The following article, Chicago Inmate Switches Identities While Wearing Mask…Is Released from Jail, was first published on 100PercentFedUp.com.

A Cook County, Chicago inmate, was able to switch identities with another inmate allowing the wrong inmate to be released. How did they carry that off without anyone catching them? The inmate was wearing a mask when he was released, so it wasn’t as easy to identify him. Last Saturday, Quintin Henderson (pictured below), 28, […]

The redox-based modifications of cysteine residues in proteins regulate their function in many biological processes. The gas molecule H₂S has been shown to persulfidate redox sensitive cysteine residues resulting in an H₂S-modified proteome known as the sulfhydrome. Tandem Mass Tags (TMT) multiplexing strategies for large-scale proteomic analyses have become increasingly prevalent in detecting cysteine modifications. Here we developed a TMT-based proteomics approach for selectively trapping and tagging cysteine persulfides in the cellular proteomes. We revealed the natural protein sulfhydrome of two human cell lines, and identified insulin as a novel substrate in pancreatic beta cells. Moreover, we showed that under oxidative stress conditions, increased H₂S can target enzymes involved in energy metabolism by switching specific cysteine modifications to persulfides. Specifically, we discovered a Redox Thiol Switch, from protein S-glutathioinylation to S-persulfidation (RTS^GS). We propose that the RTS^GS from S-glutathioinylation to S-persulfidation is a potential mechanism to fine tune cellular energy metabolism in response to different levels of oxidative stress.

The big story of the week is Wikileaks' CIA data dump, and we sandwich that topic between Apple's upcoming event and Nintendo Switch hardware issues. Lewis Painter kicks things off with Apple's (fingers crossed) late March event where we hope to see iPads, iMacs and get our six monthly fix of Jony Ive product videos. Then (13 minutes) Tamlin Magee tackles Vault 7 and the CIA's apparent ability to take control of iPhones and TVs, bypassing encryption. Will continuous leaks change anything? Finally (26 minutes) Dom Preston talks about his time over the last few weeks playing Zelda on the Nintendo Switch and why we should be a bit concerned about dodgy controllers.

As Emilio Pagan enters his first Spring Training with the Rays, he's looking to prove that he can perform well against hitters on either side of the plate.

Like so many pitchers in Major League camps, Orioles hurlers have extra sets of eyes on them this spring. The Edgertronic cameras, perched on tripods, are set about a stride's length beyond the backfield bullpen mounds at the club's Ed Smith Stadium complex, as conspicuous as the coaches standing cross-armed behind them.

Pitch clocks are set to make their Spring Training debuts this week, and it will be in games featuring hordes of players for whom playing on a timer is nothing new.

Most Major League teams still use a five-man starting rotation, but it takes a lot more pitchers than that to make it through a 162-game season. It certainly helps to have a potent one-two punch at the top of the rotation.

After seeing improved communication between pitchers and catchers last year, the "campfire" drill was put back on the D-backs' schedule and took place Friday at Salt River Fields.

Pakistan highlighted its talent on the pitch to draw the third and final Test against Sri Lanka in Sharjah and win the series 1-0, just days after three former team-mates were jailed for spot-fixing.

Australia's World Cup qualifier against Thailand next week has been moved to another stadium in Bangkok because of flooding in the city, Football Federation Australia said.

Two rural North Dakota school districts will switch to a four-day school week to save costs and improve student and teacher morale.

Wisconsin is one of a handful of states where how much schools will get this fall is still being debated in the state capitol.

State education departments' finance technology can cost millions to replace, but those systems are crucial for fiscal transparency and efficiency. Hawaii's is replacing its long-troubled system with a new one to go online this summer.

Given a response $Y$ and a vector $X = (X^1, dots, X^d)$ of $d$ predictors, we investigate the problem of inferring direct causes of $Y$ among the vector $X$. Models for $Y$ that use all of its causal covariates as predictors enjoy the property of being invariant across different environments or interventional settings. Given data from such environments, this property has been exploited for causal discovery. Here, we extend this inference principle to situations in which some (discrete-valued) direct causes of $ Y $ are unobserved. Such cases naturally give rise to switching regression models. We provide sufficient conditions for the existence, consistency and asymptotic normality of the MLE in linear switching regression models with Gaussian noise, and construct a test for the equality of such models. These results allow us to prove that the proposed causal discovery method obtains asymptotic false discovery control under mild conditions. We provide an algorithm, make available code, and test our method on simulated data. It is robust against model violations and outperforms state-of-the-art approaches. We further apply our method to a real data set, where we show that it does not only output causal predictors, but also a process-based clustering of data points, which could be of additional interest to practitioners.

