description: We compute dilepton production from the deconfined phase of the quark-gluon plasma using leading-order (3+1)-dimensional anisotropic hydrodynamics. The anisotropic hydrodynamics equa- tions employed describe the full spatiotemporal evolution of the transverse temperature, spheroidal momentum-space anisotropy parameter, and the associated three-dimensional collective flow of the matter. The momentum-space anisotropy is also taken into account in the computation of the dilepton production rate, allowing for a self-consistent description of dilepton production from the quark-gluon plasma. For our final results, we present predictions for high-energy dilepton yields as a function of invariant mass, transverse momentum, and pair rapidity. We demonstrate that high- energy dilepton production is extremely sensitive to the assumed level of initial momentum-space anisotropy of the quark-gluon plasma. As a result, it may be possible to experimentally constrain the early-time momentum-space anisotropy of the quark-gluon plasma generated in relativistic heavy ion collisions using high-energy dilepton yields.

description: This study explains the well-structured development and validation of the HPTLC method and the qualitative evaluation of Evogliptin in both bulk and tablet formulation using the quality by design (QbD) approach. Chromatographic separation was carried out on an aluminium-backed silica gel F254 plate using a mobile phase consisting of ethyl acetate :methanol: triethylamine (6:4:0.1 V/V/V). Densitometry was carried out at a wavelength of 267 nm. The band corresponding to the Evogliptin was obtained at Rf=0.39. The method was found to be linear, with r2=0.9961. The critical analytical attributes (CAAs) for the HPTLC method were identified. The saturation time, band length and solvent front were determined as critical method parameters (CMP) and extensively optimized employing Box-Behnken Design (BBD), with a focus on the retention factor (Rf) value as the CAA. The method described in this study exhibited linearity. The accuracy, precision, linearity, LOD, LOQ and robustness values were within the specified limits. The developed method was validated according to ICH guidelines and the results were found to be within the acceptance criteria. This study effectively demonstrates the value of the QbD approach for creating an incredibly accurate HPTLC method with improved system effectiveness.

description: The proposed nEXO experiment is searching for neutrinoless double beta decay (0νββ) in 136-Xe in a tonne-scale liquid xenon TPC. If observed, 0νββ will reveal the Majorana nature of neutrinos and violation of lepton number conservation. Searches for such extremely rare events require excellent background suppression and rejection methods to achieve high sensitivities. The identification or "tagging" of the xenon-136 ββ decay daughter barium-136 offers a very powerful discrimination technique and is being investigated as a potential upgrade for nEXO. By leveraging the 3D reconstruction of the TPC, a sample of xenon surrounding a candidate 0νββ can be extracted to tag the Ba daughter, if present. To this end, an apparatus is being developed to take a gaseous sample of xenon and transport a barium ion to high vacuum using an RF ion funnel. The ion is then trapped and identified via laser and mass spectroscopy.

New limit from the search for $0\nu\beta\beta$ of $^{100}$Mo with the CUPID-Mo experiment
Creators: name: Schmidt, Benjamin
Publisher: name: Zenodo
Year: 2020

description: The CUPID-Mo experiment, currently taking data at the Laboratoire Souterrain de Modane (France), is a demonstrator for a next-generation upgrade of the first ton-scale cryogenic $0\nu\beta\beta$-search, CUORE. The experiment is probing $0\nu\beta\beta$ of $^{100}$Mo with an array of 20 enriched 0.2 kg Li$_2$MoO$_4$ crystals and Ge light detectors allowing to distinguish $\alpha$ from $\beta/\gamma$ events by the detection of both heat and scintillation light signals. For the present analysis, we will employ the excellent bolometric performance of down to 5-6 keV energy resolution (FWHM) at 2615 keV, full $\alpha$-to-$\beta/\gamma$ separation and excellent radio-purity levels to perform a competitive search for $0\nu\beta\beta$ of $^{100}$Mo. With more than 2 kg$\cdot$yr of exposure an exclusion sensitivity comparable to the leading limit from NEMO-3 is expected.

