Abstract:

Introduction : La nouvelle attache préencollée APC™ Flash-Free du groupe 3M Unitek® permet-elle une simplification du protocole de collage sans en diminuer la précision ? Objectifs : L’objectif de cette étude est de comparer la morphologie du joint de colle entre les attaches préencollées classiques APC™PLUS et les attaches APC™ Flash-Free. Matériels et méthodes : Le collage in vitro des attaches esthétiques de la gamme CLARITY™ ADVANCED permet de comparer la morphologie des excès de colle entre les attaches APC™ PLUS et APC™ Flash-Free. Résultats : Aucune différence statistiquement significative concernant la morphologie des excès de colle n’est constatée entre les attaches APC™ PLUS et APC™ Flash-Free. Une différence statistiquement significative concernant l’épaisseur de colle existe entre les deux types d’attaches. L’épaisseur de colle au niveau des attaches APC™ Flash-Free est significativement plus importante que l’épaisseur au niveau des attaches APC™ PLUS (P=0,0001). L’épaisseur de colle est également plus homogène au niveau des attaches APC™ Flash-Free (P=0,001 pour la différence relative). Conclusion : L’épaisseur de colle au niveau des attaches APC™ Flash-Free est plus importante mais plus homogène qu’au niveau des attaches APC™ PLUS.

Abstract:

ABSTRACT Objectives: To compare bracket survival and adhesive removal time between a flash-free and a conventional adhesive for orthodontic bracket bonding. Materials and Methods: Forty-five consecutive patients had their maxillary incisors, canines, and premolars bonded with ceramic brackets using a flash-free adhesive (APC Flash-Free Adhesive, 3M Unitek, Monrovia, Calif) on one side and a conventional adhesive (APCII Adhesive, 3M Unitek) on the other side. The side allocation was randomized. Bracket failure was recorded at 4-week intervals. The adhesive remnant index (ARI) was scored on debond and adhesive removal timed to the nearest second. The primary outcome was adhesive removal time per quadrant. Secondary outcomes were bracket failure rate, time to first-time failure of a bracket, and ARI score on debond. Paired t-tests were used to compare adhesive removal times and ARI scores between the adhesives with P < .05 considered statistically significant. Results: Bracket failure rates were 4.3% for the flash-free adhesive and 1.9% for the conventional adhesive, with mean times to first-time failure of 31 weeks for the flash-free adhesive and 42 weeks for the conventional adhesive; neither failure rates nor times to first failure were significantly different. Although the flash-free adhesive left significantly more adhesive on the tooth surface after debonding, the adhesive removal times were 22.2% shorter than with the conventional adhesive. Conclusions: Bracket survival with the flash-free adhesive was equivalent to the conventional adhesive when ceramic brackets were bonded. Adhesive removal was significantly faster when using the flash-free adhesive, which may result in time savings of more than 20% compared with the conventional adhesive.

Abstract:

ABSTRACT Objective: To evaluate the bonding time, shear bond strength (SBS), and adhesive residue index (ARI) of APC(TM) Flash-Free bonding system. Materials and Methods: Thirty-six extracted human maxillary premolars were randomly divided into three groups (12 per group) and used for this in vitro study: group 1, APC Flash-Free Adhesive Coated Appliance System; group 2, Clarity ADVANCED Ceramic Bracket pasted manually; group 3 (control group), 3M APC PLUS Adhesive prepasted brackets bonded with the extruded flash removed. Bonding time was measured using a stopwatch. Bond strength was measured using an Instron at a cross-head speed of 1 mm/min. The ARI was graded on a scale from 1 to 5. Repeated-measures analysis of variance and post hoc Tukey tests were used for statistical analysis. Results: It took significantly (P < .001) less time to bond in the APC Flash-Free Adhesive group (30.7 ± 3.3 seconds) compared with the control group (41.8 ± 4.0 seconds) and the manual group (39.2 ± 2.8 seconds). The APC Flash-Free Adhesive coated bracket had significantly (P < .001) greater SBS (13.7 ± 2.2 MPa) compared with the control group (10.8 ± 2.0 MPa) and the manual group (10.4 ± 1.4 MPa). The ARI was significantly (P < .001) greater with the APC Flash-Free Adhesive coated bracket compared with that of the other two groups. Conclusions: Compared with other methods of bonding, the APC Flash-Free Adhesive Coated System can potentially reduce bonding time while increasing SBS.

