Authors: Liu Yang , Xing Zuoxia , Chen Zhe , Xu Jian 
Published: August 2021

AbstractIn this article, a new data‐based adaptive dynamic programming algorithm is proposed to solve the optimal control policy for discrete‐time systems with uncertainties. Firstly, for uncertain systems, the corresponding Hamiltonian function is designed, and then the robust adaptive dynamic programming algorithm is obtained. Next, by using the input and output data of the system, the data‐based Bellman equation is constructed, and the data‐based robust adaptive dynamic programming algorithm is derived, which does not require the accurate model of the system. Finally, a simulation example shows the effectiveness of the proposed algorithm.

AbstractObjectiveFamilies of children with cancer undergoing treatment during COVID‐19 pandemic represent a vulnerable population for psychological distress and early identification and remedial measures are imperative for wellbeing of both the children and the caregivers. This article reports the results of assessment of psychological distress in primary caregivers of children with cancer undergoing treatment at a tertiary care center.MethodsPrimary caregivers of children with cancer (≤15 years) taking treatment at our institute during the period of July 2020 to August 2020 were prospectively evaluated for psychological distress using Patient Health Questionnaire‐9 (PHQ‐9) and Generalized Anxiety Disorder‐7 (GAD‐7) tools over a telephonic call. There were 2 cohorts, A and B (50 participants each) depending on whether child was diagnosed with COVID‐19 or not respectively during the study period.ResultsThe assessment tool, PHQ‐9 showed a score of ≥10 in 13% (n = 13) participants (95%CI:7.1%–21.2%) in the entire cohort and in 16% (n = 8, 95%CI:5.8%–26.2%) and 10% (n = 5, 95%CI:1.7%–18.3%) participants in cohort A and cohort B respectively. GAD‐7 showed a score of ≥8 in 18% (n = 18) participants (95%CI:11.0%–27.0%) in the entire cohort and in 20% (n = 10, 95%CI:8.9%–31.1%) and 16% (n = 8, 95%CI:5.8%–26.2%) participants in cohort A and cohort B respectively. All participants were assessed, and supportive psychotherapeutic interventions administered over telephonic call.ConclusionsPrimary caregivers should be assessed and followed up for psychological distress irrespective of other co‐existing factors. Robust support systems built over time could help withstand the exceptional strain of a major surge during a pandemic.

Published: August 2021

With the rapid development of electronic industryelectromagnetic radiation issue has become an inevitably major problem in the industry. At present, LCD have been used in the display scene for various industries, while near‐field radiation issue will occur during the period when LCD is working, In this paper, a co‐simulation method based on SIwave + Designer is proposed to get the simulated result ofnear‐field radiation for both LCD module and driving circuit PCBA, so as to obtain a more optimized design scheme based on the radiation intensity result. The main steps of this method are as follow: import the design file into SI‐Wave, add simulation ports, get s parameters, then import model from SI‐wave into designer, add the actual excitation source, and then return to SIwave to analyze the real radiation distribution. At the same time, the intensity and distribution ofradiation for PCBA (Printed Circuit Board Assembly) are measured by high‐precision probe to verify the effectiveness of the simulation method and the accuracy of the simulation model by comparing the simulation and measured result.In particular, this method is also a general radiation simulation method, which can be extended to the radiation simulation research ofvarious industries.

Published: August 2021

AbstractN‐Doped Graphene Quantum Dots (N‐GQDs) have been extensively investigated owing to their interesting photochemical, and electrochemical properties. However, N‐GQDs have rarely been introduced as catalyst in organic reactions. Herein, NiO/Co3O4 composites with diverse morphologies of hexagonal nanoplates, spherical, irregular nanocubics, and multishape are fabricated using different solvents and pH adjusters. In the following, the catalytic activity of engineered composites was screened, and it demonstrated to be in the order: spherical>hexagonal nanoplate>irregular solid nanocubic>multi‐shape. The uniform spherical morphology makes exposure of a larger part of the reactive facets possible and provides accessible active sites. Next, novel NiO/Co3O4@N‐GQDs spherical composites has been successfully fabricated by cost‐effective, green and straightforward hydrothermal method. Proposed composite was applied as an efficient heterogeneous catalyst for the microwave‐assisted synthesis of new and known indenospiro derivatives. The desired products were formed in excellent yields (88–97 %) within the short reaction time (6–14 min).

