description: We present a UV completion of the twin Higgs idea in the framework of holographic composite Higgs. The SM contribution to the Higgs potential is effectively cut off by the SM-singlet mirror partners at the sigma-model scale f, naturally allowing for m_{KK} beyond the LHC reach. The bulk symmetry is SU(7) X SO(8), broken on the IR brane into SU(7) X SO(7) and on the UV brane into (SU(3) X SU(2) X U(1))^{SM} X (SU(3) X SU(2) X U(1))^{mirror} X Z2. The field content on the UV brane is the SM, extended by a sector transforming under the mirror gauge group, with the Z2 exchanging the two sectors. An additional Z2 breaking term is holographically generated to reproduce the Higgs mass and VEV, with a mild O(10%) tuning. This model has no trace at the LHC, but can by probed by precision Higgs measurements at future lepton colliders, and by direct searches for KK excitations at a 100 TeV collider.

description: Mesothelioma is a form of cancer generally caused from previous exposure to asbestos. Although it was considered a rare neoplasm in the past, its incidence is increasing worldwide due to extensive use of asbestos. In the current practice of medicine, the gold standard for diagnosing mesothelioma is through a pleural biopsy with subsequent histologic examination of the tissue. The diagnostic tissue should demonstrate the invasion by the tumor and is obtained through thoracoscopy or open thoracotomy, both being highly invasive surgical operations. On the other hand, thoracocentesis, which is removal of effusion fluid from the pleural space, is a far less invasive procedure that can provide material for cytological examination. In this study, we aim at detecting and classifying malignant mesothelioma based on the nuclear chromatin distribution from digital images of mesothelial cells in effusion cytology specimens. Accordingly, a computerized method is developed to determine whether a set of nuclei belonging to a patient is benign or malignant. The quantification of chromatin distribution is performed by using the optimal transport-based linear embedding for segmented nuclei in combination with the modified Fisher discriminant analysis. Classification is then performed through a k-nearest neighborhood approach and a basic voting strategy. Our experiments on 34 different human cases result in 100% accurate predictions computed with blind cross validation. Experimental comparisons also show that the new method can significantly outperform standard numerical feature-type methods in terms of agreement with the clinical diagnosis gold standard. According to our results, we conclude that nuclear structure of mesothelial cells alone may contain enough information to separate malignant mesothelioma from benign mesothelial proliferations. © 2015 International Society for Advancement of Cytometry.

description: The pathology of the human abdominal aortic aneurysm (AAA) and its relationship to the later complication of intraluminal thrombus (ILT) formation remains unclear. The hemodynamics in the diseased abdominal aorta are hypothesized to be a key contributor to the formation and growth of ILT. The objective of this investigation is to establish a reliable 3D flow visualization method with corresponding validation tests with high confidence in order to provide insight into the basic hemodynamic features for a better understanding of hemodynamics in AAA pathology and seek potential treatment for AAA diseases. A stereoscopic particle image velocity (PIV) experiment was conducted using transparent patient-specific experimental AAA models (with and without ILT) at three axial planes. Results show that before ILT formation, a 3D vortex was generated in the AAA phantom. This geometry-related vortex was not observed after the formation of ILT, indicating its possible role in the subsequent appearance of ILT in this patient. It may indicate that a longer residence time of recirculated blood flow in the aortic lumen due to this vortex caused sufficient shear-induced platelet activation to develop ILT and maintain uniform flow conditions. Additionally, two computational fluid dynamics (CFD) modeling codes (Fluent and an in-house cardiovascular CFD code) were compared with the two-dimensional, three-component velocity stereoscopic PIV data. Results showed that correlation coefficients of the out-of-plane velocity data between PIV and both CFD methods are greater than 0.85, demonstrating good quantitative agreement. The stereoscopic PIV study can be utilized as test case templates for ongoing efforts in cardiovascular CFD solver development. Likewise, it is envisaged that the patient-specific data may provide a benchmark for further studying hemodynamics of actual AAA, ILT, and their convolution effects under physiological conditions for clinical applications.
Strategy of detection of solar CNO neutrinos with Borexino Phase-III data
Creators: name: Xuefeng Ding
Publisher: name: Zenodo
Year: 2020

description: The strategy to detect solar CNO neutrinos in Borexino is reported. Borexino is the only experiment that has measured the low-energy pp-chain solar neutrinos thanks to its exceptionally low radioactivity backgrounds. The CNO-cycle is a catalytic mechanism to fuse hydrogen into helium, and is important in most heavy stars. It has not been directed detected experimentally yet, but only as an inferred component of an integral neutrino measurement. This detection of solar CNO neutrinos would be its first direct experimental proof. In phase-III, after commissioning of a new temperature stabilization system, the detector convection current is significantly reduced which allows Borexino to track the content of Bi-210 decays through the decay of its daughter Po-210. Bi-210 has similar spectral shape of CNO neutrinos, and measurement of its rate paves the way to direct detection of CNO neutrinos.

