Analysis of Fracture Parameters in Concrete by Using ABAQUS Software

It is commonly accepted that there is a size effect on the nominal resistances of quasi-brittle materials such as cementitious materials. This effect must be taken into account in the design of the ultimate behavior of concrete structures in order to avoid damage and crack openings. These parameters are frequently used to study the behavior of concrete and to characterize the durability of structures. Different theories exist in the literature to describe the size effect. Among them, we find the deterministic theory of Bazant where fracture energy is considered independent of the size and it is assumed that at peak load, the crack length is proportional to the size of the specimen. In this work, attention is paid to investigate numerically, the relationship between crack openings and length, and the size of the specimens. Various fracture parameters have also been studied by validating with the existing work for a concrete of grade M35 grade of concrete based on the RILEM standards. The present study shows the determination of fracture parameters of beams size-ranging from 100-400 mm using ABAQUS. Then analyzed the size-effect behavior of various fracture parameters obtained from different sizes of the beam.
MEDIUM-TERM PRESERVATION OF Dianthus trifasciculatus Kit ssp. parviflorus THROUGH MINIMAL CULTURES

The species taking in our study, Dianthus trifasciculatus ssp. parviflorus is a critically endangered taxon, in vitro studies being useful for ex situ preservation purpose. Owing to in vitro rapid growth and proliferation, it is important to establish a medium-term conservation protocol based on minimal cultures. Several factors were tested concerning the ability to reduce the growth of tissues cultures and to maintain regeneration capacity. Mannitol and PEG 4000 were proven to be the most suitable for the establishment of minimal cultures. Regenerants from three years old minimal cultures maintained in the presence of mannitol were analysed concerning isoenzymes spectrum for peroxidase, esterases, alkaline phosphatases and catalases. Biochemical analyses have shown that peroxidases (POX) and catalases (CAT) are sensitive to the culture conditions (the maintenance in presence of osmolytes). The treatment with 6% mannitol influenced the intensity of the bands analysed in the case of rooted plants even after 2 months of culture in the absence of any osmolyte. The analysis of esterases and alkaline phosphatases spectra has shown the regenerants identity.
neuromusculoskeletal pain syndromes are associated with hyper-and hypothyroidism ?

Author Title Number of Pages Date Charlotte Nelin Which neuromusculoskeletal pain syndromes are associated with hyper-and hypothyroidism? 49 pages 5th March 2020 Degree Bachelor of Healthcare Degree Programme Osteopathy Instructors Niklas Sinderholm Sposato, M. Sc. D.O. Project supervisor The purpose of this study was to investigate which neuromusculoskeletal pain syndromes could be associated with hyper-and hypothyroidism, both before diagnosis of the thyroid disorder and during treatment. From a clinical and osteopathic perspective, these associations are important to be aware of in order to provide the best possible care. This literature review was a quantitative study, based on searches performed on six databases, which focused on the neuromusculoskeletal complaints and diagnoses in patients before or in connection with their thyroid disorder diagnosis, or as a residual symptom during their treatment. The results showed that neurological, muscular or skeletal symptoms could be the only manifestations of a thyroid disorder, that the majority of patients with hyper-and hypothyroidism have neuromuscular complaints, and many suffer from clinical weakness and neuropathies. The most commonly associated diagnoses were carpal tunnel syndrome, adhesive capsulitis and Dupuytren’s contracture. For hyperthyroidism, osteopenia and osteoporosis, tremor and hyperreflexia could be relevant, for hypothyroidism the separate diagnoses of hypothyroid myopathy and hypothyroid arthropathy along with several different skeletal and joint manifestations were noteworthy. The findings also showed that a large group of these patients suffer from residual symptoms related to neuromusculoskeletal issues. The identification and recognition of neuromusculoskeletal signs and symptoms which could be either the initial manifestation of a thyroid disorder or an associated issue are of importance to provide fast and correct treatment. Further research into optimal treatment methods would be warranted to decrease the residual symptoms experienced by far too many patients, especially those with hypothyroidism.
Angelina RUSINEK THE TRADITION OF FIELD THEORY AND THE STUDY OF LEXICAL SEMANTIC CHANGE

