description: The modern organization of the educational process requires scientists to study in depth its pedagogical and psychological foundations, theory and practice, to reconsider educational technologies and methods, worldviews in accordance with modern requirements, to make a breakthrough in spiritual and moral values. Therefore, new education is aimed at the formation of a person with new knowledge and skills, high creativity, ability to solve important problems as a result of independent research, and the ability to think. Research skills are required for a foreign language teacher. According to it, the training of subject teachers is formed in higher education institutions. Based on this ability, a teacher of a foreign language school can scientifically look at each pedagogical phenomenon, make scientific predictions, design and plan experiments, as well as collect best practices in their practice, analyze them on a theoretical and practical basis and implement them in school life.

description: In 2019, the Network of the National Library of Medicine embarked on a process to update a course that aimed to 1) teach participants how to evaluate quality health websites for nurses; 2) enable participants to describe and evaluate quality nursing resources available on the internet; and 3) demonstrate searches for nursing literature in PubMed. The curriculum development team further refined these objectives. The new course would enable participants to connect National Library of Medicine resources to the needs of nursing and allied health professionals. After taking the course, participants would be able to list the ways librarians can support the information needs of their nursing and allied health audiences. The NNLM curriculum development team met from November 2019 through December 2020 to develop a course that would be launched in early 2021. In the kick-off meeting, the team agreed to investigate needs and best practices for librarians teaching nursing and allied health professionals. Members of the team divided up course development tasks. They reconvened bimonthly to share relevant information resources, sharpen the learning objectives, and share ideas for course activities such as readings, quizzes, and written assignments. The result is a three-week asynchronous course that is designed for library staff who support, or who want to support, nursing and allied health professionals. In Week One, participants learn about the information needs of nursing and allied health professionals. Week Two introduces participants to relevant information resources. Week Three asks participants to apply learning through creating and sharing a professional development plan. We gathered evaluation data after the pilot launch in December 2020 and the three sessions taught in early 2021. We will address participant needs for better navigation and more time to complete the professional development plan. We hope to offer the course again in Summer 2021.

description: We have generated frequency combs spanning 0.5 to 20 GHz in superconducting half wave resonators at T=3 K. Thin films of niobium-titanium nitride enabled this development due to their low loss, high nonlinearity, low frequency dispersion, and high critical temperature. The combs nucleate as sidebands around multiples of the pump frequency. Selection rules for the allowed frequency emission are calculated using perturbation theory and the measured spectrum is shown to agree with the theory. The sideband spacing is measured to be accurate to 1 part in 10 million. The sidebands coalesce into a continuous comb structure that has been observed to cover at least 6 octaves in frequency.

description: Region 7 priority areas serve to focus and inform our outreach, services, and resources. These areas guide the implementation of local and regional programming.

The Pioneer Library System in Canandaigua, NY contacted Region 7 after several area librarians completed the NNLM Moodle course "Beyond the Binary". They requested a workshop based on the course. The workshop would be offered as part of a standing training session for public librarians in rural New York. Coordinators Margot Malachowski and Bennie Finch attended the training session. Margot was the lead instructor and Bennie assisted with the chat discussion. After attending the session, public librarians would be able to: List four key points regarding the health information needs of the LGBTQIA+ community; List three concepts for providing a welcoming environment for sexual and gender minorities; and identify three resources for providing health information regarding sexual and gender minorities.

During the "Beyond the Binary Workshop", we introduced the National Library of Medicine and the Network of the National Library of Medicine. We explained that we would be covering the highlights of the 4-week "Beyond the Binary" Moodle course. We encouraged participants to share what they were comfortable sharing and to ask what they wanted to ask. The LGBTQIA+ community faces many barriers in accessing healthcare. Consequently, some in the LGBTQIA+ community do not regularly access appropriate and timely care that they need. This workshop discussed cultural humility. Humility encourages self-reflection as we learn about the cultures of any community that is not our own.

We covered four key points: delays in getting health care; insensitive health care providers; stress-related illnesses; and difficulty finding culturally sensitive materials. Three concepts for providing a welcoming environment for sexual and gender minorities are: to become comfortable with using they/them pronouns as singular; display LGBTQIA+ friendly symbols, such as rainbow flags and including your pronouns in announcements and email signatures; and use inclusive images in library materials, such as the images from the Gender Spectrum Collection.

