description: In the same vein, we find transgression in what is perhaps an unlikely place; the classroom and educational practices. Two articles emphasize the need for transgression in education. The first, Camille Alexander's Teaching Against the Tide suggests that transgressing a canonical syllabus becomes a way of creating a contact zone between students and professors, thereby increasing students' learning and engagement in classes.

description: In multi-band metals quasi-particles arising from different atomic orbitals coexist at a common Fermi surface. Superconductivity in these materials may appear due to interactions within a band (intra-band) or among the distinct metallic bands (inter-band). Here we consider the suppression of superconductivity in the intra-band case due to hybridization. The fluctuations at the superconducting quantum critical point (SQCP) are obtained calculating the response of the system to a fictitious space and time dependent field, which couples to the superconducting order parameter. The appearance of superconductivity is related to the divergence of a generalized susceptibility. For a single band superconductor this coincides with the \textit{Thouless criterion}. For fixed chemical potential and large hybridization, the superconducting state has many features in common with breached pair superconductivity with unpaired electrons at the Fermi surface. The T=0 phase transition from the superconductor to the normal state is in the universality class of the density-driven Bose-Einstein condensation. For fixed number of particles and in the strong coupling limit, the system still has an instability to the normal sate with increasing hybridization.

Resuscitation-promoting factor (Rpf) terminates dormancy among diverse soil bacteria
Creators: name: Lennon, Jay T.
Publisher: name: Zenodo

Subjects: subject: Microbiology
subject: FOS: Biological sciences

description: Microorganisms often inhabit environments that are suboptimal for growth and reproduction. To survive when challenged by such conditions, individuals may engage in dormancy where they enter a metabolically inactive state. For this persistence strategy to confer an evolutionary advantage, microorganisms must be able to resuscitate and reproduce when conditions improve. Among bacteria in the phylum Actinomycetota, dormancy can be terminated by resuscitation-promoting factor (Rpf), an exoenzyme that hydrolyzes glycosidic bonds in the peptidoglycan of the cell wall. We characterized Rpf from Micrococcus KBS0714, a bacterium isolated from agricultural soil. Compared to previous studies, the Rpf elicited activity at relatively high concentrations, yet demonstrated high substrate affinity. Site-directed mutations at conserved catalytic sites significantly reduced or abolished resuscitation, as did the deletion of repeating motifs in a lectin-encoding linker region. We then tested the effects of recombinant Rpf from Micrococcus KBS0714 on a diverse set of dormant soil bacteria. Patterns of resuscitation mapped onto strain phylogeny, which reflected core features of the cell envelope. Additionally, the direction and magnitude of the Rpf effect were associated with functional traits, in particular, aspects of the moisture niche and biofilm production, which are critical for understanding persistence and resuscitation during dormancy. These findings expand our understanding of how Rpf may affect seed-bank dynamics and have implications for the diversity and functioning of soil ecosystems.
Investigating second harmonic generation in collagen tissues
Creators: name: Shen, Mengzhe
Publisher: name: University of British Columbia
Year: 2015

description: Collagen is the most abundant structural protein in the human body. When it is excited by femtosecond near infrared laser, second harmonic generation (SHG) signal at half the wavelength of the excitation wave is excited. For imaging thick tissues, the SHG signal is collected in the backward direction. The objective of this work is to elaborate the origin of the backward SHG in collagen at the fibril level and investigate some of its optic characteristics. The optic characteristics investigated include the wavelength dependence of SHG intensity, which is useful to analyze SHG in collagen tissues. However, the current published results are inconsistent. We study the microscopy system factors affecting the wavelength dependence and calibrate them by measuring the wavelength dependence of SHG intensity in a BaB₂O₄ crystal. With the proper calibration, typical wavelength dependence SHG spectra from mouse tail and Achilles tendon are investigated. The backward-collected SHG signal includes the backward generated SHG, and the forward generated but backward scattered SHG. Those two sources of the total backward SHG have different properties due to the difference in phase mismatch in the forward and backward directions. Here a non-invasive method is developed to separate them by using pinholes. By varying the pinhole size in a confocal multiphoton microscopy, the proportion of the backward scattered SHG to the total backward SHG can be obtained. Our results indicate that backward scattered SHG may not be the major source of backward SHG in the mouse tail tendon, which means significant SHG is purely generated in the backward direction. A large phase mismatch exists in generating backward SHG. Nevertheless, significant backward generated SHG has been observed in collagen tissues. We hypothesize that the periodic lattice structure of fibrillar collagen can provide a virtual momentum to assist the backward phase matching. Here the backward SHG phase matching is investigated in theory, simulation, and experiments, which are consistent and support the hypothesis. The various properties investigated in this thesis can provide a better understanding about SHG in collagen tissues and lead to new applications of SHG microscopy in diagnosing collagen related diseases in the future.

