description: Indole-3-acetic acid (IAA) is a natural plant hormone which can also be used as a plant growth regulator. However, its usage on crops is not permitted in the EU, with a maximum residue limit (MRL) currently set at 0.1 mg kg−1 for all food commodities. As available data on the occurrence of IAA in food commodities are limited, this work aims at evaluating the amount of IAA in important food commodities such as coffee and cereals, but also selected processed ingredients such as cocoa and malt. In total, 133 samples representing 18 different food commodities were analysed for the occurrence of free IAA using a liquid chromatography high resolution mass spectrometry method. IAA was detected in all samples except malt powders and tomatoes. The analysed crops were either grown under conventional, organic, or strictly controlled (i.e. excluding the use of IAA as pesticide/plant growth regulator) farming conditions. No significant differences in the amounts of IAA were found in crops grown under the three different farming conditions. A high percentage of the samples (63%) showed levels of free IAA above the EU MRL. We therefore conclude that the natural abundance of IAA was not properly assessed prior to the establishment of some current EU MRLs. Based on the natural occurrence of IAA in a wide range of foods; we question the need for an MRL for IAA in plant-based foods.

Social Media and New Politics in the Middle East

description: Social media determined dramatic changes in the balance of political power in the Arab world and in Israel. In the new politics of the Middle East the political environment and the communications between people are different then what used to be before 2011. Two major civil demonstrations – the Arab Spring and the Israeli Social Justice movement - were motivated by the masses through social media and received tremendous media coverage. The revolutions proved that the internet is truly a powerful tool that changed the world in ways that no government can stop social movements. The research finds similarities between the uprisings in the Arab world and in Israel, which created a new environment of "new politics." The uprisings that began on Facebook, and Twitter changed the way societies function and caused governments to change old policies. Despite the long-lasting conflict in the Middle East, involving the Palestinian issue, which traditionally occupied governments and public agenda, the uprisings raised social and economic issues. The events started with isolated acts of young people through social media and brought together people from all walks of life and across all political spectrums. The legitimacy of the protest to be considered as social revolution came only after the media started live transmissions – global media of the Arab Spring and Israel's national media services of the Social Justice movement. This proves the crucial role of traditional media, since only after the social media revolution was accepted by the media, a new reality could be created, in which the public rather than governments and social media and not the traditional media are dictating public agenda and enforcing political changes.

description: Tropospheric ozone is an important ambient atmospheric pollutant component in urban areas. Determining plant reactions to ozone in plant growth and biochemical quality contents plays an important role in understanding plant metabolism. This study aimed to provide an understanding of the effect of ozone on early vegetative growth stage Pak-Choi (Brassica campestris L. ssp. chinensis). An experiment was conducted within an airtight bio-chamber for six consecutive days under 60 ppb ozone concentration. Different exposure duration conditions were 0 h/day, 1 h/day, and 4 h/day. The results showed no reaction of plant growth, but ozone exposure led to significant impacts in biochemical quality. The content of photopigments was not significantly impacted at 1 h/day, but significantly increased at the 4 h/day exposure condition. There was a significant decrease in the total glucosinolate (GLS) and total aliphatic GLS after the 4 h/day exposure condition; however, 4-

description: The kagome lattice based on 3d transition metals is a versatile platform for novel topological phases hosting symmetry-protected electronic excitations and exotic magnetic ground states. However, the paradigmatic states of the idealized two-dimensional (2D) kagome lattice - Dirac fermions and topological flat bands - have not been simultaneously observed, partly owing to the complex stacking structure of the kagome compounds studied to date. Here, we take the approach of examining FeSn, an antiferromagnetic single-layer kagome metal with spatially-decoupled kagome planes. Using polarization- and termination-dependent angle-resolved photoemission spectroscopy (ARPES), we detect the momentum-space signatures of coexisting flat bands and Dirac fermions in the vicinity of the Fermi energy. Intriguingly, when complemented with bulk-sensitive de Haas-van Alphen (dHvA) measurements, our data reveal an even richer electronic structure that exhibits robust surface Dirac fermions on specific crystalline terminations. Through band structure calculations and matrix element simulations, we demonstrate that the bulk Dirac bands arise from in-plane localized Fe-3d orbitals under kagome symmetry, while the surface state realizes a rare example of fully spin-polarized 2D Dirac fermions when combined with spin-layer locking in FeSn. These results highlight FeSn as a prototypical host for the emergent excitations of the kagome lattice. The prospect to harness these excitations for novel topological phases and spintronic devices is a frontier of great promise at the confluence of topology, magnetism, and strongly-correlated electron physics.

