description: Dissolved silicon (dSi) is a key nutrient in the oceans, but data regarding Si isotopes in coastal aquifers are not widely available. Here we investigate the Si isotopic composition of 12 fresh and 16 saline groundwater samples from Rottnest Island, Western Australia, which forms part of the world's most extensive aeolianite deposit (the Tamala Limestone formation). In total, two bedrock samples were also collected from Rottnest Island for Si isotope analysis. The δ30Si values of groundwater samples ranged from −0.4 ‰ to +3.6 ‰ with an average +1.6 ‰, and the rock samples were −0.8 ‰ and −0.1 ‰. The increase in δ30Si values in fresh groundwater is attributed to the removal of the lighter Si isotopes into secondary minerals and potentially also adsorption onto Fe (oxy)hydroxides. The positive correlations between δ30Si values and dSi concentrations (ρ = 0.59; p = 0.02) and δ30Si values and Cl, but not dSi and Cl concentrations, are consistent with vertical mixing between the younger fresh groundwater and the deeper groundwater, which have undergone a greater degree of water–rock interactions. This has produced a spatial pattern in δ30Si across the aquifer due to the local hydrogeology, resulting in a correlation between δ30Si and tritium activities when considering all groundwater types (ρ = −0.68; p = 0.0002). In the deeper aquifer, the inverse correlation between dSi and Cl concentrations (ρ = −0.79; p = 0.04) for the more saline groundwater is attributed to groundwater mixing with local seawater that is depleted in dSi (< 3.6 µM). Our results from this well-constrained island aquifer system demonstrate that stable Si isotopes usefully reflect the degree of water–aquifer interactions, which is related to groundwater residence time and local hydrogeology. Our finding that lithogenic Si dissolution occurs in the freshwater lens and the freshwater–seawater transition zone on Rottnest Island appears to supports the recent inclusion of a marine–submarine groundwater discharge term in the global dSi mass balance. Geologically young carbonate aquifers, such as Rottnest Island, may be an important source of dSi in coastal regions with low riverine input and low oceanic dSi concentrations.

description: In some settings involving recurrent events, the occurrence of one event may produce a temporary increase in the event intensity; we refer to this phenomenon as a transient carryover effect. This paper provides models and tests for carryover effect. Motivation for our work comes from events associated with chronic health conditions, and we consider two studies involving asthma attacks in children in some detail. We consider how carryover effects can be modeled and assessed, and note some difficulties in the context of heterogeneous groups of individuals. We give a simple intuitive test for no carryover effect and examine its properties. In addition, we demonstrate the need for detailed modeling in trying to deconstruct the dynamics of recurrent events.

description: We report on a variety of continuous wave and pulsed laser sources based on Thulium- and Holmium-doped materials, emitting in the spectral range around 2 μm. This includes continuous wave Thulium-doped fiber lasers which have been realized based on the beam combining technique by using tapered fused bundles and truly single mode WDM cascades, respectively. A pulsed laser source emitting nano- or picosecond pulses has been developed in a master oscillator power amplifier (MOPA) configuration, which consists of a gain-switched diode operating at a wavelength of 1.95 μm, followed by Thulium-doped fiber-based pre- and main amplifiers. Furthermore, we present a femtosecond regenerative amplifier system using Thulium:YAP and Holmium:YAG crystals with emission wavelengths around 1.95 μm and 2.1 μm, respectively. Output energies of more than 700 μJ have been generated with both systems.

