Pediatric Feeding Disorder in Early Intervention: Expanding Access, Improving Outcomes, and Prioritizing Responsive Feeding
Authors: Cohen Stephanie C. , Dilfer Karen 
Published: June 2022

Purpose:
Pediatric feeding disorder (PFD), like many childhood medical conditions, is likely to negatively impact a child's growth and development, daily learning opportunities, and family functioning. Parents who have children with a diagnosis of PFD may not yet know the most effective way to feed their children and often experience negative emotions surrounding mealtimes. These families may receive therapy services through early intervention (EI) programs. In many states, there are barriers that limit access to programs and provision of high-quality care for this population. These barriers include the lack of an approved single feeding-related diagnosis that renders a child automatically eligible, lack of approved stand-alone feeding-specific testing tools with which to determine eligibility, lack of educational and clinical experience requirements for providers, and considerable variation in service provision.

Method:
This clinical focus article reviews the definition of PFD, the multifaceted needs of families and children in EI, support for use of responsive feeding in treatment of PFD, alignment of responsive feeding strategies with EI principles, and barriers limiting access to consistent, high-quality EI services for children with PFD. Several changes to EI programs are proposed to address these barriers.

Conclusions:
Use of PFD as an automatically qualifying diagnosis for EI programs and use of approved stand-alone feeding-specific assessment tools could establish more consistent and specific eligibility standards for this population, likely expanding early access to support and improving outcomes. EI provider clinical experience and training requirements would likely lead to more consistent and high-quality, evidence-based service provision. Required training should include the use of methods such as routines-based intervention, parent coaching, and anticipatory guidance to support implementation of responsive feeding practices during mealtime routines.

Published: June 2022

AbstractIn this brief, a type of novel fully distributed adaptive protocols is designed for achieving leader‐follower multi‐agents tracking. The design procedure constitutes three steps. First, a local observer is constructed for each agent (including the leader) in virtue of its own inputs and outputs, aiming to estimating of that agent's state. Second, to propagate the estimate of the leader from target followers to all the followers, a distributed adaptive estimator is then proposed, via embedding with time‐varying coupling weights. At last, an elegant controller is designed for each follower based on the estimate of its own state and the estimate of the leader's state. The rigorous convergence analysis is provided. Finally, the simulation results validate the effectiveness of the proposed protocols.
Underwater localization using an optic and acoustic stereo imaging system for autonomous intervention robots
Authors: Park Jisung , Kim Jinwhan 
Published: June 2022

AbstractOptical and acoustic stereo imaging has great potential for the precise and consistent localization of intervention underwater robots; however, it is still being explored due to its sensing limitations and various technical challenges. This study presents a novel localization method by combining an inertial navigation system and an optical and acoustic stereo imaging system. As a strategy for localization correction relative to underwater structures, the robot's pose is estimated based on a single acoustic image using a sonar simulator for mid‐range localization, and a robust visual tracking using a 3‐D wireframe model is employed for high‐precision localization near the target structures. The performance of the proposed technique was demonstrated through experimental validation using real data obtained from a test tank.
Low‐carbon generation expansion planning considering flexibility requirements for hosting wind energy
Authors: Pourmoosavi Mohammad‐Amin , Amraee Turaj 
Published: June 2022

AbstractThe operational flexibility of electric energy systems is one of the essential requirements for integrating a high share of renewable resources. The operational flexibility significantly impacts the mix of new power generation technologies. In this paper, a low‐carbon generation expansion planning (GEP) model is presented to investigate the impacts of flexibility requirements of power systems with a high share of wind energy. An improved clustered unit commitment (CUC) formulation is proposed to capture the flexibility limitation of thermal generating units fully. In this regard, clustered 10‐min ramp up/down limits for operational reserves, flexible‐ramp reserves, and contingency reserves, are introduced. The yearly variations of load and renewable generations preserving the chronological time correlations are included, considering 36 representative days obtained by the clustering approach. Besides, two types of BES devices are considered to investigate the role of BES in the provision of flexibility. The proposed flexible low‐carbon GEP model is formulated as a mixed‐integer programming model, and an optimal expansion plan is obtained using the CPLEX algorithm. By incorporating improved CUC formulation into the low‐carbon GEP model, more profound insight into power systems' flexibility requirement with high wind generation penetration is obtained.

