description: In this paper we calculate the non-perturbative Euler-Heisenberg Lagrangian for massless QED in a strong magnetic field $H$, where the breaking of the chiral symmetry is dynamically catalyzed by the external magnetic field via the formation of an electro-positron condensate. This chiral condensate leads to the generation of dynamical parameters that have to be found as solutions of non-perturbative Schwinger-Dyson equations. Since the electron-positron pairing mechanism leading to the breaking of the chiral symmetry is mainly dominated by the contributions from the infrared region of momenta much smaller than $\sqrt{eH}$, the magnetic field introduces a dynamical ultraviolet cutoff in the theory that also enters in the non-perturbative Euler-Heisenberg action. Using this action, we show that the system exhibits a significant paraelectricity in the direction parallel to the magnetic field. The nonperturbative nature of this effect is reflected in the non-analytic dependence of the obtained electric susceptibility on the fine-structure constant. The strong paraelectricity in the field direction is linked to the orientation of the electric dipole moments of the pairs that form the chiral condensate. The large electric susceptibility can be used to detect the realization of the magnetic catalysis of chiral symmetry breaking in physical systems.

description: Background: There is a lack of evidence examining the role of physical therapy (PT) to address movement dysfunction for individuals with essential tremor (ET).

Case Report: A 61-year-old male with ET and prolonged bilateral deep brain stimulation (DBS) completed 14 sessions of outpatient PT that emphasized balance, functional movements, and proximal stability training with an integration of principles of body awareness training and visual motor coordination. Improvements were noted in all outcome measures.

Discussion: This report describes a novel PT approach that offers a promising means of improving functional mobility and balance while decreasing falls risk in patients with ET.

Progressive supranuclear palsy

description: Background: Deep brain stimulation (DBS) for essential tremor (ET) can cause unwanted side effects.

Case Report: A patient with ET underwent unilateral dual-lead thalamic DBS. He later developed parkinsonism with atypical features and was diagnosed with progressive supranuclear palsy. During presentation for a second opinion, stimulation-induced side effects were suspected. Inactivation of DBS resolved atypical features and superimposed idiopathic Parkinson Disease (PD) was diagnosed.

Discussion: This case illustrates the importance of recognizing the possible influence of stimulation-induced side effects and discusses when to utilize dual-lead DBS for ET and the co-occurrence of ET and PD.

description: Background: Tourette syndrome (TS) has been described as peaking in adolescence with subsequent regression. We report patients who were diagnosed with TS during childhood who experienced a latent period (significant reduction in or absence of tics) followed by tic re-emergence in adulthood.

Methods: We performed a retrospective chart review of outpatients over age 21 seen at the Yale neurology clinic between January 2012 and July 2016 who were diagnosed with childhood-onset tics, and who experienced a latent period of greater than 1 year followed by an exacerbation.

Results: Sixteen patients were identified. The mean latent period was 16 years. Ten patients (62.5%) identified an exacerbation trigger, most commonly changes in substance use (five patients). Seven patients (43.8%) reported worsening of tics since childhood. Six patients (37.5%) had received pharmacological intervention for tics as children, and 15 patients (93.8%) as adults. Six of 15 patients (40.0%) had an effective response from those pharmacological intervention(s).

Discussion: Our study demonstrates that the decline in symptoms as patients age may represent temporary improvement. The latent period lasted years in our patients, different from the more rapid waxing and waning in children. A change in substance use was an important trigger. Requests for pharmacological intervention were not necessarily correlated with worsening tic severity.

description: Chorea-Acanthocytosis (ChAc) is a rare hereditary neurological disorder characterized by abnormal movements, red blood cell pathology, and progressive neurodegeneration. Little is understood of the pathogenesis of ChAc and related disorders (collectively Neuroacanthocytosis). The Eighth International Chorea-Acanthocytosis Symposium was held in May 2016 in Ann Arbor, MI, USA, and focused on molecular mechanisms driving ChAc pathophysiology. Accompanying the meeting, members of the neuroacanthocytosis research community and other invited scientists met in a workshop to discuss the current understanding and next steps needed to better understand ChAc pathogenesis. These discussions identified several broad and critical needs for advancing ChAc research and patient care, and led to the definition of 18 specific action points related to functional and molecular studies, animal models, and clinical research. These action points, described below, represent tractable research goals to pursue for the next several years.

