description: In the partonic (or light-front) description of relativistic systems the electromagnetic form factors are expressed in terms of frame-independent charge and magnetization densities in transverse space. This formulation allows one to identify the chiral components of nucleon structure as the peripheral densities at transverse distances b = O(M_pi^{-1}) and compute them in a parametrically controlled manner. A dispersion relation connects the large-distance behavior of the transverse charge and magnetization densities to the spectral functions of the Dirac and Pauli form factors near the two-pion threshold at timelike t = 4 M_pi^2. Using relativistic chiral effective field theory in the leading-order approximation, we (a) derive the asymptotic behavior (Yukawa tail) of the isovector transverse densities in the "chiral" region b = O(M_pi^{-1}) and the "molecular" region b = O(M_N^2/M_pi^3); (b) perform the heavy-baryon expansion; (c) explain the relative magnitude of the peripheral charge and magnetization densities in a simple mechanical picture; (d) include Delta intermediate states and study the densities in the large-N_c limit of QCD; (e) quantify the spatial region where the chiral components are numerically dominant; (f) calculate the chiral divergences of the b^2-weighted moments of the transverse densities (charge and magnetic radii) and determine their spatial support. Our approach provides a concise formulation of the spatial structure of the nucleon's chiral component and offers new insights into basic properties of the chiral expansion. It relates the information extracted from low-t elastic form factors to the generalized parton distributions probed in peripheral high-energy scattering processes.

description: Background: In genetic research on essential tremor (ET), certain individuals may be particularly challenging to categorize diagnostically.

Methods: In the Family Study of Essential Tremor (>200 enrollees), 28 participants with borderline clinical findings who did not meet strict criteria for ET were assigned final diagnoses of ET. We scrutinized the clinical features of these cases and the sensitivity/specificity of certain features that best separated them from 19 unaffected individuals.

Results: Borderline ET cases differed from unaffected individuals in eight features: total tremor score, at least one kinetic tremor rating ≥1.5, at least one kinetic tremor rating ≥1.5 in the dominant arm, tremor rating during spiral drawing ≥1.5, higher spiral axis score, head tremor, complaint of tremor, and comment on tremor by others. The combination of at least one kinetic tremor rating ≥1.5 in the dominant arm and the presence of at least three of the remaining seven features predicted the clinician‐assigned diagnosis in 88.6% of borderline ET vs. unaffected individuals (sensitivity 84.6%, specificity 94.4%).

Discussion: In a family study, a small number of clinical features characterized borderline ET, and a particular combination of these separated the majority of these borderline cases from normals. These analyses may help researchers minimize diagnostic misclassification.
Elucidating the Nature and Mechanism of Tic Improvement in Tourette Syndrome: A Pilot Study

description: Background: For unclear reasons, many Tourette syndrome (TS) children report near‐complete tic remission by young adulthood. Immature maturation of brain networks, observed with resting‐state functional MRI (rs‐fc‐MRI) in adolescents and adults with TS, might evolve to a mature pattern in adults who experience tic improvement or remission. We explored the feasibility of testing this hypothesis in our population of young adult TS males, each with prior clinical assessments completed during childhood as part of a separate TS Association Genetics Consortium study.

Methods: A total of 10 TS males (off tic suppressing drugs for at least 6 months) aged 19–32 years, mean follow‐up interval 7.5 (2 to 13) years, and 11 neurologically normal controls were enrolled and underwent 3‐Tesla structural and rs‐fc‐MRI sequences.

Results: The mean change in Yale Global Tic Severity Scale (YGTSS) was −31.5% (total) and −26.6% (YGTSS motor+vocal). Two subjects reported resolution of tic‐related disability, with drops from mean 45 to 16.5 (YGTSS‐total) and 25 to 11.5 (YGTSS motor+vocal.). Rs‐fc‐MRI revealed significantly increased connectivity between the ipsilateral anterior and mid cingulate cortex and striatum, increased connectivity between local connections, and decreased connectivity between more distant connections; representing an immature connectivity pattern.

