Distributed Denial-of-Service (DDoS) attack detection systems are classified into a signature based approach and an anomaly based approach. However, such methods tend to suffer from low responsiveness. On the other hand, real-time burst detection which is used in data mining offers two advantages over traditional statistical methods. First, it can be used for real-time detection when an event is occurring, and second, it can work with less processing as information about events are compressed, even if a large number of events occur. Here, the authors add the function for attack detection in real-time burst detection technique, and propose a highly responsive DDoS attack detection technique. This paper performs experiments to evaluate its effectiveness, and discusses its detection accuracy and processing performance.

Background: The independent role of serum triglyceride (TG) levels as a cardiovascular risk factor is still not elucidated. We aimed to investigate if the effect of TG on arterial stiffness is influenced by the serum level of low-density lipoprotein cholesterol (LDL-C). Methods and Results: We studied 11,640 subjects who underwent health checkups. They were stratified into 4 groups according to LDL-C level (≤79, 80–119, 120–159, and ≥160 mg/dL). Arterial stiffness was evaluated by brachial-ankle pulse wave velocity (baPWV). In each group, univariate and multivariete logistic regression analyses were performed to investigate the association between high TG (≥150 mg/dL) and high baPWV (>1,400 cm/s). In the univarite analysis, high TG was significantly associated with high baPWV in LDL-C <79 mg/dL (OR, 3.611, 95% CI, 2.475–5.337; P<0.0001) and 80–119 mg/dL (OR, 1.881; 95% CI, 1.602–2.210; P<0.0001), but not in LDL-C 120–159 mg/dL and ≥160 mg/dL. In the multivariate analysis, high TG was significantly associated with high baPWV in LDL-C ≤79 mg/dL (OR, 2.558; 95% CI, 1.348–4.914; P=0.0040) and LDL-C 80–119 mg/dL (OR, 1.677; 95% CI, 1.315–2.140; P<0.0001), but not in LDL-C 120–159 mg/dL and ≥160 mg/dL. Conclusions: High TG and increased arterial stiffness showed an independent relationship in a Japanese general population with LDL-C ≤119 mg/dL. TG-lowering therapy might be an additional therapeutic consideration in these subjects.

The fourth/tenth (A.H./C.E.) century is one of the most crucial time to the development of Ismā'īlī Shī'ism not only because the Fāṭimids' claim for the sole leadership (<i>Imāmah</i>) conflicts with its original belief in the advent of the messianic figure called the Qā'im, but because some thinkers adopted Greek thought, especially Neoplatonism. This article aims at contributing to elucidation of how the Ismā'īlī thinkers made consistent their doctrine on the Qā'im with newly adopted Neoplatonism in this important century, with special reference to Abū Ḥātim al-Rāzī's (d. ca 322/933-4) <i>Kitāb al-Iṣlāḥ</i>, one of the oldest extant Neoplatonist-influenced texts.<br>&emsp;The text of <i>al-Iṣlāḥ</i> suggests that the Qā'im will resume the full contact, which Adam had enjoyed, with the two highest hypostases of Neoplatonist cosmology, that is, the Universal Intellect and the Universal Soul. Also in his text al-Rāzī implies that the advent of the Qā'im will mark or bring the full actualization of the "spiritual forms" (<i>al-ṣuwar al-rūḥānīyah</i>) and "simple form" (<i>al-ṣurah al-basīṭah</i>) of the human soul. This is also the result of the influence of the "highest simple world," the realm of the two highest hypostases. Thus, with the background of Greek thought, especially Neoplatonism, al-Rāzī de-politicized the role and mission of the Qā'im. This idea is shared by al-Sijistani (d. after 361/971), Neoplatonist Ismā'īlī thinker who is nearly one generation younger than al-Rāzī. Did this shared idea of the de-politicized and "spiritualized" Qā'im function as precursor for Ḥamīd al-Dīn al-Kirmānī's (d. after 411/1020) own vision of the Qā'im and the postponing of his advent and the ultimate <i>eschaton</i>? This will be an issue of our future research.

In this study, we propose a method for determining the classroom seating arrangements considering relationships between one student and the other students sitting around him or her. The method for determining the classroom seating arrangements is constructed based on our proposed genetic algorithm. In order to determine the optimal classroom seating arrangements, the genetic algorithm is applied on the basis of the questionnaire result of how students feel when they take a class on the seats assigned to them and the analysis of each student's personality. Experiments are carried out in order to verify the effectiveness of the proposed method.