description: This is now the third SJRCC editorial I have written during the COVID-19 pandemic. Since the last issue, several vaccines have received approval from regulatory authorities and the news on their efficacy is very good. The World Health Organization reports (18 February 2021) that seven vaccines are being deployed, and more than 200 vaccines are in development, more than 60 of which are at clinical research stages. Wealthier countries are farther along in vaccine roll-out, with Israel and the UK out in front. The real challenge is to ensure equitable distribution on a world scale. The WHO has developed the COVAX Facility as a mechanism for pooling vaccine procurement and distribution to middle and low-income countries.

description: We show that nanowire field-effect transistor (NWFET) arrays fabricated on both planar and flexible polymeric substrates can be reproducibly interfaced with spontaneously beating embryonic chicken hearts in both planar and bent conformations. Simultaneous recordings from glass microelectrode and NWFET devices show that NWFET conductance variations are synchronized with the beating heart. The conductance change associated with beating can be tuned substantially by device sensitivity, although the voltage-calibrated signals, 4-6 mV, are relatively constant and typically larger than signals recorded by microelectrode arrays. Multiplexed recording from NWFET arrays yielded signal propagation times across the myocardium with high spatial resolution. The transparent and flexible NWFET chips also enable simultaneous electrical recording and optical registration of devices to heart surfaces in three-dimensional conformations not possible with planar microdevices. The capability of simultaneous optical imaging and electrical recording also could be used to register devices to a specific region of the myocardium at the cellular level, and more generally, NWFET arrays fabricated on increasingly flexible plastic and/or biopolymer substrates have the potential to become unique tools for electrical recording from other tissue/organ samples or as powerful implants.

description: Pulmonary hypertension (PH) is a challenging disease process to manage. Respiratory and hemodynamic changes that accompany general anesthesia lead to a significant risk of cardiovascular collapse. Certain cases of decompensated PH require extracorporeal membrane oxygenation (ECMO) support as either a bridge to lung transplantation or bridge to recovery. Performing ECMO cannulation without intubation or general anesthesia in these patients may be safer given the severity of their underlying disease process. We present three cases of upper body ECMO cannulation performed on patients with pulmonary hypertension while awake and without mechanical ventilation.

description: We use a sample of 36 galaxies from the KINGFISH (Herschel IR), HERACLES (IRAM CO), and THINGS (VLA HI) surveys to study empirical relations between Herschel infrared (IR) luminosities and the total mass of the interstellar gas (H2+HI). Such a comparison provides a simple empirical relationship without introducing the uncertainty of dust model fitting. We find tight correlations, and provide fits to these relations, between Herschel luminosities and the total gas mass integrated over entire galaxies, with the tightest, almost linear, correlation found for the longest wavelength data (SPIRE500). However, we find that accounting for the gas-phase metallicity (affecting the dust-to-gas ratio) is crucial when applying these relations to low-mass, and presumably high-redshift, galaxies. The molecular (H2) gas mass is found to be better correlated with the peak of the IR emission (e.g. PACS160), driven mostly by the correlation of stellar mass and mean dust temperature. When examining these relations as a function of galactocentric radius we find the same correlations, albeit with a larger scatter, up to a radius of 0.7 r_25 (within which most of the galaxy's baryonic mass resides). However, beyond this radius the same correlations no longer hold, with the gas mass (predominantly HI) increasing relative to the infrared emission. The tight relations found for the bulk of the galaxy's baryonic content suggest that the total gas masses of disk-like (non-merging) galaxies can be inferred from far-infrared continuum measurements in situations where only the latter are available, e.g. in ALMA continuum observations of high-redshift galaxies.