We did live searching for health information in these resources: MedlinePlus: LGBTQ+ Health Topics Page; Centers for Disease Control and Prevention (CDC): Lesbian, Gay, Bisexual and Transgender Health, including Youth; and Fenway Health: National LGBT Health Education Center.
New three-dimensional strain-rate potentials for isotropic porous metals: role of the plastic flow of the matrix

description: At present, modeling of the plastic response of porous solids is done using stress-based plastic potentials. To gain understanding of the combined effects of all invariants for general three-dimensional loadings, a strain-rate based approach appears more appropriate. In this paper, for the first time strain rate-based potentials for porous solids with Tresca and von Mises, matrices are obtained. The dilatational response is investigated for general 3-D conditions for both compressive and tensile states using rigorous upscaling methods. It is demonstrated that the presence of voids induces dependence on all invariants, the noteworthy result being the key role played by the plastic flow of the matrix on the dilatational response. If the matrix obeys the von Mises criterion, the shape of the cross-sections of the porous solid with the octahedral plane deviates slightly from a circle, and changes very little as the absolute value of the mean strain rate increases. However, if the matrix behavior is described by Tresca's criterion, the shape of the cross-sections evolves from a regular hexagon to a smooth triangle with rounded corners. Furthermore, it is revealed that the couplings between invariants are very specific and depend strongly on the particularities of the plastic flow of the matrix.

description: Certain regions of Saturn's rings exhibit periodic opacity variations with characteristic radial wavelengths of up to a few hundred meters that have been attributed to viscous overstabilities. The Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft observed two stellar occultations of the star gamma Crucis that had sufficient resolution to discern a sub-set of these periodic patterns in a portion of the A ring between 124,000 and 125,000 km from Saturn center. These data reveal that the wavelengths and intensities of the patterns vary systematically across this region, but that these parameters are not strictly determined by the ring's average optical depth. Furthermore, our observations indicate that these opacity variations have an azimuthal coherence scale of around 3000 km.

Year: 2011

description: Objective: In May 2009, after considering short and long-term maternal/child outcomes, the Institute of Medicine (IOM) revised recommendations for gestational weight gain (GWG); however preeclampsia was dismissed due to insufficient evidence. Our objective was to evaluate preeclampsia risk by angiogenic-biomarker profile by both BMI and GWGadherence. Given numerous studies showing adipose tissue's ability to stimulate angiogenesis, we hypothesized that overweight/obese (OW-OB) women and over-gainers (OG) would have altered angiogenic profiles as compared to underweight/normal-weight (UN) women and under-/appropriate-gainers (U-AG), respectively.

Methods: Between 5/04-1/06, serial serum specimens collected from 94 women at high preeclampsia risk between 22-36 weeks. Soluble fms-like tyrosine kinase-1 (sFlt1), placental growth factor (PlGF) and soluble endoglin (sEng) measured by ELISA. BMI and GWG adherence categories determined by 1990 IOM recommendations. Within-women correlation and right-skewness handled by estimating linear mixed models for ln-transformed biomarkers and then exponentiating on ln scale (i.e.geometric means). T-test compared means in 3 windows.

Results: Analytic sample included 82 subjects (342 specimens) without multiples or pregnancy-related hypertension diagnosis. Mean sFlt1 lower in all windows in OW-OB compared to U-N - significant only at 22-26wks [506.2 (95% CI 438.1-584.9) vs 745.5 (95% CI 595.9-932.6) p=0.04] and in OG compared to U-AG with significant comparisons (p=0.05) [22-26wks: 492.1 (95% CI 420.1-576.3) vs 691.3 (95% CI 574.0-832.6); 27-30 wks: 570.1 (95% CI 488.1-665.9) vs 788.8 (95% CI 656.8-947.4)]. Mean PIGF lower in all windows in OW-OB compared to U-N [22-26wks: 430.5 (95% CI 359.0-516.3) vs 588.6 (95% CI 444.3-779.7) p=0.06; 27-30wks: 475.8 (95% CI 398.7-567.8) vs 811.8 (95% CI 614.3-1072.9) p=0.005; 31-36wks: 428.5 (95% CI 358.0-513.0) vs 724.6 (95% CI 548.5-957.1) p=0.01] and in OG compared to U-AG with no significant comparisons. Mean ratio [(sFlt1+sEng):PIGF] trended higher in OW-OB compared to U-N women at 27-30 and 31-36 wks and in OG compared to UAG at 31-36wks; however no windows with significant comparisons.

