AbstractThis study examined the differences in single and consecutive jumps on ground reaction forces (GRF) as well as metatarsophalangeal (MTP), ankle and knee kinematics and kinetics during jumping take‐off and landing. Eighteen basketball players performed countermovement jumps in both single and consecutive movement sessions. Synchronised force platform and motion capture systems were used to measure biomechanical variables during take‐off and landing. Paired t‐tests (or Wilcoxon signed‐rank tests) were performed to examine any significant differences regarding mean and coefficient of variation in each of the variables tested. A Holm–Bonferroni correction was applied to P‐values to control the false discovery rate of 5%. The findings indicated that consecutive jumps had lower jump height, take‐off velocity and landing impact. During take‐off, consecutive jumps demonstrated larger peak MTP and ankle extension velocities, knee extension moments as well as larger values for ankle and knee power generation; During landing, the consecutive jumps had larger peak MTP flexion angle, joint velocities (MTP, ankle and knee), and peak knee flexion moments and power absorption. Additionally, consecutive jumps had higher within‐trial reliability (i.e. smaller CV) for peak MTP flexion angle at landing (P < 0.05), but lower reliability (i.e. higher CV) for peak knee flexion velocity and power absorption at landing. These results suggest that the consecutive jump trials led to distinct movement kinematics and higher loading responses in jump take‐off and landing.

Abstract
High-temperature superconducting (HTS) maglev has great potential in the field of high-speed transportation due to its capability for passive stabilization. The levitation force between the bulk HTSs and the permanent magnet guideway is a significant parameter relating to operational safety and comfort. This force has an obvious hysteresis nonlinear characteristic, which can be represented by nonlinear stiffness and damping. The stiffness and the damping are functions of vertical displacement and velocity, respectively. The vibration velocity of a HTS maglev vehicle can at times exceed 100 mm s−1, but the existing levitation force test methods are almost quasi-static. These methods are unable to accurately measure the damping characteristic of the maglev system. In this paper, a viscoelasticity model is introduced to describe the dynamic force. The parameters in the model are identified using the least square method based on the vibration response of the HTS maglev system. Meanwhile, the effectiveness of the model and identification method are tested by numerical simulations. The hysteresis loops derived from the motion theory coincide with the practical ones. Finally, the method is applied to identify the parameters of hysteresis nonlinear levitation force in a previous experiment with dampers. Based on the established hysteretic model, the dynamic characteristics of the HTS maglev system can be well presented.
Delocalized information in quantum networks

Published: February 2020

Abstract
We consider entanglement-based quantum networks where information is stored in a delocalized way within regions or the whole network. This offers a natural protection against failure of network nodes, loss and decoherence, and has built-in security features. Quantum information is transmitted within the network by performing local measurements on individual nodes only. Information can be localized within regions or at a specific node by collaborative actions using only entanglement within a region, or sometimes even without entanglement. We discuss several examples based on error correction stabilizer codes, Dicke states and correlation space encodings. We show how to design fully functional networks using encoded states or correlation space resources.

Published: February 2020

Abstract
The Minister of Marine Affairs and Fisheries Regulation number 26/2014 has decreed that the distance between FADs should not be less than 10 nautical miles and should not be installed to make a fence effect. Highly dense FADs that are deployed with not enough distance between them in a certain period will change the movement pattern of tuna. This study aims to obtain information on the actual data of FADs deployed in the southern waters of East Java, to estimate the deployment area and to provide a recommendation on the ideal number of FADs deployed in these waters. The FAD deployment area has been estimated to be 219,792 km2 or 21,979,200 ha. Based on this estimation, it is calculated that the ideal number of FADs installed in these waters is 814 units. Estimates of the optimal number of tuna fishing units are carried out using linear goal programming (LGP) which suggests 380 units of sekoci (fishing vessel) as the optimal unit number that can operate annually at the Fishing Port of Pondokdadap, Malang Regency. The number of sekoci currently operating at this port is 644 units.

