Symmetries and physically realisable ensembles for open quantum systems

A D-dimensional Markovian open quantum system will undergo stochastic evolution which preserves pure states, if one monitors without loss of information the bath to which it is coupled. If a finite ensemble of pure states satisfies a particular set of constraint equations then it is possible to perform the monitoring in such a way that the (discontinuous) trajectory of the conditioned system state is, at all long times, restricted to those pure states. Finding these physically realisable ensembles (PREs) is typically very difficult, even numerically, when the system dimension is larger than 2. In this paper, we develop symmetry-based techniques that potentially greatly reduce the difficulty of finding a subset of all possible PREs. The two dynamical symmetries considered are an invariant subspace and a Wigner symmetry. An analysis of previously known PREs using the developed techniques provides us with new insights and lays the foundation for future studies of higher dimensional systems.
The Perception of Academic Plagiarism in Industrial Engineering Students at a Public University in Lima

The objective of this research was to study the perception of academic plagiarism as a dishonest behavior and the factors that characterize it in industrial engineering students at a public university in Lima. This work corresponds to a basic type of study with a quantitative approach, non-experimental design and cross-sectional descriptive level. From the operational field, the study variable was the perception of academic plagiarism, and its dimensions were knowledge, motivations and practices. The population consisted of 2145 students, and intentional non-probabilistic sampling was carried out, resulting in a sample of 155 students in the 8th and 9th cycles of this public university. For data collection, a questionnaire was designed with 35 questions referring to the variable and its dimensions, with each question having five response options according to a Likert-type scale which were answered virtually by the students. The results from the descriptive point of view reflect that 56.1% of the students perceived plagiarism in a negative way and 43.9% perceived it in an irrelevant way. In the inferential field, the results did not show significant statistical differences (p > 0.05). In conclusion, most students believe that academic plagiarism is a behavior that affects their education and is unethical and dishonest.
Genotyping of Coxiella burnetii from Cattle by Multispacer Sequence Typing and Multiple Locus Variable Number of Tandem Repeat Analysis in the Republic of Korea

Genotyping of Coxiella burnetii using multispacer sequence typing (MST) and multiple locus variable number tandem repeat analysis (MLVA) was conducted from infected animals for the first time in the Republic of Korea. C. burnetii was detected by real-time PCR, and followed by MST and MLVA genotyping. The result showed that detected C. burnetii all had the same MLVA genotype, 6-13-2-7-9-10 for markers MS23-MS24-MS27-MS28-MS33-MS34, respectively, and genotype group 61 for MST. The same genotypes were previously identified in Poland. Importantly, this MLVA type was detected in humans in France, suggesting that the Korean strain can also potentially cause Q fever in humans. MST and MLVA were very useful tools for analyzing the molecular epidemiology of C. burnetii and helpful for interpreting the epidemiological relationship between isolates from domestic and international resources.
Attention Detection by Heartbeat and Respiratory Features from Radio-Frequency Sensor

This work presents a study on users’ attention detection with reference to a relaxed inattentive state using an over-the-clothes radio-frequency (RF) sensor. This sensor couples strongly to the internal heart, lung, and diaphragm motion based on the RF near-field coherent sensing principle, without requiring a tension chest belt or skin-contact electrocardiogram. We use cardiac and respiratory features to distinguish attention-engaging vigilance tasks from a relaxed, inattentive baseline state. We demonstrate high-quality vitals from the RF sensor compared to the reference electrocardiogram and respiratory tension belts, as well as similar performance for attention detection, while improving user comfort. Furthermore, we observed a higher vigilance-attention detection accuracy using respiratory features rather than heartbeat features. A high influence of the user’s baseline emotional and arousal levels on the learning model was noted; thus, individual models with personalized prediction were designed for the 20 participants, leading to an average accuracy of 83.2% over unseen test data with a high sensitivity and specificity of 85.0% and 79.8%, respectively
Myofascial Trigger Points and Central Sensitization Signs, but No Anxiety, Are Shown in Women with Dysmenorrhea: A Case-Control Study

