Online Mindfulness-Based Cancer Recovery Program for People Living with Cancer in Alberta: A Randomized Wait-List Controlled Trial
Creators: name: Zernicke, Kristin
Publisher: name: Graduate Studies

Subjects: Psychology--Clinical

description: Objective Through a randomized treatment-as-usual (TAU) wait-list controlled trial, the current studies examined the feasibility and impact of an online “real-time” synchronous Mindfulness-Based Cancer Recovery (MBCR) group program for distressed people diagnosed with cancer, who did not have access to in-person MBCR. Sub-analyses combined both the immediate and TAU wait-list groups to evaluate potential medical and physical demographic effects on participant mindfulness facets and symptom subscale scores to determine which participants improved most after the online MBCR intervention. Methods Sixty-two men and women exhibiting moderate-to-high distress were randomized to either immediate online MBCR or to wait for the next available program. Intent-to-treat mixed-model analyses for repeated measures were conducted. Subsequent, pre-post linear mixed model analysis was conducted on all participants who completed MBCR, and standardized change scores were calculated for subscales of mood and stress symptom measures. Results Feasibility targets for recruitment and retention were achieved. Participants were satisfied and would recommend online MBCR to other cancer survivors. Completion rates were comparable to in-person MBCR. Improvements and moderate effect sizes were reported in the online MBCR group relative to a TAU wait-list following MBCR for total scores of mood disturbance, stress symptoms, spirituality, and mindfully acting with awareness. Significant main effects of time were observed for posttraumatic growth and remaining mindfulness facets. Sub-analyses revealed younger participants had greater reductions in stress symptoms, increases in spirituality, and non-reactivity to experience over time. Over time, men experienced significantly greater posttraumatic growth than women. Subscale analyses of mood disturbance and symptoms of stress revealed greatest relative improvements in the subscales of Vigor, Fatigue, and Sympathetic Nervous System Arousal. Conclusions Results provided evidence for the feasibility and efficacy of an online adaptation of MBCR, facilitating reduction of mood disturbance and stress symptoms, and increasing participant-reported spirituality and mindfully acting with awareness. Online MBCR also reduced the negative physical impact of distress by improving energy levels and inducing relaxation. Future study is warranted using larger active control RCT designs. Programs utilizing similar technology could potentially improve access to other specialized psychosocial programs.

description: We use the galaxy angular power spectrum at $z\sim0.5-1.2$ from the Canada-France-Hawaii-Telescope Legacy Survey Wide fields (CFHTLS-Wide) to constrain separately the total neutrino mass $\sum{m_ν}$ and the effective number of neutrino species $N_{\rm{eff}}$. This survey has recently benefited from an accurate calibration of the redshift distribution, allowing new measurements of the (non-linear) matter power spectrum in a unique range of scales and redshifts sensitive to neutrino free streaming. Our analysis makes use of a recent model for the effect of neutrinos on the weakly non-linear matter power spectrum derived from accurate N-body simulations. We show that CFHTLS, combined with WMAP7 and a prior on the Hubble constant provides an upper limit of $\sum{m_ν}<0.29\,$eV and $N_{\rm{eff}} =4.17^{+1.62}_{-1.26}$ (2$\,σ$ confidence levels). If we omit smaller scales which may be affected by non-linearities, these constraints become $\sum{m_ν}<0.41\,$eV and $N_{\rm{eff}} =3.98^{+2.02}_{-1.20}$ (2$\,σ$ confidence levels). Finally we show that the addition of other large scale structures probes can further improve these constraints, demonstrating that high redshift large volumes surveys such as CFHTLS are complementary to other cosmological probes of the neutrino mass.

description: Following Laczkovich we consider the partially ordered set $\iB_1(\RR)$ of Baire class 1 functions endowed with the pointwise order, and investigate the order types of the linearly ordered subsets. Answering a question of Komjáth and Kunen we show (in $ZFC$) that special Aronszajn lines are embeddable into $\iB_1(\RR)$. We also show that under Martin's Axiom a linearly ordered set $\mathbb{L}$ with $|\mathbb{L}|<2^ω$ is embeddable into $\iB_1(\RR)$ iff $\mathbb{L}$ does not contain a copy of $ω_1$ or $ω_1^*$. We present a $ZFC$-example of a linear order of size $2^ω$ showing that this characterisation is not valid for orders of size continuum. These results are obtained using the notion of a compact-special tree; that is, a tree that is embeddable into the class of compact subsets of the reals partially ordered under reverse inclusion. We investigate how this notion is related to the well-known notion of an $\RR$-special tree and also to some other notions of specialness.

