Kostka functions K_(λ,μ)~±(t), indexed by r-partitions λ and μ of n, are a generalization of Kostka polynomials K_(λ,μ)(t) indexed by partitions λ,μ of n. It is known that Kostka polynomials have an interpretation in terms of Lusztig's partition function. Finkelberg and Ionov(2016) defined alternate functions K_(λ,μ)(t) by using an analogue of Lusztig's partition function, and showed that K_(λ,μ)(t) ∈Z≥0[t] for generic μ by making use of a coherent realization. They conjectured that K_(λ,μ)(t) coincide with K_(λ,μ)^-(t). In this paper, we show that their conjecture holds. We also discuss the multi-variable version, namely, r-variable Kostka functions K_(λ,μ)~±(t_1,…,t_r).

Roles of rare earth oxide （RE2O3） additives in millimeter-wave（MM） sintering of AIn were investigated from the standpoints of phase diagram, heating characteristics of rare earth oxides, and morphology of intergranular oxide phase. In the millimeter-wave sintering of AIn, densification temperature decreased with the decrease of the ionic radius of rare earth ion and was closely related with the eutectic temperature in the RE2Oa-Al2O3 binary system. The lowest densification temperature in the millimeter-wave sintering of AIn with Yb2O3 additive was attributed to the largest heating rate of Yb2O3-Al2O3 binary oxide under millimeter-wave radiation. Furthermore, the lowest densification temperature could be attained while selecting the Yb2O3 content so as to form the intergranular phase with the eutectic composition in the Yb2O3-Al2O3 binary system. The result showed good agreement with the above mentioned during the sintering of Si3n4 with Yb2O3-Al2O3 additive. From TEM observation, it was verified that film-like intergranular oxide phase formed under millimeter-wave radiation was favorable for attaining high thermal conductivity in the Yb2O3 added AIns.

Background: In general, para-aortic lymph node(Ln16) metastasis has been considered as a contraindication for pancreatic resection. However, some pancreatic cancer patients with Ln16 metastasis have been reported to survive for longer than expected after pancreatectomy. The purpose of this study was to determine whether pancreatic cancer patients with Ln16 metastasis might benefit from ***: We retrospectively reviewed 201 consecutive patients with invasive pancreatic ductal adenocarcinoma who underwent surgery at Osaka national Hospital between April 2003 and December *** patients included 22 patients with Ln16 metastasis who underwent an extended lymphadenectomy and 25 patients who underwent a palliative surgical biliary and gastric bypass. The clinicopathological data and outcomes were evaluated using univariate and multivariate ***: The overall survival of the patients with Ln16 metastasis was poorer than that of the Ln16-negative patients(P = 0.0014). An overall survival analysis of the Ln16-positive patients stratified according to the preoperative CA19-9 level showed a significant difference between patients with a low preoperative CA19-9 level(≤360 U/mL) and those with a high preoperative CA19-9 level(>360 U/mL)(P = 0.0301). no significant difference in overall survival of patients was observed between those with Ln16 positivity and those who underwent bypass surgery. However, the overall survival of the Ln16-positive patients with a CA19-9 level ≤360 U/mL(n = 11) was significantly higher than that of those who underwent bypass surgery(P = 0.0452).Conclusion: Surgical resection and extended lymphadenectomy remains an option for pancreatic cancer patients with Ln16-positivity whose CA19-9 level is ≤360 U/mL.

