Psychological Implications of a Small Changes Approach to Weight Loss
While a small changes approach to weight management has shown promise in helping participants lose weight, the psychological impact of this approach has yet to be determined. The present study examines changes in depression, body satisfaction, and life satisfaction of participants in two separate …

Growth behavior of fibroblasts influenced by small changes in polymer structure
… acid in their original state or by introducing small changes in the surface structure of the polymers, by adopting different processing techniques (i.e. drawn and undrawn forms). Though, it is the most widely used scaffold, polylactic acid has been found to degrade faster and produce acidic end …

The Application of a Reporter Group to α-Chymotrypsin
… developed in order to obtain information about small changes in the environment at specific positions in protein molecules. In this method one environmentally sensitive group is introduced into a specific position in the protein so that small changes induced by substrates or modifiers can be …

Quantum Monte Carlo Calculations of the Electronic Excitations of Germanium Atoms, Molecules and Nanoclusters Using Core-Polarization Potentials
… total energy, and for excitations of atoms and small molecules. However, there are only small changes in the lowest optical excitations of larger clusters, which can be understood in terms of the nature of the excitations, mainly the relative Ge s to p atomic orbital character of the excited …

Relocation study of Virginia earthquakes (1959-1981) using the Joint Hypocenter Determination and Joint Epicenter Determination methods
… relocations produce, for the most part, only small changes in epicenters (<5 km average displacement) and comparably small changes in focal depths. Geometrically, they can be grouped into three planes and one cluster of events. The majority (17/25) of the events are contained in two of the …

Impedimetric Sensor System for Edible Oil Quality Assessment
… oil quality assessment are necessary. In fact, changes of the composition due to frying leads to variation of its dielectric parameters. This can be measured using a capacitive sensor and the measurement of its impedance change. The main challenge thereby is that the impedance changes are very …

A study to examine the validity and reliability of a selected group of physical fitness tests within a primary school setting
… (TE), coefficient of variation (CVTE) and smallest worthwhile change (SWC) were calculated for each sex and age group (grade). Changes in measurement were categorised as small, medium or large based on effect sizes. Results: The 20m shuttle run (SRT), hand grip strength (HGS), standing long …

Safety of Slow Release Lipopolysaccharide (LPS) Pellet in a Swine Model and Development of an Exogenous Reference Control for Real Time PCR
… exist in analytical methods used to measure small changes in gene expression of inflammatory mediators reflective of CI. Small changes may be disregarded as background noise due to the limitations of sensitivity and specificity inherent to a specific assay. As a result, current efforts are …

MDEA : malware detection with evolutionary adversarial learning
… approach has proved effective against dynamic changes, such as encrypting, obfuscating and packing techniques, it is vulnerable to specific evasion attacks to where that small changes to the input data cause misclassification at test time. In this paper, I propose MDEA, an Adversarial Malware …

Effects of Environmental Temperature on Sleep and Waking in Normal Rats and Rats With Basal Forebrain Damage
… 1981). Given the sensitivity of normal sleep to small changes in thermal stress, sleep disturbances produced by basal forebrain damage may, in part, be secondary to impaired thermoregulation.

Design, development, and testing of a stochastically modulated Raman spectrometer
… modulates the laser excitation wavelength. Small changes in excitation will proportionally shift the Raman scatter while having little effect on other spectral artifacts, including fluorescence.

Dielectric dispersion of poly(vinyl acetate) solutions
… solution and, thus, the magnitude of capacitance changes over a frequency range is considerably reduced. Because of the very small changes in capacitance, reproducible results are difficult to obtain and definite conclusions as to the relation of dispersion to molecular weight are impossible. …

Hydraulic Resistance due to Emergent Wetland Vegetation
… of hydraulic resistance was estimated in a small floodplain wetland near Stephens City, VA using the regression models developed from the flume data. MODFLOW was used to simulate a 4-hour flood event through the wetland. The vegetated open water surface was modeled as a highly conductive …

Structure-Property-Transfection Relationships in Polycation-mediated Non-viral DNA Delivery
… results. Results revealed that seemingly small changes in the structure of cationic polyelectrolytes can have profound consequences on their transfection activity.

Dynamic mechanical analysis of graphite/epoxy composites with varied interphases
… repeatable results and is capable of detecting small changes in composite constituents.

Timing-Aware Automatic Floorplanning of Partially Reconfigurable Designs for Accelerating FPGA Productivity
… optimization for faster implementation of layout changes, including addition of debug logic. Automatic generation of a timing-driven floorplan for a partially reconfigurable design aims to remove the need for implementation iterations to meet all constraints. Floorplan speculation may anticipate …

Enhancing persistence when optimally scheduling depot-level repair activity for the United States Marine Corps
… $450 million over a six-year horizon. Currently, small changes (for example, budget) to the input to this model produce non-intuitive revisions that are needlessly disruptive. The Marine Corps Materiel Command (MATCOM) recognizes this problem and has asked for enhancement of their current model to …

Predicting the Effects of Dimensional and Material Property Variations in Micro Compliant Mechanisms
… to obtain sensitivities of output parameters to small changes in known variables. This is done by including static equilibrium equations and pseudo-rigid-body model relationships with the kinematic vector loop equations. Examples are used to show a comparison of this method to other deterministic …
