description: Antenna layout is an important design consideration for radio interferometers because it determines the quality of the snapshot point spread function (PSF, or array beam). This is particularly true for experiments targeting the 21 cm Epoch of Reionization signal as the quality of the foreground subtraction depends directly on the spatial dynamic range and thus the smoothness of the baseline distribution. Nearly all sites have constraints on where antennas can be placed---even at the remote Australian location of the MWA (Murchison Widefield Array) there are rock outcrops, flood zones, heritages areas, emergency runways and trees. These exclusion areas can introduce spatial structure into the baseline distribution that enhance the PSF sidelobes and reduce the angular dynamic range. In this paper we present a new method of constrained antenna placement that reduces the spatial structure in the baseline distribution. This method not only outperforms random placement algorithms that avoid exclusion zones, but surprisingly outperforms random placement algorithms without constraints to provide what we believe are the smoothest constrained baseline distributions developed to date. We use our new algorithm to determine antenna placements for the originally planned MWA, and present the antenna locations, baseline distribution, and snapshot PSF for this array choice.

description: From a medieval archaeological perspective, obvious sources for evidence of credit are limited or only indirectly available. This is even more true for the Early and High Middle Ages and the regions of Northern Europe, where even the written sources provide little evidence of pledged objects or means of payment. Nevertheless, a number of artefacts found mainly in (proto) urban trade centers can be linked to credit systems, or at least to over­arching currency areas and the social conceptions attached to them. Besides tally sticks, these are standardized ingots and a weight-related monetary system based on silver. These artefacts can thus be understood not only as part of an economic system, but also as part of a process of social interaction by which routine was established and trustworthiness communicated. Security was an essential requirement for credit transactions, as it was for trade. The paper thus discusses the mobile material sources on the medieval credit economy and the social practices associated with it. Keywords Credit; Medieval Archaeology; Material Cul­ture; Tally Sticks

Tetraiodothyroacetic Acid-Conjugated Polyethylenimine For Enhanced Delivery Of Plasmid Dna Via Integrin Receptor
Creators: name: Dehshahri, Ali
Publisher: name: Zenodo
Year: 2015

description: Targeted delivery of polymer-based nanoparticles has been considered as an efficient approach to transfer genetic materials such as plasmid DNA and siRNA. Given the presence of the binding site for tetraiodothyroacetic acid on integrin receptor and overexpression of integrin ?V?3receptor on tumor cells, early escape from endosomal compartment by the proton sponge effect of PEI and entry of tetraiodothyroacetic acid conjugated nanoparticles into cell nucleus by TR receptors, we hypothesized that conjugation of tetraiodothyroacetic acid with PEI may overcome three major barriers considered as the main obstacles in polycation-based gene delivery. In order to test the hypothesis, modified polymer/plasmid DNA complexes were prepared and their ability in transferring plasmid encoding Interleukin-12 was investigated. Moreover, the conjugates were characterized with respect to plasmid DNA condensation ability, particle size and zeta potential as well as cell-induced toxicity and plasmid protection against DNase degradation. The results demonstrated that tetraiodothyroacetic acid derivatives of PEI were able to condense plasmid encoding IL-12 gene at a carrier to plasmid DNA (C/P) weight ratio ? 2:1. The measured particle size was around 180 nm. The highest level of IL-12 gene expression was achieved by the nanoparticles prepared by modified PEI at carrier to plasmid ratio of 8 where they could increase the level of gene expression up to 4 times compared to that of naked plasmid. The cell viability in such C/P ratios is up to 85%. These results suggest that tetraiodothyroacetic acid conjugation of PEI is a simple modification strategy for future investigations aimed at developing a targeting gene vehicle.
Integrating Gene Synthesis & Microfluidic Protein Analysis For Rapid Protein Engineering