Abstract:
Accurate short-term forecasts are indispensable for the integration of wind energy in power grids. On a wind farm, local wind conditions exhibit sizeable variations at a fine temporal resolution. Existing statistical models may capture the in-sample variations in wind behavior, but are often shortsighted to those occurring in the near future, that is, in the forecast horizon. The calibrated regime-switching method proposed in this paper introduces an action of regime dependent calibration on the predictand (here the wind speed variable), which helps correct the bias resulting from out-of-sample variations in wind behavior. This is achieved by modeling the calibration as a function of two elements: the wind regime at the time of the forecast (and the calibration is therefore regime dependent), and the runlength, which is the time elapsed since the last observed regime change. In addition to regime-switching dynamics, the proposed model also accounts for other features of wind fields: spatio-temporal dependencies, transport effect of wind and nonstationarity. Using one year of turbine-specific wind data, we show that the calibrated regime-switching method can offer a wide margin of improvement over existing forecasting methods in terms of both wind speed and power.

Abstract:
Fluorescing molecules (fluorophores) that stochastically switch between photon-emitting and dark states underpin some of the most celebrated advancements in super-resolution microscopy. While this stochastic behavior has been heavily exploited, full characterization of the underlying models can potentially drive forward further imaging methodologies. Under the assumption that fluorophores move between fluorescing and dark states as continuous time Markov processes, the goal is to use a sequence of images to select a model and estimate the transition rates. We use a hidden Markov model to relate the observed discrete time signal to the hidden continuous time process. With imaging involving several repeat exposures of the fluorophore, we show the observed signal depends on both the current and past states of the hidden process, producing emission probabilities that depend on the transition rate parameters to be estimated. To tackle this unusual coupling of the transition and emission probabilities, we conceive transmission (transition-emission) matrices that capture all dependencies of the model. We provide a scheme of computing these matrices and adapt the forward-backward algorithm to compute a likelihood which is readily optimized to provide rate estimates. When confronted with several model proposals, combining this procedure with the Bayesian Information Criterion provides accurate model selection.

In today's evolving business environment, every operational decision is critical -- and that includes best practices for managing the customer journey. The CRM platform is an integral part of the process. In fact, 91 percent of companies with more than 11 employees use a CRM system. Because of the time it saves and the structure CRM delivers, it can seem daunting for businesses to make a switch.

We can adapt flexibly to environment changes and search for the most appropriate rule to a context. The orbital prefrontal cortex (PFo) has been associated with decision making, rule generation and maintenance, and more generally has been considered important for behavioral flexibility. To better understand the neural mechanisms underlying the flexible behavior, we studied the ability to generate a switching signal in monkey PFo when a strategy is changed. In the strategy task, we used a visual cue to instruct two male rhesus monkeys either to repeat their most recent choice (i.e., stay strategy) or to change it (i.e., shift strategy). To identify the strategy switching-related signal, we compared nonswitch and switch trials, which cued the same or a different strategy from the previous trial, respectively. We found that the switching-related signal emerged during the cue presentation and it was combined with the strategy signal in a subpopulation of cells. Moreover, the error analysis showed that the activity of the switch-related cells reflected whether the monkeys erroneously switched or not the strategy, rather than what was required for that trial. The function of the switching signal could be to prompt the use of different strategies when older strategies are no longer appropriate, conferring the ability to adapt flexibly to environmental changes. In our task, the switching signal might contribute to the implementation of the strategy cued, overcoming potential interference effects from the strategy previously cued. Our results support the idea that ascribes to PFo an important role for behavioral flexibility.

SIGNIFICANCE STATEMENT We can flexibly adapt our behavior to a changing environment. One of the prefrontal areas traditionally associated with the ability to adapt to new contingencies is the orbital prefrontal cortex (PFo). We analyzed the switching related activity using a strategy task in which two rhesus monkeys were instructed by a visual cue either to repeat or change their most recent choice, respectively using a stay or a shift strategy. We found that PFo neurons were modulated by the strategy switching signal, pointing to the importance of PFo in behavioral flexibility by generating control over the switching of strategies.