Simple Summary In this study, a biologic tissue characteristic present in chronic pain conditions—myofascial trigger points—was assessed in a sample of women with primary dysmenorrhea (PD) and compared with a group of healthy subjects. The presence of alterations in cerebral pain management—central sensitization—and pain related anxiety, were also addressed. Women with PD showed symptoms of myofascial pain syndrome and central sensitization, but no pain-related anxiety. The results of the present study could guide physical therapy practitioners into more accurate techniques focused on identification and treatment of myofascial trigger points, taking into consideration the possible presence of central sensitization processes in these patients, which need to be identified and, if present, considered a therapeutic target. Abstract Background primary dysmenorrhea (PD) is considered to be a cyclic chronic pelvic pain, with its onset in menstrual periods, often accompanied by the presence of myofascial trigger points (MTP). Most MTPs in subjects with chronic pelvic pain are in the inferior part of the abdomen, in the rectus abdominis (RA) area. Central sensitization is closely related to chronic pain processes. Previous studies in women with chronic pelvic pain reported central sensitization signs in their subjects, such as lower pain pressure threshold (PPT). Several authors agree that PPT in the tibialis anterior (TA) muscle, seems to be a reliable reference for signs of central sensitization. Amongst the factors that seem to accompany central sensitization, the presence of anxiety needs to be considered. The aim of the present study was to analyze the existence of hyperalgesic MTPs in RA, central sensitization signs and anxiety in women with PD, in comparison with a control group (CG). Methods: This study was designed following an observational, cross-sectional, case-control model. A total sample of 80 subjects was recruited trough social webs and advertising (PD n = 39) (CG n = 41). PPT in RA and AT was assessed bilaterally through algometry, and anxiety was evaluated through the State–Trait Anxiety Inventory. Results: Statistically significant differences (p < 0.001) were shown for NRS average and maximum increase, as well as lower bilaterally RA and TA PPT in favor of PD group compared to CG. State or trait STAI did not show any statistically significant differences (p > 0.05) between groups. Conclusions: In this study, women with PD reported symptoms of myofascial pain syndrome and central sensitization, when compared with healthy controls, without any sign of anxiety acting as a confounder for pain sensitivity.
Quality of Life and Stress Management in Healthcare Professionals of a Dental Care Setting at a Teaching Hospital in Rome: Results of a Randomized Controlled Clinical Trial

In the healthcare environment, more and more people experience work-related stress. The Faculty of Medicine and Dentistry of Sapienza University of Rome, having observed the need to take care of healthcare professionals, has set itself the objective of providing useful tools such as additional and necessary personal protective equipment for healthcare professionals. Objective: To promote health through better management, skills, and the use of strategies and solutions to identify, decompress, and neutralize those responsible for work-related stress mechanisms in order to take care of those who care (CURARE CURANTES). Materials and Methods: A randomized controlled clinical trial was conducted. The participants were enrolled by three departments of the Department of Dental and Maxillofacial Sciences of Rome; in consideration of emotional involvement of health professionals who work there. A motivational program was offered. Results: There were 17 and 16 healthcare professionals in the intervention and control groups, respectively. Levels of the mental composite score (MCS) varied both in the pre–post phase of the intervention group (p = 0.002), and between the intervention group and control group in the post phase (p = 0.006). No significant differences were observed for the physical composite score (PCS). Similarly, there were no significant differences regarding the positivity scale (PS) and the two dimensions of work-related stress (job demand and decision latitude). Conclusion: This study demonstrates the efficacy of yoga training practiced directly in the workplace and wearing work clothes, entering the work context, not weighing further on the healthcare workload, and being a way to carry out physical activity even in those cases in which professionals do not have the time to do it in their free time.
Isometric immersions into ⁿ×ℝ and ℍⁿ×ℝ and applications to minimal surfaces

We give a necessary and sufficient condition for an n-dimensional Riemannian manifold to be isometrically immersed in S n x ℝ or ℍ n × ℝ in terms of its first and second fundamental forms and of the projection of the vertical vector field on its tangent plane. We deduce the existence of a one-parameter family of isometric minimal deformations of a given minimal surface in S 2 × ℝ or ℍ 2 x R, obtained by rotating the shape operator.
Exact coherent states with hairpin-like vortex structure in channel flow

Hairpin vortices are widely studied as an important structural aspect of wall turbulence. The present work describes, for the first time, nonlinear travelling wave solutions to the Navier–Stokes equations in the channel flow geometry – exact coherent states (ECS) – that display hairpin-like vortex structure. This solution family comes into existence at a saddle-node bifurcation at Reynolds number $Re=666$ . At the bifurcation, the solution has a highly symmetric quasi-streamwise vortex structure similar to that reported for previously studied ECS. With increasing distance from the bifurcation, however, both the upper and lower branch solutions develop a vortical structure characteristic of hairpins: a spanwise-oriented ‘head’ near the channel centreplane where the mean shear vanishes connected to counter-rotating quasi-streamwise ‘legs’ that extend toward the channel wall. At $Re=1800$ , the upper branch solution has mean and Reynolds shear-stress profiles that closely resemble those of turbulent mean profiles in the same domain.
Self-regulation and social influence: a limited-resource account of resisting and yielding to persuasion