description: This study was conducted to evaluate the effect of supplementing leaves of desert date (Balanites aegyptiaca), maize grain and their mixture on growth performance and economic return of indigenous goats fed on a basal diet of natural pasture hay. Twenty intact indigenous goats with ages 8-10-months and an average initial body weight of 16.13±1.17kg (Mean± SD) were used in the study. The experimental animals were acquired from volunteer goat producers at Fetele Doronje kebele, Mirab Abaya district of Gamo Zone, southern Ethiopia. The animals were blocked into five blocks with a block containing four kids. The kids were randomly assigned to one of the four treatments within a block allowing five bucks per treatment feeds. Dietary treatments consisted of feeding natural pasture hay ad libitum (T1); natural pasture hay ad libitum supplemented with 200g maize grain (T2); natural pasture hay ad libitum supplemented with 200g dried leaves of desert date (T3), and natural pasture hay ad libitum supplemented with mixture of 200g of dried leaves of desert date and maize grain at 1:1 ratio (T4) on dry matter (DM) basis. 50 g wheat bran was added to all animals to satisfy the maintenance requirement of the control group. The total DM intake in the current study was higher (p<0.001) for the supplemented group than the control ones. The result showed that supplementing goats with maize grain, desert date and their mixture (T2-T4) attained ADG of 48.7, 48.9 and 66.8g/day for T2, T3 and T4, respectively as compared to the control (33.2g/day). However, among the supplemented groups, goats fed on T4 diet gained superior (p<0.001) ADG than goats fed on T2 and T3 diets. Moreover, supplementing indigenous goats with desert date, maize grain and their mixture relatively improved the return compared to the control group. The partial budget analysis further revealed that T4 was more profitable as compared to other supplementary treatments. Therefore, supplementing growing goat kids with T4 could be recommended to smallholder goat producers in the study area for better animal performance and profitability.

description: As renewable lignin building blocks, hydroxystyrenes are particularly appealing as either a replacement or addition to styrene-based polymer chemistry. These monomers are obtained by decarboxylation of phenolic acids and often subjected to chemical modifications of their phenolic hydroxy groups to improve polymerization behaviour. Despite efforts, a simple, scalable, and purely (chemo)catalytic synthesis of acetylated hydroxystyrenes remains elusive. We thus propose a custom-made chemoenzymatic route that utilizes a phenolic acid decarboxylase (PAD). Our process development strategy encompasses a computational solvent assessment informing about solubilities and viable reactor operation modes, experimental solvent screening, cascade engineering, heterogenization of biocatalyst, tailoring of acetylation conditions, and reaction upscale in a rotating bed reactor. By this means, we established a clean one-pot two-step process that uses the renewable solvent CPME, bio-based phenolic acid educts and reusable immobilised PAD. The overall chemoenzymatic reaction cascade was demonstrated on a 1 L scale to yield 18.3 g 4-acetoxy-3-methoxystyrene in 96% isolated yield. © 2022 The Royal Society of Chemistry.

description: This paper covers a numerical analysis of a novel approach to increasing the crashworthiness of double hull ships. As proposed in Schöttelndreyer (Füllstoffe in der Konstruktion: ein Konzept zur Verstärkung vonSchiffsseitenhüllen, Technische Uni-versitt Hamburg, Hamburg, 2015), it involves the usage of granular materials in the cavity of the double hull ship. For the modeling of this problem, the discrete element method (DEM) is used for the granules while the finite element method is used for the ship’s structure. In order to account for the structural damage caused by collision, a gradient-enhanced ductile damage model is implemented. In addition to avoid locking, an enhanced strain-based formulation is used. For large-scale problems such as the one in the current study, modeling of all granules with realistic size can be computationally expensive. A two-scale model based on the work of Wellmann and Wriggers (Comput Methods Appl Mech Eng 205:46–58, 2012) is applied—and the region of significant localization is modeled with the DEM, while a continuum model is used for the other regions. The coupling of both discretization schemes is based on the Arlequin method. Numerical homogenization is used to estimate the material parameters of the continuum region with the granules. This involves the usage of meshless interpolation functions for the projection of particle displacement and stress onto a background mesh. Later, the volume-averaged stress and strain within the representative volume element is used to estimate the material parameters. At the end, the results from the combined numerical model are compared with the results from the experiments given in Woitzik and Düster (Ships Offshore Struct 1–12, 2020). This validates both the accuracy of the numerical model and the proposed idea of increasing the crashworthiness of double hull vessels with the granular materials. © 2021, The Author(s).

description: The application of newly developed first-principle modeling techniques to liquid water deepens our understanding of the microscopic origins of its unusual macroscopic properties and behaviour. Here, we review two novel ab initio computational methods: second-generation Car-Parrinello molecular dynamics and decomposition analysis based on absolutely localized molecular orbitals. We show that these two methods in combination not only enable ab initio molecular dynamics simulations on previously inaccessible time and length scales, but also provide unprecedented insights into the nature of hydrogen bonding between water molecules. We discuss recent applications of these methods to water clusters and bulk water.

