description: Background: The impact of tele-education for movement disorders on medical students is unknown. The present study had three objectives. First, to create a tele-education program for medical students in regions with limited access to movement disorders curricula. Second, to analyze the feasibility, satisfaction, and improvement of medical knowledge. Third, to assess the main reasons of medical students for attending this course. Methods: In 2016, a program was piloted in a low-middle income (Cameroon) and a middle-high income (Argentina) country. Medical students were offered a free movement disorder tele-education program (four medical schools in Argentina, and 1 medical school in Cameroon). Six real-time videoconferences covering hyperkinetic and hypokinetic movement disorders were included. Evaluations included attendance, pre- and post-medical knowledge, and satisfaction questionnaires. Results: The study included 151 undergraduate medical students (79.4% from Argentina, 20.6% from Cameroon). Feasibility was acceptable with 100% and 85.7% of the videoconferences completed in Argentina and Cameroon, respectively. Attendance was higher in Argentina compared to Cameroon (75% vs. 33.1%). According to student reports, the topics and innovative educational environment were the main reasons for attendance. Both groups ranked satisfaction as moderate to high, and medical knowledge improved similarly in both countries. Discussion: Tele-education can improve movement disorders knowledge in medical schools in high-middle and low-middle income countries lacking access to other educational opportunities.

description: Motivated by a possible convergence of terrestrial limbless locomotion strategies ultimately determined by interfacial effects, we show how both 3D gait alterations and locomotory adaptations to heterogeneous terrains can be understood through the lens of local friction modulation. Via an `everything-is-friction' modeling approach, compounded by 3D simulations, the emergence and disappearance of a range of locomotory behaviors observed in nature is systematically explained in relation to inhabited environments. Our approach also simplifies the treatment of terrain heterogeneity, whereby even solid obstacles may be seen as high friction regions, which we confirm against experiments of snakes `diffracting' while traversing rows of posts [1], similar to optical waves. We further this optic analogy by illustrating snake refraction, reflection and lens focusing. We use these insights to engineer surface friction patterns and demonstrate passive snake navigation in complex topographies. Overall, our study outlines a unified view that connects active and passive 3D mechanics with heterogeneous interfacial effects to explain a broad set of biological observations, and potentially inspire engineering design.

description: Poverty is ubiquitous in the nook and corner of the globe despite the efforts of international agencies including the UN to offset the issues pertaining to it. The challenges are increasing day by day. The Millennium Development Goals (MDGs) hence highlighted poverty eradication as one of its main mottos. The UN World Tourism Organization (UNWTO), the apex body of tourism development also advocated the MDGs and quoted Tourism as a 'War on Poverty'. Since then, Tourism has been widely considered as a tool for poverty eradication and economic equity. Tourism as a capitalist sector and also a threat to the indigenous cultures and economy of the third world countries. Many a debate on the theme point out that the influences of tourism on mitigating poverty are just superfluous. This paper is an attempt to highlight and analyse the discourses existing in the theoretical frameworks of tourism's role in poverty elimination. This paper will also attempt to envisage channels for ideally bridging the contrasting points present in the theories.

description: Sgr A* is considered to be a massive black hole at the Galactic center and is known to be variable in radio, millimeter, near-IR and X-rays. Recent multi-wavelength observing campaigns show a simultaneous X-ray and near-IR flare, as well as sub-millimeter and near-IR flares from Sgr A*. The flare activity is thought to be arising from the innermost region of Sgr A*. We have recently argued that the duration of flares in near-IR and submillimeter wavelengths implies that the burst of emission expands and cools on a dynamical time scale before the flares leave Sgr A*. The detection of radio flares with a time delay in the range of 20 and 40 minutes between 7 and 12mm peak emission implies adiabatic expansion of a uniform, spherical hot blob due to flare activity. We suspect that this simple outflow picture shows some of the characteristics that are known to take place in microquasars, thus we may learn much from comparative study of Sgr A* and its environment vs. microquasars.