Abstract:

Flash-Free Orthodontic Adhesive System represents the latest technology in the field of orthodontics. In the present study the bonding technique is applied on CAD/CAM produced resin crowns. Ten resin blocks were shaped after an upper premolar crown design from the 3Shape Library, and they were divided ino two groups: on Group 1, control, Clarity Advanced braces (3M Unitek, Monrovia, CA, USA) were bonded using XT Adhesive Paste (3M Unitek, Monrovia, CA, USA), while on Groups 2 same aesthetic brackets were applied, using the APC Flash-Free Adhesive Coated Appliance System (3M Unitek, Monrovia, CA, USA). Bracket positioning time was recorded for each sample. Zwick Zoel Z005 testing machine was used to measure the shear bond strength (SBS) at which debonding takes place. Adhesive remnant index (ARI) was registered, as well as presence or absence of adhesive flash and accuracy of flash cleaning before curing. Group 1 showed a mean bonding time of 46.4 s, while Group 2 needed about 20.6 s for each bracket bonding. Mean SBS values for both groups are considered clinically acceptable (6.27 MPa for Group 1 and 7.77 MPa for Group 2). ARI scores were zero for all samples and after debonding, on group 1 can be observed the adhesive flash. In conclusion, APC Flash-Free Coated Appliance System showed reduced time for bracket positioning compared to the conventional technique. APC Flash-Free System showed acceptable SBS values, higher than the uncoated brackets. No composite was left on the resin crown after debonding, the adhesive flash resulted in the conventional technique remaining on the edges of the debonded brackets.

Abstract:

The traditional flash translation layer (FTL) algorithm is mainly aimed at optimizing the average response time of flash reading and writing. Since it cannot be updated in place, for the traditional FTL algorithm, it is necessary to find a free page for writing each time. When a block is full, it will redistribute a free block. Therefore, when the flash memory is almost full, a written request will lead to a garbage collection, which will have many write copies, which will lead to a substantial decline in response time. This paper proposes an algorithm that makes full use of spatial locality and temporal locality to optimize the address cache in Demand-based Flash Translation Layer (DFTL) algorithm. In the experiment, this algorithm experiment and good results are obtained.

Abstract:

ABSTRACT Objectives To evaluate the effects of adhesive precoated (APC) flash-free brackets on the level of pain, amount of remnant adhesive, and removal time during the debonding procedure. Materials and Methods Thirty patients (20 female, 10 male) aged 12 to 18 years undergoing nonextraction fixed orthodontic treatment were included in this study. APC flash-free and conventional ceramic brackets were bonded with a split-mouth study design. Bracket types were randomly allocated to quadrants. During the removal of the brackets, the visual analogue scale (VAS) was used to assess the level of pain for each tooth. The adhesive remnant index (ARI) was used to determine the amount of adhesive remaining on the tooth surface. Adhesive removal times were calculated per quadrant. The data were analyzed using the Wilcoxon test for comparisons between groups. Results Pain scores were generally higher for the conventional group than for the flash-free group. There were no differences in VAS scores across most tooth types during debonding. Overall, ARI results showed more adhesive remnants in the conventional bracket group (P < .001). Except for the right maxillary quadrant, the times required to remove the adhesive were significantly longer for the flash-free brackets than the conventional brackets (P ≤ .005). Conclusions Although removal time was slightly longer for the flash-free adhesive than for the conventional adhesive, lower pain scores were generally observed for the flash-free adhesive brackets during the debonding procedure. Both time and pain differences could be considered clinically insignificant.

ABSTRACT Objective: To compare microleakage under 3M Unitek's APC Flash-Free Adhesive Coated System bracket and the APC PLUS Adhesive Coated System bracket after thermal cycling. Materials and Methods: Forty freshly extracted human maxillary premolars were randomly divided into two groups and bonded with either a Flash-Free bracket or a PLUS bracket. After bonding, the samples were incubated in a water bath at 37°C for 24 hours and thermocycled for 5000 cycles between 5°C and 50°C. All teeth were immersed in a 2% methylene blue solution for 24 hours, embedded in acrylic and sectioned in a buccolingual direction at approximately the center of the bracket. Microleakage was observed at the enamel-adhesive interface from the occlusal and gingival margins of the bracket base. Statistical analysis was conducted using the Mann-Whitney U-test. Results: The median microleakage was higher in the Flash-Free group, but the difference between the two groups was not statistically significant (P > .05). Conclusion: In a laboratory setting, there is no significant difference between the extent of microleakage under the APC Flash-Free Adhesive Coated System bracket and the APC PLUS Adhesive Coated System bracket after thermal cycling.