description: In this study the magnetic order of the spin-1/2 XXZ chain system Cs$_2$CoCl$_4$ in a temperature range from 50 mK to 0.5 K and in applied magnetic fields up to 3.5 T is investigated by high-resolution measurements of the thermal expansion and the specific heat. Applying magnetic fields along a or c suppresses $T_\textrm{N}$ completely at about 2.1 T. In addition, we find an adjacent intermediate phase before the magnetization saturates close to 2.5 T. For magnetic fields applied along b, a surprisingly rich phase diagram arises. Two additional transitions are observed at critical fields $μ_0 H_{SF1}\simeq 0.25$ T and $μ_0 H_{SF2}\simeq 0.7$ T, which we propose to arise from a two-stage spin-flop transition.

title: The role of informal networks in the lives of young people transitioning from care : a review of the literature
Creators: name: Teer, Philip
Publisher: name: Strathprints - University of Strathclyde
Year: 2021

description: Young people leaving the care system face significant challenges when making the transition to adulthood, with limited support from other agencies. Their outcomes are significantly poorer than those of their non-care peers. This review aims to synthesise recent research on informal network support for care leavers making the transition to adulthood. Method: A systematic search was undertaken using three bibliographic databases: PsycINFO (Ovid platform), Social Care Online (SCIE) and Social Services Abstracts. Systematic searching identified three concepts: "children in care", "transition" and "social networks". Ten articles were identified for inclusion. Findings: Informal networks play an important role in promoting wellbeing and better outcomes in adulthood. There is also growing recognition of the importance of an educative approach to strengthen young people's internal resources, increase their ability to develop relationships and to raise awareness of the difficulties care leavers have in developing relationships due to trauma. Conclusion: Recent research highlights the emerging importance of interdependent living programmes to complement traditional independent living programmes and the important role relationships have for wellbeing and improving life outcomes for care leavers. The review identifies opportunities for further research to explore the development of interdependent approaches before the transition from care to adulthood.

description: We develop a functional framework suitable for the treatment of partial differential equations and variational problems on evolving families of Banach spaces. We propose a definition for the weak time derivative that does not rely on the availability of a Hilbertian structure and explore conditions under which spaces of weakly differentiable functions (with values in an evolving Banach space) relate to classical Sobolev-Bochner spaces. An Aubin-Lions compactness result is proved. We analyse concrete examples of function spaces over time-evolving spatial domains and hypersurfaces for which we explicitly provide the definition of the time derivative and verify isomorphism properties with the aforementioned Sobolev-Bochner spaces. We conclude with the proof of well posedness for a class of nonlinear monotone problems on an abstract evolving space (generalising the evolutionary p-Laplace equation on a moving domain or surface) and identify some additional problems that can be formulated with the setting developed in this work.

description: This chapter provides an overview of the heart and the biomimetic approaches used to engineer cardiac muscle tissue. It first describes the unique structure and function of cardiac muscle (myocardium), discusses how this dictates scaffold design, and then defines the benchmarks used to evaluate the performance of engineered cardiac tissue. Next, the chapter presents the different techniques researchers have developed to fabricate tissue-engineered cardiac scaffolds that mimic extracellular matrix (ECM) cues observed in the heart. For each case, the relevant physical, mechanical and/or chemical properties and the particular advantages and limitations of the approach, are discussed. Finally, the chapter discusses the persistent challenges to engineering functional cardiac tissue and the future directions of the field. Nano- and microfabrication techniques for cardiac tissue engineering enable the formation of scaffolds with anisotropic structure on the same scale as fibers in the native cardiac ECM.
Sterile Neutrino Search via Neutral-Current Disappearance with Antineutrinos in NOvA
Creators: name: Wallbank, Michael
Publisher: name: Zenodo
Year: 2020

description: Observations of neutrino oscillations from the majority of experiments are consistent with a three-flavor framework. However, the excess of events seen by LSND and MiniBooNE may be incompatible with this model and, to explain these data using neutrino mixing, require an additional, sterile, neutrino. These intriguing results are inconclusive and are in tension with findings from other short- and long-baseline experiments. The NOvA experiment, which uses two functionally-identical liquid scintillator detectors over an 810 km baseline in the Fermilab NuMI beam, has the potential to set world-leading limits on parameters governing sterile neutrino oscillations by searching for a deficit of neutral current interactions compared to that predicted at the two detectors. The results of this analysis when applied to the full NOvA 12.3e20 POT antineutrino dataset will be presented and the first limits on the mixing parameters from long-baseline antineutrinos, will be shown.

