RESUMO
Circuit depth reduction is of critical importance for quantum chemistry simulations on current and near term quantum computers. This issue is tackled by introducing a chemically aware strategy for the unitary coupled cluster ansatz. The objective is to use the chemical description of a system to aid in the synthesis of a quantum circuit. We combine this approach with two flavors of symmetry verification for the reduction of experimental noise. These methods enable the use of Quantinuum's System Model H1 ion trap quantum computer for a 6-qubit quantum subspace expansion calculation. We present (i) calculations to obtain methane's optical spectra; (ii) an atmospheric gas reaction simulation involving [CH3â -H-OH]. Using our chemically aware unitary coupled cluster state-preparation strategy in tandem with state of the art symmetry verification methods, we improve device yield for CH4 at 6 qubits. This is demonstrated by a 90% improvement in two-qubit gate count and a reduction in relative error to 0.2% for electronic energy calculated on System Model H1.
RESUMO
Constipation is a frequent cause of distress in advanced cancer. A palliative care unit in Kerala, a southern state of India, conducted a controlled trial comparing a liquid Ayurvedic (herbal) preparation (Misrakasneham) with a conventional laxative tablet (Sofsena) in the management of opioid-induced constipation in patients with advanced cancer. Although there was no statistically significant difference in the apparent degree of laxative action between the two, the results indicate that the small volume of the drug required for effective laxative action, the tolerable taste, the once-daily dose, the acceptable side effect profile, and the low cost make Misrakasneham a good choice for prophylaxis in opioid-induced constipation. There is a need for further studies of Ayurvedic medicines in palliative care.

Filariasis is known to medical science over many centuries. It is a disease of tropical countries due to the presence of microfilaria. The effected areas are large and elephantoid in appearance, so it is called 'Elephantiasis'. A non-parasitic form of Elephantiasis occurs when the lymphatics are blocked. In Ayurveda this disease is termed as Shlipada.

JARA VYADHI or senility is caused by onset of the deterioration of cell structure in the body. Though this situation is unavoidable, Ayurveda shows a way for lengthening the onset of senility. This paper gives the precise aspects of the management of this condition according to the texts.
