description: While laparoscopic liver resection is less prone to complications and maintains patient outcomes compared to traditional open surgery, its complexity hinders widespread adoption due to challenges in representing the liver's internal structure. Laparoscopic intraoperative ultrasound offers efficient, cost-effective and radiation-free guidance. Our objective is to aid physicians in identifying internal liver structures using laparoscopic intraoperative ultrasound. We propose a patient-specific approach using preoperative 3D ultrasound liver volume to train a deep learning model for real-time identification of portal tree and branch structures. Our personalized AI model, validated on ex vivo swine livers, achieved superior precision (0.95) and recall (0.93) compared to surgeons, laying groundwork for precise vessel identification in ultrasound-based liver resection. Its adaptability and potential clinical impact promise to advance surgical interventions and improve patient care.

description: War was declared when my uncle, Rex Compton, was still at school (sixth form) and he enlisted in the 10th Essex Regiment straight away as a private. The Regiment was one of the first 'volunteer' battalions to be deployed in the Gallipoli campaign, until the successful moonlight evacuation in December 1915, by which time he was acting as temporary Captain. The Regiment went first to Lemnos and then to Alexandria.

My brother came across this hand-made embroidered needle book when clearing out my parents' house only a week or two ago. Not only is it beautifully made, but it contains a fabric order number tab, a bit like one you'd sew in a child's school uniform, but from F Phillips & Co, Cairo and Alexandria, dated 4 March 1916 and made out to 2nd Lieutenant Compton.

Rex and his older brother, Guy, died on the Western Front near Ypres a couple of weeks apart in July/August 1917, so how did this survive? Was it made for him by one of his loving younger sisters? Did he leave it behind by accident when on leave or for safe keeping? We will never know.

description: The presence of a confining boundary can modify the local structure of a liquid markedly. In addition, small samples of finite size are known to exhibit systematic deviations of thermodynamic quantities relative to their bulk values. Here, we consider the static structure factor of a liquid sample in slab geometry with open boundaries at the surfaces, which can be thought of as virtually cutting out the sample from a macroscopically large, homogeneous fluid. This situation is a relevant limit for the interpretation of grazing-incidence diffraction experiments at liquid interfaces and films. We derive an exact, closed expression for the slab structure factor, with the bulk structure factor as the only input. This shows that such free boundary conditions cause significant differences between the two structure factors, in particular at small wavenumbers. An asymptotic analysis of this result yields the scaling exponent and an accurate, useful approximation of these finite-size corrections. Furthermore, the open boundaries permit the interpretation of the slab as an open system, supporting particle exchange with a reservoir. We relate the slab structure factor to the particle number fluctuations and discuss conditions under which the subvolume of the slab represents a grand canonical ensemble with chemical potential $μ$ and temperature $T$. Thus, the open slab serves as a test-bed for the small-system thermodynamics in a $μT$ reservoir. We provide a microscopically justified and exact result for the size dependence of the isothermal compressibility. Our findings are corroborated by simulation data for Lennard-Jones liquids at two representative temperatures.