description: Background: Writer’s cramp (WC) is one of the commonly observed focal dystonias. The pathophysiology of WC has not been fully understood. The role of the cerebellum has been increasingly recognized in the pathogenesis of dystonia. As the cerebellum is crucial for maintaining accurate eye–hand coordination (EHC), its role in the pathogenesis of WC can be investigated by studying the EHC in patients with WC. Methods: Fifteen patients with WC (women:men, 3:12) and 15 age- and gender-matched controls performed oculomotor and EHC tasks. A visually guided stimulus (VGS) task was first performed with eye-only condition (EOC) and then with EHC. Results: A significant interaction between the groups (controls and patients) and tasks (EOC and EHC) with age as a covariate confirmed that the two groups reacted differently to the tasks in saccadic latency (F(1,27) = 4.8; p = 0.039) and average saccade acceleration (F(1,27) = 10.6; p = 0.003). The curvature index of acceleration of the hand was significantly more in patients compared to controls (patients vs. controls, 2.4±0.4 vs. 1.8±0.2, p = 0.01). While performing the EHC task, there was a significant correlation of the Writer’s Cramp Rating Score with the average saccadic speed (–0.61, p = 0.016), peak saccadic deceleration (0.59, p = 0.019) and average saccadic acceleration (–0.63, p = 0.012). Discussion: Saccadic acceleration and latency are abnormal while performing EHC tasks in patients with WC. Our study gives further insights into the possible role of the cerebellum in the pathogenesis of WC.

description: Background: Postural tremor can sometimes occur in spinocerebellar ataxias (SCAs). However, the prevalence and clinical characteristics of postural tremor in SCAs are poorly understood, and whether SCA patients with postural tremor have different ataxia progression is not known. Methods: We studied postural tremor in 315 patients with SCA1, 2, 3, and 6 recruited from the Clinical Research Consortium for Spinocerebellar Ataxias (CRC-SCA), which consists of 12 participating centers in the United States, and we evaluated ataxia progression in these patients from January 2010 to August 2012. Results: Among 315 SCA patients, postural tremor was most common in SCA2 patients (SCA1, 5.8%; SCA2, 27.5%; SCA3, 12.4%; SCA6, 16.9%; p = 0.007). SCA3 patients with postural tremor had longer CAG repeat expansions than SCA3 patients without postural tremor (73.67 ± 3.12 vs. 70.42 ± 3.96, p = 0.003). Interestingly, SCA1 and SCA6 patients with postural tremor had a slower rate of ataxia progression (SCA1, β = –0.91, p < 0.001; SCA6, β = –1.28, p = 0.025), while SCA2 patients with postural tremor had a faster rate of ataxia progression (β = 1.54, p = 0.034). We also found that the presence of postural tremor in SCA2 patients could be influenced by repeat expansions of ATXN1 (β = –1.53, p = 0.037) and ATXN3 (β = 0.57, p = 0.018), whereas postural tremor in SCA3 was associated with repeat lengths in TBP (β = 0.63, p = 0.041) and PPP2R2B (β = –0.40, p = 0.032). Discussion: Postural tremor could be a clinical feature of SCAs, and the presence of postural tremor could be associated with different rates of ataxia progression. Genetic interactions between ataxia genes might influence the brain circuitry and thus affect the clinical presentation of postural tremor.

description: Psychodermatologic disorders consist a great part of psychosomatic disorders with psoriasis one of the main representatives. The aim of the study is the investigation and analysis of the iteraction among parameters of the psyche, the neuroendocrine and immune systems ata psoriatics. 24 psoriatic patients and the same number of healthy volunteers participated in the study. They were administered psychometric questionnaires for depression(BDI), anxiety(STAI), symptom checklist+(SCL-90R) Holmes-Rahe social readjustment rating scale. Both of the grower underwent CRH test and dexamethasone suppression test. Immune phenotype of Lymphocytes' subpopulations were estimated as well. The psychometric inventories revealed significantly more depressive and anxiety mood in psoriatircs. As far as the anxiety feature is concerned, it mostly seems to be result of a reaction to stressful life events than a certain personality trait among psoriatics. As far as the neuroendocrine aspect is concerned, although in general there were no significantly different results in CRH test between the two groups, there is evidence for blunted responsiveness of HPA axis in psoriasis. There were activation of T Lymphocytes and increase of circulating CD 8+ cells in psoriatic group. There was no clear correlation among psychometric, neuroendocrine and immune parametres among psoriatics

description: We present the Time Lag/Delay Reconstructor (TLDR), an algorithm for reconstructing velocity delay maps in the Maximum A Posteriori framework for reverberation mapping. Reverberation mapping is a tomographical method for studying the kinematics and geometry of the broad-line region of active galactic nuclei at high spatial resolution. Leveraging modern image reconstruction techniques, including Total Variation and Compressed Sensing, TLDR applies multiple regularization schemes to re-construct velocity delay maps using the Alternating Direction Method of Multipliers. Along with the detailed description of the TLDR algorithm we present test reconstructions from TLDR applied to synthetic reverberation mapping spectra as well as a preliminary reconstruction of the H\b{eta}feature of Arp 151 from the 2008 Lick Active Galactic Nuclei Monitoring Project.