The research presented in this dissertation focuses on the internal process that takes place when people are being confronted with situations of social influence. A situation which is characterized by an influence agent - most likely a compliance professional like a sales representative, marketer, or fundraiser - persuading a target of influence into complying with a request, such as purchasing a product, subscribing to a service, or donating money to a charity organization. Although a predominant part of these requests is unsolicited, and initially received with a sceptical response, influence agents are often stunningly successful in eliciting compliance, and manage to urge their targets to respond in their desired way. An intriguing question to ask, therefore, is what makes people comply with these types of persuasive requests without any overt pressure. What makes it so hard to say “No” when confronted with an (unwanted) influence attempt? And given that knowledge, what determines whether people succeed at resisting persuasion? The research presented in this dissertation approaches these questions from a self-regulation perspective. In a series of experimental (lab and field) studies, it is demonstrated that one key feature of many influence situations is that they wear down people’s self-control resources. Resisting persuasion appears to require active self-regulation, and when resources for self-regulation are low, one’s attempts at resistance are more likely to fail. Hence, people’s success in dealing with (unwanted) persuasion depends for an important part on the availability of resources to actively control the self. In line with this notion, the research in this dissertation also demonstrates that when people anticipate persuasion, they become more efficient in allocating their remaining regulatory energy. When resources for self-regulation are low, people start conserving their remaining self-control resources to be able to resist future persuasion, which proves to be a successful (unconscious) strategy to resist a persuasive appeal. By adopting a self-regulation perspective, this dissertation aims to point out a key mechanism responsible for the effectiveness of many social influence situations, thereby contributing to the understanding of the dynamics behind resisting and yielding to persuasion.
High-Molecular-Weight Dextran-Type Exopolysaccharide Produced by the Novel Apilactobacillus waqarii Improves Metabolic Syndrome: In Vitro and In Vivo Analyses

Metabolic syndrome is a leading medical concern that affects one billion people worldwide. Metabolic syndrome is defined by a clustering of risk factors that predispose an individual to cardiovascular disease, diabetes and stroke. In recent years, the apparent role of the gut microbiota in metabolic syndrome has drawn attention to microbiome-engineered therapeutics. Specifically, lactic acid bacteria (LAB) harbors beneficial metabolic characteristics, including the production of exopolysaccharides and other microbial byproducts. We recently isolated a novel fructophilic lactic acid bacterium (FLAB), Apilactobacillus waqarii strain HBW1, from honeybee gut and found it produces a dextran-type exopolysaccharide (EPS). The objective of this study was to explore the therapeutic potential of the new dextran in relation to metabolic syndrome. Findings revealed the dextran’s ability to improve the viability of damaged HT-29 intestinal epithelial cells and exhibit antioxidant properties. In vivo analyses demonstrated reductions in body weight gain and serum cholesterol levels in mice supplemented with the dextran, compared to control (5% and 17.2%, respectively). Additionally, blood glucose levels decreased by 16.26% following dextran supplementation, while increasing by 15.2% in non-treated mice. Overall, this study displays biotherapeutic potential of a novel EPS to improve metabolic syndrome and its individual components, warranting further investigation.

Deciphering the oscillation spectrum of γ Doradus and SPB stars

Context. The space-based Kepler mission provided four years of highly precise and almost uninterrupted photometry for hundreds of γ Doradus stars and tens of slowly pulsating B-type (SPB) stars, finally allowing us to apply asteroseismology to these gravity mode pulsators. Without rotation, gravity modes are equally spaced in period. This simple structure does not hold in rotating stars for which rotation needs to be taken into account to accurately interpret the oscillation spectrum. Aims. We aim to develop a stellar-model-independent method to analyse and interpret the oscillation spectrum of γ Dor and SPB stars. Methods. Within the traditional approximation of rotation, we highlight the possibility of recovering the equidistance of period spacings by stretching the pulsation periods. The stretching function depends on the degree and azimuthal order of gravity modes and the rotation rate of the star. In this new stretched space, the pulsation modes are regularly spaced by the stellar buoyancy radius. Results. On the basis of this property, we implemented a method to search for these new regularities and simultaneously infer the rotation frequency and buoyancy radius. Tests on synthetic spectra computed with a non-perturbative approach show that we can retrieve these two parameters with reasonable accuracy along with the mode identification. In uniformly rotating models of a typical γ Dor star, and for the most observed prograde dipole modes, we show that the accuracy on the derived parameters is better than 5% on both the internal rotation rate and the buoyancy radius. Finally, we apply the method to two stars of the Kepler field, a γ Dor and an SPB, and compare our results with those of other existing methods. Conclusions. We provide a stellar-model-independent method to obtain the near-core rotation rate, the buoyancy radius, and the mode identification from gravity-mode spectra of γ Dor and SPB stars.
Police Ethics in Rural Contexts: A Left Realist Consequentialist View

