A Milestone in Codifying the Wisdom of Traditional Oriental Medicine: TCM, Kampo, TKM, TVM—WHO International Standard Terminologies on Traditional Medicine in the Western Pacific Region
The WHO published a dictionary-type book entitled ‘WHO International Standard Terminologies on Traditional Medicine in the Western Pacific Region’ which has a total of 3259 technical terms which have been commonly used in traditional Chinese (TCM), Japanese (Kampo), Korean (TKM) and Vietnamese (TVM) medicines. In this comprehensive guide, each term has the English expression, the original Chinese character and a concise English definition. The book covers 3106 terms from basic theories, diagnostics, diseases, various therapeutics including acupuncture and moxibustion and even the English wording of 153 titles which are considered the most important traditional medical classics published in these four countries. A prominent feature of the compilation is the codification format that assigns numbers in hundred decimal units for each category of the section. This type of coding system provides the flexibility for adding more terminologies in the future and is useful for constructing a database for the retrieval of various published scientific articles. Overall, the usage of these standard terminologies is highly desirable to deliver accurate meanings, and ultimately to avoid a variety of expressions for a single term in different scientific manuscripts on Oriental medicine
Evidence for a preformed Cooper pair model in the pseudogap spectra of a Ca10(Pt4As8)(Fe2As2)5 single crystal with a nodal superconducting gap
For high-Tc superconductors, clarifying the role and origin of the pseudogap
is essential for understanding the pairing mechanism. Among the various models
describing the pseudogap, the preformed Cooper pair model is a potential
candidate. Therefore, we present experimental evidence for the preformed Cooper
pair model by studying the pseudogap spectrum observed in the optical
conductivity of a Ca10(Pt4As8)(Fe2As2)5 (Tc = 34.6 K) single crystal. We
observed a clear pseudogap structure in the optical conductivity and observed
its temperature dependence. In the superconducting (SC) state, one SC gap with
a gap size of {\Delta} = 26 cm-1, a scattering rate of 1/{\tau} = 360 cm-1 and
a low-frequency extra Drude component were observed. Spectral weight analysis
revealed that the SC gap and pseudogap are formed from the same Drude band.
This means that the pseudogap is a gap structure observed as a result of a
continuous temperature evolution of the SC gap observed below Tc. This provides
clear experimental evidence for the preformed Cooper pair model.Comment: 15 pages, 4 figure
Tensile Behavior and Cracking Pattern of an Ultra-High Performance Mortar Reinforced by Polyethylene Fiber
This paper presents an experimental study of the compressive strength, tensile behavior (including the tensile strength, tensile strain capacity, and toughness), and cracking patterns of an ultra-high performance mortar (UHPM) reinforced by polyethylene (PE) fiber as well as a discussion of the different tensile behaviors of the UHPM according to the types and contents of fibers used. The UHPM reinforced by microsteel fiber of 1.5 vol% and the UHPM reinforced by PE fibers with three different fiber contents were designed and prepared. A series of experiments was undertaken to assess the effect of PE fiber on the properties of the UHPM. The results found a lower strength level, higher tensile strain capacity and toughness, and a larger crack width in the PE fiber-reinforced UHPM compared to microsteel fiber-reinforced UHPM. It was also demonstrated that tensile strain capacity and toughness of 4.05% and 0.454 MPa m/m, respectively, can be attained when using the proposed polyethylene-fiber-reinforced UHPM
Poset modules of the -Hecke algebras and related quasisymmetric power sum expansions
Duchamp--Hivert--Thibon introduced the construction of a right
-module, denoted as , for any partial order on the set .