description: Background: Involvement of the central nervous system in patients with syphilis (neurosyphilis) may result in several neuropsychiatric symptoms. Rarely, patients with neurosyphillis may develop movement disorders with different phenomenology. Subtle orofacial dyskinesias have been reported in patients with neurosyphilis, known as the candy sign. Case Report: We describe a patient with neurosyphilis who presented with severe orofacial involuntary movements. Discussion: Our patient had orofacial movements at presentation and severity of the movements was much higher than the candy sign that has been reported in patients with neurosyphilis. This report contributes towards the ever-expanding clinical spectrum of neurosyphilis.

description: A new cosmological variable is introduced which characterizes the degree of departure from Einstein's General Relativity (GR) with a cosmological constant. The new parameter, \varpi, is the cosmological analog of γ, the parametrized post-Newtonian variable which measures the amount of spacetime curvature per unit mass. In the cosmological context, \varpi measures the difference between the Newtonian and longitudinal potentials in response to the same matter sources, as occurs in certain scalar-tensor theories of gravity. Equivalently, \varpi measures the scalar shear fluctuation in a dark energy component. In the context of a "vanilla" LCDM background cosmology, a non-zero \varpi signals a departure from GR or a fluctuating cosmological constant. Using a phenomenological model for the time evolution \varpi=\varpi_0 ρ_{DE}/ρ_{M} which depends on the ratio of energy density in the cosmological constant to the matter density at each epoch, it is shown that the observed cosmic microwave background (CMB) temperature anisotropies limit the overall normalization constant to be -0.4 < \varpi_0 < 0.1 at the 95% confidence level. Existing measurements of the cross-correlations of the CMB with large-scale structure further limit \varpi_0 > -0.2 at the 95% CL. In the future, integrated Sachs-Wolfe and weak lensing measurements can more tightly constrain \varpi_0, providing a valuable clue to the nature of dark energy and the validity of GR.

The role of the abdominal muscles in breathing

Publisher: name: University of British Columbia
Year: 2011

description: Nine tracheotomized dogs were chronically instrumented with sonomicrometer length measurement transducers and fine wire EMG electrodes in each of the four abdominal muscles: transversus abdominis (TA), internal oblique (IO), external oblique (EO) and rectus abdominis (RA). To assess the effects of anesthesia and chronic implantation of transducers on abdominal muscle resting length and length changes, muscle length measurements were made in the anesthetized dogs and then repeated in the same dogs when awake, on successive days over periods ranging from two to eight weeks. Over the duration of the study periods the awake dogs were also exposed to different experimental protocols. The experimental protocols were postural changes, expiratory threshold loading (ETL) and CO₂ rebreathing, and ETL and CO₂ rebreathing before and after reversible vagal blockade. The objectives were to determine individual abdominal muscle tonic and phasic, expiratory shortening in response to these different stimuli. We hypothesized that the individual abdominal muscles would exhibit differing amounts of tonic and phasic activity and that the internal muscle layer (TA and IO) would be recruited preferentially compared to the external muscle layer (EO and RA) in response to each of the stimuli. To assess the relative importance of vagally-mediated reflexes in the control of abdominal muscle activation, the awake dogs were exposed to ETL and progressive hypercapnia before and after reversible vagal blockade. The results of these studies demonstrate the feasibility of using chronically implanted sonomicrometer transducers for measurement of abdominal muscle length changes in awake dogs. Phasic expiratory shortening of the TA, IO and EO was increased by changes in posture from the lateral decubitis to the sitting and standing positions, by ETL and by hypercapnia. Tonic shortening of the TA and/or the IO was also present under all three conditions. There was preferential recruitment of the internal muscles under all three conditions and this preferential recruitment persisted during ETL and CO₂ rebreathing after vagal blockade. We conclude that abdominal muscle activity is mediated by vagal and chemical reflexes and that segmental reflexes from muscle proprioceptors play a role in modulating the level of individual abdominal muscle activity.

