Amazon deforestation drives malaria transmission, and malaria burden reduces forest clearing
Authors: MacDonald Andrew J. , Mordecai Erin A. 
Published: October 2019

Significance
Widespread human impacts on the environment are expected to harm human health, which may in turn alter our interactions with the environment. However, evidence for impacts of environmental changes on health, and for feedbacks between environmental change and health, remains locally specific and context dependent. Using a large, geospatial dataset encompassing the Brazilian Amazon rainforest across 13 y, we identify strong evidence for a feedback between deforestation and malaria: Deforestation significantly increases malaria transmission, while high malaria burden simultaneously reduces forest clearing. Our results put into broader context the contradictory effects of deforestation on malaria found in earlier studies and provide evidence useful to land use policy and public health interventions that provide win–win solutions for conservation and health.

Published: October 2019

Significance
Mouse studies demonstrating regression of p53-null tumors following reinstatement of functional p53 have fueled the development of p53 reactivating drugs. However, successful p53 reactivation responses have only been formally demonstrated in tumor models where p53 inactivation served as the initiating event. Our study provides the first proof-of-principle evidence that p53 inactivation at late stages of tumorigenesis can also generate a vulnerability to p53 reactivation. However, this is dependent on intact ARF function highlighting ARF as a potential biomarker for p53 reactivation responses in tumors with late-stage p53 inactivation. It furthermore suggests the use of Mdm2 inhibitors as ARF mimetics for sensitizing ARF-deficient tumors to p53-reactivating drugs.
Myeloid cells activate iNKT cells to produce IL-4 in the thymic medulla
Authors: Wang Haiguang , Breed Elise R. , Lee You Jeong , Qian Lily J. , Jameson Stephen C. , Hogquist Kristin A. 
Published: October 2019

Significance
T cells, essential components of the immune system, are developed in the thymus. Various effector cytokines are produced in the thymus in the steady state, which affect T cell development and tolerance. Interleukin-4 (IL-4) produced by a unique subset of lipid-specific invariant natural killer T (iNKT) cells (NKT2) in the steady state influences a series of immune events to alter thymic development. However, the underling mechanisms for this steady-state IL-4 production are not completely understood. In this study, we show that steady-state IL-4–producing NKT2 cells predominantly localize to the thymic medulla. Furthermore, this steady-state IL-4 production requires continuous T cell receptor (TCR) signaling in NKT2 cells majorly stimulated by thymic macrophages.
How much reading between the lines is there in online game playing?
Authors: Sakai Noboru 
Published: October 2019

Abstract
This paper discusses to what extent people can convey and understand intentions and messages in Monster Strike,
which has only one tool for intentional messaging – called ‘good job’ (GJ) – to send messages to other players, and it is,
therefore, interesting to analyze how players exchange ideas and infer each other’s communicative intentions using a limited means
of communication towards a common goal. This paper describes the significance of GJ first through an analysis of actual game
playing, with supplemental information from players’ discussion spaces on line. The communications encompass (1) the original
meaning (i.e., ‘good job’); (2) extended interpretations; and (3) an attention signal, with shared temporary and cumulative
knowledge of the game and the players’ own dispositions.
Microscopic Study of Domain Structure in Charge Density Wave States in 2H-TaS1.8Se0.2
Authors: Ohta S , Fujisawa Y , Demura S , Sakata H 
Published: October 2019

Abstract
Transition metal dichalcogenides 2H-TaS2 and 2H-TaSe2 show charge density wave (CDW) state and superconductivity. It has been reported that elemental substitution of chalcogenide suppresses the CDW and enhances superconductivity. However, how the CDW order is suppressed by the substitution has not been clarified yet. To clarify this, we performed real space observation of the CDW state in the commensurate phase of 2H-TaS1.8Se0.2 by scanning tunneling microscopy. The existence of domains separated by walls at which the phase of the CDW shifts was observed. The change in the electronic state on the domain boundaries in 2H-TaS1.8Se0.2 was not as drastic as that in 1T-Fe

Influence of focused-ion-beam microfabrication on superconducting transition in exfoliated thin films of layered superconductor NbSe2
Authors: Tomori Hikari , Hoshi Naoki , Inoue Dai , Kanda Akinobu 
Published: October 2019

Abstract
We have experimentally studied the influence of the focused ion beam (FIB) microfabrication on the superconducting properties of exfoliated thin films of layered superconductor NbSe2 through transport measurement. We observed significant decrease of the residual-resistance ratio (RRR), indicating the formation of defects by the FIB. Although clear superconducting transition was seen before the FIB microfabrication, after FIB it was blurred, and one sample exhibited insulating behavior. The possible origins of the changes in the superconducting properties are discussed.
New oxide diluted magnetic semiconductor La0.75Ca0.25Cu0.75Mn0.25SO with independent spin and charge doping by first -principle study