description: Deep cryogenic treatment of tool steels, incorporated in conventional hardening and tempering, has been a topic of intensive research in recent years. Yet, the governing microstructural mechanisms involved in the deep cryogenic treatment of high-alloyed tool steels are still controversial. Thus, an in situ X-ray diffraction study is conducted on three tool steels X38CrMoV5-3, X153CrMoV12, and ~X190CrVMo20-4 to shed light on microstructural evolution during cryogenic treatment and subsequent tempering. For these high-alloyed tool steels, the transformation of retained austenite into martensite is detected during the cooling phase of the cryogenic treatment. A change in tetragonality of martensite occurs mainly in the heating phase of the subsequent tempering process, which indicates the diffusion of carbon and carbide precipitation from the martensite. The microstructure evolution of the tool steels after hardening, cryogenic treatment, and tempering is further examined by scanning electron microscopy. © 2021 The Authors.

description: The correlated electron system SmNiO3 exhibits a metal-insulator phase transition at 130 °C. Using an ionic liquid as an electric double layer (EDL) gate on three-terminal ultrathin SmNiO3 devices, we investigate gate control of the channel resistance and transition temperature. Resistance reduction is observed across both insulating and metallic phases with ~25% modulation at room temperature. We show that resistance modulation is predominantly due to electrostatic charge accumulation and not electrochemical doping by control experiments in inert and air en-vironments. We model the resistance behavior and estimate the accumulated sheet density (~1-2 x 10^14 cm^-2) and EDL capacitance (~12 μF/cm^2).

description: Radical ontic structural realism (ROSR) asserts an ontological commitment to 'free-standing' physical structures understood solely in terms of fundamental relations, without any recourse to relata which stand in these relations. Bain (2011) has recently defended ROSR against the common charge of incoherence by arguing that a reformulation of fundamental physical theories in category-theoretic terms (rather than the usual set-theoretic ones) offers a coherent and precise articulation of the commitments accepted by ROSR. In this essay, we argue that category theory does not offer a more hospitable environment to ROSR than set theory. We also show that the application of category-theoretic tools to topological quantum field theory and to algebraic generalisations of general relativity do not warrant the claim that these theories describe 'object-free' structures. We conclude that category theory offers little if any comfort to ROSR.

description: The concentration of cadmium (Cd), lead (Pb), arsenic (As) and chromium (Cr) in teff straw, water and milk were studied in East and West Shoa, Ethiopia. The concentration of heavy metals in feed, water and milk were investigated using Graphite Furnace Atomic Absorption Spectrophotometer. Heavy metals in teff straw in West and East Shoa were 1543.54 Â± 318.70 Î¼g/kg and 1486.92 Â± 279.73 Î¼g/kg, respectively and were found in the order of Cr > As > Pb > Cd. The concentration of heavy metals in water in East Shoa (28.08 Â± 7.02 Î¼g/L) was significantly higher (p<0.05) than in West Shoa (1.96 Â± 0.28 Î¼g/L) and were in the order of Cr > As > Pb > Cd. Water samples obtained from Mojo Tannery had the highest level of heavy metals (86.89 Î¼g/L) followed by Mojo Lake (67.89 Î¼g/L) and a river near Mojo town (43.64 Î¼g/L). Except for pH of water from Mojo Lake (10.4) and Gelan dye factory (8.9), the rest of water samples from East Shoa were found within the recommended pH limit of 6.5-8.5 for livestock drinking. Water samples from West Shoa had an average pH of 7.0 ranging 6.4â€“7.7 and were within the permitted limit. Water from Mojo had the highest concentration of Cr and the contamination level of heavy metals in water from East Shoa was in the order Mojo > Awash River > Gelan > Akaki > Bishoftu. The concentration of heavy metals in water from East Shoa was more than ten times higher than West Shoa. The concentration of heavy metals in livestock water in the study areas did not pass the standard limit. The overall concentrations of heavy metals in milk were in the order Cr > Cd > Pb > As. Compared to WHO/JECFA 1989 standards, the concentrations of Cd and As in milk were within the permitted limits, whereas the concentrations of Cr and Pb were found beyond the standard limit. It is concluded that the level of heavy metals near industrial areas were higher than those sites in non-industrial areas. It is recommended that further study is required on heavy metals content of soils, fodder feeds and livestock products in these study areas.