description: A key factor in the prevention and treatment of perinatal depression may be to improve overall micronutrient intake in pregnant women, which also appears to be fundamental to child cognitive and behavioural development. From the global literature, seven conceptual models helped to interpret the mechanism(s) by which micronutrients might influence mental health function. Further review of the literature revealed credible links between nutrient deficiency and mood for folate, vitamin B12, calcium, iron, selenium, zinc and omega-3 fatty acids. In the analysis of a longitudinal pregnancy cohort called the Alberta Pregnancy Outcomes and Nutrition study, women with lower depression scores had higher mean intakes of selenium (p = 0.0015) and omega-3s (p = 0.01), while women with higher depression scores were less likely to have been born in Canada (p = 0.01), more likely to have greater number of chronic conditions (p = 0.05) and stressful life events during pregnancy (p = 0.02), and lower prenatal and postnatal support (p = 0.0043 and p = 0.0001, respectively). Adjusting for covariates and nutrients associated with postpartum depression, women with high prenatal depression scores had increased odds of postpartum depressive symptoms (second and third trimester OR = 3.29, 95% CI = 1.55 - 7.01, p = 0.004 and OR = 4.26, 95 CI = 2.05 - 8.85, p < 0.0001, respectively), while prenatal supplemental selenium (per 10 µg, OR = 0.76, 95% CI = 0.74 - 0.78, p = 0.0019) and postnatal social support (OR = 0.87, 95% CI = 0.78 - 0.97, p = 0.0015) were protective. For child neurodevelopment, micronutrients are crucial to neuronal function and synaptic plasticity, and ultimately, brain health and mental function. A systematic review found perinatal intake of multi-micronutrients and n-3 fatty acids had some positive effect on child neurodevelopment, but the results were inconclusive, and more research was needed. Overall findings indicated multi-micronutrients may confer benefits to mental health in pregnant women, and to child behavioural and neurocognitive function.

description: We describe an array of spin-exchange relaxation free optical magnetometers designed for detection of fetal magnetocardiography (fMCG) signals. The individual magnetometers are configured with a small volume with intense optical pumping, surrounded by a large pump-free region. Spin-polarized atoms that diffuse out of the optical pumping region precess in the ambient magnetic field and are detected by a probe laser. Four such magnetometers, at the corners of a 7 cm square, are configured for gradiometry by feeding back the output of one magnetometer to a field coil to null uniform magnetic field noise at frequencies up to 200 Hz. Using this array, we present the first measurements of fMCG signals using an atomic magnetometer.
Perceptions and Understanding of Family Violence Among Japanese Canadians

description: This study explores and describes how Japanese Canadian participants in Edmonton and Calgary perceive and understand family violence. A qualitative descriptive methodology was utilized as the research method, and data was collected from ten Japanese Canadians through individual and focus group formats. Findings indicate that participants appeared to have a bounded view toward family violence. A bounded understanding of family violence included actions that were direct, intense, visible, and frequent. Participants indicated that Japanese culture influences participants’ perceptive on family violence. Language coveys culture and may limit perceptions; a strong patriarchal value places males at risk to abuse wives and children. This study also examines the barriers to reporting incidence of family violence and to access services. This study presents implications and direction for social work practice with Japanese heritage group and may also be applicable to wider social work practice inter-culturally.
Three-dimensional radiation flux source areas in urban areas
Creators: name: Roberts, Sarah Marie
Publisher: name: University of British Columbia
Year: 2010

