Laser Illuminated Imaging: Beam and Scene Deconvolution Algorithm
, 2021 Laser illuminated imaging systems deal with several physical challenges that must be overcome to achieve high-resolution images of the target. Noise sources like background noise, photon counting noise, and laser speckle noise will all greatly affect the

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

With a Great Story Comes Great Responsibility: Role of Narrative in Leadership Development
New Directions for Student Leadership, Volume 2025, Issue 185, Page 81-87, Spring 2025.ABSTRACT Comic books reside uniquely within American culture. Historians have contended comics are more than just sequential artwork mixed with engaging stories, but rather, a framework by which the generations make sense of who they are. These stories are a reflection of cultural conscience; a lens through which we can view the world and a mirror ...

X‐ray fluorescence microscopy exposure estimates using a single excitation energy
Journal of Synchrotron Radiation, EarlyView.We present calculations on the number of illuminating photons per pixel required for elemental detection using X‐ray fluorescence, even with far‐from‐threshold excitation.Scanning fluorescence X‐ray microscopy is widely used for quantitative mapping of elemental concentrations, including in studies of essential but low‐concentration metals in cells ...

Propagation of Transionospheric Radio Beam Waves through a Turbulent Layer [PDF]
, 1988 108-113The problem of trans ionospheric radio waves propagating through a turbulent layer has been studied and analytical expressions for beam-wave wander and spread have been derived with the power-law spectrum of ionospheric irregularities by using ...

Journal of Synchrotron Radiation, EarlyView.A computed‐tomography method using full‐rotation rocking curves is developed to characterize 100 keV X‐ray beams from lapped Si(111) crystals, revealing systematic wavelength broadening while maintaining constant angular divergence in DuMond space.Lapping the surfaces of Si(111) crystals in a double‐crystal monochromator (DCM) has recently been shown ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, EarlyView.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures
British Journal of Management, EarlyView.Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.
