The introduction of CAD/CAM technology in dentistry opened the way for the use of numerous materials for prosthetic restorations: dental alloys, ceramic masses, zirconia, PMMA, etc. One of the materials suitable for CAD/CAM technology is zirconia, used either ceramic-plated or full-contour, through its mechanical and optical properties. Zirconia, proves to be a real competitor for dental alloys used in porcelain fused to metal technology, with great results on posterior and frontal areas of dental arches. Prosthetic restorations made of zirconia in transit areas (including canines and premolars) exemplify the perfect combination between mechanical resistance and aesthetics of this material.

Bulk Flow Motion Detection in the Local Universe with Pantheon+ Type Ia Supernovae
Authors: Lopes Maria , Bernui Armando , Franco Camila , Avila Felipe
Published: May 2024

The bulk flow in the Local Universe is a collective phenomenon due to the peculiar motions of matter structures, which, instead of moving in random directions, appears to follow an approximate dipole velocity flow. We apply a directional analysis to investigate, through the Hubble-Lemaître diagram, the angular dependence of the Hubble constant H
0 of a sample of Type Ia supernovae from the Pantheon+ catalog in the Local Universe (0.015 ≤ z ≤ 0.06). We perform a directional analysis that reveals a statistically significant dipole variation of H
0, at more than 99.9% confidence level, showing that matter structures follow a dipole bulk flow motion toward (l, b) = (326.°1 ± 11.°2, 27.°8 ± 11.°2), close to the Shapley supercluster (l
Shapley, b
Shapley) = (311.°5, 32.°3), with velocity 132.14 ± 109.3 km s−1 at the effective distance 102.83 ± 10.2 Mpc. Interestingly, the antipodal direction of this dipole points close to the Dipole Repeller structure. Our analyses confirm that the gravitational dipole system Shapley-Dipole Repeller explains well the observed bulk flow velocity field in the Local Universe. Furthermore, we performed robustness tests that support our results. Additionally, our approach provides a measurement of the Hubble constant H
0 = 70.39 ± 1.4 km s−1 Mpc−1, at the effective distance 102.8 Mpc, z ≃ 0.025.
Investigating Mass Segregation of the Binary Stars in the Open Cluster NGC 6819
Authors: Zwicker Claire , Geller Aaron M. , Childs Anna C. , Motherway Erin , von Hippel Ted
Published: May 2024

We search for mass segregation in the intermediate-aged open cluster NGC 6819 within a carefully identified sample of probable cluster members. Using photometry from Gaia, Pan-STARRS, and the Two Micron All Sky Survey as inputs for a Bayesian statistics software suite, BASE-9, we identify a rich population of (photometric) binaries and derive posterior distributions for the cluster age, distance, metallicity, and reddening, as well as star-by-star photometric membership probabilities, masses, and mass ratios (for binaries). Within our entire sample, we identify 2632 cluster members and 777 binaries. We then select a main-sequence “primary sample” with 14.85 <G < 19.5, containing 1342 cluster members and 250 binaries with mass ratios q > 0.5, to investigate mass segregation. Within this primary sample, we find the binary radial distribution is significantly shifted toward the cluster center as compared to the single stars, resulting in a binary fraction that increases significantly toward the cluster core. Furthermore, we find that within the binary sample, more massive binaries have more centrally concentrated radial distributions than less massive binaries. The same is true for the single stars. We verify the expectation of mass segregation for this stellar sample in NGC 6819 through both relaxation time arguments and by investigating a sophisticated N-body model of the cluster. Importantly, this is the first study to investigate mass segregation of the binaries in the open cluster NGC 6819.
Impact of Ejecta Temperature and Mass on the Strength of Heavy Element Signatures in Kilonovae
Authors: Tak Donggeun , Uhm Z. Lucas , Gillanders James H.
Published: May 2024