Language has always been somewhat of a riddle to its students and thus, keeping them engrossed in its issues, it continues to be the subject matter of their research, polemics and methodological dispute. Obviously, any natural language tends to change both in space and time or – in other words – it is in a state of constant flux, both quantitative and qualitative. It is the examination of the structure of the vocabulary that stands for the central preoccupation of the present paper, the major objective of which is to outline the development of the field theory, as well as to tackle the problem of how the field theory has been implemented in the study of historical semantic changes within various lexical fields over time.
Cytotoxicity Effect of 5-fluorouracil and bee products on the HTC-116 Human colon Cancer Cell Line in vitro

Introduction: Tumoris one of the most irresistible diseases all over the world, comprising large group of disorders distinguished by unmanaged cellular proliferation. Nowadays, there is an increased concern in the clinical application of natural products as an efficient, safe, and economic therapeutic alternative. Apitherapy or honey bee products therapy, was used to control different illness including cancer. Aim: The main target from this work was to study in vitro the potential cytotoxic impacts of honey bee products (RJ, H, PG, and mix) combined with or without 5-Fluorouracil (5-FU) against viability of colorectal cancer cells (HTC116). Material and methods: Human colon cancer cell line HCT116 were cultured in RPMI 1640 medium, enriched with 10% FBS and antibiotics. The cells were incubated under suitable environmental conditions (5% CO2 and 95% air at 37°C and high humidity). Samples with cell viability of 95% and above were selected for use throughout this study. The cytotoxicity of 5-FU combination was tested against HTC-116 cells by sulforhodamine B (SRB) assay. Results: Treatment of in vitro HTC116 cultured cells with 5-FU alone resulted in elevation in IC50 value (6.94 uM, R-value 4.24%), in comparison with treatment with one or more of bee products (IC50 >100 uM/ml. In contrast, treatment with 5-Fu and supplementation with one or more of Honey products (RJ, H, PG & Mix), resulted in a significant decrease in IC50 value, which reached 3.39, 2.59, 1.9 and 2.04 uM, respectively. Therefore, during treatment with 5-FU, combine with one of honey products (RJ, H, PG) or their combination induced significant decline in cell viability as matched with the control (untreated) group, and the capability of 5-FUto affect the growth of HCT 116 cells in vitro was more enhanced only when the drug was supplemented with bee products. In conclusion, The combination of a single dose of one of Royall jelly, honey, pollen grains or their combinations with different concentrations of 5-FU confirmed significant suppressive action on HCT 116 viability in contrast to 5-FU alone at the same dosage. The obtained data proposed that bee products (RJ, H & PG) has a synergistic cytotoxic outcome with 5-FU in HCT 116 cell lines in vitro. [Lina Kurdi and Fatimah Alhusayni.

Decentralized Heterogeneous Multi-Player Multi-Armed Bandits With Non-Zero Rewards on Collisions

We consider a fully decentralized multi-player stochastic multi-armed bandit setting where the players cannot communicate with each other and can observe only their own actions and rewards. The environment may appear differently to different players, <inline-formula> <tex-math notation="LaTeX">$\textit {i.e.}$ </tex-math></inline-formula>, the reward distributions for a given arm are heterogeneous across players. In the case of a collision (when more than one player plays the same arm), we allow for the colliding players to receive non-zero rewards. The time-horizon <inline-formula> <tex-math notation="LaTeX">$T$ </tex-math></inline-formula> for which the arms are played is <italic>not</italic> known to the players. Within this setup, where the number of players is allowed to be greater than the number of arms, we present a policy that achieves near order-optimal expected regret of order <inline-formula> <tex-math notation="LaTeX">$O(\log ^{1 + \delta } T)$ </tex-math></inline-formula> for <inline-formula> <tex-math notation="LaTeX">$\delta >0$ </tex-math></inline-formula> (however small) over a time-horizon of duration <inline-formula> <tex-math notation="LaTeX">$T$ </tex-math></inline-formula>.
Ellipsis Resolution as Question Answering: An Evaluation

