Abstract:
Emission control technologies installed on power plants are a key feature of many air pollution regulations in the US. While such regulations are predicated on the presumed relationships between emissions, ambient air pollution and human health, many of these relationships have never been empirically verified. The goal of this paper is to develop new statistical methods to quantify these relationships. We frame this problem as one of mediation analysis to evaluate the extent to which the effect of a particular control technology on ambient pollution is mediated through causal effects on power plant emissions. Since power plants emit various compounds that contribute to ambient pollution, we develop new methods for multiple intermediate variables that are measured contemporaneously, may interact with one another, and may exhibit joint mediating effects. Specifically, we propose new methods leveraging two related frameworks for causal inference in the presence of mediating variables: principal stratification and causal mediation analysis. We define principal effects based on multiple mediators, and also introduce a new decomposition of the total effect of an intervention on ambient pollution into the natural direct effect and natural indirect effects for all combinations of mediators. Both approaches are anchored to the same observed-data models, which we specify with Bayesian nonparametric techniques. We provide assumptions for estimating principal causal effects, then augment these with an additional assumption required for causal mediation analysis. The two analyses, interpreted in tandem, provide the first empirical investigation of the presumed causal pathways that motivate important air quality regulatory policies.

Californians are expected to reinstate bilingual education. The vote is likely to be a milestone in the rise of Latino voting power. Bad news for Donald Trump; worse news for the GOP.

Asthma disparities exist, with Latino children of Caribbean descent at risk for poor disease control. Controller medications reduce symptoms; however, medication adherence remains suboptimal. Identifying what factors predict poor medication adherence in at-risk groups could identify important treatment targets.

This study is the first to assess objective rates of medication use among children with asthma in Puerto Rico. Findings suggest that interventions incorporating family resources and addressing parental beliefs about medications may be of benefit across cultural groups. (Read the full article)

Childhood obesity is already prevalent by preschool age, particularly among Latinos. Parents have tremendous influence on factors that contribute to childhood obesity (eg, diet, physical activity); thus, family plays a crucial role in pediatric obesity prevention.

This randomized controlled trial examined the effect of a behavioral intervention involving Latino-American parent–preschool-aged child dyads. The intervention resulted in reductions in absolute BMI across the 3-month study period, with patterns suggesting the largest effect for obese children. (Read the full article)

Excess tissue oxygenation should be avoided during neonatal resuscitation, especially in premature infants. Delivered oxygen concentrations when using a self-inflating bag (SIB) at oxygen flows <1 L/min remain to be established.

Low oxygen concentrations (30%– 40%) can be delivered with a SIB at an oxygen flow <1 L/min. A practical scheme has been developed correlating the oxygen flow rate and the corresponding delivered fraction of oxygen when using a neonatal SIB. (Read the full article)

Latino children are diagnosed with autism spectrum disorders (ASDs) less often and later than white children. Primary care pediatricians (PCPs) may play an important role in early ASD identification for Latinos.

PCPs find it more difficult to assess for ASDs in Latinos with Spanish primary language, view Latino parents as less knowledgeable about ASDs, and experience frequent barriers to ASD diagnosis in Latino patients. Many PCPs do not offer recommended screenings in Spanish. (Read the full article)

Little is known about how pediatricians communicate with overweight Latino children and their parents regarding overweight and obesity.

Findings suggest that many overweight Latino children and their parents do not receive direct communication that the child is overweight, weight-management plans, culturally relevant dietary recommendations, or follow-up visits. (Read the full article)

For communities with significant numbers of Latino and immigrant residents, the barriers to an accurate 2020 Census count are high—and so are the stakes for their schools, which could lose hundreds of millions of dollars if counts are inaccurate.

Bajaj Platina 110 H-Gear, a 110cc motorcycle with an extra gear has been launched in the country recently and we were in Pune last week to ride it. The new Platina 110 H-Gear model is not just about a five-speed gearbox as there are multiple other updates that make the riding experience richer than before. […]

Other tools allow a sanity check of placement density vs available board space.  There is an older post "Skill code to evaluate all components area (Accumulative Place bound area)"  (9 years ago) that has a couple of examples that no longer work or expired.

This would be useful to provide feedback to schismatic and project managers regarding the component density on the PCB and how it will affect the routing abilities.  Thermal considerations can be evaluated as well 

Has anyone attempted this or still being done externally in spread sheets?

Hello, i am a student who is studying Allegro tool with SKILL.

I have a question about SKILL axlSegDelayAndZ0. The reference says this function "returns the delay and impedance of a cline segment."

I want to know how many components does this tool consider when calculating timing delay from the length. 

How steep is input signal's rise transition? Is rise transition shape isosceles trapezoid or differential increasing shape?

Also, if it is a multi fan-out, the rise transition time will be different net by net. How can this tool can calculate in this case?

I want to hear answers about these questions.

Thank you for reading this long boring questions, and i will be waiting for answers.

Hello,

I would like to simulate the PSSR+/PSSR- and the CMMR using xf for the attached test bench.

Normally, I do the AC analysis and using the post-processing capability of cadence spectre I do 20log(vdd/vout) for PSSR+

and 20*log(vss/vout) for PSSR-. 

looked online from an old post that I do:

PSRR-
db20(1/DATA("/Vn/PLUS" "xf-xf"))

PSRR+
db20(1/DATA("/Vp/MINUS" "xf-xf"))

How about the for the CMRR?

Thanks a lot in advance.  

I have a question regarding simulating IBIS model using Spectre.  IBIS model generation always has the die capacitance included and in the generated IBIS file you will have this value as  “C_comp” value.  Does the Spectre accounts for this capacitance from the IBIS file while computing the time domain voltage waveform during simulation ?  If I add additional capacitance outside in the testbench, to model the die capacitance, then it will be double counting.

Does anyone know if Spectre is already accounting this C_comp during the time domain voltage wave computation from IBIS file, during simulation ?

The renewable energy market is fast-paced and growing with each passing day. It’s hard to keep up with every industry announcement and insight, so we decided to highlight interesting developments that took place during the past few weeks, and some valuable insights that are worth revisiting.

Following the conclusion of the United Nations climate negotiations in Lima, Peru, last December, a busy schedule of breakout sessions has begun for Latin American business and political leaders in early 2015.

After being shut out of previous renewable energy auctions, and delaying its own auction by two weeks, the state government of Pernambuco held the nation's first solar energy auction on December 27, registering 122.82 MW of energy, six times the country's current entire solar energy output (20 MW). The auction involved 34 bidders proposing roughly 1 GW of capacity; at the end it was narrowed to six companies from Brazil, Italy, Germany, China and Spain. Average price of power finished trading at 228.63 Brazilian reais/MWh (just under U.S. $97), about 9 percent lower than the starting price of R 250.

The Rivers State Government has asked it's Attorney-General and Commissioner for Justice to auction all vehicles that were impounded for violating the state’s lockdown directive.

Paulinus Nsirim, the state's Commissioner for Information and Communications, in a statement on Thursday, said interested Nigerians should check selected Nigerian newspapers in order to place their bids.

The statement reads, “Government will deal decisively with the residents of these areas if they are found to default again. 

“Anyone parading exemption letters except the one issued by the governor is doing so at his or her own risk as such permits are invalid.

“The Attorney-General and Commissioner for Justice has been directed to auction all vehicles that violated the lockdown order.

“Members of the public who are interested to buy the auctioned vehicles are to watch out for details in The Sun, The Nation and Vanguard Newspapers.”
