A series of Bi 2 Sr 2- x Ni x CaCu 2 O 8+ δ (x = 0.00, 0.10, 0.20 and 0.30) ceramics samples were synthesized by Pechini sol-gel method. In this work, the microstructure and structure stability of Ni-doped Bi2212 system were investigated particularly by X-ray diffraction, electron microscopy and high-pressure Raman spectroscopy. It is confirmed that the main phase of all samples is the typical Bi2212 tetragonal phase with space group I 4/ mmm. As Ni-doping amount x ≤ 0.20, the number of Ni atoms entering the Bi2212 lattice increases gradually with increasing x. These Ni atoms preferentially occupy Sr-sites, resulting in a gradual increase in the a and c axis lengths of Bi2212 structure. The formation of containing-Ni Bi2212 lattice is mainly derived from the insertion of sufficient Ni–O two-dimensional (2D) monomers. Contrarily, when x > 0.20, these Ni–O 2D monomers will preferentially form the NiO particle and the chance of Ni atoms entering the Bi2212 lattice is reduced, which leads to a shrinkage of Bi2212 lattice parameters. Besides, under high-pressure (0–20 GPa) condition, Raman spectrum analysis shows that the O Sr peak significantly shifts to the higher wavenumber and Bi2212 phase could still maintain the tetragonal structure, suggesting that it has a relatively high structure stability.

The third-order resonance slow extraction scheme is adopted to achieve high efficiency and continuous uniform extraction of the beam for irradiation experiments. Several innovative accelerator technologies such as titanium alloy lined thin-wall vacuum chamber and fast ramping rate full energy storage power supply are also adopted. In this paper, the general design and simulation results of the accelerator complex are presented, and the new technology and progress of the PREF project are briefly introduced.

Osimertinib is a potent, third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI). The multi-arm phase Ib TATTON study (NCT02143466) was designed to assess the safety and tolerability of osimertinib in combination with other targeted therapies: selumetinib (MEK1/2 inhibitor), savolitinib (MET-TKI), or durvalumab [anti-programmed cell death ligand 1 (anti-PD-L1) monoclonal antibody]. Patients with advanced EGFR -mutant non-small-cell lung cancer and disease progression on a prior EGFR-TKI were enrolled and allocated to dose-escalating cohorts combining osimertinib 80 mg orally (p.o.) once a day with selumetinib (25–75 mg p.o. twice a day; continuous or intermittent), savolitinib (600–800 mg p.o. once a day), or durvalumab (3–10 mg/kg intravenous every 2 weeks). At data cut-off (28 February 2018), 77 patients were enrolled and received osimertinib plus selumetinib (n = 36), savolitinib (n = 18), or durvalumab (n = 23). Most common adverse events (any grade), occurring in ≥20% of patients across dose groups, were: selumetinib arm—diarrhea (75%), rash (58%), nausea (47%); savolitinib arm—nausea (67%), rash (56%), vomiting (50%); durvalumab arm—rash (48%), vomiting (43%), diarrhea (39%). Dose-limiting toxicities were reported in the selumetinib 25 mg (n = 1), 50 mg (n = 1), and 75 mg (n = 4) continuous-dose groups, savolitinib 600 mg (n = 1) and 800 mg dose groups (n = 2), and durvalumab 10 mg/kg (n = 1) dose group. The objective response rate was 42% (95% confidence interval 26% to 59%), 44% (22% to 69%), and 43% (23% to 66%) in the selumetinib, savolitinib, and durvalumab arms, respectively. Our results demonstrate the feasibility of combining osimertinib 80 mg with selumetinib or savolitinib at identified tolerable, active doses. A combination of osimertinib with durvalumab was not feasible due to increased reporting of interstitial lung disease. Osimertinib-based combination therapies represent a compelling approach now being further investigated. NCT02143466. • Patients with advanced EGFR -mutant NSCLC received osimertinib 80 mg combined with selumetinib, savolitinib or durvalumab. • Feasible dosing strategies were identified for osimertinib plus selumetinib or savolitinib. • Osimertinib plus durvalumab was not feasible due to increased reporting of interstitial lung disease. • Responses were seen in all treatment arms, warranting further analysis of the feasible combinations identified. • Osimertinib-based combinations represent a compelling approach now being investigated broadly to further improve outcomes.