description: The ability to rapidly design proteins with novel functions will have a significant impact on medicine, biotechnology, and synthetic biology. While synthetic genes are becoming a commodity, integrated approaches that take full advantage of gene synthesis have yet to be produced. We developed a bench-top, solid-phase gene synthesis method based on asymmetric primer extension (APE) and demonstrated that linear templates from this technique can be used directly for high-throughput, on-chip protein expression, purification, and quantitative characterization using MITOMI (mechanically induced trapping of molecular interactions). Gene synthesis by APE is a restriction enzyme- and ligase-free method that operates without the need for transformation, sequencing, or PCR/oligomer purification steps. By coupling APE with cell-free protein expression and MITOMI (APE-MITOMI), we completely circumvent any molecular cloning and cell-based steps, reducing the time between gene design and protein characterization to 3-4 days per prototyping cycle. With APE-MITOMI we synthesized and characterized over 400 Cys2His2 zinc-finger (ZF) transcription factors (TF), showing that although ZF TFs can be readily engineered to recognize a particular target DNA sequence, rationally engineering the precise binding energy landscape remains difficult. We also show that it is possible to tune ZF - DNA affinity precisely and independently of sequence specificity. The APE gene synthesis method can be readily automated on standard liquid handling robots, making it possible to characterize hundreds to thousands of synthetic proteins per week. APE-MITOMI is a generic approach that should facilitate fundamental studies in protein biophysics and protein design/engineering, and by enabling a detailed exploration of the protein sequence-function relationship, improve the accuracy of computational models of protein function.
Observation of Reactor Electron Antineutrino Disappearance in the RENO Experiment

description: The RENO experiment has observed the disappearance of reactor electron antineutrinos, consistent with neutrino oscillations, with a significance of 4.9 standard deviations. Antineutrinos from six 2.8 GW$_{th}$ reactors at the Yonggwang Nuclear Power Plant in Korea, are detected by two identical detectors located at 294 m and 1383 m, respectively, from the reactor array center. In the 229 day data-taking period between 11 August 2011 and 26 March 2012, the far (near) detector observed 17102 (154088) electron antineutrino candidate events with a background fraction of 5.5% (2.7%). The ratio of observed to expected numbers of antineutrinos in the far detector is $0.920 \pm 0.009({\rm stat.}) \pm 0.014({\rm syst.})$. From this deficit, we determine $\sin^2 2 θ_{13} = 0.113 \pm 0.013({\rm stat.}) \pm 0.019({\rm syst.})$ based on a rate-only analysis.
description: The Chi^2 fit result on theta_13 is updated based on use of the constrained global normalization parameter within the the absolute reactor neutrino flux uncertainty of 2.5%. The systematic error is enhanced to lower the significance to 4.9 sigma. The updated Li/He background resulted in a new fit value of theta_13

Microscale Hydrogel Patterning To Manipulate Stem Cell Fate
Creators: name: Kolb, Laura
Publisher: name: Zenodo
Year: 2015

description: Stem cell behavior is strongly influenced by the physical and chemical cues originating from the extracellular matrix (ECM). In vivo, ECM signals are displayed in a spatiotemporally complex fashion. Current in vitro models to study the role of ECM signals in regulating stem cell behavior are rather limited in recapitulating this microenvironmental complexity, as they are mostly static and homogeneous. In order to achieve a dynamic control of the physical and biochemical properties of a hydrogel network, we here combined two crosslinking reaction schemes with photochemistry in order to control hydrogel stiffness in space, time and intensity.
First, thiol moieties of one of the reactive poly(ethylene glycol) (PEG) macromers undergoing crosslinking into a hydrogel network via Michael-type addition were equipped with caging groups. This prevented their reaction with vinyl sulfone groups on the termini of the complementary PEG macromers. Thus, the crosslinking density of the hydrogel network could be controlled by uncaging with light, directly translating into differential hydrogel stiffness. Using this approach, user-defined two-dimensional stiffness patterns between 3-8 kPa (E modulus) were obtained and shown to influence the directional migration of mesenchymal stem/progenitor cells in a Young's modulus-dependent manner with constant gradient strength. Cell migration was overall more directed on the photo-patterned substrate compared to the non-patterned region, with a bias towards the stiffer region above 5 kPa.
Second, we present an approach based on light-activated enzymatic crosslinking by which the biophysical properties of synthetic hydrogels can be modulated in 3D. A peptide substrate of the activated transglutaminase Factor XIII (FXIIIa), a key ECM crosslinking enzyme, was rendered photosensitive by masking its active site with a photolabile cage group. Covalent incorporation of this caged FXIIIa substrate together with the corresponding acceptor enzyme substrate into PEG hydrogels and subsequent laser-scanning lithography affords highly localized additional crosslinking. By encapsulation of intestinal stem cell-derived organoids followed by the photopatterning of precise three-dimensional stiffness areas we hope to be able to direct their self-organization.
These cytocompatible and versatile patterning concepts are highly promising for the manipulation of cell fate in stem cell research, disease modeling, and regenerative medicine.

