description: We report measurements of the hydrodynamic drag force acting on a smooth sphere falling down under gravity to a plane decorated with microscopic periodic grooves. Both surfaces are lyophilic, so that a liquid (silicone oil) invades the surface texture being in the Wenzel state. A significant decrease in the hydrodynamic resistance force as compared with that predicted for two smooth surfaces is observed. To quantify the effect of roughness we use the effective no-slip boundary condition, which is applied at the imaginary smooth homogeneous isotropic surface located at an intermediate position between top and bottom of grooves. Such an effective condition fully characterizes the force reduction measured with the real surface, and the location of this effective plane is related to geometric parameters of the texture by a simple analytical formula.

ON DEMAND: Using StrengthsFinder assessment results to pair students up for more successful and meaningful group work
Creators: name: Vlaun, Kristen
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: During the first week of class, I assign students the StrengthsFinder assessment in order to determine their top 5 strengths. The first assignment in our class, is an introductory video during which each student introduces themselves and shares what their top 5 strengths are based on their StrengthsFinder assessment results. The second part of this assignment requires students to respond via board post to another student’s introductory video. The purpose of the board post assignment is to for students to find a peer with different strengths than they have. These pairs become partners for the final assignment of the semester. Ultimately, I want to provide an example of how knowing each other’s strengths and working thoughtfully together can provide a more positive and effective group experience.

description: The 2011 Clean Energy Act sought to align Australia's carbon pricing to the 2005 European Union Emission Trading Scheme (EU-ETS) by 2015, but this act was repealed in 2014. We estimate the hypothetical impact of Australia adopting an emissions trading policy in 2005, which corresponds with the establishment of the EU-ETS. We use a synthetic treatment approach that constructs a counterfactual measure of Australian carbon emissions that makes use of the time series properties of pre-2005 and post-2005 emissions in European countries. We find that Australian per-capita carbon emissions would have been lower by about 4.5% as a result of the policy -- a result that is robust to several variations of our methodology.
Superposition of ferromagnetic and antiferromagnetic spin chains in the quantum magnet BaAg2Cu[VO4]2

description: Based on density functional theory band structure calculations, quantum Monte-Carlo simulations, and high-field magnetization measurements, we address the microscopic magnetic model of BaAg2Cu[VO4]2 that was recently proposed as a spin-1/2 anisotropic triangular lattice system. We show that the actual physics of this compound is determined by a peculiar superposition of ferromagnetic and antiferromagnetic uniform spin chains with nearest-neighbor exchange couplings of Ja(1) ~ -19 K and Ja(2) ~ 9.5 K, respectively. The two chains featuring different types of the magnetic exchange perfectly mimic the specific heat of a triangular spin lattice, while leaving a clear imprint on the magnetization curve that is incompatible with the triangular-lattice model. Both ferromagnetic and antiferromagnetic spin chains run along the crystallographic 'a' direction, and slightly differ in the mutual arrangement of the magnetic CuO4 plaquettes and non-magnetic VO4 tetrahedra. These subtle structural details are, therefore, crucial for the ferromagnetic or antiferromagnetic nature of the exchange couplings, and put forward the importance of comprehensive microscopic modeling for a proper understanding of quantum spin systems in transition-metal compounds.

description: We study the spin response of cold dense neutron matter in the limit of zero momentum transfer, and show that the frequency dependence of the long-wavelength spin response is well constrained by sum-rules and the asymptotic behavior of the two-particle response at high frequency. The sum-rules are calculated using Auxiliary Field Diffusion Monte Carlo technique and the high frequency two-particle response is calculated for several nucleon-nucleon potentials. At nuclear saturation density, the sum-rules suggest that the strength of the spin response peaks at $ω\simeq$ 40--60 MeV, decays rapidly for $ω\geq $100 MeV, and has a sizable strength below 40 MeV. This strength at relatively low energy may lead to enhanced neutrino production rates in dense neutron-rich matter at temperatures of relevance to core-collapse supernova.

