description: Motivated by the standard form of string-theory amplitude, we calculate the field-theory amplitude to complete the higher-derivative terms in type II supergravity theories in their conventional form. We derive explicitly the $ O(α'^3) $ interactions for the RR (Ramond-Ramond) fields with graviton, B-field and dilaton in the low-energy effective action of type II superstrings. We check our results by comparison with previous works that have been done by the other methods, and find an exact agreement.

description: Feshbach resonances, which allow for tuning the interactions of ultracold atoms with an external magnetic field, have been widely used to control the properties of quantum gases. We propose a~scheme for using scattering resonances as a probe for external fields, showing that by carefully tuning the parameters it is possible to reach a $10^{-5}$G (or nT) level of precision with a single pair of atoms. We show that for our collisional setup it is possible to saturate the quantum precision bound with a simple measurement protocol.

description: There is an ongoing search for a physical or operational definition for quantum mechanics. Several informational principles have been proposed which are satisfied by a theory less restrictive than quantum mechanics. Here, we introduce the principle of "many-box locality", which is a refined version of the previously proposed "macroscopic locality". These principles are based on coarse-graining the statistics of several copies of a given box. The set of behaviors satisfying many-box locality for $N$ boxes is denoted $MBL_N$. We study these sets in the bipartite scenario with two binary measurements, in relation with the sets $\mathcal{Q}$ and $\mathcal{Q}_{1+AB}$ of quantum and "almost quantum" correlations. We find that the $MBL_N$ sets are in general not convex. For unbiased marginals, by working in the Fourier space we can prove analytically that $MBL_{N}\subsetneq\mathcal{Q}$ for any finite $N$, while $MBL_{\infty}=\mathcal{Q}$. Then, with suitably developed numerical tools, we find an example of a point that belongs to $MBL_{16}$ but not to $\mathcal{Q}_{1+AB}$. Among the problems that remain open, is whether $\mathcal{Q}\subset MBL_{\infty}$.

description: Lung adenocarcinoma (LUAD) is a deadly cancer with a high incidence worldwide. Long noncoding RNAs (lncRNAs) have been confirmed to have the regulatory effects on the occurrence and development of LUAD. But the specific functions of lncRNA GLIDR in LUAD are still not explicit and need to be investigated. On the basis of the outcomes of RT-qPCR experiments, the relative expression of GLIDR was evidently up-regulated in LUAD cells, while that of miR-1270 was down-regulated. The down-regulation of GLIDR inhibits cell proliferation in accordance with the results of CCK-8, EdU and colony formation assays, and accelerates cell apoptosis according to the results of flow cytometry and JC-1 analyses. Luciferase reporter, RNA pull down and RIP assays indicated that GLIDR could sponge miR-1270 in LUAD. Additionally, TCF12 was proved as the target gene of miR-1270. Furthermore, rescue experiments indicated that overexpression of TCF12 could offset the inhibitory functions of silencing GLIDR on cell behaviors. In brief, this study has demonstrated that GLIDR/miR-1270/TCF12 axis plays the crucial role in LUAD, which offers a new insight into researches on molecular mechanism concerning LUAD and provides with a new perspective for LUAD treatment.

description: Ants commonly participate simultaneously in mutualisms with honeydew-producing hemipterans and extrafloral nectar-bearing host plants. These interactions are based on the exchange of resources (honeydew and extrafloral nectar) for ant protection against natural enemies. The benefits may vary according to the species of ant interacting, and the outcomes for the host plant and hemipteran will depend on the results of the ant-plant-hemipteran relationship as a whole. We studied a plant-mealybug association with Camponotus crassus Mayr (Formicinae) and Ectatomma tuberculatum Olivier (Ectatomminae) in a Brazilian tropical savanna. We aimed to elucidate whether the frequency of visitation by different species of ants can be affected by neighbouring colonies of mealybugs, and whether these ant species influence the number of hemipterans in a different way. Furthermore, we intended to find out whether the interaction between ant and hemipteran has any effect on the proportion of fruit production or on the abundance of trophobiont and non-trophobiont herbivores, also influenced by the ant species. Our results show that neighbouring aggregations of mealybugs influenced the frequency of ant visitation and the ants affected the number of nymphs over time, with both positive results only for C. crassus. We also detected an indirect negative effect on proportion of fruit production and an increase in abundance of trophobiont and non-trophobiont herbivores in the presence of C. crassus-mealybug interaction. Thus, we provide further evidence that colonies of hemipterans interacting with ants can be beneficial for these herbivorous insects, but they are quite harmful to the host plant. Nevertheless, the outcomes can be highly conditional in relation to ant species.