description: Observations of the radio galaxy MRC 0316-257 at z=3.13 and the surrounding field are presented. Using narrow- and broad-band imaging obtained with the VLT, 77 candidate Ly-alpha emitters with a rest-frame equivalent width of > 15 A were selected in a ~7'x7' field around the radio galaxy. Spectroscopy of 40 candidate emitters resulted in the discovery of 33 emission line galaxies of which 31 are Ly-alpha emitters with redshifts similar to that of the radio galaxy, while the remaining two galaxies turned out to be [OII] emitters. The Ly-alpha profiles have widths (FWHM) in the range of 120-800 km/s, with a median of 260 km/s. Where the signal-to-noise was large enough, the Ly-alpha profiles were found to be asymmetric, with apparent absorption troughs blueward of the profile peaks, indicative of absorption along the line of sight of an HI mass of at least 2x10^2 - 5x10^4 M_sun. The properties of the Ly-alpha galaxies (faint, blue and small) are consistent with young star forming galaxies which are still nearly dust free. The volume density of Ly-alpha emitting galaxies in the field around MRC 0316-257 is a factor of 3.3+0.5-0.4 larger compared with the density of field Ly-alpha emitters at that redshift. The velocity distribution of the spectroscopically confirmed emitters has a FWHM of 1510 km/s, which is substantially smaller than the width of the narrow-band filter (FWHM ~ 3500 km/s). The peak of the velocity distribution is located within 200 km/s of the redshift of the radio galaxy. We conclude that the confirmed Ly-alpha emitters are members of a protocluster of galaxies at z~3.13. The size of the protocluster is larger than 3.3x3.3 Mpc^2. The mass of this structure is estimated to be > 3-6x10^14 M_sun and could be the progenitor of a cluster of galaxies similar to e.g. the Virgo cluster. (Abridged)

description: We combine photometric and spectroscopic data on twelve modes excited in FG Vir to determine their spherical harmonic degrees, $\ell$, and to obtain constraints on the star model. The effective temperature consistent with the mean colours and the pulsation data is about 7200K. In six cases, the $\ell$ identification is unique with above 80 % probability. Two modes are identified as radial. Simultaneously with $\ell$, we determine a complex parameter $f$ which probes subphotospheric stellar layers. Comparing its values with those derived from models assuming different treatment of convection, we find evidence that convective transport in the envelope of this star is inefficient.

description: Conventional microwave remote sensing/imaging of through-the-wall objects made of different materials is usually performed at frequencies below 3 GHz that provide relatively low spatial resolution. In this paper, we evaluate the ability and sensitivity of high-frequency microwave or millimeter wave standoff sensing of through-the-wall objects to achieve high spatial resolution. The target under study is a sandwich structure consisting of different object materials placed between two wall blocks. An Agilent PNA-X series (model N5245A) vector network analyzer is used to sweep over the entire Ka-band (26.5 GHz to 40 GHz). The beam is then directed to a standard rectangular horn antenna and collimated by a 6-inch-diameter Gaussian lens towards the sandwich structure (wall block/object/wall block). The reflected electromagnetic wave is picked up by the same system as the complex S-parameter S11. Both amplitude and phase of the reflected signal are used to recognize different materials sandwiched between the cement blocks. The experimental results are compared with the theoretical calculations, which show satisfactory agreement for the cases evaluated in this work.

Subjects-in-interaction version 3.0 : an intellectual system for modern language student teachers to appropriate multiliteracies as designers and interpreters of media texts
Creators: name: Beers, Maggie
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation, which draws on the fields of critical theory, sociolinguistic theory, teacher education, and human-computer interaction, examines issues of culture and intercultural understanding, critical multiliteracies, learning in general and, specifically, the role of new media in the creation and interpretation of (learning) cultures. Critical modern language education theorists advocate engaging in ethnographic studies of one's own and the target language culture as a way to shed traditional, static, product-based notions of culture for postmodern, dynamic, process-based interpretations of culture(s). To this end, how can teacher educators prepare student teachers to be reflexive about their own classroom practice? In this approach, sixty secondary-level student teachers made short digital movies on their cultural interpretations of an object of their choice, such as cars. They filmed each other and were filmed as they worked and reflected on their movies and then used an online video analysis tool to share, annotate and critique the digital representations of their processes and products in relation to the course content. The participants assumed a variety of research roles, such as research initiators, qualitative researchers, video ethnographers, reflective practitioners and beta-testers of previously unreleased software Multimedia profiles of eight participants, presented on an accompanying CD-ROM, illustrate learning experiences that occurred throughout the group. They found it challenging to reconcile their prior schema and new concepts; confusing to develop a teaching approach while their basic assumptions were evolving; exciting to use state of the art tools and take on research roles; rewarding to participate in forums for productive reflection and discover new capacities; effective for making abstract ideas concrete; and empowering to appropriate the technical and intellectual skills to carry out similar projects. This study points to a need for a pedagogical shift in preparing modern language student teachers which positions them to claim the classroom as their own. This includes claiming the right to: include culture in a language driven classroom; choose their own media materials; determine their own curriculum within standardized curricular and textbook guidelines; use non-traditional language teaching approaches; and hold high expectations for their students for critical thinking and use of the target language.
Hydrodynamic Properties of the Sun's Giant Cellular Flows