Abstract
Thresher sharks (family Alopiidae) are an evolutionarily distinct and globally endangered species group. Indonesia is the world’s largest shark fishing nation, and a global priority for reducing the capture of threatened shark species. Kutaradja port is one of Indonesia’s largest fishing ports, located in the capital of Aceh Province, Banda Aceh, Western Indonesia. Kutaradja is a large oceanic port serving a variety of fisheries, from small scale to industrial fleets. One of the main fisheries operating from Kutaradja port is an industrial purse seine fleet targeting valuable pelagic fish, particularly tuna. Pelagic sharks such as threshers are vulnerable to capture in these fisheries, due to their co-occurrence with stocks of valuable pelagic species. Here we describe the volume and composition of shark catch in Kutaradja’s purse seine fleet, based on daily landing monitoring conducted in January 2017 to May 2019. Our results show that the dominant species caught are thresher sharks (Alopiidae), which make up 51% of all shark landings. A total of 627 thresher sharks were landed during the monitoring period, consisting of 558 individuals of pelagic threshers shark (Alopias pelagicus) and 69 individuals of bigeye thresher shark (Alopias superciliosus). The catch is dominated by mature females, which could be particularly detrimental to the reproductive capacity of the population. Fishers in purse seine vessels often catch these threshers with hand-lines, which are used as a secondary gear while the main fishing gear is soaking. Based on these findings, we proposed recommendations for reducing thresher shark fishing mortality, including restricting the use of secondary fishing gears and releasing incidentally captured sharks.

Abstract
Managed access with reserved (MAR) is an approach for sustainable fisheries management, combined community-based conservation approach with spatial management to restore and protect Indonesia’s small-scale fisheries. This paper examines the implementation of MAR programs in Batu Belah village of Anambas islands marine recreational park, Riau islands province. The structured household survey and semi-structured interviews were conducted along with field observation during December 2018. The descriptive analysis applied to understand community knowledge, acceptance, participation, and perception on the current of marine environmental conditions, while the Analytic Network Process (ANP) used to identify problems and best strategies to improve future actions. Community knowledge and participation in MAR programs are at a moderate level, while community acceptance of MAR programs is at a high level. They mostly responded that the coastal environment is in better condition compared to previous years. Overall, the level of community perception in Batu Belah about the MAR program is in the moderate level category. There needs some improvement in terms of management capacity, creation of economic activities, and government budget allocation for monitoring and surveillance. Intensive community engagement and high commitment of leadership are among the key component to change community behavior and their paradigm regarding conservation perspective and coastal resources management in general.

AbstractScleractinian coral as the main builder of the reef contributes to building a complex reef framework through produce growing aragonite in their skeleton. In shallow water area (reef flat) the reef constructional process will be equal with erosional one, can be caused by mechanical damage such as storm or water motion and biological way (bioerosion). This research focused on the biological agent that influence on bioerosion process on massive Porites. 3 types of bioerosion they were grazing, boring, and etching. We monitored 10 massive Porites coral that was abundant at Pantai Kondang Merak, where each coral colony was segmented into 12 parts and then photographed to record data grazing and boring in massive Porites coral, while for etching was observed using Scanning Electron Microscopy (SEM). The result showed the number of bioerosion from grazing was 581 and boring was 1,155. The etching process was dominated by cyanobacteriaPlanobola macrogatathat live inside of coral skeleton. The grazing process caused by parrotfish and triggerfish, boring caused by polychaetes, bivalves, and sponge. Bioerosion process not only weakening reef structures but also increase habitat complexity of reef-associated biota and expand coral occupy in space with natural propagation.

AbstractScientist and environmentalist highlight the negative impact of a shrimp farm. The last decade analyzed numerous greenhouse gas emissions and aquaculture activities previously discussed. However, there are limited studies that reveal the emission of CO2and CH4related to aquaculture activities. The purpose of this study, therefore, is to examine the daily dynamics of these gases flux across the water-air interface of the shrimp ponds using a 3-day observation method and by examining the environmental factors responsible. This research was carried out in TIR Karawang shrimp farm area, with the gas samples were taken six times daily every 4 hours and analyzed using the gas chromatography. The results of this study show that in 24 hours, the minimum CO2emission (-0.15841+0.19220 mg m-2minute-1) found at 00.00 – 02.00 local time, and the maximum (0.22544+0.18361 mg m-2minute-1) at 12.00-14.00 local time. Conversely, the minimum CH4emission (-0.00024+0.00023 mg m-2minute-1) was at 00.00-02.00 local time and the maximum (0.00023+0.00017 mg m-2minute-1) at 12.00-14.00 local time. The dominant environmental factor influencing both gas is temperature. The semi-intensive shrimp farm CO2-e calculated is 0.02707 g C m-2day-1, for 2,500 m2ponds within a 110-day of culture, with 7.44545 kg C emitted.

