description: The government of Ethiopia implemented a 150 percent export tax on raw hides and skin and semi-finished leather products and crust leather in 2008 and 2012 respectively, in order to encourage leather manufacturing industry. The objective of this paper is to analyse the effect of export tax on Ethiopia’s leather industry export competitiveness. Constant Market Share (CMS) model has been used to evaluate Ethiopian’s performance in leather product trade. Export value data in 2007 was used as a base year, whereas data in 2013 was considered as a year after export tax. The results indicated that, implementation of export tax shifted the export of hides and skins and unfinished leather product to finished leather product. Besides the shift in export products from raw materials to finished leather product, implementation of export tax has also resulted in positive export growth (2.55. this indicate that,the country’s leather product export growth was higher than world demand after implementation of export tax; which is most likely achieved by an increase in export competitiveness of the leather industry (2.25).

description: The least-squares method was firmly established as a scientific approach by Gauss, Legendre and Laplace within the space of a decade, at the beginning of the nineteenth century. Legendre was the first author to name the approach, in 1805, as “méthode des moindres carrés,” a “least-squares method.” Gauss, however, is credited to have used it as early as 1795, when he was 18 years old. He, subsequently, adopted it in 1801 to calculate the orbit of the newly discovered planet Ceres. Gauss published his way of looking at the least-squares approach in 1809 and gave several hints that the least-squares algorithm was a minimum variance linear estimator and that it was derivable from maximum likelihood considerations. Laplace wrote a very substantial chapter about the method in his fundamental treatise on probability theory published in 1812. Surprisingly, there still remains an unexplored aspect of the least-squares method: since the traditional formulation is stated as minimizing the sum of squared deviations subject to the linear (or nonlinear) specification of a regression model, this mathematical programming problem must have a dual counterpart. This note fills this gap and shows that the least-squares estimates of unknown parameters and deviations can be obtained by maximizing the net value of sample information.

description: We obtain exact analytic expressions for (i) the electromagnetic energy radial density within and outside a multilayered sphere and (ii) the total electromagnetic energy stored within its core and each of its shells. Explicit expressions for the special cases of lossless core and shell are also provided. The general solution is based on compact recursive transfer-matrix method and its validity includes also magnetic media. The theory is illustrated on the examples of electric field enhancement within various metallo-dielectric silica-gold multilayered spheres. User-friendly MATLAB code which includes the theoretical treatment, is available as a supplement to the paper.

Dissipation-assisted quantum gates with cold trapped ions

description: It is shown that a two-qubit phase gate and SWAP operation between ground states of cold trapped ions can be realised in one step by simultaneously applying two laser fields. Cooling during gate operations is possible without perturbing the computation and the scheme does not require a second ion species for sympathetic cooling. On the contrary, the cooling lasers even stabilise the desired time evolution of the system. This affords gate operation times of nearly the same order of magnitude as the inverse coupling constant of the ions to a common vibrational mode.

description: Spatial point tracks are of concern for an increasing number of analysts studying spatial behaviour patterns and environmental effects. Take an epidemiologist studying the behaviour of cyclists and how their health is affected by the city’s air quality. The accuracy of such analyses critically depends on the positional accuracy of the tracked points. This poses a serious privacy risk. Tracks easily reveal a person’s identity since the places visited function as fingerprints. Current obfuscation-based privacy protection methods, however, mostly rely on point quality reduction, such as spatial cloaking, grid masking or random noise, and thus render an obfuscated track less useful for exposure assessment. We introduce simulated crowding as a point quality preserving obfuscation principle that is based on adding fake points. We suggest two crowding strategies based on extending and masking a track to defend against inference attacks. We test them across various attack strategies and compare them to state-of-the-art obfuscation techniques both in terms of information loss and attack resilience. Results indicate that simulated crowding provides high resilience against home attacks under constantly low information loss.

description: After several years of informal and formal negotiations, South Korea and the United States reached an agreement to move towards free trade in April 2007. Currently, both countries await congressional approval before the agreement can be implemented. This study explains the substance of the agricultural parts of the agreement and considers its agricultural implications. The study finds that the Korea-United States Free Trade Agreement has the potential to be a significant demand driver for many sectors within California agriculture. Despite its high import tariffs, tight import quota quantities and restrictive sanitary and phytosanitary regulations, South Korea has become a major agricultural importer from California. South Korea is an important export destination for a broad array of California agricultural products and has recently ranked among the top five or six export destinations for California agriculture. The agreement provides for gradual elimination of Korea’s high tariffs for most California export products, with the exception of rice, where a previously negotiated quota would remain and fresh citrus where high seasonal tariffs would continue to limit shipments of oranges and mandarins. With lower import barriers there is significant potential for expanding California agricultural exports to Korea in for important commodities from dairy products to tree nuts. This study catalogs current agricultural exports to Korea from California, reviews the existing trade barriers that limit exports to Korea, considers explicitly the export positions of major competitors and examines the size of the Korean market for each important commodity and commodity group. The study’s insight on the potential effects of the Agreement will help California agriculture better appreciate and communicate what is at stake for California agriculture and prepare for the realistic impacts of the potential market opening in Korea.