Most, if not all forms of ellipsis (e.g., so does Mary) are similar to reading comprehension questions (what does Mary do), in that in order to resolve them, we need to identify an appropriate text span in the preceding discourse. Following this observation, we present an alternative approach for English ellipsis resolution relying on architectures developed for question answering (QA). We present both single-task models, and joint models trained on auxiliary QA and coreference resolution datasets, clearly outperforming the current state of the art for Sluice Ellipsis (from 70.00 to 86.01 F1) and Verb Phrase Ellipsis (from 72.89 to 78.66 F1).
Generating (Formulaic) Text by Splicing Together Nearest Neighbors

We propose to tackle conditional text generation tasks, especially those which require generating formulaic text, by splicing together segments of text from retrieved “neigh-bor” source-target pairs. Unlike recent work that conditions on retrieved neighbors in an encoder-decoder setting but generates text token-by-token, left-to-right, we learn a policy that directly manipulates segments of neighbor text (i.e., by inserting or replacing them) to form an output. Standard techniques for training such a policy require an oracle derivation for each generation, and we prove that ﬁnding the shortest such derivation can be reduced to parsing under a particular weighted context-free grammar. We ﬁnd that policies learned in this way allow for interpretable table-to-text and headline generation that is competitive with or better than state-of-the-art autoregressive token-level policies in terms of automatic metrics, and moreover allows for faster decoding.
No More Handshaking: How have COVID-19 pushed the expansion of computer-mediated communication in Japanese idol culture?

In Japanese idol culture, meet-and-greet events where fans were allowed to handshake with an idol member for several seconds were regarded as its essential component until the spread of COVID-19. Now, idol groups are struggling in the transition of such events to computer-mediated communication because these events had emphasized meeting face-to-face over communicating, as we can infer from their length of time. I anticipated that investigating this emerging transition would provide implications because their communication has a unique characteristic that is distinct from well-studied situations, such as workplace communication and intimate relationships. Therefore, I first conducted a quantitative survey to develop a precise understanding of the transition, and based on its results, had semi-structured interviews with idol fans about their perceptions of the transition. The survey revealed distinctive approaches, including one where fans gathered at a venue but were isolated from the idol member by an acrylic plate and talked via a video call. Then the interviews not only provided answers to why such an approach would be reasonable but also suggested the existence of a large gap between conventional offline events and emerging online events in their perceptions. Based on the results, I discussed how we can develop interaction techniques to support this transition and how we can apply it to other situations outside idol culture, such as computer-mediated performing arts.
Fast deep neural correspondence for tracking and identifying neurons in C. elegans using semi-synthetic training

We present an automated method to track and identify neurons in C. elegans, called ‘fast Deep Neural Correspondence’ or fDNC, based on the transformer network architecture. The model is trained once on empirically derived semi-synthetic data and then predicts neural correspondence across held-out real animals. The same pre-trained model both tracks neurons across time and identifies corresponding neurons across individuals. Performance is evaluated against hand-annotated datasets, including NeuroPAL (Yemini et al., 2021). Using only position information, the method achieves 79.1% accuracy at tracking neurons within an individual and 64.1% accuracy at identifying neurons across individuals. Accuracy at identifying neurons across individuals is even higher (78.2%) when the model is applied to a dataset published by another group (Chaudhary et al., 2021). Accuracy reaches 74.7% on our dataset when using color information from NeuroPAL. Unlike previous methods, fDNC does not require straightening or transforming the animal into a canonical coordinate system. The method is fast and predicts correspondence in 10 ms making it suitable for future real-time applications.
On geometrically finite degenerations I: boundaries of main hyperbolic components

