Decay of quantumness in a measurement process: Action of a coarse-graining channel

A model of a quantum measurement process is presented: a system consisting of a qubit in a superposition interacts with a measuring apparatus consisting of a N qubit state. Looking at the emerging, effective description of the apparatus given by the action of a coarse-graining channel, we have been able to recover information about the superposition coefficients of the system.We have also been able to visualize the death of quantum correlations between system and apparatus and the death of quantum coherences in the apparatus' effective state, in the limit of a strong coarse-graining action - a situation akin to decoherence, although it is not necessary to evoke any interaction with the surrounding environment.
Neuroscience and the Social Origins of Moral Behavior: How Neural Underpinnings of Social Categorization and Conformity Affect Everyday Moral and Immoral Behavior

Neuroscientific evidence identifies the brain networks and cognitive processes involved in people’s thoughts and feelings about their behavior. This helps individuals understand the judgments and decisions they make with regard to their own and others’ moral and immoral behavior. This article complements prior reviews by focusing on the social origins of everyday moral and immoral behavior and reviewing neuroscientific research findings related to social conformity, categorization, and identification to demonstrate (a) when people are motivated by social norms of others to follow particular moral guidelines, (b) what prevents people from considering the moral implications of their actions for others, and (c) how people process feedback they receive from others about the appropriateness of their behavior. Revealing the neural mechanisms involved in the social processes that influence the moral and immoral behaviors people display helps researchers understand why and when different types of interventions aiming to regulate moral behavior are likely to be successful or unsuccessful.
Verification of Group Key Management of IEEE 802.21 using ProVerif

Home Energy Management Systems (HEMS) contain devices of multiple manufacturers. Also, a large number of groups of devices must be managed according to several clustering situations. Hence, since it is necessary to establish a common secret group key among group members, the group key management scheme of IEEE 802.21 is used. However, no security verification result by formal methods is known. In this paper, we give the first formal verification result of secrecy and authenticity of the group key management scheme of IEEE 802.21 against insider and outsider attacks using ProVerif, which is an automatic verification tool for cryptographic protocols. As a result, we clarify that a spoofing attack by an insider and a reply attack by an outsider are found for the basic scheme, but these attacks can be prevented by using the scheme with the digital signature option.
Autism Spectrum Disorder Associated With Gut Microbiota at Immune, Metabolomic, and Neuroactive Level

There is increasing evidence suggesting a link between the autism spectrum disorder (ASD) and the gastrointestinal (GI) microbiome. Experimental and clinical studies have shown that patients diagnosed with ASD display alterations of the gut microbiota. These alterations do not only extend to the gut microbiota composition but also to the metabolites they produce, as a result of its connections with diet and the bidirectional interaction with the host. Thus, production of metabolites and neurotransmitters stimulate the immune system and influence the central nervous system (CNS) by stimulation of the vagal nerve, as an example of the gut-brain axis pathway. In this review we compose an overview of the interconnectivity of the different GI-related elements that have been associated with the development and severity of the ASD in patients and animal models. We review potential biomarkers to be used in future studies to unlock further connections and interventions in the treatment of ASD.
Evaluation of heterosis and heterosis retention in Bos taurus-Bos indicus crossbred cattle for productivity traits in cows

Reproductive and weight traits were analyzed for Angus (A), Brahman (B), Hereford (H), and Nellore (N) straightbred cows; F1 NA cows; 3/8N 5/8A cows and quarter blood composite cows (BANH) of the four straightbreds in Central Texas. Heterosis was estimated for calf crop born (CCB), calf crop weaned (CCW), and calf survival (CS) by linear contrasts within cow breed groups. F1 NA cows expressed heterosis (P < 0.0001) for CCB (0.22) and CCW (0.20). Except for the 3/8N 5/8Ac cows, which resulted from the mating of NA bulls to 3/4A 1/4N cows, all of the crossbred cow breed types expressed significant heterosis (P < 0.05) when compared to the weighted average of the parental purebreds for CCB. BANHc cows that were the result of mating NA bulls to HB cows expressed heterosis for CCB (0.35) (P < 0.001) and CCW (0.29) (P < 0.05). The 3/8N 5/8Aa females produced by mating 3/4N 1/4A bulls to NA cows expressed heterosis (P < 0.0001) for CCW (0.20). Heterosis for calf survival was near zero for all breed types, but only two breed types of 3/8N 5/8A cows were significantly greater than the weighted average of the parental purebreds. Heterosis for birth weight (BWT) and weaning weight (WWT) was also analyzed by linear contrasts within cow breed groups. The BANHb and BANHc cows produced from mating NA bulls to BH and HB F1 cows, respectively, expressed heterosis for BWT (2.89 + 0.79 (P < 0.001) and 3.38 + 1.51 (P < 0.05)). All cow breed types expressed significant heterosis (P < 0.05) for WWT. The BANH2 cows resulting from the mating of NA bulls to F2 HB or BH cows expressed heterosis (P < 0.0001) for WWT (52.01 kg + 9.88).
Development of programmable system on chip-based weld monitoring system for quality analysis of arc welding process

