In this paper, we present a novel global reordering model that can be incorporated into standard phrase-based statistical machine translation. Unlike previous local reordering models that emphasize the reordering of adjacent phrase pairs (Till-mann and Zhang, 2005), our model explicitly models the reordering of long distances by directly estimating the(More)
We experimentally demonstrate that hybridized nanocavities in optically thick metal films radiate in coherence, and act as an efficient single-polarized plasmonic nano-antenna array. We employ propagating and localized plasmons to enhance polarization control along one axis, with total suppression of the perpendicular polarization component. The(More)
We introduce a compact submicron structure consisting of multiple optical microcavities at both the entrance and exit sides of a subwavelength plasmonic slit filled with an absorbing material. We show that such microcavity structures at the entrance side of the slit can greatly enhance the coupling of the incident light into the slit, by improving the(More)
INTRODUCTION Hepatitis B virus (HBV) flare is a serious problem following hematopoietic stem cell transplantation (HSCT), and the mortality rate is high if severe hepatitis occurs. CASE DESCRIPTION Although Entecavir (ETV) is a standard antiviral drug for HBV infection, the efficacy and safety of ETV therapy in HSCT are still unclear. DISCUSSION AND(More)
To identify factors affecting transplant outcome, data from 65 Philadelphia Chromosome-positive acute lymphoblastic leukemia (Ph + ALL) patients who had undergone allogeneic hematopoietic transplantation (allo-HSCT) in our institution were analyzed. The probability of OS (overall survival) and DFS (disease free-survival) at 3 years after allo-HSCT was 40.1(More)
We demonstrate 3D surface plasmon photoresponse in nanopillar arrays resulting in enhanced responsivity due to both Localized Surface Plasmon Resonances (LSPRs) and Surface Plasmon Polariton Bloch Waves (SPP-BWs). The LSPRs are excited due to a partial gold shell coating the nanopillar which acts as a 3D Nanopillar Optical Antenna (NOA) in focusing light(More)
A high-flow nasal cannula (HFNC) is a newly developed device that enables high-flow oxygen therapy for patients with serious cardiopulmonary problems, but there are few data regarding its use in patients with hematological disease. The efficacy and tolerability of HFNCs for patients who developed ARF during the treatment of various hematological diseases(More)
Acute graft-versus-host disease (aGVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Because diagnosis of aGVHD is exclusively based on clinical symptoms and pathological findings, reliable and noninvasive laboratory tests for accurate diagnosis are required. An activating immunoreceptor, DNAM-1 (CD226), is(More)
To clarify the clinical impact of prior use of azacitidine (AZA) on outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for myelodysplastic syndrome (MDS), we retrospectively reviewed the clinical outcomes of 15 MDS patients who were treated with AZA before allo-HSCT (AZA group). We compared the outcomes of these 15 patients with 52(More)