In this paper, we develop a theory on the degenerations of Blaschke products $\mathcal{B}_d$ to study the boundaries of hyperbolic components. We give a combinatorial classification of geometrically finite polynomials on the boundary of the main hyperbolic component $\mathcal{H}_d$ containing $z^d$. We show the closure $\overline{\mathcal{H}_d}$ is not a topological manifold with boundary for $d\geq 4$ by constructing self-bumps on its boundary.
NB-IoT Random Access for Nonterrestrial Networks: Preamble Detection and Uplink Synchronization

The satellite component is recognized as a promising solution to complement and extend the coverage of future Internet of Things (IoT) terrestrial networks (TNs). In this context, a study item to integrate satellites into narrowband-IoT (NB-IoT) systems has been approved within the 3rd Generation Partnership Project (3GPP) standardization body. However, as NB-IoT systems were initially conceived for TNs, their basic design principles and operation might require some key modifications when incorporating the satellite component. These changes in NB-IoT systems, therefore, need to be carefully implemented in order to guarantee a seamless integration of both TN and nonterrestrial network (NTN) for a global coverage. This article addresses this adaptation for the random access (RA) step in NB-IoT systems, which is in fact the most challenging aspect in the NTN context, for it deals with multiuser time-frequency synchronization and timing advance for data scheduling. In particular, we propose an RA technique which is robust to typical satellite channel impairments, including long delays, significant Doppler effects, and wide beams, without requiring any modification to the current NB-IoT RA waveform. Performance evaluations demonstrate the proposal’s capability of addressing different NTN configurations recently defined by 3GPP for the 5G new radio system.
Symmetry-resolved dynamical purification in synthetic quantum matter

When a quantum system initialized in a product state is subjected to either coherent or incoherent dynamics, the entropy of any of its connected partitions generically increases as a function of time, signalling the inevitable spreading of (quantum) information throughout the system. Here, we show that, in the presence of continuous symmetries and under ubiquitous experimental conditions, symmetry-resolved information spreading is inhibited due to the competition of coherent and incoherent dynamics: in given quantum number sectors, entropy decreases as a function of time, signalling dynamical purification. Such dynamical purification bridges between two distinct short and intermediate time regimes, characterized by a log-volume and log-area entropy law, respectively. It is generic to symmetric quantum evolution, and as such occurs for different partition geometry and topology, and classes of (local) Liouville dynamics. We then develop a protocol to measure symmetry-resolved entropies and negativities in synthetic quantum systems based on the random unitary toolbox, and demonstrate the generality of dynamical purification using experimental data from trapped ion experiments [Brydges et al., Science 364, 260 (2019)]. Our work shows that symmetry plays a key role as a magnifying glass to characterize many-body dynamics in open quantum systems, and, in particular, in noisy-intermediate scale quantum devices.
1st Place Solution to ECCV-TAO-2020: Detect and Represent Any Object for Tracking

We extend the classical tracking-by-detection paradigm to this tracking-any-object task. Solid detection results are first extracted from TAO dataset. Some state-of-the-art techniques like \textbf{BA}lanced-\textbf{G}roup \textbf{S}oftmax (\textbf{BAGS}\cite{li2020overcoming}) and DetectoRS\cite{qiao2020detectors} are integrated during detection. Then we learned appearance features to represent any object by training feature learning networks. We ensemble several models for improving detection and feature representation. Simple linking strategies with most similar appearance features and tracklet-level post association module are finally applied to generate final tracking results. Our method is submitted as \textbf{AOA} on the challenge website. Code is available at https://github.com/feiaxyt/Winner_ECCV20_TAO.
UMG silicon for solar PV: from defects engineering to PV module degradation