description: The Schroedinger operator with point interaction in one dimension has a U(2) family of self-adjoint extensions. We study the spectrum of the operator and show that (i) the spectrum is uniquely determined by the eigenvalues of the matrix U belonging to U(2) that characterizes the extension, and that (ii) the space of distinct spectra is given by the orbifold T^2/Z_2 which is a Moebius strip with boundary. We employ a parametrization of U(2) that admits a direct physical interpretation and furnishes a coherent framework to realize the spectral duality and anholonomy recently found. This allows us to find that (iii) physically distinct point interactions form a three-parameter quotient space of the U(2) family.

description: Renewable energy sources and green-technologies are required to mitigate carbon-based fuel consumption, but they require increasing amounts of raw materials. Critical metals are abundant in ocean-floor iron-manganese deposits. However, the nature of their association with iron and manganese oxide minerals and exchangeability with water remain poorly understood. Advancing our knowledge in this field is important in order to understand biogeochemical metal cycling in marine environments and to develop tailored metal processing techniques. These will aid in unlocking metals through zero-waste approaches which help reduce environmental impacts of mining.

description: This paper addresses the balance between different crops and its determination by research investment. This balance results from the cropping-plan decision of the farmers. This decision depends on various factors such as the seed performance, the pest problems, the output prices, etc. We show how the introduction of a productivity decrease due to the market size of each crop is likely to set out a more equilibriated market. Further, our model analysis the main determinants of research investment by a monopoly, and shows that this investment tends to equilibrate the market.

description: Elementary excitations in condensed matter capture the complex many-body dynamics of interacting basic entities in a simple quasiparticle picture. In magnetic systems the most established quasiparticles are magnons, collective excitations that reside in ordered spin structures, and spinons, their fractional counterparts that emerge in disordered, yet correlated spin states. Here we report on the discovery of elementary excitation inherent to spin-stripe order that represents a bound state of two phason quasiparticles, resulting in a wiggling-like motion of the magnetic moments. We observe these excitations, which we dub "wigglons", in the frustrated zigzag spin-1/2 chain compound $β$-TeVO$_4$, where they give rise to unusual low-frequency spin dynamics in the spin-stripe phase. This result provides insights into the stripe physics of strongly-correlated electron systems.

description: When manufacturing oral premixes, cross-contamination may occur between medicated and non-medicated feed leading to the exposure of food-producing animals to low concentrations that may result in antimicrobial residues in edible products. This project was designed to assess the level of antibiotic residues in edible pig tissues, faeces and plasma after exposure for 12 days to feed contaminated with sulphadimethoxine/trimethoprim (2% of the therapeutic dosage). Our results show that sulphadimethoxine concentrations can significantly exceed the maximum residue limits (MRL) in liver (618 ± 96 µg/kg) and kidneys (510 ± 73 µg/kg), and that putative metabolites can also be detected in the liver. Based on tissue and plasma data, a pharmacokinetic model was developed to assess which contamination rates would not result in residue concentrations above the MRL. Our simulations show that the contamination rate should remain below 0.2% of the therapeutic dose, i.e. far lower of the tolerated contamination rate.

