Characterization of persistent multipath components in indoor and outdoor environment at 30 GHz
Creators: name: Liya, Badrun Naher
Publisher: name: University of British Columbia
Year: 2017

description: Millimeter-wave (mm-wave) frequency bands are under active consideration for use as short-range mobile broadband links in fifth generation (5G) cellular access networks. Although channel characteristics such as path loss, delay spread and fading distributions have been extensively studied for mm-wave channels, the study of the time-varying nature of the channel is still in its early stages. In this work, we studied the lifetime of multipath components of the mm-wave channel, usually referred to as persistence. An important time-varying characteristic of the mm-wave channel, persistence may affect the capacity, and beam training and beam tracking process of mm-wave systems. We developed a 30-GHz vector-network-analyzer-based channel sounder suitable for characterizing multipath persistence and verified its performance through a three-stage verification procedure; time and frequency domain verifications, two-ray verification, and measurements conducted using the National Institute of Standards and Technology (NIST) mm-wave channel sounder verification artifact. The primary goal of this work was to characterize multipath persistence based on measurements conducted at 30 GHz in indoor and outdoor urban microcell environments. Through analysis of our measurement data, we confirmed that the log-logistic distribution provides an accurate description of persistence and showed how the physical attributes of the channel influence the parameters of the distribution. We also verified that a weak correlation exists between average received power and length of the persistent path. We further showed that the rate of angular change of a multipath component throughout its lifetime follows a Laplace distribution and that the angular rate depends on the distance of reflectors from the transmitter-receiver path. We used these results to propose a simulation model that can be used to make simple ray tracing simulations more realistic and to assess the effect of persistence and variations in the angular rate on the capacity, and beam training and tracking process of mm-wave systems.

description: Infertility secondary to chemotherapy, myeloablative conditioning regimens prior to stem cell transplantation, radiation therapy, and/or surgery is an important cause of morbidity and psychosocial distress among pediatric cancer patients. Known options exist for fertility preservation; however, knowledge among providers varies. We conducted a pilot study with an educational intervention over one-hour for hematology-oncology faculty, fellows, and advanced practice providers. Participants completed pre-/post-test assessment on fertility preservation knowledge. Participants’ pretest mean (SD) score was 53% (17%), which significantly increased to 72% (11%) in the post-test (p = 0.0004). We demonstrated that a fertility education intervention could improve knowledge regarding infertility risk assessment and fertility preservation options.

description: Time domain reflectometry, a technique originally used in diagnosing cable faults, can also locate where a cable is being touched. In this paper, we explore how to extend time domain reflectometry in order to touch-enable thin, modular, and deformable surfaces and devices. We demonstrate how to use this approach to make smart clothing and to rapid prototype touch-sensitive objects of arbitrary shape. To accomplish this, we extend time domain reflectometry in three ways: (1) Thin: We demonstrate how to run time domain reflectometry on a single wire. This allows us to touch-enable thin metal objects, such as guitar strings. (2) Modularity: We present a two-pin connector system that allows users to daisy chain touch-sensitive segments. We illustrate these enhancements with 13 prototypes and a series of performance measurements. (3) Deformability: We create deformable touch devices by mounting stretch-able wire patterns onto elastic tape and meshes. We present selected performance measurements.

description: Recombinant factor VIII and factor IX Fc fusion proteins (rFVIIIFc and rFIXFc) were developed with an extended half-life (EHL) to improve the management of people with hemophilia A (PwHA) and B (PwHB), respectively. This survey gathered physician-reported treatment decisions and physician views on outcomes in PwHA or PwHB who switched to rFVIIIFc or rFIXFc in the 12 months prior to study completion. Physicians (N = 37) considered bleeds, pharmacokinetic parameters, joint health and adherence the most important factors to assess both in routine care and when deciding to switch to an EHL therapy. In the 12 months prior to study completion, 37 physicians switched 113 PwHA to rFVIIIFc and 25 physicians switched 36 PwHB to rFIXFc. Most PwH (>90%) had moderate or severe hemophilia and many (>60%) switched within 6 months of the survey. The main reason for switching PwHA to rFVIIIFc was to allow fewer injections (49%), while the main reason for switching PwHB to rFIXFc was the product becoming available for use (36%). Overall, 96% of PwHA and 89% of PwHB who were switched remained on these EHL products at the time of survey. Mean total weekly dose, injection frequency and annualized bleeding rate were reported to have reduced following switching. This survey provides valuable insight into reasons for, and challenges to, the use of EHL products in clinical practice. Physicians perceived that switching to treatment with rFVIIIFc or rFIXFc can improve quality of life, treatment burden, disease control and adherence.