This article presents crime survey data from the state of West Virginia in the United States showing that, controlling for structural conditions, community atmosphere is significantly related to crime, violence and many other social problems in rural places. These results help identify measurable and achievable progressive desired ends in rural policing, replacing law enforcement outputs (for example, arrests, gun and drug seizures) with safe, strong community outcomes as the summum bonum (i.e, ultimate outcome) of policing. Findings show that interdependent communities where police are partners with residents are the safest, while conflict communities where the police are viewed as adversaries are least safe. These results suggest a left realist consequentialist approach to police ethics to dismantle the hegemony of draconian policies and practices.
How cores grow by pebble accretion I. Direct core growth

Context: Planet formation by pebble accretion is an alternative to planetesimal-driven core accretion. In this scenario, planets grow by accreting cm-to-m-sized pebbles instead of km-sized planetesimals. One of the main differences with planetesimal-driven core accretion is the increased thermal ablation experienced by pebbles. This provides early enrichment to the planet's envelope, which changes the process of core growth. Aims: We aim to predict core masses and envelope compositions of planets that form by pebble accretion and compare mass deposition of pebbles to planetesimals. Methods: We model the early growth of a proto-planet by calculating the structure of its envelope, taking into account the fate of impacting pebbles or planetesimals. The region where high-Z material can exist in vapor form is determined by the vapor pressure. We include enrichment effects by locally modifying the mean molecular weight. Results: In the pebble case, three phases of core growth can be identified. In the first phase, pebbles impact the core without significant ablation. During the second phase, ablation becomes increasingly severe. A layer of high-Z vapor starts to form around the core that absorbs a small fraction of the ablated mass. The rest either rains out to the core or mixes outwards instead, slowing core growth. In the third phase, the vapor inner region expands outwards, absorbing an increasing fraction of the ablated material as vapor. Rainout ends before the core mass reaches 0.6 M_Earth, terminating direct core growth. In the case of icy H2O pebbles, this happens before 0.1 M_Earth. Conclusions: Our results indicate that pebble accretion can directly form rocky cores up to only 0.6 M_Earth, and is unable to form similarly sized icy cores. Subsequent core growth can proceed indirectly when the planet cools, provided it is able to retain its high-Z material.
Morphology and Kinematics of Filaments in the Serpens and Perseus Molecular Clouds

We present H13CO+ (J = 1–0) and HNC (J = 1–0) maps of regions in Serpens South, Serpens Main, and NGC 1333 containing filaments. We also observe the Serpens regions using H13CN (J = 1–0). These dense gas tracer molecular line observations carried out with CARMA have an angular resolution of ∼7″, a spectral resolution of ∼0.16 km s−1, and a sensitivity of 50–100 mJy beam−1. Although the large-scale structure compares well with the Herschel dust continuum maps, we resolve finer structure within the filaments identified by Herschel. The H13CO+ emission distribution agrees with the existing CARMA N2H+ (J = 1–0) maps, so they trace the same morphology and kinematics of the filaments. The H13CO+ maps additionally reveal that many regions have multiple structures partially overlapping in the line of sight. In two regions, the velocity differences are as high as 1.4 km s−1. We identify eight filamentary structures having typical widths of 0.03–0.08 pc in these tracers. At least 50% of the filamentary structures have distinct velocity gradients perpendicular to their major axis, with average values in the range of 4–10 km s−1 pc−1. These findings are in support of the theoretical models of filament formation by 2D inflow in the shock layer created by colliding turbulent cells. We also find evidence of velocity gradients along the length of two filamentary structures; the gradients suggest that these filaments are inflowing toward the cloud core.