Abstract The Isochronous Mass Spectrometry (IMS) based on storage rings is a powerful technique for mass measurement of short-lived exotic nuclei. The transition energy γ t of the storage ring is a vital parameter of the IMS technique. It is difficult to measure the γ t and its relation to momentum spread or circulating length, especially to monitor the variation of γ t during experiments. An experimental investigation on the γ t has been performed for the IMS experiment at the Cooler Storage Ring of the Heavy Ion Research Facility in Lanzhou (HIRFL-CSRe). With the velocity measured by two time-of-flight (TOF) detectors, the γ t as a function of orbital length can be determined. The influences of higher order magnetic field components on the γ t function were inferred for isochronous correction. This paper introduces and investigates the influence of dipole magnetic fields, quadrupole magnetic fields and sextupole magnetic fields on the γ t function. With the quadrupole magnets and sextupole magnets corrections, a mass resolution of 171332 (FWHM) and σ (T) ∕ T = 1. 34 × 1 0 − 6 were reached, which shall be compared with 31319 (FWHM) and σ (T) ∕ T = 7. 35 × 1 0 − 6 obtained without correction.

The Spectrometer Ring (SRing) is an essential part of the High Intensity heavy-ion Accelerator Facility project (HIAF) in China. It is designed as a multi-functional experimental storage ring, which will be able to operate in three ion optical operation modes. The SRing will be used as a time-of-flight mass spectrometer for short-lived, especially neutron-rich nuclei. It will also be used to collect and cool Rare Isotope Beams (RIBs) or highly-charged stable ion beams for nuclear and atomic physics experiments. The design magnetic rigidity is in the range 1.5 to 15 Tm. The beam cooling system consists of stochastic cooling and electron cooling devices. With a help of an electron cooler, stored ions will be decelerated to a minimum energy of 30 MeV/u by RF cavities. The extraction system of the SRing will allow cooled ion beams to be extracted to an external target for further ion manipulations or reaction experiments. The general ion optics design and technical requirements of SRing subsystems are presented and discussed in this paper. [ABSTRACT FROM AUTHOR]

To simulate collective instabilities during the complicated beam manipulation in the BRing (Booster Ring) of HIAF (High Intensity heavy-ion Accelerator Facility) or other high intensity accelerators, a code, named CISP (Simulation Platform for Collective Instabilities), is designed and constructed in China’s IMP (Institute of Modern Physics). The CISP is a scalable multi-macroparticle simulation platform that can perform longitudinal and transverse tracking when chromaticity, space charge effect, nonlinear magnets and wakes are included. And due to its well object-oriented design, the CISP is also a basic platform used to develop many other applications (like feedback). Several simulations, completed by the CISP in this paper, agree with analytical results very well, which shows that the CISP is fully functional now and it is a powerful platform for the further collective instability research in the BRing or other accelerators. In the future, the CISP can also be extended easily into a physics control system for HIAF or other facilities. [ABSTRACT FROM AUTHOR]