description: This research delves into a systematic Analytical Quality by Design (AQbD) approach to develop and validate a stability-indicating robust RP-HPLC method for the simultaneous determination of Rutin and Curcumin, compounds known for their anti-inflammatory, antioxidant, and wound-healing properties. Utilizing QbD principles, critical method parameters (CMPs) were identified and screened using design of experiments (DoE) and optimized via response surface methodology (RSM) with Central Composite Design (CCD). The optimized chromatographic separation used a Phenomenex Luna C18 column with gradient elution, using methanol and 0.1% formic acid, a flow rate of 1 ml/min, and detection at 345 nm (isosbestic point). The retention times were 5.63 mins for Rutin and 17.01 mins for Curcumin. The stability indication of the developed HPLC method was performed, and validation parameters were meticulously conducted following the ICH Q2(R1) guidelines, demonstrating linearity over 2-10 μg/ml for Rutin and 5-25 μg/ml for Curcumin, with correlation coefficients of 0.9999 and 0.9998, respectively. Precision studies showed %RSD within acceptable limits, and accuracies ranged between 97-100%. This validated HPLC method offers a reliable, sensitive approach for simultaneous quantifying Rutin and Curcumin, suitable for routine analysis in pharmaceutical laboratories and quality control.

description: This article provides formal definitions characterizing well-formed composition of components in order to guarantee their safe deployment and execution. Our work focuses on the structural aspects of component composition; it puts together most of the concepts common to many component models, but never formalized as a whole. Our formalization characterizes correct component architectures made of functional and non-functional aspects, both structured as component assemblies. Interceptor chains can be used for a safe and controlled interaction between the two aspects. Our well-formed components guarantee a set of properties ensuring that the deployed component system has a correct architecture and can run safely. Finally, those definitions constitute the formal basis for our Eclipse-based environment for the development and specification of component-based applications.

The solutions are determined rather explicitly and the equilibrium orientation field is shown to vary between that of the Frank solution (possessing an axial disclination) and that of the disclination-free Cladis-Kleman solution as a scalar parameter in the free energy varies from 0 to [infinity]."
Sensitivity of SBN to eV mass-scale sterile neutrino oscillation
Creators: name: Larkin, Jacob
Publisher: name: Zenodo
Year: 2020

description: The Short Baseline Neutrino (SBN) program is a three-detector experiment, consisting of the SBND, MicroBooNE, and ICARUS detectors, which will search for oscillations of neutrinos from the Booster Neutrino Beam at Fermilab. SBN will be sensitive to $\nu_{\mu}$ disappearance and $\nu_e$ appearance, facilitating searches for eV mass-scale sterile neutrinos in the region of parameter space motivated by the LSND and MiniBooNE anomalies. The CAFAna fitting framework was developed in the context of the NOvA experiment and can be used to fit simulated SBN data with a "3+1" sterile neutrino model. We will demonstrate the sensitivity, including the impact of systematic uncertainty, of the three-detector SBN program to eV mass-scale sterile neutrino oscillation using the CAFAna fitting framework.

description: A series of chloroacetamide derivatives (1-22) was synthesized to address the urgent need for new antimicrobial and antioxidant agents. The chemical structures were confirmed by 1H-NMR, 13C-NMR and MS spectroscopic analyses. Most compounds inhibited in vitro Gram-positive bacteria S. aureus and B. cereus as well as Gram-negative bacteria (E. coli and P. aeruginosa) and yeast (C. albicans). Interestingly, compound 13 showed the broadest spectrum, especially against B. cereus (MIC = 10 mg/L). Compounds 6 and 20 displayed potent activity against C. albicans (EC50 = 197.02 and 189.13 mg/L, respectively). All compounds exhibited antioxidant activity, with 14 compounds surpassing α-tocopherol (standard) in DPPH radical scavenging. In silico analyses were conducted using molecular docking, drug-likeness data, physicochemical properties, and ADMET parameters to evaluate the potential of the compounds. Molecular docking simulations against the active sites of NADPH oxidase, penicillin-binding protein (bacterial target), and lanosterol 14-alpha demethylase (fungal target) revealed favorable binding energies for the majority of the compounds, indicating good affinity towards the targeted proteins. Overall, the research on novel multifunctional chloroacetamide derivatives is a valuable contribution to the field of biological chemistry and has the potential to lead to the development of new and improved products for a variety of microbes.
Prospects for Detecting the Highest Energy Tau Neutrinos with Elevated Beamforming Arrays
Creators: name: Southall, Dan
Publisher: name: Zenodo
Year: 2020