description: E-commerce in today's conditions has the highest dependence on network infrastructure of banking. However, when the possibility of communicating with the Banking network is not provided, business activities will suffer. This paper proposes a new approach of digital wallet based on mobile devices without the need to exchange physical money or communicate with banking network. A digital wallet is a software component that allows a user to make an electronic payment in cash (such as a credit card or a digital coin), and hides the low-level details of executing the payment protocol that is used to make the payment. The main features of proposed architecture are secure awareness, fault tolerance, and infrastructure-less protocol.

description: Stem/progenitor cells are promising candidates to treat diseased renal parenchyma. However, implanted stem/progenitor cells are exposed to a harmful atmosphere of degenerating parenchyma. To minimize hampering effects after an implantation investigations are in progress to administer these cells within an artificial polyester interstitum supporting survival. Learning from nature the renal stem/progenitor cell niche appears as a valuable model. At this site epithelial stem/progenitor cells within the collecting duct ampulla face mesenchymal stem/progenitor cells. Both cell types do not have close contact but are separated by a wide interstitium.
Characterizing the knowledge and attitudes towards sharks and the domestic use of shark meat and fins in Peru
Creators: name: De La Puente Jeri, Santiago
Publisher: name: University of British Columbia

description: Shark populations show evidence of declines at a global scale. Knowledge of the socio-economic consequences of changes in their abundance is limited. Furthermore, research on the status of peoples’ knowledge and attitudes towards sharks and how these affect their values, behaviours and actions is lagging behind the pursuit of biological and ecological concerns. Framed within Peru’s National Plan of Action for the Conservation and Management of Sharks, Rays and Chimeras, the present study sought to: (1) characterize coastal Peruvian’s general knowledge and attitudes towards sharks and shark meat consumption; (2) describe the domestic market and trade flows of shark commodities; (3) estimate the apparent consumption of shark meat and fins in Peru; and (4) reconstruct the catches required to maintain the estimated local levels of shark consumption. Using data from over 2000 surveys provided by OCEANA Peru, I determined that a limited proportion of the Peruvian coastal population was aware of sharks’ presence in the country’s waters, and of these, only a minor subset was capable of naming shark species found locally. Furthermore, Peruvians have very negative attitudes towards sharks, driven by fear and prevalent misconceptions regarding their feeding habits and behaviour, which are reinforced by mass media. Using public data, provided by various organizations within the Peruvian government, I determined that shark meat consumption in Peru is high and growing, although its contribution to national food security remains low. Nonetheless, most shark meat consumers are not aware that they are eating sharks due to deceptive advertising. Improvements on seafood traceability have only been observed on exports, as data associated with landings, local markets and imports remains highly aggregated. Moreover, official statistics severely underestimate the catches required to maintain the Peruvian supply (by 39%) and demand (by 85%) of shark products. These findings can be used to inform the design of communications campaigns and government policies seeking to: (i) improve people’s knowledge and attitudes towards sharks in Peru, (ii) increase seafood traceability, (iii) protect seafood consumers, and (iv) advance towards the incorporation of these dimensions in the quantitative evaluation of policy outcomes for achieving sustainable shark fisheries.

description: Suppose a finite group acts on a scheme $X$ and a finite-dimensional Lie algebra $\mathfrak{g}$. The associated equivariant map algebra is the Lie algebra of equivariant regular maps from $X$ to $\mathfrak{g}$. The irreducible finite-dimensional representations of these algebras were classified in previous work with P. Senesi, where it was shown that they are all tensor products of evaluation representations and one-dimensional representations. In the current paper, we describe the extensions between irreducible finite-dimensional representations of an equivariant map algebra in the case that $X$ is an affine scheme of finite type and $\mathfrak{g}$ is reductive. This allows us to also describe explicitly the blocks of the category of finite-dimensional representations in terms of spectral characters, whose definition we extend to this general setting. Applying our results to the case of generalized current algebras (the case where the group acting is trivial), we recover known results but with very different proofs. For (twisted) loop algebras, we recover known results on block decompositions (again with very different proofs) and new explicit formulas for extensions. Finally, specializing our results to the case of (twisted) multiloop algebras and generalized Onsager algebras yields previously unknown results on both extensions and block decompositions.