Abstract:

The commissioning of a terahertz-field-driven streak camera installed at the free-electron laser (FEL) FLASH at DESY in Hamburg, being able to deliver photon pulse duration as well as arrival time information with ∼10 fs resolution for each single XUV FEL pulse, is reported. Pulse durations between 300 fs and <15 fs have been measured for different FLASH FEL settings. A comparison between the XUV pulse arrival time and the FEL electron bunch arrival time measured at the FLASH linac section exhibits a correlation width of 20 fs r.m.s., thus demonstrating the excellent operation stability of FLASH. In addition, the terahertz-streaking setup was operated simultaneously to an alternative method to determine the FEL pulse duration based on spectral analysis. FLASH pulse duration derived from simple spectral analysis is in good agreement with that from terahertz-streaking measurement.

Abstract:

The considerable decrease in temperature and time makes FLASH sintering a more sustainable alternative for materials processing. FLASH also becomes relevant if volatile elements are part of the material to be processed, as in alkali-based piezoelectrics like the promising lead-free K0.5Na0.5NbO3 (KNN). Due to the volatile nature of K and Na, KNN is difficult to process by conventional sintering. Although some studies have been undertaken, much remains to be understood to properly engineer the FLASH sintering process of KNN. In this work, the effect of FLASH temperature, TF, is studied as a function of the particle size and impurity content of KNN powders. Differences are demonstrated: while the particle size and impurity degree markedly influence TF, they do not significantly affect the densification and grain growth processes. The conductivity of KNN FLASH-sintered ceramics and KNN single crystals (SCs) is compared to elucidate the role of particles’ surface conduction. When particles’ surfaces are not present, as in the case of SCs, the FLASH process requires higher temperatures and conductivity values. These results have implications in understanding FLASH sintering towards a more sustainable processing of lead-free piezoelectrics.

The ambient and denuded trench top corner at the step of gate oxidation play an important role to generate defect. Furthermore, dislocation-free flash process is proposed, and its mechanism as well. The impact on dislocation of the other processes is also discussed. And we knew that using of dry oxidation for gate oxide has the characteristic to reduce the dislocation. Consequently, the dislocation free wafer is obtained by changing gate oxide from wet to dry in manufacturing embedded flash.

Abstract:

Summary The conventional method for multiphase flash is the sequential usage of phase-stability and phase-split calculations. Multiphase flash requires the conventional method to obtain multiple false solutions in phase-split calculations and correct them in phase-stability analysis. Improvement of the robustness and efficiency of multiphase flash is important for compositional flow simulation with complex phase behavior. This paper presents a new algorithm that solves for stationary points of the tangent-plane-distance (TPD) function defined at an equilibrium-phase composition for isobaric-isothermal (PT) flash. A solution from the new algorithm consists of two groups of stationary points: tangent and nontangent stationary points of the TPD function. Hence, equilibrium phases, at which the Gibbs free energy is tangent to the TPD function, are found as a subset of the solution. Unlike the conventional method, the new algorithm does not require finding false solutions for robust multiphase flash. The advantage of the new algorithm in terms of robustness is more pronounced for more-complex phase behavior, for which multiple local minima of the Gibbs free energy are present. Case studies show that the new algorithm converges to a lower Gibbs free energy compared with the conventional method for the complex fluids tested. It is straightforward to implement the algorithm because of the simple formulation, which also allows for an arbitrary number of iterative compositions. It can be robustly initialized even when no K value correlation is available for the fluid of interest. Although the main focus of this paper is on robust solution of multiphase flash, the new algorithm can be used to initialize a second-order convergent method in the vicinity of a solution.