Spin dynamics are successfully described by a Heisenberg localized spin model whose dominant in-plane interactions include only the nearest (J1 and J1') and next nearest neighbor (J2 and J2') exchange terms within and between the tetramer spin blocks, respectively. These experimentally determined exchange constants would crucially constrain the theoretical viewpoints on magnetism and superconductivity in the Fe-based materials.

description: The grinding process is still an important manufacturing process for the machining of automotive components. For power train components, ultra-high carbon steel (UHC-steel) is a promising new innovative alloy because of its low specific density. Results from turning of UHC-steel showed that the texture of UHC-steel significantly differs from conventional steels. Furthermore, extremely hard carbides, which are embedded into a soft ferrite matrix, result in a UHC-steel specific machining behavior and a high tool wear rate. Therefore, UHC-steel is marked as a difficult-to-cut material. So far, there are no research results available for the grinding of UHC-steel. Therefore, fundamental investigations were conducted in order to analyze the material removal and chip formation mechanisms. Scratching tests with a geometrically defined cubic boron nitride cutting edge showed ductile material removal mechanisms for a single grain chip thickness variation from hcu = 1.5 up to 14 μm. Analysis of the contact zone by means of an innovative quick stop device confirms these results. The final publication is available at Springer via http://dx.doi.org/10.1007/s00170-017-0270-9

description: The effect of jet Reynolds number, jet exit angle, the nozzle to surface distance, jet to jet spacing on the heat transfer, and pressure force performance from multiple impinging round jets on a moving curved surface have been numerically evaluated. Two correlations are developed and validated for the average Nu number and the pressure force coefficient and the agreement between the CFD and correlations was reasonable. The surface motion effect becomes more pronounced on the Nu number distribution for low jet Re number, high jet to jet spacing, large jet to surface distance, and angled jets. The pressure force coefficient is highly dependent on the jet to surface distance and jet angle but relatively insensitive to jet Re number and jet to jet spacing. © 2022, International Scientific Information, Inc..

description: A fault gouge forms at the core of the fault as the result of a slip in the upper brittle crust. Therefore, the deformation mechanisms and conditions under which the fault gouge was formed can document the stages of fault movement in the crust. We carried out a microstructural analysis on a fault gouge from a hanging-wall branch fault of the Simplon Fault Zone, a major low-angle normal fault in the Alps. We use thin-section analysis, together with backscattered electron imaging and X-ray diffractometry (XRD), to show that a multistage history from ductile to brittle deformation, together with a continuous exhumation history from high to low temperature, took place within the fault gouge. Because of the predominance of pressure solution and veining, we associated a large part of the deformation in the fault gouge with viscous-frictional behaviour that occurred at the brittle-ductile transition. Phyllosilicates and graphite likely caused fault lubrication that we suggested played a role in the formation of this major low-angle normal fault. © 2022 by the authors.

description: The effect of surface curvature, number of jets, number of jet rows, jet arrangement, crossflow, and surface motion on the heat transfer and pressure force performance from multiple impinging round jets on the moving flat and curved surface have been numerically evaluated. The more number of jets (more than three jets) has no significant effect on the average heat transfer rate. The more number of jet rows increases the strength of wall jets interference and crossflow effects and degrade the average heat transfer rates. There is a minor difference between inline and staggered arrangements on both moving flat and curved surfaces. The surface motion has a stronger effect on the impinging jets in the intermediate crossflow scheme than in the minimum crossflow scheme. The total average Nu on both moving flat and curved surfaces reduces with an increase in the velocity ratio and surface curvature. The pressure force is relatively insensitive to the surface motion on both moving flat and curved surfaces. © 2022, International Scientific Information, Inc.. All rights reserved.

description: We report the results of a multimessenger search for coincident signals from the LIGO and Virgo gravitational-wave observatories and the partially completed IceCube high-energy neutrino detector, including periods of joint operation between 2007–2010. These include parts of the 2005–2007 run and the 2009–2010 run for LIGO-Virgo, and IceCube’s observation periods with 22, 59 and 79 strings. We find no significant coincident events, and use the search results to derive upper limits on the rate of joint sources for a range of source emission parameters. For the optimistic assumption of gravitational-wave emission energy of 10−2 M⊙c2 at ∼150 Hz with ∼60 ms duration, and high-energy neutrino emission of 1051 erg comparable to the isotropic gamma-ray energy of gamma-ray bursts, we limit the source rate below 1.6×10−2 Mpc−3 yr−1. We also examine how combining information from gravitational waves and neutrinos will aid discovery in the advanced gravitational-wave detector era. © 2014 The American Physical Society