description: Homogeneous nucleation from aluminum (Al) melt was investigated by million-atom molecular dynamics (MD) simulations utilizing the second nearest neighbor modified embedded atom method (MEAM) potentials. The natural spontaneous homogenous nucleation from the Al melt was produced without any influence of pressure, free surface effects and impurities. Initially isothermal crystal nucleation from undercooled melt was studied at different constant temperatures, and later superheated Al melt was quenched with different cooling rates. The crystal structure of nuclei, critical nucleus size, critical temperature for homogenous nucleation, induction time, and nucleation rate were determined. The quenching simulations clearly revealed three temperature regimes: sub-critical nucleation, super-critical nucleation, and solid-state grain growth regimes. The main crystalline phase was identified as face-centered cubic (fcc), but a hexagonal close-packed (hcp) and an amorphous solid phase were also detected. The hcp phase was created due to the formation of stacking faults during solidification of Al melt. By slowing down the cooling rate, the volume fraction of hcp and amorphous phases decreased. After the box was completely solid, grain growth was simulated and the grain growth exponent was determined for different annealing temperatures.

description: Competence in the management and disclosure of medical error (DME) is vital for medical graduates. Despite its importance, doctors frequently report challenges with DME in practice; key reasons for which include late and/or inadequate training. The aim of this study was to design and evaluate a virtual patient (VP) that supports early training in DME and empathic communication, using recently published recommendations by Lee et al. (2020) as a conceptual framework, and Cognitive Load Theory (CLT) to provide a theoretical lens. VP design comprised a multi-disciplinary approach and included script/scenario and technical development, resulting in a branching design consultation with integrated instructional interventions. VP evaluation in terms of system usability and learning effectiveness was performed using a mixed methods approach with two key study phases involving 27 third-year medical students, and procedures included: the Think Aloud method and post-activity interviews (with subsequent thematic analysis), as well as a quantitative post-activity Cognitive Load Questionnaire (CLQ). Qualitative findings indicated that the VP was technically sound, realistic, and useful from a learning perspective, and this was supported by CLQ results. Key design features that supported learning included: realism (which appeared to promote patient-centred communication), and the three-response option branching design (which supported novice learners). This study highlights that carefully designed VPs can be used to support early training in DME and empathic communication skills, and the CLT allows for in-depth understanding in how this can be achieved. While such a learning tool will never negate the need for in-person training, it allows for remote learning and offers novices time to practice and build cognitive schemas, so that they can make the most of limited higher fidelity training at a later stage. Further research is needed to rigorously evaluate such a VP in terms of skills acquisition and its effects on long-term learning outcomes.

description: We consider testing the ability of quantum network nodes to execute multi-round quantum protocols. Specifically, we examine protocols in which the nodes are capable of performing quantum gates, storing qubits and exchanging said qubits over the network a certain number of times. We propose a simple ping-pong test, which provides a certificate for the capability of the nodes to run certain multi-round protocols. We first show that in the noise-free regime the only way the nodes can pass the test is if they do indeed possess the desired capabilities. We then proceed to consider the case where operations are noisy, and provide an initial analysis showing how our test can be used to estimate parameters that allow us to draw conclusions about the actual performance of such protocols on the tested nodes. Finally, we investigate the tightness of this analysis using example cases in a numerical simulation.