description: The emergence of carbapenem-resistant Escherichia coli (CREC) poses crucial challenges in clinical management, requiring continuous monitoring to inform control and treatment strategies. This study aimed to investigate the genomic and epidemiological characteristics of CREC isolates obtained from a tertiary hospital in China between 2015 and 2022. Next-generation sequencing was used for genomic profiling, and clinical data from patients were integrated into the analysis. ST405 (21.2%), ST167 (20.3%) and ST410 (15.9%) were the most prevalent of the 30 distinct sequence types (STs) identified among the 113 unique CREC isolates. Infections caused by the ST405 CREC clone and severe underlying diseases were associated with higher in-hospital mortality rates, particularly in patients aged ≥65 years. Furthermore, the ST405 clone exhibited a greater number of virulence and resistance genes than non-ST405 CREC clones. The virulence gene eaeX and resistance genes mph(E) and msr(E) were exclusively found in ST405 clones, while other virulence genes (agn43, ipad and malX) and resistance genes (armA, catB3 and arr-3) were more prevalent in this clones. Additionally, ST405 showed higher minimum inhibitory concentrations for both meropenem and imipenem and showed superior growth under the meropenem challenge. Galleria mellonella virulence assays revealed that the ST405 CREC clone was more virulent than other predominant CREC STs. Our findings underscore the clinical threat posed by the ST405 CREC clone, which exhibits both enhanced virulence and extensive drug resistance. These results highlight the urgent need for stringent surveillance and targeted interventions to curb its further dissemination and prevent potential outbreaks.

description: The Knowledge Discovery from Database (KDD) is an interactive and iterative process of analysis of a big quantity of data to extract knowledge from it that can be exploitable. Big databases such as pipeline inspection databases become potentially rich and reliable sources for the generation and the validation of knowledge. Data Mining constitutes the central step of process, and consists in applying algorithms of machine learning on data to extract hidden models. In this paper we propose to apply Datamining methods on pipeline databases to extract hidden models. Clustering K-means method is used to cluster pipeline ILI (In Line Inspection) data performed by instrumented pigs in a group of clusters. These clusters are interpreted in collaboration with business experts that the defects of each cluster have almost the same risk level. Then, two classifications methods (decision trees and neural network) are applied on clusters in order to construct a classification model of defects risk on pipe in three level (High, Medium and Low) according to their criticizes. The discovered models are evaluated using cross validation method, which allows choosing a model based on a decision tree as a pipeline defects risk classification and prediction model.
Solar models with convective overshoot, the solar-wind mass loss, and a PMS disk accretion: helioseismic quantities, Li depletion and neutrino fluxes

description: Helioseismic observations have revealed many properties of the Sun: the depth and the helium abundance of the convection zone, the sound-speed and the density profiles in the solar interior. Those constraints have been used to judge the stellar evolution theory. With the old solar composition (e.g., GS98), the solar standard model is in reasonable agreement with the helioseismic constraints. However, a solar model with revised composition (e.g., AGSS09) with low abundance $Z$ of heavy elements cannot be consistent with those constraints. This is the so-called "solar abundance problem", standing for more than ten years even with the recent upward revised Ne abundance. Many mechanisms have been proposed to mitigate the problem. However, there is still not a low-$Z$ solar model satisfying all helioseismic constraints. In this paper, we report a possible solution to the solar abundance problem. With some extra physical processes that are not included in the standard model, solar models can be significantly improved. Our new solar models with convective overshoot, the solar wind, and an early mass accretion show consistency with helioseismic constraints, the solar Li abundance, and observations of solar neutrino fluxes.