description: Responsible tourism is emerging out as a tourism strategy that focuses on the maximization of tourism benefits. It not only emphasizes on the environmental protection but also remembers the tourism stakeholders their socio-economic and environmental responsibilities to a certain place and to its people. In this background, the current paper has tried to access two Community Based Tourism (CBT) initiatives namely (1) Sundarban Jungle Camp, and (2) Tora Eco resort and Life Experience Centre in the Bali village of Indian Sunderbans –those have been emerged as two successful Responsible Tourism Models and have immense contribution towards the sustainable rural development of Bali village, Indian Sunderbans and are also inspiring others to follow their footprints. The researchers have adopted the qualitative approach for collecting the empirics of the paper. Both primary and secondary data have been collected to provide evidences to support the concluding remark that these two Community Based Tourism initiatives those are following the Responsible Tourism Guidelines have significant contribution towards achieving the economic prosperity, social equity and environmental quality - the three pillars of sustainable development in the context of Bali village. Therefore, the researchers suggest that more and more such responsible community based tourism initiatives should be carried out in the future course of time in different parts of Sunderbans also, for achieving the same success in a larger scale.
Is there a Premotor Phase of Essential Tremor?

description: Background: Essential tremor (ET) is the most common tremor disorder. In addition to its hallmark feature, kinetic tremor of the upper limbs, patients may have a number of non-motor symptoms and signs (NMS). Several lines of evidence suggest that ET is a neurodegenerative disorder and certain NMS may antedate the onset of tremor. This article comprehensively reviews the evidence for the existence of a “premotor phase” of ET, and discusses plausible biological explanations and implications. Methods: A PubMed search in May 2017 identified articles for this review. Results: The existence of a premotor phase of ET gains support primarily from longitudinal data. In individuals who develop incident ET, baseline (i.e., premotor) evaluations reveal greater cognitive dysfunction, a faster rate of cognitive decline, and the presence of a protective effect of education against dementia. In addition, baseline evaluations also reveal more self-reported depression, antidepressant medication use, and shorter sleep duration in individuals who eventually develop incident ET. In cross-sectional studies, certain personality traits and NMS (e.g., olfactory dysfunction) also suggest the existence of a premotor phase. Discussion: There is preliminary evidence supporting the existence of a premotor phase of ET. The mechanisms are unclear; however, the presence of Lewy bodies in some ET brains in autopsy studies and involvement of multiple neural networks in ET as evident from the neuroimaging studies, are possible contributors. Most evidence is from a longitudinal cohort (Neurological Disorders of Central Spain: NEDICES); additional longitudinal studies are warranted to gain better insights into the premotor phase of ET.

description: Heritage Tourism has emerged as a catalyst for economic growth thanks to its ability to create alternative jobs, induce developed infrastructures and increase the flow of both domestic and foreign tourists which result in regional as well as national growth. India, a country blessed with remarkable natural and manmade heritages has welcomed this niche form tourism with open arms. However, as a consequence of negligence and lack of proper management skills, the sustainability of these monuments is at cross roads. Improper heritage-awareness, lack of coordination among the stakeholders, inadequate funding as well paucity in understanding the growing demands have further contributed to the sad state. Therefore, conservation, preservation, sustainability and enhancement of these heritages remain the top most priority of the country. Based on the experiences of NGOs and review of major works in the area of heritage management and conservation, this paper puts light on the overall status of heritage sites and monuments in India and also tries to find out the emerging challenges in heritage preservation in this country. Moreover, this paper outlines major strategic mechanisms required to overcome these constraints to preserve our cultural heritages which are nothing but the true reflection of our rich cultural past.

description: Most supervised machine learning tasks are subject to irreducible prediction errors. Probabilistic predictive models address this limitation by providing probability distributions that represent a belief over plausible targets, rather than point estimates. Such models can be a valuable tool in decision-making under uncertainty, provided that the model output is meaningful and interpretable. Calibrated models guarantee that the probabilistic predictions are neither over- nor under-confident. In the machine learning literature, different measures and statistical tests have been proposed and studied for evaluating the calibration of classification models. For regression problems, however, research has been focused on a weaker condition of calibration based on predicted quantiles for real-valued targets. In this paper, we propose the first framework that unifies calibration evaluation and tests for general probabilistic predictive models. It applies to any such model, including classification and regression models of arbitrary dimension. Furthermore, the framework generalizes existing measures and provides a more intuitive reformulation of a recently proposed framework for calibration in multi-class classification. In particular, we reformulate and generalize the kernel calibration error, its estimators, and hypothesis tests using scalar-valued kernels, and evaluate the calibration of real-valued regression problems.