Abstract: The translocation of different inorganic phosphorus (Pi) forms in a low-P soil (Langfang experimental station, Hebei province, China) over time was investigated using P fractionation extraction and a 32P tracer technique. The L-value and P availability of the soil was assessed using 5 different maize genotype (Zea mays L.) cultivars. The results showed that the different Pi fractions in the soil increased in the order of H2SO4-extractable P (Ca10–P) > Na3C6H5O7–Na2S2O4-extractable P (O–P) > NH4Ac-extractable P (Ca8–P) > NaHCO3-extractable P (Ca2–P), NH4F-extractable P (Al–P), NaOH–Na2CO3-extractable P (Fe–P), and the content of plant-unavailable P (Ca10–P + O–P) was high, up to 79.1%，which might be an important reason for P deficiency in this low-P soil. The 32P tracer results showed that after the addition of 32P-Pi to the soil with no P fertilizer applied for 25 d, 29.0% of 32P was quickly transformed into Ca2–P (rapidly available P), and 66.1% of 32P was transformed into Al–P, Fe–P and Ca8–P (slowly available P). Only 5.0% of 32P was transformed into O–P and Ca10–P (plant-unavailable P). Moreover, in the soil with P fertilizer applied, 32P transformation into Ca2–P increased, and the transformation into Ca8–P + Fe–P + AL–P and O–P, Ca10–P significantly decreased compared to the soil with no P fertilizer applied (p < 0.05). This result suggested a higher rate for water-soluble P transformation to slowly available and plant-unavailable P in P deficient soil than in soil with sufficient P. The results of maize L-value determination showed that different genotype maize cultivars had different soil P-use efficiency and low-P tolerance mechanisms. Low-P tolerant cultivar DSY-32 regulated soil P-use efficiency and plant P content according to exogenous P fertilizer application. However, another low-P tolerant cultivar, DSY-2, used soil P more efficiently, regardless of the application of exogenous P. [Copyright &y& Elsevier]

Abstract: Single-layered precursors comprising In and Cu11(In,Ga)9 were fabricated by one-step sputtering of a Cu–In–Ga ternary target, subsequently covered by an evaporated Se layer as the source of post-selenization, involving low-temperature (100°C) homogenization and high-temperature (⩾450°C) chalcogenization treatments. Initially it appears that the post-selenization process is inappropriate to fabricate device-quality CIGS absorber layers because the composite precursor is converted into (In,Ga)2Se3 and Cu3Se2 with segregated phases and roughened topography. However, adequately controlling the processing steps leads to a fully microstructure-homogenized precursor, offering a new route and chemical reaction process to fabricate Cu(In,Ga)Se (CIGS) absorber layer with sounding crystallinity.

Abstract: Wrinkling is the predominant failure and may be eliminated by appropriate control of blank holding force (BHF) in stamping of sheet metal parts. A new scheme for BHF was introduced in order to apply more realistic BHF in simulation. Different blankholder gaps (BHG) were used to simulate the blank holding process. The optimum BHG was determined through a systematic approach. It is found that the wrinkling in the flange region of the blank increases with the augmentation of the BHG. And the BHF varies owing to the variety of the stiffness of the flange sheet metal. Different shell element types based discrete Kirchhoff theory and Mindlin theory were used to simulate the deep drawing process with the optimum BHG. A comparison of the thickness and flange contour between the simulation results and experiment shows that the 4-node thin shell element based discrete Kirchhoff theory is better in the simulation of the sheet metal forming process and also has merit in not requiring much time.

The optical extinction coefficients of post-flame soot have been measured in the wavelength range 2.8 to 4.1 μm. A laminar diffusion burner was combined with an infrared spectrograph and gravimetric measurements to determine the mass specific extinction coefficient, σs, and the dimensionless extinction coefficient, Ke. Using ethene gas as the fuel, the burner was operated at four global equivalence ratios (φ = 0.8, 1.0, 2.0, and 3.0) to examine the effect of the fuel-air ratio on the extinction coefficient. The extinction coefficient was found to decrease with increasing values of the global equivalence ratio for φ = 1.0, 2.0, and 3.0. The results for φ = 0.8 and φ = 1.0 were in agreement to within the uncertainty of the measurements. Measurements were obtained using propane gas as the fuel (φ = 1.0) and resulted in extinction coefficients equivalent to those of ethene. Transmission electron microscopy (TEM) images revealed differences in the morphology of the particles, consistent with the quantitative differences observed in the extinction data. The data indicate that the equivalence ratio has a strong effect on the optical properties of post-flame soot agglomerates. [Copyright &y& Elsevier]

In this paper, the authors explore a dynamic super-speed forming method driven by laser shock waves. The initial exploration of laser shock forming (LSF) is done through bulge testing with specimens of 430 sheet metal, using a neodymium–glass laser of pulse energy 10–30 J and duration 20 ns (FWHM). The investigation revealed that the plastic deformation during the LSF is characterized as ultra-high strain rate, and it is indicated that the plastic deformation increases non-linearly with the increase of the energy density of the laser. By investigating the hardness and residual stress of the surfaces, it is conclude that LSF is a combination technique of laser shock strengthening and metal forming for introducing strain hardening and a compressive residual stress on the surface of the workpiece. This technique can achieve forming with or without a mold. [Copyright &y& Elsevier]