Published: August 2021

AbstractResearchers have achieved precise control of the size of quantum dots by using the quantum confinement effect. Rb+ and Cs+ with similar ionic radii have become a new mechanism for researchers to regulate the emission wavelength of quantum dots. However, there are few studies on the performance of codoped quantum dots with ion at present. By adding a saturated solution of RbCl into an organic solution of CsPbBr3, quantum dots doped with Rb+ and Cl− were prepared. The prepared quantum dots realized adjustable emission spectrum (457‐510 nm), stable lattice structure, and good stability under ultraviolet light irradiation. Therefore, double ion doping is a new method to prepare short‐wavelength of quantum dots.

AbstractNew conjugates of daunorubicin with sesquiterpene lactones at the 3′‐amino group of anthracycline were synthesized and their effect on the viability of cell lines (HL60, Jurkat, K562, and A549) was assessed using a resazurin test. The effect on the cell cycle and apoptosis by flow cytometry was studied. The following natural lactones were used for modification: telekin, isotelekin, reynosin, costunolide, dehydrocostuslactone, santamarine and epoxyisoalantolactone. The synthesized conjugates are characterized by a general high toxicity (8…0.14 μM) in relation to tumor cell lines (in some cases, higher than the toxicity of the initial antibiotic), as well as a comparable effect on the cell cycle (arrest in the G2/M‐phase) with a relatively low the effect on the initiation of apoptosis at concentrations close to the IC50.

ABSTRACTObjectiveTo assess the prevalence and morphological appearance of deep endometriosis and ovarian endometrioma using pelvic ultrasound examination in women attending for an early pregnancy assessment.MethodsThis was a prospective observational study set within a dedicated early pregnancy unit. The study included 1341 consecutive women who attended for an early pregnancy assessment for reassurance or because of suspected early pregnancy complications. All women underwent a transvaginal scan to assess the location and viability of their pregnancy. In addition, a detailed examination of pelvic organs was carried out to detect the presence of endometriosis and other gynecological abnormalities. Data analysis was performed using logistic regression and multivariable analysis.ResultsThe prevalence of deep endometriosis and/or ovarian endometrioma in women attending our early pregnancy unit was 4.9% (95% CI, 3.8–6.2%). In 33/66 (50.0% (95% CI, 37.9–62.1%)) women with endometriosis, this was a new diagnosis that was made during their early pregnancy scan. On multivariable analysis, the presence of endometriosis was strongly associated with a history of subfertility (odds ratio (OR), 3.15 (95% CI, 1.63–6.07)) and presence of a congenital uterine anomaly (OR, 5.69 (95% CI, 2.17–14.9)) and uterine fibroids (OR, 2.37 (95% CI, 1.31–4.28)). Morphological changes typical of decidualization were seen in 11/33 (33.3% (95% CI, 17.2–49.4%)) women with ovarian endometrioma and 18/57 (31.6% (95% CI, 19.5–43.7%)) women with deep endometriotic nodules.ConclusionsDeep endometriosis and ovarian endometrioma were present in a significant proportion of women attending for early pregnancy assessment. The prevalence varied depending on a history of subfertility, and therefore is likely to differ significantly among populations, depending on their characteristics. Ultrasound is a useful tool for the detection of endometriosis in early pregnancy and the identification of women who may benefit from specialist antenatal care. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Published: August 2021

AbstractAn ensemble of high‐resolution regional climate model simulation data is used to examine the impacts of climate change on offshore and onshore wind energy generation in Ireland. Two Representative Concentration Pathway (RCP) scenarios (RCP 4.5 and 8.5) are analysed for the mid‐term (2041–2060) and the long‐term (2081–2100) future. Wind energy is projected to decrease (≤2%) overall in future climate scenarios. Changes are evident by mid‐century and are more pronounced by late 21st century, particularly for RCP 8.5 offshore. Seasonally, wind energy is projected to decrease by less than 6% in summer and to increase slightly in winter (up to 1.1%). The distinct changes in different parts of the power curve, presented here for the first time, show a reversed pattern of duration at certain levels of the power curve. In summer, there is an increase of low‐power and a decrease of high‐power generation, whereas during winter, there is a projected increase in the time spent at high power. This could lead to diverse consequences for system operators depending on the season. The impacts of climate change on the duration and frequency of long periods (longer than 24 h) of low‐/high‐power wind energy events in Ireland are also presented. The frequency of low‐power events is projected to increase slightly, especially during summer. Onshore and offshore events are considered separately, demonstrating the complementarity of developing both onshore and offshore wind farms for future energy systems. Regional analysis highlights the benefit of developing a geographically dispersed wind farm network incorporating different local wind conditions.
Massive double copy in three spacetime dimensions
Authors: González Mariana Carrillo , Momeni Arshia , Rumbutis Justinas 
Published: August 2021