Published: October 2019

Abstract
Here we report the first-principle study of a bulk oxide diluted magnetic semiconductor (DMS) La0.75Ca0.25Cu0.75Mn0.25SO and its parent LaCuSO. As a wide band gap p-type oxide semiconductor, LaCuSO system satisfies all the conditions forecasted theoretically to be a room temperature DMS, which is important for formation of high temperature spintronic devices. Then we compare the band gap and optical properties (such as loss function, reflectivity, absorption, the real part and the imaginary part of dieletric function among LaCuSO, (La0.75Ca0.25) (Cu0.75Mn0.25)SO, (La0.75Ba0.25) (Ag0.75Mn0.25)SO and (Y0.75Sr0.25) (Cu0.75Mn0.25)SO. The results show that the band gap of LaCuSO system decreases most drastically with co-doped Ca and Mn (from 2.1eV to 1eV). As for the optical properties, both the position and intensity of the peaks changed most drastically, too. It illustrates that the energy band structure influences the optical properties.

Published: October 2019

AbstractThe competition between phase formation of BaF2and Ba(Fe1−xCox)2As2on CaF2single crystals has been analysed. Ba(Fe0.92Co0.08)2As2thin films have been deposited by pulsed laser deposition. X-ray diffraction, atomic force microscopy and scanning electron microscopy studies have revealed that the formation of secondary phases and misorientations as well as the growth modes of the Ba(Fe0.92Co0.08)2As2thin films strongly depend on the growth rate. At high growth rates, formation of BaF2is suppressed. The dependency of the Ba(Fe0.92Co0.08)2As2lattice parameters supports the idea of fluorine diffusion into the crystal structure upon suppression of BaF2formation similar as was proposed for FeSe1−xTexthin films on CaF2. Furthermore, a growth mode transition from a layer growth mechanism to a three-dimensional growth mode at high supersaturation has been found, suggesting similarities between the growth mechanism of iron-based superconductors and high-Tccuprate thin films.

Published: October 2019

Abstract
We have experimentally studied response of a superconductor NbSe2 flake to perpendicular magnetic fields using small tunnel junctions. The NbSe2 film (lateral size ∼ several μm, thickness ∼ 50 nm) was obtained using the mechanical exfoliation of a bulk crystal and was transfered on top of predefined Au electrodes, forming an Au/NbSe2/Au double SIN tunnel junction system. At 4.2 K, between the lower and upper critical fields (H

C1 and H

C2), the voltage of the Au/NbSe2/Au structure under constant current of 1 μA exhibited random-telegraph-noise-like fluctuations as a function of the magnetic field which was applied perpendicular to the NbSe2 flake. The origin of the voltage fluctuations is discussed.
High-Yield Fabrication of Ag Films by Reel-to-Reel Pulsed Laser Deposition System
Authors: Matsuzaka Jin , Tsuchiya Yuji , Ichino Yusuke , Yoshida Yutaka 
Published: October 2019

Abstract
Ag films are deposited on REBCO tapes as a stabilizing layer by a sputtering method in the most case. The sputtering deposition has a disadvantage of material cost for wasted Ag due to a low deposition yield, contrary to the pulsed laser deposition (PLD) method. Therefore, we developed Reel-to-Reel PLD system to fabricate Ag films on tapes with the high deposition yield. As results, the PLD method has a deposition rate up to 1 nm/s as the sputtering method. The electrical resistivity of the Ag film by the PLD method is 4.7 times higher than the sputtering method. The deposition yield of the PLD method is 13 times higher than the sputtering method. Finally, the Ag film was deposited on moving tapes by using the developed Reel-to-Reel PLD system with a uniform thickness.
Improvement of the trapped field of REBCO bulk activated by pulsed field magnetization with a large soft-iron yoke
Authors: Yokoyama K , Oka T 
Published: October 2019

