description: While most solids expand when heated, some materials show the opposite behavior: negative thermal expansion (NTE). In polymers and biomolecules, NTE originates from the entropic elasticity of an ideal, freely-jointed chain. The origin of NTE in solids has been widely believed to be different. Our neutron scattering study of a simple cubic NTE material, ScF3, overturns this consensus. We observe that the correlation in the positions of the neighboring fluorine atoms rapidly fades on warming, indicating an uncorrelated thermal motion constrained by the rigid Sc-F bonds. This leads us to a quantitative theory of NTE in terms of entropic elasticity of a floppy network crystal, which is in remarkable agreement with experimental results. We thus reveal the formidable universality of the NTE phenomenon in soft and hard matter.

description: Using a unique panel of rice-producing Chinese households, this paper tests off-farm employment’s effects on agricultural production. We find the sizable rural out-migration in the past two decades has had negligible effects on China’s rice production. This cannot be explained by farm labor market perfection or any technological improvements financed by off-farm income; rather, evidence points to the persistence of disguised unemployment in 21st century China.
Order Parameter to Characterize Valence-Bond-Solid States in Quantum Spin Chains

description: We propose an order parameter to characterize valence-bond-solid (VBS) states in quantum spin chains, given by the ground-state expectation value of a unitary operator appearing in the Lieb-Schultz-Mattis argument. We show that the order parameter changes the sign according to the number of valence bonds (broken valence bonds) at the boundary for periodic (open) systems. This allows us to determine the phase transition point in between different VBS states. We demonstrate this theory in the successive dimerization transitions of the bond-alternating Heisenberg chains, using the quantum Monte Carlo method.

description: This study aims to evaluate the characteristics of novel organic D-π-A-π-D class small-molecules by using carefully the density functional theory, and time-dependent density functional theory calculations. Thedesigned sequence of (D-A) BHJ-1a to BHJ-4a in organic Bulk Heterojunction (BHJ) solar cells has been comprehensively analysed. Thiéno[2,3-b]indole (TI) has been used as donor, and Diketopyrrolopyrrole (DPP) as acceptor for all compounds. In order to improve the electronic, photovoltaic, and opticalproperties, we have substituted thiophene unit with furan, thieno[2,3-b]thiophene, thiazole and thiazolothiazole as π-bridge moieties. Thus, the result shows that the wise choice of the π-bridge units plays a significant role in improving Egap, producing a high bathochromic shift, and increasing VOC as well as a theoretical power conversion efficiency (PCE) over 7%. Interestingly, BHJ-4a with suitable π-bridge presents the optimal electronic properties with low band gap (1.870 eV) and high VOC (1.534 eV). Furthermore, we have modelled a Bulk heterojunction organic photovoltaic cells based on donor-PCBM complex in order to achieve the optimum Egap and VOC. Consequently, the obtained results provide a new way to design BHJ small molecule donors with higher power conversion efficiency.
The Dynamics of Test Particles and Pointlike Gyroscopes in the Brane World and Other 5D Models

description: We study the dynamics of test particles and pointlike gyroscopes in 5D manifolds like those used in the Randall-Sundrum brane world and non-compact Kaluza-Klein models. Our analysis is based on a covariant foliation of the manifold using 3+1 dimensional spacetime slices orthogonal to the extra dimension, and is hence similar to the ADM 3+1 split in ordinary general relativity. We derive gauge invariant equations of motion for freely-falling test particles in the 5D and 4D affine parameterizations and contrast these results with previous work concerning the so-called ``fifth force''. Motivated by the conjectured localization of matter fields on a 3-brane, we derive the form of the classical non-gravitational force required to confine particles to a 4D hypersurface and show that the resulting trajectories are geometrically identical to the spacetime geodesics of Einstein's theory. We then discuss the issue of determining the 5D dynamics of a torque-free spinning body in the point-dipole approximation, and then perform a covariant (3+1)+1 decomposition of the relevant formulae (i.e. the 5D Fermi-Walker transport equation) for the cases of freely-falling and hypersurface-confined point gyroscopes. In both cases, the 4D spin tensor is seen to be subject to an anomalous torque. We solve the spin equations for a gyroscope confined to a single spacetime section in a simple 5D cosmological model and observe a cosmological variation of the magnitude and orientation of the 4D spin.

description: According to the present understanding, the observed diversity of the strong interaction phenomena is described by Quantum Chromodynamics, a gauge field theory with only very few parameters. One of the fundamental questions in this context is how precisely the world of mesons and nucleons is related to the properties of the theory at high energies, where quarks and gluons are the important degrees of freedom. The lattice formulation of QCD combined with numerical simulations and standard perturbation theory are the tools that allow one to address this issue at a quantitative level.