ABSTRACT Objectives To evaluate the effects of adhesive precoated (APC) flash-free brackets on enamel demineralization and periodontal status in patients during fixed orthodontic treatment. Materials and Methods Thirty patients, age 12 to 18 years, who had Angle Class I or Class II malocclusion with mild to moderate crowding in the permanent dentition were selected for this study. APC flash-free and conventional ceramic brackets were bonded for a split-mouth study design. The quadrant allocation was randomized. Demineralization records were obtained immediately after bonding (T0), 1 month after bonding (T1), and 6 months after bonding (T2). Clinical periodontal measurements, including gingival index, plaque index, and bleeding upon probing, were obtained before bonding (T0) and at the same time points (T1 and T2). Data were analyzed using Mann-Whitney U and Friedman tests to compare parameters between groups and times. Results Demineralization values decreased on most sides of the brackets for both groups between T0 and T1. In the conventional group, there was significantly higher demineralization on more sides compared with flash-free brackets between T1 and T2. With one exception, the decreased values were found in the incisal/occlusal sides of all brackets at T2. All periodontal parameters showed significant increases after 6 months of treatment in both groups. Intergroup comparison showed no significant differences in demineralization or periodontal measurements at any of the time points. Conclusions The effects of APC flash-free and conventional brackets on enamel demineralization and periodontal health did not differ from each other.

Abstract:

Flash floods are among the most common natural hazards in Egyptian and Arabian deserts. In this work, we utilized two Sentinel-1 and Sentinel-2 satellite images, before and after the flash flood, SRTM, and geolocated terrestrial photos captured by volunteers. This paper aims to three substantial objectives: (1) monitoring the flash flood impacts on Wadi El-Natrun region based on free satellite data and mapping the destroyed vegetation cover; (2) the integration of the free remote sensing data, geolocated terrestrial photos, and GIS techniques, along with hydrologic and hydraulic modeling, to evaluate the impact of flash flood hazards on the study area; and (3) assistance of the decision-makers in planning the required protective works to avoid the probable flooding. Two scenarios have been applied to estimate the flash flood effect. The first scenario has relied on Sentinel-1/2 data fusion before and after the flash flood, while the second scenario has been implemented based on the integration of the Sentinel-2 images and hydrologic and hydraulic flood modeling with the help of ArcGIS software to simulate the flash flood route. The results demonstrated that although the first scenario is an efficient solution for continuous monitoring of the change in the water bodies, it is limited in the detection of the submerged vegetation area. On the other hand, the second scenario provided the flash flood route and hydrological parameters, which determine the hazard degree of the basins, thus helping the decision-maker to manage the flood risk. Moreover, the second scenario surpasses the first one by estimating the destroyed infrastructure. Consequently, the second scenario is appropriate to assess the flash flood impacts and mitigate its influence in the future.

Abstract:

An extreme-ultraviolet (XUV) double-stage Raman spectrometer is permanently installed as an experimental end-station at the PG1 beamline of the soft X-ray/XUV free-electron laser in Hamburg, FLASH. The monochromator stages are designed according to the Czerny–Turner optical scheme, adapted for the XUV photon energy range, with optical elements installed at grazing-incidence angles. Such an optical scheme along with the usage of off-axis parabolic mirrors for light collimation and focusing allows for aberration-free spectral imaging on the optical axis. Combining the two monochromators in additive dispersion mode allows for reaching high resolution and superior stray light rejection, but puts high demands on the quality of the optical alignment. In order to align the instrument with the highest precision and to quantitatively characterize the instrument performance and thus the quality of the alignment, optical laser interferometry, Hartmann–Shack wavefront-sensing measurements as well as off-line soft X-ray measurements and extensive optical simulations were conducted. In this paper the concept of the alignment scheme and the procedure of the internal optical alignment are presented. Furthermore, results on the imaging quality and resolution of the first monochromator stage are shown.

Abstract:

Abstract. Most universities students depend on the use of proprietary software as it has prominent capabilities to meet their needs. Although the proprietary software such as Adobe Flash Professional has a high capability to create a web-based multimedia system, budget constraints become the main reason why free software will be used as an alternative to proprietary software. This study is carried out to evaluate the potential free software for developing a web-based multimedia in cartography projects specifically for students in developing countries. Wix and Weebly are the two software that has been potentially explored among the ten selected software in the market. The current commercial software (Adobe Flash Professional) was also applied as a benchmark to the selected free software. This three software were individually utilised to design and develop a web-based multimedia of e-sport system and their technical capabilities were comparatively assessed according to elements of a common multimedia, website and other mapping assessment aspects. The finding showed that each of the software has unique characteristics and has successfully generated the end products according to the standard web-based multimedia title. Although these free software could produce a better looking, more flexible and time saving mapping platform than the end product created from the Adobe Flash Professional, they have limitation in creating menu function. This exploratory and cases study has also demonstrated that the alternative free software has potentials to replace the current proprietary software, while Wix is the best among the two selected software.

