Arecibo Timing and Single Pulse Observations of 18 Pulsars

, 2003
We present new results of timing and single pulse measurements for 18 radio pulsars discovered in 1993 - 1997 by the Penn State/NRL declination-strip survey conducted with the 305-m Arecibo telescope at 430 MHz.

The Double Pulsar System J0737-3039: Modulation of the radio emission from B by radiation from A [PDF]

, 2004
We have analyzed single pulses from PSR J0737-3039B, the 2.8-s pulsar in the recently discovered double pulsar system, using data taken with the Green Bank Telescope at 820 and 1400 MHz.

Leibniz on the PSR as a Regulative Principle of Rational Inquiry

Journal of Modern Philosophy
One of Leibniz’s fundamental philosophical commitments is the principle of sufficient reason (PSR). Yet Leibniz’s precise understanding of this principle is elusive.

ASCA Detection of Pulsed X-ray Emission from PSR J0631+1036 [PDF]

, 2001
ASCA's long look at the 288 millisecond radio pulsar, PSR J0631+1036, reveals coherent X-ray pulsation from this source for the first time. The source was first detected in the serendipitous Einstein observation and later identified as a radio pulsar ...

The position of PSR 0540-69

The Astrophysical Journal, 1994
Using time-resolved two-dimensional photon counting techniques we have found an accurate position for the X-ray and optical pulsar PSR 0540-69. Our position using postexposure variable aperture photometry confirms the position suggested by Caraveo et al.

Deficiency of RgpG causes major defects in cell division and biofilm formation, and deficiency of LytR-CpsAPsr family proteins leads to accumulation of cell wall antigens in culture medium by Streptococcus mutans [PDF]

, 2017
Streptococcus mutans is known to possess rhamnose-glucose polysaccharide (RGP), a major cell wall antigen. S. mutans strains deficient in rgpG , encoding the first enzyme of the RGP biosynthesis

Effect of process parameters on the strength of ABS based FDM prototypes: novel machine learning based hybrid optimization technique

Materials Research Express, 2023
Even though the prototypes built using Fused Deposition Modelling (FDM) process are found to exhibit good mechanical properties, there are ample scopes to improve them by means of selecting suitable process parameters. Since the FDM process involves more

Optical Detection of Two Intermediate Mass Binary Pulsar Companions

, 2006
We report the detection of probable optical counterparts for two Intermediate Mass Binary Pulsar (IMBP) systems, PSR J1528-3146 and PSR J1757-5322. Recent radio pulsar surveys have uncovered a handful of these systems with putative massive white dwarf ...