description: Global treatment guidelines recommend treatment with oral anticoagulants (OACs) for patients with non-valvular atrial fibrillation (NVAF) and an elevated stroke risk. However, not all patients with NVAF and an elevated stroke risk receive guideline-recommended therapy. A literature review and synthesis of observational studies were undertaken to identify the body of evidence on untreated and undertreated NVAF and the association with clinical and economic outcomes. An extensive search (1/2010–4/2020) of MEDLINE, the Cochrane Library, conference proceedings, and health technology assessments (HTAs) was conducted. Studies must have evaluated rates of nontreatment or undertreatment in NVAF. Nontreatment was defined as absence of OACs (but with possible antiplatelet treatment), while undertreatment was defined as treatment with only antiplatelet agents. Sixteen studies met our inclusion criteria. Rates of nontreatment for patients with elevated stroke risk ranged from 2.0–51.1%, while rates of undertreatment ranged from 10.0–45.1%. The clinical benefits of anticoagulation were reported in the evaluated studies with reductions in stroke and mortality outcomes observed among patients treated with anticoagulants compared to untreated or undertreated patients. Adverse events associated with all bleeding types (i.e. hemorrhagic stroke, major bleeding or gastrointestinal hemorrhaging) were found to be higher for warfarin patients compared to untreated patients in real-world practice. Healthcare resource utilization was found to be lower among patients highly-adherent to warfarin compared to untreated patients. Rates of nontreatment and undertreatment among NVAF patients remain high and are associated with preventable cardiovascular events and death. Strategies to increase rates of treatment may improve clinical outcomes.

description: Functional tissues generated under in vitro conditions are urgently needed in biomedical research. However, the engineering of tissues is rather difficult, since their development is influenced by numerous parameters. In consequence, a versatile culture system was developed to respond the unmet needs.Optimal adhesion for cells in this system is reached by the selection of individual biomaterials. To protect cells during handling and culture, the biomaterial is mounted onto a MINUSHEET(R) tissue carrier. While adherence of cells takes place in the static environment of a 24 well culture plate, generation of tissues is accomplished in one of several available perfusion culture containers. In the basic version a continuous flow of always fresh culture medium is provided to the developing tissue. In a gradient perfusion culture container epithelia are exposed to different fluids at the luminal and basal sides. Another special container with a transparent lid and base enables microscopic visualization of ongoing tissue development. A further container exhibits a flexible silicone lid to apply force onto the developing tissue thereby mimicking mechanical load that is required for developing connective and muscular tissue. Finally, stem/progenitor cells are kept at the interface of an artificial polyester interstitium within a perfusion culture container offering for example an optimal environment for the spatial development of renal tubules.The system presented here was evaluated by various research groups. As a result a variety of publications including most interesting applications were published. In the present paper these data were reviewed and analyzed. All of the results point out that the cell biological profile of engineered tissues can be strongly improved, when the introduced perfusion culture technique is applied in combination with specific biomaterials supporting primary adhesion of cells.

Guided by the projected BCS framework, the energy is written as a functional of occupation numbers. It is shown to generalize the BCS approach and to provide an alternative to Variation After Projection framework. Illustrations of the new approach are given for the pairing Hamiltonian for various particle numbers and coupling strengths. In all case, a very good agreement with the exact solution is found.

description: In information systems, a system is analyzed using a modeling tool. Analysis is an important phase prior to implementation in order to obtain the correct requirements of the system. During the requirements phase, the software requirements specification (SRS) is used to specify the system requirements. Then, this requirements specification is used to implement the system. The requirements specification can be represented using either a structure approach or an object-oriented approach. A UML (Unified Modeling Language) specification is a well-known for representation of requirements specification in an object-oriented approach. In this paper, we present one case study and discuss how mapping from UML specification into implementation is done. The case study does not require advanced programming skills. However, it does require familiarity in creating and instantiating classes, object-oriented programming with inheritance, data structure, file processing and control loop. For the case study, UML specification is used in requirements phase and Borland C++ is used in implementation phase. Based on the case study, it shows that the proposed approach improved the understanding of mapping from UML specification into implementation.