A kilonova, the electromagnetic emission produced by compact binary mergers, is formed through a delicate interplay of physical processes, involving r-process nucleosynthesis and interactions between heavy elements and photons through radiative transfer. This complexity makes it difficult to achieve a comprehensive understanding of kilonova spectra. In this study, we aim to enhance our understanding and establish connections between physical parameters and observables through radiative-transfer simulations. Specifically, we investigate how ejecta temperature and element mass influence the resulting kilonova spectrum. For each species, the strength of its line features depends on these parameters, leading to the formation of a distinct region in the parameter space, dubbed the resonance island, where the line signature of that species is notably evident in the kilonova spectrum. We explore its origin and applications. Among explored r-process elements (31 ≤ Z ≤ 92), we find that four species—SrII, YII, BaII, and CeII—exhibit large and strong resonance islands, suggesting their significant contributions to kilonova spectra at specific wavelengths. In addition, we discuss potential challenges and future perspectives in observable heavy elements and their masses in the context of the resonance island.
The Impact-driven Atmospheric Loss of Super-Earths around Different Spectral Types of Host Stars
Authors: Zhong Wei , Yu Cong , Jia Shi , Liu Shang-Fei
Published: May 2024

A planet’s mass loss is important for the its formation and evolution. The radius valley (RV) is believed to be triggered by evaporation-induced mass loss. As an alternative mechanism for RV, the mass loss of post-impact planets is thoroughly investigated in this work. The impact energy is converted to the planet’s internal energy, enhancing its core energy and accelerating mass loss and orbital migration. As the host star changes from K type to F type, the planet’s mass loss and orbital migration increase. When the initial gas-to-core-mass ratio is small, the migration efficiency for planets around K-type stars will increase, which helps to suppress mass loss and retain the planet’s mass and radius within a specific range. On the contrary, planets around more massive F-type stars experience more substantial mass loss, potentially leading to complete mass loss, and migrate to orbits with longer periods. Our calculation shows that planets around different spectral types of host stars give rise to an RV ranging from 1.3 to 2.0 R
⊕, consistent with the observed range of 1.3–2.6 R
⊕. Despite the presence of uncertain parameters, the planetesimal impact can promote the RV establishment for planets around host stars of different spectral types.
The Role of Stochastic Fermi-type Particle Acceleration in the Inner Jets of Active Galactic Nuclei
Authors: Wang Jieshuang , Rieger Frank M. , Mizuno Yosuke
Published: May 2024

High-resolution radio observations of nearby active galactic nuclei have revealed extended, limb-brightened structures in their inner jets. This ties in with other multiwavelength observations from radio to X-ray and gamma ray, indicating that a structured jet model is required. While electrons need to be kept energized to account for the observed features, the underlying particle acceleration mechanism is still unclear. We explore the role of stochastic Fermi-type particle acceleration, i.e., classical second-order Fermi and shear acceleration, for understanding the multiwavelength observations of the inner jets of M87. An analytical Fokker–Planck description is adopted to infer characteristic spectral indices and cutoff energies for these two mechanisms. We focus on electron synchrotron radiation as the dominant emission process. We find that the multiwavelength observations of M87 can be satisfactorily accounted for in a framework, where the X-rays are produced at a larger distance from the core than the radio emission region. This provides further support to multizone, broadband emission modeling. We use our findings to also comment on the acceleration of cosmic rays entrained in the sheath.

Iron line spectroscopy has been one of the leading methods not only for measuring the spins of accreting black holes but also for testing fundamental physics. Basing on such a method, we present an analysis of a data set observed simultaneously by NuSTAR and NICER for the black hole binary candidate MAXI J1803-298, which shows prominent relativistic reflection features. Various relxill_nk flavors are utilized to test the Kerr black hole hypothesis. The results obtained from our analysis provide stringent constraints on Johannsen deformation parameter α

Mass Ejection Driven by Sudden Energy Deposition in Stellar Envelopes
Authors: Corso Nicholas J. , Lai Dong
Published: May 2024

A number of stellar astrophysical phenomena, such as tidal novae and planetary engulfment, involve sudden injection of subbinding energy in a thin layer within the star, leading to mass ejection of the stellar envelope. We use a 1D hydrodynamical model to survey the stellar response and mass loss for various amounts (E
dep) and locations of the energy deposition. We find that the total mass ejection has a nontrivial dependence on E
dep due to the varying strengths of mass ejection events, which are associated with density/pressure waves breaking out from the stellar surface. The rapid occurrence of multiple breakouts may present a unique observational signature for sudden envelope heating events in stars.

