In low-cost permanent magnet synchronous motor (PMSM) drive systems, the rotor position is usually estimated based on the back-electromotive force. However, such estimation methods have the common drawback of having large errors in low-speed regions. In order to solve that drawback in the startup phase, the I-f startup method is studied as its compatibility with the FOC control structure. The purpose of such a method is to make the motor accelerate and overcome the low-speed threshold.

As a potential target receptor tyrosine kinase, mesenchymal-epithelial transition factor (MET) exhibits high aberrant expression across various tumors. This study aimed to evaluated the safety, tolerability, efficacy and pharmacokinetics (PK) of BPI-9016M, a novel tyrosine kinase inhibitor (TKI) targeting c-MET, in c-MET overexpression or MET exon 14 skipping mutation patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC).

Bladder and urinary tract cancers account for approximately 21,000 new diagnoses and 5,000 deaths annually in the UK. Approximately 90% are transitional cell carcinomas where advanced disease is treated with platinum based chemotherapy and PD-1/PD-L1 directed immunotherapy.

In this work, we theoretically investigate phase transitions, electronic structures and thermodynamic properties of Mg2X (X ¼ Ge, Si and Sn) under high pressures. To reach this goal, the total energy has been calculated by using the full-potential linearized augmented plane wave (FP-LAPW) method with generalized gradient approximation (GGA), local density approximation (LDA) and EngeleVosko approximation (EV-GGA), which are based on the exchange-correlation energy optimization.

We numerically study in this work the magnetic properties induced by the on-site electron-electron interaction in graphene nanoflakes shaped diamond with a variety of sizes. By the mean-field Hubbard approximation, a phase transition in analogy to infinite graphene from non-magnetism to antiferromagnetism is observed.

By using the Molecular Dynamics simulation (MD) method, this study aims to show the influences of cooling rates on the solidifying temperature of the water inside a single-wallcarbon-nanotube (SWCNT) under different ambient pressures. This study generally provides more insight into water behavior in the SWCNT with variations in ambient conditions.

The program developed in this study will be put at the service of every researcher, and the system of the program can be used on any Windows Software compatible computer. While preparing the program, an easy-to-understand and flexible MATLAB environment was used. The thermal analysis data of synthesized N’-(4-chlorobenzoyl)-N,N-di-n-butylthiourea (HL) and its Ni(II) complex have been digitalized by measuring with thermal analyses such as DTA, TG with hardware technical equipment.

In this work the results of the study on a generalization of the XY model with an additional q-fold nematic-like term through Monte Carlo simulations in two dimensions (2D) have been presented. While the conventional 2D XY model has only integer vortexes, the generalized 2D XY model has both integer and non-integer 1/q vortexes, making the phase diagram of the generalized 2D XY model is much richer than that of the conventional 2D XY model.

The location of interface plays a pivotal role in studying on wetting phase transition of Bose-Einstein condensates (BECs) mixture. Beside parameters of system, the position of the interface depends on the applied boundary condition. Using double-parabola approximation (DPA), we consider the dependence of position of interface on parameters in semi-infinite space under Neumann boundary condition.

The exit from socio-technical regimes enjoys increasing scientific interest. While many studies which cover energy or sustainability transitions focus on system contexts, there is still a lack of research focusing on the locations and arenas of negotiation.

The selective reduction of sulfur dioxide with carbon monoxide to elemental sulfur was studied over ACsupported transition-metal oxide catalysts. Catalyst samples were characterized by X-ray powder diffraction in order to relate the phase composition to the activation behavior and catalytic performance. The active phase of catalyst was detected as FeS2, and the formation of FeS2 was greatly dependent on the sulfidation temperature.

A series of dimeric unsymmetrical liquid crystals derived from heterocyclic 1,3-dimethylbarbituric acid exhibiting smectic A and nematic phase are reported. All compounds were prepared by the condensation of 4’-(R-(4- formylphenoxy)butoxy)biphenyl-4-carboxylate with 1,3-dimethylbarbituric acid in ethanol. The mesomorphic properties were investigated by DSC and POM, where the type of phase depends on the length of spacer alkoxy chains and the length of the terminal chain.

This study aimed to develop a photocatalyst that responds to visible light. For the preparation of visible light sensitive photocatalysts, N was doped into TiO2(N-TiO2). To inhibit the recombination of excited electrons and holes, transition metals (M = Pt, Cu, Fe, Cr) were loaded on the N-TiO2. N-TiO2 nanotubes were also synthesized by a hydrothermal treatment of the prepared N-TiO2 in a strong basic environment.

We present the results of a study related to phase transformation of chemically synthesized FePt nanoparticles under high pressure from face-centered cubic into face-centered tetragonal structure. As-synthesized nanoparticles are around 4.5 nm and show superparamagnetic behavior at 300 K. After annealing under 60 bar pressure of hydrogen at 400◦C for 2 h, nanoparticles exhibit strong ferromagnetic behavior with 5391 Oe coercivity.

SQUAMOSA PROMOTER BINDING PROTEIN (SBP)-box genes encode a family of plant-specific transcription factors (TFs) that play important roles in many growth and development processes including phase transition, leaf initiation, shoot and inflorescence branching, fruit development and ripening etc. The SBP-box gene family has been identified and characterized in many species, but has not been well studied in Petunia, an important ornamental genus.