description: Measurements of the large cellular flows on the Sun were made by local correlation tracking of supergranules seen in full-disk Doppler images obtained by the HMI instrument on the NASA SDO satellite. The hourly measurements were averaged over 34 days to produce daily maps of the latitudinal and longitudinal velocities. While flows at all latitudes are largely in the form of vortices with left-handed helicity in the north and right-handed helicity in the south, there are key distinctions between the low latitude and high latitudes cells. The low latitude cells have roughly circular shapes, lifetimes of about one month, rotate nearly rigidly, do not drift in latitude, and do not exhibit any correlation between longitudinal and latitudinal flow. The high latitude cells have long extensions that spiral inward toward the poles. They have lifetimes of several months, rotate differentially with latitude, drift poleward at speeds approaching 2 m s$^{-1}$, and have a strong correlation between prograde and equatorward flows. Spherical harmonic spectral analyses confirm that the flows are dominated by the curl component with RMS velocities of about 12 m s$^{-1}$ at wavenumber $\ell$ = 10. Fourier transforms in time indicate two notable components - an $m = \pm\ell$ feature representing the low latitude component and an $m = \pm1$ feature representing the high latitude component. The dispersion relation for the low latitude component is well represented by that derived for Rossby waves. The high latitude component has a constant temporal frequency for all $\ell$ indicating features advected by differential rotation at rates representative of the base of the convection zone high latitudes. The poleward motions of these features further suggest that the high latitude meridional flow at the base of the convection zone is poleward - not equatorward.

description: A large body of theoretical and computational work shows that jets - modelled as magnetized disk winds - exert an external torque on their underlying disks that can efficiently remove angular momentum and act as major drivers of disk accretion. These predictions have recently been confirmed in direct HST measurements of the jet rotation and angular momentum transport in low mass protostellar systems. We review the theory of disc winds and show that their physics is universal and scales to jets from both low and high mass star forming regions. This explains the observed properties of outflows in massive star forming regions, before the central massive star generates an ultracompact HII region. We also discuss the recent numerical studies on the formation of massive accretion disks and outflows through gravitational collapse, including our own work on 3D Adaptive Mesh simulations (using the FLASH code) of the hydromagnetic collapse of an initial rotating, and cooling Bonner-Ebert sphere. Magnetized collapse gives rise to outflows. Our own simulations show that both a jet-like disk wind on sub AU scales, and a larger scale molecular outflow occur (Banerjee and Pudritz 2005).

description: A novel dose calculation approach was designed based on the application of LSTM network that processes the 3D patient/phantom geometry as a sequence of 2D computed tomography input slices yielding a corresponding sequence of 2D slices that forms the respective 3D dose distribution. LSTM networks can propagate information effectively in one direction, resulting in a model that can properly imitate the mechanisms of proton interaction in matter. The study is centered on predicting dose on a single pencil beam level, avoiding the averaging effects in treatment plans comprised of thousands pencil beams. Moreover, such approach allows straightforward integration into today's treatment planning systems' inverse planning optimization process. The ground truth training data was prepared with Monte Carlo simulations for both phantom and patient studies by simulating different pencil beams impinging from random gantry angles through the patient geometry. For model training, 10'000 Monte Carlo simulations were prepared for the phantom study, and 4'000 simulations were prepared for the patient study. The trained LSTM model was able to achieve a 99.29 % gamma-index pass rate ([0.5 %, 1 mm]) accuracy on the set-aside test set for the phantom study, and a 99.33 % gamma-index pass rate ([0.5 %, 2 mm]) for the set-aside test set for the patient study. These results were achieved for each pencil beam in 6-23 ms. The average Monte Carlo simulation run-time using Topas was 1160 s. The generalization of the model was verified by testing for 5 previously unseen lung cancer patients. LSTM networks are well suited for proton therapy dose calculation tasks. However, further work needs to be performed to generalize the proposed approach to clinical applications, primarily to be implemented for various energies, patient sites, and CT resolutions/scanners.

