Research Notes : Relay intercropping of soybeans and small grains

During the past two years we have been comparing several cropping systems: relay intercropping of soybeans with wheat, relay intercropping of soybeans with oats, and soybean monoculture. The purpose of the study was to determine if a need for separate breeding programs for these specialized cultural practices exists . Last year McBroom et al. (1979) reported a significant cultivar x cropping system interaction that would seem to indicate that such a need did exist

Research notes: Relay cropping of soybeans and oats

One possibility of increasing land productivity in Illinois is to double crop soybeans following wheat. This practice has been limited to the southern half of the state because of the shorter growing season in the northern half. A modification of double cropping known as relay cropping might allow the earlier establishment of soybeans in wheat or oats and extend the northern limit of double cropping in the state

Entangling interactions between artificial atoms mediated by a multimode left-handed superconducting ring resonator

Superconducting metamaterial transmission lines implemented with lumped circuit elements can exhibit left-handed dispersion, where the group and phase velocity have opposite sign, in a frequency range relevant for superconducting artificial atoms. Forming such a metamaterial transmission line into a ring and coupling it to qubits at different points around the ring results in a multimode bus resonator with a compact footprint. Using flux-tunable qubits, we characterize and theoretically model the variation in the coupling strength between the two qubits and each of the ring resonator modes. Although the qubits have negligible direct coupling between them, their interactions with the multimode ring resonator result in both a transverse exchange coupling and a higher order $ZZ$ interaction between the qubits. As we vary the detuning between the qubits and their frequency relative to the ring resonator modes, we observe significant variations in both of these inter-qubit interactions, including zero crossings and changes of sign. The ability to modulate interaction terms such as the $ZZ$ scale between zero and large values for small changes in qubit frequency provides a promising pathway for implementing entangling gates in a system capable of hosting many qubits.Comment: 8 + 11 pages, 5 + 5 figures, 0 + 3 table

Primary appendiceal mucinous adenocarcinoma in two first-degree relatives: case report and review

Carcinomas of the appendix are exceedingly rare tumors and have an annual age-adjusted incidence of around 0.4 cases per 100,000. Appendiceal adenocarcinoma accounts for < 0.5% of all gastrointestinal neoplasms and, of these, mucinous adenocarcinomas account for the majority. Published accounts of familial instances of primary appendiceal tumors are strikingly rare. We report two siblings who both developed primary mucinous adenocarcinomas. A genetics evaluation was conducted to determine if there was a recognizable underlying single gene disorder; no DNA mismatch repair defect was evident, and no other diagnosis was apparent. A review of appendiceal cancers seen at Mayo Clinic from l997 to the present was conducted to search for additional familial cases. Among 316 cases of primary appendiceal cancer of any histologic type, this sib pair was the only family reporting a second affected family member. The occurrence of appendiceal cancer in siblings may represent a random occurrence. An exceedingly rare predisposition syndrome cannot be ruled out

Encouraging developing country involvement in a post-2012 climate change regime: carrots, sticks or both?

The climate-trade nexus has become the focus of academic debate, and has gained increasing attention as governments are taking great efforts to forge a post-2012 climate change regime to succeed the Kyoto Protocol. With concerns about their own competitiveness and growing greenhouse gas emissions in developing countries, some industrialized countries, if not all, are considering whether to impose unilateral trade measures against developing country trading partners. While it is clear that greenhouse gas emissions targets of developed countries need to be tightened further in a post-2012 climate change regime, developing country involvement is also crucial for climate change mitigation and adaptation, given that climate change is a global problem requiring a global response. This raises the issue of which approach would be most likely to stimulate developing countries to take appropriate actions in the post-2012 climate regime. Would positive or negative incentives work best, in other words, do we need carrots, sticks or both? This paper seeks to answer this question. By revisiting the six options for China that I envisioned a decade ago and examining a variety of factors, the paper first discusses how far developing country commitments can go in an immediate post-2012 climate regime. It argues that developing country commitments are most unlikely to go beyond defined policies and measures in this timeframe. The type of border adjustment provisions currently being discussed by most developed countries include more sticks than carrots for developing countries. Sticks can be incorporated, but only if they are credible and realistic and serve as a useful supplement to push developing countries to take actions or adopt policies and measures earlier than would otherwise have been the case. In order to encourage developing countries to do more to combat climate change, the paper suggests that developed countries should rather focus on carrots

Homozygous staggerer (sg/sg) mice display improved insulin sensitivity and enhanced glucose uptake in skeletal muscle

Homozygous staggerer (sg/sg) mice, which have decreased and dysfunctional Ror alpha (also known as Rora) expression in all tissues, display a lean and dyslipidaemic phenotype. They are also resistant to (high fat) diet-induced obesity. We explored whether retinoic acid receptor-related orphan receptor (ROR) alpha action in skeletal muscle was involved in the regulation of glucose metabolism
