description: Background: We have reported that BRAF V600E mutations and microsatellite instability-high (MSI-H) are more prevalent in a population-based cohort of metastatic colorectal cancer (mCRC) patients than has been reported from clinical trials or hospital-based patient groups. The aim was to explore if other mutations in mCRC differ in prevalence between these cohorts in relation to mismatch repair status and primary tumor location and if presence of bone or brain metastases is associated with any mutations. Material and methods: A population-based cohort of 798 mCRC patients from three regions in Scandinavia was used. Forty-four cancer related genes were investigated in a custom designed Ampliseq hotspot panel. Differences in survival were analyzed using the Kaplan–Meier estimator and the Cox regression analysis. Results: Determination of mutations was possible in 449/501 patients for 40/44 genes. Besides BRAF V600E, seen in 19% of the tumors, none of the other mutations appeared more prevalent than in trial cohorts. BRAF V600E and MSI-H, seen in 8%, were associated with poor prognosis as was right-sided primary tumor location (39%) when compared to left-sided and rectum together; however, in a multivariable regression, only the BRAF mutation retained its statistical significance. No other mutations were associated with poor prognosis. ERBB2 alterations were more common if bone metastases were present at diagnosis (17% vs. 4%, p = .011). No association was found for brain metastases. Fifty-two percent had an alteration that is treatable with an FDA-approved targeted therapy, chiefly by EGFR-inhibitor for RAS wild-type and a check-point inhibitor for MSI-H tumors. Conclusions: Right-sided tumor location, BRAF V600E mutations, but no other investigated mutation, and MSI-H are more commonly seen in an unselected cohort than is reported from clinical patient cohorts, likely because they indicate poor prognosis. Half of the patients have a tumor that is treatable with an already FDA-approved targeted drug for mCRC.

description: The inter-sectoral migration of agricultural labour is a complex but fundamental process of economic development largely affected by the growth of agricultural productivity and the evolution of the agricultural relative income gap. Theory and some recent anecdotal evidence suggest that as an effect of large fixed and sunk costs of out-farm migration, the productivity gap between the agricultural and non-agricultural sectors should behave non-monotonically or following a U-shaped evolution during economic development. Whether or not this relationship holds true across a sample of 38 developing and developed countries and across more than 200 EU regions was empirically tested. Results strongly confirm this relationship, which also emphasises the role played by national agricultural policy.
A density functional theory study of electric potential saturation: planar geometry

Year: 2003
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We investigate the possibility of electrostatic potential saturation, which may lead to the phenomenon of effective charge saturation. The system under study is a uniformly charged infinite plane immersed in an arbitrary electrolyte made up of several micro-species. To describe the electric double layer, we use a generic density functional theory in which the local micro-ionic density profiles are arbitrary functions of the local electrostatic potential. A necessary and sufficient condition is obtained for saturation, whereby the electrostatic potential created by the plane becomes independent of its bare charge, provided the latter is large enough.

description: Dispersal of Sedum tosaense between Japan and Korea
 Jeju Island was formed by volcanic activity, which started ~2.0 million years ago (Ma), and by repeated connections and separations to/from the Eurasian Continent (Woo et al. 2013). Recent biostratigraphic analyses indicate that the Eurasian Continent, including the Korean peninsula and Jeju Island, was connected to the Japanese mainland by a land-bridge that flooded 3.5–1.7 Ma, leading to the formation of the present-day Tsushima Strait (Kitamura & Kimoto 2006). Our molecular analysis indicated that the populations of S. tosaense in Kochi and on Jeju populations diverged ~0.61 (1.37–0.07) Ma. Therefore, divergence must have occurred much later than the formation of the Tsushima Strait. It is more likely that S. tosaense crossed the water body presently separating the two populations. Some Sedum species have migrated to ocean islands; for example, S. boninense Yamamoto ex Tuyama (1936: 428) occurs on the Bonin Islands, Japan (Tsuyama, 1936) and S. formosanum N.E. Br. (1885: 134) occurs on Lanyu Island, Taiwan (Tang & Huang, 1993). Presently, no relevant morphological data on the fruits and seeds of S. tosaense suggests a mechanism that would allow the crossing. These data are required to test any putative mechanisms for dispersal across the strait.