description: The frustrated triangular Ising magnet Ca$_3$Co$_2$O$_6$ has long been known for an intriguing combination of extremely slow spin dynamics and peculiar magnetic orders, such as the evenly-spaced non-equilibrium metamagnetic magnetization steps and the long-wavelength spin density wave (SDW) order, the latter of which is essentially an emergent crystal of solitons. Recently, an elaborate field-cooling protocol to bypass the low-field SDW phase was proposed to overcome the extraordinarily long timescale of spin relaxation that impeded previous experimental studies in equilibrium, which may point to a deep connection between the low-temperature slow relaxation and the cooling process passing through the low-field SDW phase. As the first step to elucidate the conjectured connection, we investigate the magnetic field-induced deformation of the SDW state and incommensurate-commensurate transitions, thereby mapping out the equilibrium in-field phase diagram for a realistic three-dimensional lattice spin model by using Monte Carlo simulations. We also discuss Ginzburg-Landau theory that includes several Umklapp terms as well as an effective sine-Gordon model, which can qualitatively explain the observed magnetic field-induced deformation of the SDW microphases.

description: A potential thermoelectric material CuAlO$_2$ is theoretically studied. We first construct a model Hamiltonian of CuAlO$_2$ based on the first principles band calculation, and calculate the Seebeck coefficient. Then, we compare the model with that of a well-known thermoelectric material Na$_x$CoO$_2$, and discuss the similarities and the differences. It is found that the two materials are similar from an electronic structure viewpoint in that they have a peculiar pudding-mold type band shape, which is advantageous as thermoelectric materials. There are however some differences, and we analyze the origin of the difference from a microscopic viewpoint. The band shape of CuAlO$_2$ is found to be even more ideal than that of Na$_x$CoO$_2$, and we predict that once a significant amount of holes is doped in CuAlO$_2$, thermoelectric properties (especially the power factor) even better than that of Na$_x$CoO$_2$ can be expected.

description: The gravitational-wave signal GW150914 was first identified on September 14, 2015, by searches for short-duration gravitational-wave transients. These searches identify time-correlated transients in multiple detectors with minimal assumptions about the signal morphology, allowing them to be sensitive to gravitational waves emitted by a wide range of sources including binary black hole mergers. Over the observational period from September 12 to October 20, 2015, these transient searches were sensitive to binary black hole mergers similar to GW150914 to an average distance of ∼600 Mpc. In this paper, we describe the analyses that first detected GW150914 as well as the parameter estimation and waveform reconstruction techniques that initially identified GW150914 as the merger of two black holes. We find that the reconstructed waveform is consistent with the signal from a binary black hole merger with a chirp mass of ∼30 M⊙ and a total mass before merger of ∼70 M⊙ in the detector frame. © 2016 The American Physical Society

description: We present the first results of an all-sky search for continuous gravitational waves from unknown spinning neutron stars in binary systems using LIGO and Virgo data. Using a specially developed analysis program, the TwoSpect algorithm, the search was carried out on data from the sixth LIGO science run and the second and third Virgo science runs. The search covers a range of frequencies from 20 Hz to 520 Hz, a range of orbital periods from 2 to ∼2,254 h and a frequency- and period-dependent range of frequency modulation depths from 0.277 to 100 mHz. This corresponds to a range of projected semimajor axes of the orbit from ∼0.6×10−3 ls to ∼6,500 ls assuming the orbit of the binary is circular. While no plausible candidate gravitational wave events survive the pipeline, upper limits are set on the analyzed data. The most sensitive 95% confidence upper limit obtained on gravitational wave strain is 2.3×10−24 at 217 Hz, assuming the source waves are circularly polarized. Although this search has been optimized for circular binary orbits, the upper limits obtained remain valid for orbital eccentricities as large as 0.9. In addition, upper limits are placed on continuous gravitational wave emission from the low-mass x-ray binary Scorpius X-1 between 20 Hz and 57.25 Hz. © 2014 The American Physical Society