To clarify the morphological and phylogenetic differentiation of Bandona boninensis Suzuki 1974 in Chichi-jima Island of the Bonin (Ogasawara) group of Islands, we studied the external morphological characters and performed sequencing of the cytochrome c oxidase subunit I (COI) gene of mitochondrial DNA (mtDNA) and 28S rRNA of nuclear DNA (nrDNA). The sequences of COI and 28S rRNA were identical among the individuals of B. boninensis. These results suggest that B. boninensis experienced a rapid expansion of its distribution in Chichi-jima Island without undergoing any morphological and molecular differentiation.著者らは小笠原諸島の父島に生息するムニンカケザトウムシBandona boninensis の形態的および系統的分化を明らかにするために、父島の4 地点から採集を行い、体長、触肢腿節の長さ、背甲長および背甲幅、鋏角長、第1~4 脚の腿節長といった形態計測を実施し、ミトコンドリアDNA のCOI 領域および核DNA の28SrRNA 領域に基づく系統樹を作成した。その結果, ムニンカケザトウムシのCOI および28S において塩基置換は見られなかった。この結果は、ムニンカケザトウムシが父島内で系統的分化をほぼ起こしていないことを示す。また、採集を行った個体がすべて雌個体であったことから、これまでの報告の通り、父島においては単為生殖種として生息している可能性が高い。

The aim of this study was to develop a practical method to analyze tetrodotoxin (TTX), quantitatively, from postmortem specimens, not only blood and urine, but also organs. Extraction was achieved with 2% acetic acid and the use of an anion-exchange solid-phase extraction (SPE) cartridge. The quantitation method was a standard addition method with a calibration curve consisting of at least 3 points and an internal standard, voglibose (VOG). Separation by LC-MS/MS was achieved using a Luna HILIC (Phenomenex) column. The mobile phase was acetonitrile: 5 mM ammonium formate buffer (95:5), delivered at 0.2 mL/min. The selected reaction monitoring (SRM) transitions for TTX and VOG were m/z 320>302 and m/z 268>92, respectively. Cleaner extracts were achieved by using a lipid removal cartridge and washing with heptane. The addition of steps to remove interfering components that are prominent in postmortem samples aided in successful analysis. The HILIC column improved the retention of TTX to greater than 2 min to avoid the area where ion suppression has its greatest effect. Also, the use of anion-exchange SPE lessened the influence of acetic acid used during extraction. By using this method, we were able to quantitate low levels of TTX in postmortem specimens.

It is well known dietary lactic acid bacteria (LAB) stimulates cell-mediated immunity such as natural killer (NK) activity in mice. Here, we aimed to assay the immunomodulatory effects of a cell preparation of Enterococcus faecalis strain KH-2 (CPEF). We further evaluated the possibility of antitumour activity caused by CPEF administration, because NK cells actively participate in the prevention of tumour formation. NK cell activity and gene expression of IFN-γ and Perforin 1, which were induced most likely by a synergetic action of their cytotoxic activity, were higher in splenocytes of CPEF-administered mice than they were in control mice. Moreover, unlike those of control mice, the splenocytes of CPEF-administered mice had significantly higher CD28+CD69+/CD4+ and CD28+CD69+/CD8+ ratios that resulted in a survival rate with a tendency toward improvement after 47 days of CPEF administration (p=0.1) in Meth-A fibrosarcoma-bearing mice. In conclusion, we showed that CPEF might be effective in treating Meth-A fibrosarcoma in mice, as it helped increase their survival rate via stimulation of an immune response in splenocytes, which involved systemic cellular immunity processes such as cytotoxic activity, and active T cells.

The polarization dependence of $2p \to 3d \to 2p$ resonant X-ray emission spectroscopy (RXES) in $3d^{1}$, $3d^{2}$ and $3d^{3}$ systems (TiF3, VF3 and Cr2O3, respectively) is measured and analyzed by means of the MX6 (M denotes a transition metal and X denotes a ligand, respectively) cluster model. The results are compared with a previous one for the $3d^{0}$ system (TiO2). Generally, with increasing $3d$ electron number, the spectral structure of RXES becomes more complicated by the influence of the crystal field and the multiplet coupling effect. Moreover, we point out that the selection rules on the polarization dependence of RXES change with the $3d$ electron number and that a drastic resonance enhancement corresponding to the excitation to an antibonding state in the $3d^{0}$ system is almost absent for the $3d^{n}$ systems with $n = 1$, 2 and 3.

沖縄県においてヒマワリは景観の良さから観光資源として,さらには,地力回復用の緑肥として注目されている.そのヒマワリ栽培を油糧生産と遊休農地の解消の一助となると考え,播種期の違いが収量に与える影響について比較検討した.春播き栽培では,栽培期間中の気温,日射量,降水量,台風接近数および開花に要する積算温度が高く,発芽日から開花日までの日数が短かった.また,花芽形成期から開花期の間のCGRおよびLAIが低く,乾物収量,子実収量はそれぞれ705,177 kg 10a_-1と秋播き栽培に比べて低くなった.これは夏季の高温・高日射により栄養成長が不十分なまま開花し,子実肥大が遅れたことが原因と考えられた.一方,秋播き栽培では,花芽形成期から開花期までのCGRおよびLAIが高く,乾物収量,子実収量はそれぞれ1274,246 kg 10a-1と高かった.太陽エネルギー利用効率が植物体全体および子実に関してそれぞれ2.11,0.64%といずれも春播き栽培に比べて2倍以上高くなった.これは開花期までの成長期間と低温・低日射でも高い葉面積を確保できたことが原因と考えられた.以上より,沖縄においては,秋冬に降雪・降霜がなく,夏季の高温・高日射・台風を避けられるため,秋播き栽培も有用であると考えられた.