ABSTRACT Arc welding uses power sources of the constant current type having drooping characteristics or constant voltage characteristics. However, in reality, arc welding is a stochastic process due to random arc behaviour and metal transfer. The quality of a weld depends on the extent of these variations. The random signal amplitudes and time characteristics of the weldingsignal (voltage and current) allow a quality analysis of the welding process and disturbances. These random variations in current and voltage cannot be recorded with ordinary instruments. In the present work, a Programmable System on Chip based embedded Weld Monitoring System (WMS) with suitable software package was designed and developed to measure all the dynamic variations of welding voltage and current. Welding data were acquired using this WMS for the duration of 20 seconds at a sampling rate of 100,000 samples/s. The data obtained were filtered and subjected to the time domain and statistical analyses to evaluate various arc-welding parameters. The results obtained with WMS indicated that the same can be used for evaluating the welding consumables and assessing the skill of the welders. Thus, this work proposes a standalone, affordable, and an innovative tool for comprehensive on-line analysis of an arc-welding process.
Scholarship, Research, and Creative Work at Bryn Mawr College Scholarship, Research, and Creative Work at Bryn Mawr College

Recognizing Textual Entailment (RTE) was proposed as a uniﬁed evaluation framework to compare semantic understanding of different NLP systems. In this survey paper, we provide an overview of different approaches for evaluating and understanding the reasoning capabilities of NLP systems. We then focus our discussion on RTE by highlighting prominent RTE datasets as well as advances in RTE dataset that focus on speciﬁc linguistic phenomena that can be used to evaluate NLP systems on a ﬁne-grained level. We conclude by arguing that when evaluating NLP systems, the community should utilize newly introduced RTE datasets that focus on speciﬁc linguistic phenomena
First-Principles Study on the Magnetoelectric and Optical Properties of Novel Magnetic Semiconductor Li(Mg, Cr)P With Decoupled Spin and Charge Doping

The electronic structures, magnetic and optical properties of Li1±y(Mg1−xCrx) P (x, y = 0.125) are calculated by using the first principles method based on density functional theory. We find that the incorporation of Cr causes the strong hybridization between Li-2s, P-2p, and Cr-3d orbitals, resulting in a spin-polarized impurity band and forming stronger Cr-P polar covalent bonds. Li(Mg0.875Cr0.125)P becomes half-metallic ferromagnetism. The properties of the doped systems can be regulated by Li off-stoichiometry. When Li is deficient, the narrower impurity band and stronger p-d orbital hybridization enhance the half-metallicity. While the half-metallicity disappears, the band gap becomes wider, and the conductivity decreases for Li excess system, but its magnetic moments increase. Comparing optical properties show that the imaginary part of dielectric and complex refractive index function and optical absorption spectrum all have a new peak in the low energy region after Cr doping, and the new peaks are significantly enhanced when Li is deficient. The absorption range of low frequency electromagnetic wave is enlarged, and the energy loss functions show obvious red-shift effect for the doped systems. The results indicate that the properties of Li(Mg,Cr)P can be controlled by Cr doping and Li off-stoichiometry independently, which will benefit potential spintronics applications.
Security Testing of Second Order Permission Re-delegation Vulnerabilities in Android Apps