description: We derive a geometrical version of the Regge-Wheeler and Zerilli equations, which allows us to study gravitational perturbations on an arbitrary spherically symmetric slicing of a Schwarzschild black hole. We explain how to obtain the gauge-invariant part of the metric perturbations from the amplitudes obeying our generalized Regge-Wheeler and Zerilli equations and vice-versa. We also give a general expression for the radiated energy at infinity, and establish the relation between our geometrical equations and the Teukolsky formalism. The results presented in this paper are expected to be useful for the close-limit approximation to black hole collisions, for the Cauchy perturbative matching problem, and for the study of isolated horizons.

description: Signaling proteins are an important topic in drug development due to the increased importance of finding fast, accurate and cheap methods to evaluate new molecular targets involved in specific diseases. The complexity of the protein structure hinders the direct association of the signaling activity with the molecular structure. Therefore, the proposed solution involves the use of protein star graphs for the peptide sequence information encoding into specific topological indices calculated with S2SNet tool. The Quantitative Structure-Activity Relationship classification model obtained with Machine Learning techniques is able to predict new signaling peptides. The best classification model is the first signaling prediction model, which is based on eleven descriptors and it was obtained using the Support Vector Machines - Recursive Feature Elimination (SVM-RFE) technique with the Laplacian kernel (RFE-LAP) and an AUROC of 0.961. Testing a set of 3114 proteins of unknown function from the PDB database assessed the prediction performance of the model. Important signaling pathways are presented for three UniprotIDs (34 PDBs) with a signaling prediction greater than 98.0%.

description: Einstein's general relativity predicts that orbital motion of accreted gas approaching a neutron star (NS) in a NS low-mass X-ray binary (LMXB) system occurs on a time scale proportional to the NS mass. Radiation of the gas accounts for most of the observed LMXBs variability. In more than a dozen of sources twin-peak quasi-periodic oscillations (QPOs) have been observed. Inspired by the expected proportionality between periods of orbital motion and NS mass we present a straightforward comparison among these sources. We investigate relations between QPO periods and their ratios and identify characteristic time scales of QPOs associated to individual sources. These timescales are likely determined by the relative mass of each NS. We show that the characteristic time scale of the millisecond pulsar XTE J1807.4-294 is longer than for most other NS LMXBs. Consequently, models of QPOs that consider geodesic orbital frequencies imply that the X-ray pulsars' mass has to be about 50 % higher than the average mass of other sources. Consideration of other X-ray pulsars indicates that the exceptionality of XTE J1807.4-294 cannot be related to NS magnetic field in any simple manner. We suggest that QPOs observed in this source can help to discriminate between the proposed versions of the NS equation of state.

description: We investigate how braneworld gravity affects gravitational collapse and black hole formation by studying Oppenheimer-Snyder-like collapse on a Randall-Sundrum type brane. Without making any assumptions about the bulk, we prove a no-go theorem: the exterior spacetime on the brane cannot be static, which is in stark contrast with general relativity. We also consider the role of Kaluza-Klein energy density in collapse, using a toy model.

description: Recently, gross production of Medjool dates has approximately doubled in Arizona, with the growing region increasing to over 3,000 harvested acres in 2014. As the supply of Medjool dates increases, consumer demand needs to increase accordingly. This research aims to investigate consumer preferences for specialty crops such as Medjool dates. This paper analyzes the impact of Arizona Grown and California Grown labeling on consumer preferences for Medjool dates applying choice experiments. Furthermore, the influence of pesticide-free labeling and GMO-free labeling on willingness to pay is tested both individually and as interaction effect. Results show that consumers prefer dates grown in California and Arizona over dates not labeled for region of origin. Between California and Arizona, those dates originating in California are preferred. Also, pesticide free and GM-free dates are preferred with pesticide free having a larger impact on choices. Overall, results can be used by stakeholders to create target oriented marketing activities.

description: Vegetables have high farm gate values and their consumption can alleviate malnutrition. A study was conducted to analyze vegetable value chains in selected locations of Cameroon. Data were collected from key vegetable value chain actors and stakeholders using structured questionnaires customized for 162 producers, 65 traders, 12 exporters, 30 processors and 29 transporters in the humid tropics of Cameroon. The analysis included value chain mapping, detailed description and quantification of value chains, and economic evaluation of value chains. Most vegetable crop value chains are relatively simple, and involve only five main groups: producers, transporters, traders, processors and exporters (for traditional leafy vegetable value chains); input suppliers are a sixth category for standard vegetable chains. Vegetables are produced under different production systems adapted to the agroecological and climatic conditions of various regions. Most vegetable farmers generally have poor access to input and output market support services, including agricultural credit; this lowers their capacity to invest in their farms. What limited credit is available is typically obtained through the informal credit system, which tends to be more easily accessible by men than women. This may explain the fact that men who are engaged in vegetable farming earn much higher incomes than women. Our economic analysis of the value chain shows a benefit-cost ratio > 1 for vegetable production, processing and marketing. This indicates the vegetable sector is generally profitable for all actors along the chain, although there are wide disparities in earnings as different actors are subject to site-specific market conditions, constraints, and circumstances.