description: This paper presents an analytical study of the coexistence of different transport regimes in quasi-one-dimensional surface-disordered waveguides (or electron conductors). To elucidate main features of surface scattering, the case of two open modes (channels) is considered in great detail. Main attention is paid to the transmission in dependence on various parameters of the model with two types of rough-surface profiles (symmetric and antisymmetric). It is shown that depending on the symmetry, basic mechanisms of scattering can be either enhanced or suppressed. As a consequence, different transport regimes can be realized. Specifically, in the waveguide with symmetric rough boundaries, there are ballistic, localized and coexistence transport regimes. In the waveguide with antisymmetric roughness of lateral walls, another regime of the diffusive transport can arise. Our study allows to reveal the role of the so-called square-gradient scattering which is typically neglected in literature, however, can give a strong impact to the transmission.

Media as a social institution : the power dynamics of media in the young adult dystopian fiction of M.T. Anderson and Suzanne Collins
Creators: name: Baker, Kaline Elizabeth
Publisher: name: University of British Columbia
Year: 2015

description: Using a wide array of research on media and youth, combined with theories about dystopian literature, this thesis examines the portrayal of media in the young adult novels Feed, by M.T. Anderson, and the Hunger Games trilogy by Suzanne Collins. This research study is a part of the larger critical discussion about how adult anxieties concerning media use by youth manifest themselves in the fiction written for adolescents by adult authors. By examining the concepts of surveillance, discipline, punishment, and resistance through the critical lens of Michel Foucault’s theories in his work Discipline and Punish, as well as the work of Roberta Trites in Disturbing the Universe, this study finds that media is classified as a social institution in Anderson’s and Collins’ young adult dystopian narratives. In these novels, the dystopian regimes utilize media to maintain social order and behavior. This study explores how the young adult protagonists are disempowered by media, learn how media as a social force controls their lives, and gain agency through a reversal of media use to reinforce their personal power and independence.

Unveiling the spatial structure of the overionized plasma in the supernova remnant W49B

description: W49B is a mixed-morphology supernova remnant with thermal X-ray emission dominated by the ejecta. In this remnant, the presence of overionized plasma has been directly established, with information about its spatial structure. However, the physical origin of the overionized plasma in W49B has not yet been understood. We investigate this intriguing issue through a 2D hydrodynamic model that takes into account, for the first time, the mixing of ejecta with the inhomogeneous circumstellar and interstellar medium, the thermal conduction, the radiative losses from optically thin plasma, and the deviations from equilibrium of ionization induced by plasma dynamics. The model was set up on the basis of the observational results. We found that the thermal conduction plays an important role in the evolution of W49B, in- ducing the evaporation of the circumstellar ring-like cloud (whose presence has been deduced from previous observations) that mingles with the surrounding hot medium, cooling down the shocked plasma, and pushes the ejecta backwards to the center of the remnant, forming there a jet-like structure. During the evolution, a large region of overionized plasma forms within the remnant. The overionized plasma originates from the rapid cooling of the hot plasma originally heated by the shock reflected from the dense ring-like cloud. In particular, we found two different ways for the rapid cooling of plasma to appear: i) the mixing of relatively cold and dense material evaporated from the ring with the hot shocked plasma and ii) the rapid adiabatic expansion of the ejecta. The spatial distribution of the radiative recombination continuum predicted by the numerical model is in good agreement with that observed.

Publisher: name: Old Dominion University Libraries
Year: 2021

description: The DoD is currently taking a supply-chain risk management strategy to foster cybersecurity. This unique strategy is often referred to as CMMC which stands for “Cybersecurity Maturity Model Certification”. The approach requires that all the 300,000 DoD contractors acquire third-party authentication that may attain the requirements for the CMMC maturity level suitable to the work they desire to do for the DoD. CMMC typically examines the organization's capability to safeguard Federal Contract Information as well as CUI. It integrates various cybersecurity standards already in place and plots the best practices alongside processes to five maturity levels that range from the fundamental cyber hygiene practices at level 1 to highly advanced practices at level 5.