In Android, inter-app communication is a cornerstone feature where apps exchange special messages called Intents in order to integrate with each other and deliver a rich end-user experience. In particular, in case an app is granted special permission, it can dispatch privileged Intents to request sensitive tasks to system components.However, a malicious app might hijack a defective privileged app and exploit it as a proxy, to forward attacking Intents to system components. We call this threat “Second Order Permission Re-delegation” vulnerability.In this paper, we present (i) a detailed description of this novel vulnerability and (ii) our approach based on static analysis and automated test cases generation to detect (and document) instances of this vulnerability. We empirically evaluated our approach on a large set of top Google Play apps. Results suggest that this novel vulnerability is neglected by state of the art, but that it is common even among popular apps. In fact, our approach found 27 real vulnerabilities with fast analysis time, while a state-of-the-art static analysis tool could find none of them.
Using stable isotopes to determine seabird trophic relationships

1. The stable isotopes of nitrogen (δ 15 N) and carbon (δ 13 C) were analysed in 22 species of marine birds from coastal waters of the northeast Pacific Ocean. Analyses confirm that stable nitrogen isotopes can predict seabird trophic positions. 2. Based on δ 15 N analyses, seabird trophic-level inferences generally agree with those of conventional dietary studies, but suggest that lower trophic-level organisms are more important to several seabirds than was recognized previously. 3. Stable-carbon isotope analysis may be a good indicator of inshore vs. offshore feeding preference
Fluctuational transitions through a fractal basin boundary

Fluctuational transitions between two co-existing chaotic attractors, separated by a fractal basin boundary, are studied in a discrete dynamical system. It is shown that the mechanism for such transitions is determined by a hierarchy of homoclinic points. The most probable escape path from the chaotic attractor to the fractal boundary is found using both statistical analyses of ﬂuctuational trajectories and the Hamiltonian theory of ﬂuctuations.
Predicting the Outbreak Risks and Inflection Points of COVID‐19 Pandemic with Classic Ecological Theories

Predicting the outbreak risks and/or the inflection (turning or tipping) points of COVID‐19 can be rather challenging. Here, it is addressed by modeling and simulation approaches guided by classic ecological theories and by treating the COVID‐19 pandemic as a metapopulation dynamics problem. Three classic ecological theories are harnessed, including TPL (Taylor’s power‐law) and Ma’s population aggregation critical density (PACD) for spatiotemporal aggregation/stability scaling, approximating virus metapopulation dynamics with Hubbell’s neutral theory, and Ma’s diversity‐time relationship adapted for the infection−time relationship. Fisher‐Information for detecting critical transitions and tipping points are also attempted. It is discovered that: (i) TPL aggregation/stability scaling parameter (b > 2), being significantly higher than the b‐values of most macrobial and microbial species including SARS, may interpret the chaotic pandemic of COVID‐19. (ii) The infection aggregation critical threshold (M0) adapted from PACD varies with time (outbreak‐stage), space (region) and public‐health interventions. Exceeding M0, local contagions may become aggregated and connected regionally, leading to epidemic/pandemic. (iii) The ratio of fundamental dispersal to contagion numbers can gauge the relative importance between local contagions vs. regional migrations in spreading infections. (iv) The inflection (turning) points, pair of maximal infection number and corresponding time, are successfully predicted in more than 80% of Chinese provinces and 68 countries worldwide, with a precision >80% generally.
A Practical Guide to Resonance Frequency Assessment for Heart Rate Variability Biofeedback

Heart rate variability (HRV) represents fluctuations in the time intervals between successive heartbeats, which are termed interbeat intervals. HRV is an emergent property of complex cardiac-brain interactions and non-linear autonomic nervous system (ANS) processes. A healthy heart is not a metronome because it exhibits complex non-linear oscillations characterized by mathematical chaos. HRV biofeedback displays both heart rate and frequently, respiration, to individuals who can then adjust their physiology to improve affective, cognitive, and cardiovascular functioning. The central premise of the HRV biofeedback resonance frequency model is that the adult cardiorespiratory system has a fixed resonance frequency. Stimulation at rates near the resonance frequency produces large-amplitude blood pressure oscillations that can increase baroreflex sensitivity over time. The authors explain the rationale for the resonance frequency model and provide detailed instructions on how to monitor and assess the resonance frequency. They caution that patterns of physiological change must be compared across several breathing rates to evaluate candidate resonance frequencies. They describe how to fine-tune the resonance frequency following an initial assessment. Furthermore, the authors critically assess the minimum epochs required to measure key HRV indices, resonance frequency test-retest reliability, and whether rhythmic skeletal muscle tension can replace slow paced breathing in resonance frequency assessment.
Fostering Vicarious Resilience for Perinatal Palliative Care Professionals

