Acceleration of FM-index Queries Through Prefix-free Parsing [PDF]

Algorithms Bioinform, 2023
FM-indexes are a crucial data structure in DNA alignment, for example, but searching with them usually takes at least one random access per character in the query pattern. Ferragina and Fischer observed in 2007 that word-based indexes often use fewer random accesses than character-based indexes, and thus support faster searches. Since DNA lacks natural

A SIMPLE ALPHABET-INDEPENDENT FM-INDEX [PDF]

International Journal of Foundations of Computer Science, 2006
We design a succinct full-text index based on the idea of Huffman-compressing the text and then applying the Burrows-Wheeler transform over it. The resulting structure can be searched as an FM-index, with the benefit of removing the sharp dependence on the alphabet size, σ, present in that structure.

FM latency, FM ratio, F-wave latency versus F-wave index in the diagnosis of diabetic neuropathy

The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2023
Background Diabetes is one of the most common causes for peripheral neuropathy which warrants early diagnosis and treatment. The conventional nerve conduction studies appear to be normal if few of the nerve roots are escaping the lesion.

Forensic perspective of foramen magnum— A CBCT study

Journal of Indian Academy of Oral Medicine and Radiology, 2023
Background: The purpose of the study is to evaluate the CBCT scans of both adult males and females and measure Foramen Magnum through transverse and sagittal diameter for calculating FM Index, which acts as a tool for sexual dimorphism in unidentifiable ...

Fibromyalgia in rheumatoid arthritis: features of pain syndrome, impact on disease activity and quality of life of patients

Современная ревматология, 2022
The prevalence of fibromyalgia (FM) in the general population is 2–8%, and among patients with rheumatic diseases it is 2–3 times higher. The presence of comorbid FM significantly affects the course of rheumatoid arthritis (RA).Objective: to assess the ...

Associations of Skeletal Muscle Mass and Fat Mass With Incident Cardiovascular Disease and All‐Cause Mortality: A Prospective Cohort Study of UK Biobank Participants

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background There is debate whether body mass index is a good predictor of health outcomes because different tissues, namely skeletal muscle mass (SMM) and fat mass (FM), may be differentially associated with risk.

A comprehensive evaluation of alignment algorithms in the context of RNA-seq. [PDF]

, 2012
Transcriptome sequencing (RNA-Seq) overcomes limitations of previously used RNA quantification methods and provides one experimental framework for both high-throughput characterization and quantification of transcripts at the nucleotide level.

Compressed Sparse FM-Index: Fast Sequence Alignment Using Large K-Steps [PDF]

IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2022
The FM-index is a data structure used in genomics for exact search of input sequences over large reference genomes. Algorithms based on the FM-index show an irregular memory access pattern, resulting in a memory bound problem. We analyze a recent implementation of the FM-index and highlight existing throughput-memory trade-offs, showing that memory ...
