description: There is considerable controversy concerning the role of cadaveric dissection in teaching gross anatomy and the potential of using 3D computer-generated images to substitute for actual laboratory dissections. There are currently few high-quality 3D virtual models of anatomy available to evaluate the utility of computer-generated images. Existing 3D models are frequently of structures that are easily examined in three dimensions by removal from the cadaver, i.e., the heart, skull, and brain. We have focused on developing a 3D model of the pelvis, a region that is conceptually difficult and relatively inaccessible for student dissection. We feel students will benefit tremendously from 3D views of the pelvic anatomy. We generated 3D models of the male pelvic anatomy from hand-segmented color Visible Human Male cryosection data, reconstructed and visualized by Columbia University's in-house 3D Vesalius Visualizer.1 These 3D models depict the anatomy of the region in a realistic true-to-life color and texture. They can be used to create 3D anatomical scenes, with arbitrary complexity, where the component anatomical structures are displayed in correct 3D anatomical relationships. Moreover, a sequence of 3D scenes can be defined to simulate actual dissection. Structures can be added in a layered sequence from the bony framework to build from the "inside-out" or disassembled much like a true laboratory dissection from the "outside-in." These 3D reconstructed anatomical models can provide views of the structures from new perspectives and have the potential to improve understanding of the anatomical relationships of the pelvic region (http://www.cellbiology.lsuhsc.edu/People/Faculty/Venuti_Figures/movie_index.html).
Nlakapmux grandmothers’ traditional teachings and learnings
Creators: name: Anderson, Beatrice Marie
Publisher: name: University of British Columbia
Year: 2011

description: Nchwa’ squest. My name is Beatrice Tiila Marie Anderson. I am Nlakapmux, a social worker, educator, mother, wife, Grandmother, and great Grandmother. Not all learning in Indigenous communities is attained through formal institutional settings. Much of our important learning comes from Indigenous Knowledge (IK) passed on through family and social contexts. This research examines, documents, and contributes to knowledge about how generations of Indigenous Nlakapmux Grandmothers from the Interior of British Columbia carried out their responsibilities to transmit Nlakapmux educational and socio-cultural knowledge to their family and community members. Grandmothers are a critical part of the family’s social learning environment. This knowledge is important to understand because traditional family pedagogies were and continue to be at the heart of how Nlakapmux children learn and how Nlakapmux knowledge and values are transmitted and sustained. The process of colonization lessened this important approach to Indigenous intergenerational learning. A Nlakapmux Grandmother’s Methodology was developed that includes a Spilahem story of my life history; an analysis of historical and contemporary literature about the Nlakapmux people; and interviews and circle talks with 11 Nlakapmux Grandmothers. The Nlakapmuxcin Indigenous language, wholistic Plains Medicine Wheel, and metaphor of the Nlakapmux cedar root basket making were used to analyze and make meaning of the Grandmothers’ stories. The findings highlight eight Nlakapmux principles for teaching and learning that form the basis of a Nlakapmux Developing Wisdom Theory. They include: (1) Takemshooknooqua, Knowing we are connected: land, animals, plants and people; (2) ChaaChawoowh, Celebrating people and land joyously; (3) Huckpestes, Developing lifelong learning and wisdom; (4) Huztowaahh, Giving lovingly to family and community; (5) Choownensh, Succeeding in endeavours; (6) Choowaachoots, Utilizing Nlakapmux vision-seeking methods; (7) Nmeenlth coynchoots, Incorporating Nlakapmux knowledge; and (8) Peteenushem, Reflecting on learning and relearning lifelong lessons. These findings and the Nlakapmux Developing Wisdom Theory have implications for current and future child rearing practices, and family and community educational practices. This form of intergenerational family focused Indigenous knowledge is vital to the Nlakapmux people and needs to be consciously revitalized, transformed into current day pedagogy and practice, and transmitted to younger Nlakapmux generations.