description: This paper presents ASCA/SIS and ROSAT/HRI results of three supernova remnants (SNRs) in the Small Magellanic Cloud: 0103-726, 0045-734, and 0057-7226. The ROSAT/HRI images of these SNRs indicate that the most of the X-ray emissions are concentrated in the center region. Only from 0103-726 are faint X-rays along the radio shell also detected. The ASCA/SIS spectra of 0103-726 and 0045-734 exhibit strong emission lines from highly ionized metals. The spectra were well-fitted with non-equilibrium ionization (NEI) plasma models. The metal abundances are found to be larger than the mean chemical compositions in the interstellar medium (ISM) of the SMC. Thus, X-rays from these two SNRs are attributable to the ejecta gas, although the ages estimated from the ionization timescale are significantly large, ~> 10^4 yr. The chemical compositions are roughly consistent with the type-II supernova origin of a progenitor mass ~< 20 M_solar. The SIS spectrum of 0057-7226 was also fitted with an NEI model of an estimated age ~> 6 x 10^3 yr. Although no constraint on the metal abundances was obtained, the rather weak emission lines are consistent with the low metal abundances in the ISM of the SMC. A possible scenario for the evolution of the morphologies and spectra of SNRs is proposed.

description: Productivity in strawberry (Fragaria × ananassa) can be recorded by measuring marketable or total yield. The first objective of this review was to determine if marketable yield can be predicted from total yield. The second objective of this review was to develop protocols to accurately determine the productivity of strawberry cultivars. Previous research has not examined the relationship between the two measures of productivity and how to best measure the yield of strawberry cultivars. The relationship between marketable and total yield was assessed by examining the performance of strawberry cultivars across 68 studies. Marketable yield had a linear, but inconsistent relationship with total yield across different cultivars, sites and years. The slope from the regression between marketable and total yield ranged from 0.25 to 0.99, with a median of 0.80, and a mean (and SE) of 0.78 ± 0.01. Marketable yield cannot be predicted from total yield. The results of this review demonstrate that marketable yield is a better indicator of productivity than total yield. Both measures of productivity should be used in future cultivar studies. The results also demonstrate that cultivar experiments that include information on the incidence of fruit defects are better than ones that do not.

description: Nearby merging pairs are unique laboratories in which one can study the gravitational effects on the individual interacting components. In this manuscript, we report the characterization of selected HII regions along the peculiar galaxy NGC 2936, member of the galaxy pair Arp 142, an E+S interaction, known as "The Penguin". Using Gemini South spectroscopy we have derived a high enhancement of the global star formation rate SFR=35.9 Msun/yr probably stimulated by the interaction. Star-forming regions on this galaxy display oxygen abundances that are consistent with solar metallicities. The current data set does not allow us to conclude any clear scenario for NGC 2936. Diagnostic diagrams suggest that the central region of NGC 2936 is ionized by AGN activity and the eastern tidal plume in NGC 2936 is experiencing a burst of star formation, which may be triggered by the gas compression due to the interaction event with its elliptical companion galaxy: NGC 2937. The ionization mechanism of these sources is consistent with shock models of low-velocities of 200-300 km/s The isophotal analysis shows tidal features on NGC 2937: at inner radii non-concentric (or off-centering) isophotes, and at large radii, a faint excess of the surface brightness profile with respect to de Vaucouleurs law. By comparing the radial velocity profiles and morphological characteristics of Arp 142 with a library of numerical simulations, we conclude that the current stage of the system would be about 50 +-25 Myr after the first pericenter passage.

 Remarks. In the original description by Walter (1922), the tube-like petiole has an upper margin with a pointed extension. Halbert (1906) reported the species from Lake Nyasa, Tanzania (as A. plenipalpis Koenike, 1893, later assigned to A. forcipetiolatus by K. Viets 1942 - but assignment questioned by K.O. Viets 1972). Halbert illustrated the tube-like petiole with a rounded extension, like the species from this study. Lundblad (1942), too, illustrated the upper margin of the petiole with a (very) short, rounded extension. The male from this study is 1013 long and 753 wide, the dorsal shield is 458 long and 498 wide. Near the posterior end of the cleft there is a hyaline extension, of which the shape cannot be determined exactly (although Lundblad described these extensions as triangular). The females of this study are 1136–1196 long and 891–948 wide, the complete dorsal shield is 851– 855 long and 591–640 wide. It must be noted that the two females differ considerably in shape of the idiosoma, coxal plates and genital plates.
Previously, the species has been reported from Sudan (Walter 1922), Zimbabwe (Halbert 1906), Ethiopia (Lundblad 1942) and South Africa (only ♀, Bader & Jansen van Rensburg 1969).