description: An unexpected Minkowskian solution of the equation of General Relativity (Einstein-1915) is trivial because it simply means that both members of the equation are equal to zero. However, if alternatively, one considers the complete equation with a non-zero (cosmological constant (Einstein-1917), a Minkowskian solution is no longer trivial because it amounts to impose a constraint on the right hand side of the equation (i.e. a non-null stress-energy tensor). If furthermore one identifies (as usual) this tensor to the one of a perfect fluid, one finds that this fluid has a positive energy density and a negative pressure. We discover finally an expanding Universal Minkowskian fluid (Flat Universe) that has not only dynamical properties (acceleration) but also optical properties that are connected with Doppler Redshift. Einstein special relativity in 1905 consisted in dissolving a ghost: the old electromagnetic ether; our relativistic approach involves also the dissolution of a ghost: the Dark Dnergy. This new cosmological ether becomes a pure relativistic effect of Minkowskian solution with CC.

description: To reveal the extent of obesity in a single healthcare system and provide a blueprint for other health systems to perform similar analyses, this study describes characteristics and weight change patterns of patients classified with overweight and obesity at a large integrated delivery network (IDN) in the South-Central United States. A descriptive, observational, retrospective study was conducted using electronic medical records and claims data. Patients were ≥18 years old, body mass index (BMI) ≥27 kg/m2, and continuously enrolled in the IDN plan for ≥6 months before and ≥12 months after the index date. Demographics, comorbidities, BMI, and weight were collected. Weight changes were assessed annually, and anti-obesity medications (AOM) use was also captured. A total of 36,430 eligible patients were identified. A subset of 22,712 patients was continuously enrolled for the entire study period (mean age: 57.2) and were primarily white (83.3%) and commercially insured (54.3%). Most patients were categorized as overweight (40.1%) or obesity class I (32.5%) at baseline. At years 1 and 4 post-index, patients who maintained index weight (±3%) was 56.2% and 37.0%, respectively, whereas weight gain (≥3% increase) was 23.7% and 33.3%, respectively. AOM use (1.1%) primarily consisted of phentermine-hydrochloride (n = 114, 0.5%) and orlistat (n = 115, 0.5%). An increasing proportion of patients gained weight over time, combined with low AOM use, emphasizing the need for weight-loss interventions in this population. Findings from this study provide a foundation for health systems to perform similar analyses.

description: Background Mollusc shells are commonly investigated using high-resolution imaging techniques based on cryo-fixation. Less detailed information is available regarding the light-optical properties. Sea shells of Haliotis pulcherina were embedded for polishing in defined orientations in order to investigate the interface between prismatic calcite and nacreous aragonite by standard materialographic methods. A polished thin section of the interface was prepared with a defined thickness of 60 mum for quantitative birefringence analysis using polarized light and LC-PolScope microscopy. Scanning electron microscopy images were obtained for comparison. In order to study structural-mechanical relationships, nanoindentation experiments were performed. Results Incident light microscopy revealed a super-structure in semi-transparent regions of the polished cross-section under a defined angle. This super-structure is not visible in transmitted birefringence analysis due to the blurred polarization of small nacre platelets and numerous organic interfaces. The relative orientation and homogeneity of calcite prisms was directly identified, some of them with their optical axes exactly normal to the imaging plane. Co-oriented "prism colonies" were identified by polarized light analyses. The nacreous super-structure was also visualized by secondary electron imaging under defined angles. The domains of the super-structure were interpreted to consist of crystallographically aligned platelet stacks. Nanoindentation experiments showed that mechanical properties changed with the same periodicity as the domain size. Conclusions In this study, we have demonstrated that insights into the growth mechanisms of nacre can be obtained by conventional light-optical methods. For example, we observed super-structures formed by co-oriented nacre platelets as previously identified using X-ray Photo-electron Emission Microscopy (X-PEEM) [Gilbert et al., Journal of the American Chemical Society 2008, 130:17519--17527]. Polarized optical microscopy revealed unprecedented super-structures in the calcitic shell part. This bears, in principle, the potential for in vivo studies, which might be useful for investigating the growth modes of nacre and other shell types.