Abstract:

Physical behavior can be assessed using a range of competing methods. The Free-Living Activity Study for Health (FLASH) is an ongoing study that facilitates the comparison of such methods. The purpose of this report is to describe the FLASH, with a particular emphasis on a subsample of participants who have consented to have their deidentified data released in a shared repository. Participants in the FLASH wear seven physical activity monitors for a 24-hr period and then complete a detailed recall using the Activities Completed Over Time in 24-hr online assessment tool. The participants can optionally agree to be video recorded for 30–60 min, which allows for direct observation as a criterion indicator of their behavior during that period. As of version 0.1.0, the repository includes data from 38 participants, and the sample size will grow as data are collected, processed, and released in future versions. The repository makes it possible to combine sensor data (e.g., from ActiGraph and SenseWear) with minute-by-minute contextual data (from the Activities Completed Over Time in 24-hr recall system), which enables the FLASH to generate benchmark data for a wide range of future research. The repository itself provides an example of how a powerful open-source tool (GitHub) can be used to share data and code in a way that encourages communication and collaboration among a variety of scientists (e.g., algorithm developers and end users). The FLASH data set will provide long-term benefits to researchers interested in advancing the science of physical behavior monitoring.

Abstract:

ABSTRACT Objective: To analyze the clinical and laboratory properties of the recently introduced APC flash-free orthodontic adhesive. Material and Methods: After bonding of 80 brackets on human teeth (group A: APC flash-free adhesive n = 40, group B: APC Plus adhesive n = 40), the following measurements were recorded: time for bonding, stereomicroscopic evaluation of excess adhesive, color penetration (methylene blue, 0.5%/24 h), and Adhesive Remnant Index (ARI) score after debonding. Results: The time needed for bonding differed significantly between the two groups (A: 19.5 s/tooth vs B: 33.8 s/tooth). The adhesive excess, which was metrically measured from the bracket edge, ranged from 166.27 µm to 81.66 µm (group A) and 988.53 µm to 690.81 µm (group B). After methylene coloration in group A, 52 of 80 measurements showed discoloration on the bracket-adhesive and/or adhesive-enamel interface, while for group B, 78 of 80 were coloration positive. The ARI scores did not differ, with an average ARI score of 2.0 for group A and 2.8 for group B. Conclusion: The flash-free adhesive significantly reduced the time needed for the bonding process. The excess resin expanded 0.16 to 0.08 mm over the bracket margin. The new technology seems to facilitate a smooth and sufficient marginal surface of the adhesive, which clinically might improve reduction of plaque accumulation.

Abstract:

Compared with the traditional hard-disk drives (HDDs), solid-state drives (SSDs) have adopted NAND flash memory and become the current popular storage devices. However, when the free space in NAND flash memory is not enough, the garbage collection will be triggered to recycle the free space. The activities of the garbage collection include a large amount of data written and time-consuming erase operations that can reduce the performance of NAND flash memory. Therefore, DRAM is usually added to NAND flash memory as cache to store frequently used data. The typical cache methods mainly utilize the data characteristics of temporal locality and spatial locality to keep the frequently used data in the cache as much as possible. In addition, we find that there are not only temporal/spatial locality, but also certain associations between the accessed data. Therefore, we suggest that a cache policy should not only consider the temporal/spatial locality but also consider the association relationship between the accessed data to improve the cache hit ratio. In the paper, we will propose a cache policy based on request association analysis for reliable NAND-based storage systems. According to the experimental results, the cache hit ratio of the proposed method can be increased significantly when compared with the typical cache methods.

Abstract:

The latest technology in the field of orthodontic materials is represented by the Flash-Free Orthodontic Adhesive System. In the present study this novel technique is compared with the conventional direct bonding method. Ten extracted human premolars were separated into two groups: in the Group 1, APC Flash-Free Adhesive Coated Appliance System (3M Unitek, Monrovia, CA, USA) was bonded, while in the control Group 2, Clarity Advanced braces (3M Unitek, Monrovia, CA, USA) were bonded using XT Adhesive Paste (3M Unitek, Monrovia, CA, USA) applied by the clinician on the bracket base. Bonding times were recorded for each sample. Shear bond strength (SBS) was recorded using Zwick Zoel Z005. After debonding, the adhesive remnant index (ARI) was established for both groups. Group 1 showed a mean bonding time of 21 s, while Group 2 needed about 45 s for each bracket bonding. Both groups had clinically accepted SBS values, but the difference between them was significant (10.97 MPa versus 8.23 MPa). ARI scores were equal to 1 for most samples. In conclusion, reducing the time for bracket placing, APC Flash-Free Coated Appliance System showed a brackets bonding time reduced to half compared to the conventional technique. This aspect, combined with significantly higher SBS values, makes this novel system better than the classical one. For both groups, more than half of the adhesive remained on the bracket base, which facilitates cleaning after debonding.

