Percentage signal recovery plus relative cerebral blood volume: a practical dual-parameter strategy for differentiating post-stereotactic radiosurgery tumour progression from radiation necrosis in brain metastases [PDF]

open access: yesInsights into Imaging
Objectives Stereotactic radiosurgery (SRS) is widely used for brain metastases, but differentiating tumour progression from radiation necrosis on conventional MRI remains difficult.

Localizing Violations of the Principle of Sufficient Reason—Leibniz on the Modal Status of the PSR

open access: yesJournal of Modern Philosophy, 2022
The Principle of Sufficient Reason (PSR)—the principle that everything has a reason—plays a central role in Leibniz’s philosophical system. It is rather difficult, however, to determine what Leibniz’s attitude towards the modal status of the PSR is.

Multifrequency study of the peculiar pulsars PSR B0919+06 and PSR B1859+07 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Since their discovery more than 50 years ago, broad-band radio studies of pulsars have generated a wealth of information about the underlying physics of radio emission. In order to gain some further insights into this elusive emission mechanism, we performed a multifrequency study of two very well-known pulsars, PSR B0919+06 and

PSR: polymorphic SSR retrieval [PDF]

open access: yesBMC Research Notes, 2015
With the advent of high-throughput sequencing technologies large-scale identification of microsatellites became affordable and was especially directed to non-model species. By contrast, few efforts have been published toward the automatic identification of polymorphic microsatellites by exploiting sequence redundancy.