 Remarks. This nominal species has sometimes been combined with Clytia hemisphaerica (Linnaeus, 1767). Cornelius (1982) considered them identical, and a number of recent authors, including me (Calder, 1991; Cairns et al. 2002), adopted that opinion. After examining the material above, however, Clytia gigantea (Hincks, 1866) is upheld as a valid species based on a combination of characters including its strikingly robust colony form, sparingly branched pedicels, and exceptionally large, elongate, gradually tapered hydrothecae. Moreover, hydrothecal cusps in C. gigantea are linguiform (Fig. 46) rather than wavy as in C. hemisphaerica. Specimens studied here were much like those reported earlier from Bohuslän by Jaderholm (1909: pl. 7, figs. 1–3). In reporting the species from the Oslofjord, Norway, Christiansen (1972) noted that some hydrothecae in his material reached 3 mm long. Ones exceeding 2 mm in length were observed on the hydroid colony reported herein from Kosterhavet.
 Reports of Clytia gigantea from the Mediterranean, and from the Atlantic and Pacific coasts of North America (see below), need confirmation. The species, or a variant of it, has also been reported from Chile (Leloup 1974; Galea et al. 2009).
 Gonophores of this species, examined here (Fig. 47), are previously unknown in Europe. Those of the variant form from Chile have been described and illustrated by Leloup (1974) and Galea et al. (2009).
 Reported distribution. West coast of Sweden.—Bohuslän (Jäderholm 1909, as Campanularia gigantea).
 Elsewhere.—Boreal waters of the North Atlantic from Norway to Great Britain in Europe (Hincks 1868; Christiansen 1972), and from Newfoundland to Cape Cod in North America (Fraser 1944); questionable records exist from the Mediterranean (e.g., Pieper 1884; Babić 1904), the Queen Charlotte Islands in the northeast Pacific (Fraser 1937, as Campanularia gigantea), and Chile (Leloup 1974; Galea et al. 2009).

We look at two relevant phenomena: first, we analyze the stability of the Dirac vacuum with respect to particle/antiparticle pair production, both spontaneous and induced by an external electric field; then, we examine the string breaking mechanism. We observe a strong effect of confinement, which acts by suppressing both spontaneous pair production and string breaking into quark/antiquark pairs, indicating that the system dynamics displays a number of out-of-equilibrium features.

description: Multi-label multi-view action recognition aims to recognize multiple concurrent or sequential actions from untrimmed videos captured by multiple cameras. Existing work has focused on multi-view action recognition in a narrow area with strong labels available, where the onset and offset of each action are labeled at the frame-level. This study focuses on real-world scenarios where cameras are distributed to capture a wide-range area with only weak labels available at the video-level. We propose the method named Multi-view Action Selection Learning (MultiASL), which leverages action selection learning to enhance view fusion by selecting the most useful information from different viewpoints. The proposed method includes a Multi-view Spatial-Temporal Transformer video encoder to extract spatial and temporal features from multi-viewpoint videos. Action Selection Learning is employed at the frame-level, using pseudo ground-truth obtained from weak labels at the video-level, to identify the most relevant frames for action recognition. Experiments in a real-world office environment using the MM-Office dataset demonstrate the superior performance of the proposed method compared to existing methods.

description: Direct calculation of the one-loop contributions to the energy density of bosonic and supersymmetric phi-to-the-fourth kinks exhibits: (1) Local mode regularization. Requiring the mode density in the kink and the trivial sectors to be equal at each point in space yields the anomalous part of the energy density. (2) Phase space factorization. A striking position-momentum factorization for reflectionless potentials gives the non-anomalous energy density a simple relation to that for the bound state. For the supersymmetric kink, our expression for the energy density (both the anomalous and non-anomalous parts) agrees with the published central charge density, whose anomalous part we also compute directly by point-splitting regularization. Finally we show that, for a scalar field with arbitrary scalar background potential in one space dimension, point-splitting regularization implies local mode regularization of the Casimir energy density.
description: 18 pages. Numerous new clarifications and additions, of which the most important may be the direct derivation of local mode regularization from point-splitting regularization for the bosonic kink in 1+1 dimensions

description: Urban black holes and volcanoes are typical traffic anomalies that are useful for optimizing urban planning and maintaining public safety. It is still challenging to detect arbitrarily shaped urban black holes and volcanoes considering the network constraints with less prior knowledge. This study models urban black holes and volcanoes as bivariate spatial clusters and develops a network-constrained bivariate clustering method for detecting statistically significant urban black holes and volcanoes with irregular shapes. First, an edge-expansion strategy is proposed to construct the network-constrained neighborhoods without the time-consuming calculation of the network distance between each pair of objects. Then, a network-constrained spatial scan statistic is constructed to detect urban black holes and volcanoes, and a multidirectional optimization method is developed to identify arbitrarily shaped urban black holes and volcanoes. Finally, the statistical significance of multiscale urban black holes and volcanoes is evaluated using Monte Carlo simulation. The proposed method is compared with three state-of-the-art methods using both simulated data and Beijing taxicab spatial trajectory data. The comparison shows that the proposed method can detect urban black holes and volcanoes more accurately and completely and is useful for detecting spatiotemporal variations of traffic anomalies.

