Authors: Picone Simonetta , Mondì Vito , Di Palma Federico , Martini Ludovica , Paolillo Piermichele
Published: July 2019

Objective This report discusses the neurological involvement in respiratory syncytial virus (RSV) infection in neonates.

Study Design We present a case report of a 2-month-old infant affected by a bronchiolitis RSV-positive, with syndrome of inappropriate antidiuretic hormone secretion (SIADH) correlated seizure and encephalopathy.

Results RSV infection can be associated as a serious disease in newborns involving the central nervous system (CNS) and causing seizures or acute encephalopathy. RSV may be also responsible for SIADH and seizures associated with hyponatremia. The RSV related encephalopathy could be caused by different mechanisms, such as direct viral invasion of the CNS or by indirect mechanism mediated by inflammatory cytokines. In addition, it can be favored by severe hyponatremia and SIADH that can cause cerebral edema. Some studies highlight that this virus-related encephalopathy lead to sudden infant death syndrome.

Conclusion In presence of neurological involvement during RSV-infection must be taken in consideration to performing instrumental test to detect cerebral edema. In addiction could be useful to dose inflammatory cytokines, and to consider the immune-modulatory therapy.

Authors: Liu Yongfeng , Gao Jianhua , Pei Pucheng , Yao Shengzhuo , Wang Fang , Qin Hua
Published: July 2019

To examine the effects of the inlet temperature on a proton exchange membrane fuel cell (PEMFC), this study proposes a dynamic temperature (DT) model by considering the dynamic variation in temperature that influences the water content of the cell and its performance. A three-dimensional model featuring the geometry and nonconformal mesh of the PEMFC is first formulated. An experiment was then conducted featuring a 34-cm2 single-cell and test system. Following this, a simulation and another experiment were carried out at a working temperature of 333 K with 100% relative humidity (RH) at inlet temperatures of 316 K, 323 K, and 328 K (at 50%, 60%, and 80% RH, respectively). The contours, which included hydrogen in the channels and water in the membrane, were then described. The results show that the proposed DT model can more accurately predict the performance of the PEMFC than the FLUENT model. In particular, when the inlet temperature was 328 K (80% RH), the maximum relative difference between the DT model and FLUENT was 13.8% compared to the results of the experiment. The hydrogen content in the channels decreased and the water content in the membrane increased as the reaction continued. The proposed model provides a new means for studying the effects of dynamic temperature on the PEMFC.
Evidence for the AlZn-Oi defect-complex model for magnetron-sputtered aluminum-doped zinc oxide: A combined X-ray absorption near edge spectroscopy, X-ray diffraction and electronic transport study
Authors: Bikowski Andre , Zajac Dariusz A. , Vinnichenko Mykola , Ellmer Klaus
Published: July 2019

Al-doped ZnO and Zn1 − xMgxO films, deposited by magnetron sputtering at substrate temperatures from about 25 °C to 500 °C and exhibiting a strong variation of the carrier concentration, were investigated by X-ray absorption spectroscopy (XAS), analyzing the X-ray absorption near-edge structures. The near-order structure, derived from the X-ray absorption spectra, shows that the dopant Al was built-in onto Zn lattice sites, independently of the deposition temperature up to 450 °C. FEFF calculations confirm the lattice location of the dopant on zinc lattice sites. The formation of secondary (spinel) phases occurs only at deposition temperatures above 450 °C, more pronounced for the Zn1 − xMgxO:Al films. In contrast to the XAS measurements, the electrical parameters of the films—carrier concentration and Hall mobility—exhibit a strong dependence on the substrate temperature, with a variation of the electron concentration by a factor of 4.5 from 25 °C to about 300 °C. This shows that the XAS method is significantly less sensitive compared to electrical measurements for the characterization of electrically active dopant elements. This fact is tentatively explained by the formation of oxygen interstitial defects Oi during deposition, annealing out at low temperatures, and by the formation of defect complexes of dopant atoms with intrinsic lattice defects, like Al-Oi or Al-Mg-Oi, which induce the observed electrical effects but are not detectable by XAS methods.