description: Two lignans including a new one, five flavonoids and five coumarins were isolated from the whole plant of Viola philippica (synonymised as Viola yedoensis Makino). The new compound was structurally determined as (7R,8S,8′S) -3,3′-dimethoxy- 4,4′,9-trihydroxy- 7,9′-epoxy-8,8′-lignan 9-O-rutinoside by analysis of its NMR, MS and CD spectroscopic data. The known compounds were characterised by comparing their NMR and MS data with those reported. Among the known compounds, 5-hydroxy-4′-methoxyflavone-7-O- rutinoside, 6,7-di-O-β-D- glucopyranosylesculetin, and 7R,8S-dihydrodehydrodiconiferyl alcohol 4-O-β-D- glucopyranoside were isolated and identified from this genus for the first time. Of these compounds, 5-hydroxy-4′-methoxyflavone-7-O-rutinoside and (7R,8S,8′S) -3,3′-dimethoxy- 4,4′,9-trihydroxy- 7,9′-epoxy-8,8′-lignan 9-O-rutinoside were potently active against α-glucosidase, while the two dimeric coumarins, 5, 5′-bi (6, 7-dihydroxycoumarin) and 6,6′,7,7′-tetrahydroxy-5,8′-bicoumarin potently inhibited HCV protease.

description: Genuine multipartite entanglement of a quantum system can be partially destroyed by local decoherence. Is it possible to retrieve the entanglement to some extent by a single local operation? The answer to this question depends very much on the type of initial genuine entanglement. For initially pure W and cluster states and if the decoherence is given by generalized amplitude damping, the answer is shown to be positive. In this case, the entanglement retrieving is achieved just by redistributing the remained entanglement of the system.

Science--Study and teaching

description: The introduction of the Visible Human Project by Ackerman in 1995, described in the seminal paper in 1996, brought a promise to anatomists that these two frozen, milled, and digitized cadavers--the Visible Male and Female--would revolutionize anatomy teaching by providing the most complete and detailed anatomical images ever. This vision could be compared to the proverbial "man on the moon" program for medical education and has proven to be much more challenging than expected. Although the ramifications of this project are not of the same scale as the shock created five centuries ago by the Padua physician Andreas Vesalius when he challenged the ancient Greek physician Galen's description of the human body, the original interest created by the availability of the Visible Human data was enormous.

description: Recent progress on micro- and nanometer scale manipulation has opened the possibility to probe systems small enough that thermal fluctuations of energy and coordinate variables can be significant compared with their mean behavior. We present an experimental study of nonequilibrium thermodynamics in a classical two-state system, namely a metallic single-electron box. We have measured with high statistical accuracy the distribution of dissipated energy as single electrons are transferred between the box electrodes. The obtained distributions obey Jarzynski and Crooks fluctuation relations. A comprehensive microscopic theory exists for the system, enabling the experimental distributions to be reproduced without fitting parameters.

description: Remote Sensing and GIS analyses were embedded to monitor interactions and relationships between land use and land cover changes in the regional ecological space of Gobi-Altai province (Western part of Mongolia). In the last 76 years, Mongolia has experienced a combination of societal and governance system changes in transitioning from the feudal system to socialism and then from the socialist system with centrally planned economy to market. Each of these resulted in changes natural resources use throughout the country. Using GIS processing of data such as climate data (precipitation, air temperature) and vegetation, socio-economic data (livestock numbers, population density) were analyzed. We focused on developing a modeling approach for monitoring land degradation using GIS and Remote Sensing tools by merging climate and quantitative socio-economic data. The Modified Soil Adjusted Vegetation Index (MSAVI) from SPOT/VEGETATION was used to define vegetation cover change for the period from 2000 to 2013. GIS conditional functions were applied for mapping and analyzing climate and socio-economic driving factors, both of which affect land degradation. Conditional functions such as MAP-Algebra from ArcGIS were developed using ground truth data and data from National Administrative Department of Statistics. Remote sensing data were useful diagnostic tools for providing gross impressions on broad-scale spatial heterogeneity, to assist in land degradation monitoring. This paper defines that study area is affected by land degradation caused by climate and socio economic impacts.