Informing and supporting climate change adaptation in British Columbia’s forests through monitoring
Creators: name: Eddington, Margaret Maree
Publisher: name: University of British Columbia
Year: 2014

description: Given the large uncertainties associated with climate change, regular and systematic measurement of various aspects of the natural environment is the primary means for understanding what changes are actually taking place. This research is focused on the development of a strategy for monitoring the biophysical attributes of British Columbia’s forest and rangelands in order to supply the information needed to bring climate change adaptation considerations into decision-making in the Province. A framework of indicators for monitoring the impacts of climate change was developed through iterative, bottom-up processes involving both expert and end-user participation. The former involved interviews with key experts and an indicator development workshop attended by 58 delegates from across the Province. The latter involved a web-based survey designed to better identify the indicator framework’s target audience as well as their key information needs and management questions with regard to climate change adaptation. The resultant framework identifies seventeen indicators of varying importance for monitoring in light of climate change. I developed approaches to measuring some of the indicators and analyzed the capacity of current monitoring and inventory programs to support their evaluation. Where possible, the data available to support the indicators was tested in south eastern British Columbia. This was designed to assess the capacity of the existing data sources to meet decision makers’ climate change adaptation needs. The results of these tests showed that, while there are some relatively good data sources that can be used to support climate change adaptation in forests and rangelands, there are some indicators for which there is a paucity of data. Through this research I have been successful in developing a solid foundation for increasing the information available to incorporate climate change adaptation considerations into British Columbia’s forest and range management. My research also offers an example to other sectors, countries and regions who are seeking to use their data to track climate change and better understand its impacts.
Estimation in functional linear quantile regression

description: This paper studies estimation in functional linear quantile regression in which the dependent variable is scalar while the covariate is a function, and the conditional quantile for each fixed quantile index is modeled as a linear functional of the covariate. Here we suppose that covariates are discretely observed and sampling points may differ across subjects, where the number of measurements per subject increases as the sample size. Also, we allow the quantile index to vary over a given subset of the open unit interval, so the slope function is a function of two variables: (typically) time and quantile index. Likewise, the conditional quantile function is a function of the quantile index and the covariate. We consider an estimator for the slope function based on the principal component basis. An estimator for the conditional quantile function is obtained by a plug-in method. Since the so-constructed plug-in estimator not necessarily satisfies the monotonicity constraint with respect to the quantile index, we also consider a class of monotonized estimators for the conditional quantile function. We establish rates of convergence for these estimators under suitable norms, showing that these rates are optimal in a minimax sense under some smoothness assumptions on the covariance kernel of the covariate and the slope function. Empirical choice of the cutoff level is studied by using simulations.

power applications has been used to build two Dielectric
Resonator Oscillators. Despite this technology addresses the
mobile telephony frequency range at 1.8GHz, the oscillators
generate a stable reference at 6GHz and 7.5GHz with good
phase noise performance. A low frequency noise model has
been identified and implemented in a Gummel Poon BJT
nonlinear model. A design technique to optimize stability
and phase noise performances has been used. The DROs
exhibit phase noise of -116dBc/Hz and -107dBc/Hz at 10KHz
offset from the carrier at 6GHz and 7.5GHz, respectively.

description: Ziel der Arbeit war es den Einfluss von Tumor infiltrierenden regulatorischen T-Zellen (Treg) auf die Prognose von Pankreaskarzinompatienten zu überprüfen. Hierfür wurden primär resezierte Pankreaskarzinome immunhistochemisch mit einer Färbung gegen den für Treg spezifischen Transkriptionsfaktor FOXP3 ausgewertet. Ein umfangreiches Follow-up dokumentierte den postoperativen Krankheitsverlauf der untersuchten Patienten. Für die endgültige Auswertung lagen Daten von 79 Patienten vor. Eine hohe Infiltrationsdichte im invasiven Grenzbereich des Tumors zeigte sich mit einer signifikant häufigeren Lymphknoteninfiltration und schlechteren Differenzierung verbunden. Das Gesamtüberleben der Patienten war signifikant länger, wenn die Fraktion der intratumoral gegenüber den peritumoral lokalisierten Treg niedrig war. Patienten die im weiteren Krankheitsverlauf Lebermetastasen entwickelten wiesen tendenziell eine höhere Treg-Dichte auf als dies bei isolierten Lokalrezidiven der Fall war. Mit der Arbeit konnte gezeigt werden, dass die Anzahl der regulatorischen T-Zellen im Tumor mit der Prognose des Pankreaskarzinoms assoziiert ist und diese möglicherweise kausal beeinflusst.