In order to further reduce CO2 emission in ironmaking, utilization of a large amount of hydrogen to a blast furnace would be essential in the future. In this work, influence of hydrogen half substitute to bosh gas on reaction behavior of sinter under a blast furnace simulated condition was examined until 1400℃ using a laboratory reactor. In the reactor with electric heating parts, two pieces of sinter（15mmφx10mm size） were set inside a graphite crucible（18mm inner dia.） and heated up under 1 kg load until 1400℃ according to a heating pattern with a thermal reserve zone temperature 1000℃ in gas flow conditions with or without hydrogen half substitute to basic bosh gas n2-CO-CO2. Reduction of sinter finalized around 1100℃ in the condition of H2 substitute, while the reduction retarded around these temperatures in the condition without H2 substitute, being likely because low melting slag containing residual FeO was formed due to weaker reduction power of CO than hydrogen. The condition of H2 substitute provided higher carbon contents in sinter after reduction than the condition without H2 substitute. This is likely because hydrogen promoted carburization to solid iron with CO gas and provided more amounts of reduced irons. The condition of H2 substitute improved softening melting behavior of sinter by nearly 70℃, being likely because the condition inhibited the formation of the low melting slag. Furthermore, from analysis based on List model it was evaluated that an operation with half substitute of hydrogen to a basic bosh gas gave less coke rate 346 kg/thm and less BF production 7945 t/day compared with 461kg/thm and 8999 t/day in a basic operation. The results will be overall compared and discussed to aim at an innovative high productivity with H2 half substitute to bosh gas in a blast furnace.

Although the nicotinamide nucleotides nAD（H） and nADP（H） are essential for various metabolic reactions that play major roles in maintenance of cellular homeostasis, the significance of nAD biosynthesis is not well under- stood. Here, we investigated the dynamics of pollen nicotinamide nucleotides in response to imbibition, a representative germination cue. Metabolic analysis with capillary electrophoresis electrospray ionization mass spectrometry revealed that excess amount of nAD＊ is accumulated in freshly harvested dry pollen, whereas it dramatically decreased immedi- ately after contact with water, importantly, excess of nAD~ impaired pollen tube growth. Moreover, nAD~ accumulation was retained after pollen was imbibed in the presence of nAD^-consuming reaction inhibitors and pollen germination was greatly retarded. Pollen deficient in the nicotinate/nicotinamide mononucleotide adenyltransferase （nMnAT） gene, encoding a key enzyme in nAD biosynthesis, and a lack of nAD＊ accumulation in the gametophyte, showed precocious pollen tube germination inside the anther Iocule and vigorous tube growth under high-humidity conditions. Hence, the accumulation of excess nAD＊ is not essential for pollen germination, but instead participates in regulating the timing of germination onset. These results indicate that nAD＋ accumulation acts to negatively regulate germination and a decrease in nAD＋ plays an important role in metabolic state transition.

Ophiocordyceps sinensis has been used as one of the most valuable traditional Chinese Medication. This fungus parasitizes larva of Hepialus armoricanus, and converts each larva into a sclerotium form, in which the fruit body grows. Due to the geographical limitation, where O. sinensis can only be found in Himalayas region, the natural resources are limited and very expensive. This research aims to compare the growth-rate of O. sinensis mycelia with different ingredients mix with agar media using one-factor-at-a-time method. This research demonstrated the mycelial growth-rate with different carbon sources, including monosaccharide (Fructose, Glucose), disaccharide (Maltose, Sucrose), and polysaccharide (Dextrin, Malt extract), complex organic nitrogen sources, including beef extract, yeast extract, whey protein, and soy protein, and eight different carbon to nitrogen ratios. The objective of this research is to find out the suitable carbon and organic complex nitrogen sources and ratio for the O. sinensis solid cultivation. As results, O. sinensis grew best with disaccharides comparing to the other types of carbon sources. Furthermore, O. sinensis preferred whey protein in contrast to other organic complex nitrogen sources. As for the carbon to nitrogen ratios, an optimal ratio of 18:1 was observed. Based on those experiments, carbon source shows a greater influence for the mycelial growth. Hence many different types of grains and cereals would be great candidates as the main ingredients for the O. sinensis solid cultivation.

QUEST has a divertor configuration with a high and a negative n-index, and the problem of plasma vertical position instability control in QUEST is still under extensive study for achieving high efficiency plasma. The instability we considered is that the toroidal plasma moves either up or down in the vacuum chamber until it meets the vessel wall and is extinguished. The actively controlled coils （HCU and HCL） outside the vacuum vessel are serially connected in feedback with a measurement of the plasma vertical position to provide stabilizing control. In this work, a robust controller is employed by using the loop synthesis method, and provides robust stability over a wide range of n-index. Moreover, the gain of the robust controller is lower than that of a typical proportional derivative （PD） controller in the operational frequency range; it indicates that the robust controller needs less power consumption than the PD controller does.