description: Objective: Up to 25% of patients experience subtle declines in post-operative neurocognitive function following, otherwise uncomplicated, carotid endarterectomy (CEA). We sought to determine if post-CEA neurocognitive deficits are associated with cerebral blood flow (CBF) abnormalities on post-operative MR perfusion brain scans. Methods: We enrolled 22 CEA patients to undergo a battery of neuropsychometric tests pre-operatively and on post-operative day 1 (POD 1). Neurocognitive dysfunction was defined as a two standard deviation decline in performance in comparison to a similarly aged control group of lumbar laminectomy patients. All patients received MR perfusion brain scans on POD 1 that were analysed for asymmetries in CBF distribution. One patient experienced a transient ischemic attack within 24 hours before the procedure and was excluded from our analysis. Results: Twenty-nine percent of CEA patients demonstrated neurocognitive dysfunction on POD 1. One hundred percent of those patients with cognitive deficits demonstrated CBF asymmetry, in contrast to only 27% of those patients without cognitive impairment. Post-CEA cognitive dysfunction was significantly associated with CBF abnormalities (RR=3.75, 95% CI: 1.62-8.67, p=0.004). Conclusion: Post-CEA neurocognitive dysfunction is significantly associated with post-operative CBF asymmetry. These results support the hypothesis that post-CEA cognitive impairment is caused by cerebral hemodynamic changes. Further work exploring the relationship between CBF and post-CEA cognitive dysfunction is needed.

Effects of Fermion Flavor on Exciton Condensation in Double Layer Systems

description: We use fermionic path integral quantum Monte Carlo to study the effects of fermion flavor on the physical properties of dipolar exciton condensates in double layer systems. We find that by including spin in the system weakens the effective interlayer interaction strength, yet this has very little effect on the Kosterlitz-Thouless transition temperature. We further find that, to obtain the correct description of screening, it is necessary to account for correlation in both the interlayer and intralayer interactions. We show that while the excitonic binding cannot completely surpress screening by additional fermion flavors, their screening effectiveness is reduced leading to a much higher transition temperatures than predicted with large-N analysis.

description: We study holomorphic spheres in certain symplectic cobordisms and derive information about periodic Reeb orbits in the concave end of these cobordisms from the non-compactness of the relevant moduli spaces. We use this to confirm the strong Weinstein conjecture (predicting the existence of null-homologous Reeb links) for various higher-dimensional contact manifolds, including contact type hypersurfaces in subcritical Stein manifolds and in some cotangent bundles. The quantitative character of this result leads to the definition of a symplectic capacity.

description: Wells in grasslands are usually accompanied with increased traffic by humans and livestock. The purpose of this study was to detect whether plant community structure differs in spatial arrangement with different grazing gradients in the desert steppe of Mongolia. We found poor correlation between total coverage and distance-to-well in big-shrub and shrub-limited sites but strong correlation in the small-shrub site. Dominance of palatable plants along the transect appeared in the big-shrub site but that of palatable, grazing avoider and grazing tolerant plants appeared in other two sites. The results show that these communities might respond differently to grazing pressure. Livestock trampling was limited to near the well and then grazing might be effective far from the well, because all sites showed dominance of palatable herbaceous plants. Sub-dominance of Eurotia ceratoides appeared nearest to the well and followed Caragana spp. sub-dominance. Ajania spp. sub-dominance appeared more away than E. ceratoides and Caragana spp. Dominance of palatable herbaceous plants appeared near the well, compared with that of shrubs. In all sites, palatable herbaceous plant community was replaced by grazing tolerant plant community near the well and shrubs disappeared. This indicates that succession after grazing might be faster in herbaceous plant community than shrub one.
Comparative Analysis of Cost and Time Aspects for the Use of Ulin Timber Deck and Andesite Materials usage as a Jogging Track Surface (Case Study: Hotel Aruss Semarang

