search for the optical counterparts of GRB that will be detected by the SVOM. The GWAC-N performs many other observing tasks including the follow-ups of ToO and both the detection and the monitoring of variable/periodic objects as well as optical transients. To handle all of those scientific cases, we designed 10 observation modes and 175 observation strategies, especially, a joint observation strategy with multiple telescopes of the GWAC-N for the follow-up of GW events. To perform these observations, we thus develop an AOM system in charge of the object management, the dynamic scheduling of the observation plan and its automatic broadcasting to the network management and finally the image management. The AOM combines the individual telescopes into a network and smoothly organizes all the associated operations. The system completely meets the requirements of the GWAC-N on all its science objectives. With its good portability, the AOM is scientifically and technically qualified for other general purposed telescope networks. As the GWAC-N extends and evolves, the AOM will greatly enhance the discovery potential for the GWAC-N. In the first paper of a series of publications, we present the scientific goals of the GWAC-N as well as the hardware, the software and the strategy setup to achieve the scientific objectives. The structure, the technical design, the implementation and performances of the AOM will be also described in details. In the end, we summarize the current status of the GWAC-N and prospect for the development plan in the near future.

description: We calculated the image potentials of single-walled carbon nanotubes of various structures in the condition of field emission with a quantum chemistry method. The image potential of the single-walled carbon nanotubes can be well fitted with the image potential of an ideal metal sphere in a size comparable to an atom. The image potential is not sensitive to both the applied field and the structure of the tube. When the image potential is included, the emission current would be one order larger.

description: We consider a numerical approach for a covariant generalised Navier-Stokes equation on general surfaces and study the influence of varying Gaussian curvature on anomalous vortex-network active turbulence. This regime is characterised by self-assembly of finite-size vortices into linked chains of anti-ferromagnet order, which percolate through the entire surface. The simulation results reveal an alignment of these chains with minimal curvature lines of the surface and indicate a dependency of this turbulence regime on the sign and the gradient in local Gaussian curvature. While these results remain qualitative and their explanations are still incomplete, several of the observed phenomena are in qualitative agreement with experiments on active nematic liquid crystals on toroidal surfaces and contribute to an understanding of the delicate interplay between geometrical properties of the surface and characteristics of the flow field, which has the potential to control active flows on surfaces via gradients in the spatial curvature of the surface.

description: Nel 2023 ricorrono i cinquant’anni dall’uscita di un fondamentale volume di Lucio Gambi, Una geografia per la storia (Einaudi, Torino, 1973), raccolta di contributi del geografo ravennate. Si tratta forse dell’opera più nota di Gambi, in cui egli demolisce una vecchia idea nozionistica della geografia, nella ricerca come nella didattica, fatta di enumerazioni e descrizioni (una Geografia regione depressa, citando il titolo di un suo scritto ricompreso entro la sopraccitata monografia del 1973), e in cui contropropone una sua concezione della materia come disciplina territoriale, critica, focalizzata sull’evoluzione diacronica dei quadri ambientali e delle città, con una forte valenza politica («fare cultura è impegnarsi per la società», scriveva Gambi nella prefazione di quel volume).

Thoughts on Selected Movement Disorders Terminology and a Plea for Clarity
Creators: name: Walker, Ruth Helen
Publisher: name: Tremor and Other Hyperkinetic Movements

description: Description of the phenomenology of movement disorders requires precise and accurate terminology. Many of the terms that have been widely used in the literature are imprecise and open to interpretation. An examination of these terms and the assumptions implicit in their usage is important to improve communication and hence the definition, diagnosis, and treatment of movement disorders. I recommend that the term dyskinesia should be used primarily in the settings of Parkinson's disease and tardive dyskinesia, in which its clinical implications are relatively clear; it should not be used in other situations where a precise description could more usefully facilitate diagnosis and treatment. In general dyskinesia should be used in the singular form. Extrapyramidal is based upon obsolete anatomical concepts, is uninformative, and should be discarded. The term abnormal involuntary movements (AIMs) is similarly vague and uninformative, although is unlikely to be eliminated from the psychiatric literature. Movement disorder neurologists as teachers, clinicians, article reviewers, and journal editors have the responsibility to educate our colleagues regarding appropriate usage and the importance of employing correct descriptors.