description: This article examines tally sticks (tessera) as objects of contractual practice and accountability in credit relations between animal owners and herders in 15th-cen­tury Venetian Dalmatia. The statutory herding contract (societas animalium) between animal owners and herders marked the fundamental socio-economic form of organ­ising pastoral credit relations. On the island of Korčula, the lengthwise-split tally stick was a legal instrument for documenting and proving contract-based herding societies as acts of exchange and mutual compensation. Moreover, both in court and in social interaction, it served as a ma­terial symbol of the socio-economic symbiosis between herders and economic elites. Korčula’s extensive archival records facilitate a cultural, microhistorical perspective on pastoral contractual and accounting practices and the use of tally sticks as objects of pragmatic writing and instruments of accounting in the animal-related credit relations in late medieval Venetian Dalmatia.

description: Räumlich verteilte Systeme sind häufig komplex, so dass ein zentralisierter Ansatz keine effektive Regelung gewährleisten kann. Diese Arbeit behandelt diese Klasse von Systemen mit einem verteilten Ansatz, der die Dynamik auf räumlich diskreten Teilsystemen definiert. Jedes Teilsystem besitzt einen Aktuator und Sensor und kommuniziert mit seinen nächsten Nachbarn. Diskutiert werden Identifikation und Reglerentwurf sowohl für parameter-invariante als auch für parameter-variable Modelle. Die Anwendung wird für einen mit einer Reihe von Piezoelementen ausgestatteten Balken demonstriert. Es wird gezeigt, dass ein verteilter Ansatz zu einem effizienten, LMI-basierten Entwurf von verteilter Regelung und Anti-Windup führt.
description: Spatially-distributed systems are often large-scale systems, where a centralized scheme fails to realize an effective control. This thesis treats this class of systems in a distributed framework with dynamics defined on spatially-discretized subsystems, each equipped with actuating and sensing capabilities and interacting with nearest neighbours. Considered here are the identification and control of both parameter-invariant and parameter-varying models with application to a beam structure actuated and sensed by an array of collocated piezo patches. It shows that the distributed framework leads to efficient, LMI-based controller design and anti-windup compensator synthesis.

description: Constraints to the mass of a scalar field and the strength of its self-interacting coupling constant are obtained. This was done using observations of stellar dynamics at the center of our galaxy and by assuming that the dark compact object responsible of such dynamics is a boson star and not a supermassive black hole. We show that if such scalar field represents a spin-zero particle with cross section high enough to be considered collisional dark matter, there is a region of parameters compatible with both conditions: that the scalar field play the role of collisional dark matter and that it can form objects with the mass and compactness compatible with stellar kinematics.

description: CaCo$_{2}$As$_{2}$, a ThCr$_{2}$Si$_{2}$-structure compound, undergoes an antiferromagnetic transition at \emph{T$_{N}$}=76K with the magnetic moments being aligned parallel to the \emph{c} axis. Electronic transport measurement reveals that the coupling between conducting carriers and magnetic order in CaCo$_{2}$As$_{2}$ is much weaker comparing to the parent compounds of iron pnictide. Applying magnetic field along \emph{c} axis induces two successive spin-flop transitions in its magnetic state. The magnetization saturation behaviors with \emph{\textbf{H}$\parallel$c} and \emph{\textbf{H}$\parallel$ab} at 10K indicate that the antiferromagnetic coupling along \emph{c} direction is very weak. The interlayer antiferromagntic coupling constant \emph{J$_{c}$} is estimated to be about 2 meV.

description: Credit relationships represent specific forms of social interactions between money-lending actors. The actors involved are expected to trust each other both institutionally and personally, which also touches on the aspect of security. Objects – both mobile and immobile – are becoming the focus of interest as key components of security. Objects used to strengthen the relationship of trust refer to the social and cultural dimensions of credit transactions. Here, this aspect is be examined using the example of the municipal financial administration of the city of Vienna. Beyond the representative character of the objects, different categories of security practice seem to rein­force each other. Social status and creditworthiness are activated just as much as the possibilities of the objects’ usability. It will therefore be important to ask what role is attributed to these proxy or pawned objects on the basis of the cultural significance of their materials, their form or their contexts of origin, and what significance or function they had for specific credit practices in the social frame of reference and within the framework of the interaction of the actors involved.

description: This document represents version 3 of the ‘Requirements for certification of data centres’, published by ECRIN, the European Clinical Research Infrastructure Network (the first version was produced in 2011, and the second in 2012). The requirements are the criteria used by ECRIN to identify, and then certify, clinical trials units that can provide high quality, compliant and safe data management, as well as effective management of the underlying systems and IT infrastructure. This latest version results from a review in 2015 by ECRIN auditors, members of ECRIN’s data centre Certification Board, and invited experts from a variety of trials units in Europe, and it reflects experience gained auditing trials units in 2014.