Genomic and functional characteristics of DNA copy number variants associated with developmental abnormalities
Creators: name: Bagheri, Hani
Publisher: name: University of British Columbia

description: Small gains and losses of chromosomal DNA, called copy number variants (CNVs), are the cause of many human developmental abnormalities detected before or after birth. Clinically-significant CNVs are found in 2-6% of developmentally arrested embryos and fetuses (termed miscarriage) and in ~15% of children with postnatal developmental abnormalities, typically including abnormal brain function and leading to neuro-developmental delay (NDD). The overall goal of my PhD project was to characterize CNVs found in both miscarriages and in children with NDD in order to identify candidate genes that cause these two aspects of abnormal development. I used a multi-faceted approach consisting of bioinformatics, human cell-line analysis and transgenic animal model investigations. I characterized CNVs reported in miscarriages from literature as well as from our laboratory by using bioinformatics approaches to determine the CNVs size, gene content, gene density and function, known gene knockout murine phenotype, and biological pathway enrichment for all miscarriage CNV genes. My analysis identified several genes from miscarriage CNVs with important functions during prenatal development and pregnancy (e.g. CDKN1C and TIMP2) and enrichment of genes from miscarriage CNVs in biological pathways and processes relevant to embryo/fetal development and feto-maternal interaction (e.g. immune response). For discovery of candidate genes responsible for childhood NDD, I characterized CNVs mapping to a chromosome region, 2p15p16.1, which are known to be associated with multiple postnatal developmental abnormalities and NDD (termed 2p15p16.1 microdeletion syndrome). I performed detailed phenotype and CNV analysis of 33 patients with 2p15p16.1 microdeletions and identified 3 candidate genes (XPO1, REL, and BCL11A) for the developmental problems. By studying their expression in patient cell-lines as well as phenotypic consequences of the loss or gain of their expression in zebrafish, I confirmed their role in developmental abnormalities associated with this syndrome. I have also explored the role of non-coding sequences from this CNV in regulation of one of the candidate genes, BCL11A. The results of my study provide a blueprint for identification of genes with a role in abnormal development by characterizing CNVs. Understanding the cause of the developmental abnormalities opens paths for exploring possibilities for their improved diagnosis, prevention, and potential cure.

Consider the adjoint-orbit space $M=\{ {\rm Ad}_g(H_1),~g \in G \}$, identified with the homogeneous space $G/L$ where $L=\{ g \in G:~{\rm Ad}_g(H_1)=H_1\}$. We prove that the `coordinate functions' $\{ f_i, i=1, \ldots, n \}$, (where $f_i(g):=λ_i({\rm Ad}_g(H_1))$, $\{ λ_1, \ldots, λ_n\}$ is basis of $\clg^\prime$) are `quadratically independent' in the sense that they do not satisfy any nontrivial homogeneous quadratic relations among them. Using this, it is proved that there is no genuine compact quantum group which can act faithtully on $C(M)$ such that the action leaves invariant the linear span of the above cordinate functions. As a corollary, it is also shown that any compact quantum group having a faithful action on the noncommutative manifold obtained by Rieffel deformation of $M$ satisfying a similar `linearity' condition must be a Rieffel-Wang type deformation of some compact group.

On the Birch and Swinnerton-Dyer conjecture and ERG Theory.pdf

description: We prove the integrality and modularity of the Birch and Swinnerton-Dyer conjecture with ERG Theory. Inspection of the conjecture shows that it is a phenomenological model. Thus, a solution could be found through regression analysis. Numerical verification is possible through nominative determinism/visibility theory. By adding adaptive learning (AL) to the model, the model admits an important time variation in beliefs, which would be ruled out under rational expectations. Entropy can be given from a detailed molecular analysis of the system. In summary, perception consists of the selection, organization, and interpretation of stimuli. These factors affect the conduct of work. We include two inequalities on the log-volume change associated to appropriately chosen deformations.

Breathing Oscillations in Bose - Fermi Mixing Gases with Yb atoms in the Largely Prolate Deformed Traps

description: We study the breathing oscillations in bose-fermi mixtures with Yb isotopes in the largely prolate deformed trap, which are realized by Kyoto group. We choose the three combinations of the Yb isotopes, Yb170-Yb171, Yb170-Yb173 and Yb174-Yb173, whose boson-fermion interactions are weakly repulsive, strongly attractive and strongly repulsive. The collective oscillations in the deformed trap are calculated in the dynamical time-development approach, which is formulated with the time-dependent Gross-Pitaevskii and the Vlasov equations. We analyze the results in the time-development approach with the intrinsic oscillation modes of the deformed system, which are obtained using the scaling method, and show that the damping and forced-oscillation effects of the intrinsic modes give time-variation of oscillations, especially, in the fermion transverse mode.