Strategies to prevent infection and improve outcomes in patients with cirrhosis. HAV, hepatitis A virus; HBV, hepatitis B virus; COVID-19, novel coronavirus disease 2019; NSBB, nonselective β-blocker; PPI, proton pump inhibitors.Cirrhosis is a risk factor for infections. Majority of hospital admissions in patients with cirrhosis are due to infections. Sepsis is an immunological response to an infectious process that leads to end-organ dysfunction and death. Preventing infections may avoid the downstream complications, and early diagnosis of infections may improve the outcomes. In this review, we discuss the pathogenesis, diagnosis, and biomarkers of infection; the incremental preventive strategies for infections and sepsi; and the consequent organ failures in cirrhosis. Strategies for primary prevention include reducing gut translocation by selective intestinal decontamination, avoiding unnecessary proton pump inhibitors' use, appropriate use of β-blockers, and vaccinations for viral diseases including novel coronavirus disease 2019. Secondary prevention includes early diagnosis and a timely and judicious use of antibiotics to prevent organ dysfunction. Organ failure support constitutes tertiary intervention in cirrhosis. In conclusion, infections in cirrhosis are potentially preventable with appropriate care strategies to then enable improved outcomes.

Published: June 2022

AbstractThe bifunctional Lewis acidic ionic liquid (LAIL) catalyzed multicomponent arylsulfonation of phenols with aryl triazenes and DABSO was developed. By using LAILs as redox and Lewis acidic catalysts without any additional promoter or ligand through an N2 extrusion/SO2 insertion sequence, various aryl triazenes were transformed into aryl sulfonyl radicals by coupling with DABSO, and these were then coupled with phenoxy radicals to afford the corresponding diaryl sulfones in good yields. The good functional-group tolerance, gram-scale reaction, and avoidance of the use of SO2 gas further demonstrated the practicality of this arylsulfonation reaction.

Published: June 2022

AbstractTwenty-three new quercetin-1,2,3-triazole hybrids were synthesized in good to quantitative yields via Cu(I)-catalyzed azide-alkyne cycloaddition reaction under microwave irradiation. These new hybrids contain a 1,4-disubstituted 1,2,3-triazole ring at the 3-OH position of quercetin whilst the remaining hydroxyl groups were either protected as methyl or benzyl groups or left unprotected. All the quercetin-1,2,3-triazole hybrids I–IV were evaluated against REM-134 canine mammary cancer cell line, which is used as a translational model for human breast cancer. These new analogues exhibit potent antiproliferative activity against this cancer cell line. Furthermore, the results show that some of the new quercetin-1,2,3-triazole hybrids have better activity than quercetin. Our best inhibitors displayed IC50 values in the range of 41–180 nM, and undoubtedly will have an important impact on the treatment of both canine and human breast cancer.

Abstract
Efficient inverted (p–i–n) type CsPbI3 perovskite solar cells (PSCs) have revealed promising applications due to their excellent thermal and photostability. Regulating the nucleation and crystallization of perovskite film is an important route to improving the performance of CsPbI3 PSCs. Herein, we explored cesium acetate (CsAc) as additive to manipulate the crystallization process of CsPbI3 perovskite films. By involving in the intermediate phase DMA1-x

of perovskite, the pseudo-halide acetate (Ac−) can retard the ion exchange reaction between DMA+ and Cs+, leading to a perovskite with dense morphology, low defect density, and a long carrier lifetime. As a result, the optimal CsPbI3 PSCs yielded a high power conversion efficiency of 18.3%. Moreover, the encapsulated devices showed excellent operational stability and the devices retained their initial performance following 500 h of operation at the maximum power point under one-sun illumination in ambient conditions.

Published: June 2022

Abstract
A multi-wavelength erbium-doped fiber laser using tungsten disulfide (WS2) as a nonlinear saturable absorber is proposed. The laser structure consists of a Lyot filter and a WS2 film in a ring cavity. The WS2 film attached to the end of the fiber jumper can suppress the mode competition phenomenon caused by erbium-doped fiber due to its good nonlinear optical properties. In addition, it can suppress mode contention and stabilize multi-wavelength output. The number of wavelengths can be tuned by adjusting the length of the polarization-maintaining fiber (PMF). In the Lyot filter, the PMF of 4, 8 and 12 m excite 5, 9 and 13 wavelengths with 1.38, 0.7 and 0.42 nm intervals, respectively. The experimental results show that in the range of 1528–1536 nm, the side-mode suppression ratio is 42 dB. After 60 min of continuous excitation, the output wavelength of the structure remains stabilization. It can be used as a light source in distributed sensing and wavelength division multiplexing systems.
Ultra-intense laser-accelerated ion beams for high-gain inertial fusion: the effect of the ion mass on the beam properties
Authors: Badziak Jan , Domański Jarosław 
Published: June 2022

