Large language models (LLMs) have demonstrated remarkable proficiency in mainstream academic disciplines such as mathematics, physics, and computer science. However, human knowledge encompasses over 200 specialized disciplines, far exceeding the scope of existing benchmarks. The capabilities LLMs many these fields-particularly light industry, agriculture, service-oriented disciplines-remain inadequately evaluated. To address this gap, we present SuperGPQA, a comprehensive benchmark that...
Efficient fluorescence/phosphorescence hybrid white organic light-emitting diodes (OLEDs) with single doped co-host structure have been fabricated. Device using 9-Naphthyl-10 -(4-triphenylamine)anthrancene as the fluorescent dopant and Ir(ppy)3 Ir(2-phq)3 green orange phosphorescent dopants show luminous efficiency of 12.4% (17.6 lm/W, 27.5 cd/A) at 1000 cd/m2. Most important to note that efficiency-brightness roll-off device was very mild. With brightness rising up 5000 10 000 cd/m2, could...
Abstract A new carbazole–fluorenyl hybrid compound, 3,3′(2,7‐di(naphthaline‐2‐yl)‐9H‐fluorene‐9,9‐diyl)bis(9‐phenyl‐9H‐carbazole) (NFBC) was synthesized and characterized. The compound exhibits blue‐violet emission both in solution film, with peaks centered at 404 420 nm. In addition to the application as a blue emitter, NFBC is demonstrated be good host for phosphorescent dopants. By doping Ir(2‐phq) 3 NFBC, highly efficient orange organic light‐emitting diode (OLED) maximum efficiency of...
Nonlinear time-varying contact state and uneven allowance distribution are factors to prevent traditional robotic belt grinding from high-precision machining of aero-blade. For this case, a novel region-based force control (RFC) strategy with consideration regional division is proposed achieve grinding. Ideal normal at cutter-contact (CC) points calculated based on principle curvature the corresponding CC points. Then, similar ideal divided into one region iterated threshold. Furthermore, an...
The efficient compression of kernel matrices, for instance the off-diagonal blocks discretized integral equations, is a crucial step in many algorithms. In this paper, we study application Skeletonized Interpolation to construct such factorizations. particular, four different strategies selecting initial candidate pivots algorithm: Chebyshev grids, points on sphere, maximally-dispersed and random vertices. Among them, first two introduce new interpolation (exo-vertices) while last are...
Abstract In this study, colloidal ternary Zn x Cd 1-x S white light quantum dots (WQDs) were prepared, which have the characteristics of broad emission window. We used epoxy, styrene ethylene butylene block copolymer (SEBS), and silicone as encapsulate materials to pack device.

White light quantum dots (WQDs) such as CdSe and ZnxCd1-xS are considered source candidates in solid-state lighting (SSL) due to their unique optical properties. However, the low fluorescence yield (QY, < 60 %), luminous efficacy (~11.9 lm/W), poor stability (~100 hr) limits commercial application. In order solve above problems, a high QY of ZnxCd<sub>1-x</sub>S WQDs (x=0.2, 0.5 0.8, named Zn0.2, Zn0.5 Zn0.8, respectively) was prepared by using unsaturated fatty acid-oleic acid (OA)...
Laser processing plays a key role in treating lot of materials. The mechanism laser stealth dicing (SD) is based on irradiation beam which focused inside the brittle material. scans along predetermined path, so that characteristics interior material can be changed, stress layer therefore formed. Finally, an external force applied to separate Since only limited region wafer processed by irradiation, damages and debris contaminants avoided during SD process. has advantages high speed for...
Laser drilling has been more and widely used in laser machining process. Therefore, optimizing the quality of becomes extremely important. We know that can be achieved by using high power density a laser. As light waves with different waveforms represent energy distributions time domain, we believe should related to waveform. At present, processing usually hasthe waveform Gaussian or Lorentzian distribution. In this study, numerically simulated punching pulsed distribution top-flat (we...