description: We are developing CaF$_2$ scintillating bolometers to search for for neutrinoless double beta decay of $^{48}$Ca. We realized large scintillating bolometers using 312g(50mm$\phi$ $\times$ 50mm cylinder) of undoped and Europium-doped CaF$_2$ crystals with a readout technology of metallic magnetic calorimeters. We used CaF$_2$ crystals with a large amount of internal $^{238}$U-series impurities to evaluate detector performance such as energy resolution and particle identification. We found that the thermal signal amplitudes are strongly position-dependent in both CaF$_2$ crystals. By analyzing the sequential alpha-decays (222Rn-218Po-214Pb), the energy resolution without position dependence was evaluated, and obtained to be 0.2% at 5MeV, in the case of undoped CaF$_2$ crystal. In the poster presentation, we will present the results obtained with this R&D measurements.

description: KamLAND-Zen experiment is a neutrino-less double-beta decay search experiment with $^{136}$Xe and the low background liquid scintillator (LS) detector. In order to suppress backgrounds proportional to volume, $^{136}$Xe loaded LS is stored in an inner balloon (IB) made of nylon. The IB was made as clean as possible. However, the contamination of $^{238}$U still remains, and its daughter nuclei $^{214}$Bi will be one of the largest backgrounds. Although $^{214}$Bi could be rejected by delayed coincidence tagging with $\alpha$-ray from $^{214}$Po, the tagging efficiency is not high enough due to the $\alpha$-ray absorption in nylon IB. To detect the $\alpha$-ray and tag $^{214}$Bi, we are planning to use a scintillation film for the IB in a future project, KamLAND2-Zen. In this presentation, we describe the performance of scintillation IB and its potential for a pulse shape discrimination.

description: We investigate and quantify the observed scatter in the empirical relationship between the broad line region size R and the luminosity of the active galactic nucleus (AGN), in order to better understand its origin. This study is motivated by the indispensable role of this relationship in the mass estimation of cosmologically distant black holes, but may also be relevant to the recently proposed application of this relationship for measuring cosmic distances. We study six nearby reverberation-mapped AGN for which simultaneous UV and optical monitoring data exist. We also examine the long-term optical luminosity variations of Seyfert 1 galaxy NGC 5548 and employ Monte Carlo simulations to study the effects of the intrinsic variability of individual objects on the scatter in the global relationship for a sample of ~40 AGN. We find the scatter in this relationship has a correctable dependence on color. For individual AGN, the size of the Hbeta emitting region has a steeper dependence on the nuclear optical luminosity than on the UV luminosity, that can introduce a scatter of ~0.08 dex into the global relationship, due the non-linear relationship between the variations in the ionizing continuum and those in the optical continuum. Also, our analysis highlights the importance of understanding and minimizing the scatter in the relationship traced by the intrinsic variability of individual AGN, since it propagates directly into the global relationship. We find that using the UV luminosity as a substitute for the ionizing luminosity can reduce a sizable fraction of the current observed scatter of ~0.13 dex.

description: Abstract: The interface between nanoscale electronic devices and biological systems enables interactions at length scales natural to biology, and thus should maximize communication between these two diverse yet complementary systems. Moreover, nanostructures and nanostructured substrates show enhanced coupling to artificial membranes, cells, and tissue. Such nano–bio interfaces offer better sensitivity and spatial resolution as compared to conventional planar structures. In this work, we will report the electrical properties of silicon nanowires (SiNWs) interfaced with embryonic chicken hearts and cultured cardiomyocytes. We developed a scheme that allowed us to manipulate the nanoelectronic to tissue/cell interfaces while monitoring their electrical activity. In addition, by utilizing the bottom-up approach, we extended our work to the subcellular regime, and interfaced cells with the smallest reported device ever and thus exceeded the spatial and temporal resolution limits of other electrical recording techniques. The exceptional synthetic control and flexible assembly of nanowires (NWs) provides powerful tools for fundamental studies and applications in life science, and opens up the potential of merging active transistors with cells such that the distinction between nonliving and living systems is blurred.

