Physical AI needs to be trained digitally first. It a digital twin of itself, the policy model, and world, world model. In this paper, we present Cosmos World Foundation Model Platform help developers build customized models for their setups. We position foundation model as general-purpose that can fine-tuned into downstream applications. Our platform covers video curation pipeline, pre-trained models, examples post-training tokenizers. To builders solve most critical problems our society,...
ABSTRACT Humic acid (HA) might benefit plant growth by improving nutrient uptake and hormonal effects. The effect of HA on growth, macro—and micronutrient contents, postharvest life gerbera (Gerbera jamesonii L.) cv. ‘Malibu’ were examined. Different levels humic (0, 100, 500, 1000 mg/L) applied to solution. Root increased at mg/L incorporated into the Macro- contents leaves scapes including nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn)...
Abstract Potassium (K) deficiency in soils is widespread and has become one of the most nutritional limiting factors for increasing rice yield China Asia. Improving K use efficiency by exploiting genetic potential largely depends on understanding physiological mechanisms underlying lowland rice. In this study, internal (KIUE) at low supply relative to accumulation distribution, tillering grain filling rates, dry matter allocation were examined under field conditions. The concentrations upper...
When hedging longevity risk with standardized contracts, the hedger needs to calibrate hedge carefully so that it can effectively reduce risk. In this article, we present a calibration method is based on matching mortality rate sensitivities. Specifically, introduce measure called key q-duration, which allows us estimate price sensitivity of life-contingent liability each portion underlying curve. Given measure, one easily construct small number q-forward contracts. We further propose an...
The effect of potassium (K) on ferrous iron (Fe2+) toxicity in hybrid rice (Oryza sativa L.) was investigated this study. Plants were grown nutrient solution with three K supplies (0.26, 0.51, and 1.02 mM) five Fe2+ levels (0.09, 0.18, 0.36, 0.54, 0.90 mM). Excessive greatly decreased root shoot dry weights, length, height the rice, depression obvious even at relatively low (above 0.18 notably influenced morphological parameters concentrations K, phosphorus (P), nitrogen (N) plants. High...
Abstract This study examined the effects of organic manure and chemical fertilizer on soil microflora, respiration, number inorganic phosphate solubilizing bacteria, phosphorus (P) mineralizing bacteria. The rate, P selected enzyme activities in a blue purple paddy were also studied. results showed that significantly increased total fungi, actinomyces, rate respiration activities, whereas resulted smaller effect, bacteria affected more than fungi actinomyces by manure. enhancement biological...
Potassium is an important nutrient in plant growth and development of rice ( Oryza sativa L.), but K availability may be seriously limited developing countries. Genotypic variation tolerance to Iow‐K stress has been shown. This study was conducted investigate the genetic basis for low‐K identify quantitative trait loci (QTLs) that provide this tolerance. On preliminary tests, seedlings 123 double haploid (DH) lines their parents (which differed response supply) ‘IR64’, indica cultivar...
Experiments were conducted to determine the effect of solid levels on natural sedimentation swine manure. Total solids (TS) 0.5, 1.0, 2.0, 4.0, and 6.0% evaluated. Natural was impeded at higher than 2.0% also lower 1.0% TS concentrations. Two flocculants (ferric chloride aluminum sulfate) commonly used in municipal wastewater treatment industry then evaluated for their enhancement concomitant removal phosphorus from Each flocculant five levels—0 (control), 500, 1,000, 1,500, 2,000 mg/L—on...
Multi-soil-layering (MSL) systems permit higher hydraulic load rates (HLR) and pollutant loads than some conventional soil by forming the alternating structures inside to enhance filtration ability of soil. However, quantitative evaluations water movement in MSL are insufficient be understood. Residence time distribution (RTD) is a tool characterize mixing flow within reactors useful for troubleshooting existing reactors. In this study, pulse tracer tests were conducted determine RTD...
Fresh swine manure was sieved into seven different particle size categories, i.e., <0.075 mm, < 0.15 0.25 0.5 min, 1.0 1.4 and 2.0 mm. Manure stored in PVC columns sampled every 5 days up to 30 days. samples were analyzed for total volatile fatty acids (VFAs), 5-day biochemical oxygen demand (BOD5), solids (TS), suspended (TSS), (TVS). Two parameters (VFAs BOD5) used determine the odor generation potential of test manure. The results showed that VFAs correlated well with BOD5 (R2 = 0.8297)....
Sedum alfredii Hance is a fast-growing and high-biomass zinc (Zn) hyperaccumulator native to China. A compound containing substituted indole ligand was isolated from this Zn plants by sonication/ethanol extraction, macroporous resin column as well preparative HPLC (P-HPLC). Hydroponic experiment showed that the concentrations of both were remarkably increased in stems leaves non-hyperaccumulator rising 0.5 50 μmol L−1, with much more than non-hyperaccumulator. At L−1 Zn, grew normally but...
A laboratory study revealed the dynamic changes of solids in swine manure during storage order todetermine best time for efficient solid-liquid separation treatment. Data showed that should be conductedwithin 10 days after excretion particle sizes equal to or greater than 0.5 mm and within five particlesizes smaller mm. After first storage, total suspended tended decomposed at ahigher rate, thus reducing efficiency. Particles 0.25 were biologicallydecomposed same rate without relevance size...