description: Outdoor physical scale modeling is a potentially powerful compromise between the more common numerical and observational techniques to understand urban climates, because it incorporates the experimental control of physical and numerical modeling but is subject to the real complexities associated with natural environmental forcing. An outdoor physical model of simple concrete “buildings” was constructed to simulate an “urban” array in three different configurations. Observations of both facet surface temperatures and of radiation fluxes within and above the urban canopy layer investigate the impact of surface-sensor-sun relations on measured radiation flux source areas. Field measurements from the scale model were complemented by analyses using two numerical models. The combined results guide development of a protocol to guide the optimal siting of radiation sensors in measurement projects of the urban surface energy balance. The siting protocol considers both the influence of surface structure and orientation on radiation source areas and on the streamwise dimensions of the equivalent turbulent flux source area ‘seen’ by turbulence sensors. Observed thermal patterns from the scale model compare well with those at similar full-scale urban sites. Measurements of the spatial variation in radiation fluxes reveal that measurement heights above approximately 2.5 times the mean building height generate uniform flux density patterns. An agreement index used to quantify the strength of correspondence between what a sensor ‘sees’ of an urban surface and the actual surface morphology demonstrates that measurement locations near a street intersection give results closest to those sought to represent the local scale. Relations derived to describe the measurement height at which the radiation flux source area of a radiation sensor encompasses the source area of a turbulent flux sensor, reveal the common practice of co-locating tower-based radiation and turbulence flux sensors is often not sufficient to ensure their overlap. To match radiation flux source areas to the streamwise extent of turbulence flux source areas, it is recommended that radiation flux sensors be sited so as to contain the location of the maximum turbulent flux source weight. This suggests that radiation sensor(s) should be about two- to three times higher in elevation than the turbulence sensor(s).

description: Method: Patients with heart attack were identified in the Calgary Laboratory Services database as having a blood test with a critical value indicating heart attack. A second group of participants with no heart issues were identified in the same database and matched to the heart attack group by age and sex at a 1:4 ratio. All participants were mapped in a mapping program and individual level information about the density and distance to fast food outlets was collected. This geographic data was exported for statistical analysis. Results: If the density of fast food within 1000 meters is above average a participant is 1.226 times more likely to have a presumptive heart attack than participants with exposures less than average. Conclusions: More study is required to determine if this relationship is time dependent and whether this relationship is also affected by fast food around workplaces.

Platyrrhinus dorsalis

description: Platyrrhinus dorsalis (Thomas, 1900)
 Synonyms
 Vampyrops dorsalis Thomas, 1900:269.
Type locality: ‘‘ Paramba, [Imbabura,] N. Ecuador. Alt. 1,100 m.’’
 Platyrrhinus chocoensis Alberico and Velasco, 1991:238.
Type locality: Quebrada El Platinero, 12 km W Istmina (by road), Department of Chocó, Colombia.
 Distribution. Platyrrhinus dorsalis occurs at elevations from sea level to above 2,000 m from southern Panama southward into Colombia and along both slopes of the Andes in Ecuador.
 Diagnosis. Lowland populations assigned to chocoensis are medium-size bats (FA [forearm length] 46.9–50.7 mm; CIL [condyloincisive length] 24.3–26.6 mm; Velazco and Gardner [2009]: table 3) characterized by a pale brown dorsal coloration, brownish and bicolored ventral fur; wellmarked folds in the pinnae; fossa on the squamosal end of the zygomatic arch lateral to the glenoid fossa absent or almost imperceptible; stylar cusp on the lingual face of the M2 metacone absent;only the labial cingulid present on the second lower premolar; and stylid cusp between the metaconid and protoconid of the m2 usually absent. In contrast, mid to high elevation populations assigned to dorsalis are medium-size bats (FA 46.6–49.5 mm, CIL 24.1–26.3 mm; Velazco and Gardner [2009]: table 3) characterized by a dark brown dorsal coloration, brownish and tricolored ventral fur; poorly marked but distinguishable folds in the pinnae; deep fossa on the squamosal end of the zygomatic arch lateral to the glenoid fossa; stylar cusp on the lingual face of the M2 metacone present; both labial and lingual cingulids present on the second lower premolar; and stylid cusp between the metaconid and protoconid of the m2 present.
 Remarks. Linear morphometric analyses did not reveal secondary sexual variation among populations of chocoensis or dorsalis (Palacios-Mosquera et al. 2020). The PCA showed that populations of chocoensis and dorsalis form two clusters in morphospace (Palacios-Mosquera et al. 2020: fig. 2), with individuals of chocoensis being larger than dorsalis. Molecular analyses recovered specimens of chocoensis nested within a larger clade that included specimens only of dorsalis (Palacios-Mosquera et al. 2020).

