A Genetic Analysis of the Adaptive Values of Populations [PDF]

open access: yesProceedings of the National Academy of Sciences, 1952
perpetuate themselves. Such efficiency of perpetuation may be termed adaptive value and its determination is of primary importance in the study of populations. Numerous methods, usually measures of selected physiological traits obviously relevant to the maintenance of the population, have been used for estimating adaptive values.

The Impact of Tenapanor on Body Composition and Blood Pressure in Peritoneal Dialysis Patients: A Pilot Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Instruction Tenapanor potentially affects fluid volume and blood pressure. This study explored its effects on these parameters in patients undergoing peritoneal dialysis (PD). Methods We conducted a single‐arm, prospective observational study that enrolled 10 patients on PD with hyperphosphatemia who were newly initiated on tenapanor.

Validity, Inter-rater Reliability, and Measures of Adaptive Behavior: Concerns Regarding the Probative versus Prejudicial Value [PDF]

open access: yes, 2018
: The question as to whether the assessment of adaptive behavior (AB) for evaluations of intellectual disability (ID) in the community meet the level of rigor necessary for admissibility in legal cases is addressed.

THE ESTIMATION OF ADAPTIVE VALUES OF EXPERIMENTAL POPULATIONS [PDF]

open access: yesEvolution, 1952
The concept of adaptive value is one of the fundamental concepts of population genetics. The adaptive value of the carriers of a given genotype is measured by their contribution to the gene pool of the next generation. ' Carriers of different genotypes within a population and also different populations of a species may be compared as to their adaptive ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Adaptive fuzzy filter algorithm for LEO communication channel estimation

open access: yesTongxin xuebao, 2006
A novel adaptive LMS filter algorithm based on fuzzy rules was proposed.Through building many fuzzy sets over the space of channel gained value and the increment value of channel gain,in addition to the setting of fuzzy rules,an adaptive algorithm ...

An Adaptive Cauchy Differential Evolution Algorithm for Global Numerical Optimization

open access: yesThe Scientific World Journal, 2013
Adaptation of control parameters, such as scaling factor (F), crossover rate (CR), and population size (NP), appropriately is one of the major problems of Differential Evolution (DE) literature.

Reward Modulates Unconsciously Triggered Adaptive Control Processes

open access: yesi-Perception, 2022
Adaptive control (e.g., conflict adaptation) refers to dynamic adjustments of cognitive control processes in goal-directed behavior, which can be influenced by incentive rewards.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