Discussion: Similar to previous reports, we found immature patterns of functional connectivity in adult TS subjects. Despite a lack of complete tic remission, two subjects exhibited dramatic drops in tic severity that correlated with tic‐related disability improvement. More work is needed to elucidate the mechanism of such dramatic improvement in TS.

description: We investigate the radiative transfer of Lyman alpha photons through simplified anisotropic gas distributions, which represent physically motivated extensions of the popular 'shell-models'. Our study is motivated by the notion that (i) shell models do not always reproduce observed Lyman alpha spectral line profiles, (ii) (typical) shell models do not allow for the escape of ionizing photons, and (iii) the observation & expectation that winds are more complex, anisotropic phenomena. We examine the influence of inclination on the Lyman alpha spectra, relative fluxes and escape fractions. We find the flux to be enhanced/suppressed by factors up to a few depending on the parameter range of the models, corresponding to a boost in equivalent width of the same amplitude if we neglect dust. In general, lower mean optical depths tend to reduce the impact of anisotropies as is expected. We find a correlation between an observed peak in the -- occasionally triple-peaked -- spectrum at the systemic velocity and the existence of a low optical depth cavity along the line of sight. This can be of importance in the search for ionizing photons leaking from high- redshift galaxies since these photons will also be able to escape through the cavity.

description: Background: Several genes associated with dystonia have been identified. A mutation in one of these, THAP1 (DYT6), is linked to isolated dystonia. The aim of this study was to assess the prevalence of THAP1 gene mutations and the clinical characteristics of patients with these mutations in a clinical population in Brazil.

Methods: Seventy‐four patients presenting with dystonia involving the cervical muscles and without mutations in the TOR1A (DYT1) gene or any other movement disorders were recruited at a movement disorders clinic between June 2008 and June 2009. All the patients underwent clinical examination and were screened for mutations of the THAP1 gene.

Results: Three patients had the novel p.Gln97Ter THAP1 nonsense mutation in heterozygosis. One of them had no family history of dystonia. Symptoms in this patient first appeared in his right arm, and the condition progressed to the generalized form. The other two patients belonged to the same family (cousins). Symptoms in the first patient started in her right arm at the age of 18 years and the condition progressed to the segmental form. The second patient, who carried the p.Arg169Gln missense mutation, developed dystonia in her left arm at the age of 6 years. The condition progressed to generalized dystonia.

Discussion: We conclude that THAP1 mutations are also a cause, albeit uncommon, of segmental and generalized dystonia in the Brazilian population.

description: Long time horizons and social distance are often viewed as key barriers to pro-environmental action due to intertemporal and interpersonal discounting, particularly in the case of climate change. We suggest that these challenges can be turned into opportunities by making salient relevant long-term goals and motives, thus shifting preferences for present-future and self-other trade-offs at the point of decision-making. Here we test whether individuals’ latent motivation to leave a positive legacy can be leveraged to increase engagement with climate change and other long-term environmental problems. In an initial study, we find that individual differences in legacy motivation are positively associated with pro-environmental behaviors and intentions. In an experiment, we demonstrate that priming legacy motives prior to providing an opportunity to donate to an environmental charity increases donations, as well as self-reported pro-environmental intentions and beliefs. Using a new short-form scale designed to measure legacy motives, we confirm that changes in environmental behavior and belief induced by the legacy prime are mediated by increased concern for one’s future legacy. This work provides the first experimental evidence that domain-general legacy motives can be exploited to support intergenerational environmental stewardship, and represents a previously under-studied and powerful strategy for increasing pro-environmental behavior.

description: Absorption of a photon by an electron moving parallel to a rough surface is studied.In the weak scattering regime we have evaluated the absorption probability of absorption of a single photon. It is shown the absorption probability with diffusional contribution becomes large by a lin/l factor compared to the analogous result with the single scattering contribution. The maximum of probability takes place for the infrared wavelengths and strongly depends on the particle energy. We also discuss the case of two-dimensional periodical surface profile and indicate optimal conditions for maximal absorption probability. The results can be used in electron energy gain spectroscopy and in laser-driven acceleration.