description: Identifying the flavor of astrophysical neutrinos will be a challenge for both current and proposed next-generation neutrino experiments that will have improved sensitivity to the diffuse astrophysical flux of ultra-high energy neutrinos. In order to probe predicted mixing ratios of neutrino flavors, an experiment capable of unambiguously measuring a single flavor of the neutrino flux is needed. The Beamforming Elevated Array for COsmic Neutrinos (BEACON) is a novel concept that searches for radio emission from up-going tau leptons produced by tau neutrino interactions in the Earth using a compact antenna array on a high elevation mountain. In this poster we present the upgraded BEACON prototype, located at the White Mountain Research Station in Bishop, CA. We discuss the current performance of the array, which has a goal of triggering on impulsive transients such as cosmic rays to determine the sensitivity of a future full-scale BEACON instrument.

description: After a brief overview about aesthetic and dramatic common motives in Salaviza’s work, we will focus on the hypothesis raised by the Cátia Diogo’s audiovisual essay Rafa and David (2022). The essay juxtaposes two scenes in Rafa (2012) and Montanha (2015), in which the condition of the “operative image” (Harun Farocki) is revealed. Taking into account a number of ideas that are expressed by the formal strategy that this audiovisual essay takes, we will speculate about how, in the intertextual relation between these films, is possible to envision a change of course in the work of João Salaviza, towards a cinema of impermanence.

Poisson Likelihood Covariance Technique for 3+1 Sterile Neutrino Searches in NOvA
Creators: name: Hewes, Jeremy
Publisher: name: Zenodo
Year: 2020

description: This poster presents a novel covariance matrix method for performing multi-detector fits, which combines a Gaussian multivariate treatment of systematic uncertainties with a Poisson likelihood treatment of statistical uncertainties. In this method, systematic uncertainties encoded into a covariance matrix are utilised to solve for the optimal systematic pulls in each analysis bin, and these systematically shifted bins are then used to calculate the statistical $\chi^{2}$ using a maximum likelihood technique with Poisson statistics. Unlike the standard Gaussian multivariate technique, this method provides an exact statistical treatment in the low statistics regime where the Gaussian approximation no longer applies. This method is discussed in the context of a two-detector search for 3+1 sterile oscillations in NOvA. Systematic uncertainties for this search are summarised, and sensitivities to 3+1 sterile oscillations utilising this technique are presented.

description: A new, user-friendly Ultra Performance Liquid Chromatography (UPLC) method was developed using Analytical Quality by Design (QbD) for precise analysis of Dacarbazine in both bulk powder and Dacarbazine-loaded Nanosponges. This method follows ICH guidelines and uses a statistically designed approach to optimize the separation conditions for Dacarbazine. A central composite design was implemented to identify the ideal combination of organic solvent (mobile phase composition) and flow rate. The UPLC method was successfully optimized for rapid separation (1.3 minutes) for Dacarbazine using a mobile phase consisting of 70% Methanol: 30% Orthophosphoric acid (0.1%) at a flow rate of 1.0 mL/min, using a Hypersil C18 column. The method exhibited excellent linearity with a correlation coefficient value of 0.997 across a concentration range of 4-20 μg/mL, accuracy (drug recovery of 96-100%) and sensitivity (LOD 1.15 μg/mL, LOQ 3.50 μg/mL) and it successfully quantified the drug in the formulated Dacarbazine-loaded Nanosponges. This QbD-driven UPLC method offers a valuable tool for reliable Dacarbazine quality control in pharmaceuticals providing rapid analysis, high accuracy, and low detection limits.

description: By the observation of geo-neutrinos originating from radioactive isotopes in the Earth (238U,232Th), we can know the amount of radioactive isotopes and the radiogenic heat which governs the Earth dynamics. Ocean Bottom Detector can observe geo-neutrinos from the mantle directly. Unlike existing other neutrino detectors, OBD detects neutrinos on the seafloor. Given that the oceanic crust is thinner than the continental crust and has lower densities of U and Th, ~70% of anti-neutrinos at OBD come from the mantle. Another unique feature of OBD is keeping the distance from the reactors which are the main background sources for continental detectors. In addition, this movable detector can observe at multiple points in the ocean. Currently we are considering the detector design. I estimated backgrounds from structures of detector and set upper limit of amount of isotopes. We will present results of detector design based on MC simulation.