Published: July 2019

We report experimental research on laser plasma interaction (LPI) conducted in Shenguang laser facilities during the past ten years. The research generally consists of three phases: (1) developing platforms for LPI research in mm-scale plasma with limited drive energy, where both gasbag and gas-filled hohlraum targets are tested; (2) studying the effects of beam-smoothing techniques, such as continuous phase plate and polarization smoothing, on the suppression of LPI; and (3) exploring the factors affecting LPI in integrated implosion experiments, which include the laser intensity, gas-fill pressure, size of the laser-entrance hole, and interplay between different beam cones. Results obtained in each phase will be presented and discussed in detail.
Surface roughness analysis of Cu films deposited on Si substrates: A molecular dynamic analysis
Authors: Chen Zhiqiang , Cao Yunqi , Tian Wenchao , Wang Yongkun
Published: July 2019

Cu is a promising material to replace Al and Au in integrated circuits and microscale devices because of its low electrical resistivity, high electromigration resistance, and low cost. However, surface roughness affects the contact resistance of these devices, especially when the device is on a microscale or nanoscale. This paper focuses on surface roughness analysis of Cu films deposited on Si substrates by molecular dynamic simulation based on the mechanism of physical vapor deposition. The effects of film thickness, deposition temperature, deposition interval, and reflow temperature on the surface roughness of Cu films are studied in detail. The simulation results show that the surface roughness can be improved by appropriate adjustments of these parameters. They also provide a foundation for further work on the deposition of Cu films on Si substrates.
A Pt/ITO/CeO2/Pt memristor with an analog, linear, symmetric, and long-term stable synaptic weight modulation
Authors: Kim Hyung Jun , Kim Minju , Beom Keonwon , Lee Hyerin , Kang Chi Jung , Yoon Tae-Sik
Published: July 2019

Analog synaptic weight modulation that is linear, symmetric, and exhibits long-term stability is demonstrated by the resistance changes in a Pt/indium-tin-oxide (ITO)/CeO2/Pt memristor. Distinct from a Pt/CeO2/Pt memristor without the ITO layer, which shows highly nonlinear and asymmetric resistance changes, the Pt/ITO/CeO2/Pt memristor exhibits linear and symmetric resistance changes in proportion to the number of voltage applications with opposite polarities for potentiation and depression behaviors. The Pt/CeO2/Pt memristor also displays high long-term stability of modulated synaptic weight over time, which originates from the ITO layer acting as a reservoir of oxygen ions drifted from the CeO2 layer to retain the resistance change. Comparison of the results for the Pt/CeO2/Pt and Pt/ITO/CeO2/Pt memristors confirms the role of ITO in the linearity, symmetry, and long-term stability of the resistance change in CeO2-based memristors for use as artificial synapses in neuromorphic systems.
Metafilm focusing incident plane waves for energy harvesting
Authors: Li Mei , Tang Ming-Chun , Xiao Shaoqiu , Xiong Han
Published: July 2019

An ultrathin, composite metafilm consisting of gradient-index TE- and TM-type metasurfaces for high power electromagnetic energy harvesting applications is demonstrated. The proposed metafilm possesses the sinusoidal index-modulation property, which can convert incident plane waves (PWs) into surface waves (SWs) that concentrate to the center with high intensity and could be harvested by a single rectifier. Without the requirement of the increasing number of rectifiers and feed networks as commonly utilized in array-type rectennas or metasurfaces, a feasible amount of harvested power can be achieved by simply enlarging the film dimensions, and thereby, high SW to DC conversion efficiency is guaranteed. The results show that the harvested power would be increased from 4.1 μW to 73 μW by enlarging the panel dimensions from that containing 19 × 19 cells to 81 × 81 cells.
Open quantum dynamics of a three-dimensional rotor calculated using a rotationally invariant system-bath Hamiltonian: Linear and two-dimensional rotational spectra
Authors: Iwamoto Yuki , Tanimura Yoshitaka
Published: July 2019