Over and above their use for certification, the requirements are intended to describe good practice in data and IT management in clinical research, and in clinical trials in particular. They were developed by senior staff working in non-commercial clinical trials units in Europe, and are intended as a practical guide for staff working in IT and data management in that sector (though the same principles apply to all clinical research environments).

The 129 requirements, or standards, included in the current version are divided into 19 separate lists, some focused on IT, some mainly concerned with data management, and some that deal with both. Each standard has a code, a title, and a single statement summarizing the requirement. This document provides, in addition, explanatory and elaboration material – usually a few paragraphs that attempt to clarify each statement’s meaning, and / or give examples of its application, and which also indicate the evidence that would normally be used to assess a unit’s compliance. The document also includes a brief introduction to the standards and their development, including a description of the ECRIN audit process, and a glossary of terms.

description: We report the experimental observation of Landau quantization of molecular beam epitaxy grown Sb2Te3 thin films by a low-temperature scanning tunneling microscope. Different from all the reported systems, the Landau quantization in Sb2Te3 topological insulator is not sensitive to the intrinsic substitutional defects in the films. As a result, a nearly perfect linear energy dispersion of surface states as 2D massless Dirac fermion system is achieved. We demonstrate that 4 quintuple layers are the thickness limit for Sb2Te3 thin film being a 3D topological insulator. The mechanism of the Landau level broadening is discussed in terms of enhanced quasiparticle lifetime.

Year: 2022

description: One of the important sources for research into student credit relationships in the Middle Ages and Early Modern Times are letters by scholars. Only a small number of them from medieval times have survived. There is a bundle from two students from the time just after the turn of the 15th century, which concerns Bruno and Basilius Amerbach, who came from Basle and studied in Paris. Their correspondence is part of that of the well-known printer Johann Amerbach († 1513). It is possible to tell from these letters how Bruno and Basilius financed their studies in Paris, namely because they took out loans from specific persons there. This practice can be traced on the basis of the letters of the scholars. Here it concerned informal loans, the granting of which had been structured around the situation-related needs of the two young people. However, the substructure was based on the commercial contacts of their father and the networking structures derived from them. They arose from persons who were in the service of Johann Amerbach but also followed their own business activities, in the course of which they had to overcome the spatial distances between Basle and Paris. Hence the loans constituted a personal link between the two young people and their parents, and the letters were the tangible medium of both the family connection and the specific practice regarding loans.

description: We present a calculation of the leading order hadronic contribution to the anomalous magnetic moment of the muon for a dynamical simulation of 2+1 flavour QCD using domain wall fermions. The electromagnetic 2-point function is evaluated on the RBC-UKQCD lattice gauge configurations and this is fitted to a continuous form motivated by models of vector dominance. We determine a robust and reliable technique for performing this fit, allowing us to extract the most accurate results possible from our ensembles. This combined with data at very light quark masses produces the result a_μ^{(2)had}=641(33)(32) x 10^{-10} at the physical point, where the first uncertainty is statistical, and the second is an estimate of systematics, which is in agreement with previous results. We outline various methods by which this calculation can and will be improved in order to compete with the accuracy of alternative techniques of deducing this quantity from experimental scattering data.

Meeting The Challenge Of Genomics Data Storage And Security

description: Genome sequence data is the most sensitive medical record that human beings will create in their lifetime. The sequence data contains deep genotype-phenotype associations for the human condition, with some relationships not yet determined. Current research has elucidated many disease relationships, which are ushering in the rush for Precision medicine applications. However, the ability to read the genome for causal human traits infringes on privacy of individuals and their relatives. Because the data has implications on future generations, safe guarding an individual's genome data is essential to ensure that future generations will enjoy life without prejudice. Because an individual's sequence data encompasses large (100 Gigabytes to 1000 Gigabytes) digital files, several strategies have been put forward. However, current commercial strategies do not satisfy the concerns of groups for adequate security to safeguard the information for longterm (generational) storage. In this talk, I will discuss principles for secure long term storage (over generations) for genome sequence data.