Abstract:

Flash memory is widely used in solid state drives (SSD), smartphones and so on because of their non-volatility, low power consumption, rapid access speed, and resistance to shocks. Due to the hardware features of flash memory that differ from hard disk drives (HDD), a software called FTL (Flash Translation Layer) was presented. The function of FTL is to make flash memory device appear as a block device to its host. However, due to the erase before write features of flash memory, flash blocks need to be constantly availed through the garbage collection (GC) of invalid pages, which incurs high-priced overhead. In the previous hybrid mapping schemes, there are three problems that cause GC overhead. First, operation of partial merge causes more page copies than operation of switch merge. However, many authors just concentrate on reducing operation of full merge. Second, the availability between a data block and a log block makes the space availability of the log block lower, and it also generates a very high-priced operation of full merge. Third, the space availability of the data block is low because the data block, which has many free pages, is merged. Therefore, we propose a new FTL named DSFTL (Dynamic Setting for FTL). In this FTL, we use many SW (sequential write) log blocks to increase operation of switch merge and to decrease operation of partial merge. In addition, DSFTL dynamically handles the data blocks and log blocks to reduce the operations of erase and the high-priced operation of full merge. Additionally, our scheme prevents the data block with many free pages from being merged to increase the space availability of the data block. Our extensive experimental results prove that our proposed approach (DSFTL) reduces the count of erase and increases the operation of switch merge. As a result, DSFTL decreases the garbage collection overhead.

Abstract:

The non-monochromatic beamline BL1 at the FLASH free-electron laser facility at DESY was upgraded with new transport and focusing optics, and a new permanent end-station, CAMP, was installed. This multi-purpose instrument is optimized for electron- and ion-spectroscopy, imaging and pump–probe experiments at free-electron lasers. It can be equipped with various electron- and ion-spectrometers, along with large-area single-photon-counting pnCCD X-ray detectors, thus enabling a wide range of experiments from atomic, molecular, and cluster physics to material and energy science, chemistry and biology. Here, an overview of the layout, the beam transport and focusing capabilities, and the experimental possibilities of this new end-station are presented, as well as results from its commissioning.

Abstract:

We evaluated the effects of extracts from the pomegranate (Punica granatum), vine (Vitis vinifera) seeds and garlic (Allium sativum) on free-radical reactions in human cells in relation to SNPs in the SOD2and СAT genes. The object was human peripheral leukocytes cultured in the presence of extracts from pomegranate (1.2; 2.4 %), garlic (0.5; 1.2 %) and vine seeds (1.2; 2.4 %). Intensity of free-radical reactions was assessed by a fast flash and flashlight sum of the luminol-dependent chemiluminescence (LDCL). Alleles of SOD2and СAT were analyzed using allele-specific PCR. The results showed that the pomegranate extract decreases LDCL intensity reliably in comparison with the control. Extracts of the garlic (1.2 %) and vine seeds (1.2 %) increase LDCL intensity. Correlation was established between the genotype determined by polymorphism of SOD2 gene Ala16Val (rs4880) and fast flash intensity during human cell cultivation with the extract of vine seeds (1.2 %).

Abstract:

Abstract Determination of the in vivo binding sites of RNA-binding proteins (RBPs) is paramount to understanding their function and how they affect different aspects of gene regulation. With hundreds of RNA-binding proteins identified in human cells, a flexible, high-resolution, high-throughput, highly multiplexible and radioactivity-free method to determine their binding sites has not been described to date. Here we report FLASH (Fast Ligation of RNA after some sort of Affinity Purification for High-throughput Sequencing), which uses a special adapter design and an optimized protocol to determine protein–RNA interactions in living cells. The entire FLASH protocol, starting from cells on plates to a sequencing library, takes 1.5 days. We demonstrate the flexibility, speed and versatility of FLASH by using it to determine RNA targets of both tagged and endogenously expressed proteins under diverse conditions in vivo.