We consider a rotationally invariant system-bath (RISB) model in three-dimensional space that is described by a linear rigid rotor independently coupled to three harmonic-oscillator baths through functions of the rotor’s Euler angles. While this model has been developed to study the dielectric relaxation of a dipolar molecule in solvation as a problem of classical Debye relaxation, here we investigate it as a problem of open quantum dynamics. Specifically, the treatment presented here is carried out as an extension of a previous work [Y. Iwamoto and Y. Tanimura, J. Chem. Phys 149, 084110 (2018)], in which we studied a two-dimensional (2D) RISB model, to a three-dimensional (3D) RISB model. As in the 2D case, due to a difference in the energy discretization of the total Hamiltonian, the dynamics described by the 3D RISB model differ significantly from those described by the rotational Caldeira-Leggett model. To illustrate the characteristic features of the quantum 3D rotor system described by angular momentum and magnetic quantum numbers, we derive a quantum master equation (QME) and hierarchical equations of motion for the 3D RISB model in the high-temperature case. Using the QME, we compute linear and 2D rotational spectra defined by the linear and nonlinear response functions of the rotor dipole, respectively. The quantum transitions between the angular momentum states and magnetic states arising from polarized Stark fields as well as the system-bath interactions can be clearly observed in 2D rotational spectroscopy.
The impact of manganese substitution on the structure and properties of tetrahedrite
Authors: Guélou Gabin P. L. , Powell Anthony V. , Smith Ronald I. , Vaqueiro Paz
Published: July 2019

The crystal structure of the tetrahedrites Cu12 − xMnxSb4S13 (x = 0, 1) has been studied by powder neutron diffraction between room temperature and 773 K. At all temperatures investigated, manganese exclusively occupies tetrahedral sites, while the trigonal-planar sites contain only copper. In situ diffraction data confirm the stability of the tetrahedrite phase up to 773 K, with no evidence of copper mobility at elevated temperatures. Analysis of atomic displacement parameters indicates that there are low-energy vibrations associated with the trigonal-planar and the tetrahedral copper cations. The Einstein temperatures for the copper cations range between 79 and 91 K. Manganese substitution increases the electrical resistivity and the Seebeck coefficient, while the thermal conductivity is reduced. This results in a modest improvement in the thermoelectric figure of merit for Cu12MnSb4S13, which reaches ZT = 0.56 at 573 K.
Bursting of molten steel thick films in a steel plate illuminated by a high energy laser
Authors: Lanzerotti M. , Brakke K. , Allen K. , Hartke J.
Published: July 2019

The beauty, kinematics, and dynamics of thin liquid soap films under the influence of gravity have inspired experimental and theoretical investigations by scientists at least since the research of Plateau and Lord Rayleigh in the mid1800s. The wide-ranging interest in thin films may also be attributed in part to readily available, inexpensive ingredients as well as to the enjoyable nature of the interactive activity itself. While the creation of the films produces relatively long-lived persistent films, the violent destruction of the films follows a rupture that may occur spontaneously and can also be initiated by external forces. This paper presents thick liquid films of molten steel and discusses the fundamental nature of the behavior of vertical thick films under the influence of gravity. This paper presents observations of stable thick liquid films of molten steel with thicknesses of 1.5 mm, 1.8 mm, and 1.9 mm. We observe spontaneous bursting of vertical thick films in the presence of gravity, without any other external forces, with an initial horizontal speed of 0.68 m/s–0.9 m/s and a vertical acceleration of ∼(6 ± 1)g, with sudden hole enlargement, like soap film popping. Experimental measurements of the preburst films, following cooling to room temperature, show the presence of a three-dimensional dimple and bulge and fairly agree well with theoretical predictions of Surface Evolver, due to a liquid surface tension that is strong enough to resist the force of gravity.

Root traits are essential for optimising nutrient and water absorption and anchorage. However, changes in root traits and the contribution of root-to-shoot growth and development of soybean (Glycine max (L.) Merr.) across a century of breeding are poorly documented. In this study, we adopted a grafting technique, using 55 cultivars released in the three main soybean-production regions in China as rootstocks in a pot experiment and 24 cultivars from the Yellow-Huai-Hai Valley (YHH) region as rootstocks in a field experiment, with cv. Zigongdongdou as the common scion. Changes in soybean roots, including dry weight (DW) of roots, lateral root number (LRN) and taproot length (TRL), and their contribution to shoot development and biomass formation, including shoot DW, plant height and node number, were evaluated under optimal conditions in 2011. Aboveground traits declined with year of release in the YHH region and did not vary over time in the northern Heilongjiang province and mid-south Heilongjiang region except for shoot DW. The root traits root DW, LRN and TRL were similar over years of release in the pot and field experiments. The results suggest that the newer cultivars have lesser shoot growth and root capacity but the same amount of root growth as older cultivars. Root traits did not change during selection, suggesting that improvement in soybean root traits should be an aim in future breeding.
The rhetorical use of political metaphor before, during and after the presidency
Authors: Borčić Nikolina , Čulo Ivona
Published: July 2019