description: Ventricular assist devices (VADs) have significantly impacted the treatment of adult cardiac failure, but few options exist for pediatric patients. This has motivated our group to develop an implantable magnetically levitated rotodynamic VAD (PediaFlow®) for 3-20 kg patients. The second prototype design of the PediaFlow (PF2) is 56% smaller than earlier prototypes, and achieves 0.5-1.5 L/min blood flow rates. In vitro hemodynamic performance and hemolysis testing were performed with analog blood and whole ovine blood, respectively. In vivo evaluation was performed in an ovine model to evaluate hemocompatibility and end-organ function. The in vitro normalized index of hemolysis was 0.05-0.14 g/L over the specified operating range. In vivo performance was satisfactory for two of the three implanted animals. A mechanical defect caused early termination at 17 days of the first in vivo study, but two subsequent implants proceeded without complication and electively terminated at 30 and 70 days. Serum chemistries and plasma free hemoglobin were within normal limits. Gross necropsy revealed small, subclinical infarctions in the kidneys of the 30 and 70 day animals (confirmed by histopathology). The results of these experiments, particularly the biocompatibility demonstrated in vivo encourage further development of a miniature magnetically levitated VAD for the pediatric population. Ongoing work including further reduction of size will lead to a design freeze in preparation for of clinical trials.

Metallic magnetic calorimeters operated at low temperatures, in which the Ho-163 has been implanted, have been selected to conduct a high resolution, high statistics, and low background calorimetric measurement of the Ho-163 EC spectrum. In order to reliably infer the energy of Ho-163 events and discard triggered noise or pile-up events, fast and robust analysis algorithms are required. We present the results obtained by applying the analysis algorithms to different data files affected in a different manner by noise sources. Based on these results, we then discuss the present structure for data reduction algorithms to be applied for the analysis of the ECHo-1k high statistics data.

description: An ideal quantum walk transitions from one vertex to another with perfect fidelity, but in physical systems, the particle may be hindered by potential energy barriers. Then the particle has some amplitude of tunneling through the barriers, and some amplitude of staying put. We investigate the algorithmic consequence of such barriers for the quantum walk formulation of Grover's algorithm. We prove that the failure amplitude must scale as $O(1/\sqrt{N})$ for search to retain its quantum $O(\sqrt{N})$ runtime; otherwise, it searches in classical $O(N)$ time. Thus searching larger "databases" requires increasingly reliable hop operations or error correction. This condition holds for both discrete- and continuous-time quantum walks.

description: We determine the regime where the widespread classical field description for quantum Bose gases is quantitatively accurate in 1d, 2d, and 3d by a careful study of the ideal gas limit. Numerical benchmarking in 1d shows that the ideal gas results carry over unchanged into the weakly interacting gas. The optimum high energy cutoff is in general shown to depend strongly on the observable in question (e.g. energy, density fluctuations, phase coherence length, condensate fraction). This explains the wide spread of past results. A consistent classical field representation with less than 10% deviation in all typical observables can be given for systems at temperatures below 0.0064 degeneracy temperature in 1d, and 0.49 critical temperature in 3d. Surprisingly, this is not possible for the 2d ideal gas even at zero temperature because mean density, density fluctuations and energy cannot be simultaneously matched to the quantum results.

description: Image-based morphometry is an important area of pattern recognition research, with numerous applications in science and technology (including biology and medicine). Fisher Linear Discriminant Analysis (FLDA) techniques are often employed to elucidate and visualize important information that discriminates between two or more populations. We demonstrate that the direct application of FLDA can lead to undesirable errors in characterizing such information and that the reason for such errors is not necessarily the ill conditioning in the resulting generalized eigenvalue problem, as usually assumed. We show that the regularized eigenvalue decomposition often used is related to solving a modified FLDA criterion that includes a least-squares-type representation penalty, and derive the relationship explicitly. We demonstrate the concepts by applying this modified technique to several problems in image-based morphometry, and build discriminant representative models for different data sets.