description: This study analyzes the dynamics of direct-to-consumer marketing by U.S. farms using data from the U.S. Census of Agriculture. We analyze transition probabilities across categories of states based on the value of direct-to-consumer sales. Census-to-Census transition matrices shows high transition rates toward no direct sales amongst farmers. Our findings indicate that farmers do not necessarily have a strong commitment to direct-to-consumer marketing channels, particularly for very small farms that are also livestock farms. Probit models indicate that farmers who continue to engage in direct marketing are more likely to have a higher proportion of direct-to-consumer sales to all sales, are more likely to produce fruit or vegetablesand less likely to produce livestock in comparison to other crops, and are more likely to be larger farms. These results inform policy makers about the dynamics in direct-to-consumer marketing by U.S. farmers.

description: We discuss a formulation of harmonic superspace approach for noncommuative N=2 supersymmetric field theories paying main attention on new features arising because of noncommutativity. We begin with the known notions of the harmonic superfield models and results obtained and consider how these notions and results are modified in the noncommutative case. The actions of basic N=2 models, like hypermultiplet and N=2 vector multiplet, are given in terms of unconstrained off-shell superfields on noncommutative harmonic superspace. We calculate the low-energy contributions to the effective actions of these models. The background field method in noncommutative harmonic superspace is developed and it is applied to study the 1-loop effective action in general noncommutative N=2 model and N=4 SYM theory.

description: High temperature superconductors are strongly coupled systems which present a complicated phase diagram with many coexisting phases. This makes it difficult to understand the mechanism which generates their singular transport properties. Hydrodynamics, which mostly relies on the symmetries of the system without referring to any specific microscopic mechanism, constitutes a promising framework to analyze these materials. In this paper we show that in the strange metal phase of the cuprates, a whole set of transport coefficients are described by a universal hydrodynamic framework once one accounts for the effects of quantum critical charge density waves. We corroborate our theoretical prediction by measuring the DC transport properties of Bi-2201 close to optimal doping, proving the validity of our approach. Our argument can be used as a consistency check to understand the universality class governing the behavior of high temperature cuprate superconductors.

description: Transgenic walnuts (Juglans regia L.) were produced in the presence of the Agrobacterium strain LBA4404 and the plasmid pBI121. This plasmid contains a BADH gene driven by a CaMV 35S promoter. It further includes an NPTII gene as a selectable marker which, in turn, is driven by a NOS promoter. Somatic embryos of the walnut cultivar ‘Chandler’ were inoculated using an Agrobacterium suspension. Secondary embryos that developed on a selection medium were driven towards germination so as to develop micro-shoot cultures. The regeneration rate was 5.5%. PCRand southern blot analysis were used for confirming that the BADH transgene is successfully integrated into the plant genome. Transgenic and wild-type plants raised from somatic embryos were exposed to four osmotic stress levels (i.e. 0%, 2%, 4%, and 8% PEG) and four salinity levels (i.e. 0, 50, 100, and 200 mM NaCl). After 21 days, the transgenic plants grew almost vigorously in saline and drought-stress conditions, whereas the wild-type ones showed retarded levels of growth and did not survive after the cradle stage. These results show that the BADH gene can be expressed effectively in transgenic plantlets of walnut and can be used for breeding walnuts against drought and salinity.

