Inequality Measures: The Kolkata Index In Comparison With Other Measures, Suchismita Banerjee, Bikas K. Chakrabarti, Manipushpak Mitra, Suresh Mutuswami

Journal Articles

We provide a survey of the Kolkata index of social inequality, focusing in particular on income inequality. Based on the observation that inequality functions (such as the Lorenz function), giving the measures of income or wealth against that of the population, to be generally nonlinear, we show that the fixed point (like Kolkata index k) of such a nonlinear function (or related, like the complementary Lorenz function) offer better measure of inequality than the average quantities (like Gini index). Indeed the Kolkata index can be viewed as a generalized Hirsch index for a normalized inequality function and gives the fraction …

Tracheostomy While On Extracorporeal Membrane Oxygenation: A Comparison Of Percutaneous And Open Procedures, Ismael A Salas De Armas, Kha Dinh, Bindu Akkanti, Pushan Jani, Reshma Hussain, Lisa Janowiak, Kayla Kutilek, Manish K Patel, Mehmet H Akay, Rahat Hussain, Jayeshkumar Patel, Chandni Patel, Yafen Liang, John Zaki, Biswajit Kar, Igor D Gregoric

Journal Articles

Although the ideal timing of tracheostomy for critically ill patients is controversial, transitioning from an endotracheal tube can be beneficial. Concerns arise for patients under extracorporeal membrane oxygenation (ECMO) support. Studies have described percutaneous and open tracheostomy approaches for critically ill patients but, to our knowledge, have not compared the two specifically in ECMO patients. This study analyzed safety and aimed to identify if there was a difference in major bleeding or other tracheostomy-associated complications. A single-center retrospective cohort study of all patients who received tracheostomy while on ECMO from July 2013 to May 2019 was completed. The primary endpoint …

Laboratory Versus Daily Life Gait Characteristics In Patients With Multiple Sclerosis, Parkinson’S Disease, And Matched Controls, Vrutangkumar V. Shah, James Mcnames, Martina Mancini, Patricia Carlson-Kuhta, Rebecca I. Spain, John G. Nutt, Mahmoud El-Gohary, Carolin Curtze, Fay B. Horak

Journal Articles

Background and purpose

Recent findings suggest that a gait assessment at a discrete moment in a clinic or laboratory setting may not reflect functional, everyday mobility. As a step towards better understanding gait during daily life in neurological populations, we compared gait measures that best discriminated people with multiple sclerosis (MS) and people with Parkinson’s Disease (PD) from their respective, age-matched, healthy control subjects (MS-Ctl, PD-Ctl) in laboratory tests versus a week of daily life monitoring.

Methods

We recruited 15 people with MS (age mean ± SD: 49 ± 10 years), 16 MS-Ctl (45 ± 11 years), 16 people with …

Enhanced Tensor Non-Gaussianities In Presence Of A Source, Abhishek Naskar, Supratik Pal

Journal Articles

We address the possibility of having an enhanced signal for tensor non-Gaussianities in presence of a source, as a signature of Primordial Gravitational Waves. We employ a nearly model-independent framework based on Effective Field Theory of inflation and compute tensor non-Gaussianities therefrom sourced by particle production during (p)reheating to arrive at an enhanced signal strength. We obtain the non-linearity parameters and also find that squeezed limit bispectra are more enhanced than equilateral limit.

Binary Black Hole Information Loss Paradox And Future Prospects, Ayan Mitra, Pritam Chattopadhyay, Goutam Paul, Vasileios Zarikas

Journal Articles

Various techniques to tackle the black hole information paradox have been proposed. A new way out to tackle the paradox is via the use of a pseudo-density operator. This approach has successfully dealt with the problem with a two-qubit entangle system for a single black hole. In this paper, we present the interaction with a binary black hole system by using an arrangement of the three-qubit system of Greenberger–Horne–Zeilinger (GHZ) state. We show that our results are in excellent agreement with the theoretical value. We have also studied the interaction between the two black holes by considering the correlation between …

Echoes Of 9/11: Rhetorical Analysis Of Presidential Statements In The "War On Terror", Bruce Ching

Journal Articles

This article examines persuasive statements by Presidents George W. Bush, Barack Obama, and Donald Trump involving appeals to national identity as a rhetorical foundation for anti-terrorism policy since 9/11. Their specific rhetorical methods have included the use of memorable catchphrases, alliteration, metaphorical framing, and contrast between values of the United States and those of the terrorists. President Bush focused on rallying the nation’s response against the perpetrators of the 9/11 attacks, identifying the U.S. with “freedom itself” and invoking the phrase “War on Terror.” President Obama emphasized the importance of the nation’s values while denouncing the Bush administration’s torture of …

Journal Articles

Variation in levels of the human metabolome reflect changes in homeostasis, providing a window into health and disease. The genetic impact on circulating metabolites in Hispanics, a population with high cardiometabolic disease burden, is largely unknown. We conducted genome-wide association analyses on 640 circulating metabolites in 3,926 Hispanic Community Health Study/Study of Latinos participants. The estimated heritability for 640 metabolites ranged between 0%-54% with a median at 2.5%. We discovered 46 variant-metabolite pairs (p value < 1.2 × 10

Prenatal Depression And Risk Of Short Interpregnancy Interval In A Predominantly Puerto Rican Population, Sami Backley, Alex Knee, Penelope Pekow, Glenn Markenson, Katharine O White, Corina Schoen, Lisa Chasan-Taber

Journal Articles

Background: Short interpregnancy interval (IPI) is associated with risk of adverse pregnancy outcomes; however, few studies have evaluated the role of depression as a risk factor for short IPI. Puerto Rican women in the United States experience disparities in adverse birth outcomes and have the highest birth rates.