Conclusion: Findings suggest trends that OW-OB BMI and excessive GWG associated with angiogenic biomarker profiles consistent with higher preeclampsia risk. Exploratory study limited by small numbers. BMI and GWG as potentially modifiable factors merit furtherinvestigation for preeclampsia risk alteration.

description: We analyze general laws of continuous-variable entanglement dynamics during the deterministic attenuation and amplification of the physical signal carrying the entanglement. These processes are inevitably accompanied by noises, so we find fundamental limitations on noise intensities that destroy entanglement of gaussian and non-gaussian input states. The phase-insensitive amplification $Φ_1 \otimes Φ_2 \otimes \ldots Φ_N$ with the power gain $κ_i \ge 2$ ($\approx 3$ dB, $i=1,\ldots,N$) is shown to destroy entanglement of any $N$-mode gaussian state even in the case of quantum limited performance. In contrast, we demonstrate non-gaussian states with the energy of a few photons such that their entanglement survives within a wide range of noises beyond quantum limited performance for any degree of attenuation or gain. We detect entanglement preservation properties of the channel $Φ_1 \otimes Φ_2$, where each mode is deterministically attenuated or amplified. Gaussian states of high energy are shown to be robust to very asymmetric attenuations, whereas non-gaussian states are at an advantage in the case of symmetric attenuation and general amplification. If $Φ_1 = Φ_2$, the total noise should not exceed $\frac{1}{2} \sqrt{κ^2+1}$ to guarantee entanglement preservation.

description: [ABRIDGED] We report the results of a $J$ band search for cloud-related variability in the atmospheres of 62 L4-T9 dwarfs using the Du Pont 2.5-m telescope at Las Campanas Observatory and the Canada France Hawaii Telescope on Mauna Kea. We find 9 of 57 objects included in our final analysis to be significantly variable with >99% confidence, 5 of which are new discoveries. In our study, strong sinusoidal signals (peak-to-peak amplitudes >2%) are confined to the L/T transition (4/16 objects with L9-T3.5 spectral types and 0/41 objects for all other spectral types). The probability that the observed occurrence rates for strong variability inside and outside the L/T transition originate from the same underlying true occurrence rate is excluded with >99.7% confidence. These observations suggest that the settling of condensate clouds below the photosphere in brown dwarf atmospheres does not occur in a spatially uniform manner. Rather, the formation and sedimentation of dust grains at the L/T transition is coupled to atmospheric dynamics, resulting in highly contrasting regions of thick and thin clouds and/or clearings. Outside the L/T transition we identify 5 weak variables (peak-to-peak amplitudes of 0.6%-1.6%). Excluding L9-T3.5 spectral types, we infer that $60^{+22}_{-18}$% of targets vary with amplitudes of 0.5%$-$1.6%, suggesting that surface heterogeneities are common among L and T dwarfs. Our survey establishes a significant link between strong variability and L/T transition spectral types, providing evidence in support of the hypothesis that cloud holes contribute to the abrupt decline in condensate opacity and 1 micron brightening observed in this regime. More generally, fractional cloud coverage is an important model parameter for brown dwarfs and giant planets, especially those with L/T transition spectral types and colors.

