Abstract
The differences in the luminescence intensities of up-conversion β-NaYF4 : Er3+, Yb3+ particles synthesised by the hydrothermal method under various synthesis conditions are studied. The results of the study lead to the conclusion that in order to achieve the maximum luminescence intensity in such particles, it is necessary to use ammonium fluoride and a medium with pH = 3. In this case, the length of the particles increases, up to the formation of rod-shaped particles. Based on the data on the size of the coherent scattering region and on microstresses, we can assume that the particles are polycrystals. At the same time, limiting the size of the coherent scattering region is possible due to the defective structure. When the nanoparticles are synthesised in a medium with pH = 3, hydrolysed regions containing OH groups are formed on the crystallite surface. The presence of these groups does not affect the intensity of up-conversion luminescence of submicron-size particles.

AbstractExternal load influences internal load in resistance training (RT). The purpose of the present study was to compare the total volume‐load, perceptual and stress responses during three different RT protocols. Twelve resistance‐trained men completed three different RT protocols with the back squat and bench press exercises: (1) power (POW) (5 sets of 6 repetitions at 50%1RM, 2‐min of rest), (2) hypertrophy (HYP) (5 sets‐to‐failure at 75%1RM, 2‐min of rest), and (3) strength (STR) (5 sets‐to‐failure at 90%1RM, 3‐min of rest). Volume‐load (kg × reps.), session rating of perceived exertion (sRPE), training impulse (TRIMP; reps. × sRPE), cortisol, immunoglobulin A (IgA), lactate, and creatine kinase (CK) were assessed before and/or after the sessions. HYP was the most demanding session in terms of volume‐load (p < 0.001), TRIMP (p < 0.001), cortisol (p = 0.001), lactate (p < 0.001), and CK (p = 0.001). Despite POW exhibited a greater volume‐load than STR (p = 0.016), the latter exhibiting a greater sRPE (p < 0.001), and a greater post‐session CK (p = 0.05). However, the TRIMP of STR and POW were not statistically different (152 vs. 260 AU; p = 0.089). These specific responses could be meditated by the presence of muscular failure. When pooling all the sessions, significant correlations were revealed among external and internal stress markers (r = 0.35–0.80; p ≤ 0.05). The use of TRIMP could be recommended as a simple and valid monitoring tool which integrates into a single parameter the internal and the external loads of RT sessions.
A multi-stratal perspective on circumstantial meaning
Authors: Dreyfus Shoshana , Hao Jing 
Published: February 2020

ABSTRACT
This paper provides a “broader” understanding of what is previously known from a grammatical perspective as “circumstantial meaning” or circumstantiation. This “broader” perspective takes into account more abstract meanings beyond grammar, considering both field (at the register stratum) and discourse semantics, in addition to lexicogrammar. The paper shows how the lexicogrammar alone is not able to adequately account for the meaning potential of “circumstantial meaning”, and how by examining this region of meaning from three strata, a fuller account of circumstantial meaning is made possible. A richer account of circumstantial meaning is necessary because, while circumstances may be considered structurally peripheral, earlier explorations of circumstantial meaning show that this area of meaning often makes important contributions to the register of any given text and to the building of disciplinary knowledge. This exploration is demonstrated through two texts: a student’s high scoring piece of creative writing from the subject of English in the final year of schooling and a synopsis of a history book on the Chinese fishing industry in colonial Australia. These texts reveal the significantly different ways in which circumstantial meanings are used in different subject areas – i.e., to contribute to setting up an “ambience” in literary texts and to developing knowledge in history.