description: Semiconductor-based biointerfaces are typically established either on the surface of the plasma membrane or within the cytoplasm. In gram-negative bacteria, the periplasmic space, characterized by its confinement and the presence of numerous enzymes and peptidoglycans, offers additional opportunities for biomineralization, allowing for non-genetic modulation interfaces. Here, we demonstrate semiconductor nanocluster precipitation containing single- and multiple-metal elements within the periplasm, as observed through various electron- and X-ray-based imaging techniques. The periplasmic semiconductors are metastable and display defect-dominant fluorescent properties. Surprisingly, the defect-rich (i.e., the low-grade) semiconductor nanoclusters produced in situ can still increase adenosine triphosphate levels and malate production when coupled with photosensitization. We expand the sustainability levels of the biohybrid system to include reducing heavy metals at the primary level, building living bioreactors at the secondary level, and creating semi-artificial photosynthesis at the tertiary level. The biomineralization-enabled periplasmic biohybrids have the potential to serve as defect-tolerant platforms for diverse sustainable applications.

title: The nature of censorship and regulation of the darknet in the Digital Age
Creators: name: Peteva, Petya
Publisher: name: Wydawnictwo C.H. Beck
Year: 2020

description: Latest data from Freedom House shows that, up to date, over 3.8 billion people have access to the Internet. With the advance of the Information Age and with the ever-growing number of Internet users worldwide, multiple heated debates continue taking place on whether cyberspace should be regulated and/or censored, and to what extent, so that it strikes the right balance between respecting fundamental human rights, such as freedom of expression on the one hand, and ensuring public security and safety on the other. While cyberspace censorship has turned to be a political hot potato, there are still corners of cyberspace that, in the meantime, are practically unregulatable due to their anonymity and intractability of their users. This so-called „darknet”, while not without its benefits, has also infamously posed a considerable obstacle for law enforcement authorities in combating crime and has provided a safe haven for nefarious individuals and illegal activities to take place with impunity.

description: Background: Non‐motor symptoms, quality of life, service needs, and barriers to care of individuals with movement disorders are not well explored. This study assessed these domains within a sample of individuals with essential tremor (ET) and Parkinson's disease (PD).

Methods: A survey exploring symptoms, needs, and barriers to care was disseminated to a convenience sample (N = 96) of individuals with a primary diagnosis of ET (N = 19) or PD (N = 77).

Results: Similarities in overall quality of life and impact on daily functioning were found across individuals with ET and PD. Noteworthy differences included endorsement of different types of service needs and utilization patterns and fewer non‐motor symptoms reported among those with ET (M = 6.1, SD = 2.4) than those with PD (M = 10.4, SD = 3.4). Non‐motor symptoms significantly impacted movement disorder‐related quality of life for both diagnostic groups, but this relationship was stronger for individuals with ET, t(12) = 3.69, p = 0.003, β = 0.73 than with PD, t(56) = 4.00, p less than 0.001, β = 0.47. Individuals with ET also reported higher rates of stigma (31.6% vs. 7.8%) and greater impact of non‐motor symptoms on emotional well‐being, R2 = 0.37, F(1, 13) = 7.17, p = 0.020.

Discussion: This is the first study to describe and compare the needs, barriers to care, and impact on quality of life of two distinct movement disorder groups. Our results support the recent efforts of the field to identify interventions to address the non‐motor symptoms of movement disorders and indicate need for greater appreciation of the specific differences in symptoms and quality of life experienced across movement disorder diagnoses.

description: The exact expression for the effective resistance between any two vertices of the $N$-cycle graph with four nearest neighbors $C_{N}(1,2)$, is given. It turns out that this expression is written in terms of the effective resistance of the $N$-cycle graph $C_{N}$, the square of the Fibonacci numbers, and the bisected Fibonacci numbers. As a consequence closed form formulas for the total effective resistance, the first passage time (FPT), and the mean first passage time (MFPT) for the simple random walk on the the $N$-cycle graph with four nearest neighbors are obtained. Finally, a closed form formula for the effective resistance of $C_{N}(1,2)$ with all first neighbors removed is obtained.