Authors: Sumesh K R , Kanthavel K 
Published: February 2020

Abstract
This research was based on influence of various fly ash filler content in the machining properties of Pineapple (P)/Sisal (S) hybrid fiber reinforcement composites. Fly ash from bio waste materials of Bagasse (BGFA), Banana (BFA) and Coir (CFA) were used. High hardness nature of 3% BFA (22.73 HV) and 3% CFA (23.85 HV) reduces Material Removal Rate (MRR) and increases its surface roughness nature of the composites. Maximum MRR of 376.38 mm3 min−1 was observed in 3% BGFA combinations with 250 MPa Water jet Pressure (WP), 1mm Standoff Distance (SOD) and 20 mm min−1Traverse Speed (TS) as machining parameters. MRR of 353.64 and 352.76 mm3 min−1 was found out with 1% CFA and 1% BFA combinations. Lower surface roughness of 6.39 μm, 6.71 μm and 6.75 μm was found in 3% BGFA, 1% CFA and 1% BFA based composites. Filler surface created a tight bonding with the matrix, which reduces the erosion of fiber particles at higher WP. Untreated fibers showed lesser machining properties due to low fiber/matrix bonding. SEM results showed reducing of cracks and matrix breakages by the substitution of filler powders.

Published: February 2020

AbstractIn this work TiO2, Holmium doped (Ho-TiO2) Titanium oxide nanoparticles (NPs) and the corresponding nanostructured combinations (Ho-TiO2/ZnO NC) were successfully synthesized through sol gel method and reflux techniques respectively. The prepared nano materials were characterized with the help of x-ray diffraction Analysis (XRD), UV–visible spectroscopy, Scanning Electron Microscopy (SEM), Energy dispersive x-ray Analysis (EDX) and Fourier Transform infrared spectroscopy (FT-IR). The absorption spectra of nano materials were used for band gaps calculation. The band gap of pure TiO2NPs was found to be 3.10 eV which was effectively tuned to 2.65 eV by the doping of Holmium at different concentrations. XRD patterns confirmed the crystalline nature and purity of the synthesized nano materials. Morphology and elemental composition of the material were investigated using SEM and EDX respectively. FTIR helped in detecting the functional groups and grafting of the dye on the surface of nanoparticles. The nano materials were used as Photo-anodes in dye sensitized solar cells (DSSC). Pyrocatechol Violet dye was used as a photo-sensitizer. P3HT (polymer), a hole conducting polymer, was employed as a solid state electrolyte. I–V measurements were used for characterization of fabricated solar cells. Ho-TiO2/ZnO nanomaterial photosensitized with Pyrocatechol violet dye gave the highest percentage efficiency of 1.51. Other characteristic parameters of the fabricated devices such as short circuit current (Jsc), open circuit voltage (Voc), maximum power point (Mpp) and fill factor were found to be 11.2 mA cm−2, 0.41 V, 1.55(mW cm−2) and 0.33 respectively.
Lattice dynamics of Pnma Sn(S1–xSex) solid solutions: energetics, phonon spectra and thermal transport
Authors: Skelton Jonathan M 
Published: February 2020

Abstract
Alloying is widely used as a means to fine-tune the properties of thermoelectric materials by reducing the lattice thermal conductivity. However, the effects of compositional variation on the lattice dynamics of alloy systems are not well understood, due in part to the difficulty of building realistic first-principles models of structurally-complex solid solutions. This work builds on our previous study of Sn

solid solutions (Gunn et al 2019 Chem. Mater.

Se
x
) system, which has been widely studied for potential thermoelectric applications. We find that the vibrational internal energy and entropy have a large quantitative impact on the mixing free energy and are likely to be particularly important in alloy systems with competing phases. The thermodynamically-averaged phonon dispersions and density of states curves show that alloying preserves the structure of the low-frequency bands of modes associated with the Sn sublattice but broadens the high-frequency chalcogen bands into a near-continuous spectrum at the 50/50 mixed composition. This results in a general reduction in the phonon mode group velocities and an increase in the number of energy-conserving scattering channels for heat-carrying low-frequency modes, which is consistent with the decrease in thermal conductivity observed in experimental measurements. Finally, we discuss some of the limitations of our first-principles modelling approach and propose methods to address these in future studies.
Camus and the absurd
Authors: Gloag Oliver 
Published: February 2020

Abstract
What is the absurd? ‘Camus and the absurd’ explains that the absurd is a feeling that comes out of experience. For Camus it was a near-death experience: the brutal onset of tuberculosis at the age of 17. The absurd convinced Camus that there is no meaning to life because it could be cut short at any moment. His first three major works, Caligula, The Stranger, and The Myth of Sisyphus, are described. They were about narrating the absurd experiences, and the sometime violent clashes between those awakened to the absurdity of life and those who choose to ignore it.
Rebel without a cause
Authors: Gloag Oliver 
Published: February 2020

Abstract
In the midst of the Second World War, Camus realized that he could not be indifferent to the Nazi occupation of France and thus the nihilism of his absurd was untenable. Camus was still firmly against all-explaining theories and systemic change, but he had to find a way to theorize and narrate his decision to join the resistance, which on many levels contradicted some of the central tenets of the absurd. ‘Rebel without a cause’ describes how Camus would drastically change his stance in his second trilogy of works—The Plague, The Just Assassins, and The Rebel—which are part of Camus’s cycle of revolt.
Camus and Sartre—the breaks that made them inseparable
Authors: Gloag Oliver 
Published: February 2020