Methods: We analyzed the association between prenatal depressive symptoms and IPI in Proyecto Buena Salud, a prospective cohort of predominantly Puerto Rican women in Western Massachusetts (2006–2011). Depression was measured using the Edinburgh Postnatal Depression Scale (EPDS) in early, mid, and late pregnancy. We calculated follow-up time as the difference between the …

Journal Articles

Background Excess visceral adipose tissue (VAT) is a primary driver for the cardiometabolic complications of obesity; VAT-associated cardiovascular disease risk varies by race, but most studies have been done on Non-Hispanics. This study aimed to evaluate the clinical and metabolic correlates of VAT, its association with subclinical atherosclerosis, and the factors affecting this association in Mexican Americans. Methods and Results Participants (n=527) were drawn from the Cameron County Hispanic Cohort (CCHC), on whom a carotid ultrasound to assess carotid intima media thickness and a dual-energy X-ray absorptiometry scan to assess for VAT were obtained. Those in the highest quartiles of …

Stochastic Resonance Reduces Sway And Gait Variability In Individuals With Unilateral Transtibial Amputation: A Pilot Study, Aaron Likens, Jenny A. Kent, C. Ian Sloan, Shane R. Wurdeman, Nicholas Stergiou

Journal Articles

Sub-threshold (imperceptible) vibration, applied to parts of the body, impacts how people move and perceive our world. Could this idea help someone who has lost part of their limb? Sub-threshold vibration was applied to the thigh of the affected limb of 20 people with unilateral transtibial amputation. Vibration conditions tested included two noise structures: pink and white. Center of pressure (COP) excursion (range and root-mean-square displacements) during quiet standing, and speed and spatial stride measures (mean and standard deviations of step length and width) during walking were assessed. Pink noise vibration decreased COP displacements in standing, and white noise vibration …

Gait Complexity Is Acutely Restored In Older Adults When Walking To A Fractal-Like Visual Stimulus, Joao R. Vaz, Brian Knarr, Nicholas Stergiou

Journal Articles

Typically, gait rehabilitation uses an invariant stimulus paradigm to improve gait related deficiencies. However, this approach may not be optimal as it does not incorporate gait complexity, or in more precise words, the variable fractal-like nature found in the gait fluctuations commonly observed in healthy populations. Aging which also affects gait complexity, resulting in a loss of adaptability to the surrounding environment, could benefit from gait rehabilitation that incorporates a variable fractal-like stimulus paradigm. Therefore, the present study aimed to investigate the effect of a variable fractal-like visual stimulus on the stride-to-stride fluctuations of older adults during overground walking. Additionally, …

Effect Of Bout Length On Gait Measures In People With And Without Parkinson’S Disease During Daily Life, Vrutangkumar V. Shah, James Mcnames, Graham Harker, Martina Mancini, Patricia Carlson-Kuhta, John G. Nutt, Mahmoud El-Gohary, Carolin Curtze, Fay B. Horak

Journal Articles

Although the use of wearable technology to characterize gait disorders in daily life is increasing, there is no consensus on which specific gait bout length should be used to characterize gait. Clinical trialists using daily life gait quality as study outcomes need to understand how gait bout length affects the sensitivity and specificity of measures to discriminate pathological gait as well as the reliability of gait measures across gait bout lengths. We investigated whether Parkinson’s disease (PD) affects how gait characteristics change as bout length changes, and how gait bout length affects the reliability and discriminative ability of gait measures …

Representation Of Ehr Data For Predictive Modeling: A Comparison Between Umls And Other Terminologies., Laila Rasmy, Firat Tiryaki, Yujia Zhou, Yang Xiang, Cui Tao, Hua Xu, Degui Zhi

Journal Articles

OBJECTIVE: Predictive disease modeling using electronic health record data is a growing field. Although clinical data in their raw form can be used directly for predictive modeling, it is a common practice to map data to standard terminologies to facilitate data aggregation and reuse. There is, however, a lack of systematic investigation of how different representations could affect the performance of predictive models, especially in the context of machine learning and deep learning.

MATERIALS AND METHODS: We projected the input diagnoses data in the Cerner HealthFacts database to Unified Medical Language System (UMLS) and 5 other terminologies, including CCS, CCSR, …

Reversing The Decriminalization Of Sexual Violence, Lisa Avalos

Journal Articles

Sexual violence has largely been decriminalized in the United States through disbelief of victims, apathy on the part of law enforcement officers, and inaction on the part of institutions. Indeed, these mechanisms are so effective at burying the problem that most people are not aware of the extent of unprosecuted sexual violence, the woefully deficient law enforcement response, and the need for sweeping reform. The Article proceeds in two parts. Part I maps the extent of this problem and argues that the weakest link in the societal response to sexual assault lies at the juncture between victim and law enforcement. …

Strength Of Plantar- And Dorsiflexors Mediates Step Regularity During A High Cognitive Load Situation In A Cross-Sectional Cohort Of Older And Younger Adults, Farahnaz Fallah Tafti, Kristen Watson, Julie Blaskewicz Boron, Sara A. Myers, Kendra K. Schmid, Jennifer M. Yentes

Journal Articles

Background and Purpose:

Completing simultaneous tasks while standing or walking (ie, a high cognitive load situation [HCLS]) is inevitable in daily activities and can lead to interference in task performances. Age-related physical and cognitive changes may confound performance variability during HCLS in older and younger adults. Identification of these confounding effects may reveal therapy targets to maintain optimal physical function later in life. The aim of this study was to investigate the effect of increasing the difficulty levels of an additional motor task and restricting visual information, on gait parameters in younger and older adults while considering the effect of …