description: Mislabelling is a significant manifestation of food fraud. Traditional Sanger sequencing technology is the gold standard for seafood species identification. However, this method is not suitable for analysing processed samples that may contain more than one species. This study tested the feasibility of next-generation sequencing in identifying mixed salmon products. Salmon samples containing up to eight species were amplified using 16S rRNA mini-barcode primers, and sequenced on an Illumina HiSeq2500 platform. All species were accurately identified, and mixtures as low as 1% (w/w) could be detected. Furthermore, this study conducted a market survey of 32 products labelled as salmon. For pure and mixed fish products, Sanger and next-generation sequencing techniques were respectively used for species identification, and for NGS results, we also used real-time PCR method to cross-validate the mixed products to further verify the accuracy of the DNA metabarcoding technology established in this study. DNA barcoding and metabarcoding of commercial salmon food products revealed the presence of mislabelling in 16 of 32 (50%) samples. The developed DNA barcoding and metabarcoding methods are useful for the identification of salmon species in food and can be used for quality control of various types of salmon products.

COMMENT
Barbula ehrenbergii var. immersa Trab. ex Jelenc nom. inval. was proposed by Jelenc (1955a) from Sebdou. According to Ros et al. (2013), the identity of this name has not been revised since its description.
Barbula trabutii Jelenc nom. inval. descr. gall. was proposed by Jelenc (1955a) for the specimens collected and identified by Corbière as Didymodon trabutii Corb. ex Jelenc nom. inval., cited as a synonym, that was sent to Trabut and remained unpublished. Jelenc (1955a) indicated that this name could be just a local variation of Barbula ehrenbergii (synonym: Hydrogonium bolleanum). According to Ros et al. (2013), its identity has not been revised because the material has not been traced. The localities reported by Jelenc (1955a) were: Cascade du Khémis à Mazer, 1230 m; Monts de Tlemcen; Monts des Ksour, djebel Mekter au ravin de Aïn ed Diss Foukania, 1400 m.

description: California’s nursery and floral industry is the largest in the United States with a farm value for product sales totaling $3.78 billion in 2009. When floral and nursery product sales are combined, the industry ranks second among all California agricultural products, following the dairy industry. Production is in 55 of California’s 58 counties, although 16 counties account for more than 87% of the value of production. San Diego County dominates the industry with annual sales over $1 billion in 2007, 2008, and 2009. Since its 2008 and 2009 sales increased while California’s statewide sales decreased, San Diego County increased its share of California sales from 26% in 2007 to 30.3% in 2009. California is the largest single retail market for lawn and garden products in the United States, accounting for 7.6-10.4% of estimated total annual U.S. sales since 1997. Total 2009 California retail sales of lawn, garden, and floral products were estimated at more than $9.3 billion. The recession of 2008 and 2009 had a significant impact on retail sales and retail outlets. California florists’ sales plunged almost 62%, from a high of $1.2 billion in 2007 to $461 million in 2009. Farm and garden store sales also decreased 25.3% from 2007 to 2009. A regional economic model is used to trace the direct, indirect, and induced effects of California nursery and floral production and lawn and garden retailing through the California economy.

description: The effects of $Δ$ isobars on the equation of state of dense matter and structure of compact stars (CSs) are explored within the covariant density functional theory and confronted with the data on tidal deformability (TD) extracted from the GW170817 event. We show that the presence of $Δ$ isobars substantially softens the tension between the predictions of the hypernuclear density functionals and the inference from the observations of relatively small radius and small TD of canonical mass CSs. The TDs deduced from GW170817 are compatible with the existence of hypernuclear CSs containing an admixture of $Δ$ isobars. We thus argue that the GW170817 event is consistent with a merger of a binary CS system having both strangeness (hyperons) and $Δ$ isobars in the stellar core.

description: European bison (Bison bonasus), a flagship species for the burgeoning re-wildling movement, faced challenges common to large mammals globally. These include deforestation, land use conversion, poaching, and a lack of genetic diversity. Despite these limitations, organizations such as Rewilding Europe seek to reintroduce the species to its historic range. This study focused on finding suitable reintroduction locations for a population of at least 120 individuals. Through GIS-based multi-criteria decision-making using weighted linear combination and analytical hierarchy process, a model based on known bison habitat preferences, human-centered habitat constraints, and surface geography was used to identify regions large enough to accommodate a new herd. The study area included central-eastern Europe Union countries, specifically Germany, Poland, Lithuania, and Latvia. The model identified several highly suitable regions large enough to support a new herd, with the most optimal located in Poland. Highly suitable areas represented 2.7% of the study region. Relative isolation of suitable regions reinforced the challenges of promoting gene flow between reintroduced European bison herds. This model can be replicated in other conservation planning contexts, including reintroduction of large herbivores considering anthropogenic, ecological, and physical conditions.

