description: This work analyses the temporal coherence and correlation of twin beams generated in a quasi-phase matched nonlinear crystal in a counterpropagating configuration, ranging from the low-gain regime, where counterpropagating photon pairs are generated spontaneously, to the regime of stimulated pair production, close to the MOPO (Mirrorless Optical Parametric Oscillator) threshold. Here we show a critical divergence of the correlation time and slowing down of quantum fluctuations originating from the feedback mechanism responsible of the MOPO threshold.

Erosive Tooth Wear: Prevalence in GERD Patients and Education in US and Canadian Dental Schools
Creators: name: Nguyen Ngoc, Caroline Uyen Khanh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Specific aims were to determine the prevalence of erosive tooth wear (ETW) in gastroesophageal reflux disease (GERD) and control populations after controlling for other known risk factors (diet, medications, salivary flow rate and buffering capacity) and to survey US and Canadian dental schools regarding their teaching of ETW. ETW was determined for subjects recruited (GERD/Control) using the Basic Erosive Wear Examination (BEWE) index. A survey was also sent to all US and Canadian dental education programs. Results showed that prevalence of ETW in GERD subjects was 51.7% versus 18.2% for controls. ETW worsen with age and was the only co-factor investigated that significantly affected ETW. Although 100% of dental schools in the US and Canada taught dental erosion, only 15.3% of respondents could correctly identify clinical signs of dental erosion, showing that diagnosis of this condition remains unclear. Tooth wear index and diet counselling are also underutilized.

SARS-CoV-2 detection by a clinical diagnostic RT-LAMP assay
Creators: name: Poirier, Enzo
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Life Sciences

description: The ongoing pandemic of SARS-CoV-2 calls for rapid and cost-effective methods to accurately identify infected individuals. The vast majority of patient samples is assessed for viral RNA presence by RT-qPCR. Our biomedical research institute, in collaboration between partner hospitals and an accredited clinical diagnostic laboratory, established a diagnostic testing pipeline that has reported on more than 252,000 RT-qPCR results since its commencement at the beginning of April 2020. However, due to ongoing demand and competition for critical resources, alternative testing strategies were sought. In this work, we present a clinically-validated procedure for high-throughput SARS-CoV-2 detection by RT-LAMP in 25 minutes that is robust, reliable, repeatable, sensitive, specific, and inexpensive.

description: Light absorption in graphene causes a large change in electron temperature, due to low electronic heat capacity and weak electron phonon coupling [1-3], making it very attractive as a hot-electron bolometer material. Unfortunately, the weak variation of electrical resistance with temperature has substantially limited the responsivity of graphene bolometers. Here we show that quantum dots of epitaxial graphene on SiC exhibit an extraordinarily high variation of resistance with temperature due to quantum confinement, higher than 430 Mohm/K at 2.5 K, leading to responsivities for absorbed THz power above 10^10 V/W. This is five orders of magnitude higher than other types of graphene hot electron bolometers. The high responsivity combined with an extremely low noise-equivalent power, about 0.2 fW/Hz^0.5 at 2.5K, place the performance of graphene quantum dot bolometers well above commercial cooled bolometers. Additionally, these quantum dot bolometers have the potential for superior performance for operation above 77K.

Microscopic Theory of Traffic Flow Instability Governing Traffic Breakdown at Highway Bottlenecks: Growing Wave of Increase in Speed in Synchronized Flow

Publisher: name: arXiv
Year: 2015
Subjects: subject: Physics and Society (physics.soc-ph)
subject: Cellular Automata and Lattice Gases (nlin.CG)
subject: FOS: Physical sciences

description: We have revealed a growing local speed wave of increase in speed that can randomly occur in synchronized flow (S) at a highway bottleneck. The development of such a traffic flow instability leads to free flow (F) at the bottleneck; therefore, we call this instability as an S$\rightarrow$F instability. Whereas the S$\rightarrow$F instability leads to a local {\it increase in speed} (growing acceleration wave), in contrast, the classical traffic flow instability introduced in 50s--60s and incorporated later in a huge number of traffic flow models leads to a growing wave of a local {\it decrease in speed} (growing deceleration wave). We have found that the S$\rightarrow$F instability can occur only, if there is a finite time delay in driver over-acceleration. The initial speed disturbance of increase in speed (called "speed peak") that initiates the S$\rightarrow$F instability occurs usually at the downstream front of synchronized flow at the bottleneck. There can be many speed peaks with random amplitudes that occur randomly over time. It has been found that the S$\rightarrow$F instability exhibits the nucleation nature: Only when a speed peak amplitude is large enough, the S$\rightarrow$F instability occurs; in contrast, speed peaks of smaller amplitudes cause dissolving speed waves of a local increase in speed(dissolving acceleration waves) in synchronized flow. We have found that the S$\rightarrow$F instability governs traffic breakdown -- a phase transition from free flow to synchronized flow (F$\rightarrow$S transition) at the bottleneck: The nucleation nature of the S$\rightarrow$F instability explains the metastability of free flow with respect to an F$\rightarrow$S Transition at the bottleneck.

