Abstract:
In this paper, we study the persistent homology associated with topological crackle generated by distributions with an unbounded support. Persistent homology is a topological and algebraic structure that tracks the creation and destruction of topological cycles (generalizations of loops or holes) in different dimensions. Topological crackle is a term that refers to topological cycles generated by random points far away from the bulk of other points, when the support is unbounded. We establish weak convergence results for persistence diagrams – a point process representation for persistent homology, where each topological cycle is represented by its $({mathit{birth},mathit{death}})$ coordinates. In this work, we treat persistence diagrams as random closed sets, so that the resulting weak convergence is defined in terms of the Fell topology. Using this framework, we show that the limiting persistence diagrams can be divided into two parts. The first part is a deterministic limit containing a densely-growing number of persistence pairs with a shorter lifespan. The second part is a two-dimensional Poisson process, representing persistence pairs with a longer lifespan.

Abstract:
In this article, we study generalization of the classical Talagrand transport-entropy inequality in which the Wasserstein distance is replaced by the entropic transportation cost. This class of inequalities has been introduced in the recent work ( Probab. Theory Related Fields 174 (2019) 1–47), in connection with the study of Schrödinger bridges. We provide several equivalent characterizations in terms of reverse hypercontractivity for the heat semigroup, contractivity of the Hamilton–Jacobi–Bellman semigroup and dimension-free concentration of measure. Properties such as tensorization and relations to other functional inequalities are also investigated. In particular, we show that the inequalities studied in this article are implied by a Logarithmic Sobolev inequality and imply Talagrand inequality.

Abstract:
In the United States, county-level estimates of crop yield, production, and acreage published by the United States Department of Agriculture’s National Agricultural Statistics Service (USDA NASS) play an important role in determining the value of payments allotted to farmers and ranchers enrolled in several federal programs. Given the importance of these official county-level crop estimates, NASS continually strives to improve its crops county estimates program in terms of accuracy, reliability and coverage. In 2015, NASS engaged a panel of experts convened under the auspices of the National Academies of Sciences, Engineering, and Medicine Committee on National Statistics (CNSTAT) for guidance on implementing models that may synthesize multiple sources of information into a single estimate, provide defensible measures of uncertainty, and potentially increase the number of publishable county estimates. The final report titled Improving Crop Estimates by Integrating Multiple Data Sources was released in 2017. This paper discusses several needs and requirements for NASS county-level crop estimates that were illuminated during the activities of the CNSTAT panel. A motivating example of planted acreage estimation in Illinois illustrates several challenges that NASS faces as it considers adopting any explicit model for official crops county estimates.

On the frontline of climate change, effects are real and measurable. As climate change evolves, food and agriculture need to follow suit. Rising temperatures, changes in rainfall, erratic weather patterns and the prevalence of pests and diseases resulting from climate change threaten agricultural productivity and therefore undermine global food security. Simultaneously, the world’s population is growing steadily and expected to reach [...]

Some of the most innovative ways being used to improve agricultural practices involve nuclear technology.

Vatican City, May 6, 2020 / 05:30 am (CNA).- The coronavirus crisis can be an opportunity to recenter work on the dignity of each person, Pope Francis said in an appeal at the end of his general audience broadcast on Wednesday. 

“On May 1, I received several messages about the world of work and its problems. I was particularly struck by that of the agricultural workers, among them many migrants, who work in the Italian countryside. Unfortunately, many are very harshly exploited,” Pope Francis said May 6.

“It is true that the current crisis affects everyone, but people's dignity must always be respected. That is why I add my voice to the appeal of these workers and of all exploited workers. May the crisis give us the opportunity to make the dignity of the person and of work the center of our concern,” he said. 

Amid fears of a food shortage, the Italian government is currently discussing whether to legalize some undocumented migrant workers. These workers are particularly vulnerable to exploitation with illegal contracts that can pay less than half of Italy’s minimum wage for the agricultural sector.

May 1 is recognized as Labor Day in Italy and many countries throughout Europe, however it is not an official holiday in the Vatican, which instead celebrates the feast of St. Joseph the Worker, established by Pope Pius XII in 1955.

On the feast day, the pope asked St. Joseph to help Catholics fight for dignified work. He prayed that “no one might be without work and all might be paid a just wage.”

Pope Francis said in his Wednesday audience that prayer is “a cry that comes for the heart of those who believe and entrust themselves to God.” The pope began a new cycle of weekly catechesis on May 6 focused on prayer. 

“Not only do Christians pray, they share the cry of prayer with all men and women. But the horizon can still be widened. Paul says that the whole creation ‘groans and suffers the pains of childbirth,’” he said, quoting St. Paul’s letter to the Romans.

“The Catechism states that ‘humility is the foundation of prayer,’” the pope said. “Prayer … comes from our precarious state, from our continuous thirst for God.”

Pope Francis focused his catechesis on the Gospel account of Bartimaeus, the blind beggar from Jericho.

Bartimaeus “uses the only weapon in his possession: his voice. He starts shouting: ‘Son of David, Jesus, have mercy on me,’” the pope explained.

“And Jesus listens to his cry. Bartimaeus' prayer touches his heart, the heart of God, and the doors of salvation are opened for him,” he said. “He recognizes in that poor, helpless, despised man, all the power of his faith, which attracts the mercy and power of God.”

“Stronger than any argument, there is a voice in the human heart that calls out. We all have this voice inside. A voice that comes out spontaneously, without anyone commanding it, a voice that questions the meaning of our journey down here, especially when we are in the dark: ‘Jesus, have mercy on me! Jesus, have mercy on me!’ This is a beautiful prayer,” Pope Francis said.

Several studies have analyzed fatal or nonfatal youth injury incidence in US agricultural settings, but none have combined those estimates to form an overall picture. The only detailed study of costs related to such injuries is restricted to nonfatal injury.

This study provides a comprehensive analysis of the annual incidence and cost of agricultural youth injuries in the United States. It analyzes them from different perspectives: fatal versus nonfatal, at work versus not at work, and requiring hospitalization versus not requiring hospitalization. (Read the full article)

The Apgar score is a convenient method to rapidly assess the clinical status of the newborn infant. Recent literature suggests Apgar scores vary widely in preterm infants.

The Apgar signs for respiratory effort, grimace, and muscle tone demonstrated considerable disagreement in preterm infants ≤28 weeks’ gestation. Disagreement exists despite the level of respiratory intervention, continuous positive airway pressure, or intubation, and is likely independent of gestational age. (Read the full article)

Effective implementation of Pediatric Emergency Care Applied Research Network head trauma rules depends on their early application. As the registered nurse (RN) is often the first to evaluate children with blunt head trauma, initial RN assessments will be an important component of this strategy.

We demonstrated fair to moderate agreement between RN and physician providers in the application of the Pediatric Emergency Care Applied Research Network head trauma rules. Effective implementation strategies may require physician verification of RN predictor assessments before computed tomography decision-making. (Read the full article)