Abstract
Recent explorations on how to construct a double copy of massive gauge fields have shown that, while any amplitude can be written in a form consistent with colour-kinematics duality, the double copy is generically unphysical. In this paper, we explore a new direction in which we can obtain a sensible double copy of massive gauge fields due to the special kinematics in three-dimensional spacetimes. To avoid the appearance of spurious poles at 5-points, we only require that the scattering amplitudes satisfy one BCJ relation. We show that the amplitudes of Topologically Massive Yang-Mills satisfy this relation and that their double copy at three, four, and five-points is Topologically Massive Gravity.
Dynamical spin chains in 4D $$ \mathcal{N} $$ = 2 SCFTs

Published: August 2021

Abstract
This is the first in a series of papers devoted to the study of spin chains capturing the spectral problem of 4d $$ \mathcal{N} $$
N
= 2 SCFTs in the planar limit. At one loop and in the quantum plane limit, we discover a quasi-Hopf symmetry algebra, defined by the R-matrix read off from the superpotential. This implies that when orbifolding the $$ \mathcal{N} $$
N
= 4 symmetry algebra down to the $$ \mathcal{N} $$
N
= 2 one and then marginaly deforming, the broken generators are not lost, but get upgraded to quantum generators. Importantly, we demonstrate that these chains are dynamical, in the sense that their Hamiltonian depends on a parameter which is dynamically determined along the chain. At one loop we map the holomorphic SU(3) scalar sector to a dynamical 15-vertex model, which corresponds to an RSOS model, whose adjacency graph can be read off from the gauge theory quiver/brane tiling. One scalar SU(2) sub-sector is described by an alternating nearest-neighbour Hamiltonian, while another choice of SU(2) sub-sector leads to a dynamical dilute Temperley-Lieb model. These sectors have a common vacuum state, around which the magnon dispersion relations are naturally uniformised by elliptic functions. Concretely, for the ℤ2 quiver theory we study these dynamical chains by solving the one- and two-magnon problems with the coordinate Bethe ansatz approach. We confirm our analytic results by numerical comparison with the explicit diagonalisation of the Hamiltonian for short closed chains.
Validating the Earth’s core using atmospheric neutrinos with ICAL at INO
Authors: Kumar Anil , Agarwalla Sanjib Kumar 
Published: August 2021

Abstract
The Iron Calorimeter (ICAL) detector at the proposed India-based Neutrino Observatory (INO) aims to detect atmospheric neutrinos and antineutrinos separately in the multi-GeV range of energies and over a wide range of baselines. By utilizing its charge identification capability, ICAL can efficiently distinguish μ− and μ+ events. Atmospheric neutrinos passing long distances through Earth can be detected at ICAL with good resolution in energy and direction, which enables ICAL to see the density-dependent matter oscillations experienced by upward-going neutrinos in the multi-GeV range of energies. In this work, we explore the possibility of utilizing neutrino oscillations in the presence of matter to extract information about the internal structure of Earth complementary to seismic studies. Using good directional resolution, ICAL would be able to observe 331 μ− and 146 μ+ core-passing events with 500 kt·yr exposure. With this exposure, we show for the first time that the presence of Earth’s core can be independently confirmed at ICAL with a median ∆χ2 of 7.45 (4.83) assuming normal (inverted) mass ordering by ruling out the simple two-layered mantle-crust profile in theory while generating the prospective data with the PREM profile. We observe that in the absence of charge identification capability of ICAL, this sensitivity deteriorates significantly to 3.76 (1.59) for normal (inverted) mass ordering.

Abstract
Aims/hypothesis
Type 2 diabetes mellitus can manifest over a broad clinical range, although there is no clear consensus on the categorisation of disease complexity. We assessed the effects of canagliflozin, compared with placebo, on cardiovascular and kidney outcomes in the CANagliflozin cardioVascular Assessment Study (CANVAS) Program over a range of type 2 diabetes mellitus complexity, defined separately by baseline intensity of treatment, duration of diabetes and glycaemic control.