description: We discuss the entropy carried by a quark-antiquark pair, in particular across the deconfinement transition. We therefore rely on a self-consistent solution to Einstein-Maxwell-dilaton gravity, capable of mimicking essential features of QCD. In particular we introduce a novel model that still captures well the QCD confinement and deconfinement phases, while allowing the introduction of a temperature in a phase which resembles the confined phase, this thanks to it being dual to a small black hole. We pay due attention to some subtleties of such model. We confirm the lattice picture of a strong build-up of thermal entropy towards the critical temperature T_c, both coming from below or above T_c. We also include a chemical potential, confirming this entropic picture and we consider its effect on the speed of sound. Moreover, the temperature dependent confinement phase from the holography side allows us to find a string tension that does not vanish at T_c, a finding also supported by lattice QCD.

Suggested Practices for Recording the CARE Principles for Place-based Research Samples and Data: for the Future and for the Past

description: Indigenous Data Sovereignty is the right of Indigenous Peoples to govern the collection, ownership, and application of data about Indigenous communities, peoples, lands, and resources (AIATSIS, 2019). This sovereignty extends beyond cultural heritage objects, to include Earth and environmental samples and data collected for place-based research. Historically, the initial collection of samples did not always include standard ways to document if consent was received from the local Indigenous communities or other Indigenous interests in the sample metadata, including permissions for reuse. Further, even if such metadata existed, there is little guarantee that these properties will be carried through to downstream subsamples and any derived analytical data. Without persistent connections of such metadata, including Local Context Notices and Labels, it is difficult to determine provenance, or that the primary samples were collected ethically.

The CARE Principles for Indigenous Data Governance (Carroll et al. 2020) provide a high-level framework for the governance and management of Indigenous data. However, they do not specify how and where these principles should be expressed in a standardised, machine-actionable way for physical research samples, subsamples, data and data products.

This paper will highlight how CARE can be operationalised before collection and retroactively. An example from the University of California Berkeley Gump South Pacific Research Station, will describe how a field station is incorporating a cultural review process and Local Contexts Notices and Labels before granting research access. For the past, this paper considers retrospectively applying CARE metadata and Local Context Notices and Labels to legacy sample collections.

description: Multicore processors serve as target platforms in a broad variety of applications ranging from high-performance computing to embedded mobile computing and automotive applications. But, the required parallel programming opens up a huge design space of parallelization strategies each with potential bottlenecks. Therefore, an early estimation of an application’s performance is a desirable development tool. However, out-of-order execution, superscalar instruction pipelines, as well as communication costs and (shared-) cache effects essentially influence the performance of parallel programs. While offering low modeling effort and good simulation speed, current approximate analytic models provide moderate prediction results so far. Virtual prototyping requires a time-consuming simulation, but produces better accuracy. Furthermore, even existing statistical methods often require detailed knowledge of the hardware for characterization. In this work, we present a concept called Multicore Performance Evaluation Tool (MPET) and its evaluation for a statistical approach for performance prediction based on abstract runtime parameters, which describe an application’s scalability behavior and can be extracted from profiles without user input. These scalability parameters not only include information on the interference of software demands and hardware capabilities, but indicate bottlenecks as well. Depending on the database setup, we achieve a competitive accuracy of 20% mean prediction error (11% median), which we also demonstrate in a case study.

We explore the pressure dependent elastic, mechanical and thermodynamic properties of this newly discovered Na2He by using ab initio technique. The calculation presents good accordance between the theoretical and experimental lattice parameters. Though the most stable structure of Na2He is found at 300 GPa, present study ensures the mechanical stability of this compound up to 500 GPa. However, the Debye temperature, melting temperature and minimum thermal conductivity of Na2He are also calculated and discussed at different pressure.

