Pooled CRISPR screens are a powerful tool to probe genotype-phenotype relationships at genome-wide scale. However, criteria for optimal design are missing, and it remains unclear how experimental parameters affect results. Here, we report that random decreases in gRNA abundance are more likely than increases due to bottle-neck effects during the cell proliferation phase. Failure to consider this asymmetry leads to loss of detection power.

Gear is one of the most common and important components in machinery. Evaluation on durability of gears plays crucial role in the assessment of the whole system reliability and service life. For other parts like shafts, the gears also act as loads. Therefore, dimensions and weight of the gears should be reduced as much as possible, contributing the size and weight reduction of the whole systems, which is essential to be cost-effectiveness.

Basic analyses were conducted upon an existing headlamp, and the validity of the analytical model was verified by testing existing reflector temperatures under conditions similar to those modeled during the analyses. Based on this verification, three types of radiating fins were modeled and analyzed. The vertical fin type exhibited the highest heat dissipation performance. Subsequently, design variables were selected for the vertical fin type and size optimization was performed using the design of the experiment model. Results confirmed a heat dissipation performance increase of 4.

This study aimed to optimize additional carrier concentration for spray drying of Pouzolzia zeylanica extract. Response Surface Methodology (RSM) with central composite design (CCD) was applied for optimization and investigation of the influence of maltodextrin (5ö15%, w/v) and carrageenan gum (0.06ö1.0%, w/v) concentration on the physicochemical characteristics of spray dried powder (bioactive compounds, moisture content as well as particle size distribution).

The advantage of using this model includes the optimal facilities, locating them and assigning the optimal facilities to them. It also chooses the type and the number of technologies, which must be bought. The fuzzy programming converts the multi objective model to an auxiliary crisp model by Jimenez approach and solves it with ߝ-constraint. For solving large size problems, the Multi Objective Differential Evolutionary algorithm (MODE) is applied.

Results show how different settings of kanban influence the performance of the assembly line feeding system. The biggest novelty item is certainly the recognition of the trade-off between kanban size and number of kanban and the importance of investigating its behaviour during the design of the system.

Successful pellet production has been reported in literature with cross-linked poly(vinylpyrrolidone), Polyplasdone® XL-10 and INF-10. In the present study, a quality by experimental design approach was used to assess several formulation and process parameter effects on the characteristics of Polyplasdone® XL-10 pellets, including pellet size, shape, yield, usable yield, friability, and number of fines. The hypothesis is that design of experiments and appropriate data analysis allow optimization of the Polyplasdone product.

The extraction conditions of polyphenols from Camellia dalatensis leaves were optimized by experimental design with five variables using Design-Expert V11.1.0.1 software. Using the methodology of response surface optimization, the optimal polyphenol extraction conditions were found to be an ethanol concentration of 49.29%, temperature at 60°C, a sonication time of 40min, a material size of 0.5mm, and a solvent/material ratio of 5.47.

A high demand for fungal lignin peroxidases on account of their innumerable biotechnological applications necessitates enhanced production This paper describes the enhanced production of lignin peroxidase by three isolates (LPS1, LPS2 and LPS3) of white rot fungi for delignification of crop residues. Initial screening of medium components was performed using a Plackett–Burman design and the variables with statistically significant effects such as pH, temperature, carbon source, nitrogen source, inoculums size, incubation period, inhibitors on lignin peroxidase production were identified.

This paper analyzes potential DVB-T2 transmission modes to optimize existing DTT network designs of Colombia, originally made for DVB-T, analyzing the trade-offs between capacity, coverage level and Single Frequency Network (SFN) size. Network planning results has been performed with a professional DTT network planning tool based on the three first deployment phases of the DTT network of the public national TV broadcaster RTVC. Results obtained fully justify the decision of adopting DVB-T2. Compared with the initial DVB-T design, DVB-T2 can increase the national covered population up to 7.

One of the most recent optimization techniques applied to the optimal design of photovoltaic system to supply an isolated load demand is the Artificial Bee Colony Algorithm (ABC). The proposed methodology is applied to optimize the cost of the PV system including photovoltaic, a battery bank, a battery charger controller, and inverter. Two objective functions are proposed: the first one is the PV module output power which is to be maximized and the second one is the life cycle cost (LCC) which is to be minimized.