description: Magnetic microscopy that combines nanoscale spatial resolution with picosecond scale temporal resolution uniquely enables direct observation of the spatiotemporal magnetic phenomena that are relevant to future high-speed, high-density magnetic storage and logic technologies. Magnetic microscopes that combine these metrics has been limited to facility-level instruments. To address this gap in lab-accessible spatiotemporal imaging, we develop a time-resolved near-field magnetic microscope based on magneto-thermal interactions. We demonstrate both magnetization and current density imaging modalities, each with spatial resolution that far surpasses the optical diffraction limit. In addition, we study the near-field and time-resolved characteristics of our signal and find that our instrument possesses a spatial resolution on the scale of 100 nm and a temporal resolution below 100 ps. Our results demonstrate an accessible and comparatively low-cost approach to nanoscale spatiotemporal magnetic microscopy in a table-top form to aid the science and technology of dynamic magnetic devices with complex spin textures.

description: The waste water containing synthetic organic dyes is commonly carcinogenic to the physical health of humans and wildlife. Solid-extraction is considered to be one of the most effective technologies in the removal of these synthetic organic dyes from the water. In this paper, the Al-BTB is synthesized and first applied in the removal of eight synthetic dyes including malachite green, basic fuchsin, acid black 210, Congo red, direct black 19, rhodamine B, direct blue 15 and methyl orange. Interestingly, the as-synthesized Al-BTB represents the highly efficient adsorption capacities toward these organics at a rapid rate. The adsorption conditions including the pH, adsorption time and the dye’s concentrations were optimized, and adsorption behaviors were explored through the adsorption kinetics simulation and the adsorption isotherm analyses. It is worth noting that the resulting Al-BTB is mesoporous and represents prominent adsorption efficiency at rapid rates toward eight dyes despite its cationic or anionic nature and with different functional groups. The reusability of the Al-BTB is also investigated, and the adsorption mechanism is discussed. This work enriches the prospective applications of mesoporous MOFs in the efficient removal of the organic dyes from waste water.

description: Clinical Vignette: A 64-year-old male with a history of essential tremor with bilateral thalamic ventralis intermedius deep brain stimulation implants had elevated therapeutic impedance values despite normal lead integrity impedances and good response to stimulation. Clinical Dilemma: Do elevated therapeutic impedance values indicate a sign of hardware malfunction? What are the guidelines to approach deep brain stimulation hardware malfunction? Clinical Solution: Lead integrity impedance values are a better evaluation of hardware integrity. The discrepancy between therapeutic and lead-integrity impedance values can arise when using low voltage settings. Gaps in Knowledge: There are no established guidelines for the management of possible hardware malfunction in deep brain stimulation. The recommended approach is to distinguish between open and short circuit problems followed by an “inching” evaluation, assessing the structures from the implantable and programmable generator to the intracranial leads. Constant-current devices will deliver a more stable stimulation but the effect of their adoption is still not clear. Expert Commentary: This case emphasizes the need for clinicians to understand fundamental differences in lead integrity and therapeutic impedance while utilizing a methodical approach in treating hardware malfunction. It highlights future avenues of investigation regarding the utility of constant current DBS technology.

Olympic Gels: Concatenation and Swelling

description: Concatenation and equilibrium swelling of Olympic gels, which are composed of entangled cyclic polymers, is studied by Monte Carlo Simulations. The average number of concatenated molecules per cyclic polymers, $f_n$, is found to depend on the degree of polymerization, $N$, and polymer volume fraction at network preparation, $ϕ_0$, as $f_n ~ ϕ_0^{ν/(3ν-1)}N$ with scaling exponent $ν = 0.588$. In contrast to chemically cross-linked polymer networks, we observe that Olympic gels made of longer cyclic chains exhibit a smaller equilibrium swelling degree, $Q ~ N^{-0.28} ϕ_0^{-0.72}$, at the same polymer volume fraction $ϕ_0$. This observation is explained by a desinterspersion process of overlapping non-concatenated rings upon swelling, which is tested directly by analyzing the change in overlap of the molecules upon swelling.

