Episode 2: Single Point Of Failure
A single point of failure (SPOF) is a part of a system that, if it fails, will stop the entire system from working. SPOFs are undesirable in any system with a goal of high availability or reliability, be it a business practice, software application, or other industrial system.
Episode 2: Single Point of Failure
The concept of a single point of failure has also been applied to fields outside of engineering, computers, and networking, such as corporate supply chain management and transportation management.

Honestly, I laughed out loud at last week's preview for "Single Point of Failure," which featured the threat of a "biohacker," but the show actually made some sound (and scary) points about how accessible a lot of this tech can be. The basic premise of tonight's hour is that a disgruntled hacker/bioengineer has constructed a custom virus that targets the children of people who had wronged him in the past. Which people? Why, former employees of a pharmaceutical company that yanked a promising drug trial for folks suffering from SMA (spinal muscular atrophy) to focus instead on the more lucrative asthma market. This modern threat certainly rings with authenticity as the words anthrax and Ebola have become commonplace in recent months and years. But Scorpion goes a step further by folding in some emotional context for our protagonists as well as for the episode's victims.
It is important to note that to calculate quality measures from OASIS data, there must be a complete quality episode, which requires both a Start of Care (initial assessment) or Resumption of Care OASIS assessment and a Transfer or Discharge OASIS assessment. Failure to submit sufficient OASIS assessments to allow calculation of quality measures, including transfer and discharge assessments, is a failure to comply with the CoPs. HHAs do not need to submit OASIS data for those patients who are excluded from the OASIS submission requirements. As described in the December 23, 2005, Medicare and Medicaid Programs: Reporting Outcome and Assessment Information Set Data as Part of the Conditions of Participation for Home Health Agencies final rule (70 FR 76202), we define the exclusion as those patients:
After the cessation of active variceal hemorrhage, the subsequent six weeks carry a high risk of recurrent hemorrhage. The greatest risk of rebleeding is within the first 48 to 72 hours, with more than 50 percent of episodes occurring within the first 10 days.18 Risk factors for early rebleeding include age older than 60 years, renal failure, large varices, and severe initial bleeding (i.e., hemoglobin less than 8 g per dL [80 g per L] at admission).18 A retrospective study showed that in-hospital mortality of patients with cirrhosis and variceal bleeding decreased from 43 percent in 1980 to 15 percent in 2000, in concurrence with an early and combined use of pharmacologic and endoscopic therapies and short-term antibiotic prophylaxis.19
Potential candidates for liver transplantation include any patient with documented fulminant hepatic failure, decompensated cirrhosis (including hepatorenal syndrome), or a hepatocellular carcinoma with no single lesion greater than 5 cm or no more than three lesions with the largest being 3 cm or smaller.30,31 Fulminant hepatic failure is a rare syndrome that arises from the loss of hepatic parenchymal function accompanied by encephalopathy and coma in patients who have had liver disease for less than eight weeks.
Fact: Atrial fibrillation is almost always a recurring disease and lifelong treatment is needed to minimize symptoms and to avoid stroke and heart failure. Early on, episodes of Afib tend to be sporadic and self terminating. These are called paroxysmal atrial fibrillation.
My hope is that if we can actually collect the large scale data sets that capture the ground source information about various kinds of failures as well as their successful counterparts, then can we actually put these datasets and data points under a scientific lens and to start to understand what are the signals underlying failures and success and what, is there any new relationships between them that we can uncover?
DASHUN WANG: So the major discovery of this study, a very surprising conclusion, namely a the discovery of tipping point between success and failure. You know, as people fail over and over these two groups of people can be actually quite similar in terms of their learning strategies or their characteristics.
On the other side of the tipping point, which is above this threshold, people fail over and over but they get fail faster and faster to eventually approach success. So this creates a quite a surprising prediction because what it means then is first of all, not all failures lead to success.
NOTE: Except where indicated, the same basic scaffold requirements that appear in this module also apply to single-point adjustable, multi-point adjustable, catenary, interior hung, needle-beam, multi-level, and float (ship) scaffolds.
Before kidney failure occurs, patients have "chronic kidney disease" (CKD). Kidney (renal) failure is when kidneys don't work as well as they should, to the point where kidney replacement is required. Kidney replacement can be accomplished by different kinds of dialysis or by kidney transplant. The term "kidney failure" covers a lot of problems. These problems can result in kidney failure:
On a mission to rescue the abducted son of Senator Dagonet, one of the Republic's longest serving members, Dooku and Jinn traveled to the Senator's home planet. To the stoic Jedi master and young Padawan's surprise, the planet's surface was little more than a wasteland which had been completely stripped of its natural resources and ravaged by over-industrialization. The two Jedi headed for a barren village in the distance. As they walked through the village, not a single resident dared step outside of their homes nor answer Qui-Gon's questions, which prompted them to enter the local inn. Fearless and keeping his unperplexed Jedi manner, Dooku immediately asked for the abducted child of the Senator twice. One of the villagers questioned why she should tell them, to which Dooku responded by producing his lightsaber. Once the villagers realized that Dooku and Qui-Gon were Jedi, Dooku stated their intention to resolve the situation and Qui-Gon assured the villagers that they were not acting on behalf of the Senator, which prompted the villager to ask how much they knew of the Senator. She explained that the village's desolate surroundings were proof that the Senator, who might have had good intentions at the beginning, had begun to neglect his people. Qui-Gon asked the villager why the people did not simply elect a new Senator, to which she replied that things were not so easy. She then agreed to show the Jedi where the Senator's son was located. At this point, Qui-Gon and Dooku were surprised to discover that virtually every visitor present at the inn had been involved in the kidnapping.
Dooku learned that King Katuunko was considering joining the Republic and was going to speak with his former master Yoda on the neutral moon, Rugosa. He sent his apprentice, Ventress, to convince him to join the Separatists. Ventress was able to make a deal with Katuunko and Yoda; If Yoda and his three troopers defeated her droid battalion, the Toydarians would be allowed to join the Republic, but if her droids captured Yoda, Katuunko would join the Separatists. Dooku approved of her deal, believing that Yoda made a mistake in venturing far from Coruscant. However, Yoda was able to defeat her droids, and Katuunko told Dooku that he would be joining the Republic upon seeing Ventress's treachery. Dooku urged him to reconsider, but to no avail, and ordered Ventress to kill the king. However, Yoda prevented the murder, and Dooku watched as Ventress made her escape, telling Yoda that his old master was fortunate he was not there in person. Dooku was disappointed in his assassin and developed a grudge against Katuunko in light of the mission's failure. 041b061a72