description: This study estimates the proportion of dry bean yield increase in South African Agricultural Research Council (ARC) released dry bean cultivars that are attributable to genetic improvements through the ARC breeding program. Using data from 32 test plots across South Africa, the study quantifies the yield and yield variance evolution attributable to the breeding program. In addition, this study calculates the economic benefits to small landholder’s attributed to the ARC dry bean breeding program. Results indicated that by releasing modern dry bean cultivars, the ARC dry bean breeding program increased average producer yield by 11.42 kg/ha annually. During the period of 1972 to 2014, the ARC Breeding Program contributed 489.36 kg/ha cumulatively (11.42*42) to dry bean yields solely from genetic improvements, which is equivalent to a 23.15% (489.36/1130.78) increase in producer yields. The benefits associated only with the genetic gains from the breeding program are estimated to be 701.4 million Rand (46.8 million USD) from 1992-2014. Using historic ARC breeding costs the benefit cost ratio was estimated to be 5.67:1. Like every other country in the world South Africa continuously has to battle for agricultural R&D funds to support programs like ARC whose role is to help small scale producers in Africa. As such, we find the annual genetic gain attributed to the ARC Breeding Program has increased, and the returns to the breeding program continue to play a large role for dry bean farmers and consumers in combating food insecurity.

description: In this paper, we present the StarNEig library for solving dense non-symmetric (generalized) eigenvalue problems. The library is built on top of the StarPU runtime system and targets both shared and distributed memory machines. Some components of the library support GPUs. The library is currently in an early beta state and only real arithmetic is supported. Support for complex data types is planned for a future release. This paper is aimed for potential users of the library. We describe the design choices and capabilities of the library, and contrast them to existing software such as ScaLAPACK. StarNEig implements a ScaLAPACK compatibility layer that should make it easy for a new user to transition to StarNEig. We demonstrate the performance of the library with a small set of computational experiments.

description: We present the first experimental determination of the time autocorrelation $C(t',t)$ of magnetization in the non-stationary regime of a spin glass. Quantitative comparison with the response, the magnetic susceptibility $χ(t',t)$, is made using a new experimental setup allowing both measurements in the same conditions. Clearly, we observe a non-linear fluctuation-dissipation relation between $C$ and $χ$, depending weakly on the waiting time $t'$. Following theoretical developments on mean-field models, and lately on short range models, it is predicted that in the limit of long times, the $χ(C)$ relationship should become independent on $t'$. A scaling procedure allows us to extrapolate to the limit of long waiting times.

description: We present new, highly accurate, measurements of the fundamental band of the roto-vibrational Raman spectrum of molecular nitrogen and oxygen. Experimentally obtained spectra were used as a basis to derive information about the anisotropy of the polarisability tensor, including its dependence on rotational state due to molecular non-rigidity. Third-order perturbative calculations were used to determine corrections to the Raman scattering cross sections as a function of the rotational quantum numbers. Our results for the ratio of polarisability anisotropy at equilibrium divided by its first derivative for nitrogen are in agreement with values reported previously and are significantly different from historical data obtained for oxygen.

Two Irregularity Measures Possessing High Discriminatory Ability

description: An $n$-vertex graph whose degree set consists of exactly $n-1$ elements is called antiregular graph. Such type of graphs are usually considered opposite to the regular graphs. An irregularity measure ($IM$) of a connected graph $G$ is a non-negative graph invariant satisfying the property: $IM(G) = 0$ if and only if $G$ is regular. The total irregularity of a graph $G$, denoted by $irr_t(G)$, is defined as $irr_t(G)= \sum_{\{u,v\} \subseteq V(G)} |d_u - d_v|$ where $V(G)$ is the vertex set of $G$ and $d_u$, $d_v$ denote the degrees of the vertices $u$, $v$, respectively. Antiregular graphs are the most nonregular graphs according to the irregularity measure $irr_t$; however, various non-antiregular graphs are also the most nonregular graphs with respect to this irregularity measure. In this note, two new irregularity measures having high discriminatory ability are devised. Only antiregular graphs are the most nonregular graphs according to the proposed measures.

description: Climate change and variability and soil fertility depletion are among the main biophysical limiting factors for increasing per capita food production for smallholder farmers in developing countries. To tackle these challenges, the adoption of sustainable agricultural practices (SAPs), has become an important policy topic among donors and development agencies in developing countries. This paper examines the adoption decisions for SAPs, using recent primary data collected in 51 villages in 3 districts of Zimbabwe. The article employs a multivariate probit regression to model simultaneous interdependent adoption decisions by farm households. The analysis reveals that education, farm experience, farm size, income, access to information and agroecology influence the adoption of SAPs. Policies that are aimed at improving household income and enhancing access to information can increase the uptake of SAPs by smallholder farmers. Extension messages should aim to emphasize the complementarities between different SAPs. This information could help policy makers and extension agents to formulate and promote a package of SAPs.