description: We introduce a new family of quantum secret sharing protocols with limited quantum resources which extends the protocols proposed by Markham and Sanders and by Broadbent, Chouha, and Tapp. Parametrized by a graph G and a subset of its vertices A, the protocol consists in: (i) encoding the quantum secret into the corresponding graph state by acting on the qubits in A; (ii) use a classical encoding to ensure the existence of a threshold. These new protocols realize ((k,n)) quantum secret sharing i.e., any set of at least k players among n can reconstruct the quantum secret, whereas any set of less than k players has no information about the secret. In the particular case where the secret is encoded on all the qubits, we explore the values of k for which there exists a graph such that the corresponding protocol realizes a ((k,n)) secret sharing. We show that for any threshold k> n-n^{0.68} there exists a graph allowing a ((k,n)) protocol. On the other hand, we prove that for any k< 79n/156 there is no graph G allowing a ((k,n)) protocol. As a consequence there exists n_0 such that the protocols introduced by Markham and Sanders admit no threshold k when the secret is encoded on all the qubits and n>n_0.

description: [Abridged] We present a comparison between weak-lensing (WL) and X-ray mass estimates of a sample of numerically simulated clusters. The sample consists on the 20 most massive objects at redshift z=0.25 and Mvir > 5 x 10^{14} Msun h^{-1}. They were found in a cosmological simulation of volume 1 h^{-3} Gpc^3, evolved in the framework of a WMAP-7 normalized cosmology. Each cluster has been resimulated at higher resolution and with more complex gas physics. We processed it thought Skylens and X-MAS to generate optical and X-ray mock observations along three orthogonal projections. The optical simulations include lensing effects on background sources. Standard observational tools and methods of analysis are used to recover the mass profiles of each cluster projection from the mock catalogues. Given the size of our sample, we could also investigate the dependence of the results on cluster morphology, environment, temperature inhomogeneity, and mass. We confirm previous results showing that WL masses obtained from the fit of the cluster tangential shear profiles with NFW functionals are biased low by ~ 5-10% with a large scatter (~10-25%). We show that scatter could be reduced by optimally selecting clusters either having regular morphology or living in substructure-poor environment. The X-ray masses are biased low by a large amount (~25-35%), evidencing the presence of both non-thermal sources of pressure in the ICM and temperature inhomogeneity, but they show a significantly lower scatter than weak-lensing-derived masses. The X-ray mass bias grows from the inner to the outer regions of the clusters. We find that both biases are weakly correlated with the third-order power ratio, while a stronger correlation exists with the centroid shift. Finally, the X-ray bias is strongly connected with temperature inhomogeneities.

description: The eruption of the recurrent nova U Scorpii on 28 January 2010 is now the all-time best observed nova event. We report 36,776 magnitudes throughout its 67 day eruption, for an average of one measure every 2.6 minutes. This unique and unprecedented coverage is the first time that a nova has any substantial amount of fast photometry. With this, two new phenomena have been discovered: the fast flares in the early light curve seen from days 9-15 (which have no proposed explanation) and the optical dips seen out of eclipse from days 41-61 (likely caused by raised rims of the accretion disk occulting the bright inner regions of the disk as seen over specific orbital phases). The expanding shell and wind cleared enough from days 12-15 so that the inner binary system became visible, resulting in the sudden onset of eclipses and the turn-on of the supersoft X-ray source. On day 15, a strong asymmetry in the out-of-eclipse light points to the existence of the accretion stream. The normal optical flickering restarts on day 24.5. For days 15-26, eclipse mapping shows that the optical source is spherically symmetric with a radius of 4.1 R_sun. For days 26-41, the optical light is coming from a rim-bright disk of radius 3.4 R_sun. For days 41-67, the optical source is a center-bright disk of radius 2.2 R_sun. Throughout the eruption, the colors remain essentially constant. We present 12 eclipse times during eruption plus five just after the eruption.

Reaching The Holy Grail Of Biogeography - From Genome To Home Village
Creators: name: Elhaik, Eran
Publisher: name: Zenodo
Year: 2015

description: The search for a method that utilizes biological information to predict humans' place of origin has occupied scientists for millennia. Over the past four decades, scientists have employed genetic data to address this question with limited success. Biogeographical algorithms using next-generation sequencing data achieved an accuracy of 700 km in Europe but were inaccurate elsewhere. Here we develop the Geographic Population Structure (GPS) algorithm and demonstrate its accuracy with three datasets using 40,000-130,000 SNPs to improve this accuracy. GPS placed 83% of worldwide-individuals in their country of origin. Applied to over 200 Sardinians villagers, GPS places a quarter of them in their villages and most of the remaining within 50km of their villages. The accuracy and power of GPS to infer the biogeography of worldwide-individuals down to their country or, in some cases, village, of origin, underscore the promise of admixture-based methods for biogeography and has ramifications for genetic ancestry, population genetics, history, and health. Specific applications for the pharmaceutical industry will be discussed.