description: Hotel property developers began to develop a hotel concept equipped with various supporting facilities including a jogging track. The jogging track area in the case study raised, namely the Aruss Semarang Hotel project, is planned to use ironwood decking cover material. Ironwood was chosen because it has strong and resistant characteristics, but is relatively expensive. Therefore, it is proposed to replace the ironwood decking material with burnt andesite. The burnt andesite material has the characteristic of being resistant to weather changes because it is formed from the freezing process of volcanic lava and has a surface that tends to be rough so it is suitable for use on pedestrian surfaces. In addition, the price of andesite material is relatively more affordable than ironwood, it is hoped that this alternative can save the implementation budget. To prove, an identification stage is carried out that presents a comparison of the cost and duration of the two materials. Cost identification is carried out using the direct cost method which is calculated based on the 2022 SNI AHS using the Semarang city wage &material price in 2021. The analysis of the duration of implementation will use the time study method, by calculating the capacity of labor productivity through the worker coefficient index in the AHS SNI. Through this series of identifications, the results of the analysis of the cost of surface jogging track work using alternative materials in the form of burnt andesite were cheaper at IDR 307,031,041.00 (73.91%) compared to ironwood material. Meanwhile, through duration analysis, it is known that the implementation time of burnt andesite material only takes 13 days while ironwood material takes 36 days, or 23 days faster.

description: We present a case of a 72-year-old female patient with a history of degenerative hip joint disease for whom a custom-made prosthesis—an acetabulum cage—was designed. With the growing number of total hip arthroplasty (THA) operations and the rapid development of technology, biology, and tissue bioengineering, there is a market to develop new artificial hip joints. The quality of the custom made prosthesis depends on the quality of segmentation to delineate accurately patient’s anatomy. The error of segmentation may propagate to the overall error of the final prosthesis. We evaluate an in-house segmentation method, that was used in the design of the custom made prosthesis, and a commercial segmentation method, using qualitative and quantitative approaches.

description: This article describes two case studies: one is from a graduate course in social work practice evaluation taught by the second author; the other is from an undergraduate political science course in media and politics taught by the first author. These cases describe the way blogs, created by students and the professors, facilitate communications within the class, reduce paperwork for the professors, and let students practice their 'public voices.' While the cases are specific to two courses-Masters-level social work and undergraduate political science-the concepts are easily transferred to others. The article begins with a history and literature review of blogs used pedagogically; next, the reader is walked through the creation of a blog using currently popular online tools; the next two sections are devoted to the two cases; and the final section attempts to draw some generalizations about using blogs in the classroom.

description: We report DC magnetization, detailed systematic linear and nonlinear AC magnetic susceptibility and transport for a single phase RuSr2Eu1.4Ce0.6Cu2O10-δ (EuRu-1222) magneto-superconductor. The studied sample is synthesized through standard solid state reaction route, which is crystallized in single phase tetragonal structure with space group I4/mmm. DC magnetic susceptibility measurements revealed that the studied EuRu-1222 is a magneto-superconductor with Ru spins ordering at around 110 K and superconductivity in the Cu-O2 planes below \approx 30 K. Temperature dependence of AC susceptibility with different frequency and amplitude variations confirms spin-glass behavior with cluster ferromagnetism of the system. Change in the cusp position with frequency follows the Vogel-Fulcher law, which is commonly accepted feature for a spin-glass (SG) system with ferromagnetic clusters. The third harmonic of AC susceptibility (\c{hi}3) shows that the system undergoes a spin glass transition below 80 K. Superconducting transition temperature (Tc) onset and ρ = 0 are seen at around 30 and 18 K without any applied field and the same decreases to 10 and 2 K under 130 kOe applied field. Also low fields isothermal (MH) suggests that ferromagnetic clusters are embedded in spin-glass (SG) matrix. The magnetization vs. applied field (MH) loops exhibited ferromagnetic (FM) like behavior with rather small coercive fields. Detailed AC magnetic susceptibility measurements are carried out to unearth the short range magnetic correlations. These results support the spin-glass (SG) formation followed by ferromagnetic clustering effects at low temperatures. Our detailed magnetization and magneto transport results will undoubtedly contribute to current understanding of the complex magnetism of the EuRu-1222 system.

