If you must pull off the road, use flashers, reflective triangles, and road flares to alert approaching drivers. Driving too fast for weather or road conditions or failing to slow down for curves or ramps create risks for spills and rollovers, as well as crashes. Make sure that pre-trip safety inspections are completed particularly for tires and brakes. Your life depends on them. Loose materials create road hazards.

After flattening the curve, Americans should expect a number of curveballs. Once the immediate crush of COVID cases subsides, epidemiologists say a “post-peak” purgatory lies ahead until a vaccine can be discovered and disseminated that would allow a return to normalcy. Given the uneven response at the state level — dozens of states have issued stay-at-home orders, starting with California on March 19; governors of eight states have not issued stay-at-home orders — the apexes of the coronavirus cases will hit different states at different times.
That makes any uniform national timetable impossible.

There is accumulating evidence suggesting that children may drive the spread of influenza epidemics. With alignment of the epidemic curves locally before aggregation of cases, slight age-specific differences in the timing of infection became apparent. For seasonal influenza, both the 10— and 20—year age groups peaked 1 week earlier than other age groups, while during the fall wave of the pandemic, infections peaked earlier among only the 10—year age group.
In the H3N2 seasons, infections occurred an average of 3. This analysis casts doubt on the hypothesis that younger school-age children actually lead influenza epidemic waves. Studies have shown that children have high clinical attack rates 1 , 2 , have high social contact rates within the school environment 3 — 5 , and play a major role in introducing influenza infections into the household 6 and in further transmission within the household 7.
A few studies identify older school-age students as the group most likely to drive the local spread 3 , 5. Most other studies include younger school-age children as the drivers of local spread, with some studies reporting community-wide benefits from the vaccination of school-age children 8. Viboud et al. The methods and data to assess the age differences in the timing of influenza infections are limited. Excess pneumonia and influenza admissions and other similar time series, such as emergency department visits for influenza-like illnesses, have been used to identify periods of influenza activity.
Using these data sources, Brownstein et al. Understanding the relative timing of influenza infections in different age groups is of importance to influenza burden studies that rely on proxy measures of influenza activity 12 —

History shows the dangers of relaxing restrictions too soon in a pandemic. And that, without a doubt, has saved lives. Serious cases, and deaths, could spike again, and waste all the progress that has been made so far. Flash Back Years. In some places it was worse than the first peak. Images emerging in recent weeks from New York City and Detroit, of body bags in hospitals lining hallways and stacked in refrigerated trucks, evoke a modern version of what Vaughan saw.

Most empirical work on the U. Phillips curve has had a strong tendency to impose global linearity on the data. The basic objective of this paper is to reconsider the issue of nonlinearity and to underscore its importance for policymaking. After briefly reviewing the history of the Phillips curve and the basis for convexity, we derive it explicitly using standard models of wage and price determination.
We provide some empirical estimates of Phillips curves and Phillips lines for the United States and use some illustrative simulations to contrast the policy implications of the two models. Password: Forgot your password? Login —OR— Create Account. Health Policy Public Health.

Handheld laser-induced breakdown spectroscopy HH LIBS was used to study the elemental composition of four copper alloys and four aluminum alloys to produce calibration curves. All three data sets of the spectra were averaged, and the intensity, corrected by subtraction of background, was used to produce the elemental calibration curves. Calibration curves are presented for the matrix elements, copper and aluminum, as well as several minor elements.
The surface damage produced by the laser was examined by microscopy. Works referenced in this record:. GOV collections:. Title: Calibration curves for commercial copper and aluminum alloys using handheld laser-induced breakdown spectroscopy.