Timelike duality, $M'$-theory and an exotic form of the Englert solution

Year: 2017
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Through timelike dualities, one can generate exotic versions of $M$-theory with different spacetime signatures. These are the $M^*$-theory with signature $(9,2,-)$, the $M'$-theory, with signature $(6,5,+)$ and the theories with reversed signatures $(1,10, -)$, $(2,9, +)$ and $(5,6, -)$. In $(s,t, \pm)$, $s$ is the number of space directions, $t$ the number of time directions, and $\pm$ refers to the sign of the kinetic term of the $3$ form. The only irreducible pseudo-riemannian manifolds admitting absolute parallelism are, besides Lie groups, the seven-sphere $S^7 \equiv SO(8)/SO(7)$ and its pseudo-riemannian version $S^{3,4} \equiv SO(4,4)/SO(3,4)$. [There is also the complexification $SO(8,\mathbb{C})/SO(7, \mathbb{C})$, but it is of dimension too high for our considerations.] The seven-sphere $S^7\equiv S^{7,0}$ has been found to play an important role in $11$-dimensional supergravity, both through the Freund-Rubin solution and the Englert solution that uses its remarkable parallelizability to turn on non trivial internal fluxes. The spacetime manifold is in both cases $AdS_4 \times S^7$. We show that $S^{3,4}$ enjoys a similar role in $M'$-theory and construct the exotic form $AdS_4 \times S^{3,4}$ of the Englert solution, with non zero internal fluxes turned on. There is no analogous solution in $M^*$-theory.

description: Background: This comparison of PRAsugrel and clopidogrel in Japanese patients with ischemic STROke (PRASTRO)-I trial investigates the noninferiority of prasugrel to clopidogrel sulfate in the prevention of recurrence of primary events (ischemic stroke, myocardial infarction, and death from other vascular causes), and the long-term safety of prasugrel in Japanese patients with non-cardioembolic stroke. Research design and methods: This was an active-controlled, randomized, double-blind, double-dummy, parallel-group study conducted between July 2011 and March 2016 at multiple centers around Japan. Patients had to meet eligibility criteria before receiving 3.75 mg prasugrel or 75 mg clopidogrel orally once daily for a period of 96–104 weeks. Results: A total of 3747 patients were included in this trial; 1598 in the 3.75 mg prasugrel group and 1551 in the 75 mg clopidogrel group completed the study. During the study period, 287 (15.2%) patients in the prasugrel group and 311 (16.7%) in the clopidogrel group discontinued treatment. Baseline characteristics, safety, and efficacy results are forthcoming and will be published separately. Conclusions: This article presents the study design and rationale for a trial investigating the noninferiority of prasugrel to clopidogrel sulfate with regards to the inhibitory effect on primary events in patients with non-cardioembolic stroke.

description: Obesity and the metabolic complications associated with it are increasing globally. Sedentary lifestyles, poor diet and genetic predisposition contribute to obesity. In addition, environmental chemicals such as Bisphenol A (BPA) may play a significant role. Exposure to BPA has been correlated with an array of adverse health effects on the endocrine system and whole-body homeostasis. This has resulted in manufacturers replacing it with structural analogues such as Tetra Methyl Bisphenol F (TMBPF), Bisphenol F (BPF), Bisphenol AP (BPAP), and fluorine-9-bisphenol (BHPF). BPA is a suspected obesogen as it can induce adipogenesis in human and murine preadipocytes. The effects of the BPA analogues listed above on adipogenesis have yet to be evaluated. The aim of this project is to investigate their adipogenic effects. For this purpose, we used 3T3-L1 mouse embryonic fibroblasts. This cell model can be differentiated into mature adipocytes with appropriate inducers including 3-isobutyl-1-methylxanthine (IBMX), insulin and dexamethasone, a synthetic steroid. To assess the effects of BPA analogues, the cells were treated with varying concentrations of TMBPF, BPF, BHPF, BPA, or BPAP in place of dexamethasone. The expression levels of mature adipocyte markers were assessed at mRNA and protein levels to determine the adipogenic potential of the analogues. Lipid accumulation was evaluated by Nile Red staining. A time course was performed to assess the expression levels of known transcriptional regulators of adipogenesis. The results indicate that TMBPF, BPF and BPA increase 3T3-L1 adipogenesis. BHPF and BPAP did not affect adipogenesis in this model. BPF appears to be at least as good as BPA at inducing adipogenesis. TMBPF, on the other hand, can induce adipogenesis to a greater extent than the other chemicals, including BPA, as evidenced by increased expression of adipogenic markers and lipid accumulation. Finally, key transcription factors C/ebpδ and C/ebpα, part of the adipogenic transcriptional cascade, were up-regulated at III two and six hours post-treatment by TMBPF. BPA also up-regulated C/ebpδ at two hours post-treatment. Though the adipogenic effects have become apparent for some of these analogues, the mechanism by which they elicit their effects remains to be discovered. More research is required to deduce the mechanism of action and to provide consensus on what the effects of these replacement bisphenols actually are.