description: Presented at the Protections 2016: 2nd international seminar on dam protection against overtopping: concrete dams, embankment dams, levees, tailings dams held on 7th-9th September, 2016, at Colorado State University in Fort Collins, Colorado, USA. The increasing demand for dam and levee safety and flood protection has motivated new research and advancements and a greater need for cost-effective measures in overtopping protection as a solution for overtopping concerns at levees and dams. This seminar will bring together leading experts from practice, research, development, and implementation for two days of knowledge exchange followed by a technical tour of the Colorado State University Hydraulic Laboratory with overtopping flume and wave simulator. This seminar will focus on: Critical issues related to levees and dams; New developments and advanced tools; Overtopping protection systems; System design and performance; Applications and innovative solutions; Case histories of overtopping events; Physical modeling techniques and recent studies; and Numerical modeling methods.
description: Includes bibliographical references.
description: The decision to implement overtopping protection as a dam safety modification alternative can be difficult. The decision involves a conscious decision to allow a dam to overtop for floods above a threshold flood. If a large flood occurs that initiates dam overtopping, there is no turning back, and the dam and the overtopping protection must be able to resist the overtopping flows. The chance of intervention being successful for a dam that is already overtopping, should erosion initiate, would be very unlikely. There is more of a comfort level among many dam engineers in providing conventional solutions to a dam overtopping issue. These traditional measures include raising the dam crest to provide additional surcharge space to store a portion of the flood inflows or providing additional spillway capacity to more closely match the peak flood inflows. There is often the perception among experienced dam engineers that these traditional measures provide a safer solution and pose less risk than an overtopping solution. This paper will present scenarios that demonstrate that in some cases, overtopping protection may be just as safe or the safer alternative, by exposing the downstream population to equal or less risk of dam failure during a large flood event. These scenarios will consist of an embankment dam where a replacement gated spillway alternative will be compared to overtopping protection and a concrete dam where raising of the dam will be compared to providing overtopping protection for the dam foundation.
Is the quantum hydrodynamic analogy more general than the Schroedinger approach?

description: The quantum hydrodynamic analogy (QHA), equivalent to the Schrödinger equation, is investigated and extended to the stochastic case. The investigation shows that in addition to reproducing the standard quantum mechanics the QHA model is able to generally describe the quantum stochastic dynamics leading to the dissipative Schrödinger equation given by Kostin [55] as a particular case. The inspection shows that the QHA is well suited for the treatment of problems where local noise (spatially distributed one) is introduced. In this case the analysis shows that the bi-univocal correspondence between the QHA and the Schrödinger approach breaks down and that the states described by the QHA do not have their corresponding ones into the Schrödinger description.

We show that this model possesses a large set of initial conditions consistent with a successful cosmological model in which an inflationary phase is possible, followed by a matter era to end with dark energy domination. In order to understand the success of the model, we study the general features that unified dark matter (UDM) models should comply and then we analyze some particular models and find their constrictions.

description: We suggest a new possibility for ATLAS and CMS to explore the t-tbar forward-backward asymmetry measured at the Tevatron, by attempting to reconstruct t-tbar events, with one of the tops decaying semileptonically in the central region (|η| < 2.5) and the other decaying hadronically in the forward region (|η| > 2.5). For several models which give comparable Tevatron signals, we study the charge asymmetry at the LHC as a function of cuts on |η| and on the t-tbar invariant mass, m_{t-tbar}. We show that there is an interesting complementarity between cuts on |η| and m_{t-tbar} to suppress the dominant and symmetric gg -> t-tbar rate, and different combinations of cuts enhance the distinguishing power between models. This complementarity is likely to hold in other new physics scenarios as well, which affect the t-tbar cross section, so it motivates extending t-tbar reconstruction to higher |η|.