description: This paper clarifies the path that Rwanda took in the quest for a modern, intensive, productive and market-oriented agriculture. The facts presented here have been collected by means of documentation that led to the review of different publications including published papers and government and development partners’ reports. The paper shows that an adequate policy and institutional environment has been created by various socio-economic, institutional and agriculture-led reforms launched since the early 2000s. The literature review reveals that impressive results have been recorded in regard to smallholder agriculture intensification. In addition, the theoretical model for progressive smallholder agriculture transformation helped to show that most of the smallholders grouped in cooperatives are at the 'semi-commercial smallholders' stage while only a few are at the 'commercial smallholders' and 'advanced farmers' stages. This study also examines various challenges that hamper the sustainable intensification of smallholder agriculture at both institutional, community and smallholder level. It suggests some policy actions to be put forward by the government and other agriculture sector development partners to address those challenges.
Spectrum of the fully-heavy tetraquark state $QQ\bar Q' \bar Q'$

description: In this work, we systematically calculate the mass spectra of the $S$-wave fully heavy tetraquark states $bb\bar b\bar b$, $cc\bar c\bar c$, and $bb\bar c\bar c$ in two nonrelativistic quark models. A tetraquark state may be an admixture of a $6_c-\bar 6_c$ state and a $\bar 3_c-3_c$ one, where $6_c-\bar 6_c$($\bar 3_c-3_c$) denotes the color configuration with a $6_c$ ($\bar 3_c$) diquark and a $\bar 6_c$ ($3_c$) antidiquark. For the tetraquark states $bb\bar b\bar b$ and $cc\bar c\bar c$ with $J^{PC}={0^{++}}$, the $6_c-\bar 6_c$ state is lower than the $\bar 3_c-3_c$ one in both the two quark models, while the order of the $bb\bar c\bar c$ states depend on models. The $6_c-\bar 6_c$ and $\bar 3_c-3_c$ mixing effects are induced by the hyperfine interactions between the diquark and antidiquark, while the contributions from the one-gluon-exchange (OGE) Coulomb or the linear confinement potentials vanish for the $QQ\bar Q'\bar Q'$ system. With the couple-channel effects, we obtain the similar mass spectra. The numerical results show that the ground $QQ\bar Q'\bar Q'$ ($Q=b,c$ and $Q'=b,c$) tetraquark states are located above the corresponding scattering states, which indicates that there may not exist a bound state in the scheme of the two quark models.

Strangelets as Cosmic Rays beyond the Greisen-Zatsepin-Kuzmin Cutoff

description: Strangelets (stable lumps of quark matter) can have masses and charges much higher than those of nuclei, but have very low charge-to-mass ratios. This is confirmed in a relativistic Thomas-Fermi model. The high charge allows astrophysical strangelet acceleration to energies orders of magnitude higher than for protons. In addition, strangelets are much less susceptible to the interactions with the cosmic microwave background that suppress the flux of cosmic ray protons and nuclei above energies of $10^{19}$--$10^{20}$ eV (the GZK-cutoff). This makes strangelets an interesting possibility for explaining ultra-high energy cosmic rays.

description: We analyze how the nutrition transition, which involves a westernization of diets and increased consumption of calorie-dense, processed foods, affects child malnutrition in developing countries. It is often assumed that the nutrition transition affects child weight but not child growth, which could be one reason why child underweight decreases faster than child stunting. But these effects have hardly been analyzed empirically. Our cross-country panel regressions show that the nutrition transition reduces child underweight, while no consistent effect on child overweight is found. Against common views, our results also suggest that the nutrition transition reduces child stunting. Further research is required to confirm these findings.

description: We demonstrate and characterize first superconducting nanowire single-photon detectors (SNSPDs) made from atomic layer-deposited (ALD) NbN layers. To assess the suitability of these films as a detector material, transport properties of bare films and bridges of different dimensions and thicknesses are investigated. Similar ratios of the measured critical current to the depairing current are obtained for micro-bridges made from ALD and sputtered NbN films. Furthermore, we characterized the single-photon response for 5 and 10 nm-thick nanowire detectors. A 100 nm-wide straight nanowire with a length of 5 $μ$m exhibits saturated count-rate dependencies on bias current and a cut-off wavelength in the near-infrared range. The ALD technique could open up the possibility to fabricate NbN-based detectors on the wafer scale and to conformally cover also non-planar surfaces for novel device concepts.
