Experimental evidnece for hysteresis in the cell cycles of Xenopus Laevis egg extracts
… of the regulation of M-phase promoting factor (MPF) activity in Xenopus laevis eggs and egg extracts. Although this model was in agreement with existing and subsequent experimental data, fundamental predictions that the cell cycle is driven by a hysteresis loop have never been validated …

A model of the checkpoint response of the cell cycle of frog-egg extracts in the presence of unreplicated DNA
… components), called M-phase Promoting Factor (MPF), and its key regulatory proteins Cdc25 and Wee1, are central parts of this cell cycle engine. Maintaining the fidelity of the DNA during the cell cycle is critical for successful propagation of the cell lineage. In the presence of unreplicated …

Bifurcation Analysis of a Model of the Frog Egg Cell Cycle
… in the activity of "M-phase promoting factor" (MPF), the crucial triggering enzyme for mitosis (nuclear division) and cell division. MPF activity is regulated by a complex network of biochemical reactions. Novak and Tyson, and their collaborators, have been studying the qualitative and …

Rent adjustment mechanism for the multifamily housing market
… tenant rent' actually paid by the tenants, and MPF (Market Product Fact), the 'asking rent' for the vacant unit. The results of this study clearly indicate that the rent adjustment models under study explain the MPF rent adjustment mechanism better than the CPI rent adjustment model. Chaning the …

Molecular Genetic Characterization of the Mating Pair Formation and Vegetative Replication Regions on the Agrobacterium Tumefaciens Ti Plasmid pTiC58
… of RP4, which encode mating pair formation (Mpf) functions essential for conjugation, as well as with other genes from the type IV secretion family. Expression of the Ti trb genes required the traI promoter, TraR, and AAI. Genetic studies showed that non-polar insertion mutations in 10 of the …

Role of materials & design on performance of baseball bats
… was a 30% reduction in the Multi-Piece Failures (MPF) of wooden bats once the requirement of a Slope of Grain (SOG) of 1:20 or 3 degrees was introduced in 2009. Further research into the implications of material and design can only help increase the safety to players and spectators.

The Effect of Posture During CPR on Rescuer Muscular Fatigue Development and CPR Quality
… kinetic data at the hands were collected. The MPF identified that four, six, four, and nine muscles fatigued during KH, LH, FH, and WH, respectively. Furthermore, there was a linear decrease in CC force and CC depth over time, during all positions. The results indicated that rescuers should …

Application of Dirichlet Distribution for Polytopic Model Estimation
… a DD marginalized particle filter (DDMPF) is also developed and implemented similar to MPF. The simulation results show that the newly proposed algorithms have better estimation accuracy, design simplicity, and computational requirements for PM estimation.</p>

Neuromotor Mechanisms Involved in the Recovery from Local Muscular Fatigue
… Surface EMG root-mean-square amplitude and MPF exhibited changes consistent with a warm-up effect. It was concluded that over-recovery was not present in the tibialis anterior following a local muscular fatigue. However, the return in force to initial values, rather than a persistent …

Neuromuscular responses to an isometric force and position task during passive hyperthermia
… (RMS) amplitude, mean power frequency (MPF) and median power frequency (MDF) for the force task. No change was observed in the sEMG signal for the positon task with passive heating, yet RMS amplitude increased upon skin cooling. Discrepancies in the sEMG signal exist between isometric …

The Monetary Theory and Practice of the Federal Reserve, 1914–35
… amend the System’s ‘monetary policy framework’ (MPF; policy framework)—or, in the words of Fed Chairman Jerome Powell, its ‘strategy for achieving its goals’.2 I immediately considered the specifics of the Fed’s earliest MPF. What were the System’s initial objectives? What strategies did it use …

Advanced Interference Suppression Techniques for Spread Spectrum Systems
… employs multiple-parallel feedback branches (MPF) for interference cancellation. The proposed scheme is further combined with multistage detectors to refine estimated symbols and provide uniform performance over all users. Simulation results show that the proposed space-time MPF-DF detector …

Friction and lubrication in metal rolling
This dissertation is concerned with the physical processes which determine friction and lubrication in metal rolling in the mixed lubrication regime, with particular attention paid to the conditions encountered when rolling aluminium foil. Two areas of relevance to the analysis of the rolling …

Innovative treatments for shelf-life extension of whole and fresh-cut fruit
… shorter shelf-life of minimally processed fruit (MPF) compared to intact product. This fact is strictly connected with the higher ethylene production of fruit tissue stimulated during fresh-cut processing (peeling, cutting, dipping). 1-Methylcyclopropene (1-MCP) is an inhibitor of ethylene action …

The Effect of Optic Flow During Attention Related Tasks and Quiet Stance
… mean square (RMS), and the mean power frequency (MPF) of Centre of Pressure (COP) and head position (HeadPos) were used to quantify balance. The mean angle RMS of relative angular displacement of the hip, knee and ankle was calculated, and the mean angle RMS of absolute angular displacement of the …

The role of frontal cortical-basal ganglia circuits in simple and sequential visuomotor learning
… (M1M2) motor cortices, medial prefrontal cortex (mPF) or sham surgery were tested on these tasks. Cortical lesions slowed RT in the VSRT task but did not impair short- or long-term simple S-R learning. Cortical lesions increased RTs for the initial response of a 5-response sequence in the SRT task …

The effect of acute low-load resistance exercise with the addition of blood flow occlusion on muscle function in children and adults
… differences, as BFO caused similar decreases in MPF for both groups. Thus, while adults use low-loads with BFO to simulate high-load training, it remains unclear whether this form of training would be as effective for children.