Background: The demands on healthcare professionals caring for families grappling with a life-limiting condition in an unborn or newly born child can be overwhelming. Clinicians working in emergency/trauma, hospice, and pediatric settings are already at high risk for burnout and compassion fatigue, which can leave healthcare institutions increasingly vulnerable to poor retention, absenteeism, and waning quality of care. The provision of exemplary palliative care requires a cohesive interdisciplinary team of seasoned professionals resilient to daily challenges. In September 2019, the American College of Gynecology, in a committee opinion, published standard of care guidelines for perinatal palliative care. This has created an impetus for exceptional caregiving and a greater demand for both physician and interdisciplinary healthcare provider education, training, and ongoing support that promotes truly beneficent care for pregnant patients confronted with life-limiting fetal conditions. Methods: A scoping review of the research literature was conducted in order to distinguish the barriers and facilitators of professional resiliency in perinatal palliative care. PubMed, Medline, CINAHL, and EBSCO Psychology & Behavioral Sciences Collections were systematically reviewed. Because of the paucity of studies specific to perinatal palliative care, several interviews of nurses and physicians in that field were conducted and analyzed for content distinctly pertaining to personal practices or workplace factors that support or hinder professional resiliency. Results: The research indicated that medical professionals often cite a lack of knowledge, inexperience using effective communication skills related to perinatal palliative care and bereavement, challenges with interdisciplinary collaboration, misconceptions about the role and function of palliative care in the perinatal or neonatal settings, moral distress, and workload challenges as encumbrances to professional satisfaction. Strategic implementation of facility-wide bereavement care training, effective communication modalities, and evidenced-based practical applications are critical components for a thriving perinatal palliative care team. Authentic formal and informal debriefing, peer mentoring, adequate caseloads, robust provider self-care practices, exceptional relational efficacy, and cultural and spiritual humility can foster personal growth and even vicarious resilience for perinatal palliative care professionals. Conclusions: Support should be strategic and multifaceted. The onus to implement salient measures to cultivate resilience in the perinatal palliative caregiver should not be only upon the individuals themselves but also upon prevailing regulatory governing bodies and healthcare institutions.

Race-Conscious Career Development: Exploring Self-Preservation and Coping Strategies of Black Professionals in Corporate America

The Problem Corporations have maintained a history of operating as racialized social systems that contribute to racial divisions and inequities in the workplace. Despite this reality, there have been high-achieving Black men and women who have overcome limitations and unfavorable circumstances. In this study, resilience to racial bias in corporate America is explored through the lived experience of Black professionals by using a phenomenological research method. The Solution Race, racism, and workplace incivility are discussed in a conceptual framework to examine how racial bias still exists in the workplace and to contextualize the participants’ experiences. As a result of the findings, self-preservation and coping strategies are identified to provide insight into how the participants overcame social and racial barriers that influence their professional identities and career development in corporate America. The Stakeholders This research is intended to inform organizational leaders and career development researchers and specialists who are invested in the advancement of Black professionals and the communities they represent. This study also has implications for human resource developers and researchers who seek to minimize racial bias against Black professionals through racial discourse and race-conscious research.
DomainPKI: Domain Aware Certificate Management

Certificate Authority (CA) is a single point of failure in the trust model of X.509 Public Key Infrastructure (PKI), since CA is the only entity to sign and distribute public key certificates and no one else is involved in certificate verification. In response, recent fixes based on public logs have been successful in making certificate management more transparent and publicly verifiable. However, more recent researches have shown that none of existing solutions is fully satisfactory due to different security flaws and operational challenges. In this study, we propose a domain-aware alternative to mitigate those issues by involving domain owner in digital signature and certificate verification. Our proposal is based on current PKI design and business model with critical extensions of domain awareness. In order to engage domain owner in its certificate verification, we propose that each domain maintains its own certificate logs. A certificate is co-signed by a CA and its domain with a domain master key. To prove the authenticity of a certificate, a client first verifies the CA's digital signature, then the domain signature, and finally sends a query about the certificate status to its domain owner for further confirmation. By engaging domain owner in co-signing and verifying its certificates, we distribute the trust for certificate authenticity between the CA that signed this certificate and its domain owner. With these extensions, it will be extremely hard, if not impossible, for an adversary to make a successful attack to a client, and the damage of a successful attack is limited to this single client only. In this paper, we present a framework of our proposal, analyze its security gains and compare it with existing solutions.