Abstract
This paper presents the results of detailed numerical studies of the properties of ion beams generated by a laser from targets with various atomic numbers under conditions relevant for ion fast ignition (IFI) of inertial fusion. The interaction of a 200 kJ 1 ps infrared (1.05 μm) laser with Li, C, Al, Ti, Cu and CH2 flat targets with the same areal mass density was numerically simulated using an advanced 2D3V particle-in-cell code. For each target, a set of ion beam characteristics important for IFI was determined. A detailed quantitative comparison of the IFI-relevant parameters of Li, C, Al, Ti and Cu ion beams and the proton beam (from the CH2 target) was made. The laser-accelerated Cu ion beam was found to achieve significantly higher values of beam intensity, fluence and ‘useful’ energy (for IFI), having a smaller angular divergence and a narrower energy spectrum than the beam of light ions or protons. Thus, it is shown for the first time that laser-accelerated heavy ion beams can achieve IFI-relevant parameters higher than light ion or proton beams and can potentially meet IFI requirements.
Analysis of the causes of undesirable curvature of the workpiece during longitudinal rolling using numerical simulation
Authors: Benešová S , Burdová Karolína , Hajšman J 
Published: June 2022

Abstract
Undesirable additional deformation was observed during the experimental cold rolling of steel. A simulation was performed in Deform software to clarify the causes. The influence of the unequal coefficient of friction, geometric inaccuracies of the rolls and the conveyor, and the situation when the rolls did not have the same diameter or rotated at different speeds were investigated. Simulations with different roll speeds corresponded best to reality. The simulation of the undesired curvature of the workpiece at different speeds of rotation of the rolls and 30% reduction was subsequently performed as an elastoplastic problem in order to determine the amount of springback and residual stress. Furthermore, the press straightening of the workpiece was simulated. Inhomogeneous and accidental deformation and residual stresses must be taken into account, especially when researching the effect of cold rolling on the mechanical properties and structure of the material.

Authors: Coufal V , Křesťan J , Vnouček M 
Published: June 2022

Abstract
ARMOX low-alloy high-strength steel sheet is used, among other things, as a basic homogeneous ballistic protection in plate carriers and vehicle bodies. The hardest armour plates of the ARMOX series include ARMOX Advance, which, even with a smaller thickness, provides the same ballistic protection as the stronger ARMOX 500 or ARMOX 600 sheets. The manufacturer of ARMOX armour plates declares for the ARMOX Advance with a thickness of 5 mm the resistance to small arms fire with 7.62x51 and 5.56x45 rounds according to NATO AEP-55 STANAG 4569 Annex A level 1 and for the thickness of 7 mm the ballistic resistance to small arms fire with 7.62x39 API BZ rounds according to NATO AEP-55 STANAG 4569 Annex A level 2. Due to the manufactured thicknesses, ballistic resistance is not specified for levels 3 to 6 in accordance with NATO AEP-55 STANAG 4569 Annex A. For levels 1 to 3, STANAG 4569 does not require a test against flying fragments from 155 mm artillery shells, but it is an optional component at the discretion of the national authority. In order to be able to use this type of sheet for this purpose, empirical equations were used to determine whether the conditions set out in STANAG 4569 Annex A Level 1 and Level 2 are met over the full range of ballistic resistance required. From the results obtained it was found that the ballistic resistance of ARMOX Advance armour plate against flying artillery shell fragments is not met and therefore it cannot be used alone as a basic homogeneous ballistic protection in vehicle bodies and protective sheet carriers to provide protection of persons in areas where artillery fire is expected.