Published: February 2020

Abstract
We investigate the properties of a trace-gas sensing scheme based on Rydberg excitations at the example of an idealized model system. Rydberg states in thermal rubidium (Rb) are created using a 2-photon cw excitation. These Rydberg-excited atoms ionize via collisions with a background gas of nitrogen (N2). The emerging charges are then measured as an electric current, which is on the order of several picoampere. Due to the 2-photon excitation, this sensing method has a large intrinsic selectivity combined with a promising sensitivity of 10 ppb at an absolute concentration of 1 ppm. The determination of the detection limit is limited by the optical reference measurement but is at least 500 ppb.
Numerical simulation of flux jump behavior in REBaCuO ring bulks with an inhomogeneous Jc profile during pulsed-field magnetization

Published: February 2020

Abstract
We have investigated the electromagnetic and thermal properties of a REBaCuO ring bulk with an inhomogeneous critical current density, J
c, profile during pulsed field magnetization (PFM) using a numerical simulation and compared those to a bulk with a homogeneous J
c profile. A notch was introduced in the bulk periphery, which was assumed as a crack existing in the actual bulk material. A sudden flux penetration (flux jump) took place through the notch area and as a result, a large temperature rise also took place around this notch. Consequently, the final trapped field profile was simulated to be a ‘C-shaped profile’, which qualitatively reproduced our previous experimental results. The size and position dependences of the notch on the flux penetration behaviour were also simulated, in which a larger and outer notch promotes the flux jump phenomenon easily. On the other hand, in the homogeneous model, under the same conditions, no flux jump phenomenon was observed. These results suggest that the imperfection in the bulk can be a possible starting point of the flux jump. The electromagnetic and thermal hoop stresses were also simulated in the ring bulk during PFM, in which the electromagnetic stress and the thermal stress were both observed to be lower than the fracture strength of the bulk material. This provides good evidence that the experimentally observed ‘C-shaped profile’ results from the flux jump rather than the fracture of the bulk.
Distributed quantum sensing enhanced by continuous-variable error correction
Authors: Zhuang Quntao , Preskill John , Jiang Liang 
Published: February 2020

Abstract
A distributed sensing protocol uses a network of local sensing nodes to estimate a global feature of the network, such as a weighted average of locally detectable parameters. In the noiseless case, continuous-variable (CV) multipartite entanglement shared by the nodes can improve the precision of parameter estimation relative to the precision attainable by a network without shared entanglement; for an entangled protocol, the root mean square estimation error scales like 1/M with the number M of sensing nodes, the so-called Heisenberg scaling, while for protocols without entanglement, the error scales like

M

. However, in the presence of loss and other noise sources, although multipartite entanglement still has some advantages for sensing displacements and phases, the scaling of the precision with M is less favorable. In this paper, we show that using CV error correction codes can enhance the robustness of sensing protocols against imperfections and reinstate Heisenberg scaling up to moderate values of M. Furthermore, while previous distributed sensing protocols could measure only a single quadrature, we construct a protocol in which both quadratures can be sensed simultaneously. Our work demonstrates the value of CV error correction codes in realistic sensing scenarios.

Published: February 2020

Abstract
We consider a binary self-attractive Bose–Einstein condensate with Rashba spin–orbit coupling (SOC) in two-dimensional (2D) free space. The formation, stability, and dynamics of vector bright solitons are elucidated through numerical analysis and variational approximation. It is found that dynamically stabilized vector bright solitons can be formed in 2D free space with appropriate parameters and ramp schemes, and its motional trajectory and stability show nontrivial behavior and strong dependence on the direction of the force generated by the SOC. Finally, the case of the periodic modulation of SOC is discussed, and an experimental protocol is also given.