This paper examines the ways in which politicians, depending on their political position, employ political metaphors as a tool to create a public image. Therefore, the use of political metaphors is analyzed through the prism of synergies of political topics, rhetorical strategies of evaluation and the use of personification. The research has been conducted on the sample of political interviews with the former Croatian President Ivo Josipović in a weekly talk show Nedjeljom u dva (Two o’clock on Sunday), aired on Croatian Television’s first TV channel. The analysis was based on making a distinction between the political phases of the chosen politician (presidential candidate, elected president, former president and politician). The aim of the paper was to point out how the same politician used the same source domain in an interrelation with the topic and as support for different argument functions. The results suggest that differentiating between political roles enable a view on how this particular politician frames his political debate depending on his function and goals.
Knifed in the back
Authors: Fenton-Smith Ben
Published: July 2019

A politician’s first public address in the role of party leader is a crucial performative act, as it presents him/her with a rare opportunity to (re) negotiate his/her personal narrative and ‘brand’ before an attentive national audience. Metaphors play an important role in this discursive management of power transfer. The data for this paper comprises speeches given in the aftermath of political deposals in Australian federal politics in the past quarter century. Reasons for variations in the metaphors found therein are considered, including the influence of genre, function and ideology. Four metaphor scenarios are found to be recurrent: leadership as direction, leadership as conflict, leadership as foundation, and leadership as hard work. The significance of novel metaphors is also considered.
The use of sensorimotor-based concepts during and after presidential campaigns
Authors: Stroebel Liane
Published: July 2019

Sensorimotor-based concepts (SBCs), a variation of political metaphors, are frequently used in political discourse. The particular challenge with these kinds of metaphors is that for a long time they have kept a low profile. SBCs are basic level concepts and can be used, not only frequently, but also iteratively to convey a subliminal story line. The present paper seeks to call attention to SBCs and to the extent to which this subgroup of metaphors orchestrates a wide range of precise, persuasive functions, by discussing differences in their usage during the French and U.S. presidential campaigns; in particular, in the speeches of Emmanuel Macron and Donald Trump before and after their respective election.
Variations of metaphors in party manifestos about EU finality
Authors: Kovář Jan
Published: July 2019

The literature on party positions on European integration and the closely related literature on Euroscepticism rely largely, from a methodological point of view, on coding of election manifestos and expert surveys/judgments. This paper opts for a different approach to study party positions on European integration based on an analysis of variation of the metaphors used by political parties in the discourse about the EU political finality. On the basis of key conceptual metaphors used in the discourse on EU finality that are identified in the relevant literature as well as the corpus itself, we analyze Czech political parties’ election manifestos issued for the 2004, 2009 and 2014 European Parliament elections. The analysis is then connected to party positions on European integration.
Local vs. global scope of discourse markers
Authors: Crible Ludivine
Published: July 2019

This paper discusses the relevance and challenges
of a corpus-based investigation of the scope of discourse markers.
It builds on Lenk’s
(1998) distinction between local and global scope of
discourse markers and maps it with annotation variables available in
existing corpora. Given the interplay of syntactic and
semantic-pragmatic variables that a direct approach to scope
involves, it is argued that indirect and independent cues (namely
position of the marker, its degree of syntactic integration and
co-occurrence with pauses) offer a more reliable access to the
variation in scope. The analysis focuses on three pairs of discourse
markers (topic-shifting vs. topic-resuming, coordinating vs.
subordinating conjunctions, objective vs. subjective uses of
so) in a corpus of spoken English.
Subjectivity of English connectives
Authors: Andersson Marta
Published: July 2019

The current study sets out to investigate
naturally produced English causal relations from the point of view
of conceptual and linguistic features that contribute to their
intended interpretations as Volitional or Non-volitional
result. These features include two discourse
connectives: as a result and for this
reason and the extent of the overlap between the
semantic information they encode and the relation type they
mark.