School Based Management in Bedouin Schools in Israel
Creators: name: MIzel, Omar
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: School-Based Management (SBM) schools enjoy flexibility in resource utilisation and their success largely depends on their context's directives and characteristics. In 1995, Israel's Education Ministry transferred nine Jewish schools to SBM. Three years later, the ministry instructed the five Bedouin schools in Rahat to become SBM. The Bedouins are the first Israeli minority to adopt SBM in their schools. This research study will describe, study and assess the extent of SBM's implementation in the five Rahat schools, discussing the unique context, which studies on this subject have so far excluded. The context is unique because it is complex: the political relationship between majority (Jews) and minority (Arabs), the confrontation between a traditional, conservative society (Bedouin) and a modem, continually changing one (Israeli), and the Arab school system's total separation from the Jewish one. The study's target population consisted of the five coeducational primary schools' 179 teachers and five principals. Two approaches were used to analyse the findings: positivist-quantitative and phenomenological-qualitative, and two different tools to assess SBM in the five schools. The first tool, a questionnaire, was sent to the teachers and principals, who graded answers 1 to 5, while the second was a semi-structured interview with the five principals and with randomly selected 20 teachers (four from each school).The results of SBM's pilot application in Israel's Bedouin community were opposite to what the Ministry of Education anticipated. The main factors that prevented the five schools from implementing SBM and increased centralisation included extensive intervention in school affairs by the Education Ministry and the local tribe, especially its leader (sheikh), and Bedouin society's conservativism. Instead of implementing SBM, Bedouin schools should improve teacher training, upgrade the physical infrastructure, neutralise tribal influence, and use innovative teaching methods.
Phantom energy accretion and primordial black holes evolution in Brans-Dicke theory

description: In this work, we study the evolution of primordial black holes within the context of Brans-Dicke theory by considering the presence of a dark energy component with a super-negative equation of state called phantom energy as a background. Besides Hawking evaporation, here we consider two type of accretions - radiation accretion and phantom energy accretion. We found that radiation accretion increases the lifetime of primordial black holes whereas phantom accretion decreases the lifespan of primordial black holes. Investigating the competition between the radiation accretion and phantom accretion, we got that there is an instant during the matter-dominated era beyond which phantom accretion dominates radiation accretion. So the primordial black holes which are formed in the later part of radiation dominated era and in matter dominated era are evaporated at a quicker rate than the Hawking evaporation. But for presently evaporating primordial black holes, radiation accretion and Hawking evaporation terms are dominant over phantom accretion term and hence presently evaporating primordial black holes are not much affected by phantom accretion.

description: Using the derived gamma-ray burst E_peak and fluences from the complete BATSE 5B Spectral Catalog, we study the ensemble characteristics of the E_peak-fluence relation for GRBs. This relation appears to be a physically meaningful and insightful fundamental discriminator between long and short bursts. We discuss the results of the lower limit test of the E_peak-E_iso relations in the E_peak-fluence plane for BATSE bursts with no observed redshift. Our results confirm the presence of two GRB classes as well as heavily suggesting two different GRB progenitor types.

Precipitation and recrystallization in a binary magnesium-neodymium alloy
Creators: name: Sterling, Elizabeth
Publisher: name: University of British Columbia
Year: 2015

description: The influence of precipitate state and annealing temperature on the recrystallization of a Mg-2.8wt.%Nd alloy has been investigated. Precipitation kinetics at 190°C, 350°C and 400°C were studied in order to understand precipitate evolution during recrystallization. Precipitation was studied primarily through electrical resistivity measurements, and modelled using a mean radius model. It was found that predicting the kinetics required the spatial distribution of solute to be considered. Pre-aging conditions were selected in order to study the influence of either pre-existing or concurrently formed precipitates during recrystallization. After aging, the samples were cold rolled to a strain of 20%. The microstructures were characterized primarily through EBSD, and also through hardness measurements. Pre-aging the samples at 400°C for three hours resulted in a dispersion of stable β precipitates during annealing. This led to a recrystallized microstructure with recrystallization nucleation sites similar to those previously reported in the literature. Pre-aging the sample at 190°C for 24 hours lead to the formation of metastable β'' precipitates which strengthened the sample, but dissolved rapidly upon annealing at higher recrystallization temperatures. When samples previously solutionized at 545°C or aged at 190°C were subsequently annealed at 350°C, recrystallization stagnated. This was attributed to concurrent precipitation pinning grain boundaries. In all samples, irrespective of aging condition, recrystallization was observed primarily in twins and shear bands. The twins which recrystallized were found to be {10-11} contraction twins and {10-11}{10-12} contraction-extension twins. As the nuclei forming within these regions were not randomly oriented, recrystallization in these alloys did not randomize the texture. The work presented in this thesis increases understanding of recrystallization in Mg-Nd alloys. In particular, the means by which Nd interacts with and affects the recrystallizing microstructure have never been studied in detail. Furthermore, this work points to possible ways in which new magnesium alloys and thermomechanical processes could be designed to improve final material properties.