Investigate quality factor of single tuned passive filter to reduce harmonic of LED lamp
Authors: Sarwono Edi , Apriaskar Esa , Azis Salim Nur 
Published: February 2020

Abstract
The use of LED energy-saving lamps is proliferating in the world and ranging from homes, offices to government buildings. The main reason for this is because LED lights have relatively small electrical power consumption. Behind the advantage of saving energy, it turns out that LED lights have a high level of harmonic. Passive filter is recommended to eliminate harmonic. The Quality factor (Q) of a filter will determine its performance. If the Q value is significant, the value of R will be smaller, and the quality of the filter will also be getting better because the energy used by the filter is lowering. It indicates that the heat losses of the filter are small. This work has tested four single tuned passive filter designs on X brand LED lamps with nominal power values of 3W, 4W, and 7W. The inductor values (L) tested were 65mH, 78mH, 91mH, and 115mH, respectively. The test results show that the total harmonic distortion (THD) of voltage on the X brand LED lights does not exceed the IEEE 519-2014 standard limit which is a maximum of 5%, because the highest harmonic voltage is 2.7%. While the highest total harmonic distortion (THD) of current in the LED lamps tested was 154%. The results of installing the first filter (L = 65mH) can reduce THD current up to 90.91%, the second filter (L = 78mH) reduces THD current up to 89.81%, the third filter (L = 91mH) reduces THD current up to 89.57%, while the fourth filter (L = 115mH) reduces THD current up to 86.86%.

Abstract
Land use is a form of human intervention inland to meet the needs of both material needs and spiritual needs. Land use analysis is important for agricultural planning, urbanization and environmental studies. Remote-sensing data and GIS are an appropriate tool for the assessment of the global land-use change and environmental monitoring because of its spatial and temporal coverage capabilities. The change detection and assessment of land use using geospatial information allow the user to monitor land user over the large area and over a period of time. This study aims to classify land use in Ponorogo using Landsat 8 imagery. The normalized difference vegetation index (NDVI) is used for the mapping of changes in the land cover. In this study the NDVI based classification has indicated about significant change in land use between year 2015 and 2017. The major change has been found in areas with dense vegetation such as forest, farm, where about 4.22% of areas have been degraded between year 2015 and 2017.

Abstract
The present study investigates various effects of MEMS-based microfluidic fuel cell on the performance of direct formic acid microfluidic fuel cells that breathe air as an oxidant. A miniaturized fuel cell of the structure and design of a typical T-shaped air- breathing Direct Formic Acid Fuel Cell with micro channel is 1.5 mm x 25 mm in width multiply length. Both anode and cathode electrode having a width and length of 0.6 mm and 20 mm, respectively, with an electrode spacing of 0.3 mm. An air-breathing microfluidic fuel cell having a 0.6 mm in width and 20 mm in length that is placed on cathode GDE down-side. In such systems for the fluid delivery, both formic acid (0.5 M) as a fuel solution mixing sulfuric acid (0.5 M) at a node channel side and as an electrolyte used sulfuric acid (0.5 M) place take on the cathode channel side are injected together into the end of the channel outlet by two syringe pumps. Firstly, a three-dimensional microfluidic fuel cell model was established using Computational Fluids Dynamics to simulate the fuel cell performance. Further, both V-I curves obtained from simulation and published experimental data under similar operating condition were compared to assure the validity of the simulation. Modelling the transport and electrochemical phenomena were described with hydrodynamic equations, the porous media flow, mass transport, electrochemical reaction and charge equation. The porous media flow in the gas diffusion layer was described by Brinkman equation. The Butler-Volmer equations were applied to get the V-I-P curves. An anode electrode surface performance, respectively, is presented.

