The Role Of Stellar Feedback In Galaxy Evolution

, 2009
Aiming at understanding the role of stellar feedback in galaxy evolution, I present a study of the hot interstellar medium in several representative galaxies, based primarily on X-ray observations as well as theoretical modelling.

Preserving evidence integrity in full file system extractions: Assessing hash inconsistencies and potential solutions

Journal of Forensic Sciences, EarlyView.
Abstract Smartphone manufacturers' enhanced privacy and security measures, such as File‐Based Encryption (FBE), have disrupted traditional data extraction techniques, necessitating the adoption of Full File System Extraction (FFS). FFS requires booting a smartphone, decrypting its UserData partition, and accessing files individually, a process that ...

Corvus A: A Low-mass, Isolated Galaxy at 3.5 Mpc

The Astrophysical Journal Letters
We report the discovery of Corvus A, a low-mass, gas-rich galaxy at a distance of approximately 3.5 Mpc, identified in DR10 of the Dark Energy Camera Legacy Imaging Survey during the initial phase of our ongoing SEmi-Automated Machine LEarning Search for

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

Integrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

Integrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

On the Evolutionary History of a Simulated Disk Galaxy as Seen by Phylogenetic Trees

The Astrophysical Journal
Phylogenetic methods have long been used in biology and more recently have been extended to other fields—for example, linguistics and technology—to study evolutionary histories.

Objective-prism and slit-spectra redshifts in a study of the distribution of galaxies

, 2014
A thorough and detailed investigation into the accuracy, reliability and consistency of the objective-prism redshift technique with changes in plate material, measuring machine and reduction techniques has been undertaken.

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

Modelling and observations of molecules in discs around young stars [PDF]

, 2013
This thesis contains a study of molecules within circumstellar discs around young stars. Firstly, the chemistry of a disc around a young, Class 0 protostar is modelled.