description: We demonstrate, for the first time, an all-dielectric metamaterial resonator in the mid-wave infrared based on high-index tellurium cubic inclusions. Dielectric resonators are desirable compared to conventional metallo-dielectric metamaterials at optical frequencies as they are largely angular invariant, free of ohmic loss, and easily integrated into three-dimensional volumes. With these low-loss, isotropic elements, disruptive optical metamaterial designs, such as wide-angle lenses and cloaks, can be more easily realized.

description: Since the first publications of World University Rankings in 2003, rankings got established as a phenomenon of modern academia. The emergence of funding-based research schemes, the urge for accountability and the globalizing academic market in which universities must compete for resources and students generated an interest in tools to indicate quality and status of higher education. Rankings, in this sense, disperse necessary market information and function as a legitimization for quality, reputation and international outlook. Through the application of quality indicators and data weightings, rankings agencies set the standard for a different notion of quality and excellence. This means that although university rankings claim to evaluate research performance and quality of teaching, they test how responsive to auditing institutions are and how they match with rankings’ performance indicators. However, rankings have contradictory implications, because quality indicators that are criticized such as reputation and international outlook contribute to good rankings’ performances. The aim of this thesis is to investigate how these tensions are negotiated and to what extent university rankings influence higher education policy in the Netherlands. To evaluate this, I investigated practices of data submission, analysis and communication in Dutch academia. Beyond the framework of strategic rankings policies, policy officers fall back on different repertoires to give meaning to their approach to rankings related practices. To analyze these repertoires, I employed an ethnographic approach and conducted interviews with researchers and policy officers from Dutch research institutions. I subsequently contextualized this ethnographic data with data from the government, university websites, newspapers and institutional policy documents. Extending beyond the experiences of policy officers, researchers and students, this research is of interest to policymakers, higher education managers and politicians providing insights into the subject of rankings and the wider implications of rankings’ practices and excellence-driven policies in public research universities in the Netherlands.

description: Bacterial oxidoreductases play a key role in anaerobic respiration and represent a group of enzymes with complex maturation pathways. A group of specific chaperones, or redox enzyme maturation proteins (REMP), have been shown to interact tightly with the amino terminal signal peptide of oxidoreductase subunits. DmsD, the REMP associated with the oxidoreductase dimethyl sulfoxide (DMSO) reductase, has been putatively shown to interact with two general chaperones, DnaK and Trigger Factor (TF). Here, we begin to characterize the protein interactions between DnaK and TF and the DMSO reductase maturation system. DmsD was found not to associate with the ribosome for early access to its peptide substrate E. coli deficient in DnaK or TF grew more slowly when forced to respire DMSO, linking them to DMSO reductase maturation. While interactions could not be found between DnaK or TF and DmsD, both chaperones interacted with the signal peptide of DMSO reductase.
A Proposed Mechanism for Enhanced Titin-Based Force during Ca2+-activation