Published: May 2024

We have discovered analytical expressions for the probability density function (PDF) of photons that are multiply scattered in relativistic flows, under the assumption of isotropic and inelastic scattering. These expressions characterize the collective dynamics of these photons, ranging from free-streaming to diffusion regions. The PDF, defined within the light cone to ensure the preservation of causality, is expressed in a three-dimensional space at a constant time surface. This expression is achieved by summing the PDFs of photons that have been scattered n times within four-dimensional space-time. We have confirmed that this formulation accurately reproduces the results of relativistic Monte Carlo simulations. We found that the PDF in three-dimensional space at a constant time surface can be represented in a separable variable form. We demonstrate the behavior of the PDF in the laboratory frame across a wide range of Lorentz factors for the relativistic flow. When the Lorentz factor of the fluid is low, the behavior of scattered photons evolves sequentially from free propagation to diffusion, and then to dynamic diffusion, where the mean effective velocity of the photons equates to that of the fluid. On the other hand, when the Lorentz factor is large, the behavior evolves from anisotropic ballistic motion, characterized by a mean effective velocity approaching the speed of light, to dynamic diffusion.

Eurocommunism: The rise and fall of a hopeful project
Authors: Donofrio Andrea
Published: May 2024

Eurocommunism at first seemed to offer a strategy for renewal, but by the mid-1980s its momentum had dissipated. Recent renewed interest in Eurocommunism is part of a wider reflection on the crisis of communism in all its variants since the last part of the twentieth century. Its
aim ‐ to forge a new strategy of democratic and peaceful conquest of political power, in keeping with the complexities of contemporary Western European societies ‐ at first seemed full of promise, but by the mid-1980s its momentum had dissipated. In spite of its aim of renewal,
it was followed by the crisis and decline of the main communist parties with which it was associated, the Italian Communist Party (PCI), the French Communist Party (PCF) and the Spanish Communist Party (PCE). The actions, decisions and strategies adopted by these parties can only be understood
if they are framed within the historical and geographical context of the 1970s ‐ a period of general crisis in both the capitalist and communist worlds, which ultimately consolidated a historical break between two different eras. The article discusses some of the key characteristics
of the project, and the hopes and disappointments it provoked, drawing widely on the published literature. It concludes with a brief engagement with some of the reflections and assessments that have been made on the subject. B roadly speaking, in the end Eurocommunism failed to find a way
of combining a reformist strategy with a revolutionary identity. It abandoned core aspects of its former strategy without finding a convincing replacement.
Interview with Nicos Poulantzas (April 1979)

Published: May 2024

Nicos Poulantzas talks to Stuart Hall and Alan Hunt New introduction by Dave Featherstone and Lazaros Karaliotas Nicos Poulantzas was one of the most influential figures in the renewal in European Marxism in the 1970s, and this interview shows some of the ways in which left
political discourse in Europe in the 1970s was shaped by widely shared trajectories and contexts. Poulantzas was a member of the Greek Communist Party of the Interior, which, like other parties moving towards a Eurocommunist position, had sought to articulate an alternative political strategy,
a different democratic imaginary, and a different road to power. Poulantzas makes a crucial distinction between right and left variants of Eurocommunism. The discussion of Poulantzas’s ideas on ‘authoritarian statism’ situate the interview within wider discussions and debates
during the 1970s about how to theorise and make sense of the relations between authoritarianism and the state; it is also part of a broader engagement with Poulantzas’s work that was central to Stuart Hall’s articulation of the concept of ‘authoritarian populism’, which
he used to signi ficant effect in his critical analysis of Thatcherism. In the concluding discussion Poulantzas is clearly straining against some of the limits of left organising ‐ in relation to discussions of feminism, the ‘ecological movement’ and other social movements.
But he also is clear that there will be no return to the certainties of a Leninist party model: ‘these are the problems which we must tackle; they will not go away, nor can we simply retreat to the old orthodoxy’. This effort to re-imagine the role of the centralising party while
also embracing a plurality of ‘autonomous social movements’ was an important unifying concern within some variants of Eurocommunism.