The role of PSGL-1 in T cell migration and homeostasis
Creators: name: Veerman, Krystle
Publisher: name: University of British Columbia
Year: 2012

description: P-Selectin Glycoprotein Ligand-1 (PSGL-1) is an extracellular glycoprotein expressed on most leukocytes that is important for rolling and tethering of activated leukocytes to areas of inflammation through direct interactions with P-selectin, E-selectin and L-selectin. However, PSGL-1null mice showed subtle defects in their homeostatic T cell profile that cannot be adequately explained by a defect in migration of activated leukocytes. PSGL-1null mice had a reduced number of CD4+ and CD8+ T cells in the peripheral blood but not in the lymph nodes and spleen. T cell subset analysis revealed that there was a severe reduction of naïve T cells in the peripheral blood and a moderate reduction of naïve T cells in the lymph nodes whereas other T cell compartments were not as affected. Here we determined that PSGL-1 was important for the homing of T cells to secondary lymphoid organs and that PSGL-1 functioned independently of selectin interaction. PSGL-1 enhanced T cell homing through an interaction with secondary lymphoid chemokines CCL21 and CCL19. We have also shown that PSGL-1null T cells are delayed in leaving the lymph nodes suggesting PSGL-1 is important in the movement of T cells both in and out of lymph nodes. Therefore, the reduced ability of PSGL-1null T cells to enter lymph nodes and receive survival factors may contribute to disturbed T cell subsets in peripheral blood and lymph nodes of PSGL-1null mice. There is evidence of spontaneous CD8+ T cell specific proliferation in PSGL-1null cells in lymphoreplete environments. This appears to be caused by a combination of factors, namely an increase in lymph node residence time as well as a more rapid proliferative response to the homeostatic cytokines IL-15, IL-2 and IL-4. However, PSGL-1null T cells are also less viable both in vivo and in vitro. Therefore, spontaneous proliferation may be a compensatory mechanism that balances T cell levels to normal in lymph nodes and spleens of PSGL-1null mice. These findings collectively demonstrate a novel, selectin-independent role for PSGL-1 on T cells under non-inflammatory conditions both in T cell homing to secondary lymphoid organs as well as maintenance of T cell homeostasis.

description: Collaborative conservation at the local level continues to struggle, but it holds more promise than other strategies in securing relevant social, economic and ecological benefits. To deliver on this promise, community-based conservation needs investment in local leadership and organizations, new relationships at the regional and national level, and policies that catalyze small-scale, decentralized action on a broad scale towards sustainability. Such investments and support will only be possible if more people understand the nature and potential of this strategy. The ultimate goal is true grass-roots action by individuals and communities to secure the health of their own communities and lands, and, in aggregate, significant national benefits for a generation.

Executive Summary
For several years, many liquefied natural gas (LNG) market observers have been anticipating looser waterborne markets and lower prices. Primarily due to surging exports from Australia and the United States, new supply has been entering the market at an unprecedented pace since mid-2014, and this expansion is set to continue through the end of the decade. However, the physical LNG market does not appear to have loosened substantially, even though spot LNG prices are down from the lofty levels of 2011–14, following Japan’s Fukushima crisis.

The purpose of this paper is to demonstrate that physical LNG markets have remained quite tight in the face of growing supply and to examine an underappreciated driver of this tightness: enormous demand growth by a group of new and emerging LNG importers since 2014. Facilitated by an expanding fleet of floating storage and regasification units (FSRUs), these emerging importers have quickly upended the conventional wisdom that the LNG market has entered a period of structural oversupply.

description: We report new mid-eclipse times of the two close binaries NSVS14256825 and HS0705+6700, harboring an sdB primary and a low-mass main-sequence secondary. Both objects display clear variations in the measured orbital period, which can be explained by the action of a third object orbiting the binary. If this interpretation is correct, the third object in NSVS14256825 is a giant planet with a mass of roughly 12 M_Jup. For HS0705+6700, we provide evidence that strengthens the case for the suggested periodic nature of the eclipse time variation and reduces the uncertainties in the parameters of the brown dwarf implied by that model. The derived period is 8.4 yr and the mass is 31 M_Jup, if the orbit is coplanar with the binary. This research is part of the PlanetFinders project, an ongoing collaboration between professional astronomers and student groups at high schools.

description: Motivated by results from recent particle tracking experiments in turbulence (Xu et al., Nat. Phys. 7, 709 (2011)), we study the Lagrangian time correlations of vorticity alignments with the three eigenvectors of the deformation-rate tensor. We use data from direct numerical simulations (DNS), and explore the predictions of a Lagrangian model for the velocity gradient tensor. We find that the initial increase of correlation of vorticity direction with the most extensive eigen-direction observed by Xu et al. is reproduced accurately using the Lagrangian model, as well as the evolution of correlation with the other two eigendirections. Conversely, time correlations of vorticity direction with the eigen-frame of the pressure Hessian tensor show differences with the model.

