This paper provides a review of recent investigations on the image processing techniques used to match spent bullets and cartridge cases. It is also, to a lesser extent, a review of the statistical methods that are used to judge the uniqueness of fired bullets and spent cartridge cases. We review 2D and 3D imaging techniques as well as many of the algorithms used to match these images. We also provide a discussion of the strengths and weaknesses of these methods for both image matching and statistical uniqueness. The goal of this paper is to be a reference for investigators and scientists working in this field. © 2012 Forensic Science Society. Source

Science and technology are not autonomous entities and research trajectories are largely influenced by public opinion. The role of political decisions becomes especially evident in light of rapidly developing new breeding techniques (NBTs) and other genome editing methods for crop improvement. Decisions on how those new techniques should be regulated may not be based entirely on scientific rationale, and even if it is decided that crops produced by NBTs do not fall under the umbrella of genetically modified organisms (GMOs), their commercialization is by no means certain at this time. If and when adopted regulations do not comply with the public's perception of risks, policy makers will find themselves under pressure to ban or restrict the use of the respective products. A plant breeding company has developed the first crop produced by a gene editing technology that does not contain foreign genetic material.The EU faces the challenge of how to handle next-generation plant breeding techniques.In January 2015, a coalition of eight NGOs published an 'open letter to the Commission on new genetic engineering methods' calling for stringent regulations on new breeding techniques.Most recent regulations on the cultivation of GM crops in the EU were shaped by public pressure. © 2016 Elsevier Ltd.

OBJECTIVE. The objective of our study was to evaluate whether the transition from film-screen mammography (FSM) to digital mammography (DM) was associated with increased detection of high-risk breast lesions. MATERIALS AND METHODS. A retrospective search identified 142 cases of atypia or lobular neoplasia (LN) diagnosed in women with mammographic calcifications between January 2004 and August 2010. We excluded lesions upgraded to cancer at excisional biopsy, lesions in women with ipsilateral cancer within 2 years of mammography, and lesions that presented as a mass only. The cases included in the cohort were 82 (57.7%) cases of atypical ductal hyperplasia; 17 (12%) atypical lobular hyperplasia; 25 (17.6%) lobular carcinoma in situ (LCIS); 12 (8.5%) atypia and LCIS; and six (4.2%) other atypia. The institution transitioned from predominantly performing FSM in 2004 to performing only DM by 2010. Pathology was interpreted by breast pathologists. The annual detection rate was calculated by dividing the number of high-risk lesions by mammography volume. RESULTS. Of the 142 cases of atypia or LN, 52 (36.6%) were detected using FSM and 90 (63.4%) were detected using DM. The detection rate was higher with DM (1.24/1000 mammographic studies) than FSM (0.37/1000 mammographic studies). The detection rate by year ranged between 0.21 and 0.64 per 1000 mammographic studies for FSM and between 0.32 and 1.49 per 1000 mammographic studies for DM. The median size of the calcifications was 8 mm on DM and 7 mm on FSM. The most common appearance was clustered amorphous or indistinct calcifications on both FSM and DM. CONCLUSION. The transition from FSM to DM was associated with a threefold increase in the detection rate of high-risk lesions. Improved detection may allow enhanced screening, risk reduction treatment, and possibly breast cancer prevention. However, increased detection of high-risk lesions may also result in oversurveillance and treatment. © American Roentgen Ray Society. Source

Current Opinion in Anaesthesiology | Year: 2014

Purpose of Review: The use of intraoperative magnetic resonance imaging (IMRI) during surgeries and procedures has expanded in the last decade. Not only is it becoming more commonly used for a variety of adult and pediatric neurosurgical procedures, but also its use has expanded to other types of surgeries. Along with using IMRI for removing tumors of the spinal cord, surgeons are now using it for other types of surgical operations of the kidney and liver. The increased utilization during the intraoperative period warrants the anesthesia provider to assure that patients and staff are unharmed because of increased risk of the powerful magnet. Recent Findings: Recent literature is reviewed regarding the expansive use of IMRI in the operating and procedure room. Safety issues and anesthetic implications are also addressed. Summary: IMRI is becoming increasingly more popular, especially with neurosurgeons, but its use is also expanding to other types of surgeries. Because of the increased use, the anesthesia provider must be aware of the dangers that it imposes to those involved and take necessary safety precautions. This will help assure that no one is harmed during the operation or procedure. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins. Source


Officers slammed me into a fountain soda machine because I was confused about which door they were asking me to walk out of — Wesley Lowery (@WesleyLowery) August 14, 2014 Detained, booked, given answers to no questions. Then just let out — Wesley Lowery (@WesleyLowery) August 14, 2014 Also Ryan Reilly of Huff Po. Assaulted and arrested — Wesley Lowery (@WesleyLowery) August 14, 2014 @ryanjreilly and @wesleyLowery have been arrested for "not packing their bags quick enough" at McD's #Ferguson — Ryan J. Reilly (@ryanjreilly) August 14, 2014 Unfortunately my last Vine featuring the officer who assaulted me was deleted when other my phone died. — Ryan J. Reilly (@ryanjreilly) August 14, 2014 One of the side stories over the Ferguson protests from last summer was the fact that the over-aggressive militarized police went in and arrested journalists who were covering the events in Ferguson. Two of the first journalists arrested were Ryan Reilly of Huffington Post and Wesley Lowery of the Washington Post. At the time, we highlighted how they had tweeted the lead up to their own arrests:A third reporter, Matt Pearce from the LA Times witnesses some of what happened and called the police chief -- and was told that it was all a mistake and that he had ordered the reporters released. After being released, Lowery and Reilly talked more about the ridiculousness of being arrested for, essentially, not getting out of the McDonalds fast enough:Given all that, you might think the local police would let the matter drop (though, if I were Lowery or Reilly I'm not sure I would have let them just drop it...). But, no, apparently the St. Louis County police are now debating whether to bring trespassing charges against the two reporters I'm trying to envision a scenario where this whole thing doesn't backfire in a ridiculous way for the St. Louis County police and prosecutors, and I'm struggling to find any possible way for them not to come out of this looking absolutely terrible. Both Lowery and Reilly are quick to point out how ridiculous the whole thing is:The article linked above notes that both reporters have continued their investigations into their own arrests, and have faced stonewalling at every turn, including police trying to deny their requests to find out the names of the officers who assaulted and arrested them. Moving forward with actual bogus "trespassing" charges would be not just adding insult to injury, but would, once again, call the world's gaze to St. Louis County and whatever the hell it is they call "justice" down there.
