On Realization of Intelligent Decision-Making in the Real World: A Foundation Decision Model Perspective
Our situated environment is full of uncertainty and highly dynamic, thus
hindering the widespread adoption of machine-led Intelligent Decision-Making
(IDM) in real world scenarios. This means IDM should have the capability of
continuously learning new skills and efficiently generalizing across wider
applications. IDM benefits from any new approaches and theoretical
breakthroughs that exhibit Artificial General Intelligence (AGI) breaking the
barriers between tasks and applications. Recent research has well-examined
neural architecture, Transformer, as a backbone foundation model and its
generalization to various tasks, including computer vision, natural language
processing, and reinforcement learning. We therefore argue that a foundation
decision model (FDM) can be established by formulating various decision-making
tasks as a sequence decoding task using the Transformer architecture; this
would be a promising solution to advance the applications of IDM in more
complex real world tasks. In this paper, we elaborate on how a foundation
decision model improves the efficiency and generalization of IDM. We also
discuss potential applications of a FDM in multi-agent game AI, production
scheduling, and robotics tasks. Finally, through a case study, we demonstrate
our realization of the FDM, DigitalBrain (DB1) with 1.2 billion parameters,
which achieves human-level performance over 453 tasks, including text
generation, images caption, video games playing, robotic control, and traveling
salesman problems. As a foundation decision model, DB1 would be a baby step
towards more autonomous and efficient real world IDM applications.Comment: 26 pages, 4 figure

Multilevel Inverter Compensation System of the Single-phase Based on Instantaneous P-instantaneous Real Power and Q-instantaneous Virtual Power Theory
This paper gives an introduction to the single-phase instantaneous PQ (P-instantaneous real power and Q-instantaneous virtual power) theory and carries out the calculation and simulation analysis on reactive power, active power, instantaneous reactive power and instantaneous active power for the single system before and after the compensation of the multilevel inverter. By analyzing the experimental results, it can be seen that harmonic current of the single phase system decreased significantly after using multilevel inverter, while the power factor improved obviously
Metallic behavior induced by slight N doping in Sr
The N-doped compounds with double perovskite structure were synthesized by ammonolysis method and are characterized by means of X-ray diffraction, magnetic and electrical resistivity measurements. The effect of dopant on the crystal structure, magnetic properties and electrical behavior was studied. Rietveld analysis shows that for N-doped samples the unit-cell parameters, a and c, first decrease, then increase with ammonolyzed time. Thermal magnetization shows that the spontaneous magnetization for all samples follows Bloch’s law in low temperature range. The spin wave stiffness constant, Dsw, increases with ammonolyzed time from 0 to 8 h, followed by a sharp decrease with ammonolyzed time from 8 to 10 h. Isothermal magnetization for N-doped samples demonstrates that the saturation magnetic moments at different temperatures first increase, then decrease with N doping. The resistivity increases with ammonolyzed time from 3 to 10 h. For slight N-doped samples the electrical resistivity demonstrates metallic behavior and electrical transport behavior for all samples shows the disordered characteristic. The degree of B-site cationic order in N-doped samples is lower than that in N-undoped sample

The Effects of NAA on the Tuberous Root Yield and Quality of Rehmannia glutinosa and Its Regulatory Mechanism by Transcriptome and Metabolome Profiling
Naphthylacetic acid (NAA) was used to increase the tuberous root yield of Rehmannia glutinosa, but the differences between its NAA-treated and control tuberous roots (NT and CG) and the regulatory mechanism of NAA effect remain unclear. In order to investigate them, NTs and CGs were used as materials, and both yield-related indices were measured; the metabolomics and transcriptomics were used to capture differentially accumulated metabolites (DAM) and to validate them via mining differentially expressed genes (DEGs), respectively. The effects of NAA treatment: increased NT mass per plant by 21.14%, through increasing the number of roots and increasing the mean root diameter; increased catalpol content by 1.2234% (p < 0.05); up-regulated 11DAMs and 596DEGs; and down-regulated 18 DAMs and 517DEGs. In particular, we discovered that NAA regulated its DAMs and biomass via 10 common metabolic pathways, and that the number of NAA-down-regulated DAMs was more than that of NAA-up-regulated DAMs in its tuberous root. Furthermore, HPLC validated the changes of several DAMs and 15 DEGs (4CL, ARF, CCoAOMT, ARGOS, etc.) associated with the yield increase and DAMs were verified by RT-qPCR. This study provided some valuable resources, such as tuberous root indices, key genes, and DAMs of Rehmannia glutinosa in response to NAA for distinguishing the CGs from NTs, and novel insights into the regulatory mechanism of NAA effects on both at the transcriptomic and metabolomic levels, so it will lay a theoretical foundation for NAA-regulated plant yield and quality, and provide references for prohibiting the uses of NAA as a swelling agent in medicinal tuber plants in China

Comparative Proteomic Analysis of Aqueous Humor Reveals Biochemical Disparities in the Eyes of High Myopic Patients
Myopia accounts for a significant
proportion of visual lesions
worldwide and has the potential to progress toward pathological myopia.
This study aims to reveal the difference in protein content in aqueous
humor between high myopic and nonhigh myopic patients, as well as
better understand the dysregulation of proteins in myopic eyes. Aqueous
humor was collected for liquid chromatograph mass spectrometer (LC/MS)
analysis from 30 individual eyes that underwent phacoemulsification
and intraocular lens (IOL) implantation. Results showed that a total
of 190 differentially expressed proteins were identified, which revealed
their involvement in cell metabolism, immune and inflammatory response,
and system and anatomical structure. Further analysis focused on 15
intensively interacted hub proteins, encompassing functions related
to complement cascades, lipoprotein metabolism, and fibrin biological
function. Subsequent validations demonstrated elevated levels of APOE
(apolipoprotein E), C3 (complement 3), and AHSG (α-2-HS-glycoprotein)
in the high myopia group (31 eyes of cataracts and 45 eyes of high
myopia with cataracts). AHSG had a significant positive correlation
with axial length in high myopic patients, with good efficacy in distinguishing
between myopic and nonmyopic groups. AHSG may be a potential indicator
of the pathological severity and participator in the pathological
progress of high myopia. This study depicted differential expression
characteristics of aqueous humor in patients with high myopia and
provided optional information for further experimental research on
exploring the molecular mechanisms and potential therapeutic targets
for high myopia. Data are available via ProteomeXchange with the identifier