description: In metallic noncentrosymmetric crystals and at surfaces the response of spin currents and charge currents to applied electric fields contains contributions that are second order in the electric field, which are forbidden by symmetry in centrosymmetric systems. Thereby, photocurrents and spin photocurrents can be generated in inversion asymmetric metals by the application of femtosecond laser pulses. We study the laser-induced charge current in the ferromagnetic Rashba model with in-plane magnetization and find that this \textit{magnetic photogalvanic effect} can be tuned to be comparable in size to the laser-induced photocurrents measured experimentally in magnetic bilayer systems such as Co/Pt. Additionally, we show that femtosecond laser pulses excite strong spin currents in the nonmagnetic Rashba model when the Rashba parameter is large.

description: Driven by the need to find alternatives to control H. pylori infections, this work describes the development of chitosan-PMLA nanoparticulate systems as carriers for antimicrobial glycolipid. By using a simple ionic gelation method stable nanoparticle was obtained showing an encapsulation efficiency of 73.1 ± 1.3% and an average size of 217.0 ± 15.6 nm for rhamnolipids chitosan-PMLA nanoparticles (RL-CS-NPs). Glycolipid incorporation and particle size were correspondingly corroborated by FT-IR and TEM analysis. Rhamnolipids chitosan nanoparticles (RL-CS-NPs) presented the highest antimicrobial effect towards H. pylori (ATCC 26695) exhibiting a minimal inhibitory concentration of 132 µg/mL and a biofilm inhibition ability of 99%. Additionally, RL-CS-NPs did not interfere with human fibroblasts viability and proliferation under the tested conditions. The results revealed that the RL-CS-NPs were able to inhibit bacterial growth showing adequate cytocompatibility and might become, after additional studies, a valuable approach to fight H. pylori biofilm related-infections.

description: With research data gaining importance, institutions are required to manage research data responsibly. In general, data management plans, DMPs, are required for the confirmation of proper research data management. However, as DMPs are merely  plans,  they cannot be held as evidence of proper research data management. This presentation proposes using data management records, DMRs, to sustain institutional research data governance and materializes the idea by devising an institutional research data management policy of the National Institute of Informatics (NII), hereinafter the policy, around this concept.

The policy was drafted by a Working Group (WG) set up within NII. The WG made it a core principle that the policy should be a manifesto for institutional research data governance which is to be sustained under the partnership of the institution and the researchers. DMRs, along with the DMP set up by researchers for each research project, are to be shared between these two parties. DMPs and DMRs need to align with legal and ethical terms to form the basis of institutional compliance. This thought experiment shows that DMRs can be leveraged to form institutional research data governance. However, it also shows that the setting of DMPs and archiving of DMRs may become of heavy burden for researchers if done manually.

We plan to devise a DMP/DMR tool that will partly automate the setting of DMPs and archiving of DMRs. Toshiyuki Hiraki's presentation will discuss the core function of this tool.