Observed Metallicity Dependence of Winds from WR stars

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A review of observational evidence in favour of a metallicity dependence of WN and WC stars is presented. New near-IR studies of Milky Way, LMC and SMC early-type WN stars are presented, with weake winds amongst WN stars containing hydrogen. A metallicity dependence is supported for WN stars with hydrogen, with dM/dt propto Z^alpha with alpha approx 0.8 +/- 0.2 The influence of CNO content upon WN subtypes is discussed. Earlier WN spectral types are expected (and observed) at lower metallicity due to the abundance sensitivity of NIII-IV classification diagnostics. Recent physical and chemical results of WC stars in the Milky Way and LMC are discussed, suggesting a metallicity dependence of alpha approx 0.6 +/- 0.1. Earlier WC spectral types are predicted (and observed) in lower metallicity galaxies, due to the dependence of the CIII classification diagnostic on wind density. WO stars reveal lower wind velocities at lower metallicity, whilst the situation for WN and WC stars is unclear. Finally, the influence of a WR metallicity dependence upon the ionizing flux distributions and optical line luminosities is addressed, with particular regard to I Zw 18. Weaker winds at low metallicity would imply harder ionizing flux distributions and lower line luminosities, arguing for an substantially increased number of WR stars with respect to standard calibrations, exacerbating difficulties with single star evolutionary models at very low metallicity.

Academic presentations : exploring the second language socialization of international graduate students across disciplines
Creators: name: Zappa Hollman, Sandra Carolina
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the language socialization of international students in the graduate school context of a western Canadian university. Focusing on one pervasive speech event, academic presentations (APs), this study explored the role this socioculturally organized activity played in facilitating students' linguistic and sociocultural development, and how it aided them in negotiating their entry into the academic world. The participants in this study included 55 graduate students and nine course instructors. Thirty seven students were native speakers (NSs) of English, while the remaining 18- -the focal participants of this study—were non-native speakers of English (NNSs). The sites were seven graduate courses in six different departments in three different faculties (Faculty of Medicine, Faculty o f Arts, and Faculty o f Applied Science). A qualitative approach was employed, and thus multiple kinds of data were gathered over a four-month period. Data collection methods included: (a) open-ended interviews with participants; (b) tape-recorded observations of APs; (c) researcher's fieldnotes of APs; and (d) collection of written documents (e.g., course outlines). Data were analyzed following Bogdan and Biklen (1992) by identifying major and minor themes while iteratively going over the data. A comparison of APs across disciplines is included, examining aspects such as A P content, sequence, length, and format. As well, an analysis of the qualities promoted in each field and of the multiple purposes APs fulfil is provided and related to the complex socialization (i.e., both linguistic and sociocultural) of international graduate students. Findings of the study suggested that APs are a complex task whose meaning is not fixed, but rather is determined by the interplay of the broad context of the academic world, the micro-context of each community of practice, and ultimately by each individual. With regard to the language socialization 6f NNSs, APs challenged students in both linguistic and sociocultural ways. However, by observing, participating in, and reflecting on APs, students gained increased membership and competence within their academic communities.