Published: June 2022

Abstract
Austenitic stainless steel 08Ch18N10T stabilised with titanium is used for parts of VVER nuclear power reactors. The final mechanical properties are strongly affected by the previous processing history. This is mainly due to the deformation hardening that is incorporated into the material during the production of semi-finished products. The experimental program was performed on 08Ch18N10T steel bars with a diameter of 30 mm. Incremental rolling was performed on bars that remained in the delivered condition and on bars subjected to solution annealing at 1020 °C for 60 minutes before rolling. The rolled bars were stabilised annealed at different temperatures. Then a metallographic evaluation and a tensile test at RT and 350 °C were performed. The results show that the rolling speed significantly affects the mechanical properties after stabilisation annealing. By reducing the rolling speed, it was possible in some cases to increase the yield strength up to 349 MPa. The stabilisation annealing temperature of 720 ° C with a holding time of 10 hours was evaluated as the most advantageous. In the case of higher stabilisation annealing temperatures, the lowest rolling speed, i.e. 25 rpm, had to be performed to achieve higher hot yield strength values exceeding 177 MPa.

Published: June 2022

Abstract
This paper is focused on the possibility of the implementing various additive manufacturing technologies into the investment casting process. The most frequently used AM technologies were employed to print fusible models of valves for musical instruments. This was done to accelerate the production process of new products in the foundry. The output of the work should determine the optimal AM technology according to the quality of surface and shape for creating a fusible model and suitable materials should also be recommended. Furthermore, the financial aspects of the variants were evaluated. For this evaluation, the analyses of the ash content, visual inspection, surface roughness and topography of the printed models were done. After these analyses, the models were formed, moulds were fired and the tin alloy was cast. Castings were subjected to the same analyses as for the models. X-ray inspection was done and finally the defects of the castings were evaluated.
Prediction of defects of ductile iron casting by numerical simulation

Published: June 2022

Abstract
Conditions favourable for the development of internal defects in cast pieces may occur in the course of ductile iron casting. The presence of such defects may be fatal for the castings and, together with other factors, result in their disposal. Therefore, any defects should be revealed as early as in the casting design phase if possible. This can be achieved through numerical simulations, a tool commonly used today to predict defects. This paper describes the procedure of numerical modelling of ductile iron casting and solidification of castings intended for the power industry. The purpose of our numerical simulations was to predict filling, solidification and stress states in order to verify whether the proposed production technology is adequate. The numerical simulations revealed some minor deficiencies in the production technology which might lead to defects should an unexpected change in the process conditions occur. In particular, these defects concerned the inlet system, risers, and susceptibility to cracking. Measures to eliminate the risks associated with development of the above-mentioned defects were proposed based on the simulations, which will be integrated in the production technology.

Published: June 2022

Abstract
To reduce the cost of manufacturing tools, which are commonly made from powder steels, high-alloy tool steel in the form of an ingot was cast. Conventional casting allows better use of recycled materials and an overall reduction in material production costs. This experimental steel was then processed in a semi-solid state to remove the unsuitable casting structure and to obtain the desired functional properties. In the case of tools, it is primarily a sufficient toughness and abrasion resistance. To determine the wear resistance of the experimental steel, replaceable inserts for machining tests were made. The inserts were prepared by electro-erosive machining. During testing, the geometry of the insert was optimized to achieve good chip evacuation and other cutting properties. Wear was measured using a digital microscope and at the same time, the roughness of the workpiece was measured. For comparison, a powder steel insert of the corresponding chemical composition was also produced, which has the commercial title Böhler K390 Microclean. This steel was heat-treated according to the manufacturer's recommendations. By comparing the results obtained on experimental cast steel and commercially produced powder steel, it was found that cast steel processed by semi-solid technology achieves three times lower cutting-edge wear during machining than powder steel.
Usage of the 3D printed model for the forming during the development of the casting mould

Published: June 2022

Abstract
This paper deals with the usage of the plastic model (created by additive technology), which can be used for the mould production as an internal model for the cavity. This mould is intended for the steel casting technology. The particular plastic model is created by the conventional 3D printer HP Multi Jet Fusion 4200 from the material PA 12 GB. It is polyamide with 40% of glass filling. This material is suitable for this method because of good mechanical properties. The creating of the steel casting mould has some specification which are deeply described in this paper. The comparing of several dimensions between the CAD model, plastic model and the final casted model from steel is performed here. It is obvious that the differences and tolerances are less than 1%. This approach can be used as a replacement of the wood models which are generally used. The benefits of the 3D printed model are higher accuracy of the model, higher complexity of the model and production time which can be less than 3 days (from the CAD model to the plastic model for the casting mould, but depending on complexity and size of the model).