description: It has been shown that solutions of a number of many-body problems out of equilibrium can be expressed in terms of Toeplitz determinants with Fisher-Hartwig (FH) singularities. In the present paper, such Toeplitz determinants are studied numerically. Results of our numerical calculations fully agree with the FH conjecture in an extended form that includes a summation over all FH representations (corresponding to different branches of the logarithms). As specific applications, we consider problems of Fermi edge singularity and tunneling spectroscopy of Luttinger liquid with multiple-step energy distribution functions, including the case of population inversion. In the energy representation, a sum over FH branches produces power-law singularities at multiple edges.

description: The importance of considering the volumes to analyze stock prices movements can be considered as a well-accepted practice in the financial area. However, when we look at the scientific production in this field, we still cannot find a unified model that includes volume and price variations for stock assessment purposes. In this paper we present a computer model that could fulfill this gap, proposing a new index to evaluate stock prices based on their historical prices and volumes traded. Besides the model can be considered mathematically very simple, it was able to improve significantly the performance of agents operating with real financial data. Based on the results obtained, and also on the very intuitive logic of our model, we believe that the index proposed here can be very useful to help investors on the activity of determining ideal price ranges for buying and selling stocks in the financial market.

description: We develop a multi-scale high-fidelity biomechanical and physiologically based modeling tools for trauma (ballistic/impact and blast) injury to brain, lung and spinal cord for resuscitation, treatment planning and design of personnel protection. Several approaches have been used to study blast and ballistic/impact injuries. Dummy containing pressure sensors and synthetic phantoms of human organs have been used to study bomb blast and car crashes. Large animals like pigs also have been equipped with pressure sensors exposed to blast waves. But these methods do not provide anatomically and physiologically, full optimization of body protection design and require animal sacrifice. Anatomy and medical image-based high-fidelity computational modeling can be used to analyze injury mechanisms and to optimize the design of body protection. This paper presents novel approach of coupled computational fluid dynamics and computational structures dynamics to simulate fluid (air, cerebrospinal fluid)–solid (cranium, brain tissue) interaction during ballistic/blast impact. We propose a trauma injury simulation pipeline concept staring from anatomy and medical image-based high-fidelity 3D geometric modeling, extraction of tissue morphology, generation of computational grids, multi-scale biomechanical and physiological simulations, and data visualization.

description: We construct a manifestly N=3 supersymmetric low-energy effective action of N=3 super Yang-Mills theory. The effective action is written in the N=3 harmonic superspace and respects the full N=3 superconformal symmetry. On mass shell this action is responsible for the four-derivative terms in the N=4 SYM effective action, such as F^4/X^4 and its supersymmetric completions, while off shell it involves also higher-derivative terms. For constant Maxwell and scalar fields its bosonic part coincides, up to the F^6/X^8 order, with the bosonic part of the D3 brane action in the AdS_5 x S^5 background. We also argue that in the sector of scalar fields it involves the correctly normalized Wess-Zumino term with the implicit SU(3) symmetry.