description: The C II] feature at ~2325 Angstrom is very prominent in the spectra of T Tauri stars (TTSs). This feature is a quintuplet of semiforbidden transitions excited at electron temperatures around 10,000 K that, together with the nearby Si II] and Fe II] features, provides a reliable optically thin tracer for accurate measurement of the plasma properties in the magnetospheres of TTSs. The spectra of 20 (out of 27) TTSs observed with the Space Telescope Imaging Spectrograph (STIS) on board the Hubble Space Telescope (HST) have good enough signal to noise ratio (S/N) at the C II] wavelength. For these stars we have determined electron densities (ne) and temperatures (Te) in the line emission region as well as the profile broadening (sigma). For most of the stars in the sample (17) we obtain 10^{4.1} < Te < 10^{4.5} K and 10^{8} < ne < 10^{12} cm^{-3}. These stars have suprathermal line broadening (35 < sigma < 165 km s^{-1}), except TW Hya and CY Tau with thermal line broadening. Both C II] line luminosity and broadening are found to correlate with the accretion rate. Line emission seems to be produced in the magnetospheric accretion flow, close to the disk. There are three exceptions: DG Tau, RY Tau and FU Ori. The line centroids are blueshifted indicating that the line emission in these three stars is dominated by the outflow.

description: We study the relation between stellar ages and vertical velocity dispersion (the age-velocity relation, or AVR) in a sample of seven simulated disc galaxies. In our simulations, the shape of the AVR for stars younger than 9 Gyr depends strongly on the merger history at low redshift, with even 1:10 - 1:15 mergers being able to create jumps in the AVR (although these jumps might not be detectable if the errors on stellar ages are on the order of 30%). For galaxies with a quiescent history at low redshift, we find that the vertical velocity dispersion rises smoothly for ages up to 8-9 Gyr, following a power law with a slope of ~0.5, similar to what is observed in the solar neighbourhood by the Geneva-Copenhagen Survey. For these galaxies, we show that the slope of the AVR is not imprinted at birth, but is the result of subsequent heating. By contrast, in all our simulations, the oldest stars form a significantly different population, with a high velocity dispersion. These stars are usually born kinematically hot in a turbulent phase of intense mergers at high redshift, and also include some stars accreted from satellites. This maximum in velocity dispersion is strongly decreased when age errors are included, suggesting that observations can easily miss such a jump with the current accuracy of age measurements.

description: Trata-se de um estudo de revisão sobre as descobertas inovadoras acerca da biopatia do câncer desenvolvidas pelo médico psiquiatra austríaco Wilhelm Reich (1897-1957). Como objetivo geral, buscou-se mapear os escritos de Reich sobre o câncer e sua etiologia, assim como os possíveis mecanismos preventivos e de “cura”; como objetivo específico, buscou-se identificar e analisar os estudos realizados tendo como base a teoria de Reich, atualizando o pensamento reichiano acerca da biopatia do câncer a partir de extensa e sistemática revisão bibliográfica (nacional e internacional). Conclui-se que as formulações reichianas acerca da temática têm gerado estudos inovadores, replicação de experimentos originais com modernos métodos de controle, bem como práticas complementares em tratamentos oncológicos ao redor do mundo.

description: The magnetic response expected from a state characterized by rotating antiferromagnetism in a neutron-scattering experiment is calculated. We predict the occurrence of a peak at the frequency of the rotation of the rotating antiferromagnetic order parameter. The doping dependence of this frequency is very similar to that of the frequency of the magnetic resonance observed in the neutron-scattering experiments for the hole-doped high-$T_C$ cuprates. This leads us to propose the rotating antiferromagnetism as a possible mechanism for this magnetic resonance. We conclude that while the magnitude of the rotating antiferromagnetic order parameter was previously proposed to be responsible for the pseudogap and the unusual thermodynamic and transport properties, the phase of the rotating order parameter is proposed here to be responsible for the unusual magnetic properties of the high-$T_C$ copper-oxide superconductors.

description: We explore a new type of entropic mechanism for generating density perturbations in a contracting phase in which there are two scalar fields, but only one has a steep negative potential. This first field dominates the energy density and is the source of the ekpyrotic equation of state. The second field has a negligible potential, but its kinetic energy density is coupled to the first field with a non-linear sigma-model type interaction. We show that for any ekpyrotic equation of state it is possible to choose the potential and the kinetic coupling such that exactly scale-invariant (or nearly scale-invariant) entropy perturbations are produced. The corresponding background solutions are stable, and the bispectrum of the entropy perturbations vanishes as no non-Gaussianity is produced during the ekpyrotic phase. Hence, the only contribution to non-Gaussianity comes from the non-linearity of the conversion process during which entropic perturbations are turned into adiabatic ones, resulting in a local non-Gaussianity parameter $f_{NL} \sim 5$.