description: Background: Although the hallmark feature of essential tremor (ET) is kinetic tremor, patients may exhibit additional motor features (e.g., intention tremor and mild gait ataxia) that are markers of an underlying abnormality of cerebellar function. ET is also a highly familial disorder, but we do not know whether the presence and expression of cerebellar signs are similar across family members. There are simply no published data. The alternative possibility is that these features are not heritable. We tested the specific hypothesis that the presence of cerebellar signs (i.e., intention tremor, tandem gait difficulty) ran in ET families.

Methods: ET probands and relatives enrolled in a genetic study at Yale and Columbia universities underwent a detailed videotaped neurological examination.

Results: There were 187 enrollees (59 probands, 128 affected relatives). In a bivariate logistic regression model, the presence of intention tremor in the proband was not a predictor of the presence of intention tremor in the relatives (odds ratio [OR] = 0.60, 95% confidence interval [CI] = 0.28–1.27, p = 0.18). In a similar model, the presence of greater tandem gait difficulty (i.e., a tandem gait score in the upper quartile) in the proband was not a predictor of the presence of such difficulty in the relatives (OR = 1.22, 95% CI = 0.41–3.66, p = 0.73).

Discussion: The presence of cerebellar signs did not aggregate in families with ET. In the current dataset, these did not seem to be disease features that were heritable.

description: One of the key motivations for the development of atomically resolved spectroscopic imaging STM (SI-STM) has been to probe the electronic structure of cuprate high temperature superconductors. In both the d-wave superconducting (dSC) and the pseudogap (PG) phases of underdoped cuprates, two distinct classes of electronic states are observed using SI-STM. The first class consists of the dispersive Bogoliubov quasiparticles of a homogeneous d-wave superconductor. These are detected below a lower energy scale |E|=Δ0 and only upon a momentum space (k-space) arc which terminates near the lines connecting k=\pm(π/a0,0) to k=\pm(0, π/a0). In both the dSC and PG phases, the only broken symmetries detected in the |E|\leq Δ0 states are those of a d-wave superconductor. The second class of states occurs at energies near the pseudogap energy scale |E| Δ1 which is associated conventionally with the 'antinodal' states near k=\pm(π/a0,0) and k=\pm(0, π/a0). We find that these states break the 90o-rotational (C4) symmetry of electronic structure within CuO2 unit cells, at least down to 180o rotational (C2) symmetry (nematic) but in a spatially disordered fashion. This intra-unit-cell C4 symmetry breaking coexists at |E| Δ1 with incommensurate conductance modulations locally breaking both rotational and translational symmetries (smectic). The properties of these two classes of |E| Δ1 states are indistinguishable in the dSC and PG phases. To explain this segregation of k-space into the two regimes distinguished by the symmetries of their electronic states and their energy scales |E| Δ1 and |E|\leqΔ0, and to understand how this impacts the electronic phase diagram and the mechanism of high-Tc superconductivity, represents one of a key challenges for cuprate studies.

description: This paper develops results for the next nearest neighbour Ising model on random graphs. Besides being an essential ingredient in classic models for frustrated systems, second neighbour interactions interactions arise naturally in several applications such as the colour diversity problem and graphical games. We demonstrate ensembles of random graphs, including regular connectivity graphs, that have a periodic variation of free energy, with either the ratio of nearest to next nearest couplings, or the mean number of nearest neighbours. When the coupling ratio is integer paramagnetic phases can be found at zero temperature. This is shown to be related to the locked or unlocked nature of the interactions. For anti-ferromagnetic couplings, spin glass phases are demonstrated at low temperature. The interaction structure is formulated as a factor graph, the solution on a tree is developed. The replica symmetric and energetic one-step replica symmetry breaking solution is developed using the cavity method. We calculate within these frameworks the phase diagram and demonstrate the existence of dynamical transitions at zero temperature for cases of anti-ferromagnetic coupling on regular and inhomogeneous random graphs.