description: In this paper, we propose a new rate control algorithm for conversational multimedia flows. In our approach, along with Real-time Transport Protocol (RTP) media packets, we propose sending redundant packets to probe for available bandwidth. These redundant packets are Forward Error Correction (FEC) encoded RTP packets. A straightforward interpretation is that if no losses occur, the sender can increase the sending rate to include the FEC bit rate, and in the case of losses due to congestion the redundant packets help in recovering the lost packets. We also show that by varying the FEC bit rate, the sender is able to conservatively or aggressively probe for available bandwidth. We evaluate our FEC-based Rate Adaptation (FBRA) algorithm in a network simulator and in the real-world and compare it to other congestion control algorithms.

description: Background: In recent studies primary bowing tremor has been described; however, tremor frequency has never been quantitatively assessed. In addition to describing phenomenological aspects of tremor we thus aimed at assessing tremor frequency. Our hypothesis was that primary bowing tremor is similar to the phenomenological aspects and frequency of primary writing tremor.

Methods: We quantified primary bowing tremor in four violinists under two conditions: open strings and a G major scale. Data were analyzed using empirical mode decomposition because it takes into account non‐stationarity and non‐linearity of signals. For each patient we further described tremor phenomenology and assessed symptom onset, risk factors, medication, and family history with a structured anamnesis. We compare the findings to previous findings for primary bowing tremor and primary writing tremor.

Results: We mainly found a flexion–extension tremor of the wrist with a frequency range of 4.7–6.7 Hz. There was no significant difference between the conditions. Mean onset age was 43±2.4 years. Medication included trihexyphenidyl, propranolol, primidone, and botulinum toxin. We found a positive family history in two patients and an injury prior to symptom onset in another two patients. Comparison of onset age, frequency range, family history, and injuries prior to onset revealed that our findings are very similar to previous findings on primary bowing tremor and primary writing tremor.

Discussion: Our findings confirmed our hypothesis that primary bowing tremor is similar to primary writing tremor, with regard to phenomenology and epidemiology as well as tremor frequency. There was no difference in tremor frequency between conditions, suggesting that tremor is not influenced by bimanual coordination or bowing speed. Our findings thus provide new phenomenological aspects and may contribute to a better understanding of primary bowing tremor.

description: Background: XCiDaBLE is a large, prospective, observational “naturalistic” study evaluating Xeomin® for Cervical Dystonia or BLEpharospasm in the United States. We report the interim results from the blepharospasm cohort of XCiDaBLE.

Methods: Subjects (≥18 years old) with blepharospasm were followed for two treatment cycles of incobotulinumtoxinA and monitored for 4 weeks after injection via interactive voice/web response system (IVRS/IWRS). The investigator‐reported scale includes the Clinical Global Impression Scale‐Severity subscale (CGI‐S). Patient‐reported outcome measures include the Patient Global Impression Scale‐Severity (PGI‐S) and ‐Improvement (PGI‐I) subscales, Jankovic Rating Scale (JRS), SF‐12v2® health survey, and Work Productivity and Activity Impairment questionnaire. Subjects are seen by the investigator at baseline (including the first injection), during the second injection, and at a final study visit (12 weeks after the second injection).

Results: One hundred seventy subjects were included in this interim analysis. The majority of subjects were female (77.1%) and white (91.8%), and had previously been treated with botulinum toxins (96.5%). The mean total dose (both eyes) was 71.5 U of incobotulinumtoxinA for the first injection. PGI‐S, PGI‐I, and JRS scores were significantly improved 4 weeks after treatment (all p less than 0.0001). No differences were noted in either quality of life (QoL) or work productivity in this short assessment period. No unexpected adverse events occurred.

Discussion: This is an interim study and assessment method based on an IVRS/IWRS. In this predominantly toxin‐experienced cohort, significant benefits in specific and global measures of disease severity were seen in the immediate post‐incobotulinumtoxinA injection period. It will be interesting to see if there are improvements in QoL with consistent individualized injections over a longer period.