Upgraded metallurgical grade silicon (UMG-Si) for photovoltaic (PV) solar applications has been manufactured through the metallurgical route by means of the process developed by Ferrosolar. In an ambitious mass production test, performed in commercial solar cells and modules production lines, the silicon was proven to be appropriate for photovoltaics applications [(Forniés et al., 2019)], reaching, in a conventional production line, up to 20.76% of solar cell efficiency with multicrystalline cells made of 100% UMG silicon. In this paper we present more results from the mentioned massive test. Defect engineering is being applied to improve the bulk lifetime of the UMG wafers and to guide in the identification of the limiting defects in the material. Moreover, the modules produced with 100% UMG silicon solar cells were installed together with the modules produced in the same production line with polysilicon material to assess the degradation of the UMG silicon when compared to polysilicon. After 15 months of outdoor PV generation, the degradation, in terms of Performance Ratio at 25oC (25PR) diminution, has been the same for both types of modules. Additionally, a Life Cycle Assessment (LCA) has been performed for this UMG silicon and state-of-the-art Siemens polysilicon to compare the environmental impact of both silicon feedstocks. The results presented in this paper; chemical analysis of wafers, defect engineering, low degradation, average efficiency obtained in previous results and environmental assessment, lead to a complete study of UMG silicon, confirming its potential to be used as raw material for PV applications.
Stellar Radial Velocities in the Old Open Cluster M67 (NGC 2682). II. The Spectroscopic Binary Population

We present and analyze 120 spectroscopic binary and triple cluster members of the old (4 Gyr) open cluster M67 (NGC 2682). As a cornerstone of stellar astrophysics, M67 is a key cluster in the WIYN Open Cluster Study (WOCS); radial-velocity (RV) observations of M67 are ongoing and extend back over 45 yr, incorporating data from seven different telescopes, and allowing us to detect binaries with orbital periods ≲104 days. Our sample contains 1296 stars (604 cluster members) with magnitudes of 10 ≤ V ≤ 16.5 (about 1.3–0.7 M ⊙), from the giants down to ∼4 mag below the main-sequence turnoff, and extends in radius to 30′ (7.4 pc at a distance of 850 pc, or ∼7 core radii). This paper focuses primarily on the main-sequence binaries, but orbital solutions are also presented for red giants, yellow giants, and sub-subgiants. Out to our period detection limit and within our magnitude and spatial domain, we find a global main-sequence incompleteness-corrected binary fraction of 34% ± 3%, which rises to 70% ± 17% in the cluster center. We derive a tidal circularization period of . We also analyze the incompleteness-corrected distributions of binary orbital elements and masses. The period distribution rises toward longer periods. The eccentricity distribution, beyond P circ, is consistent with a uniform distribution. The mass-ratio distribution is also consistent with a uniform distribution. Overall, these M67 binaries are closely consistent with similar binaries in the galactic field, as well as with the old (7 Gyr) open cluster NGC 188. WOCS. 83.
First-principles feasibility assessment of a topological insulator at the InAs/GaSb interface

First principles simulations are conducted to shed light on the question of whether a two-dimensional topological insulator (2DTI) phase may be obtained at the interface between InAs and GaSb. To this end, the InAs/GaSb interface is compared and contrasted with the HgTe/CdTe interface. Density functional theory (DFT) simulations of these interfaces are performed using a machine-learned Hubbard U correction [npj Comput. Mater. 6, 180 (2020)]. For the HgTe/CdTe interface our simulations show that band crossing is achieved and an inverted gap is obtained at a critical thickness of 5.1 nm of HgTe, in agreement with experiment and previous DFT calculations. In contrast, for InAs/GaSb the gap narrows with increasing thickness of InAs; however the gap does not close for interfaces with up to 50 layers (about 15 nm) of each material. When an external electric ﬁeld is applied across the InAs/GaSb interface, the GaSb-derived valence band maximum is shifted up in energy with respect to the InAs-derived conduction band minimum until eventually the bands cross and an inverted gap opens. Our results show that it may be possible to reach the topological regime at the InAs/GaSb interface under the right conditions. However, it may be chal-lenging to realize these conditions experimentally, which explains the diﬃculty of experimentally demonstrating an inverted gap in InAs/GaSb.