This came in the same press conference when Governor Abbott confirmed that he would outline plans later this week to begin reopening some Texas businesses. The governor noted that the number of Texans who tested positive for COVID at the close of business Sunday was the lowest in a week and the second-lowest since late March. But he pointed out that Sundays often see the lowest numbers of the week in terms of people who test positive.
These predictions for Texas also estimate that on the day of its peak, the state will need 2, hospital beds, ICU beds, and ventilators. The updated numbers also predict that during the first wave of the virus through August , Texas will experience 2, COVID deaths.
This study used commercial data held by the Health Care Cost Institute but it is interesting to also study the age curve by service (inpatient, outpatient, pharmacy data, admission date for inpatient stays and service date for other providers.
At the outset of , the world looked on as China grappled with an outbreak that seemed be spiraling out of control. Two months later, the situation is markedly different. Now, numerous countries around the world are in the beginning stages of managing their own outbreaks. March 15th, , marked a significant statistical milestone for this, as confirmed cases of COVID outside of China surpassed the Chinese total.
As the number of new infections reported around the world continues to grow, which countries are winning the battle against COVID, and which are still struggling to slow the rate of infection? As of publishing time, 39 countries have passed the threshold of confirmed cases, with many more countries on the cusp. This was the case in the Lombardy region of Italy, where hospitals were overloaded and an increasing number of medical staff are under quarantine after testing positive for the virus.
Original concept by Drew Harris. While all the countries on this tracker are united behind a common goal — stamping out COVID as soon as possible — each country has its own approach and unique challenges when it comes to keeping their population safe. Of course, countries that are just beginning to experience exponential growth in case numbers have the benefit of learning from mistakes made elsewhere, and adopting ideas that are proving successful at slowing the rate of infection.
Drug launch curves in the modern era
It is wise to try and learn from the current situation in China, where the rate of COVID infections was extinguished as a result of a lockdown, and Italy, where hospitals are full and doctors have to make life-death decisions about patients because there are not enough beds to treat everyone in need. The mortality fraction of infected people appears to be higher by an order of magnitude when hospitals are overcrowded, so suppressing the rate of new infections serves the important purpose of allowing those in need to be treated.
If we do nothing, the current state of affairs is likely to worsen dramatically in the coming weeks. Our first plot shows the reported number of infections over time. For each country, Wikipedia has a continuously updated Web site with links to the original official sources such as the World Health Organization , research institutes and health ministries.

However, for most the term “Horseshoe Curve” describes a singular place, Pennsylvania Railroad’s PRR legendary crossing of the Allegheny Mountains within its home state. It was the company’s final effort in completing its original, Harrisburg-to-Pittsburgh main line. The project was spearheaded by PRR president John Edgar Thomson also the railroad’s first chief engineer in an exhaustive effort to maintain the lowest possible grades through the rugged Appalachian Mountains.
His ingenious design was so remarkable it eventually earned National Historic Landmark status and became not only a popular PRR location but also a nationwide attraction. Today, it still plays hosts to thousands of visitors and remains a vital artery of successor Norfolk Southern. The legislature authorized construction of its own canal, known as the Pennsylvania Canal, on February 25,
How close is Texas to ‘flattening the curve?’
Calibration curve is a regression model used to predict the unknown concentrations of analytes of interest based on the response of the instrument to the known standards. Some statistical analyses are required to choose the best model fitting to the experimental data and also evaluate the linearity and homoscedasticity of the calibration curve.
Using an internal standard corrects for the loss of analyte during sample preparation and analysis provided that it is selected appropriately. After the best regression model is selected, the analytical method needs to be validated using quality control QC samples prepared and stored in the same temperature as intended for the study samples.
Texas governor sees “glimmers of hope” in Texas data, models suggest that the state is still weeks away from the peak of its COVID curve.
How quickly will a drug in development reach peak revenues after launch? Anyone who builds financial models in the pharmaceutical industry has wrestled with this question — which is to say, every investor, analyst, banker, dealmaker, commercial team, franchise head and senior executive in the sector, not to mention scores of consultants and journalists focused on drug development and commercialization. The shape of the launch curve can dramatically affect financial models of pre-commercial drugs.
Because revenues are discounted to account for the ‘time value of money’, a fast ramp has an outsized effect on the projected net present value NPV. The most commonly used launch curve assumptions are based on an econometric model developed by Bauer and Fischer in Int. Bauer and Fischer’s work and a follow-up analysis using similar methodology and data Quant. First, the narrow therapeutic and pharmacological spectrum of agents studied — 36 agents in just four classes of cardiovascular drugs — is unrepresentative of the diversity of the industry today.