description: We generalize the adiabatic approximation to the case of open quantum systems, in the joint limit of slow change and weak open system disturbances. We show that the approximation is ``physically reasonable'' as under wide conditions it leads to a completely positive evolution, if the original master equation can be written on a time-dependent Lindblad form. We demonstrate the approximation for a non-Abelian holonomic implementation of the Hadamard gate, disturbed by a decoherence process. We compare the resulting approximate evolution with numerical simulations of the exact equation.

description: Understanding the models that characterize the thermal dynamics in a smart building is important for the comfort of its occupants and for its energy optimization. A significant amount of research has attempted to utilize thermodynamics (physical) models for smart building control, but these approaches remain challenging due to the stochastic nature of the intermittent environmental disturbances. This paper presents a novel data-driven approach for indoor thermal model inference, which combines an Autoregressive Moving Average with eXogenous inputs model (ARMAX) with a Normalized Mutual Information scheme (NMI). Based on this information-theoretic method, NMI, causal dependencies between the indoor temperature and exogenous inputs are explicitly obtained as a guideline for the ARMAX model to find the dominating inputs. For validation, we use three datasets based on building energy systems-against which we compare our method to an autoregressive model with exogenous inputs (ARX), a regularized ARMAX model, and state-space models.

description: The purpose of this study was to identify the values Saskatchewan residents place on their Woodland Caribou conservation programs. Using contingent valuation methods, individual values for maintaining caribou numbers within Millar Western-NorSask Forest Management Licence agreement area were estimated. Using these value estimates, societal benefits were estimated for the implementation of a woodland caribou maintenance program within the forest licence agreement area. The data used in this study were collected using a mailout survey to Saskatchewan residents. Two contingent valuation formats were used, the opened ended willingness to pay and the dichotomous choice. A number of question structures were employed in order to judge the sensitivity of the valuation to the design. In all, 9 different versions of the contingent valuation question were used in a randomized design strategy. The resulting welfare measures for the implementation of the caribou maintenance program were somewhat variable. The open ended format produced the lowest estimates, while the dichotomous choice estimates were higher and showed a higher degree of variability. This variability may be due to the presence of the ordering or whole-part effects. The values elicited for the conservation program using the open ended approach average approximately $15.00 per person per year. These values, when aggregated over the provincial population, result in an annual benefit of the woodland caribou conservation program of about $10M. These are the most conservative of the estimates, suggesting that woodland caribou conservation is very important to Saskatchewan residents.

description: The effect induced by an environment on a composite quantum system is studied. The model considers the composite system as comprised by a subsystem A coupled to a subsystem B which is also coupled to an external environment. We study all possible four combinations of subsystems A and B made up with a harmonic oscillator and an upside down oscillator. We analyzed the decoherence suffered by subsystem A due to an effective environment composed by subsystem B and the external reservoir. In all the cases we found that subsystem A decoheres even though it interacts with the environment only through its sole coupling to B. However, the effectiveness of the diffusion depends on the unstable nature of subsystem A and B. Therefore, the role of this degree of freedom in the effective environment is analyzed in detail