The identification of Casuarina grown in Taiwan is difficult probably because of introgressive hybridization. In this study, 456 individual samples were evaluated for RAPD variation in order to assess the genetic diversity and to identify hybridization in Casuarina in Taiwan. Eleven primers were used and 81 polymorphic bands were scored. The average Nei's gene diversity of Casuarina grown in Taiwan (0.198) was significantly higher (P < 0.001) than those of native provenances of C. equisetifolia (0.140), C. cunninghamiana (0.148), and C. glauca (0.106) based on Duncan's new multiple range test. The results of cluster analysis and principal coordinates analysis support the hypothesis of hybridization of Casuarina in Taiwan. A dendrogram based on RAPD data showed that most sampling sites formed a subgroup that linked with native provenances of C. equisetifolia, indicating that most plants in Taiwan are close to but not typical C. equisetifolia. Two sampling sites in Taiwan linked with native provenances of C. glauca, indicating that some plants were close to this species. The two- and three-dimensional diagrams derived from principal coordinates analyses indicated that the plants were located among C. equisetifolia, C. cunninghamiana, and C. glauca and generally closer to the first species. These results strongly indicate that most plants of Casuarina currently grown in Taiwan are the result of introgressive hybridization involving C. equisetifolia, C. glauca, and perhaps C. cunninghamiana. The results also imply that most plants are derived from the backcrossing to C. equisetifolia. [ABSTRACT FROM AUTHOR]

The prototype will be tested for the commercial application of on-site power generation. The long run, reliability and economic feasibility of the prototype will be analyzed for commercial power generation. [Copyright &y& Elsevier]

Human epidermal growth factor receptor 3 (HER3) is broadly expressed in non-small-cell lung cancer (NSCLC) and is the target of patritumab deruxtecan (HER3-DXd), an antibody–drug conjugate consisting of a HER3 antibody attached to a topoisomerase I inhibitor payload via a tetrapeptide-based cleavable linker. U31402-A-U102 is an ongoing phase I study of HER3-DXd in patients with advanced NSCLC. Patients with epidermal growth factor receptor (EGFR)-mutated NSCLC that progressed after EGFR tyrosine kinase inhibitor (TKI) and platinum-based chemotherapy (PBC) who received HER3-DXd 5.6 mg/kg intravenously once every 3 weeks had a confirmed objective response rate (cORR) of 39%. We present median overall survival (OS) with extended follow-up in a larger population of patients with EGFR -mutated NSCLC and an exploratory analysis in those with acquired genomic alterations potentially associated with resistance to HER3-DXd. Safety was assessed in patients with EGFR -mutated NSCLC previously treated with EGFR TKI who received HER3-DXd 5.6 mg/kg; efficacy was assessed in those who also had prior PBC. In the safety population (N = 102), median treatment duration was 5.5 (range 0.7-27.5) months. Grade ≥3 adverse events occurred in 76.5% of patients; the overall safety profile was consistent with previous reports. In 78/102 patients who had prior third-generation EGFR TKI and PBC, cORR by blinded independent central review (as per RECIST v1.1) was 41.0% [95% confidence interval (CI) 30.0% to 52.7%], median progression-free survival was 6.4 (95% CI 4.4-10.8) months, and median OS was 16.2 (95% CI 11.2-21.9) months. Patients had diverse mechanisms of EGFR TKI resistance at baseline. At tumor progression, acquired mutations in ERBB3 and TOP1 that might confer resistance to HER3-DXd were identified. In patients with EGFR -mutated NSCLC after EGFR TKI and PBC, HER3-DXd treatment was associated with a clinically meaningful OS. The tumor biomarker characterization comprised the first description of potential mechanisms of resistance to HER3-DXd therapy. • The phase I U31402-A-U102 study evaluated HER3-DXd in heavily pretreated patients with EGFR -mutated NSCLC. • Ninety-seven patients previously treated with EGFR TKI and PBC received HER3-DXd 5.6 mg/kg intravenously every 3 weeks. • Responses were seen across the range of HER3 expression and across diverse mechanisms of resistance to EGFR TKI therapy. • Acquired mutations in ERBB3 were characterized. • OS was 15.8 months (95% CI 10.8-21.5 months).