Modeling and Mining Multi-Aspect Graphs With Scalable Streaming Tensor Decomposition
Creators: name: Gujral, Ekta
Publisher: name: figshare
Year: 2022
Subjects: Applied Computer Science

description: Graphs emerge in almost every real-world application domain, ranging from online social networks all the way to health data and movie viewership patterns. Typically, such real-world graphs are big and dynamic, in the sense that they evolve over time. Furthermore, graphs usually contain multi-aspect information i.e. in a social network, we can have the "means of communication" between nodes, such as who messages whom, who calls whom, and who comments on whose timeline and so on.
 How can we model and mine useful patterns, such as communities of nodes in that graph, from such multi-aspect graphs? How can we identify dynamic patterns in those graphs, and how can we deal with streaming data, when the volume of data to be processed is very large? In order to answer those questions, in this thesis, we propose novel tensor-based methods for mining static and dynamic multi-aspect graphs. In general, a tensor is a higher-order generalization of a matrix that can represent high-dimensional multi-aspect data such as time-evolving networks, collaboration networks, and spatio-temporal data like Electroencephalography (EEG) brain measurements.
 The thesis is organized in two synergistic thrusts: First, we focus on static multi-aspect graphs, where the goal is to identify coherent communities and patterns between nodes by leveraging the tensor structure in the data. Second, as our graphs evolve dynamically, we focus on handling such streaming updates in the data without having to re-compute the decomposition, but incrementally update the existing results.
The German Musical Exile and the Course of American Musicology
Creators: name: Josephson, David
Publisher: name: Columbia University
Year: 2005
Subjects: Music

description: On the face of it, the subject would seem not to need a paper. Musicology
was a European discipline fed from many sources, named by Friedrich
Chrysander (1863, 1867), defined by Guido Adler (1885), and, during its
early twentieth-century course, shaped by Friedrich Ludwig and Hugo Riemann.
Like other humanities during the muscular growth of Wilhelmine
Germany, it became a German province. As America had taken its classical
music from Germany during the nineteenth century, so it took its musicology
from Germany in the early years of the twentieth. But our pioneers
soon set out to create a distinctly American musicology, and were on their
way to doing so from the founding of the Musical Quarterly in 1915 to the
creation of the New York Musicological Society in 1931 and its reorganization
as the American Musicological Society (AMS) three years later.3 They
were soon overtaken by an unexpected influx of emigre scholars in flight
from central Europe whose numbers and prestige charted the course of the
fledgling discipline anew. Eventually, as the emigres passed from the scene,
and the generations of those they had taught began to pass from it as well,
their influence eroded and American musicology reclaimed its national
character, however that character would come to be construed. It seems a
straightforward story.
It isn't. That story tells us little about why we did what we did during
the early decades of our Society's existence. It narrates the meteoric rise of
the emigres' influence, but fails to account for its seemingly sudden collapse.
When in 1985 Joseph Kerman published a stunning critique of postwar
Anglo-American scholarship-he had been fighting the battle for twenty
years before that-Margaret Bent responded as President of the AMS with
an Address at the Society's annual meeting that year in Vancouver, defending
the classic paradigm with the authority of one who was its elegant voice and
the passion of one who recognized what was at stake (Kerman 1985; Bent
1986). But by the annual meeting in 1990 in Oakland the field had become
a Babel of voices.
Resonances in the Photoionization Cross Sections of Atomic Nitrogen Shape the Far-Ultraviolet Spectrum of the Bright Star in 47 Tucanae

description: The far-ultraviolet (FUV) spectrum of the Bright Star (B8 III) in 47 Tuc (NGC 104) shows a remarkable pattern: it is well fit by LTE models at wavelengths longer than Lyman beta, but at shorter wavelengths it is fainter than the models by a factor of two. A spectrum of this star obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) shows broad absorption troughs with sharp edges at 995 and 1010 A and a deep absorption feature at 1072 A, none of which are predicted by the models. We find that these features are caused by resonances in the photoionization cross sections of the first and second excited states of atomic nitrogen (2s$^2$ 2p$^3$ $^2$D$^0$ and $^2$P$^0$). Using cross sections from the Opacity Project, we can reproduce these features, but only if we use the cross sections at their full resolution, rather than the resonance-averaged cross sections usually employed to model stellar atmospheres. These resonances are strongest in stellar atmospheres with enhanced nitrogen and depleted carbon abundances, a pattern typical of post-AGB stars.