description: In this paper we analyse whether the event of succession changes the performance of farms, for the case of Italian family farms during the period 2008-2014. We using data from the Italian Farm Accountancy Data Network (FADN) and several performance indicators. Analyses based on t-tests of equality of means and propensity score matching reveal that succession has a negative effect on performance indicators related to capital, revealing that the capital value has increased after succession. In addition, for farms with succession in the first years of the period considered, performance per hectare after succession is lower for those farms than for farms in which no succession occurred. But this negative effect of succession on performance per hectare is not systematically confirmed when performance is related per labour unit.

description: The taxonomic validity of the East African reed frogs Hyperolius mitchelli Loveridge, 1953 and Hyperolius rubrovermiculatus Schiøtz, 1975 has been questioned in the literature, with the latter having been recognised as a distinct lineage, but also synonymised as a colour variant of H. mitchelli. The recent description of a new closely related congener from Mozambique, Hyperolius stictus (Conradie et al., 2018), along with evidence of genetic differentiation within H. mitchelli has suggested that this widely distributed species might be a species complex. In this study, we reassess the relationships of these closely related species with new field sampling, molecular, morphological and bioacoustics analyses with the aim to assign the correct taxonomic identity to H. cf. mitchelli from northern Tanzania. Our results demonstrate that there are four distinct lineages within this group: H. stictus from Mozambique; H. rubrovermiculatus from southern Kenya; H. mitchelli sensu stricto from central and southern Tanzania and Malawi and H. cf. mitchelli from north-eastern Tanzania. Based on our combined analyses we assign H. cf. mitchelli as a new population of H. rubrovermiculatus with distinct colouration, extending the range of this species from Kenya into northern Tanzania. We also clarify the genetic, morphological and acoustic variation within and between all lineages to further knowledge of this group and provide direction for future study into this fragmented and variable lineage.

description: Recently, entanglement teleportation has been investigated in Phys. Rev. Lett. 84, 4236 (2000). In this paper we study entanglement teleportation via two separate thermally entangled states of two-qubit Heisenberg XX chain. We established the condition under which the parameters of the model have to satisfy in order to teleport entanglement. The necessary minimum amount of thermal entanglement for some fixed strength of exchange coupling is a function of the magnetic field and temperature.

description: The aim of this work was to study the effect of postharvest light treatment as a potential degreening method on ‘Okitsu’ Satsuma mandarin (Citrus reticulata Blanco). Furthermore, a possible synergistic effect of light and ethephon treatment was also evaluated. For this, mature green fruit were harvested and treated. The treatments were: 1) exposing the fruit to increasing periods of time of photosynthetically active radiation (PAR); 2) the combination of a traditional ethephon degreening method with the most effective PAR treatment. The results show that 12 h and 24 h of PAR treatments were the most favourable to obtain the better effects of degreening, not affecting the rest of quality parameters. The combination of the 24 h of PAR and ethephon treatments was not effective to degreen the fruit. The present work is the first step in the approach to the study of PAR treatment as a degreening method on citrus and, according to the results, we consider it could be a promising degreening treatment on ‘Okitsu’ mandarin.

description: In various applications, design problems involving structures and compliant mechanisms experience fluidic pressure loads. During topology optimization of such design problems, these loads adapt their direction and location with the evolution of the design, which poses various challenges. A new density-based topology optimization approach using Darcy's law in conjunction with a drainage term is presented to provide a continuous and consistent treatment of design-dependent fluidic pressure loads. The porosity of each finite element and its drainage term are related to its density variable using a Heaviside function, yielding a smooth transition between the solid and void phases. A design-dependent pressure field is established using Darcy's law and the associated PDE is solved using the finite element method. Further, the obtained pressure field is used to determine the consistent nodal loads. The approach provides a computationally inexpensive evaluation of load sensitivities using the adjoint-variable method. To show the efficacy and robustness of the proposed method, numerical examples related to fluidic pressure loaded stiff structures and small-deformation compliant mechanisms are solved. For the structures, compliance is minimized, whereas for the mechanisms a multi-criteria objective is minimized with given resource constraints.