Methods
We performed a post hoc analysis of the effects of canagliflozin on major adverse cardiovascular events (MACE) according to baseline glucose-lowering treatments (0 or 1, 2 or 3+ non-insulin glucose-lowering treatments, or insulin-based treatment), duration of diabetes (<10, 10 to 16, >16 years) and HbA1c (≤53.0 mmol/mol [<7.0%], >53.0 to 58.5 mmol/mol [>7.0% to 7.5%], >58.5 to 63.9 mmol/mol [>7.5 to 8.0%], >63.9 to 69.4 mmol/mol [8.0% to 8.5%], >69.4 to 74.9 mmol/mol [>8.5 to 9.0%] or >74.9 mmol/mol [>9.0%]). We analysed additional secondary endpoints for cardiovascular and kidney outcomes, including a combined kidney outcome of sustained 40% decline in eGFR, end-stage kidney disease or death due to kidney disease. We used Cox regression analyses and compared the constancy of HRs across subgroups by fitting an interaction term (p value for significance <0.05).

Results
At study initiation, 5095 (50%) CANVAS Program participants were treated with insulin, 2100 (21%) had an HbA1c > 74.9 mmol/mol (9.0%) and the median duration of diabetes was 12.6 years (interquartile interval 8.0–18 years). Canagliflozin reduced MACE (HR 0.86 [95% CI 0.75, 0.97]) with no evidence that the benefit differed between subgroups defined by the number of glucose-lowering treatments, the duration of diabetes or baseline HbA1c (all p-heterogeneity >0.17). Canagliflozin reduced MACE in participants receiving insulin with no evidence that the benefit differed from other participants in the trial (HR 0.85 [95% CI 0.72, 1.00]). Similar results were observed for other cardiovascular outcomes and for the combined kidney outcome (HR for combined kidney outcome 0.60 [95% CI 0.47, 0.77]), with all p-heterogeneity >0.37.

Conclusions/interpretation
In people with type 2 diabetes mellitus at high cardiovascular risk, there was no evidence that cardiovascular and renal protection with canagliflozin differed across subgroups defined by baseline treatment intensity, duration of diabetes or HbA1c.

Acromioclavicular joint reconstruction implants have differing ability to restore horizontal and vertical plane stability
Authors: Alkoheji Mohamed , El-Daou Hadi , Lee Jillian , Carlos Adrian , Di Mascio Livio , Amis Andrew A. 
Published: August 2021

Abstract
Purpose
Persistent acromioclavicular joint (ACJ) instability following high grade injuries causes significant symptoms. The importance of horizontal plane stability is increasingly recognised. There is little evidence of the ability of current implant methods to restore native ACJ stability in the vertical and horizontal planes. The purpose of this work was to measure the ability of three implant reconstructions to restore native ACJ stability.

Methods
Three groups of nine fresh-frozen shoulders each were mounted into a robotic testing system. The scapula was stationary and the robot displaced the clavicle to measure native anterior, posterior, superior and inferior (A, P, S, I) stability at 50 N force. The ACJ capsule, conoid and trapezoid ligaments were transected and the ACJ was reconstructed using one of three commercially available systems. Two systems (tape loop + screw and tape loop + button) wrapped a tape around the clavicle and coracoid, the third system (sutures + buttons) passed directly through tunnels in the clavicle and coracoid. The stabilities were remeasured. The data for A, P, S, I stability and ranges of A–P and S–I stability were analyzed by ANOVA and repeated-measures Student t tests with Bonferroni correction, to contrast each reconstruction stability versus the native ACJ data for that set of nine specimens, and examined contrasts among the reconstructions.

Results
All three reconstructions restored the range of A–P stability to that of the native ACJ. However, the coracoid loop devices shifted the clavicle anteriorly. For S–I stability, only the sutures + buttons reconstruction did not differ significantly from native ligament restraint.

Conclusions
Only the sutures + buttons reconstruction, that passed directly through tunnels in the clavicle and coracoid, restored all stability measures (A, P, S, I) to the native values, while the tape implants wrapped around the bones anteriorised the clavicle. These findings show differing abilities among reconstructions to restore native stability in horizontal and vertical planes. (300 words)

Published: August 2021

AbstractThe topological entanglement entropy is used to measure long-range quantum correlations in the ground space of topological phases. Here we obtain closed form expressions for the topological entropy of (2+1)- and (3+1)-dimensional loop gas models, both in the bulk and at their boundaries, in terms of the data of their input fusion categories and algebra objects. Central to the formulation of our results are generalized $${\mathcal {S}}$$
S
-matrices. We conjecture a general property of these $${\mathcal {S}}$$
S
-matrices, with proofs provided in many special cases. This includes constructive proofs for categories up to rank 5.