Exploring the relationship between cannabis use expectancies and the initiation of cannabis use among Canadian adolescents
Creators: name: Hapsari, Ayu Pinky
Publisher: name: University of British Columbia
Year: 2017

description: BACKGROUND: Canada has one of the highest reported rates of adolescent cannabis use among industrialized countries and plans to legalize recreational cannabis use for adults. However, research suggesting that cannabis use during adolescence may be associated with health risks has led to a call for monitoring the impact of legalization on use by adolescents. Based on evidence that identifies outcome expectancies (expectations regarding the effect of substance use) and intention to use as significant predictors of tobacco smoking and alcohol drinking among adolescence, monitoring efforts associated with the upcoming cannabis regulation may benefit from the use of similar predictors. OBJECTIVE: This study aimed to examine the validity of the Marijuana Effect Expectancy Questionnaire-Brief (MEEQ-B) as a measure of cannabis use expectancies and then examine the relationship between expectancies and the intention to use cannabis, as well as their predictive utility as indicators of future cannabis use. METHODS: Data were collected from 1592 high school students aged 14-16 years participating in British Columbia Adolescent Substance Use Survey during the 2011/2012 school year. Confirmatory factor analysis was conducted to evaluate the psychometric structure of the MEEQ-B, and generalized estimating equation (GEE) using logit link was used to examine the relationship between expectancies, intention to try, and initiation and lifetime use of cannabis. RESULTS: The initial two-factor structure of MEEQ-B did not provide a good fit to the data. However, cross-loading item 6 onto both positive and negative expectancies factors resulted in a good fit. After controlling for gender, ethnicity, age, and socio-economic status, results of the GEE indicated that positive expectancies were significantly and positively associated with lifetime cannabis use (AOR: 2.47), and initiation of cannabis within six months (AOR: 1.9), whereas the reverse trend was found for negative expectancies. Having at least some intention to try cannabis increased the odds of cannabis initiation by seven times (AOR: 6.91). CONCLUSION: Revision to the MEEQ-B questions is needed to reliably measure expectancies related to adolescent cannabis use. In support of Integrative Model of Behavioral Prediction, expectancies and intention to use can be utilized as upstream indicators for future cannabis initiation.
Einstein's `Zürich Notebook' and his Journey to General Relativity

description: On the basis of his `Zürich Notebook' I shall describe a particularly fruitful phase in Einstein's struggle on the way to general relativity. These research notes are an extremely illuminating source for understanding Einstein's main physical arguments and conceptual difficulties that delayed his discovery of general relativity by about three years. Together with the `Ent\-wurf' theory in collaboration with Marcel Grossmann, these notes also show that the final theory was missed late in 1912 within a hair's breadth. The Einstein-Grossmann theory, published almost exactly hundred years ago, contains, however, virtually all essential elements of Einstein's definite gravi\-tation theory. This should become obvious by our streamlined presentation of the final phase in November 1915 that culminated with the definite field equations.

description: A report on the recent next-to-leading order QCD calculations to t anti-t b anti-b and t anti-t + 2j processes at the CERN Large Hardon Collider is presented. Results for integrated and differential cross sections are given. A significant reduction of the scale dependence is observed in both cases, which indicates that the perturbative expansion is well under control. The results are obtained in the framework of the HELAC-NLO system.

Good inclusive practices in video conferences

description: The health crisis that the world has been going through since the end of 2019 has imposed a profound transformation of communication modes. Video-conferencing has become a tool of our daily life with a multitude of different software. Over the past year, we have had time to familiarize ourselves with these techniques and it is time to question our practices. If the format of video- conferences is different from that of traditional conferences, gender bias is still present but expressed differently. Therefore, we thought it would be useful to combine the charter for gender fairness in conferences with a specific practical guide. The aim of this guide is to raise awareness of certain biases and to propose solutions so that practices change before they become habits.

description: Any sequence of properly embedded minimal disks in an open subset U of Euclidean 3-space has a subsequence such that the curvatures blow up on a relatively closed subset K of U and such that the disks converge in the complement of K to a minimal lamination of U\K. Assuming results of Colding-Minicozzi and an extension due to Meeks, we prove that such a blow-up set K must be contained in a C^1 embedded curve.