description: Analytical quality by design and Response Surface Methodology based UPLC procedure has been developed for the concurrent quantification of four oral anti-diabetic drugs Metformin, Vildagliptin, Dapagliflozin and Sitagliptin in bulk and tablets. ANOVA was applied for responses statistical analysis. Retention times and peak resolutions were selected as critical quality attributes. The Critical method parameters (CMPs) considered for the Response surface methodology were the organic composition of the mobile phase (%), pH of the buffer, and flow rate. CMPs of the UPLC procedure were optimized employing a 16-runs 53 Central-composite design. The optimized procedure suggested by the desirability functions approach utilizing 49.3 volumes ethanol and 50.7 volumes pH 3.73, 0.1% Triethylamine buffer with 0.26 mL/min flow rate as mobile phase, Shield RP-18 (100 × 2.1 mm, 1.7 μm) column as a stationary phase with 4 min run time resulted in maximum desirability, 1.000. At 0.737 min, 1.425 min, 1.929 min and 2.645 min Metformin, Vildagliptin, Dapagliflozin and Sitagliptin retention times were observed respectively with acceptable resolution. The optimized procedure was validated and stress studies were executed following the ICHQ2(R1) and ICHQ1A, ICHQ1B guidelines respectively. The proposed technique was evaluated employing greenness assessment tool and 0.86 was the observed greenness score. In accordance with the literature, it is evident that this is the initially reported green UPLC procedure for Metformin, Vildagliptin, Dapagliflozin and Sitagliptin concurrent estimation.

description: By using two-fluid model the effect of impurities on the transition temperature of a dipolar trapped Bose gas is investigated. By treating Gaussian spatial correlation for impurities from the interaction modified spectra of the system, the formula for the shift of transition temperature is derived. The shift of the transition temperature contains essentially three contributions due to contact, dipole-dipole and impurity interactions. Applying our results to Dipolar Bose gases show that the shift of the transition temperature due to impurities could be measured for isotropic trap (dipole-dipole contributions is zero) and Feshbach resonance technique (contact potential contribution is negligible).

description: We present the results of large scale, three-dimensional magneto-hydrodynamics simulations of disc-winds for different initial magnetic field configurations. The jets are followed from the source to 90 AU scale, which covers several pixels of HST images of nearby protostellar jets. Our simulations show that jets are heated along their length by many shocks. We compute the emission lines that are produced, and find excellent agreement with observations. The jet width is found to be between 20 and 30 AU while the maximum velocities perpendicular to the jet is found to be up to above 100 km/s. The initially less open magnetic field configuration simulations results in a wider, two-component jet; a cylindrically shaped outer jet surrounding a narrow and much faster, inner jet. These simulations preserve the underlying Keplerian rotation profile of the inner jet to large distances from the source. However, for the initially most open magnetic field configuration the kink mode creates a narrow corkscrew-like jet without a clear Keplerian rotation profile and even regions where we observe rotation opposite to the disc (counter-rotating). The RW Aur jet is narrow, indicating that the disc field in that case is very open meaning the jet can contain a counter-rotating component that we suggests explains why observations of rotation in this jet has given confusing results. Thus magnetized disc winds from underlying Keplerian discs can develop rotation profiles far down the jet that are not Keplerian.

description: Signal sensor and readout cables are a fundamental component of rare event and ultrasensitive detectors. While possessing unique electrical and mechanical properties, flexible cables can be a significant contributor to the total detector background. Intrinsic contaminations of Th-232 and U-238 in commercially available flexible cables have been measured in the mBq/kg range, which can be significant compared to the levels required for next-generation rare event detectors. As a first step toward fabricating ultralow background cables, we investigated the possibility of obtaining low radioactivity (microBq/kg range) polyimides and copper-polyimide laminates for use in flexible cables. We have determined the dominant source of contamination in Kapton and demonstrated the ability to produce radiopure Kapton and Kapton-based laminates.

description: A newly developed ±550 kV DC GIL (direct current gas-insulated transmission line) prototype was erected at a HVDC test facility at the Technical University of Darmstadt to collect first service experience with this new equipment. The 100 m long DC GIL prototype is periodically stressed with DC voltage and DC current as well as superimposed impulse voltage. The test equipment was procured for the project and partly newly developed. The overall procedure follows the prototype installation test recommendations from CIGRE TB 842. This paper presents experience collected during the commissioning and long-term testing of the DC GIL prototype. The commissioning process, events occurred, as well as resulting conclusions for type, factory acceptance and site acceptance tests of DC GIL systems are discussed. The long-term operation of the DC GIL is intended to run continuously. Interruptions occur due to external influences only. Partial discharge events and the overall performance of the DC GIL prototype during long-term stress are presented.

