In the big closing session of the World Economic Forum in Davos, they recognised risks existed and badly run emerging markets might be vulnerable to shocks, but concluded that the outlook was brighter than it has been for many years.
Self-driving cars, selfie sticks, drones, touchscreen devices, e-cigarettes, jetpacks, and many other things seem like fairly modern inventions. Indeed, most of their "inventors" list them as newly invented and even go as far as seeking patents. But the fact is, many of these "inventions" have already been in existence for quite some time. They may have earlier lookalikes that ended up not going into production or that went into limited production due to one reason or another. Some also made it into full production but were recalled due to poor sales.
Still, the optimistic view is that several roadblocks to recovery -- an over-indebted consumer, a moribund housing market and shellshocked banks -- are no longer holding back hiring. Barring an unforeseen shock to the economy, this could mean 2013 will be another year of slow but steady growth.[qh]

In 2010, a 14-month-old child accidentally fell on a chopstick he had playfully placed into his nose. It did, indeed, puncture the roof of his nose and lodge into his brain. Neurosurgeons did successfully remove the chopstick, with little internal damage long term.

The nasal, or nasopharyngeal, swab for Covid-19 is a PCR (polymerase chain reaction) test looking for active infection, and remains the most accurate to date to assess for acutely infected individuals. This in contrast to the antigen, or rapid test, also performed as a nasopharyngeal swab, which is much less accurate, especially if the test result is negative (it has a very high false-negative rate). The antibody test, which is a blood test, is performed to detect evidence of prior infection, not active illness.

A 40-year-old woman in Iowa underwent a nasopharyngeal Covid-19 swab test as part of her preoperative clearance for an elective hernia repair. Soon after, she developed headache, nausea, vomiting, and clear watery drainage from the side of her nose where the swab had been placed. This was not the type of drainage one would get from allergies, a cold, or even a sinus infection. Picture your kitchen sink trickling out water if it’s not fully turned off. That’s what a spinal fluid leak can look like, which is what she had. In addition, the fact that a runny nose is just on one side is often a tip-off of something unusual. As published in the October issue of JAMA Otolaryngology, it turned out that she had had prior nasal polyp surgery two decades ago, as well as a history of disorder called intracranial hypertension, or increased pressure of the fluid surrounding the brain. The combination of these two entities led to a small defect in the bone between the roof of the nose and the brain, and she had developed a pocket of the brain’s lining prolapsing into the nose, known as an encephalocele. The sack of the encephalocele got nicked by the Covid-19 swab.

Radiologic imaging of her brain and sinuses demonstrated a one-inch area where there was no bony roof of her nose. Instead, there was an out-pouching of the brain’s lining, known as an encephalocele, filled with spinal fluid. The pouch got pierced by the swab, and just like piercing a water balloon that’s attached to a faucet, it immediately started leaking clear cerebrospinal fluid. Once this was identified, she underwent surgical repair of the defect in the bone, and the spinal fluid leak was controlled and repaired.

According to Dr. Jarrett Walsh, Assistant Professor of Otolaryngology-Head and Neck Surgery at the University of Iowa, and senior author of this report, “If the swab is introduced at an angle toward the skull base, then any defect in the skull base is potentially put at risk. Correct technique, following the floor of the nose, is exceptionally safe and will not cause skull base trauma.” When asked if he would recommend avoiding nasopharyngeal testing swabs in general, he thinks not: “Nasopharynx swabs, performed correctly, are safe...I think the group of patients that needs to exercise caution in testing are those who have had anterior (nasal) skull base surgery – specifically those who have had reconstruction of the anterior skull base. With missing bone between the nose and the brain, an errant swab could have significant consequences. This is the group that I would encourage considering an alternative testing technique, if it is available.”

When it comes to Covid-19 diagnostic testing, nasopharyngeal swab approach has been shown to be more accurate than oropharyngeal (oral) swab. However, in some cases, especially where a patient has had prior surgeries in the area between the nose and the brain, or prior injuries in that region, physicians will accept oropharyngeal testing for pre-procedure screening.

一次投入全部很少能够成功。虽然确实有人倾其所有,在六个月或一两年之后成为赢家,但这只是个案。对于任何初创公司来说,风险管理都是一个重要元素,账目平衡至关重要。如果你在最开始承担的风险更少,你就更容易消化损失。而这些损失将是必不可少的、富有价值的教训。
When he wasn't programming or doing schoolwork, D'Aloisio began to fill his spare time reading about natural language processing. He'd studied languages as diverse as Latin and Mandarin, and became fascinated by concepts like grammatical frameworks, morpheme parsing and the 1960s work of the linguist Richard Montague. 'He's my favorite,' D'Aloisio enthuses. 'He theorized that natural language could be described like a syntactical programming language.'