Dynamics of decoherence: universal scaling of the decoherence factor

Publisher: name: arXiv
Year: 2015
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study the time dependence of the decoherence factor (DF) of a qubit globally coupled to an environmental spin system (ESS) which is driven across the quantum critical point (QCP) by varying a parameter of its Hamiltonian in time $t$ as $1 -t/τ$ or $-t/τ$, to which the qubit is coupled starting at the time $t \to -\infty$; here, $τ$ denotes the inverse quenching rate. In the limit of weak coupling, we analyze the time evolution of the DF in the vicinity of the QCP (chosen to be at $t=0$) and define three quantities, namely, the generalized fidelity susceptibility $χ_F(τ)$ (defined right at the QCP), and the decay constants $α_1 (τ)$ and $α_2 (τ)$ which dictate the decay of the DF at a small but finite $t$($>0$). Using a dimensional analysis argument based on the Kibble-Zurek healing length, we show that $χ_F(τ)$ as well as $α_1 (τ)$ and $α_2(τ)$ indeed satisfy universal power-law scaling relations with $τ$ and the exponents are solely determined by the spatial dimensionality of the ESS and the exponents associated with its QCP. Remarkably, using the numerical t-DMRG method, these scaling relations are shown to be valid in both the situations when the ESS is integrable and non-integrable and also for both linear and non-linear variation of the parameter. Furthermore, when an integrable ESS is quenched far away from the QCP, there is a predominant Gaussian decay of the DF with a decay constant which also satisfies a universal scaling relation.

description: Background: Recognizing learning styles is important to maximize the educational process and many instruments that are available to investigate learning styles. Objective: To investigate instruments with evidence of validity and reliability most commonly used to evaluate healthcare student learning styles globally. Design: A scoping review of literature. Method: The review was guided by The Joanna Briggs Institute’s recommendations for conducting scoping reviews and the PRISMA (extension for scoping reviews), that is available for access. Data sources: Databases searched included Cumulative Index to Nursing and Allied Health Literature, PubMed, Web of Science, and Scopus. The review's eligibility criteria included fully accessible, written in English, Portuguese or Spanish and used reliable and/or validated instruments to describe health care student learning styles. Data on year of publication, author, country, sample size, age, type of study, the instrument used, and evidence of validation and/or reliability were extracted from the study, analyzed and stored in Microsoft Office Excel spreadsheets. Results: A total of 47 articles were selected for full review, which included cross-sectional, interventional, and longitudinal studies. The most frequently used learning style evaluation instruments were Visual, Aural, Read-Write, and Kinesthetic, Kolb’s Learning Styles Inventory, and the Honey-Alonso Questionnaire. Most instruments were developed based on a theoretical framework and/or model. Conclusion: Eleven instruments were identified with evidence of reliability and validity for assessing undergraduate health care learning styles globally. In general, there is little evidence of the psychometric properties of both measurements. The results of this study underlines the importance of conducting further studies to help researchers make decisions on the best instrument to be used.

description: Here, we report the observation of a hitherto unreported optoelectronic effect, namely a light-induced diode-like response in multi-layered MoSe$_2$ field-effect transistors whose sense of current rectification is controllable through a gate voltage. We argue, through numerical simulations, that this behavior results from the difference in the size of the Schottky barriers between drain and source metal contacts. Each barrier can be modeled as a Schottky diode but with opposite senses of current rectification between them, with the diode response resulting from the light induced promotion of photo-generated carriers across the smaller barrier. The back gate voltage controls the sense of current rectification by modulating the relative amplitude between them. This effect, which gives rise to a novel type of optoelectronic switch, also yields a photovoltaic response. Hence, it could provide an alternative to PN-junctions when harvesting photovoltaic currents from transition metal dichalcogenides. We argue that the photovoltaic efficiency associated to this effect could be increased by just increasing the relative asymmetry between both Schottky barriers. We also suggest that this new electro-optical effect has potential for technological applications.

description: Aims: To compare the microbiomes of placenta and umbilicus samples from 44 women presenting periodontal diseases who experienced full term (FTB, n=22) and preterm births (PTB; <35 weeks, n=22), as well as, the level of maternal subgingival periodontal species in each group pre and post-partum. Materials and methods: Clinical and demographic data, subgingival plaque samples, as well as, placenta and umbilical cord tissues samples were obtained. The microbial content of the tissue samples were analyzed using 16rRNA sequencing, while subgingival biofilm samples were analyzed using checkerboard DNA-DNA hybridization method. Results: Most abundant phylum in both placenta and umbilicus samples was Firmicutes. Most abundant genera in both placenta and umbilicus samples was Veillonella. Some of the most common species detected were Neisseria elongata, Pyramidobacter piscolens, and Gemella morbillorum. Conclusion: PTB and FTB exhibit distinct umbilical microbiomes. PTB samples are more heavily colonized by oral pathogenic taxa, whereas FTB specimens had higher levels of commensal organisms.