This module is defined by specifying a suitable action of on the set
of linear extensions of . In this paper, we refer to this module as the
poset module associated with . Firstly, we show that has a Hopf algebra structure that is isomorphic to the
Hopf algebra of quasisymmetric functions, where is the full
subcategory of whose objects are direct sums of finitely
many isomorphic copies of poset modules and is the
Grothendieck group of . We also demonstrate how
(anti-)automorphism twists interact with these modules, the induction product
and restrictions. Secondly, we investigate the (type 1) quasisymmetric power
sum expansion of some quasi-analogues of Schur functions, where
is a composition. We show that they can be expressed as the sum of the
-partition generating functions of specific posets, which allows us to
utilize the result established by Liu--Weselcouch. Additionally, we provide a
new algorithm for obtaining these posets. Using these findings, for the dual
immaculate function and the extended Schur function, we express the
coefficients appearing in the quasisymmetric power sum expansions in terms of
border strip tableaux.Comment: 42 page
The projective cover of tableau-cyclic indecomposable -modules
Let be a composition of and a permutation in
. This paper concerns the projective covers of
-modules , and
, which categorify the dual immaculate
quasisymmetric function, the extended Schur function, and the quasisymmetric
Schur function when is the identity, respectively. First, we show that
the projective cover of is the projective indecomposable
module due to Norton, and and the -twist
of the canonical submodule of

conditions appear as -homomorphic images of .
Second, we introduce a combinatorial model for the -twist of
and derive a series of surjections starting from
to the -twist of
. Finally, we construct the projective
cover of every indecomposable direct summand of
. As a byproduct, we give a characterization of
triples such that the projective cover of
is indecomposable.Comment: 41 page
Homological properties of 0-Hecke modules for dual immaculate quasisymmetric functions
Let be a nonnegative integer. For each composition of , Berg
introduced a cyclic indecomposable -module
with a dual immaculate quasisymmetric function as the
image of the quasisymmetric characteristic. In this paper, we study
's from the homological viewpoint. To be precise, we
construct a minimal projective presentation of and a
minimal injective presentation of as well. Using them, we
compute and , where is
the simple -module attached to a composition of . We also
compute when
and , where represents the lexicographic
order on compositions.Comment: 44 pages, to be published in Forum of Math: Sigm
The origin of proinflammatory cytokines in patients with idiopathic dilated cardiomyopathy.
Proinflammatory cytokines and their receptors are increased in the peripheral blood of patients with heart failure. We measured cytokines and their receptors in systemic artery (SA), coronary sinus (CS) and infra-renal inferior vena cava (IVC), in order to investigate their origin and influential factors. Thirty patients with idiopathic dilated cardiomyopathy were performed echocardiography at admission, and right heart catheterization after stabilization. Blood was drawn from 3 sites for measurement of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and soluble tumor necrosis factor-alpha receptor (sTNFR) I, II. TNF-alpha at CS (3.25 +/- 0.34 pg/mL) was higher than those of SA (1.81 +/- 0.39 pg/mL) and IVC (1.88 +/- 0.38 pg/mL, p<0.05). IL-6 at CS (18.3 +/- 3.8 pg/mL) was higher than that of SA (5.8 +/- 1.2 pg/mL, p<0.01). The levels of sTNFR I, II showed increasing tendency in sequence of SA, IVC and CS. TNF-alpha and sTNFR I, II from all sites were proportional to worsening of functional classes at admission (p<0.05). E/Ea by Doppler study at admission, which reflects left ventricular end-diastolic pressure (LVEDP) was positively correlated with TNF-alpha from SA (R=0.71, p<0.01), CS (R=0.52, p<0.05) and IVC (R=0.46, p<0.05). Thus, elevated LVEDP during decompensation might cause cytokine release from myocardium in patients with idiopathic dilated cardiomyopathy
Test of the reaction mechanism for gamma N -> K Lambda(1520) using the polarized photon
We study the reaction mechanism for the photoproduction of the Lambda(1520),
based on an effective Lagrangian approach. We investigate each contribution of
the s-, u-, t-channel processes and contact term, separately. One of the most
characteristic features of this reaction is the contact-term dominance which
governs the photoproduction from the proton, when the K*-exchange contribution
is possibly not too large. We suggest several different ways of the
polarizations and arrangement of the beam and target to make to understand the
role of each contribution separately in future experiments.Comment: 10 pages, 14 figures, accepted for publication in PR