Abstract
‘Camus and Sartre—the breaks that made them inseparable’ describes how Camus and Jean-Paul Sartre critically reviewed each other’s work and, despite some unfavourable comments, how they became firm friends when they eventually met in 1943. They mostly socialized and there were no long conversations about one another’s works. The point of divergence between Camus’s absurd and Sartre’s existentialism led to the writers’ first genuine row. The two men had another ongoing disagreement with respect to the question of political violence. In short, however, it was colonialism that was at the centre of the ongoing dispute between the two men.
Seasonally specific changes in migration phenology across 50 years in the Black-throated Blue Warbler
Authors: Covino Kristen M , Horton Kyle G , Morris Sara R 
Published: February 2020

Abstract
The availability of detailed information that encompasses the geographic range of a species, spans a long-term temporal range, and yields individual information (e.g., age and sex), is a principle challenge in ecology. To this end, the North American Bird Banding Laboratory maintains a unique and underutilized dataset that can be used to address core questions of phenological change in migratory birds. We used records from 1966 to 2015 to quantify how the timing of migration has shifted in a long-distance migrant, the Black-throated Blue Warbler (Setophaga caerulescens). Additionally, we examined age and sex differences in the timing of migratory movements. We observed that early spring migrants passed through sites ~1.1 days earlier per decade and the peak of spring migration also occurred earlier over the 50 yr of this study. Additionally, phenological change was more rapid with increasing latitude during peak spring migratory periods. During fall, the peak of migration stayed consistent across the 50 yr studied, but the migratory season showed protraction overall. During spring, males consistently migrated earlier than females and adults migrated earlier than young individuals. During fall, there was no difference in timing between males and females, but young birds migrated earlier than adults. Additionally, migration proceeded faster in spring compared with the fall. This study reveals differential strategies in migrant timing, across seasons, age groups, and by sex, and shows that en route adjustments across latitude may account for changes in migrant timing. This basic information about such a fundamental ecological process is crucial to our understanding of migration and we must utilize these unique data to appreciate critical shifts at relevant scales of migration.
Two-part joint model for a longitudinal semicontinuous marker and a terminal event with application to metastatic colorectal cancer data
Authors: Rustand Denis , Briollais Laurent , Tournigand Christophe , Rondeau Virginie 
Published: February 2020

SummaryJoint models for a longitudinal biomarker and a terminal event have gained interests for evaluating cancer clinical trials because the tumor evolution reflects directly the state of the disease. A biomarker characterizing the tumor size evolution over time can be highly informative for assessing treatment options and could be taken into account in addition to the survival time. The biomarker often has a semicontinuous distribution, i.e., it is zero inflated and right skewed. An appropriate model is needed for the longitudinal biomarker as well as an association structure with the survival outcome. In this article, we propose a joint model for a longitudinal semicontinuous biomarker and a survival time. The semicontinuous nature of the longitudinal biomarker is specified by a two-part model, which splits its distribution into a binary outcome (first part) represented by the positive versus zero values and a continuous outcome (second part) with the positive values only. Survival times are modeled with a proportional hazards model for which we propose three association structures with the biomarker. Our simulation studies show some bias can arise in the parameter estimates when the semicontinuous nature of the biomarker is ignored, assuming the true model is a two-part model. An application to advanced metastatic colorectal cancer data from the GERCOR study is performed where our two-part model is compared to one-part joint models. Our results show that treatment arm B (FOLFOX6/FOLFIRI) is associated to higher SLD values over time and its positive association with the terminal event leads to an increased risk of death compared to treatment arm A (FOLFIRI/FOLFOX6).
Relating Hippocratic and Christian Medical Ethics
Authors: Cavanaugh Tom A 
Published: February 2020

AbstractThis article articulates the Hippocratic medical ethic found in the Oath and the Christian medical ethic as exemplified in the parable of the Good Samaritan. It proposes that the Oath has a natural-law-based deontological character (as understood by Aquinas) that governs friendships of utility (as understood by Aristotle) between student and teacher and physician and patient. The article elaborates on the Samaritan’s conduct as exemplifying Christian agapeic-love. It contrasts agapeic-love with friendship-love, while noting that the Samaritan relies on friendship-love (as found between the Samaritan and the innkeeper) to realize agapeic-love towards the robbers’ victim. It concludes with noting that the grace-based Christian medical ethic perfects the nature-based Hippocratic ethic not by destroying it, but, rather, by employing it.