The issue of corporate mandatory standards in production improvement programmes
Authors: Linderson Sara , Eshetu Birkie Seyoum , Bellgran Monica
Published: May 2024

Purpose: This paper aims to explore and describe how companies manage the level of standardisation of improvement practices in a multisite context. It seeks to explain the managerial strategies applied to change the standardisation level in manufacturing companies with multiple production sites worldwide.Design/methodology/approach: This paper collects data through interviews, observations and company documents from a large multinational producing company and, specifically, from of the largest production sites in the company. The research design resembles a grounded theory approach by being reflexive and open to emerging themes. The standardisation strategy was analysed at a company that strived to increase the standardisation of problem-solving practices within about 20 production sites as part of their corporate lean programme.Findings: Several managerial tools were applied at the corporate level to increase the standardisation level of problem-solving practices, such as developing standards and a company-specific toolbox aligned with an in-house maturity model. In addition, deploying change leaders and global implementation targets enabled audits and progress. However, consequences at the production-site level became minor adaptations of standards, the design of training models as a "roll-out", and a resource-demanding implementation process.Originality/Value: This paper empirically demonstrates strategic tools that corporate management teams apply to influence the company's standardisation level of practices. The study describes the purpose and consequences of the design of the toolbox, maturity model, training model, and implementation targets, which aims to simplify the complex task of managing standardisation in a corporate group. By applying a knowledge-based view, four processes (i.e. adaptation, integration, upskilling, and learning) were identified to improve the management strategies in multisite contexts.

Influence of VR-Assisted College Dance on College Students' Physical and Mental Health and Comprehensive Quality
Authors: Zhao Ziwan
Published: May 2024

With the development and the popularization of sports dance, sports dance teaching has become a required elective course in universities. Sports dance can not only improve students' comprehensive quality, but also affect college students' healthy psychology. The use of VR (Virtual Reality) technology in dance education will definitely develop and promote dance education. This paper studies an effective feature extraction method for the characteristics of dance movements based on VR. The edge features of all video images in each segment are accumulated into one image, and the directional gradient histogram features are extracted from it. The results show that compared with the current robust regression method and cascade regression method, our method has higher positioning accuracy on the pollution test set, and more than 75% of the sample errors in this method are within 0.1. This also verifies the effectiveness of this motion recognition algorithm for dance motion recognition. Dance can effectively resist the psychological barriers of college students and improve their comprehensive quality.

The rare hemorrhagic disorder known as acquired hemophilia A (AHA) is brought on by the spontaneous development of autoantibodies against coagulation factor VIII (FVIII). It may be secondary to autoimmune diseases or cancers, or it may be idiopathic. Less than 10% of cases may have an infection as a secondary cause. We present the case of a 90-year-old anemic woman who was admitted to the hospital. She contracted a urinary tract infection (UTI) while in the hospital, and her urine took on a distinct purple hue. She had poor hemorrhagic manifestations and a prolonged partial thromboplastin time. After ruling out autoimmune and neoplastic causes, we diagnosed AHA as a result of a UTI caused by Enterococcus faecalis.

Published: May 2024

Objective:

To evaluate and compare the effect of “super” high-frequency (SHF; >130 Hz) stimulation and conventional high-frequency (CHF; 100–130 Hz) stimulation on patients with dyskinesia.

Methods:

The patients were evaluated using the Abnormal Involuntary Movement Scale (AIMS) with SHF and CHF after levodopa infusion. The secondary outcomes included the Burke–Fahn–Marsden dystonia rating scale and the Unified Parkinson’s Disease Rating Scale part III scores.

Result:

Six patients were enrolled in this study. The AIMS scores were not significantly different between SHF and CHF (p=0.89, paired t-test). Three out of six patients (50%) had better AIMS scores when SHF was applied, the scores of two patients remained unchanged, and one patient had a score worse than that with CHF. No short-term adverse effects were observed.