The paper reports on a mixed-method approach
combining a corpus investigation of result in the British
National Corpus (BNC) and two opinion-asking experiments conducted
via the crowdsourcing marketplace – Amazon Mechanical Turk (AMT).
The findings demonstrate that despite their functional flexibility
across different causal categories, English resultative connectives
show tendencies significant to mark specific coherence relations. The converging
methodology proves that expert linguistic intuitions are shared by
ordinary language users and their notion of differences between
causal event types.
Task-based analysis and the Competition Model
Authors: MacWhinney Brian
Published: July 2019

This chapter examines relations between Peter Skehan’s task-based analysis of second language production (Skehan, 1998) and the Competition Model (MacWhinney, 2012, 2015b). Both of these approaches have a long history of development. However, until recently, there has been little interaction between these two perspectives. In this paper, I will suggest that there is more room for interaction than previously imagined, and I will illustrate ways in which the Competition Model can benefit from the important insights and methods Skehan has developed. In addition to these conceptual interactions, there are now important methodological interactions that are becoming possible through the development of the new FluencyBank system at .

Extracellular vesicles (EVs) in plasma are commonly identified by staining with antibodies and generic dyes, but the specificity of antibodies and dyes to stain EVs is often unknown. Previously, we showed that platelet‐depleted platelet concentrate contains two populations of particles >200 nm, one population with a refractive index (RI) < 1.42 that included the majority of EVs, and a second population with an RI > 1.42, which was thought to include lipoproteins. In this study, we investigated whether EVs can be distinguished from lipoproteins by the RI and whether the RI can be used to determine the specificity of antibodies and generic dyes used to stain plasma EVs. EVs and lipoproteins present in platelet‐depleted platelet concentrate were separated by density gradient centrifugation. The density fractions were analyzed by Western blot and transmission electron microscopy, the RI of particles was determined by Flow‐SR. The RI was used to evaluate the staining specificity of an antibody against platelet glycoprotein IIIa (CD61) and the commonly used generic dyes calcein AM, calcein violet, di‐8‐ANEPPS, and lactadherin in plasma. After density gradient centrifugation, EV‐enriched fractions (1.12 to 1.07 g/mL) contained the highest concentration of particles with an RI < 1.42, and the lipoprotein‐enriched fractions (1.04 to 1.03 g/mL) contained the highest concentration of particles with an RI > 1.42. Application of the RI showed that CD61‐APC had the highest staining specificity for EVs, followed by lactadherin and calcein violet. Di‐8‐ANEPPS stained mainly lipoproteins and calcein AM stained neither lipoproteins nor EVs. Taken together, the RI can be used to distinguish EVs and lipoproteins, and thus allows evaluation of the specificity of antibodies and generic dyes to stain EVs.
Adaptive ultrasound reflectometry for lubrication film thickness measurements
Authors: Kaeseler R L , Johansen P
Published: July 2019

Adaptive ultrasound reflectometry methods for lubrication film thickness measurements is of great use for condition monitoring and prognostics of systems which have high repair costs and are remotely located, such as off-shore systems, as they recursively calibrate the incident ultrasound wave. Typical manual calibration requires a constant incident wave over the life-cycle of the system, or until new manual calibration can be conducted. Auto-calibration accounts for the changes in the incident ultrasound wave caused by changing environmental conditions, occurring over longer periods of time. The vision of adaptive ultrasound reflectometry methods is therefore increased robustness of lubrication film thickness measurements in a range of applications. In this article an adaptive scheme is proposed. The scheme is based on a thin-layer time-of-flight method for thickness determination, and an extended Kalman filter for estimation of the incident wave spectrum. The adaptive scheme is experimentally tested, and the feasibility of the algorithm is established, but serious issues regarding the robustness and reliability of the method are revealed by a disturbance analysis. However, the experiments and a theoretical layer phase-lag sensitivity analysis reveal that the estimation of the incident wave phase is of high importance for layer thicknesses above

m, and for very thin layers below

m the estimation of the magnitude dominates the measurement accuracy. This entails that the research in adaptive schemes should be directed towards phase- or magnitude-tracking performance, depending on the working range of the layer thickness, such that sufficient robustness and reliability of the algorithms can be assured.
An in situ characterization technique for electron emission behavior under a photo-electric-common-excitation field: study on the vertical few-layer graphene individuals