description: A study was conducted to evaluate the efficacy of neem and bitter leaf extracts in drinking water as a natural feed additive for broiler chicken on feed intake, body weight gain, feed conversion ratio (FCR) and carcass cut parameters. Unsexed one hundred ninety-two days-old Cobb 500 broiler chicks with an initial weight of 42.16±0.65 gm (mean± SD) were randomly distributed to the four treatments each with three replications in a Completely Randomized Design (CRD). The treatments were inclusion of neem and bitter (powder a mixture of 1:1 ratio) extracts at 0 ml, 2 ml, 4ml and 6 ml per litter of water for T1, T2, T3 and T4, respectively. Commercial broilers diet that contained 22 and 18% CP and 3050 and 3250 kcal/kg ME for starter and finisher phases. Feed and water were offered ad libitum throughout the experimental period. Feed offered and refused were recorded every day and feed intake (FI) was calculated as the difference between the two. At the end of the trial, four broiler chickens were randomly picked up (2 male and 2 female) from each replication and slaughtered for carcass evaluation. Average daily feed intake during the entire period was 104.49, 116.07, 118.65 and 122.32 g/bird (SEM=2.03) for T1, T2, T3 and T4, respectively, and it was significantly higher (P<0.05) for T4 compared to other treatment groups. Body weight (BW) gain during the entire experimental period was 45.95, 56.72, 57.92 and 61.95 g/bird/day (SEM = 1.88) for T1, T2, T3 and T4, respectively and significantly higher for birds that treat under T4. Feed conversion ratio (FCR) during the entire period was 2.28, 2.04, 2.04 and 1.97 (SEM = 0.04) for T1, T2, T3 and T4, respectively and also best for T4. Dressed weight was 1663.84, 1983.60, 2092.90 and 2267.60 g (SEM = 65.58) for T1, T2, T3 and T4, respectively, and it was higher in T4 than other treatments. Giblets (heart, liver, and gizzard) and crop were significantly higher (P˂0.05) for T4. It was concluded that inclusion of neem and bitter leaf extracts in 6 ml/1 L of drinking water has a good natural feed additive for broiler production.

description: Gravitational waves from a variety of sources are predicted to superpose to create a stochastic background. This background is expected to contain unique information from throughout the history of the Universe that is unavailable through standard electromagnetic observations, making its study of fundamental importance to understanding the evolution of the Universe. We carry out a search for the stochastic background with the latest data from the LIGO and Virgo detectors. Consistent with predictions from most stochastic gravitational-wave background models, the data display no evidence of a stochastic gravitational-wave signal. Assuming a gravitational-wave spectrum of ΩGW(f)=Ωα(f/fref)α, we place 95% confidence level upper limits on the energy density of the background in each of four frequency bands spanning 41.5–1726 Hz. In the frequency band of 41.5–169.25 Hz for a spectral index of α=0, we constrain the energy density of the stochastic background to be ΩGW(f)<5.6×10−6. For the 600–1000 Hz band, ΩGW(f)<0.14(f/900 Hz)3, a factor of 2.5 lower than the best previously reported upper limits. We find ΩGW(f)<1.8×10−4 using a spectral index of zero for 170–600 Hz and ΩGW(f)<1.0(f/1300 Hz)3 for 1000–1726 Hz, bands in which no previous direct limits have been placed. The limits in these four bands are the lowest direct measurements to date on the stochastic background. We discuss the implications of these results in light of the recent claim by the BICEP2 experiment of the possible evidence for inflationary gravitational waves. © 2014 The American Physical Society

description: Due to the broadcast nature of wireless medium, wireless communication is extremely vulnerable to eavesdropping attack. Physical-layer security is emerging as a new paradigm to prevent the eavesdropper from interception by exploiting the physical characteristics of wireless channels, which has recently attracted a lot of research attentions. In this paper, we consider the physical-layer security in cooperative wireless networks with multiple decode-and-forward (DF) relays and investigate the best relay selection in the presence of eavesdropping attack. For the comparison purpose, we also examine the conventional direct transmission without relay and traditional max-min relay selection. We derive closed-form intercept probability expressions of the direct transmission, traditional max-min relay selection, and proposed best relay selection schemes in Rayleigh fading channels. Numerical results show that the proposed best relay selection scheme strictly outperforms the traditional direct transmission and max-min relay selection schemes in terms of intercept probability. In addition, as the number of relays increases, the intercept probabilities of both traditional max-min relay selection and proposed best relay selection schemes decrease significantly, showing the advantage of exploiting multiple relays against eavesdropping attack.