Those interested in DMPs and research data governance should attend the presentation.

description: Methods based on polynomial chaos expansion allow to approximate the behavior of systems with uncertain parameters by deterministic dynamics. These methods are used in a wide range of applications, spanning from simulation of uncertain systems to estimation and control. For practical purposes the exploited spectral series expansion is typically truncated to allow for efficient computation, which leads to approximation errors. Despite the Hilbert space nature of polynomial chaos, there are only a few results in the literature that explicitly discuss and quantify these approximation errors. This work derives error bounds for polynomial chaos approximations of polynomial and non-polynomial mappings. Sufficient conditions are established, which allow investigating the question whether zero truncation errors can be achieved and which series order is required to achieve this. Furthermore, convex quadratic programs, whose argmin operator is a special case of a piecewise polynomial mapping, are studied due to their relevance in predictive control. Several simulation examples illustrate our findings.

description: Molecular testing for targetable driver mutations is fundamental in advanced stage lung cancer. Small diagnostic tissue samples can miss driver mutations and fail to reflect intratumour heterogeneity (ITGH). Liquid biopsies are non-invasive and may better reflect ITGH. Most liquid biopsies are performed in the context of circulating tumour DNA (ctDNA) in plasma but Exhaled Breath Condensate (EBC) shows significant promise as a lung specific liquid biopsy. In this prospective, proof on concept study we carried out targeted Next Generation Sequencing (NGS) on diagnostic tissue samples of 150 patients with a potential diagnosis of lung cancer and compared the results to plasma and EBC for 5 lung cancer associated driver mutations (EGFR, KRAS, PIK3CA, ERBB2, BRAF) using an ultrasensitive PCR technique (UltraSEEK™ Lung Panel on the MassARRAY® System, Agena Bioscience, San Diego, CA, USA). 125/150 (83.3%) patients had tissue confirmed lung cancer. There was a significantly higher failure rate due to unamplifiable DNA in tissue NGS samples (57/125 ,45.6%) compared to plasma (27/125, 21.6%, p=3.212e-05) and EBC (26/125,20.8%, p=1.115e-05). Consequently, NGS and plasma only showed significant correlation for PIK3CA (X2 p=0.032) and BRAF (X2 p=0.021) and there was no significant correlation between tissue NGS and EBC.However, there was significant correlation between plasma and EBC for EGFR (X2p=0.002), KRAS (X2P=0.0004), PIK3CA (X2P=0.0004) and BRAF (X2P=0.0004) as well as the identification of mutations unique to both modalities. The results suggest that EBC is effective in identifying lung cancer mutations using ultrasensitive PCR and has a potential role as an adjunct to plasma-based testing.The research coincided with the outbreak of the COVID-19 pandemic. False negatives from nasopharyngeal swabs (NPS) using reverse transcriptase PCR (RT-PCR) in SARS-CoV-2 are high. Exhaled Breath Condensate (EBC) contains lower respiratory droplets that may improve detection. We performed EBC RT-PCR for SARS-CoV-2 genes ( E,S,N,ORF1ab) on NPS positive (n=16) and NPS negative/clinically positive COVID-19 patients (n=15) using 2 commercial assays. EBC detected SARS-CoV-2 in 93.5% (29/31) of cases using 4 genes. Pre SARS-CoV-2 era controls (n=14) were all negative. EBC was positive in NPS negative/clinically positive patients in 66.6% (10/15) using the identical E/S assay used for NPS, 73.3% (11/15) using the N/ORF1ab assay and 14/15 (93.3%) combined.

description: To achieve successful communication, people should decode not only the literal meaning of an utterance, but also the intended meanings conveyed by the speaker. In the present study, event-related potential (ERP) technique was used to explore how working memory capacity modulates the processes of indirect replies comprehension. Conversations of Speaker A and Speaker B were constructed. Speaker A’s question renders Speaker B’s reply to be either direct or indirect replies. Participants of high and low working memory span were instructed to read for comprehension. Our results showed that for the high span group, indirect replies elicited a larger P200, a larger P300 and a larger delayed Late Positive Component (LPC) compared with direct replies. While for the low span group, only a delayed LPC effect was elicited by indirect replies. These findings provide evidence that readers’ working memory capacity modulates the early detection and immediate processing of indirect replies.