Year: 2017
Subjects: subject: Physiology

subject: Engineering--Biomedical

description: When an active skeletal muscle sarcomere is stretched, it generates more force after the stretch is completed when compared to a contraction at the same corresponding length. This mechanical property of skeletal muscle defies explanation by any conventional mechanism of contraction. Surmounting evidence indicates that the explanation for enhanced force following active stretch may be provided by the titin protein in the sarcomere, which becomes stiffer during Ca2+-activation. This thesis explores the mechanisms by which titin force is enhanced in actively stretched sarcomeres. Known to stiffen in the presence of Ca2+, the first study quantifies the contribution of Ca2+ to enhanced titin force, showing that an alternative mechanism accounts for the majority of titin force enhancement. The mechanism is further investigated using chemical inhibition of cross-bridges which shows that titin force enhancement is initiated with the development of contractile force. The next set of studies increase support for an interdependence of titin force enhancement and contractile force, showing that titin force enhancement is essentially eliminated and contractile force is decreased in sarcomeres with muscular dystrophy with myositis (mdm), a genetic mutation affecting the titin protein. The final study seeks to determine whether mechanical deficiencies in titin force enhancement are observed in a less reduced, single fiber preparation. Mutant fibers generated comparable contractile force and total force following active stretch beyond filament overlap as control fibers. Titin force enhancement was abolished in some mutant fibers and measured in other mutant fibers suggesting that the mdm mutation differentially affects fibers (and titin) in skeletal muscle. Passive force was increased in mutant fibers, showing that alternative structural components in a fiber can re-establish enhanced active stiffness in the absence of titin force enhancement. Collectively, the findings from this thesis show that titin-based force enhancement is an inherent property of skeletal muscle. The mechanism of titin force enhancement is crucial to sarcomere mechanics; as in its absence, sarcomeres generate less force and alternative structures to titin establish a comparable increase in active stiffness.

description: Background: Malnutrition is prevalent in patients receiving hemodialysis (HD). Compared to conventional HD (CHD), in-centre nocturnal hemodialysis (ICND) has shown improvements in patients’ dietary intake, body composition and mortality risk. Methods: We assessed the feasibility of some nutrition assessment tools (MIS, dietary intake, and anthropometric, functional and biochemical measurements) among 10 CHD and 9 ICND patients for a future study to investigate whether ICND is associated with an improvement in nutrition status compared to CHD. Results: Lean tissue mass was higher at baseline (p=0.007), handgrip strength was higher at 6 months (p=0.04) among ICND patients. Dietary intakes were non-significantly higher at both time points and phosphate binder dosage non-significantly declined in the ICND group. The ICND group had a high attrition rate (44%) over 6 months. Conclusion: These potentially clinically important findings merit further investigation with a more comprehensive study to determine whether ICND offers a nutritional advantage over CHD.

The observed energy levels and the electromagnetic transition probabilities of the nearly degenerate chiral dipole bands in this isotope are well reproduced by the present model. This demonstrates the broad applicability of the TPSM approach, based on a schematic interaction and angular-momentum projection technique, to explain a variety of low- and high-spin phenomena in triaxial rotating nuclei.

Cultureless rights : the cultural framework for indigenous rights in the Canadian and Australian judiciaries
Creators: name: Paterson, Travis
Publisher: name: University of British Columbia
Year: 2010

description: The relationship between the common law of Canada and Australia and Indigenous peoples has been one plagued by the logic of dispossession and domination. For over 200 years colonial courts effectively ignored Indigenous claims to the continued existence of their rights to traditional lands and self-government. In their respective attempts to address their own colonial histories, the Canadian and Australian courts have both begun to recognize the rights and title of Indigenous peoples to their traditional land-bases. Initially this gesture appeared to promise greater rights and freedoms for Indigenous peoples, including entitlement to self-government and the right to manage and benefit from traditional lands without the need for external authorization. Unfortunately, however, in a number of recent decisions the progress demonstrated by the courts in earlier cases has stalled, even reversed. This thesis will demonstrate that where the Canadian and Australian courts have recognized Indigenous rights and title they have done so by applying a culturalist framework. I argue that this culturalist framework has served to arbitrarily circumscribe the scope of Indigenous rights to a narrowly conceived bundle of “cultural” rights which privileges the sovereignty and title of the state over that of Indigenous peoples. Because of their reliance on a cultural approach to the interpretation of Aboriginal rights, common law courts have proven to be severely restricted in their capacity to recognize rights that would translate into greater freedom and equality for Indigenous peoples. In light of this, I conclude that although the law can be a powerful tool for furthering Indigenous rights, the courts cannot be the primary source of greater freedom and equality. Because of their inherently conservative nature courts often follow precedent and generally rely on norms and rules already accepted in the greater society. For this reason, although they can protect and encourage certain rights movements, the courts must radically alter their conceptual framework before significant changes and improvements can be made to Indigenous title jurisprudence.