Abstract
We study to increase the trapped magnetic field of a REBCO bulk magnet excited by pulsed field magnetization (PFM). In PFM, a soft-iron yoke is used to expose the bulk to the magnetic field for a long time. Although a small yoke 40 mm in diameter was used in our previous study, it was changed to a large yoke 64 mm in diameter in this paper. Accordingly, the pulse width was extended by 13%. When a GdBCO bulk 60 mm in diameter and 20 mm thick was magnetized by varying an amplitude of the applied field and temperature in a bulk magnet system using a two-stage GM-type refrigerator with a cooling capacity of 12 W at 20 K, the maximum trapped flux density reached 4.07 T on the center of the bulk surface and 2.56 T on the pole surface at 20 K. Moreover, the total magnetic flux was 3.28 mWb, which was about 13% larger than that of a small yoke. This result suggests that this method is useful in practice because the trapped field can be enhanced only by changing the soft-iron yoke.
Ginzburg-Landau theory for the operation principle of superconducting delay-line inductance detectors
Authors: Koyama T , Ishida T 
Published: October 2019

Abstract
Transmission of voltage pulses generated by local heating in a kinetic inductance detector made of a superconducting stripline is theoretically investigated on the basis of the TDGL equation. The effect of thermal diffusion is also incorporated into the electrodynamics of this system. We derive an equation that can describe the generation and transmission of voltage pulses in this detector. A pair of voltage pulses with opposite polarities are created when a spatiotemporal variation in the superconducting order parameter occurs in a small region of this superconducting stripline. We clarify the characteristic feature in the shape of the voltage pulse.

Abstract
We are developing a new type of the neutron imager based on a superconducting neutron detector. We previously succeeded in constructing and demonstrating neutron detection capability of a superconducting current-biased kinetic inductance detector (CB-KID). In order to improve the spatial resolution and detection efficiency, the characteristics of a superconducting neutron detector have been studied systematically in the present work. As an extension of studying the characteristics of neutron detector, we investigated temperature dependence of neutron signal such as propagation velocity and the signal amplitude as a function of time of flight (ToF) with temperature. We consider that it is important to understand the temperature dependence of the signal to improve the spatial resolution and detection efficiency of a superconducting neutron detector.

Published: October 2019

Abstract
This paper describes study on remote inspection technology for pipes by using magnetostriction-based ultrasonic guided wave and high temperature superconductor (HTS) superconducting quantum interference device (SQUID) gradiometer. Magnetized nickel plates were adhered on an aluminium pipe sample, in order to use them as magnetostriction-based guided wave transceivers. A pair of 10mm-wide nickel plate with different angle arrangement were used to transceive uniformly distributed guided waves at all angles. A field coil was wound around one set of the nickel plates as a transmitter, while the other was used as a receiver. T (0, 1) mode guided wave was generated on the pipe by supplying a burst sine wave current of one cycle at several tens kHz to the coil. Multipoint measurements of the T (0, 1) mode guided waves around the pipe’s circumference were carried out by setting the HTS-SQUID gradiometer above the receiver with lift-off of about 9 mm and rotating the pipe for 360 degrees. Signal of reflected wave from an artificial slit on the sample was well detected. We simulated the distribution of the guided wave propagating on the pipe with the slit using an ultrasonic simulator and compared the distribution with the experiment result. The guided wave signal distributions including the defect signal obtained by experiment and simulation agreed well.
Experimental investigation of the processes of degradation and transition to the normal state in CC-tapes under the action of current pulses
Authors: Osipov M , Pokrovskii S , Abin D , Anishenko I , Rudnev I 
Published: October 2019

Abstract
The study of the behaviour of CC tapes under the action of nonstationary current loads was conducted: a transition to the normal state was observed, as well as processes of CC-tape degradation. The obtained data make it possible to solve the problems associated with the creation of high-speed switching devices based on high-temperature superconductors, intended for functioning in superconducting energy storage devices, energy distribution and transmission systems, current limiters, and new types of transport. In addition to superconducting switches, pulsed current loads can occur in the mentioned above systems due to short-circuit conditions or other factors, and can lead to local heating of HTSC, especially if there is an inhomogenity in the critical current in the CC-tapes. In this work we present the results of a study of non-stationary processes second generation HTS tapes heating under the impulse current loads with amplitudes up to 2.2Ic (77K, self-field). Superconducting tapes with a copper protective layer were used as the samples. The I-V characteristics of the samples were measured under the action of current pulses during cooling in liquid nitrogen. Critical parameters (amplitude, rise time of the transport current) of the current pulses, leading to the degradation of the superconductor were obtained. local current carrying characteristics of CC-tapes investigated using Hall probe magnetometry. The features of the influence of local inhomogeneities in the distribution of the critical current of the tapes on the transition of the superconductor to the normal state are revealed.
Experimental and theoretical discussion on step-out characteristics of high temperature superconducting induction/synchronous motor
Authors: Nakamura T , Sekiguchi D 
Published: October 2019