Published: July 2019

The in situ characterization on the individuals offers an effective way to explore the dynamic behaviors and underlying physics of materials at the nanoscale, and this is of benefit for actual applications. In the field of vacuum micro-nano electronics, the existing in situ techniques can obtain the material information such as structure, morphology and composition in the process of electron emission driven by a single source of excitation. However, the relevant process and mechanism become more complicated when two or more excitation sources are commonly acted on the emitters. In this paper, we present an in situ nano characterization technique to trigger and record the electron emission behavior under the photo-electric-common-excitation multiple physical fields. Specifically, we probed into the in situ electron emission from an individual vertical few-layer graphene (vFLG) emitter under a laser-plus-electrostatic driving field. Electrons were driven out from the vFLG’s emission edge, operated in situ under an external electrostatic field coupled with a 785 nm continuous-wave laser-triggered optical field. The incident light has been demonstrated to significantly improve the electron emission properties of graphene, which were recorded as an obvious decrease of the turn-on voltage, a higher emission current by factor of 35, as well as a photo-response on-off ratio as high as 5. More importantly, during their actual electron emission process, a series of in situ characterizations such as SEM observation and Raman spectra were used to study the structure, composition and even real-time Raman frequency changes of the emitters. These information can further reveal the key factors for the electron emission properties, such as field enhancement, work function and real-time surface temperature. Thereafter, the emission mechanism of vFLG in this study has been semi-quantitatively demonstrated to be the two concurrent processes of photon-assisted thermal enhanced field emission and photo field emission.
Highlights of the production of (anti-)(hyper-)nuclei and exotica with ALICE at the LHC
Authors: Dönigus Benjamin
Published: July 2019

Measurements of the production of light (anti-)nuclei and (anti-)hypernuclei have been performed in different colliding systems at the LHC, namely pp, p–Pb and Pb–Pb. The results of the production in Pb–Pb collisions of light (anti-)(hyper-)nuclei follows the expectation of the thermal model, whereas the production of nuclei in pp and p–Pb collisions shows a closer agreement with the expectations from coalescence models. Both models can give predictions for the production yields of hypothetical states such as bound states of two Λ hyperons or of a Λ and a neutron, which are expected to decay weakly. These states are searched for with the ALICE apparatus. Since no signal is found, upper limits, which are significantly below the model expectations, are set. Furthermore, the most recent measurement of the lifetime of the hypertriton determined in Pb–Pb collisions at

The Large Hadron Collider (LHC) has been successfully delivering proton-proton collision data at the unprecedented center of mass energy of 13 TeV. An upgrade is planned to increase the instantaneous luminosity delivered by the LHC in what is called HL-LHC, aiming to deliver a total of about 3000 fb

of data per experiment. To cope with the expected data-taking conditions ATLAS and CMS are planning major upgrades of the detectors. Additionally, ATLAS and CMS are preparing inputs to a CERN Yellow Report that aims to summarize the physics reach for HL-LHC and will be submitted as input to the European Strategy before the end of 2018. This contribution focusses on the physics reach expected for a wide range of measurements and searches at the HL-LHC for the ATLAS and CMS experiments, including Higgs coupling, di-Higgs boson production sensitivity, Vector Boson Scattering prospects as well as discovery potential for electroweak SUSY and other exotic benchmark scenarios.

In a revolutionary paper, Matsui and Satz proposed using the suppression of quarkonia as a smoking gun signature of deconfinement in relativistic heavy ion collisions. The stunning success of using strong-coupling, AdS/CFT techniques to predict the viscosity to entropy density ratio extracted from RHIC and LHC heavy ion collision data using sophisticated 3+1D relativistic viscous hydrodynamics has prompted further investigation into the physics of a strongly-coupled plasma. We compute, for the first time, the suppression of bottomonia in a strongly coupled QGP, and compare the results to those from a weakly coupled QGP and to data. The complex binding energies which inform the thermal width and hence the RAA

Phase transitions in finite size systems
Authors: Mogliacci Sylvain , Kolbé Isobel , Horowitz W A
Published: July 2019

We follow recent developments of a finite size thermal field theoretic formalism, which is mainly relevant to the investigation of small size corrections to the thermodynamical properties of the quark-gluon plasma. In doing so, we rely on statistical mechanics and large deviation theory arguments, and investigate geometrically confined systems of infinite volume V with a finite spatial extent L. More specifically, we focus on systems in contact with a heat bath as well as on isolated ones. We find and present in detail the characteristic behaviors of a first and a second order phase transition, respectively. In the former case, we establish a connection between the phase transition and the mechanical support of the system. In the latter one, we identify a critical length L
c~(V/EL)1/3, where E is the total energy of the system which is fixed. We also briefly comment on the relevance of our findings, for respectively both the Casimir experiments and the future quark-gluon plasma phenomenology.
The Implementation Of Collaborative Governance In Segoro Amarto Social Movement In Yogyakarta City
Authors: Fitriana K.N. , Satlita L. , Winarni F.
Published: July 2019