description: We study seven simulated disc galaxies, three with a quiescent merger history, and four with mergers in their last 9 Gyr of evolution. We compare their structure at z=0 by decomposing them into "mono-age populations" (MAPs) of stars within 500 Myr age bins. All studied galaxies undergo a phase of merging activity at high redshift, so that stars older than 9 Gyr are found in a centrally concentrated component, while younger stars are mostly found in discs. We find that most MAPs have simple exponential radial and vertical density profiles, with a scale-height that typically increases with age. Because a large range of merger histories can create populations with simple structures, this suggests that the simplicity of the structure of mono-abundance populations observed in the Milky Way by Bovy et al. (2012b,c) is not necessarily a direct indicator of a quiescent history for the Milky Way. Similarly, the anti-correlation between scale-length and scale-height does not necessarily imply a merger-free history. However, mergers produce discontinuities between thin and thick disc components, and jumps in the age-velocity relation. The absence of a structural discontinuity between thin and thick disc observed in the Milky Way would seem to be a good indicator that no merger with a mass ratio larger than 1:15-1:10 occurred in the last 9 Gyr. Mergers at higher redshift might nevertheless be necessary to produce the thickest, hottest components of the Milky Way's disc.

description: Case Diagnosis: Lyme Arthritis

Case Description: Patient 1 is a 26 year old male who presented in March with severe right knee pain and swelling for two weeks. He had a similar episode a month prior, but it resolved. The second episode progressed with pain from knee to foot and numbness on top of the foot. He had no known history of tick bites, travel, or trauma, but endorsed contact with a dog. On physical exam, he had a right knee effusion with limited ROM, diffuse joint line tenderness, positive McMurray’s, and pain with ligamentous testing. Synovial fluid of the joint showed WBC count 44,467 and was positive for Lyme. He was treated with doxycycline. MRI findings were limited to ACL laxity and inflammation.

Patient 2 is a 24 year old male who presented in December with progressive right knee and calf pain for one week. He had been fishing in the woods a few weeks prior with no trauma. Joint aspiration showed a positive Lyme PCR and WBC count 37,520, and he was treated with doxycycline. Aspiration was repeated for recurrent effusion, and an MRI was done due to persistent pain. MRI showed bone contusion, ACL laxity, and inflammation.

Discussions: Lyme disease is transmitted by Ixodes scapularis ticks, which appear in late spring and early summer; however,Lyme arthritis may occur during any season. Ticks infected with the spirochete B. burgdorferi are primarily found in the Northeastern and upper Midwestern US. B. burgdorferi strains of Lyme often disseminate to joints, tendons, or bursae early in infection.Lyme arthritis presents later, with an adaptive immune response that results in spirochetal killing.

Conclusions: Lyme arthritis can present at any time of year, and clinical suspicion in endemic regions should remain high even without a known history of tick exposure or erythema migrans rash.

description: We conduct kinematic analysis of the SDSS spectra of 568 obscured luminous quasars, with the emphasis on the kinematic structure of the [OIII]5007 emission line. [OIII] emission tends to show blueshifts and blue excess, which indicates that at least part of the narrow-line gas is undergoing an organized outflow. The velocity width containing 90% of line power ranges from 370 to 4780 km/sec, suggesting outflow velocities up to 2000 km/sec. The velocity width of the [OIII] emission is positively correlated with the radio luminosity among the radio-quiet quasars. We propose that radio emission in radio-quiet quasars is due to relativistic particles accelerated in the shocks within the quasar-driven outflows; star formation in quasar hosts is insufficient to explain the observed radio emission. The median radio luminosity of the sample of nu L_nu[1.4GHz] = 10^40 erg/sec suggests a median kinetic luminosity of the quasar-driven wind of L_wind=3x10^44 erg/sec, or about 4% of the estimated median bolometric luminosity L_bol=8x10^45 erg/sec. Furthermore, the velocity width of [OIII] is positively correlated with mid-infrared luminosity, which suggests that outflows are ultimately driven by the radiative output of the quasar. As the outflow velocity increases, some emission lines characteristic of shocks in quasi-neutral medium increase as well, which we take as further evidence of quasar-driven winds propagating into the interstellar medium of the host galaxy. None of the kinematic components show correlations with the stellar velocity dispersions of the host galaxies, so there is no evidence that any of the gas in the narrow-line region of quasars is in dynamical equilibrium with the host galaxy. Quasar feedback appears to operate above the threshold luminosity of L_bol=3x10^45 erg/sec.