title: Working with Long-Term Health Conditions and Health Behaviours
Creators: name: Kausar, K
Publisher: name: Liverpool John Moores University
Year: 2020

description: This portfolio details work completed for the purpose of fulfilling the five competencies that form the Professional Doctorate in Health Psychology. The competencies are research; assessed via a systematic review and two research papers, behaviour change intervention (BCI); assessed by two case studies, consultancy; assessed via the contract/report and a case study, teaching and training; assessed via a case study and diary, and professional competence; assessed by a log of activities and reflective case study. At the start of training, the trainee worked as a Psychological Wellbeing Practitioner within one NHS trust, alongside volunteering as a trainee Health Psychologist in another. However, the voluntary role was short-lived. The trainee progressed to the role of a senior therapist within the first organisation after some time, and subsequently to the official role of a Health Psychologist in Training. The professional competence was fulfilled throughout training by working in accordance with the BPS/HCPC guidelines and codes of conduct. A copy of the trainee’s log of training, signed by the trainee’s supervisor, is included in this portfolio alongside a reflective case study and separate reflection on adhering to the BPS/HCPC guidelines. For the research competence, a systematic review was undertaken, focussed on exploring the effectiveness of group cognitive behavioural therapy for Chronic Fatigue Syndrome (CFS). Furthermore, a research paper was completed outlining the effectiveness of graded exposure therapy for an eating phobia and a second paper evaluating a series of group therapy pilots for CFS. The work included in the two empirical research papers were initially developed and delivered as part of the BCI competence and case studies were submitted on these for the fulfilment of this competence. Additionally, links were developed with a university tutor for the purpose of consultancy, and subsequently developed and delivered a teaching lecture to a large group of BSc and MSc Psychology students. A training series was developed on ‘working with long-term health conditions’ to NHS health staff for the teaching and training competence.

description: Background: The visual temporal discrimination threshold (TDT) is the shortest time interval at which one can determine two stimuli to be asynchronous and meets criteria for a valid endophenotype in adult‐onset idiopathic focal dystonia, a poorly penetrant disorder. Temporal discrimination is assessed in the hospital laboratory; in unaffected relatives of multiplex adult‐onset dystonia patients distance from the hospital is a barrier to data acquisition. We devised a portable headset method for visual temporal discrimination determination and our aim was to validate this portable tool against the traditional laboratory‐based method in a group of patients and in a large cohort of healthy controls.

Methods: Visual TDTs were examined in two groups 1) in 96 healthy control participants divided by age and gender, and 2) in 33 cervical dystonia patients, using two methods of data acquisition, the traditional table‐top laboratory‐based system, and the novel portable headset method. The order of assessment was randomized in the control group. The results obtained by each technique were compared.

Results: Visual temporal discrimination in healthy control participants demonstrated similar age and gender effects by the headset method as found by the table‐top examination. There were no significant differences between visual TDTs obtained using the two methods, both for the control participants and for the cervical dystonia patients. Bland–Altman testing showed good concordance between the two methods in both patients and in controls.

Discussion: The portable headset device is a reliable and accurate method for visual temporal discrimination testing for use outside the laboratory, and will facilitate increased TDT data collection outside of the hospital setting. This is of particular importance in multiplex families where data collection in all available members of the pedigree is important for exome sequencing studies.

description: We consider a model of a random height function with long-range constraints on a discrete segment. This model was suggested by Benjamini, Yadin and Yehudayoff and is a generalization of simple random walk. The random function is uniformly sampled from all graph homomorphisms from the graph P_{n,d} to the integers Z, where the graph P_{n,d} is the discrete segment {0,1,..., n} with edges between vertices of different parity whose distance is at most 2d+1. Such a graph homomorphism can be viewed as a height function whose values change by exactly one along edges of the graph P_{n,d}. We also consider a similarly defined model on the discrete torus. Benjamini, Yadin and Yehudayoff conjectured that this model undergoes a phase transition from a delocalized to a localized phase when d grows beyond a threshold c*log(n). We establish this conjecture with the precise threshold log_2(n). Our results provide information on the typical range and variance of the height function for every given pair of n and d, including the critical case when d-log_2(n) tends to a constant. In addition, we identify the local limit of the model, when d is constant and n tends to infinity, as an explicitly defined Markov chain.