Remarks. Singapore is listed as part of the distribution for B. multomaculata by David & Vogel (1996) and Cox et al. (1998), but we are unsure where they acquired the record from as no publications exist reporting B. multomaculata from Singapore. Perhaps they are alluding to Cantor (1847b) who said B. multomaculata occurs in Peninsular Malaysia, but Smith(1930) explained that this was incorrect.Clearly there is discrepancy surrounding the distribution of B. multomaculata as it also does not occur in Peninsular Malaysia (E.S.H. Quah pers. comm.), Borneo (Stuebing et al. 2014), nor Sulawesi (de Lang & Vogel 2005). Furthermore, Das (2010) did not list it as occurring in Indonesia, although it is known from Sumatra (David & Vogel 1996), Java, and Bali (de Lang 2017).

description: Modern technologies are often not widely adopted among smallholder farmers in Sub-Saharan Africa. Several adoption constraints have been discussed in the literature, including limited access to information. Using survey data from farmers in Tanzania and the average treatment effect framework, we question the hypothesis that limited information is an important constraint for the adoption of hybrid maize technology. While we find an adoption gap from incomplete awareness exposure, this gap is sizeable only in the east of Tanzania, where productivity effects of hybrids are small. In the north, where adoption is much more beneficial, almost all farmers are already aware of hybrids. The results suggest that exposure to a new technology may be a function of expected returns to adoption. We also test for other constraints related to credit and risk, which do not determine adoption significantly. More generally, nonadoption of technologies is not always a sign of constraints but may also indicate low benefits. Some policy implications are discussed.

description: Motivated by the recently observed insulating states in twisted bilayer graphene, we study the nature of the correlated insulating phases of the twisted bilayer graphene at commensurate filling fractions. We use the continuum model and project the Coulomb interaction onto the flat bands to study the ground states by using a Hartree-Fock approximation. In the absence of the hexagonal boron nitride substrate, the ground states are the intervalley coherence states at charge neutrality (filling $ν$ = 0, or four electrons per moiré cell) and at $ν$ = -1/4 and -1/2 (three and two electrons per cell, respectively) and the $C_2\mathcal{T}$ symmetry-broken state at $ν$= -3/4 (one electron per cell). The hexagonal boron nitride substrate drives the ground states at all $ν$ into $C_2\mathcal{T}$ symmetry broken-states. Our results provide good reference points for further study of the rich correlated physics in the twisted bilayer graphene.

For a range of values of the coupling to the topological term $θ$ and the gauge coupling $β$ we compare with results from hybrid Monte Carlo when possible and find good agreement.

Feature Engineering (FE) focuses on optimizing data for ML models, with evolutionary methods being effective in feature selection and construction tasks. This work aims to benchmark an evolutionary FE wrapper, using models based on decision trees as proxies. The FEDORA framework is applied to a Hearing Loss (HL) dataset, being able to reduce data dimensionality and statistically maintain baseline performance. Compared to traditional methods, FEDORA demonstrates superior performance, with a maximum balanced accuracy of 76.2%, using 57 features. The framework also generated an individual that achieved 72.8% balanced accuracy using a single feature.

description: A new model, based on the BCS approach, is specially designed to describe nuclear phenomena $(A,Z)\rightarrow (A,Z\pm 2)$ of double-charge exchange (DCE). After being proposed, and applied in the particle-hole limit, by one of the authors (F. Krmpotić [1]), so far it was never been applied within the BCS mean-field framework, nor has its ability to describe DCE processes been thoroughly explored. It is a natural extension of the pn-QRPA model, developed by Halbleib and Sorensen [2] to describe the single $β$-decays $(A,Z)\rightarrow (A,Z\pm 1)$, to the DCE processes. As such, it exhibits several advantages over the pn-QRPA model when is used in the evaluation of the double beta decay (DBD) rates. For instance, i) the extreme sensitivity of the nuclear matrix elements (NMEs) on the model parametrization does not occur, ii) it allows to study NMEs, not only for the fundamental state in daughter nuclei, as the pn-QRPA model does, but also for all final $0^+$ and $2^+$ states, accounting at the same time their excitation energies and the corresponding DBD Q-values, iii) together with the DBD-NMEs it provides also the energy spectra of Fermi and Gamow-Teller DCE transition strengths, as well as the locations of the corresponding resonances and their sum rules, iv) the latter are relevant for both the DBD and the DCE reactions, since the involved nuclear structure is the same; this correlation does not exist within the pn-QRPA model. As an example, detailed numerical calculations are presented for the $(A,Z)\rightarrow (A,Z+ 2)$ process in $^{48}$Ca $\rightarrow ^{48}$Ti and the $(A,Z)\rightarrow (A,Z- 2)$ process in $^{96}$Ru $\rightarrow ^{96}$Mo, involving all final $0^+$ states and $2^+$ states.