Torticollis

description: Background: Cervical dystonia, also known as spasmodic torticollis, is a chronic disorder in which patients exhibit involuntary repetitive contractions of neck muscles resulting in abnormal postures or movements. Occasionally, there is also a dystonic head tremor. The underlying mechanisms for cervical dystonia and dystonic tremor are not clear, and treatments are limited.

Case Report: In the present cases, two females with head tremor starting in adolescence developed worsening symptoms of cervical dystonia with dystonic tremor in their 60s. On osteopathic physical examination, both had a vertical type strain to the sphenobasilar synchondrosis.

Discussion: Vertical strains are more frequently found in patients after head trauma, congenital or later in life, than in healthy patients, and head trauma may have been a precipitating factor in these patients. There were improvements in cervical dystonia symptoms, including tremor, in both patients after osteopathic manual treatment.
Social Impact Bonds: A Tax-Favored Investment?

description: Social impact bonds (SIBs) have recently generated a lot of excitement nationwide as an innovative way to finance social projects. A SIB is a financing mechanism that uses private capital to fund social services, with the government only repaying investors their capital plus a potential return on investment if improved social outcomes are achieved. As such, it brings together the private, public, and non-profit sectors in a manner that unlocks an additional source of capital to fund social service providers, promotes innovation, encourages interagency cooperation, and creates more accountability. Despite these benefits, tax law likely hinders the development of SIB-funded programs in the United States by discouraging private investment in SIBs.

This Article is the first to consider the role of U.S. tax law in promoting SIB investments by examining the tax implications of a SIB investment from both a doctrinal and policy perspective. It concludes that the current tax system creates unnecessary compliance risks for private SIB investors and unjustifiably treats SIB investments less favorably than comparable investments, thereby increasing administrative complexity, distorting investment decisions, and creating inequities among similarly situated investors. Given the unintended discriminatory tax treatment towards SIBs, this Article argues that Congress should consider enacting legislation to make a SIB investment a tax-favored investment. This change could best be achieved by extending preferential tax rates to SIB earnings, exempting SIB earnings from taxation, or by allowing an upfront deduction for contributions to SIB investments. By modifying the tax law to treat SIB investments more in parity with comparable investments, SIB-funded programs will likely attract additional private capital and allow SIBs to potentially make a meaningful impact on some of our nation’s most challenging social problems

description: Fading is the time-dependent variation in transmitted signal strength through a complex medium, due to interference or temporally evolving multipath scattering. In this paper we use random matrix theory (RMT) to establish a first-principles model for fading, including both universal and non-universal effects. This model provides a more general understanding of the most common statistical models (Rayleigh fading and Rice fading) and provides a detailed physical basis for their parameters. We also report experimental tests on two ray-chaotic microwave cavities. The results show that our RMT model agrees with the Rayleigh/Rice models in the high loss regime, but there are strong deviations in low-loss systems where the RMT approach describes the data well.

Soldiers with Fortunes? Rethinking the Tax Treatment of Fallen Combatants

description: Section 2201 of the Internal Revenue Code provides a partial estate tax exemption for members of the armed forces who die in, or as a result of, combat operations. In this Article, I explore the origins of this exemption and assess the extent to which it serves three important policy goals: (1) reducing financial and administrative burdens on military families, (2) incentivizing military service, and (3) avoiding the moral hazard of the government being able to “profit” (through increased tax revenues) as a result of combat deaths.

Through this analysis, I conclude that this arguably well-intentioned provision does little to serve these three policy ends. I urge Congress to abandon the provision and replace it with expanded, simplified, income tax relief for the families of those lost in combat. This income tax relief will better serve the enumerated policy goals than does the current combat exemption, offering more meaningful relief to more typical military families.

description: The second part of the Birch and Swinnerton-Dyer (BSD) conjecture gives a conjectural formula for the order of the Shafarevich-Tate group of an elliptic curve in terms of other computable invariants of the curve. Cremona and Mazur initiated a theory that can often be used to verify the BSD conjecture by constructing non-trivial elements of the Shafarevich-Tate group of an elliptic curve by means of the Mordell-Weil group of an ambient curve. In this paper, we generalize Cremona and Mazur's work and give precise conditions under which such a construction can be made for the Shafarevich-Tate group of an abelian variety over a number field. We then give an extension of our general result that provides new theoretical evidence for the BSD conjecture.