Conclusion:

The results of our pilot study show that SHF is safe and tolerable. We believe that in appropriate cases SHF can be used for managing dyskinesia after conventional methods yield unfavorable results.

Published: May 2024

Infectious diseases are common in tropical countries, and varied complications associated with such diseases are frequently encountered. Movement disorders are a complication of infectious diseases, and the spectrum of movement disorders differs between tropical countries and other countries. We screened three electronic databases for cases of dystonia presenting as a manifestation of infections diseases and selected cases and series describing chorea associated with infections. The studies were identified and data regarding the study design, sample size, neurological assessment, and diagnostic workup, including brain imaging and cerebrospinal fluid analysis were extracted. After a detailed review of 139 selected articles, 39 articles were referred to in the final manuscript of this narrative review. Dystonia is most commonly associated with Japanese encephalitis than other central nervous system infections. The hypothesized mechanisms of infection-related dystonia are vasculopathy, space-occupying lesions, autoimmune reactions, inflammation, or via anti-dopaminergic drug therapy. The infections presenting with dystonia include tuberculosis, Japanese encephalitis, streptococcal infections, varicella-zoster virus, subacute sclerosing panencephalitis, dengue, and neurocysticercosis. In this narrative review, we discuss the different types of central nervous system infections that present with dystonia.

Authors: Patel Khushboo , Vijayaraghavan Asish , Krishnan Syam , Puthenveedu Divya K. , Cherian Ajith
Published: May 2024

Hemifacial spasm is a common peripheral movement disorder that usually results from neurovascular conflict involving the facial nerve motor root exit zone. Although it is a sporadic disease, some cases of familial clustering have been reported. In this case report, we present a case of familial occurrence of hemifacial spasm with dolichoectasia of the vertebrobasilar system in three siblings. The patients responded well to botulinum toxin therapy. A genetic mechanism predisposing them to vascular abnormalities is likely to be responsible for the clinical–radiological picture in our patients.

Published: May 2024

Introduction:

Middle latency auditory evoked potentials (MLAEPs) allow the assessment of the function of the central part of the auditory pathway. MLAEP abnormalities have been demonstrated in patients with Alzheimer’s and Parkinson’s disease with dementia.

Objective:

The objective of our study was to assess the MLAEP findings in patients with idiopathic Parkinson’s disease (IPD) and atypical parkinsonism (AP) and to determine whether MLAEPs could contribute to the differential diagnosis of IPD and AP.

Methods:

We included 75 participants (25 IPD patients, 25 AP, and 25 age-matched healthy control subjects). MLAEPs were recorded in all patients and control subjects as per the standard procedure for MLAEP recordings. Absent waveforms (Na and Pa waves) and prolonged latencies of individual waves were considered as abnormal MLAEP readings.

Results:

The Pb waveform was significantly absent in the patients with IPD and AP compared to control subjects (p = 0.02). The Pb waveform was significantly absent in the AP group compared to the IPD group (p = 0.03). The Pb waveform was significantly absent in the AP group without cognitive impairment compared to the IPD group without cognitive impairment (p = 0.003). There was no statistically significant difference between the patients with IPD with and without cognitive impairment (p = 0.07). There was no significant difference among the groups with respect to Na and Pa wave latencies. Other parameters such as Na–Pa amplitude and Nb–Pb amplitudes were not significant among the groups.

Conclusion:

The absence of Pb potential in AP is an electrophysiological clue for the diagnosis of AP in patients presenting with parkinsonism. MLAEPs can act as an electrophysiological adjunct to the clinical imaging markers in differentiating IPD from AP.