description: Observations of the clustering of galaxies can provide useful information about the distribution of dark matter in the Universe. In order to extract accurate cosmological parameters from galaxy surveys, it is important to understand how the distribution of galaxies is biased with respect to the matter distribution. The large-scale bias of galaxies can be quantified either by directly measuring the large-scale (λ >~ 60 hinv Mpc) power spectrum of galaxies or by modeling the halo occupation distribution of galaxies using their clustering on small scales (λ

description: In dieser Arbeit werden die ersten aktiven Dehnungs-Sensorikmessungen mit einen nanoporösen Metall-Hybridmaterial vorgestellt. Die hier hergeleitete thermodynamische Beziehung zwischen elastischen Eigenschaften, sowie Sensorik- und Aktorikparametern weist eine gute Übereinstimmung zwischen Experiment und Theorie auf. Diese Klasse von Materialien verhält sich phänomenologisch wie die der Piezokeramiken, obwohl die zugrundeliegenden Mechanismen völlig verschieden sind.
description: This thesis presents first experiments on active strain-sensing with a nanoporous-metal hybrid material. The thermodynamic relation between elastic properties, sensing- and actuation parameters that is derived in this work leads to good agreement between experiment and theory. The experiments show that this class of material behaves phenomenologically equally to piezoceramics although the underlying microscopic mechanisms are completely different.
The Extreme Microbiome Project

Publisher: name: Zenodo
Year: 2015

description: The Extreme Microbiome Project (XMP) is an international scientific effort to characterize the microbial composition of extremophilic and unique environments using whole genome shotgun sequencing of DNA and RNA along with classic culturing techniques. Sample collection sites including Lake Hillier in Western Australia, the ?Door to Hell? gas crater in Turkmenistan, deep ocean brine lakes, deep ocean sediments from Greenland, permafrost tunnels in the Arctic, and acidic saline lakes of Australia, as well as the fecal microbiomes of Penguin and Hummingbird. The goals of the XMP are multifaceted: to refine and standardize techniques for the detection and characterization of novel microbes, evaluate nucleic acid techniques for extremophilic samples, and to identify the appropriate bioinformatic pipelines needed for these types of samples. Specific initiatives include development of microbial reference standards for worldwide use, development of high performance DNA extraction reagents and enzymes specific for microbiome applications, as well as metagenomic specific collections devices. The XMP is a partnership which includes both academic and corporate scientists with the primary goal of advancing the science and tools of metagenomics.
Whole Genome Sequencing In Drug Discovery Research: A One Fits All Solution?
Creators: name: Sultan, Marc
Publisher: name: Zenodo
Year: 2015

description: With the recent availability of Illumina's HiSeq X ten sequencing platform, the cost of whole genome sequencing (WGS) has dropped to nearly $1,000 per genome. The affordability of WGS has now the potential of replacing other genotyping platforms such as whole exome sequencing (WES) and array based genotyping for (smaller) clinical study cohorts. In a recent pilot study, we compared the performance and genotyping quality of the HiSeq X WGS approach against WES and array based genotyping with respect to a number of applications and scientific questions using samples from clinical studies. In total we sequenced 115 individuals at 30x coverage; the sequencing data quality was very good and we observed high concordance of genotypes calls across the different platforms (>99%). In addition, WGS enables deeper analysis than the other platforms, including identification of novel SNPs and indels outside of coding regions. But the data management and the interpretation of the phenotypic effects of variants detected outside of exonic regions remain challenging. We expect to see rapid progress in these areas given the increasing availability WGS datasets.

description: We propose a sensitive and stable three-axis gyroscope in diamond. We achieve high sensitivity by exploiting the long coherence time of the N14 nuclear spin associated with the Nitrogen-Vacancy center in diamond, and the efficient polarization and measurement of its electronic spin. While the gyroscope is based on a simple Ramsey interferometry scheme, we use coherent control of the quantum sensor to improve its coherence time as well as its robustness against long-time drifts, thus achieving a very robust device with a resolution of 0.5mdeg/s/(Hz mm^3)^(1/2). In addition, we exploit the four axes of delocalization of the Nitrogen-Vacancy center to measure not only the rate of rotation, but also its direction, thus obtaining a compact three-axis gyroscope.