A Policy Perspective on Coconut Processing in the South Pacific Islands

description: For many island nations of the South Pacific the coconut palm is the most important smallholder tree crop. Most attempts to introduce processing beyond the copra stage have failed. At the same time there is a declining trend in copra prices. Unlike most other major coconut production countries (Philippines, India, Indonesia, Sri Lanka, and Thailand), the South Pacific nations do not hav a significant expanding domestic urban markets. As a result they must look to alternative export markets and direct output to higher income, non-traditional market niches. This paper, part of an on-going research project, presents arguments in favour of an export 'demand-pull' strategy for the coconut industry based on a re-examination of the coconut as a total resource rather than only as a source of a raw vegetable oil. The effective use of this resource requires that the fruit be processed as a mature fresh nut and that all parts of the nut are used. The strategy implies a switch in research priorities, away from plant breeding and disease control towards processing, domestic and international shipping, energy policies and market development. Improved markets would in turn give renewed impetus to the continuarion of the the excellent plant breeding work that has already been done.

This paper reports on a ten year plant density trial undertaken by the Tea Research Institute in Hangzhou, Zhojiang Province. The green tea, vegetatively propagated, clonal variety used in the trial is called "Longjing 43". At the high densities used, this variety has yields more than ten times greater than the average for Zhejiang Province. Four different plant density levels were used in the trial. The economic analysis examines the performance in terms of conventional investment criteria: SNPV, Perpetual Annuity, B/C ratio, IRR and the Discounted payback period. The optimum time to prune is also calculated for each of the trials and sensitivity analyses are undertaken using various assumptions as to the relative performance farmers might attain.

description: The black hole entropy calculation for type I isolated horizons, based on loop quantum gravity, is extended to include non-minimally coupled scalar fields. Although the non-minimal coupling significantly modifies quantum geometry, the highly non-trivial consistency checks for the emergence of a coherent description of the quantum horizon continue to be met. The resulting expression of black hole entropy now depends also on the scalar field precisely in the fashion predicted by the first law in the classical theory (with the same value of the Barbero-Immirzi parameter as in the case of minimal coupling).

description: This study used eye-tracking to capture the students' visual attention while taking the test of understanding graphs in kinematics (TUG-K). A total of N = 115 upper-secondary-level students from Germany and Switzerland took the 26-item multiple-choice instrument after learning about kinematics graphs in the regular classroom. Besides choosing the correct alternative among research-based distractors, the students were required to judge their response confidence for each question. The items were presented sequentially on a computer screen equipped with a remote eye tracker, resulting in a set of approx. 3000 paired responses (accuracy and confidence) and about 40 hours of eye movementdata (approx. 500.000 fixations). The analysis of students' visual attention related to the item stems (questions) and the item options reveal that high response confidence is correlated with shorter visit duration on both elements of the items. While the students' response accuracy and their response confidence are highly correlated on the score level, r(115) = 0.63, p < 0.001, the eye-tracking measures do not sufficiently discriminate between correct and incorrect responses. However, a more fine-grained analysis of visual attention based on different answer options reveals a significant discrimination between correct and incorrect answers in terms of an interaction effect: Incorrect responses are associated with longer visit durations on strong distractors and less time spent on correct options while correct responses show the opposite trend. Outcomes of this study provide new insights into the validation of concept inventories based on students' behavioural level.
Measuring the Higgs boson parity at a Linear Collider using the tau impact parameter and tau --> rho nu decay

description: We demonstrate that a measurement of the impact parameter in one-prong tau decay can be useful for the determination of the Higgs boson parity in the H/A --> tau tau; tau --> rho nu decay chain. We have estimated that for a detection set-up such as TESLA, use of the information from the tau impact parameter can improve the significance of the measurement of the parity of the Standard Model 120 GeV Higgs boson to 4.5 sigma, and in general by factor of about 1.5 with respect to the method where this information is not used. We also show that the variation in the assumption on the precision of the measurement of the impact parameter and/or pi's momenta does not affect the sensitivity of the method. This is because the method remains limited by the type of twofold ambiguity in reconstructing the tau momentum.

