Abstract

We report a systematic study of free-space terahertz (THz) emission from photoconductive antennas (PCAs) nanodecorated with gold nanoparticles (Au-NPs) deposited by using the pulsed laser deposition (PLD) technique. H-shaped dipole micro-structured PCAs fabricated on semi-insulating GaAs substrates were decorated under various PLD conditions. Thus, by increasing the number of laser ablation pulses (NLP) of the Au target, both the average size of Au-NPs and the surface loading of PCAs increase. Compared with non-decorated PCAs, those decorated with Au-NPs exhibit significant enhancement in the radiated THz pulse amplitude. A maximum enhancement of ∼2.3 was achieved at NLP = 1250. Under this optimal NLP condition, not only is the average Au-NP size (of ∼15 nm) favorable for light absorption via localized surface plasmons, but also the inter-distance between NPs, the light reflectance, and facilitated transport of photocarriers, all combine to yield a stronger THz field emission. For higher NLP (≥2000), NPs coalesce and tend to form continuous film NPs, which not only significantly limits the light scattering toward the GaAs underlying substrate, but also electrically shorts the PCA. Finally, the Au-NP decoration of GaAs PCAs was also found to improve their overall thermal conductivity, making them much more thermally stable than their non-decorated counterparts.

Abstract

Precise measurement of neutrino beam direction and intensity was achieved based on a new concept with modularized neutrino detectors. INGRID (Interactive Neutrino GRID) is an on-axis near detector for the T2K long baseline neutrino oscillation experiment. INGRID consists of 16 identical modules arranged in horizontal and vertical arrays around the beam center. The module has a sandwich structure of iron target plates and scintillator trackers. INGRID directly monitors the muon neutrino beam profile center and intensity using the number of observed neutrino events in each module. The neutrino beam direction is measured with accuracy better than 0.4 mrad from the measured profile center. The normalized event rate is measured with 4% precision., Comment: 32 pages, 27 figures, submitted to Nucl. Instr. and Meth. A

Abstract

Hiromichi Yamane,1 Toshiyuki Kunisada,2 Toshifumi Ozaki,2 Nobuaki Ochi,1 Yoshihiro Honda,1 Yasunari Nagasaki,1 Nozomu Nakagawa,1 Tomoko Yamagishi,1 Hidekazu Nakanishi,1 Nagio Takigawa1 1Department of General Internal Medicine 4, Kawasaki Medical School, Okayama, Japan; 2Department of Orthopedics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama, Japan Purpose: “Rare cancer” is defined as malignancy with a disease prevalence (age-adjusted incidence rate) of less than six per 100,000 population. Proper treatments which these patients need cannot always be performed unless they find dedicated facilities. Patients tend to be desperate, searching for advice and care. Thus, they are called “cancer refugees”. Osteosarcoma and soft tissue sarcoma (OS/STS) are representative rare cancers in Japan. We conducted a retrospective analysis of patients with OS/STS to improve the current treatment modalities in a Japanese regional city. Patients and methods: Twenty-one patients with OS/STS who were hospitalized to receive standard chemotherapy or palliative treatment were enrolled between October 2011 and January 2017. Patients with non-Hodgkin’s lymphoma (NHL) and advanced cancer who were treated in the palliative care unit (PCU) of the Kawasaki Medical School General Medical Center were recruited as the control groups. We analyzed the difference in residential area between patients with OS/STS and the control groups. Results: Approximately one-third of patients with OS/STS were referred from hospitals outside of Okayama prefecture. The ratio of patients with OS/STS referred from Okayama city and/or the same medical administration area of Okayama prefecture was lower than that of patients with NHL and advanced cancer who were treated in the PCU. Conclusion: Because the medical environment of patients with OS/STS in Japanese local cities has not been consolidated, completing medical care within the patient’s own medical administration area is difficult. Thus, some patients with OS/STS may become “cancer refugees” who are unable to receive standard therapy near their residence. Keywords: osteosarcoma, soft tissue sarcoma, rare cancer, cancer refugee

Growth factors are commonly used to promote bone regeneration; however, the clinical impact is limited because the factors do not last long at a given site. The introduction of tissue engineering aimed to deter the diffusion of these factors is a promising therapeutic strategy. The purpose of the present study was to evaluate the in vivo osteogenic capability of an engineered bone morphogenetic protein-4 (BMP4) fusion protein. Methods: BMP4 was fused with a nanosized carrier, collagen-binding domain (CBD), derived from fibronectin. The stability of the CBD-BMP4 fusion protein was examined in vitro and in vivo. Osteogenic effects of CBD-BMP4 were evaluated by computer tomography after intramedullary injection without a collagen–sponge scaffold. Recombinant BMP-4, CBD, or vehicle were used as controls. Expressions of bone-related genes and growth factors were compared among the groups. Osteogenesis induced by CBD-BMP4, BMP4, and CBD was also assessed in a bone-defect model. Results: In vitro, CBD-BMP4 was retained in a collagen gel for at least 7 days while BMP4 alone was released within 3 hours. In vivo, CBD-BMP4 remained at the given site for at least 2 weeks, both with or without a collagen–sponge scaffold, while BMP4 disappeared from the site within 3 days after injection. CBD-BMP4 induced better bone formation than BMP4 did alone, CBD alone, and vehicle after the intramedullary injection into the mouse femur. Bone-related genes and growth factors were expressed at higher levels in CBD-BMP4-treated mice than in all other groups, including BMP4-treated mice. Finally, CBD-BMP4 potentiated more bone formation than did controls, including BMP4 alone, when applied to cranial bone defects without a collagen scaffold. Conclusion: Altogether, nanocarrier-CBD enhanced the retention of BMP4 in the bone, thereby promoting augmented osteogenic responses in the absence of a scaffold. These results suggest that CBD-BMP4 may be clinically useful in facilitating bone formation. Keywords: BMP4, bone repair, bone tissue engineering, osteogenesis

Abstract

The formation process of hexagonal boron nitride (hBN) monolayer sheets on single-crystalline ZrB2(0001) thin films grown on Si(111) wafers has been investigated by electron diffraction, scanning tunneling microscopy, and photoelectron spectroscopy. A two-step reaction was identified, resulting first in the formation of a silicon nitride layer by room temperature exposure of the silicene-terminated ZrB2 thin film surface to nitrogen radicals and then in the formation of an hBN monolayer replacing the silicon nitride layer through annealing at 900 °C. A large-scale moiré pattern and a clear dispersion of the π-electronic band provide evidence for the formation of an epitaxial hBN monolayer sheet directly on the diboride surface. The unique ability of the ZrB2(0001) surface, upon which both silicene and hBN monolayers can be formed, opens a way toward the integration of these two very different two-dimensional materials.