description: Here we introduce a versatile stereolithographic route to produce three different kinds of Si-containing thermosets that yield high performance ceramics upon thermal treatment. Our approach is based on a fast and inexpensive thiol-ene free radical addition that can be applied for different classes of preceramic polymers with carbon-carbon double bonds. Due to the rapidity and efficiency of the thiol-ene click reactions, this additive manufacturing process can be effectively carried out using conventional light sources on benchtop printers. Through light initiated cross-linking, the liquid preceramic polymers transform into stable infusible thermosets that preserve their shape during the polymer-to-ceramic transformation. Through pyrolysis the thermosets transform into glassy ceramics with uniform shrinkage and high density. The obtained ceramic structures are nearly fully dense, have smooth surfaces, and are free from macroscopic voids and defects. A fabricated SiOC honeycomb was shown to exhibit a significantly higher compressive strength to weight ratio in comparison to other porous ceramics.

 Type locality. “Oceanus Europaeus” (Pallas 1766: 120).
 Museum material. Tjärnö, floating dock at Sven Lovén Centre for Marine Sciences, 58°52’33.68”N, 11°08’43.65”E, <1 m, 07.ix.2010, collected manually from dock, one colony, 9.5 cm high, without gonothecae, ROMIZ B3889.
 Remarks. The validity of Obelia longissima (Pallas, 1766) was confirmed by Östman (1982a, b, 1987, 1999), who showed that it differed from O. dichotoma (Linnaeus, 1758) in cnidome and in acid phosphatase band patterns. According to Cornelius (1990, 1995), O. longissima can be distinguished from O. dichotoma in having: (1) long, monosiphonic, regularly branched stems that are often dark or even black in colour; (2) branches over a given part of the stem of essentially the same length; (3) hydrothecae round instead of polygonal in cross-section; (4) hydrothecal margin with shallow, wavy cusps rather than a series of lobes. Nevertheless, young, old, or damaged specimens can still be difficult to identify based on morphology alone. The colonies examined here, rather old, somewhat damaged, and overgrown with other hydroids, corresponded most closely to O. longissima. Examination of nematocysts from tissue of museum material (ROMIZ B3889) revealed the presence of F l - type isorhizas (Fig. 55b, c), diagnostic of the species (Östman 1982b). A-type b-rhabdoids (microbasic b-mastigophores) were also present.
 A comprehensive overview of this species was given by Cornelius (1990). It is frequent in Danish waters (Kramp 1935b, as Laomedea longissima) and in the Oslofjord, Norway (Christiansen 1972), as well as western Sweden (Jägerskiöld 1971).
 Reported distribution. West coast of Sweden.—From Strömstad area to south of Falkenberg (Jägerskiöld 1971: 63).
 Elsewhere.—North Atlantic-Arctic from polar waters to the Mediterranean Sea in Europe, and to South Carolina in North America (Schuchert 2001a; Bouillon et al. 2004; Calder 2004).

description: The density profiles established in the self-similar dynamical phase of dark matter haloes recollapse are all close to isothermal. This is steeper than the predictions of some n-body simulations for the central regions of the halo, which are in turn steeper than the profiles observed in the centre of some galaxies; particularly dwarfs and low surface brightness galaxies. The outer regions of galaxies both as observed and as simulated have density profiles steeper than the self-similar profile. Nevertheless there appears to be an intermediate region in most galaxies in which the inverse square behaviour is a good description. The outer deviations can be explained plausibly in terms of the transition from a self-gravitating extended halo to a Keplerian flow onto a dominant central mass (the isothermal distribution can not be complete), but the inner deviations are more problematic. Rather than attack this question directly, we use in this paper a novel coarse-graining technique combined with a shell code to establish both the distribution function associated with the self-similar density profile and the nature of the possible deviations in the central regions. In spherical symmetry we find that both in the case of purely radial orbits and in the case of orbits with non-zero angular momentum the self-similar density profile should flatten progressively near the centre of the system. The NFW limit of -1 seems possible. In a section aimed at demonstrating our technique for a spherically symmetric steady state, we argue that a Gaussian distribution function is the best approximation near the centre of the system.