description: Over the past year, students and instructors have faced unprecedented challenges related to the global pandemic, political unrest, and natural disasters—many of which are rooted in long histories of injustice that will continue to raise challenges for the foreseeable future. Moreover, even in the best of times students and instructors regularly face personal challenges that are just as stressful as those that are publicly shared. Such circumstances call for pedagogical practices that are compassionate towards both instructors and students, yet still compatible with holding ourselves and our students accountable to high standards of inclusive excellence. In this panel discussion, we will share our own journeys towards compassion and accountability, solicit participants’ experiences, and brainstorm together how best to achieve both going forward. Participants will leave with a comprehensive list of compassionate practices to consider, in-depth understanding of accountability concerns and how they might be creatively addressed, a department-level model of instructor peer support, and individualized peer feedback on the specific practices they are considering integrating into their pedagogy.

description: This paper presents a new methodology
based on actively coupled resonators, for achieving
microwave active filters. In this method, which lends itself
to narrowband and wideband filtering applications, we
associate core cells with different resonance frequencies,
adjusted separately, to synthesise a Butterworth, Chebyshev
or other all-pole approximation. Two 1-pole bandpass filters
centred at 9GHz, with 3dB bandwidth of 500 MHz, high
gain of 17 dB and 21 dB, including a very low-noise active
filter which exhibits a noise figure of 1.7 dB are realised in a
first part. A 3-pole bandpass filter centred at 12GHz is also
presented to validate this method, it has a gain of 15.5 dB ±
0.2 over a 1.5 GHz bandwidth and rejections better than 60
dB at 7 GHz and 18 GHz.

description: Das Plasmamembranproteom ist hochdynamisch und spielt eine entscheidende Rolle in vielen biologischen Prozessen, wodurch dieses Subproteom ein prominentes Ziel für pharmazeutische Eingriffe ist. Darüber hinaus gibt es immer mehr Hinweise auf aktive Mechanismen für die Ein- und Ausschleusung von Wirkstoffen durch membrangebundene Transporter. Daher kann die Expression dieser Proteine die Wirkung von Wirkstoffen beeinflussen und zu Arzneimittelresistenz führen. Ein detailliertes Verständnis der Zusammensetzung des Oberflachenproteoms und dessen Dynamik kann somit einen großen Einfluss auf die Arzneimittelforschung haben. Die Analyse von Zelloberflächenproteinen ist jedoch aufgrund ihrer biochemischen Eigenschaften und ihrer geringen Mengen eine Herausforderung. In dieser Arbeit wurde ein sensitives und selektives Protokoll für die umfassende Identifizierung und Quantifizierung von Zelloberflächenproteinen mittels Massenspektrometrie etabliert. Weiterhin wurde dieses Protokoll mit dem kürzlich beschriebenen Thermal Proteome Profiling (Savitski 2014) kombiniert, um Wirkstoffbindungen an Membranproteinen auf lebenden Zellen zu analysieren.
description: The plasma membrane proteome is highly dynamic and has crucial roles in many biological processes rendering this subproteome a prominent target for pharmaceutical intervention. Furthermore, there is growing evidence for active drug in- and efflux mechanisms by membrane-bound transporters. Thus, expression of these proteins affects drug-target engagement and can lead to drug resistance. A detailed understanding of the plasma membrane proteome composition and its dynamics can have a significant impact on drug discovery. However, analysis of the cell surface proteome is challenging due to its biochemical properties and low abundance. Here, a sensitive and selective enrichment protocol was established for the comprehensive identification and quantification of cell surface accessible proteins by mass spectrometry. In addition, we combined the recently described thermal proteome profiling (Savitski 2014) enabling target identification and determination of target engagement with our protocol to specifically monitor drug binding to cell surface presented membrane proteins on live cells.
Photonic spin control for solar wind electric sail