Colloborative governance increasingly involves a major role in implementing major policy drives in localities. Understanding how the stakeholders may provide value is therefore essential to understanding collaborative governance practically. This research aims to analyzing the goal impact of collaborative governance in the implementation of “Segoro Amarto’ as a social movement to poverty alleviation in Yogyakarta. A qualitative descriptive approach is used to explore data about the role between actors, the collaborative process carried out, and the goals achievements of collaborative governance in segoro amarto. The measurement of the goals achievement of Segoro Amarto uses indicators as follows: the type of network structure, commitment to the goals, trust between stakeholders, governance, access to authority, accountability and responsibility, information delivery, and access to resources. However, the results of collaborative governance in the implementation of the Segoro Amarto movement in Yogyakarta City have not yet represented the construction of integrative and holistic collaboration between actors because there is still a dominance of the role of the government and the dependence on the government in implementing poverty alleviation programs from the Segoro Amarto Movement. The implementation of the Segoro Amarto movement adopted top down policy from the Yogyakarta Government, so that efforts to empower the community tend to be only in the form of implementing partial governments programs. The involvement of the private sector and non-governmental organizations has not been fully involved. The Good results are found in aspects of commitment to goals, trust between actors, delivery of information, accountability and resposibility. Whereas, the results that are still not good are found in the aspects of network structure, access to authority, access to resources and governance. The failrure to achieve the results of collaborative governance in the Segoro Amarto implementation can be influenced by the dynamics of the problems which include: (1) There are differences in understanding, character and mindset of the implementing actors and the community, (2) the lack of moral will and political will in a holistic way to build awareness of each actor in strengthening social capital, (3) The culture of the community to depend on government assistance and the habit of receiving assistance in the form of money from the government to the community hampers the process of empowering the community, (4) Authority in decision making and budget allocations that are too tiered thus hampering in the process of implementing Segoro Amarto.

Learned from the 2010 eruption, mitigation action was developed by preparing more and adequate evacuation shelters. During period of staying in evacuation shelter, primary necessity of clean water for the refugees needed to be fulfilled. Groundwater was considerated to be the alternative source to fulfill the needs of clean water for the refugeess in evacuation shelters. However, the amount of groundwater sources on the area of evacuation shelter had to be able to meet the domestic water necessity of all refugeess. This research aimed to measure the potential’s amount of groundwater on the surrounding area of evacuation shelter, particularly in Cangkringan district, and to identify the capability of groundwater to fulfill the refugees’s domestic water necessity in the evacuation shelter in Cangkringan district. Dynamic groundwater discharge method by Darcy model was used to measure the prediction of potential groundwater. The result showed potential of groundwater in Cangkringan were as much 88,417.2 m3/day or 88,417.200 liter/day. Total water necessity of refugees in Cangkringan was 335,700 liters/day. Compared to the prediction value of groundwater potential, the total water necessity of refugees in Cangkringan was able to be fulfilled.

The study of antibacterial activity of oil from Tamarindus indica Linn seed and fatty acids was conducted in this research. Oil of this plant seed was isolated by extraction and fractionation. Constituents of fatty acid in the oil identified as methyl ester fatty acids. The methyl ester fatty acid was carried out by trans-esterification with methanol/BF3. The methyl ester was identified by gas chromatography and mass spectrometer (GC-MS). There are 13 fatty acids in the Tamarindus indica seed oil including octanoic, decanoic, dodecanoic, tetradecanoic, hexadecanoic, octadecanoic, eicosanoic, docosanoic, tetracosanoic, 11-octadecenoic, 11-eicosenoic, 9,12-octadecadienoic, and 9-octadecenoic acids. The transformation of tamarind seed oil into fatty acids was carried out through hydrolysis with potassium hydroxide solution followed by acidification with a hydrochloric acid solution. The physical and biological properties of the seed oil and fatty acids against antibacterial activity are reported in this paper.