The general trends for the binding energies for super-heavy nuclei are significantly different for these models. The SHF models tend to underbind the superheavy nuclei, while, RMF models show just the opposite trend.

description: Two aspects of TDDFT, the linear response approach and the adiabatic local density approximation, are examined from the perspective of lattice models. To this end, we review the DFT formulations on the lattice and give a concise presentation of the time-dependent Kadanoff-Baym equations, used to asses the limitations of the adiabatic approximation in TDDFT. We present results for the density response function of the 3D homogeneous Hubbard model, and point out a drawback of the linear response scheme based on the linearized Sham-Schlüter equation. We then suggest a prescription on how to amend it. Finally, we analyze the time evolution of the density in a small cubic cluster, and compare exact, adiabatic-TDDFT and Kadanoff-Baym-Equations densities. Our results show that non-perturbative (in the interaction) adiabatic potentials can perform quite well for slow perturbations but that, for faster external fields, memory effects, as already present in simple many-body approximations, are clearly required.

Concatenation of Error Avoiding with Error Correcting Quantum Codes for Correlated Noise Models

Year: 2010

description: We study the performance of simple error correcting and error avoiding quantum codes together with their concatenation for correlated noise models. Specifically, we consider two error models: i) a bit-flip (phase-flip) noisy Markovian memory channel (model I); ii) a memory channel defined as a memory degree dependent linear combination of memoryless channels with Kraus decompositions expressed solely in terms of tensor products of X-Pauli (Z-Pauli) operators (model II). The performance of both the three-qubit bit flip (phase flip) and the error avoiding codes suitable for the considered error models is quantified in terms of the entanglement fidelity. We explicitly show that while none of the two codes is effective in the extreme limit when the other is, the three-qubit bit flip (phase flip) code still works for high enough correlations in the errors, whereas the error avoiding code does not work for small correlations. Finally, we consider the concatenation of such codes for both error models and show that it is particularly advantageous for model II in the regime of partial correlations.

From proper motions to star cluster dynamics: measuring velocity dispersion in deconvolved distribution functions

description: We investigate the effect that the usually large errors associated with ground-based proper motion (PM) components have on the determination of a star cluster's velocity dispersion (\sv). Rather than histograms, we work with PM distribution functions (PMDFs), taking the $1σ$ uncertainties formally into account. In this context, a cluster's intrinsic PMDF is broadened by the error distribution function (eDF) that, given the average error amplitude, has a width usually comparable to the cluster PMDF. Thus, we apply a Richardson-Lucy (RL) deconvolution to the PMDFs of a set of relatively nearby and populous open clusters (OCs), using the eDFs as point spread functions (PSFs). The OCs are NGC\,1039 (M\,34), NGC\,2477, NGC\,2516, NGC\,2682 (M\,67), and NGC\,7762. The deconvolved PMDFs are approximately Gaussian in shape, with dispersions lower than the observed ones by a factor of 4-10. NGC\,1039 and NGC\,2516, the nearest OCs of the sample, have deconvolved \sv\ compatible with those of bound OCs of mass $\sim10^3$\,\ms. NGC\,2477 and NGC\,2682 have deconvolved PMDFs with a secondary bump, shifted towards higher average velocities, which may be an artefact of the RL deconvolution when applied to asymmetric profiles. Alternatively, it may originate from cluster merger, large-scale mass segregation or, least probably, binaries.