description: The electric solar wind sail (E-sail) is a novel, efficient propellantless propulsion concept which utilises the natural solar wind for spacecraft propulsion with the help of long centrifugally stretched charged tethers. The E-sail requires auxiliary propulsion applied to the tips of the main tethers for creating the initial angular momentum and possibly for modifying the spinrate later during flight to counteract the orbital Coriolis effect and possibly for mission specific reasons. We introduce the possibility of implementing the required auxiliary propulsion by small photonic blades (small radiation pressure solar sails). The blades would be stretched centrifugally. We look into two concepts, one with and one without auxiliary tethers. The use of photonic blades has the benefit of providing sufficient spin modification capability for any E-sail mission while keeping the technology fully propellantless. We conclude that the photonic blades appear to be a feasible and attractive solution to E-sail spinrate control.

Balance simulations is used in this paper for the definition

standard design goals on third or fifth order
intermodulation products, usually involving timeconsuming
two-tone HB analyses, are more simply but with
sufficient accuracy taken into account by means of faster
single-tone HB analyses in the iterative design process. The
proposed procedure is compared with standard approaches
in the design case of single-transistor and multiple
paralleled-transistors MMIC amplifiers, showing dramatic
reductions in computation time.

description: Describing the COVID–19 pandemic as the “new normal” trivializes the challenge for students who suddenly faced the decision either to pause their higher education progress or take their first online course. Choosing to continue their education online meant facing learning in a completely new environment where new levels of self-motivation to learn were wrapped in social isolation. The situation was coupled with a highly distracted family life and likely the first time that they faced the need to share screen time with family members. Our work uses an online survey created by staff of the Stearns Center Division of Digital Learning to survey the effectiveness of strategies as perceived by online learners. Pre- and post- COVID-19 survey results were used to explore differences between first-time online learners prior to the advent of the pandemic to those who had little choice but to take their first online course. Comparing results from the survey administered in the required introductory Marketing course in Spring 2020 with students taking the same online course in Fall 2020, we can report some of the key aspects of online learning Pre- and Post- COVID–19. The findings inform faculty developing online courses of comparisons related to course navigation, group activities, learning style or adaptability, and the impact on first-time online learners. Key take-aways: -Participants will be able to compare first time learner's online experiences related to the COVID-19 disruption. -Since it is expected that there will be more online classes available going forward, participants can think about the findings of our study in the development of effective learning strategies. -The evidence from the survey suggests ways and best practices that can be applied in the classes to help students be successful.

description: The entanglement quantum properties of a spin-1/2 Ising-Heisenberg model on a symmetrical diamond chain were analyzed. Due to the separable nature of the Ising-type exchange interactions between neighboring Heisenberg dimers, calculation of the entanglement can be performed exactly for each individual dimer. Pairwise thermal entanglement was studied in terms of the isotropic Ising-Heisenberg model, and analytical expressions for the concurrence (as a measure of bipartite entanglement) were obtained. The effects of external magnetic field $H$ and next-nearest neighbor interaction $J_m$ between nodal Ising sites were considered. The ground-state structure and entanglement properties of the system were studied in a wide range of the coupling constant values. Various regimes with different values of the ground-state entanglement were revealed, depending on the relation between competing interaction strengths. Finally, some novel effects, such as the two-peak behavior of concurrence versus temperature and coexistence of phases with different values of magnetic entanglement were observed.