Background:The objective of the present analyses was to describe the baseline characteristics and treatment of the Japanese patients with HFrEF in THE PARALLEL-HF study.Methods and Results:Key demographic, clinical and laboratory findings, along with treatment, were reported and compared with patients enrolled in the PARADIGM-HF trial and other contemporary randomized clinical trials and registries of Japanese patients with HFrEF. In addition, the MAGGIC and EMPHASIS-HF risk scores were calculated. A total of 225 Japanese patients were randomized in PARALLEL-HF with a mean age of 67.9 years and the majority of the patients being male (85.8%) and in NYHA Class II (93.8%). Key baseline characteristics in PARALLEL-HF were generally comparable with PARADIGM-HF, and other contemporary clinical trials and registries of Japanese HFrEF patients. Patients enrolled in PARALLEL-HF were well treated with conventional evidence-based therapy at baseline (angiotensin-converting enzyme inhibitor inhibitor/angiotensin receptor blocker, 62.7%/37.3%; β-blockers, 94.7%; mineralocorticoid receptor antagonist, 59.1%). Despite the evidence-based treatment and most patients being in NYHA Class II, these patients had a low LVEF (mean 28.1%) and were at high risk of cardiovascular mortality and morbidity as assessed by the MAGGIC and EMPHASIS-HF risk scores.Conclusions:Overall, the patients in PARALLEL-HF were largely representative of contemporary ambulatory patients with HFrEF who are well treated with evidence-based therapies. PARALLEL-HF will determine whether sacubitril/valsartan provides similar improvements in clinical outcomes in Japanese HFrEF patients as observed in the PARADIGM-HF study.

Objective: Comprehensive profiling of gene expression in peripheral blood leucocytes (PBLs) in patients with acute coronary syndrome (ACS) as a prognosticator is needed. We explored the specific profile of gene expression in PBLs in ACS for long-term risk stratification. Methods: 30 patients with ACS who underwent primary percutaneous coronary intervention (PCI) and 15 age-matched adults who participated in medical check-ups were enrolled from three centres. Peripheral blood samples were collected to extract RNA for microarray analyses. Results: During the 5-year follow-up, 36% of this cohort developed the expected non-fatal coronary events (NFEs) of target lesion revascularisation (TLR) and PCI for a de novo lesion. Class comparison analysis (p<0.005) demonstrated that 83 genes among 7785 prefiltered genes (41 upregulated vs 42 downregulated genes) were extracted to classify the patients according to the occurrence of NFE. Pathway analysis based on gene ontology revealed that the NFEs were associated with altered gene expression regarding the T-cell receptor signalling pathway in ACS. Univariate t test showed that the expression level of death-associated protein kinase1 (DAPK1), known to regulate inflammation, was the most significantly negatively regulated gene in the event group (0.61-fold, p<0.0005). Kaplan-Meier curve analysis and multivariate analysis adjusted for baseline characteristics or clinical biomarkers demonstrated that lower DAPK1 expression in PBL emerged as an independent risk factor for the NFEs (HR: 8.73; CI 1.05 to 72.8, p=0.045). Conclusions: Altered gene expression in T-cell receptor signalling in PBL in ACS could be a prognosticator for secondary coronary events. © Published by the BMJ Publishing Group Limited.

Acromegalic arthropathy is a common complication of acromegaly and harms the quality of life of the patients even after acromegaly is in long-term remission. A recent study demonstrated by knee MRI the characteristic structural features of acromegalic arthropathy. However, the effects of treatment for acromegaly on such structural features are almost unknown. This study was undertaken to analyze the effects of transsphenoidal surgery (TSS) on acromegalic arthropathy and elucidate whether knee MRI findings are reversible or irreversible. We analyzed 22 patients with acromegaly (63.7% females, median age 58 years) by knee MRI at diagnosis. Out of these 22 patients, 16 who underwent TSS (68.9% female, median age 58 years) were also subjected to knee MRI 2 months after TSS. As for X-ray undetectable findings, MRI detected synovial thickening, bone marrow lesion, ligament injury and meniscus injury in 22.7%, 22.7%, 4.7% and 59.1% of the patients, respectively. With respect to the 16 patients who underwent TSS, clinical and structural improvements were observed respectively in 100%, 66.7% and 66.7% of the patients who showed knee joint pain, synovial thickening and bone marrow lesion before TSS. However, no patient showed structural improvement of meniscus injury after TSS. In acromegalic arthropathy, synovial thickening and bone marrow lesions are reversible while meniscus injury is irreversible. Because all those findings are associated with the exacerbation of arthropathy, they may be therapeutic targets for preventing the progression of arthropathy by endocrinological and orthopedic intervention.
