Extension of an Exponential Light Curve GRB Pulse Model Across Energy Bands
, 2011 A simple mathematical model of GRB pulses in time, suggested in Norris et al. (2005), is extended across energy. For a class of isolated pulses, two of those parameters appear effectively independent of energy.

Superluminal optical pulse propagation in nonlinear coherent media [PDF]
, 2002 The propagation of light-pulse with negative group-velocity in a nonlinear medium is studied theoretically. We show that the necessary conditions for these effects to be observable are realized in a three-level $\Lambda$-system interacting with a ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Speciesism, Subjectivity, and Becoming-Other in Michel Faber’s Novel Under the Skin
Pulse, 2023 This paper undertakes a critical analysis of Michel Faber’s novel, Under the Skin (2000), with the aim to explore ethical relations between different species.

Optics Letters, 2014 We demonstrate the use of coherent division and recombination of the pulse within an ultrafast laser cavity to manage the nonlinear phase accumulation and scale the output pulse energy. We implement the divided-pulse technique in an ytterbium-doped fiber laser and achieve 16 times scaling of the pulse energy, to generate 6 nJ and 1.4 ps solitons in ...

Gamma-Ray Burst Pulse Shapes: Evidence for Embedded Shock Signatures?
, 2014 A study of a set of well-isolated pulses in Long and Intermediate gamma ray burst light curves indicates that simple pulse models having smooth and monotonic pulse rise and decay regions are inadequate.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

(AI)sland Ecologies: Toward New Metaphors and Models of Artificial Intelligence
Pulse, 2023 This article examines the application of ecological metaphors to socio-technical systems. This is a long and contested tradition that has often been critiqued for misapplying biological principles to the understanding of socio-technical systems.

Nonlinear transmission lines for pulse shaping in silicon [PDF]
, 2005 Nonlinear transmission lines (NLTL) are used for pulse shaping. We developed the theory of pulse propagation through the NLTL. The problem of a wide pulse degenerating into multiple pulses rather than a single pulse is solved by using a gradually scaled ...
