Key phrase extraction is one of the features offered by Azure Cognitive Service for Language, a collection of machine learning and AI algorithms in the cloud for developing intelligent applications that involve written language. Use key phrase extraction to quickly identify the main concepts in text. For example, in the text \"The food was delicious and the staff were wonderful.\", key phrase extraction will return the main topics: \"food\" and \"wonderful staff\".
To use key phrase extraction, you submit raw unstructured text for analysis and handle the API output in your application. Analysis is performed as-is, with no additional customization to the model used on your data. There are two ways to use key phrase extraction:
An AI system includes not only the technology, but also the people who will use it, the people who will be affected by it, and the environment in which it is deployed. Read the transparency note for key phrase extraction to learn about responsible AI use and deployment in your systems. You can also see the following articles for more information:
If a wisdom tooth doesn't have room to grow (impacted wisdom tooth), resulting in pain, infection or other dental problems, you'll likely need to have it pulled. Wisdom tooth extraction may be done by a dentist or an oral surgeon.
Most wisdom tooth extractions don't result in long-term complications. However, removal of impacted wisdom teeth occasionally requires a surgical approach that involves making an incision in the gum tissue and removing bone. Rarely, complications can include:
Your dentist may perform the procedure in the office. However, if your tooth is deeply impacted or if the extraction requires an in-depth surgical approach, your dentist may suggest you see an oral surgeon. In addition to making the area numb with local anesthetic, your surgeon may suggest sedation to allow you to be more comfortable during the procedure.

You and your doctor may determine that you need a tooth extraction for any number of reasons. Some teeth are extracted because they are severely decayed; others may have advanced periodontal disease, or have broken in a way that cannot be repaired. Other teeth may need removal because they are poorly positioned in the mouth (such as impacted teeth), or in preparation for orthodontic treatment.
After the blood clot forms it is important to not disturb or dislodge the clot. Do not rinse vigorously, suck on straws, smoke, drink alcohol or brush teeth next to the extraction site for 72 hours. These activities may dislodge or dissolve the clot and hinder the healing process. Limit vigorous exercise for the next 24 hours, as this increases blood pressure and may cause more bleeding from the extraction site.
We offer surgical services for those who need removal of teeth, replacement of teeth with dental implants, correction of their bites and facial cosmetic surgery. Top services: dental implants, TMJ (jaw joint) treatment, wisdom teeth removal, extractions, bone grafts and cleft lip and palate treatment.
Although permanent teeth were meant to last a lifetime, there are a number of reasons why tooth extraction may be needed. A very common reason involves a tooth that is too badly damaged, from trauma or decay, to be repaired. Other reasons include:
Infection. If tooth decay or damage extends to the pulp -- the center of the tooth containing nerves and blood vessels -- bacteria in the mouth can enter the pulp, leading to infection. Often this can be corrected with root canal therapy (RCT), but if the infection is so severe that antibiotics or RCT do not cure it, extraction may be needed to prevent the spread of infection.
Dentists and oral surgeons (dentists with special training to perform surgery) perform tooth extractions. Before pulling the tooth, your dentist will give you an injection of a local anesthetic to numb the area where the tooth will be removed. In some instances, your dentist may use a strong general anesthetic. This will prevent pain throughout your body and make you sleep through the procedure.
Once the tooth has been pulled, a blood clot usually forms in the socket. The dentist will pack a gauze pad into the socket and have you bite down on it to help stop the bleeding. Sometimes the dentist will place a few stitches -- usually self-dissolving -- to close the gum edges over the extraction site.
Although having a tooth pulled is usually very safe, the procedure can allow harmful bacteria into the bloodstream. Gum tissue is also at risk of infection. If you have a condition that puts you at high risk for developing a severe infection, you may need to take antibiotics before and after the extraction. Before having a tooth pulled, let your dentist know your complete medical history, the medications and supplements you take, and if you have one of the following (note that this list is not complete):
Nucleic acid isolation by organic extraction involves addition of phenol and guanidine isothiocyanate to separate the DNA, RNA, and proteins into different organic phases. Organic extraction is a low-cost method, and with advanced reagents such as TRIzol, is a straightforward process requiring very little equipment.
Magnetic bead isolation is now one of the most popular nucleic acid extraction methods due to its scalability and automation compatibility; MagMAX Bead Kits and KingFisher Sample Purification Systems are designed to work together to efficiently purify a variety of nucleic acids.
Our nucleic acid extraction instruments, kits and reagents are optimized to provide maximum yield, purity, and integrity from virtually any sample type. Whether you need to extract and purify RNA, viral nucleic acid, DNA fragments, plasmid DNA, or genomic DNA, Thermo Fisher Scientific has a solution.
Extraction solvents are solvents used in an extraction procedure during the processing of raw materials, of foodstuffs, or of components or ingredients of these products and which are removed but which may result in the unintentional, but technically unavoidable, presence of residues or derivatives in the foodstuff or food ingredient.
The EU Rules on extraction solvents for use in foodstuffs should take account primarily human health requirements but also, within the limits required for the protection of health, economic and technical needs.
Directive 2009/32/EC on the approximation of the laws of the EU countries on extraction solvents used in the production of foodstuffs and food ingredients applies to extraction solvents used or intended for use in the production of foodstuffs or food ingredients either in the EU or imported into the EU.
extraction solvents used in the production of food additives, vitamins and other nutritional additives, unless such food additives, vitamins or nutritional additives are listed in Annex I (of the Directive).
The EU countries shall not authorise the use of other substances and materials as extraction solvents, nor extend the conditions of use or permitted residues of the extraction solvents listed in Annex I beyond those specified therein.
It is essential that the technological need is well explained, including the reason for setting a maximum residual level at a certain level. It should also be clearly demonstrated that the (new) extraction solvent (use) would not be of safety concern.
The DNA molecule is structurally the same in all living things, including plants and animals. That being said, the product obtained from this extraction protocolmay look slightly different depending on whether it was extracted from a plant or an animal. For example, you may have more contaminants (proteins, carbohydrates)causing the DNA to appear less string-like, or the amount of DNA that precipitates may vary.
The extraction of DNA from a cell is often a first step for scientists who need to obtain and study a gene. The total cell DNA is used as a pattern to make copies(called clones) of a particular gene. These copies can then be separated away from the total cell DNA, and used to study the function of that individual gene.
This report documents the widespread adoption of MDFTs by law enforcement in the United States. Based on 110 public records requests to state and local law enforcement agencies across the country, our research documents more than 2,000 agencies that have purchased these tools, in all 50 states and the District of Columbia. We found that state and local law enforcement agencies have performed hundreds of thousands of cellphone extractions since 2015, often without a warrant. To our knowledge, this is the first time that such records have been widely disclosed.
We begin with a basic primer on how mobile device forensic tools (MDFTs) work and explain their capabilities with respect to data extraction, data analysis, and security circumvention. Our technical analysis surfaces three key points:
Many of the phones that law enforcement seize can be extracted with off-the-shelf tools. Departments often purchase tools from multiple vendors to increase the likelihood that any given phone can be extracted. Large MDFT vendors, like Cellebrite and Magnet Forensics, support extraction for thousands of phones. For example, in March 2016, Cellebrite supported logical extractions for 8,393 devices, and physical extractions for 4,254 devices. Since then, out of the five major phone manufacturers, Cellebrite added the most physical extraction support for Samsung (346 devices). Crucially, Cellebrite has also added lock-bypass support (e.g., by exploiting a vulnerability to force the phone to skip the passcode-checking step when it turns on) for about 1,500 devices since March 2016. However, as of 2017, 28% of smartphone users did not even have screen lock enabled on t