In this paper the closed orbit correction of the Heavy Ion Medical Machine (HIMM) synchrotron is described. Results of simulations and measurements are presented. Consistently with simulations, it is possible to correct the maximum closed orbit distortion of the HIMM synchrotron down to 2.4mm in the horizontal direction and 0.7mm in the vertical one. The errors of dipole magnets, especially the longitudinal alignment errors (Δ s), have large impact on the horizontal correction results. A Singular Value Decomposition (SVD) algorithm is adopted for computing the correction. The residual orbits and the effects of reducing the number of singular values are analytically expressed and simulated. In addition, the influences of BPM reading errors as well as corrector setting errors are analyzed. For further optimization, the method to estimate the dipole errors is studied. In the commissioning, the maximum closed orbits at BPMs can also be well corrected to within 1mm through SVD algorithm. [ABSTRACT FROM AUTHOR]

• The deformation transition behavior in tube free bending is analytically solved. • A new correction method employing a modified U-R relationship is proposed. • The correction method is validated to improve the forming accuracy of bent tubes. The deformation transition has a significant impact on the forming accuracy in tube free bending. In this paper, the formation mechanism of deformation transition in free bending is analytically revealed. Considering the bending angle and the length of forming area in the transition segment, a modified relationship between the bending die deviation U and the bending radius R is proposed by introducing a new correction factor k. The developed correction method is carefully verified by free bending experiments and simulations using AA5052 tubes, and further, the influence mechanism of the deformation transition in free bending is clarified. This study provides new insights into the understanding of deformation transition in free bending, providing an effective way to design more accurate and robust bending processes for improving product quality.

Abstract In this paper, commercial Ce-W cathode was selected as research object. The cathode working environment was simulated by heating in an ultra-high vacuum (UHV) chamber. Scanning electron microscopy (SEM), Nano-scanning Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) were used to study the surface morphology and chemical states from 900 °C to 1200 °C. The results showed that W6+ disappeared and the surface of the cathode was composed entirely of W0 in heating process. The content of Ce4+ gradually decreased by heating and cerium oxide had a tendency to reduce. The adsorbed oxygen disappeared and the lattice oxygen was present in CeO 2 and Ce 2 O 3. Moreover, when raising heating temperature, the rare earth oxide diffused from the aggregation areas to the tungsten matrix surface to form an active layer. The surface cerium oxide was highest at 1100 °C. Then the thickness of active layer was about 6 nm. At 1200 °C, the evaporation rate of cerium oxide on the surface was greater than the rate of migration from the body to the surface. And the loss of the surface active layer was severe at 1200 °C.

Abstract The dynamic vacuum effect induced by the charge exchange beam loss will seriously limit the ion intensity and beam lifetime in the Booster Ring (BRing) of the High-Intensity Heavy Ion Accelerator Facility (HIAF). A dedicated collimation system has been designed to decrease the ion-induced gas desorption to suppress the dynamic vacuum effect. In order to reach 100% collimation efficiency, the optics lattice of BRing has been changed from original FODO to DBA structure. The distance between dipole and quadrupole in each lattice cell of BRing was optimized to maintain the high collimation efficiency. The hardware structure of the collimator was designed based on the simulation result and mechanical instrument control principle in the UHV vacuum system. The vacuum chamber and pump installment with collimators has been designed. A prototype collimator with vacuum chamber has been installed on the beamline to measure the gas desorption with beam and verify the availability and reliability of mechanical design. This prototype collimator has passed factory field tests and used to measure the gas desorption rate with the beam 112Sn 26 + at the energy 150 MeV/u successfully. [ABSTRACT FROM AUTHOR]