AbstractAimsThe cardioprotective effects of human induced pluripotent stem cell-derived cardiovascular progenitor cells (CPC) are largely mediated by the paracrine release of extracellular vesicles (EV). We aimed to assess the immunological behaviour of EV-CPC, which is a prerequisite for their clinical translation.Methods and resultsFlow cytometry demonstrated that EV-CPC expressed very low levels of immune relevant molecules including HLA Class I, CD80, CD274 (PD-L1), and CD275 (ICOS-L); and moderate levels of ligands of the natural killer (NK) cell activating receptor, NKG2D. In mixed lymphocyte reactions, EV-CPC neither induced nor modulated adaptive allogeneic T cell immune responses. They also failed to induce NK cell degranulation, even at high concentrations. These in vitro effects were confirmed in vivo as repeated injections of EV-CPC did not stimulate production of immunoglobulins or affect the interferon (IFN)-γ responses from primed splenocytes. In a mouse model of chronic heart failure, intra-myocardial injections of EV-CPC, 3 weeks after myocardial infarction, decreased both the number of cardiac pro-inflammatory Ly6Chigh monocytes and circulating levels of pro-inflammatory cytokines (IL-1α, TNF-α, and IFN-γ). In a model of acute infarction, direct cardiac injection of EV-CPC 2 days after infarction reduced pro-inflammatory macrophages, Ly6Chigh monocytes, and neutrophils in heart tissue as compared to controls. EV-CPC also reduced levels of pro-inflammatory cytokines IL-1α, IL-2, and IL-6, and increased levels of the anti-inflammatory cytokine IL-10. These effects on human macrophages and monocytes were reproduced in vitro; EV-CPC reduced the number of pro-inflammatory monocytes and M1 macrophages, while increasing the number of anti-inflammatory M2 macrophages.ConclusionsEV-CPC do not trigger an immune response either in in vitro human allogeneic models or in immunocompetent animal models. The capacity for orienting the response of monocyte/macrophages towards resolution of inflammation strengthens the clinical attractiveness of EV-CPC as an acellular therapy for cardiac repair.

Published: February 2020

Abstract
Runt-related transcription factor-1 (RUNX1), also known as acute myeloid leukaemia 1 protein (AML1), is a member of the core-binding factor family of transcription factors which modulate cell proliferation, differentiation, and survival in multiple systems. It is a master-regulator transcription factor, which has been implicated in diverse signalling pathways and cellular mechanisms during normal development and disease. RUNX1 is best characterized for its indispensable role for definitive haematopoiesis and its involvement in haematological malignancies. However, more recently RUNX1 has been identified as a key regulator of adverse cardiac remodelling following myocardial infarction. This review discusses the role RUNX1 plays in the heart and highlights its therapeutic potential as a target to limit the progression of adverse cardiac remodelling and heart failure.

Abstract

Background
Although a majority of patients with PSC have colitis [PSC-IBD; primary sclerosing cholangitis-inflammatory bowel disease], this is phenotypically different from ulcerative colitis [UC]. We sought to define further the pathophysiological differences between PSC-IBD and UC, by applying a comparative and integrative approach to colonic gene expression, gut microbiota and immune infiltration data.

Methods
Colonic biopsies were collected from patients with PSC-IBD [n = 10], UC [n = 10], and healthy controls [HC; n = 10]. Shotgun RNA-sequencing for differentially expressed colonic mucosal genes [DEGs], 16S rRNA analysis for microbial profiling, and immunophenotyping were performed followed by multi-omic integration.

Results
The colonic transcriptome differed significantly between groups [p = 0.01]. Colonic transcriptomes from HC were different from both UC [1343 DEGs] and PSC-IBD [4312 DEGs]. Of these genes, only 939 had shared differential gene expression in both UC and PSC-IBD compared with HC. Imputed pathways were predominantly associated with upregulation of immune response and microbial defense in both disease cohorts compared with HC. There were 1692 DEGs between PSC-IBD and UC. Bile acid signalling pathways were upregulated in PSC-IBD compared with UC [p = 0.02]. Microbiota profiles were different between the three groups [p = 0.01]; with inferred function in PSC-IBD also being consistent with dysregulation of bile acid metabolism. Th17 cells and IL17-producing CD4 cells were increased in both PSC-IBD and UC when compared with HC [p &lt; 0.05]. Multi-omic integration revealed networks involved in bile acid homeostasis and cancer regulation in PSC-IBD.

Conclusions
Colonic transcriptomic and microbiota analysis in PSC-IBD point toward dysregulation of colonic bile acid homeostasis compared with UC. This highlights important mechanisms and suggests the possibility of novel approaches in treating PSC-IBD.