description: Asia is the second largest market for the Canadian agri-food exports after the United States market. The competition in Asia has become more intensive in recent years as the agri-food sector in developed nations such as Australia, Canada, Europe, and the United States has increasingly relied on exports for growth because of their own slow-growing domestic food consumption. How did the performance of Canadian agri-food exports to Asia measure up to the performances of its main competitors? This research attempts to identify Canada's competitiveness in agri-food exports to Asia, relative to Canada's main competitors. The analysis is based on the 1980-97 trade data from the World Trade Analyzer (WTA), produced by the International Trade Division of Statistics Canada. According to their average market shares during the 1980-97 period, Canada's main competitors in Asia are the United States, Europe, Australia, China, Thailand, Malaysia, Taiwan, Indonesia and New Zealand. To assess each country's competitiveness, this research applies the Constant Market Share (CMS) model. The change in each country's exports is primarily divided into the structural and the competitive effects. The exporting country with larger competitive effect is considered to be more competitive. The key results are: * All exporting countries increased their agri-food exports to Asia during the 1980-97 period. The increase in their exports to Asia can be primarily attributed to the structural effect - particularly to the large increase of total Asian agri-food imports (growth effect). * Canada ranked second after China in terms of competitive effect during the 1980-1997 period. Indonesia and Thailand also exhibit strong competitiveness in Asia. Canada's traditional competitors such as the United States, Europe, Australia, and New Zealand were found to be non-competitive. * Compared with other competitors in the Asian market, Canada exhibit two areas of weakness. First, Canada did not concentrate their agri-food exports to Asia on fast-growing commodities such as consumer-ready products. Second, Canada's competitiveness was deteriorated in the processed intermediate goods in Korea and South Asia, the consumer-ready goods in Japan and Asia 7, and the bulk commodities in Taiwan. If Asia was considered to be a target region for Canadian agri-food exports, one would need not only to know the exporting strategies that will be adopted by countries such as the United States, Europe, Australia, and New Zealand, but also those adopted by countries such as China, Indonesia and Thailand. In order for Canada to maintain and improve its export performance in Asia in the future, it will be most effective if Canada could increase its market shares of processed intermediate goods in Korea and South Asia, the consumer-ready goods in Japan and Asia 7, and the bulk commodities in Taiwan.

description: The effects of an extra $Z'$ gauge boson with family nonuniversal fermion couplings on the rare top quark decay $t --> c $gamma$ are first examined in a model independent way and then in the minimal 331 model. It is found that the respective branching fraction is at most of the order of $10^{-8}$ for $m_{Z'}=500$ GeV and dramatically decreases for a heavier $Z'$ boson. This results is in sharp contrast with a previous evaluation of this decay in the context of topcolor assisted technicolor models, which found that $B(t --> c γ)\sim 10^{-6}$ for $m_{Z'}=1$ TeV.

description: This study evaluates the risk and returns to cattle feeding in Alberta from the application of alternative marketing and pricing strategies. Feedlot finishing of 650 pound calves and 800 pound yearlings is modeled over the years from 1980 to 1993. The results of the study are based on the domestic and US marketing of live cattle using traditional cash marketing, futures contracts, put options, and forward production contracting systems. Use of the Western Domestic Feed Barley contract is also simulated. The results showed that barley price changes produced relatively small return changes compared to feeder and fat cattle price changes. An important source of return risk was found to be basis risk. Production contracting strategies which eliminated basis risk were found to provide the best returns in a market based risk-return comparison. The use of put options did not add value to cattle feeding investments.
Loss-of-entanglement prediction of a controlled-PHASE gate in the framework of steepest-entropy-ascent quantum thermodynamics

description: As has been shown elsewhere, a reasonable model of the loss of entanglement or correlation that occurs in quantum computations is one which assumes that they can effectively be predicted by a framework that presupposes the presence of irreversibilities internal to the system. It is based on the steepest-entropy-ascent principle and is used here to reproduce the behavior of a controlled-PHASE gate in good agreement with experimental data. The results show that the loss of entanglement predicted is related to the irreversibilities in a nontrivial way, providing a possible alternative approach that warrants exploration to that conventionally used to predict the loss of entanglement. The results provide a means for understanding this loss in quantum protocols from a nonequilibrium thermodynamic standpoint. This framework permits the development of strategies for extending either the maximum fidelity of the computation or the entanglement time.

description: This study examines the factors affecting choice of pricing and payment practices by traditional marketing and new generation co-operatives for commodities delivered by their members. These factors include the demographic variables related to type of co-operative organization, level of competition in commodity market, and risk-return perceptions of members and co-operatives. Data for the analysis were obtained through a mail survey. Questionnaires were send to one hundred and ninety five (195) co-operatives in mid-west states of the U.S.A. and Canada. Altogether 93 co-operatives responded to the survey. Mean score analysis, factor analysis and multinomial logit analysis were done. The results indicate that traditional marketing co-operatives are more likely to choose spot market cash price, while new generation co-operatives are more likely to choose pooling practices. Traditional marketing co-operatives appear to be concerned about the members' cash flow needs and members' uncertainty of return; they are also more responsive to increased competitive level in commodity market. New generation co-operatives are more concerned with avoiding the risk of co-operatives' operating deficits and survival of co-operatives. This has implications for new co-operatives just beginning in business.