description: Objectives: Pre-operative physical therapy has been shown to reduce post-acute care service utilization. Shifting rehabilitation to the presurgical period, referred to as prehabilitation, could result in reduced recovery time and cost. Limited access to physical therapy may prevent patients from achieving the benefits, and a standard set of independent exercises may be an alternative. We aim to assess the feasibility of an independent exercise program as a pre-surgical intervention for total hip and knee replacement.

Design: Participants were taught two exercises for hip or knee arthritis at least one week prior to surgery and instructed to perform them independently at home. Subjects were contacted three days to one month post-operatively and surveyed about discharge, frequency of exercise, and living status of alone or with others. No adverse effects were reported. Additional information was collected from the subjects’chart including age, BMI, and sex. Discharge outcomes were compared with pre-existing independent factors using univariate and multivariate analyses.

Results: A total of 80 subjects were followed with a home discharge rate of 78.75%. Univariate analyses showed that the presence of other people in the home showed a slight, but non-significant, association with differences of discharge destination. 82.1%-83.3% of patients who live with others were discharged home versus 57.1% of patients living alone (LR chi-square: 3.84, p=0.15). Multivariate analyses showed a slight, but non-significant, association between frequency of prehabilitation and discharge destination (OR=1.212; 95% CI, 0.960-1.530). BMI showed no associated difference in discharge destination.

Conclusions: Increased frequency of prehabilitation and presence of others at home showed slight associations with increased discharges to home, but were non-significant. Increased exposure to prehabilitation (duration times frequency) trends toward more frequent home discharge. Independently performed prehabilitation may be offered as an alternative pre-surgical intervention with likely little to no adverse effect. Larger numbers are needed to determine likelihood of discharge home.

description: Case Diagnosis: Our patient experienced worsening left foot neuropathy following chemotherapy and radiation treatment for sarcoma.

Case Description: A 24-year-old man underwent local resection of a 12cm x 8cm x 14.5cm rhabdomyosarcoma in the left vastus lateralis. Then, he was treated with vincristine for 40 weeks and radiation to the left lateral thigh with a maximum dose of 50.4 Gy. The sciatic nerve was outside the target area and received a lower dose. While undergoing chemotherapy, the patient experienced bilateral dysesthesias in his fingertips and feet. He had no history of neuropathy prior to treatment. After chemotherapy was completed, these symptoms subsided in all extremities except the left foot, which developed atraumatic plantar flexion and dorsiflexion weakness, great toe extensor and flexor weakness, decreased sensation in the distal left toe to the metatarsal. Electromyography and needle conduction studies demonstrated left worse than right polyneuropathy mainly affecting the tibial and peroneal motor nerves. There was no clear evidence of a single nerve compressive lesion and repeat scans of the thigh showed no new lesion. Given the presence of milder nerve abnormalities on the right in addition to left sided weakness, the cause is likely multifactorial and temporally related to cancer treatments.

Discussions: Persistent or worsening features may appear in patients who received vincristine despite termination of treatment. The pattern is typically sensorimotor; however, this patient demonstrates mainly motor abnormalities. The left worse than right pattern could suggest radiation-induced neuropathy, but no myokymic potentials were seen. Myokymic potentials are common in radiation neuropathy, although their absence does not rule it out. Treatment included physical therapy, gabapentin, and an ankle foot orthosis.

Conclusions: Fourteen months after completing radiation and seven months after completing chemotherapy (seven months after symptom onset), the patient’s symptoms are markedly improved. This case demonstrates that neuropathy after treatment in sarcoma patients may be multifactorial.
