Web9 Aug 2024 · A male orca can be nearly ten metres in length and weight 10,000kg. Orcas are highly intelligent and able to coordinate hunting tactics. Female orcas are thought to live to 80 years of age or more. The dorsal fin of a male orca is up to two metres tall. Orcas are extremely fast swimmers and have been recorded at speeds of up to 54kph.

WebA thick layer of fat, or blubber, helps an orca stay warm even in icy waters. A baby orca, or calf, is usually born tail-first. It weighs about 400 pounds (180 kilograms). Female orcas tend to live longer than males. Females can live to be 90 years old; males live about 50 years. An orca's only enemy is people. Web5 Nov 2024 · The rate of moderate to severe chronic GVHD for Orca-T patients was 4% vs. 44% in the SoC cohort (p=0.016). In a preliminary subset of evaluable Orca- T patients, GVHD & relapse free survival (GRFS) at one year was higher for Orca-T patients vs SoC (69% versus 33%, p=0.006) while relapse and overall survival did not appear to differ.

WebThere are two main possibilities how to evoke a MD simulation. With the flag --omd geometry optimization will be performed and this structure then will be used for the MD simulation, a loose optimization level will be chosen. > xtb coord --omd. By using the flag --md the MD simulation will be performed directly with the user given input structure.
Using the ROCIS module one can perform configuration interaction single excitation calculations using either a restricted open-shell reference (ROHF) or a RHF (for closed-shell, equivalent to using the CIS module) or UHF reference (will use QRO orbitals). ! def2-SVP TightSCF%rocis NRoots 2MaxDim 5end * xyz … See more It is sometimes possible to guide SCF calculations (HF or DFT) to an excited state solution of the same multiplicity (to find the first excited state of a different … See more See also the ROCIS module below.