description: We cannot operate the whole image directly in some applications like image recognition or image compression because it is inefficient method. Therefore, before recognition or compression, many image segmentation algorithms were suggested to segment an image. Image segmentation operation is to rate or cluster an image into many regions depending on the feature of image. A hybrid image compression algorithm is suggested in this paper which segments the image into background and foreground parts and after that compresses the foreground image by using DCT technique. The foreground image is provided more importance than the background region. The color based segmentation method is used to segment image. The observed parameters are compression ratio (CR), mean square error (MSE), and peak signal to noise ratio (PSNR). The goal is to maximize the CR while preserving images' information. The foreground image has a good quality in this the proposed hybrid method.

description: Matching images and sentences demands a fine understanding of both modalities. In this paper, we propose a new system to discriminatively embed the image and text to a shared visual-textual space. In this field, most existing works apply the ranking loss to pull the positive image / text pairs close and push the negative pairs apart from each other. However, directly deploying the ranking loss is hard for network learning, since it starts from the two heterogeneous features to build inter-modal relationship. To address this problem, we propose the instance loss which explicitly considers the intra-modal data distribution. It is based on an unsupervised assumption that each image / text group can be viewed as a class. So the network can learn the fine granularity from every image/text group. The experiment shows that the instance loss offers better weight initialization for the ranking loss, so that more discriminative embeddings can be learned. Besides, existing works usually apply the off-the-shelf features, i.e., word2vec and fixed visual feature. So in a minor contribution, this paper constructs an end-to-end dual-path convolutional network to learn the image and text representations. End-to-end learning allows the system to directly learn from the data and fully utilize the supervision. On two generic retrieval datasets (Flickr30k and MSCOCO), experiments demonstrate that our method yields competitive accuracy compared to state-of-the-art methods. Moreover, in language based person retrieval, we improve the state of the art by a large margin. The code has been made publicly available.

description: This paper shows that nickel nanowires of length 11µm and diameters 800 and 15nm were grown within the pores of nuclear track polycarbonate membrane by electrodepositing nickel. Surface morphology and crystallographic structure of the deposited nanowires was investigated using SEM, TEM and XRD respectively. It is found that low current density gives good result, while high current density leads to the formation of curled nanowires. Fabricated nanowires were further investigated for electrical properties and found that nanowires obey ohm’s law. Through structural characterization it has been observed that the fabricated nanowires posses FCC lattice structure.

description: Silicene, a 2D analogue of graphene, has spurred a tremendous research interest in the scientific community for its unique properties essential for next generation electronic devices. In this work, for the first time, we present a molecular dynamics (MD) investigation to determine the fracture strength and toughness of nanocrystalline silicene (nc silicene) sheet of varied grain size and pre existing crack length at room temperature. Our results suggest that the transition from an inverse pseudo Hall Petch to a pseudo Hall Petch behavior in nc silicene occurs at a critical grain size of 17.32 nm. This phenomenon is also prevalent in nanocrystalline graphene. However, nc silicene with pre existing cracks exhibits anomalous crack propagation and fracture toughness behaviour. We have observed two distinct types of failure mechanisms (crack sensitive and insensitive failure) and devised the mechanophysical conditions under which they occur. Fracture toughness calculated from both Griffiths theory and MD simulations indicate that the former overpredicts the fracture toughness of nc silicene. The most striking outcome, however, is that despite the presence of a pre existing crack, the crack sensitivity of nc silicene is found to be dependent on the grain size and their orientations. This study is the first direct comparison of atomistic simulations to the continuum theories to predict the anomalous behaviour in deformation and failure mechanisms of nc silicene.