description: VR technologies are gaining momentum in the field of education and particularly in the use of Virtual Reality (VR) based learning. Within Virtual Reality Environments (VREs) realistic- world situations are simulated, facilitating the transfer of the knowledge and skills gained within the virtual world to the real one. In this chapter we provide a review of several advantages of using VR technology in education and training. In addition, we examine different challenges and potential problems that need to be considered in order to successfully integrate VR in training activities. We also exemplify the promising prospect of this technology in education by describing two novel VR applications. The first one aim to support educators in improving their teaching practice. Using VR technology, the teacher is given the opportunity to experience the students point of view during a classic room and cultivate their empathy skills. The second one aims to support teachers in creating VR serious games by lowering the difficulty of developing this type of educational artefact through intuitive interaction and eliminating the need of learning new design language.

technology is presented with which devices with figures of
1600mS/mm for DC transconductance and 430GHz for
cutoff frequency fT have been realised. This performance
can be attributed to the use of a non-annealed/non-alloyed
ohmic contact process which acts to reduce parasitic access
resistances to the device. To the best of our knowledge, hese
performance figures are the highest reported to date for a
HEMT device fabricated from a lattice-matched InP
material system.

description: Large parasitic series resistances of
heterojunction bipolar transistor (HBT) are shown to cause
a sharp kink in the base current (IB) of the Gummel plot at
elevated temperatures under high collector currents (IC) and
low base-collector (b-c) applied bias (VBC). This effect was
analyzed and attributed to the temperature dependence of
low-field and high field mobilities of undepleted and
depleted areas at the b-c region. Using this observed kink a
simple technique is presented to extract terminal resistances
variation with temperature for an InGaP/GaAs DHBT.
These extracted values are compared and verified with
those extracted from s-parameter measurements. By
incorporating these values into a temperature-dependent
large signal DHBT model more accurate thermal behavior
of IB at high current is demonstrated.

This can hinder their ability to develop effective process management skills, necessary for planning and executing multi-step tasks in a project-based learning model. This hyperlinked, digital poster illustrates the timeline of major projects throughout the semester, and identifies and connects the various skill-building activities/assignments leading up to each. As you navigate through the links, you can explore a variety of resources, group activities and discussions that help build critical reading, rhetorical analysis and synthesis skills required for projects in ENGH 302 - Advanced Composition. This timeline can be used as an interactive reference guide for your students, as they can quickly revisit specific skill-building activities as needed throughout the term. This timeline could effectively be tailored to fit any course, across disciplines.

description: A comprehensive modelling approach is applied
to the study of power pHEMT devices for high efficiency
microwave and millimetre-wave power amplifier
applications. The association of electromagnetic, physical
and non-linear simulations has been applied for the first
time to the design of high power microwave amplifiers. This
research has provided insight into the operation of large
transistors, allowing the contribution of individual FET
fingers and cells to be investigated. This work has already
demonstrated how the transistor structure contributes to
the RF performance and enables the design of the transistor
and embedding circuit to be optimised.
ON DEMAND: Strategies to Support Transfer Students in Asynchronous Classrooms
Creators: name: Grieco, Christina
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: Undergraduate transfer students face unique challenges when moving between institutions, and the sudden shift from in-person to virtual learning during the COVID-19 pandemic created additional barriers for them. Due to the transition, transfer students did not have many opportunities to engage face-to-face and feel connected to the Mason community, and this may continue in the future as students opt to take more classes online. Faculty play a critical role in helping transfer students successfully navigate and connect to their new institution, and this can be an especially difficult task in a virtual setting. This poster is intended to inform instructors how to facilitate transfer student learning experiences in online, asynchronous classrooms by using strategies such as creating an orientation module and providing a “quick guide” to student support services. Additionally, this poster will provide approaches to establishing a sense of community between transfer students and their peers in asynchronous courses in the current academic climate and beyond.