description: Rationale and Objectives: Perfusion-weighted computed tomography (CTP) is a relatively recent innovation that estimates a value for cerebral blood flow (CBF) using a series of axial head CT images tracking the time course of a signal from an intravenous contrast bolus. Materials and Methods: CTP images were obtained using a standard imaging protocol and were analyzed using commercially available software. A novel computer-based method was used for objective quantification of side-to-side asymmetries of CBF values calculated from CTP images. Results: Our method corrects for the inherent variability of the CTP methodology seen in the subarachnoid hemorrhage (SAH) patient population to potentially aid in the diagnosis of cerebral vasospasm (CVS). This method analyzes and quantifies side-to-side asymmetry of CBF and presents relative differences in a construct termed a Relative Difference Map (RDM). To further automate this process, we have developed a unique methodology that enables a computer to delineate vascular territories within a brain image, regardless of the size and shape of the brain. Conclusions: While both the quantification of image symmetry using RDMs and the automated assignment of vascular territories were initially designed for the analysis of CTP images, it is likely that they will be useful in a variety of applications.

Remodeling of the collecting duct with urinary tract obstruction

description: Urinary tract obstruction is a major cause of morbidity and mortality worldwide. Obstruction occurs in both the fetus and adult, can lead to impaired renal development, substantial renal injury, dysplasia, or progressive fibrosis of the kidney. Though different in outcome, fetal and adult obstruction both impair normal kidney function and promote the onset of chronic kidney disease. While a substantial amount of research has identified key features in the pathogenesis of obstruction, our understanding of the early events in the progression of obstructive injury is incomplete. In this thesis, I have used several experimental models to investigate the role of medullary and collecting duct injury following urinary tract obstruction. Research using these models has provided many key findings. First, I have established the previously unreported ontogeny of the collecting duct in the human fetal kidney. Second, I have defined the impact of urinary tract obstruction on the collecting duct and linked it to collecting duct injury. Third, I have characterized the response of the collecting duct and associated renal interstitium to obstruction, and identified cellular dedifferentiation and phenotypic transition as common outcomes of collecting duct injury. Last, I have characterized the expression, localization and protein-complex formation of TRPV4, and highlighted a mechanism for TRPV4 in the transduction of physical injury into a collecting duct epithelial response. Through investigation of clinical cases of fetal urinary tract obstruction and experimentation using 2 models of fetal and adult obstruction, I have demonstrated that collecting duct epithelial injury and remodeling is a common and conserved feature of obstructive injury and I have described a role for TRPV4 in the mechanosensation and transduction of the physical stimuli caused by obstructive injury. I believe TRPV4-mediated signal transduction, in part, provides a unifying mechanism for the induction of a repair and fibrosis during both fetal and postnatal urinary tract obstruction.

description: The concept of classifying any area into ecological sites, according to that area's productivity, based on varying soil, climatic and hydrological conditions, and its capacity to endure different intensities of use and to recover from degradation, and of using this classification as a basis of rational use of natural resources is more and more recognized internationally. Since 2009, the Green Gold Project funded by the Swiss Agency for Development and Cooperation (SDC) has been exploring opportunities to develop the ecological site description (ESD) concept for Mongolian rangelands and use it as an essential tool of rangeland management. Based on soil, vegetation and geomorphological data collected from approximately 500 points representing nationwide environmental zones, we developed the ESD concept for the Mongolian context. According to this concept Mongolian rangelands are divided into some 20 zones, representing distinct ecological potentials. Based on these plot data and state and transition models a preliminary conclusion is made that over 65 percent of Mongolian rangeland has, with varying degrees, altered from its reference state, and 80 percent of this area has potential to recover through changes in rangeland management. The main objective of this research was to identify, for each environmental zone, the main factors that determine rangeland ecological potential, to develop the ESD concept and to test the possibility of using it in rangeland management. The novelty of this study, as well as its scientific and practical significance, lie in development and testing of a more detailed classification based on ecological potential within Mongolian ecological zones and geo botanical regions. This approach is significant because the classification may be used as an essential tool for rangeland use planning, implementation and monitoring, as well as for regulating rangeland use agreements.