Fascinating Museological Audiences, or the Cinematic Appeal
Creators: name: Chinita, Fátima
Publisher: name: Journal of Science and Technology of the Arts
Year: 2022

description: This review of Mandelli’s book The Museum as a Cinematic Space: The Display of Moving Images in Exhibitions (2019) explains how, according to Mandelli, several viewing dispositifs, understood as a rather flexible assemblage of elements, are increasingly being used in museums to combine education with entertainment. Thus, museums are becoming “cinematic spaces” with an ideological perspective. Mandelli’s approach to the projection technologies of moving images in museological venues is not only chronological but also phenomenological. A three-way interest is recognizable in the alignment of chapters, encompassing the educational value of the dispositifs, their artistic nature, and the experiential factor. As the book provides an interesting overview of two fields that usually are not taken together and contains an assortment of case studies described in detail, it should make a good addition to the fields of Museum and Film

description: We scrutinize the diagrammatic perturbation theory of noninteracting electrons in a random potential with the aim to accomplish a consistent comprehensive theory of quantum diffusion. Ward identity between the one-electron self-energy and the two-particle irreducible vertex is generally not guaranteed in the perturbation theory with only elastic scatterings. We show how the Ward identity can be established in practical approximations and how the functions from the perturbation expansion should be used to obtain a fully consistent conserving theory. We derive the low-energy asymptotics of the conserving full two-particle vertex from which we find an exact representation of the diffusion pole and of the static diffusion constant in terms of Green functions of the perturbation expansion. We illustrate the construction on the leading vertex corrections to the mean-field diffusion due to maximally-crossed diagrams responsible for weak localization.

description: Serious games are videogames that are used with purposes that go beyond the mere entertainment of the player. Among their many applications, healthcare is one of the most prominent ones, as serious games can have a wide range of uses within this field, namely physical rehabilitation of patients. For this purpose, both custom-made serious games and commercial entertainment titles, such as those for Nintendo Wii, can be used. However, while custom-made serious games appear to be more clinically effective, patients seem to prefer the gaming experience of playing a commercial title. This paper aims to compare the game goals and the aesthetics of Wii Sports (a commercial title used in the context of physical rehabilitation) with custom-made serious games that have obtained clinically significant results in upper limb rehabilitation, in order to try and understand what can be done to bridge the gap between these two approaches.

description: Molecular fragmentation leading to the formation of negatively and positively charged hydrogen ions in 7-keV OH$^+$ + Ar collisions is investigated experimentally. The most striking finding is that negative and positive hydrogen ions are emitted with very similar angular dependences. Also, the kinetic energy distribution of the H$^+$ fragment shows strong similarities with that of the ejected H$^-$ ion. The kinematics of the emitted H core is found to be essentially driven by its scattering on the atomic target. However, in addition to this binary-encounter process, dissociative electronic excitation of the molecular projectile has to be invoked to explain the observed fragmentation patterns. Though the electron capture process is complex, it is shown that the relative population of the different final charge states of the outgoing fragments can be described by simple statistical laws.

Muon Neutrino Disappearance in the Short Baseline Neutrino Program
Creators: name: Putnam, Gray
Publisher: name: Zenodo
Year: 2020

description: The accelerator neutrino experiments LSND and MiniBooNE both detected an excess of electron-like events at a short-baseline, anomalous with the standard three-neutrino oscillation picture. These results indicate the possibility of new eV-scale sterile neutrinos, but also may be an artifact of the poorly understood interactions between neutrinos and heavy nuclei. The Short-Baseline Neutrino (SBN) program at Fermilab will address this outstanding anomaly in neutrino physics through searches for muon neutrino disappearance and electron neutrino appearance in its muon neutrino beam. This analysis presents a preliminary muon neutrino charged current event selection in SBN based on detector simulation toward a future muon neutrino disappearance result. It demonstrates the ability of the SBN detectors to select a high purity of muon neutrino charged current interactions against the large background of cosmic muons at the earth's surface.
Time-Critical Animation: Comics, Cartoons, Computers

description: Digital animation was originally developed at scientific research laboratories, where it was seen as an ideal tool for scientific research due to its ability to visualize, analyze, and synthesize time-serial data. It was eventually adopted by the entertainment industry when higher image resolutions made it possible to produce photorealistic visual effects, yet it still has numerous applications in such fields as biology, meteorology, geology, engineering, mathematics, and physics. This paper will argue that the difference between analog and digital animation should be understood not in terms of the indexicality of the images but rather in terms of the temporalities of their material substrates – that is, the difference between the time-based medium of film and the time-critical medium of the computer. Such an approach not only offers an important contribution to the field of animation studies but also explains the continued importance of animation for contemporary scientific research.