description: This paper demonstrates a small compact 5.7
GHz upconversion Gilbert micromixer using 0.35  m SiGe
HBT technology. A micromixer has a broadband matched
single-ended input port. A passive LC current combiner is
used to convert micromixer differential output into a singleended output and doubles the output current for singleended-input and single-ended-output applications. Thus, a truly balanced operation of a Gilbert upconversion mixer with a single-ended input and a single-ended output is
achieved in this paper. The fully matched upconversion
micromixer has conversion gain of –4 dB, OP1dB of –9.5 dBm
and OIP3 of –1.5 dBm when input IF=0.3 GHz, LO=5.4 GHz
and output RF=5.7 GHz. The IF input return loss is better
than 18 dB for frequencies up to 20 GHz while RF output
return loss is 25 dB at 5.7GHz. The supply voltage is 3.3V
and the current consumption is 4.6 mA. The die size is 0.9 
0.9 mm2with 3 integrated on-chip inductors.

description: No abstracts are to be cited without prior reference to the author.Since 1986, physico-chemical and chlorophyll 'a' data are obtained by means of CTD profiles and bottle samples at an offshore station located in the southeastern Bay of Biscay (43º 27’ N, 1º 55’ W). The station is considered to be non-impacted by anthropogenic influence due to its distance (13.1 km) from the main pollution sources in land, which makes it suitable for exploring the response of phytoplankton to oceanometeorological forcing.

description: The First World War devastated the human workforce through death and invalidity and caused a massive destruction of infrastructure and material in South East Europe. Its economies underwent a major setback from an already unfavorable situation. In addition, Romania and Yugoslavia faced huge problems in the processes of economic integration, resulting in misunderstanding and confusion. Post-war agrarian reforms carried out in all South East European countries had all the characteristics of land redistribution but did not have any plans to enhance the economic efficiency of the agricultural sector.

Subjects: ING-INF/01 Elettronica

description: Although mixer design is often viewed as a mature technology, there seems to be no end to the supply of creative new ideas for mixer circuits, or for new needs. Today, the needs of system designers are evolving from high-performance circuits to low-cost, manufacturable, and integrable designs. This particularly true of mixers for wireless, cellular, and other modern communication systems. In this paper we review the work in this area and examine some of the directions it can—and perhaps should—take.
One-dimensional hydrogen atom with minimal length uncertainty and maximal momentum

description: We present exact energy eigenvalues and eigenfunctions of the one-dimensional hydrogen atom in the framework of the Generalized (Gravitational) Uncertainty Principle (GUP). This form of GUP is consistent with various theories of quantum gravity such as string theory, loop quantum gravity, black-hole physics, and doubly special relativity and implies a minimal length uncertainty and a maximal momentum. We show that the quantized energy spectrum exactly agrees with the semiclassical results.

description: We study the formation of galaxy clusters in the presence of thawing class of scalar field dark energy. We consider cases where the scalar field has canonical as well non canonical kinetic term in its action. We also consider various form for the potential of the scalar field e.g, linear, quadratic, inverse quadratic, exponential as well as Pseudo-Nambu-Goldstone Boson (PNGB) type. Moreover we investigate situation where dark energy is homogeneous as well as the situation where dark energy takes part in virialization process. We use the Sheth-Tormen formalism while calculating the number density of galaxy clusters. Our results show that cluster number density for different dark energy models have significant deviation from the corresponding value for the $Λ$CDM case. The deviation is more for higher redshifts. Moreover the tachyon type scalar field with linear potential has the highest deviation from the $Λ$CDM case. For the total cluster number counts, different dark energy models can have substantial deviation from $Λ$CDM and this deviation is most significant around $z \sim 0.5$ for all the models we considered. We also constrain thawing class of models using the presently available data for number counts of massive X-ray clusters. The results show that current cluster data is not suitable enough for constraining potentials for the thawing scalar fields as well as for other cosmological parameters like $n_{s}$. But one can get significant constraint for the parameter $σ_{8}$ and a lower bound on $Ω_{m0}$.