Abstract
This paper presents experimental and theoretical results of step-out characteristics of a 20 kW class High Temperature Superconducting Induction/Synchronous Motor (HTS-ISM). A fabricated motor (3-phase, 8-pole, rotor windings: HTS, stator windings: Cu) is investigated, and its maximum quasi-synchronous output is 20 kW at line voltage of 400 V. The step out condition and its behaviour is investigated for different combinations of the input voltage and the drive frequency at 77 K (atmospheric liquid nitrogen). It is shown that tested results of torque versus primary current characteristics agree well with the theoretical expression by compensating with no-load currents. However, the corresponding step-out current differ each other when air-gap magnetic flux density, which is in proportion to (voltage/frequency), increases. Based on electromagnetic field analysis, it could be concluded the reason for the above discrepancy is the magnetic saturation of the iron core. Furthermore, step-out occurs at the phase angle of 45 degree regardless of which is whether or not the step-out current is affected by the above magnetic saturation. These results are really important for the consideration of stable rotation condition of the HTS-ISM.
Fundamental Study on Cancer Therapy by Blocking Newborn Blood Vessels Using a Rotating Magnetic Field
Authors: Kirimura Makoto , Akiyama Yoko 
Published: October 2019

Abstract
In this study, we examined a novel cancer therapy by blocking newborn blood vessels with ferromagnetic particles. In this treatment, we try to necrose cancer by accumulating and aggregating the ferromagnetic particles inside the newborn blood vessels. Practically, this method needs to accumulate the particles in the deep part of the body, so the use of superconducting solenoidal magnets is essential. In addition, a design of magnetic field for accumulating the particles selectively in newborn blood vessels is necessary. We designed a rotating magnetic field that can locally accumulate the particles within a spherical range of 10 mm in diameter, 200 mm away from a source of magnetic field. According to the result of experiment and particle trajectory calculation, it was found that the accumulation range of the ferromagnetic particles can be controlled by the rotation frequency of the rotating magnetic field.
Palm oil spills on the performance of non-palm plantations in Indonesia: an empirical analysis
Authors: Harianto  
Published: October 2019

Abstract
Rapid development of oil palm plantations is predicted to cause various problems, one of which is the conversion of land and the shift of non-palm oil businesses to palm oil businesses. This research is aimed at analyzing the impacts of palm oil industry, through the price of palm oil in the international market, to the area and production of non-oil palm plantations (rubber, cacao, and coffee). The study employed time series data from 1991 to 2015. An econometric model was built to connect variables that affect the area and the production level of non-palm plantation and use multiple regression methods to determine its effect. The results showed that the price of palm oil had a positive effect on the expansion of rubber, cocoa, and coffee plantations. The effect of the price of palm oil on the production of non-palm plantations also shows a positive direction. Thus, the development of oil palm plantations does not have a negative impact on the development of non-palm plantations. The policy implications of the results of this study are the need to utilize the positive impacts of development of the palm oil industry for the development of plantations in the broadest sense.
Replanting policy of Indonesian palm oil plantation in strengthening the implementation of sustainable development goals
Authors: Purba Jan Horas Veryady 
Published: October 2019

Abstract
Indonesia’s palm oil industry is one of the National strategic commodities. This industry is inclusive and has a very broad impact on Indonesia’s economic development, regional development, poverty alleviation, the country’s foreign exchange resources and attempted to help overcome Indonesia’s balance of payments deficit. Along with the end of the first 25 years of age in most of oil palm plantations in Indonesia, the replanting policy has become an important momentum, because it concerns the future of the Indonesian oil industry, then continued with the second milestone of the 2040s. With replanting, Indonesia also improves productivity and is followed by improvements in technical culture. Indonesian oil palm productivity is directed to reach the 35-26 scenario, which is the production of 35 tons of FFB per ha and 26 percent yield so that Indonesia’s palm productivity will shift from productivity levels of 4.4 tons of CPO per hectare to 9 tons of CPO per hectare. With this level of productivity, Indonesia’s CPO production will increase from 77.17 million tons in 2050 to 94.64 million tons. The purpose of this study is not merely to look at oil palm plantations from an economic standpoint because in a broader scope, oil palm plantations have four multifunction agriculture, namely green functions, blue functions, yellow functions, and white functions. The replanting policy of Indonesian palm oil also plays a role in strengthening Indonesia’s palm oil industry in the achievement of the Sustainable Development Goals, which includes the economic fields (8 SDGs), social fields (6 SDGs) and the environment (3 SDGs).