description: The study examined the impact of climate change on growth in Nigeria, employing the error Correction Model and ordinary least squares (OLS) estimation technique using data for the period 1981-2021. Changes in temperature and carbon emission were used to capture climate change, while energy consumption was used as a control variable. The results indicate that in the long run, carbon emissions affect growth adversely. In addition, energy consumption impacts positively growth in the short run and long run. These results imply that the Nigerian government should evolve and implement policies to curb carbon emissions. In particular, a National Climate Change Commission is required in Nigeria to deal with all climate change issues. Furthermore, the finding that energy consumption stimulates growth in Nigeria means that policymakers/governments at all levels in Nigeria should evolve and implement policies to encourage these desirable outcomes.
The Continuum Emission Spectrum of Hf 2-2 near the Balmer Limit and the ORL versus CEL abundance and temperature Discrepancy

description: The continuum spectrum of the planetary nebula Hf 2-2 close to the Balmer discontinuity is modeled in the context of the long standing problem of the abundance and temperature discrepancy found when analyzing optical recombination lines and collisionally excited forbidden lines in nebulae. Models are constructed using single and double Maxwell-Boltzmann distributions as well as kappa-distributions for the energies of the free electrons. New results for the necessary continuum and line emission coefficients are presented calculated with kappa-distributed energies. The best fit to the observed continuum spectrum is found to be a model comprising two components with dramatically different temperatures and with a Maxwell-Boltzmann distribution of electron energies. On the basis of a chi-squared analysis, this model is strongly favored over a model with kappa-distributed electron energies.

Coexistence of diffusive resistance and ballistic persistent current in disordered metallic rings with rough edges: Possible origin of puzzling experimental values

description: Typical persistent current ($I_{typ}$) in a mesoscopic normal metal ring with disorder due to rough edges and random grain boundaries is calculated by a scattering matrix method. In addition, resistance of a corresponding metallic wire is obtained from the Landauer formula and the electron mean free path ($l$) is determined. If disorder is due to the rough edges, a ballistic persistent current $I_{typ} \simeq e v_F/L$ is found to coexist with the diffusive resistance ($ \propto L/l$), where $v_F$ is the Fermi velocity and $L \gg l$ is the ring length. This ballistic current is due to a single electron that moves almost in parallel with the rough edges and thus hits them rarely (it is shown that this parallel motion exists in the ring geometry owing to the Hartree-Fock interaction). Our finding agrees with a puzzling experimental result $I_{typ}\simeq e v_F/L$, reported by Chandrasekhar et al. [Phys. Rev. Lett. \textbf{67}, 3578 (1991)] for metallic rings of length $L \simeq 100 l$. If disorder is due to the grain boundaries, our data reproduce theoretical result $I_{typ}\simeq (e v_F/L) (l/L)$ that holds for the white-noise-like disorder and has been observed in recent experiments. Thus, result $I_{typ}\simeq e v_F/L$ in a disordered metallic ring of length $L \gg l$ is as normal as result $I_{typ}\simeq (e v_F/L)(l/L)$. Which result is observed depends on the nature of disorder. Experiments that would determine $I_{typ}$ and $l$ in correlation with the nature of disorder can be instructive.

description: Background: Posterior cortical atrophy is a clinical syndrome that is characterized by the progressive loss of visuospatial integration and is associated with neurodegenerative conditions.

Case Report: We describe a 60‐year‐old female with simultanagnosia, oculomotor apraxia, and optic ataxia for which she received an initial clinical diagnosis of posterior cortical atrophy. Three years later, she developed Balint's syndrome, Gerstmann's syndrome, left alien hand syndrome, smooth asymmetric (left) rigidity, cortical sensory loss, and spontaneous myoclonic jerks of the left arm, which suggested a final diagnosis of corticobasal syndrome.

Discussion: This case report indicates that corticobasal syndrome may present with visuospatial deficits.