description: The relation between the Evershed flow and moving magnetic features (MMFs) is studied using high-cadence, simultaneous spectropolarimetric measurements of a sunspot in visible (630.2 nm) and near-infrared (1565 nm) lines. Doppler velocities, magnetograms, and total linear polarization maps are calculated from the observed Stokes profiles. We follow the temporal evolution of two Evershed clouds that move radially outward along the same penumbral filament. Eventually, the clouds cross the visible border of the spot and enter the moat region, where they become MMFs. The flux patch farther from the sunspot has the same polarity of the spot, while the MMF closer to it has opposite polarity and exhibits abnormal circular polarization profiles. Our results provide strong evidence that at least some MMFs are the continuation of the penumbral Evershed flow into the moat. This, in turn, suggests that MMFs are magnetically connected to sunspots.

description: When they are damaged or injured, soft biological tissues are able to self-repair and heal. Mechanics is critical during the healing process, as the damaged extracellular matrix (ECM) tends to be replaced with a new undamaged ECM supporting homeostatic stresses. Computational modeling has been commonly used to simulate the healing process. However, there is a pressing need to have a unified thermodynamics theory for healing. From the viewpoint of continuum damage mechanics, some key parameters related to healing processes, for instance, the volume fraction of newly grown soft tissue and the growth deformation, can be regarded as internal variables and have related evolution equations. This paper is aiming to establish this unified framework inspired by thermodynamics for continuum damage models for the healing of soft biological tissues. The significant advantage of the proposed model is that no \textit{ad hoc} equations are required for describing the healing process. Therefore, this new model is more concise and offers a universal approach to simulate the healing process. Three numerical examples are provided to demonstrate the effectiveness of the proposed model, which is in good agreement with the existing works, including an application for balloon angioplasty in an arteriosclerotic artery with a fiber cap.

description: In earlier work we showed how the low energy behavior of the symmetric Anderson model in a magnetic field $H$ could be described in terms of field dependent renormalized quasiparticles. Here we extend the approach to the non-symmetric Anderson impurity model and to the infinite dimensional Hubbard model within the DMFT approach. We present NRG results for the local spectral densities and the local longitudinal and transverse dynamic spin susceptibilities for the different parameter regimes and a sequence of values of the magnetic field. We calculate the renormalized parameters for the quasiparticles. Away from half-filling we find quasiparticle weights, $z_σ(H)$, which differ according to the spin type $σ=\uparrow$ or $σ=\downarrow$. Using the renormalized perturbation theory, we show that the low energy features in the NRG results can be well described in the metallic phase in terms of these field dependent parameters. We also check Luttinger's theorem for the Hubbard model and find it to be satisfied in all parameter regimes and for all values of the magnetic field.

description: This article extends the solution proposed by Aït-Sahalia, Fan, and Li for the leverage effect puzzle, which refers to a fact that empirical correlation between daily asset returns and the changes of daily volatility estimated from high frequency data is nearly zero. Complementing the analysis in Aït-Sahalia, Fan, and Li via the Heston model, we work with a generic semi-nonparametric stochastic volatility model via an operator-based expansion method. Under such a general setup, we identify a new source of bias due to the flexibility of variance dynamics, distinguishing the leverage effect parameter from the instantaneous correlation parameter. For estimating the leverage effect parameter, we show that the main results on analyzing the various sources of biases as well as the resulting statistical procedures for biases correction in Aït-Sahalia, Fan, and Li hold true and are thus indeed theoretically robust. For estimating the instantaneous correlation parameter, we developed a new nonparametric estimation method.

description: We present a novel ultrastable superconducting radio-frequency (RF) ion trap realized as a combination of an RF cavity and a linear Paul trap. Its RF quadrupole mode at 34.52 MHz reaches a quality factor of $Q\approx2.3\times 10^5$ at a temperature of 4.1 K and is used to radially confine ions in an ultralow-noise pseudopotential. This concept is expected to strongly suppress motional heating rates and related frequency shifts which limit the ultimate accuracy achieved in advanced ion traps for frequency metrology. Running with its low-vibration cryogenic cooling system, electron beam ion trap and deceleration beamline supplying highly charged ions (HCI), the superconducting trap offers ideal conditions for optical frequency metrology with ionic species. We report its proof-of-principle operation as a quadrupole mass filter with HCI, and trapping of Doppler-cooled ${}^9\text{Be}^+$ Coulomb crystals.