description: We consider a string model at one-loop related to a $σ$-model whose antisymmetric tensor field is constructed as complex structure on the background manifold, specially on a manifold $R\times N$ where $N$ is a complex manifold. As an example, we consider a homogeneous anisotropic $(1+4)$-dimensional $σ$-model where space part of the background is a $4$-dimensional complex manifold. By solving the related one-loop $β$-functions we obtain a static solution so that by reduction of this solution to $(1+3)$-dimension we obtain a static solution of Einstein equation where the matter sector is effectively interpreted as an inhomogeneous, anisotropic and barotropic matter satisfying all the energy conditions. Finally, the $T$-dual background of the solution is investigated and it is shown that the duality transformation and reduction processes commute with each other.

description: Over the past year and a half, the Metadata Working Group has been working on changes to support the evolving use cases for DataCite DOIs. These proposed updates are in response to requests from DataCite community members and also in alignment with pillar 3 of DataCite’s strategic plan—that is, to “identify and connect all resource types held by research organizations globally.”
We want to make sure these changes work—that they solve the problems that they are intended to solve—and we want to hear from you! For the first time, we are sharing a draft proposal before releasing the next metadata schema version.
An off-centered active galactic nucleus in NGC 3115

description: NGC 3115 is an S0 galaxy that has always been considered to have a pure absorption-line spectrum. Some recent studies have detected a compact radio-emitting nucleus in this object, coinciding with the photometric center and with a candidate for the X-ray nucleus. This is evidence of the existence of a low-luminosity active galactic nucleus (AGN) in the galaxy, although no emission line has ever been observed. We report the detection of an emission-line spectrum of a type 1 AGN in NGC 3115, with an H$α$ luminosity of $L_{Hα} = (4.2 \pm 0.4) \times 10^{37}$ erg s$^{-1}$. Our analysis revealed that this AGN is located at a projected distance of $\sim 0.29" \pm 0.05"$ (corresponding to $\sim 14.3 \pm 2.5$ pc) from the stellar bulge center, which is coincident with the kinematic center of this object's stellar velocity map. The black hole corresponding to the observed off-centered AGN may form a binary system with a black hole located at the stellar bulge center. However, it is also possible that the displaced black hole is the merged remnant of the binary system coalescence, after the "kick" caused by the asymmetric emission of gravitational waves. We propose that certain features in the stellar velocity dispersion map are the result of perturbations caused by the off-centered AGN.

Geometrically exact beam formulation

description: This paper is concerned with the inverse dynamics of flexible mechanical systems whose motion is governed by quasi-linear hyperbolic partial differential equations. Problems that appear by applying classical solution strategies to the problem at hand, e.g. integrating the problem at hand sequentially in space and time will be adressed in this work. Motivated by the hyperbolic structure of the underlying initial boundary value problem, two methods that are based on a simultaneous space-time integration will be presented. Special emphasize will be given to the phenomena of wave propagation within geometrically exact beams and its relevance regarding the inverse dynamics problem.
Exploring New Physics at nuSTORM

Year: 2020

description: The Neutrinos from Stored muons (nuSTORM) facility has been proposed to measure $\nu_e ~ N$ and $\nu_\mu ~ N$ cross section very precisely. nuSTORM shows excellent promise to search for the existence of light sterile neutrinos that have been postulated to explain the LSND and MiniBooNE results with Charged Current events in a magnetized Iron calorimeter detector. In this study we study the effect of Neutral current events in conjunction with the CC events at the detector to probe the sterile neutrino parameters. We also explore the ability of nuSTORM to resolve the various non-unitarity parameters like $\alpha_{11}$, $|\alpha_{21}|$ and $\alpha_{22}$ considering both charged current and neutral current events.