description: Right ventricular failure is a significant complication following implantation of a left ventricular assist device (LVAD), which increases morbidity and mortality. Consequently, researchers have sought predictors that may identify patients at risk. However, they have lacked sensitivity and/or specificity. This study investigated the use of a decision tree technology to explore the preoperative data space for combinatorial relationships that may be more accurate and precise. We retrospectively analyzed the records of 183 patients with initial LVAD implantation at the Artificial Heart Program, University of Pittsburgh Medical Center, between May 1996 and October 2009. Among those patients, 27 later required a right ventricular assist device (RVAD+) and 156 remained on LVAD (RVAD-) until the time of transplantation or death. A synthetic minority oversampling technique (SMOTE) was applied to the RVAD+ group to compensate for the disparity of sample size. Twenty-one resampling levels were evaluated, with decision tree model built for each. Among these models, the top six predictors of the need for an RVAD were transpulmonary gradient (TPG), age, international normalized ratio (INR), heart rate (HR), aspartate aminotransferase (AST), prothrombin time, and right ventricular systolic pressure. TPG was identified to be the most predictive variable in 15 out of 21 models, and constituted the first splitting node with 7 mmHg as the breakpoint. Oversampling was shown to improve the senstivity of the models monotonically, although asymptotically, while the specificity was diminished to a lesser degree. The model built upon 5X synthetic RVAD+ oversampling was found to provide the best compromise between sensitivity and specificity, included TPG (layer 1), age (layer 2), right atrial pressure (layer 3), HR (layer 4,7), INR (layer 4, 9), alanine aminotransferase (layer 5), white blood cell count (layer 5,6, &7), the number of inotrope agents (layer 6), creatinine (layer 8), AST (layer 9, 10), and cardiac output (layer 9). It exhibited 85% sensitivity, 83% specificity, and 0.87 area under the receiver operating characteristic curve (RoC), which was found to be greatly improved compared to previously published studies.
Searching for high-energy neutrinos from core-collapse supernovae
Creators: name: Necker, Jannis
Publisher: name: Zenodo
Year: 2020

description: The IceCube Detector is a cubic kilometre neutrino detector array in the antarctic ice, looking for astrophysical, high-energy neutrinos. The collected data reveal a diffuse flux of these neutrinos over the whole sky, indicating an extragalactic origin. A possible contribution to this diffuse flux could stem from core-collapse supernovae. The neutrinos could either come from the interaction of the ejecta with a dense circumstellar medium or a jet, emanating from the star's core, that stalls in the star's envelope. In this poster I will present results of a Stacking Analysis to search for this high-energy neutrino emission from core-collapse supernovae.
Modular Symmetry Approach to Neutrino Masses and Mixing

description: We investigate minimal phenomenologically viable models of charged lepton and neutrino masses and lepton mixing based on non-linearly realized modular symmetry. While successfully accommodating charged lepton masses, neutrino mass-squared differences and mixing angles, these models predict the values of the lightest neutrino mass (i.e., the absolute neutrino mass scale), the Dirac and Majorana CP violation phases, as well as specific correlations between the observables.

Content advisories

description: Lightning Talk for iPres 2024

There is an increasing importance to ensure that archive users have informed consent regarding what they are viewing. When this is applied to a digital archive, it can be more difficult to ensure that users know what they are accessing prior to viewing it due to the number of ways that digital data can be accessed. Add in the further complication of human remains from a British early medieval cemetery and things get a bit more complicated. The Archaeology Data Service, as a part of the High Speed 2 (HS2) infrastructure project, was tasked with archiving and disseminating data pertaining to the human remains from several cemeteries that were excavated over the course of the project. This talk will discuss the steps that the ADS took to add content advisories and context to digital archives that contained digital objects relating to different individuals.

So how was this done? Each digital archive and digital object that contains data about human remains receives a tag stating what sensitive information it contains. This tag then triggers notifications on the archive metadata page, the object metadata page, and blurs images/3D models where applicable. While this approach works to provide practical information for users, we felt that some digital objects should also be disseminated with additional contextual information. Within the medieval cemeteries excavated as part of HS2, most individuals were not easily identifiable, but we could give as much context as possible to each individual by linking each individual’s photogrammetry model with associated contextual information and excavation photos. This information was provided on an individual level with a specific web page that displayed an interactive 3D model and the associated contextual information. For larger cemeteries, the individuals were also presented spatially by showing their burial locations on a web map with a sidebar that provides the additional contextual information and links to the individual’s information page. The tagging and techniques that were used can be applied more broadly and include instances where harmful language is used for example and we hope to apply what we learned from HS2 to the rest of our archival holdings.

description: In quantum information theory, the reliable and effective detection of entanglement is of paramount importance. However, given an unknown state, assessing its entanglement is a challenging task. To attack this problem, we investigate the use of random local measurements, from which entanglement witnesses are then constructed via semidefinite programming methods. We propose a scheme of successively increasing the number of measurements until the presence of entanglement can be unambiguously concluded, and investigate its performance in various examples.