description: Organophosphate esters (OPEs) have raised great concerns in recent years. However, information regarding their occurrence in infant formula remains limited. Thus, thirty-two OPEs were measured in infant formula sold in Shanghai, China in 2023. The results showed that OPE occurrence in infant formula was widespread. The median concentrations of organophosphate diesters, organophosphate triesters, and total OPEs were 2.28, 5.20, and 8.63 ng/g, respectively. Tris(2-chloroisopropyl) phosphate (TCPP) showed the highest median concentration (1.95 ng/g), followed by triethyl phosphate, bis(1-chloro-2-propyl) phosphate (BCPP), tri-isobutyl phosphate, and triphenyl phosphate (0.532–0.581 ng/g). The dominant chloro-OPEs (TCPP and BCPP) were regional-specific. Compared to corresponding triesters, the diester concentrations were often lower, except for bis(2-butoxyethyl) phosphate and tributoxyethyl phosphate. Additionally, five novel OPEs with phenyl groups were identified, showing high detection frequencies and comparable concentrations to TCPP. Raw materials and food processing methods might affect individual OPEs. The estimated daily intakes (EDIs) ranged from 62.3 to 355 ng/kg bw/day. The highest EDI occurred in infants of 0–6 months of age but posed no obvious health risk for infants and toddlers. Further studies are still needed to evaluate the possible health implications arising from the novel OPEs and their metabolites, as well as the potentially synergistic effects.

description: During the past decade the U.S. dairy market has been subject to periodic swings in dairy commodity and milk prices. The U.S. All Milk price reached an historic high of $21.90 (nominal dollars) per hundredweight in November, 2007 before retreating to a low of $11.30 recorded in June of 2009. This rapid decline in milk price has become the focal point for the claim of ‘excess volatility’ in milk prices and a call for the introduction of a federal government mandated supply management program for U.S. dairy production sector. This program, if adopted, would be included in the next dairy title of the 2012 agricultural farm legislation, and is outlined in two bills, the Costa bill HR5288 and the Sanders bill S-82010. The intent of these proposed programs would be to greatly diminish this perceived ‘volatility’ in milk price. The research approach will be to use modern time-series modeling techniques to determine the nature of the ‘volatility’ versus ‘variability’ in milk and dairy product prices over the past ten years. The empirical analysis will assess the variability for both dairy commodity prices (butter, cheese, nonfat dry milk, and whey), and a proxy for the Federal Order 33 Blend Price. The results of this empirical investigation reveal that while dairy commodity prices exhibit significant periods of volatility and volatility spikes, there is no evidence that this volatility is growing over time. Following upward swings in volatility dairy prices and the farm milk price return to lower levels represented by the long run variance for each price series.

description: The U.S. avocado industry has evolved from an emphasis on seasonal domestic production of a mix of avocado varieties to year-round availability of domestic and imported Hass avocados. California avocado producers, who account for approximately 90% of U.S. avocado production and essentially all U.S. Hass avocado production, have funded promotional programs for avocados since 1961. With few imports of avocados prior to the early 1990s, the benefits from these demand-enhancing programs flowed directly to California producers. Imports of avocados into the United States have increased steadily since then, resulting in a free-rider problem that led ultimately to creation of the Hass Avocado Promotion, Research, and Information Act of 2000. This act established the authorizing platform and timetable for creation of the Hass Avocado Promotion, Research, and Information Order (HAPRIO), which was approved in 2002. This study evaluates the promotion activities conducted by the Hass Avocado Board (HAB) during its first five years of operation. The report discusses the major marketing programs conducted under the auspices of HAB, provides an overview of trends in U.S. consumption of avocados, and contains a detailed analysis of annual demand for avocados in the United States with the goal of determining the impact that promotions have had on avocado demand. The report introduces and implements a simulation framework to estimate the impact of avocado promotion on grower prices and incomes and on consumption of avocados based on the results of the demand analysis. It provides an analysis of avocado demand and the impact of promotion based on retail scanner data, and presents the analysis of the impacts of HAB’s information-sharing and dissemination program.