Hypomyelinating leukodystrophies (HLDs) are a heterogeneous group of disorders caused by primary deficit in myelin development; they are radiologically characterized by mild T2 hyperintensity with near normal T1 signal of the cerebral white matter. While most HLDs occur during infancy or childhood, adult-onset phenotypes are reported as well. To date, HLDs have not been extensively discussed in the literature on movement disorders apart from segregated case reports. From the perspective of movement disorders, HLDs commonly manifest as spastic ataxia, except for disorders such as hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC) and fucosidosis, where dystonia predominates. In addition, dystonia can be associated with the 18q deletion syndrome and KIF1C- and NKX6-2-related spastic ataxia. Chorea can be observed in the striatal variant of POLR3A, 18q deletion syndrome, and KIF1C-related disorders. Associated morphological features such as facial dysmorphism, hypodontia, early cataract, and skeletal and limb dysmorphism often provide vital clues to recognize these HLDs. Additional imaging clues include striatal atrophy in the H-ABC syndrome, spinal cord T2 hyperintensities in leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation, intracranial calcification in Cockayne syndrome, and pallidal T2 hypointensity in fucosidosis. Early recognition of these clinicoradiological clues will be helpful in ordering a comprehensive genetic panel to confirm the diagnosis and determine the prognosis and therapeutic outcome.

Published: May 2024

Tardive dystonia (TD) is a disabling neurological disorder and is usually refractory to medical therapy. Over the past decade, several case reports and case series have demonstrated remarkable benefits of deep brain stimulation of the globus pallidus interna for the treatment of refractory TD. In this case report, we present an illustrative case of refractory TD treated with globus pallidus interna–deep brain stimulation, with long-term sustained improvement of the dystonia and psychiatric comorbidity. In addition, the patient had a dorsal cord schwannoma, producing pyramidal signs in the lower limbs, which highlights the need for meticulous clinical examination for optimum patient management.
Levosulpiride-induced arm-raising stereotypy in a 65-year-old man
Authors: Agarwal Pankaj A. , Lalkaka Jimmy A.
Published: May 2024

A 65-year-old man presented to us with a 6-month history of recurrent, bilateral, purposeless, arm-raising and lowering movements that fulfilled all criteria for stereotypy. He was on a dopamine blocking agent levosulpiride before the onset of the movements. After the diagnosis of tardive, levosulpiride-induced, armraising stereotypy was made, the offending drug was stopped. Tetrabenazine at 100 mg/day produced near-complete improvement at 3 months. Proximal limb involvement—such as arm-raising—is not reported as a phenotype in tardive stereotypy to date, with all cases having distal hand involvement. Furthermore, any limb stereotypy is not reported with levosupride to date.

BACKGROUND AND AIM:

Clinical services were severely affected globally during the COVID-19 pandemic. This study aimed to characterize the clinical experience of using botulinum toxin (BTX) injections during the COVID-19 pandemic.

METHODS:

This is a retrospective chart review of patients who received BTX injections from April 2019 to January 2022.

RESULTS:

A total of 105 patients received an BTX injections, out of which 76 (72.4%) were men. The mean age of the patients was 47.9 ± 15.1 years. The most common indication for receiving BTX injections was dystonia (n = 79; 75.2%), followed by hemifacial spasm (n = 22; 21%) and miscellaneous movement disorders (n = 4; 3.8%). Focal dystonia (n = 45; 57%) was the most frequent form of dystonia, followed by segmental dystonia (n = 24; 30%). The percentage of generalized dystonia and hemidystonia was 12% and 1%, respectively. Cervical dystonia (44.4%), blepharospasm (17.8%), and writer’s cramp (15.6%) were the most frequent forms of focal dystonia. The miscellaneous group included four patients (3.8%) with trigeminal neuralgia, Holmes tremor, dystonic tics, and hemimasticatory spasm. The mean ages of patients in the dystonia, hemifacial spasm, and the miscellaneous groups were 47.7 ± 14.9 years, 49.2 ± 14.0 years, and 44.2 ± 26.0 years, respectively. The mean BTX dose was 131.6 ± 104.1 U. The mean BTX doses for the dystonia group, hemifacial spasm, and the miscellaneous group were 158.7 ± 105.3 U, 40.1 ± 11.3 U, and 100.0 ± 70.7 U, respectively.

CONCLUSION:

Most patients in our cohort had dystonia, followed by hemifacial spasm. Among the patients with dystonia, most had focal dystonia, with cervical dystonia being the most common movement disorder. The data obtained in our study is important to increase awareness of the effectiveness of BTX injections in patients with chronic disorders.