The collaborative role of an ESL support teacher in a secondary school : supporting ESL students and content teachers utilizing integrated language and content instruction
Creators: name: Konnert, Michele Rand
Publisher: name: University of British Columbia
Year: 2009

description: This research project was conducted with social studies and English teachers and ESL students in mainstream classes at a secondary school in Richmond, B.C. over a seven-month period from September 1998 to March 1999. As an action researcher, I solved problems through team work and through following a cyclical process of 1. strategic planning, 2. action, 3. observation, evaluation and self-evaluation, and 4. critical and self-critical reflection on the cycle (McNiff, Lomax, & Whitehead, 1996). The findings included in this study are a definition of the ESL support role, effectiveness of the ESL support program, teacher collaboration, application of the ILC approach and the Knowledge Framework (Mohan, 1986), challenges and issues for content teachers and ESL students, and the dual role as support teacher and researcher. First, with regard to a definition of the ESL support role, ESL support teachers were viewed by myself and the administration as language development specialists who act as consultants, with a focus on co-teaching and individual instruction. Colleagues perceived the ESL support team as ESL trained teachers who must prove their effectiveness through action, rather than words, in content teachers' classrooms. ESL students viewed the ESL support teachers as a welcome support or unwelcome intruders. Second, with regard to the effectiveness of the ESL support program, the administration and I felt that the program provided exceptional support services to content teachers and ESL students. ESL students also felt that the ESL support program was very helpful. Colleagues, however, were initially skeptical of the program, but eventually valued the support. Third, collaboration increased over time as ESL support specialists worked in cooperative relationships with content teachers. Fourth, the ILC approach was selectively, and at times superficially, implemented in content courses. Also, the Knowledge Framework was the most successful teaching method for ESL support of content teachers and ESL students. Fifth, there were many challenges for content teachers, ESL learners, and ESL support specialists. One challenge was the lack of English spoken by our student population. Another concern was the appearance of passivity of ESL students. Also, assessment and evaluation of ESL students was very difficult for content teachers. Thus, content instructors needed to learn alternate assessment and evaluation strategies for their ESL learners. In addition, teachers wondered about their ESL students' comprehension and exam preparation. Lastly, tensions inevitably arose from the dual role as teacher and researcher.
Sun's retrograde motion and violation of even-odd cycle rule in sunspot activity
Creators: name: Javaraiah, J.
Publisher: name: arXiv

description: The sum of sunspots number over an odd numbered 11 yr sunspot cycle exceeds that of its preceding even numbered cycle, and it is well known as Gnevyshev and Ohl rule (or G--O rule) after the names of the authors who discovered it in 1948. The G--O rule can be used to predict the sum of sunspot numbers of a forthcoming odd cycle from that of its preceding even cycle. But this is not always possible because occasionally the G--O rule is violated. So far no plausible reason is known either for the G--O rule or the violation of this rule. Here we showed the epochs of the violation of the G--O rule are close to the epochs of the Sun's retrograde orbital motion about the centre of mass of the solar system (i.e., the epochs at which the orbital angular momentum of the Sun is weakly negative). Using this result easy to predict the epochs of violation of the G--O rule well in advance. We also showed that the solar equatorial rotation rate determined from sunspot group data during the period 1879--2004 is correlated/anti-correlated to the Sun's orbital torque during before/after 1945. We have found the existence of a statistically significant $\sim$ 17 yr periodicity in the solar equatorial rotation rate. The implications of these findings for understanding the mechanism behind the solar cycle and the solar-terrestrial relationship are discussed.