description: Imaging and spectroscopy at (sub-)millimeter wavelengths are key frontiers in astronomy and cosmology. Large area spectral surveys with moderate spectral resolution (R=50-200) will be used to characterize large scale structure and star formation through intensity mapping surveys in emission lines such as the CO rotational transitions. Such surveys will also be used to study the SZ effect, and will detect the emission lines and continuum spectrum of individual objects. WSPEC is an instrument proposed to target these science goals. It is a channelizing spectrometer realized in rectangular waveguide, fabricated using conventional high-precision metal machining. Each spectrometer is coupled to free space with a machined feed horn, and the devices are tiled into a 2D array to fill the focal plane of the telescope. The detectors will be aluminum Lumped-Element Kinetic Inductance Detectors (LEKIDs). To target the CO lines and SZ effect, we will have bands at 135-175 GHz and 190-250 GHz, each Nyquist-sampled at R~200 resolution. Here we discuss the instrument concept and design, and successful initial testing of a WR10 (i.e. 90 GHz) prototype spectrometer. We recently tested a WR5 (180 GHz) prototype to verify that the concept works at higher frequencies, and also designed a resonant backshort structure that may further increase the optical efficiency. We are making progress towards integrating a spectrometer with a LEKID array and deploying a prototype device to a telescope for first light.

description: M-dwarf stars are generally considered favourable for rocky planet detection. However, such planets may be subject to extreme conditions due to possible high stellar activity. The goal of this work is to determine the potential effect of stellar cosmic rays on key atmospheric species of Earth-like planets orbiting in the habitable zone of M-dwarf stars and show corresponding changes in the planetary spectra. We build upon the cosmic rays model scheme of Grenfell et al. (2012), who considered cosmic ray induced NOx production, by adding further cosmic ray induced production mechanisms (e.g. for HOx) and introducing primary protons of a wider energy range (16 MeV - 0.5 TeV). Previous studies suggested that planets in the habitable zone that are subject to strong flaring conditions have high atmospheric methane concentrations, while their ozone biosignature is completely destroyed. Our current study shows, however, that adding cosmic ray induced HOx production can cause a decrease in atmospheric methane abundance of up to 80\%. Furthermore, the cosmic ray induced HOx molecules react with NOx to produce HNO$_3$, which produces strong HNO$_3$ signals in the theoretical spectra and reduces NOx-induced catalytic destruction of ozone so that more than 25\% of the ozone column remains. Hence, an ozone signal remains visible in the theoretical spectrum (albeit with a weaker intensity) when incorporating the new cosmic ray induced NOx and HOx schemes, even for a constantly flaring M-star case. We also find that HNO$_3$ levels may be high enough to be potentially detectable. Since ozone concentrations, which act as the key shield against harmful UV radiation, are affected by cosmic rays via NOx-induced catalytic destruction of ozone, the impact of stellar cosmic rays on surface UV fluxes is also studied.

description: There is evidence in the literature that bariatric surgery offers improvement, in the short term, for the patient with obesity, whose clinical treatment was not effective, leading to an increase in the physical, psychological and social quality of life. However, long-term follow-up is necessary in order to check for improvements and probable complications. Regardless of the surgical approach (open or laparoscopic), among the postoperative complications that can affect the patient, surgical site infection (SSI) stands out. Thus, the focus of this integrative review is directed towards SSI, an important complication in the postoperative morbidity of bariatric surgery, and it is necessary to identify the risk factors for the development of this type of infection, to increase the results of the assistance provided by the multidisciplinary health team.

description: The NASA New Horizons spacecraft flies past Pluto on July 14, 2015, carrying two instruments that detect charged particles. Pluto has a tenuous, extended atmosphere that is escaping the weak gravity of the planet. The interaction of the solar wind with the escaping atmosphere of Pluto depends on solar wind conditions as well as the vertical structure of the atmosphere. We have analyzed Voyager 2 particles and fields measurements between 25 and 39 AU and present their statistical variations. We have adjusted these predictions to allow for the declining activity of the Sun and solar wind output. We summarize the range of SW conditions that can be expected at 33 AU and survey the range of scales of interaction that New Horizons might experience. Model estimates for the solar wind stand-off distance vary from approximately 7 to 1000 RP with our best estimate being around 40 RP (where we take the radius of Pluto to be RP=1184 km).