Oil palm fruit fiber (mesocarp) is waste generated mainly from palm oil manufacturing activities. Since it is organic in origin, they are rich in nutrient for the plant. Composting can be a suitable method for converting the fiber into compost that can be used as growing media. In this study, three types of composts were made by mixing the fiber with cow manure in ratios as follows: fiber compost I (3:1), fiber compost II (1:1) and fiber compost III (1:3) respectively and the chemical properties (pH, temperature and nutrient content) of them were determined. Their suitability as growing media was observed through growth performance of oil palm seedlings. They were grown in four types of growing media which were F0 = subsoil 100% (control), F1 = 90% fiber compost I : 10% subsoil, F2 = 90% fiber compost II : 10% subsoil, F3 = 90% fiber compost III : 10% subsoil. As results, initial pH of fiber compost I were lower than other composts but value eventually similar by the end of the study. The composting temperature which higher, in the beginning, were decreasing and were stable at the end of composting (week 6). The growth of oil palm seedlings was the greatest when grown in a mixture of 90% fiber compost II: 10% subsoil. Results of this study suggest a bright future for the use of fiber as growing media as indicated in chemical properties of fiber that can be improved through composting process and its positive effect as reflected in the growth of oil palm seedlings.

Zelenkov et al. [1] proposed a two-step classification method (TSCM) based on genetic algorithm to predict the bankruptcy of Russian companies. This current study was conducted to do more comprehensive evaluation than Zelenkov et al. [1] did. We involved more datasets, compared to a greater number of competitive methods, and developed the ensemble using more base classifiers. The datasets consisted of nine datasets and then the result of prediction compared to previous studies from 13 papers that were published between 1996 and 2009. In addition, the previous method using five base classifiers, this study involved seven base classifiers. The purpose of this study is to compare the accuracy of prediction from previous studies with this method. In this study, we used k-Nearest Neighbour (k-NN), Logistic Regression (LR), Naïve Bayes (NB), Decision Tree (DT), support vector machine (SVM), random forest (RF), and boosting as the base classifiers of ensemble model. Genetic algorithm is used to find the best predictor variables and the best weight for each base classifier. The result of TSCM shows that the accuracy of prediction can increase about 0-34% for some datasets compared to the previous studies.

In Data Science, we usually encounter High-dimensional data. In this situation, the Classical Regression method usually cannot perform well because it is impossible to include all covariates in the model since the number of a parameter to be estimated is larger than the sample size. Least absolute shrinkage and selection operator (Lasso) method is one of the methods which can deal with this problem. Lasso regression perform the selection of covariates so that only the most influential covariates are used in the model. Unfortunately, most of Lasso method should be performed in CLI Software which is difficult to use for the general user. For this reason, we develop a web application by using Shiny to perform the Lasso method based on GUI which is easier to use. It allows users to analyze high-dimensional data without using programming language. The paper contains an implementation of Lasso Regression using web application on olive pomade oil data.

Antioxidant properties of clove bud have been widely studied due to its potential use in the pharmaceuticals field. One of the chemical bioactive compounds that show antioxidant activity is flavonoid. Our study revealed that the flavonoid content of ethanol-derived extract of clove bud was approximately 93.245 mg QE/100 gram. Less is known regarding the mode of actions of antioxidant from clove bud in cellular systems. In this study, we used model organism yeast Saccharomyces cerevisiae to study the action of antioxidant activity in cellular systems. We found that ethanol-derived clove bud extract (100 ppm) enhanced cells viability following H2O2-induced oxidative stress. Interestingly, clove bud extract increased yeast-antioxidative stress tolerance phenotype in a dose-independent manner. Suggesting, prooxidant activity of clove bud extract. Mitochondria have been known to involve in oxidative stress tolerance mechanisms primarily via mitochondrial adaptive ROS-signaling. Our data revealed that yeast mitochondrial membrane potential was unchanged following 100 ppm extract treatment yet significantly increased in higher extract treatment. Our study indicated that 100 ppm extract-supplementation in yeast culture resulted in a higher survival rate of yeast after 15-days of incubation, compared to that without extract treatments. We suggest that clove bud extract (100 ppm) could enhance oxidative stress tolerance phenotype in yeast S. cerevisiae, which then attributed on life span extension through its ROS scavenging activity. Further study must be conducted to confirm the underlying mechanisms of clove bud extract both physiologically and genetically.