description: Background: The Registered Nurse role requires competency of the affective domain; demonstrated by the ability to listen, respond to interactions, demonstrate appropriate attitudes, and display commitment. There is a paucity of research exploring the evaluation of student nurses’ competency in this domain. Aim: To explore how clinical nursing instructors evaluate students’ affective competency. Methods: 12 instructors from a large urban university were interviewed and data was analyzed using qualitative interpretive description methodology. Findings: Affective competency is highly valued in nursing, lacks consensus in definition, exists in a hidden curriculum, and is assessed through observation, dialogue and reflective writing. Explicit connections between assessment and evaluation are lacking. Discussion: Clinical nurse instructors are gatekeepers to the nursing profession. Affective competency is observed rather than evaluated, and an ontological turn in nurse education might change the motivation for affective evaluation; away from competency and toward being a nurse.

description: Edward Said’s work, particularly Orientalism (1978), has fallen out of fashion after a number of criticisms aimed at its representation of history, its perceived reliance on (and potential entrenchment of) stark binaries, and its lack of attention to resistant cultural productions, as well as a more general reassessment of the utility and value of postcolonial studies. Yet never has his work seemed more urgent or suited to the cultural moment. Political and cultural discourse after 9/11 spawned a renewal of Orientalist depictions of Muslim societies and, in particular, women. This dissertation argues that postcolonial novelists have engaged with these narratives in a variety of ways: feeding into established narratives and fears and lending them additional credence as “cultural informants”; exploding false binaries and spotlighting the link between colonialism and globalization; and complicating the pervasive representation of 9/11 as a contained narrative. It finds examples of these approaches in Khaled Hosseini’s A Thousand Splendid Suns (2007), Kiran Desai’s The Inheritance of Loss (2006), and Kamila Shamsie’s Burnt Shadows (2009) and suggests that each novel engages differently with the post-9/11 figure of the Muslim Other and/or the language of Orientalism that continues to circulate. This dissertation contends that the global, political, and cultural events of the last fifteen years call for a regeneration of postcolonial studies and a reinvestment in Said’s work. Orientalism did not end with the dissolution of the age of Empire, and it is incumbent upon postcolonial scholars to draw attention to and dismantle it in its many contemporary forms. This dissertation aims to participate in this undertaking.

description: Dyadic data are common in the social and behavioral sciences, in which members of dyads are correlated due to the interdependence structure within dyads. The analysis of longitudinal dyadic data becomes complex when nonignorable dropouts occur. We propose a fully Bayesian selection-model-based approach to analyze longitudinal dyadic data with nonignorable dropouts. We model repeated measures on subjects by a transition model and account for within-dyad correlations by random effects. In the model, we allow subject's outcome to depend on his/her own characteristics and measure history, as well as those of the other member in the dyad. We further account for the nonignorable missing data mechanism using a selection model in which the probability of dropout depends on the missing outcome. We propose a Gibbs sampler algorithm to fit the model. Simulation studies show that the proposed method effectively addresses the problem of nonignorable dropouts. We illustrate our methodology using a longitudinal breast cancer study.

description: In this thesis we design and implement three approaches to provide efficient Secure Two- Party Computation (2PC) protocols that are secure in presence of malicious adversaries. The field of secure two-party computation enables two mutually distrusting parties, each with their own private input, to run a computation of an arbitrary program. At the end of the computation, nothing about their private input is leaked except for what can be learned from the output of the computation. The seminal work of Yao in 1986 provided the first proof that such a computation is feasible using the so called garbled circuits and given an Oblivious Transfer protocol. In this thesis, we follow Yao’s garbled circuit approach and focus on efficient protocols that are secure against malicious adversaries. We examine three different categories of optimization. In each category, we present a 2PC protocol, prove its security, and implement it as a proof of concept to demonstrate its running time in practice. Non-interactive Secure Computation: In this category, we offer the first implementation of a malicious 2PC protocol that reduces the required rounds of interaction between the two parties to only two rounds (i.e., each party sends only one message to the other party). Mixed Secure Two-Party Computation: In the second category we target big and complex programs and break them into subprograms. Then, we compute each subprogram using the most efficient 2PC protocol that is suitable for it. Finally, we securely connect these subprograms together. The goal is to reduce the overhead of the garbled circuits significantly, which results in a more efficient overall 2PC protocol for programs with specific properties. Secure Computation for Random Access Machine Programs: In the third category, we target programs that require random access to the memory (as opposed to a sequential access). We present the first efficient maliciously-secure protocol for computing such programs.