Thermal Inactivation of Viable Geobacillus Stearothermophilus and Bacillus Atrophaeus Spores in a Bench-Scale Landfill Gas Flare
Creators: name: Tufts, Jenia A.

Year: 2011

description: A bench-scale, landfill flare system was designed and built to test the potential for heat-resistant spores to survive the flaring process and enter the environment. The residence times and temperatures of the flare were characterized and compared to full-scale systems. Experiments were conducted using Geobacillus stearothermophilus and Bacillus atrophaeus spores as surrogates for Bacillus anthracis. Spore solutions were aerosolized, dried, and sent through the bench-scale system. Sampling was conducted downstream of the flare using a bioaerosol collection device. The samples were cultured, incubated for seven days, and assessed for viability. Results showed that the bench-scale, landfill flare system was comparable to a full-scale combustor flare with a single-orifice diffusion burner. All spores of G. stearothermophilus and B. atrophaeus were inactivated in the bench-scale system, suggesting that spores that pass through the flare in a full-scale system will become inactivat

NOTES TOWARDS A SPATIAL READING OF MARX’S FRAGMENT ON MACHINES
Creators: name: Sandell, John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: This thesis contributes to the current project of developing new critical urban theory in response to the economic, social, and technological transformations of the early 21st century. More specifically, it focuses on a recent metropolitanization of post-Workerist theories of cognitive capitalism by arguing for a need to more carefully interrogate the underlying base of such theories and its implications for the contemporary theorization of cities. In particular, a section in Karl Marx’s notebooks known as the Fragment on Machines is identified as a key text that provides the foundation for contemporary theories of cognitive and post-industrial capitalism. Drawing on a largely forgotten book by eminent spatial theorist Henri Lefebvre, I suggest the importance of reading and thinking Marx’s Fragment in spatial terms. Introducing the problem of space, I argue, provides an important corrective to current attempts to urbanize theories of cognitive capitalism.

description: Soft behaviour of closed string amplitudes involving dilatons, gravitons and anti-symmetric tensors, is studied in the framework of bosonic string theory. The leading double soft limit of gluons is analysed as well, starting from scattering amplitudes computed in the open bosonic string. Field theory expressions are then obtained by sending the string tension to infinity. The presented results have been derived in the papers of Ref.[1].

Subjects: subject: Medicine and Health Sciences

description: A scoping review to map the available evidence will be undertaken, informing the revision of the Australian national clinical practice guidelines for the assessment and diagnosis of fetal alcohol spectrum disorder (FASD). Review question: What broader factors (i.e., outside of the diagnostic criteria requirements) that could be considered as part of a holistic assessment process when considering fetal alcohol spectrum disorder as one possible outcome? For example, this could include experiences of neglect or trauma, cultural appropriateness, social determinants of health, physical health and wellbeing factors.
Reheating of the Universe as holographic thermalization

description: Assuming gauge/gravity correspondence we study reheating of the Universe using its holographic dual. Inflaton decay and thermalisation of the decay products correspond to collapse of a spherical shell and formation of a blackhole in the dual anti-de Sitter (AdS) spacetime. The reheating temperature is computed as the Hawking temperature of the developed blackhole probed by a dynamical boundary, and is determined by the inflaton energy density and the AdS radius, with corrections from the dynamics of the shell collapse. For given initial energy density of the inflaton field the holographic model gives significantly lower reheating temperature than the instant reheating scenario, while it is shown to be safely within phenomenological bounds.

description: Dysmenorrhea is pain and discomfort associated with menstruation. It is a commonly reported condition among women in their reproductive age. The prevalence rate varies from 16% to 91% in women in their reproductive age. There are two main types of dysmenorrhea as primary and secondary. Secondary dysmenorrhea is caused by underline disease condition. Primary dysmenorrhea is defined as cramping pain of lower abdominal area before and during menstruation without any underline pelvic pathology. Primary dysmenorrhea affects 90% of adolescent girls and 50% of menstruating women. The increased or abnormal uterine activity due to high production and release of prostaglandins is the primary factor for the condition. The main clinical feature is cramping pain in lower abdominal area and it can radiate to back and thigh areas. Primary dysmenorrhea can adversely affect to the normal lifestyle. Participation restriction for social, work and academic events, increased healthcare cost and restriction to daily activities are few adverse effects of the condition. There are various treatment options are available for the condition such as medications (oral contraceptives, non-steroidal anti-inflammatory), Acupuncture, exercises, herbal remedies, massage, taping and life style modifications. There are few research studies have conducted to assess effect of taping on menstrual pain. But there is lack of systematic review in this field. Therefore, this systematic review aims to review available literature of effect of taping on menstrual pain. This will look at the effect of taping techniques for menstrual pain, both as a 'therapy alone' and as a 'combined therapy' along with other treatments.