description: Photons propagating in a plasma acquire an effective mass $μ$, which is given by the plasma frequency and which scales with the square root of the plasma density. As noted previously by Conlon and Herdeiro, for electron number densities $n_e\sim 10^{-3}$ cm$^{-3}$ (such as those measured in the interstellar medium) the effective mass induced by the plasma is $μ\sim 10^{-12}$ eV. This would cause superradiant instabilities for spinning black holes of a few tens of solar masses. An obvious problem with this picture is that densities in the vicinity of black holes are much higher than in the interstellar medium because of accretion. We have conducted numerical simulations of the superradiant instability in spinning black holes surrounded by a plasma with density increasing closer to the black hole, in order to mimic the effect of accretion. While we confirm that superradiant instabilities appear for plasma densities that are sufficiently low near the black hole, we find that astrophysically realistic accretion disks are unlikely to trigger such instabilities.

Measuring Polynomial Invariants of Multi-Party Quantum States

description: We present networks for directly estimating the polynomial invariants of multi-party quantum states under local transformations. The structure of these networks is closely related to the structure of the invariants themselves and this lends a physical interpretation to these otherwise abstract mathematical quantities. Specifically, our networks estimate the invariants under local unitary (LU) transformations and under stochastic local operations and classical communication (SLOCC). Our networks can estimate the LU invariants for multi-party states, where each party can have a Hilbert space of arbitrary dimension and the SLOCC invariants for multi-qubit states. We analyze the statistical efficiency of our networks compared to methods based on estimating the state coefficients and calculating the invariants.

Cavanilles (1793) described this species from the Sagunto area of Spain (“Habitat in Saguntinae arcis vetustissimo muro”). The iconography is original material for the name and perfectly depicts all of the morphological details of this species. I was not able to trace further original materials. For this reason the iconography is selected as the lectotype. The lectotype confirms the current application of the name (e.g. Chater & Cartier 1976, Pignatti 1982).

description: We investigate the effect of sliding motion of layers in Moiré heterostructures on the electronic state. We show that the sliding Moiré heterostructure can generate nontrivial topology characterized by the first and second Chern number in the high dimensional manifold spanned by the physical dimensions and synthetic dimensions associated with the sliding displacement. The nontrivial topology implies a topological charge pumping caused by the sliding motion. We demonstrate the nontrivial topology and charge pumping explicitly in a one dimensional bi-chain model and the small-angle twisted bilayer graphene. Contrary to the conventional belief that the interlayer sliding in incommensurate Moiré Heterostructures does not affect the electronic structure, our results reveal that the sliding motion can generate nontrivial topology dynamically and hence cannot be neglected in the dynamical process.

description: The aim of this study is to investigate the direct and indirect impacts of sugarcane expansion on deforestation in the Brazilian Amazon from 2001 to 2008. The analysis is based on the multi-output production theory where the annual agricultural acreage represents the Production Possibility Frontier. It assumes that agricultural area is limited and any agricultural expansion occurs over traditional agricultural areas displacing some crops and pushing them to the agricultural frontier, where forests will be cleared. The econometric analysis was carried out using a panel data model where the counties are the cross section unity. The output supply for São Paulo state and the agricultural frontier states (Mato Grosso, Rondônia, Maranhão and Tocantins) in the Center-West region are estimated separately, considering the acreage as proxy of the output and the crop prices of sugarcane, soybean, corn, beans, cotton and the total annual acreage as the independent variables. The impact of crop prices and the annual agricultural crop expansion over the deforestation acreage are also estimated. Our best estimates reveal that it is not possible to establish a direct connection between sugarcane area expansion and Amazon deforestation, and while the indirect effects are very small, sugarcane also expanded over pastures and perennial crops, leading to an overall increase in annual crop area.

description: When prior partial information about a state to be cloned is available, it can be cloned with a fidelity higher than that of universal quantum cloning. We experimentally verify this intriguing relationship between the cloning fidelity and the prior information by reporting the first experimental optimal quantum state-dependent cloning, using nuclear magnetic resonance techniques. Our experiments may further have important implications into many quantum information processing protocols.