 Synonyms
 Vampyrops umbratus Lyon, 1902:151.
type locality:" San Miguel,̎ La Guajira, Colombia.
 Vampyrops oratus Thomas, 1914:411.
type locality: "Galifari, Sierra del Avila, [Distrito Federal] N. Venezuela. Alt. 6500’ ̎ [emend to " Galipán (10° 33’ N, - 66° 54’ W, 1,980 m), Cerro Ávila, 5.7 km NE Caracas, Vargas, Venezuela ̎].
 Vampyrops nigellus Gardner and Carter, 1972:1.
type locality: "Huanhuachayo (12° 44’ S, - 73° 47’ W), about 1,660 m, Departamento de Ayacucho, Peru.̎
 Distribution. Platyrrhinus umbratus occurs at elevations from 400 m to above 3,150 m in the Andean and Caribbean Mountain systems of Venezuela and Colombia, and along the Andes in Ecuador, Peru, and Bolivia.
 Diagnosis. Southern and some northern populations (nigellus) of the species are medium-size bats (FA 40.6– 48.0 mm, CIL 21.9–25.2 mm; Velazco and Gardner [2009]: table 4) characterized by a tricolored ventral fur; densely haired fringe on the edge of the uropatagium; postorbital process absent or poorly developed; M1 protocone moderately developed; stylar cusp on the lingual face of the M2 metacone absent; m2 hypoconid absent; and stylid cusp between the metaconid and protoconid of the m2 present. In contrast, northern populations (umbratus) of the species are medium-size bats (FA 42.0–47.8 mm, CIL 23.4–25.1 mm; Velazco and Gardner [2009]: table 4) characterized by a bicolored ventral fur; margin of the uropatagium usually hairy, sometimes sparsely haired; postorbital process moderately developed; M1 protocone well developed; stylar cusp on the lingual face of the M2 metacone present; m2 hypoconid present; and stylid cusp between the metaconid and protoconid of the m2 absent.
 Remarks. Analyses of linear measurements of nigellus populations did not reveal secondary sexual variation among populations (Velazco and Solari 2003). Linear morphometric analyses recovered a high overlap between specimens of nigellus and umbratus, indicating similarities in size and shape (Velazco et al. 2018). Molecular analyses recovered specimens of nigellus and umbratus clustering together, forming non monophyletic groups (Velazco et al. 2018). Ecological niche modeling analyses found that the potential distributions of umbratus and nigellus in the geographic space were highly similar, suggesting that both groups exhibit broadly overlapping climatic niches with no ecological differentiation (Velazco et al. 2018).

description: Accessing HPC storage remotely can be cumbersome and involve using out-of-band tools (i.e. NFS, SCP, or SSHFS on Windows or SMB on Linux). We have begun to provide users access to our HPC storage using a tool that enables a familiar interface and behavior - like OneDrive or Dropbox - and unifies access to university-wide storage pools. We will walk through the software, configuration, lessons learned, and next steps in offering this service to our researchers. We are also exploring the use of built-in file tagging and other internal automation to provide a sensitive data workflow for HIPAA-aligned data security. Efficacy and lessons learned from this approach will be discussed.

description: The spiral magnetic order in cubic MnSi-type crystals is considered using the model of classical Heisenberg ferromagnetics with an extra interaction of the Dzyaloshinskii-Moriya (DM) type between neighboring atoms. It is found how the wave vector of magnetic helices depends on DM vector. The wave number k determines both the sign and strength of global spiraling whereas locally, within a unit cell, the helical order can be strongly frustrated so that the twist angles between neighboring ferromagnetic layers may be even of different signs. Conical deformations of helices caused by an arbitrary directed external magnetic field is also considered within the same model. The critical field of helix unwinding is found and it is shown that even in the unwound state there remains a residual periodic splay of magnetic moments which can be measured by diffraction methods. It is also demonstrated how the usually used continuous picture of moment distribution can be obtained from the discrete one in a coarse grain approximation.