Implications of the TTV-Detection of Close-In Terrestrial Planets Around M Stars for Their Origin and Dynamical Evolution

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: It has been shown that an Earth-size planet or a super-Earth, in resonance with a transiting Jupiter-like body in a short-period orbit around an M star, can create detectable TTV signals (Kirste \& Haghighipour, 2011). Given the low masses of M stars and their circumstellar disks, it is expected that such a transiting giant planet to have formed at large distances and migrated to its close-in orbit. That implies, if such systems are discovered around M stars, the terrestrial planet had to form during the migration of the giant planet. The formation of this object may be either in-situ (in a close-in orbit) followed by its capture in resonance, or the object is formed at larger distances where it was subsequently captured in a resonance with the migrating giant planet. We have investigated these two scenarios by simulating the dynamics of a disk of protoplanetary embryos and the formation of terrestrial planets during the migration of a Jupiter-like planet around an M star. Results suggest that unless the migration of the giant planet is very slow (slower than 1E-7 AU/year), it is unlikely that the close-in terrestrial planet is formed in-situ. If a terrestrial planet is detected in a mean-motion resonance with a close-in giant planet around an M star, the terrestrial planet was most likley formed at large distances and carried to its close-in resonant orbit by the migrating giant body.

Development of novel small molecule inhibitor of androgen receptor to treat castration-resistant prostate cancer
Creators: name: Yang, Yu Chi (Kevin)
Publisher: name: University of British Columbia
Year: 2016

description: Androgen receptor (AR), a transcription factor, is a validated therapeutic target for prostate cancer. All current AR-targeting therapies inhibit the growth of prostate cancer cells by blocking the ligand-binding domain (LBD), where androgen binds to activate the receptor. Unfortunately, these therapies fail to maintain a durable clinical effectiveness, as patients eventually succumb to castration-resistant prostate cancer (CRPC). The clinical onset and progression of most CRPC is accompanied by rising levels of serum prostate specific antigen (PSA), a gene transcriptionally regulated by AR. This indicates aberrant AR transcriptional activity is involved in driving CRPC and conferring therapy-resistance. Therefore, it is imperative to continue the research and development of novel AR inhibitors that can overcome molecular mechanisms underlying aberrant AR transcriptional activity. This dissertation presents three research projects: 1) Discovery of novel AR inhibitors; 2) Evaluation of EPI-002, an AR N-terminal domain (NTD) antagonist; and 3) Generation of a prostate cancer cell line model with resistance to EPI-002. To discover novel AR inhibitors, candidate compounds identified from high throughput screening were characterized by fluorescent ligand binding assays, AR-driven reporter assays, qPCR gene expression analyses, and proliferation assays. AR NTD inhibitor EPI-002 was evaluated against several mechanisms believed to cause aberrant AR transcriptional activity, including coactivator overexpression, AR gain-of-function mutations, and constitutively active AR splice variants with truncated LBD. To generate a prostate cancer cell line model that developed resistance to EPI-002, LNCaP human prostate cancer cells were cultured under chronic EPI-002 exposure. First, spongian diterpenoids were discovered as novel antiandrogens that bind to the AR LBD. The diterpenoids blocked androgen-dependent AR transcriptional activity with a structure-activity relationship, reduced androgen-regulated gene expression, and inhibited the proliferation of androgen-sensitive prostate cancer cells. Secondly, EPI-002 was effective against aberrant AR transcriptional activity caused by overexpressed coactivators; AR gain-of-function mutations; and constitutively active AR splice variants such as AR-V7. Importantly, EPI-002 inhibited the growth of CRPC cells driven by AR-V7, whereas antiandrogens had no effect. Finally, a human prostate cancer cell line model resistant to growth inhibition by EPI-002 was generated, allowing future studies to investigate mechanisms of resistance against AR inhibition through the NTD.

description: We explore the properties of weakly bound bosonic states in the strongly interacting regime. Combining a correlated-Gaussian (CG) basis set expansion with a complex scaling method, we extract the energies and structural properties of bosonic cluster states with $N\le6$ for different two-body potentials. The identification of five- and six-body resonances attached to an excited Efimov trimer provides strong support to the premise of Efimov universality in bosonic systems. Our study also reveals a rich structure of bosonic cluster states. Besides the lowest cluster states which behave as bosonic droplets, we identify cluster states weakly bound to one or two atoms forming effective cluster-atom "dimers" and cluster-atom-atom "trimers." The experimental signatures of these cluster states are discussed.

description: The Internet infrastructure is severely stressed. Rapidly growing overheads associated with the primary function of the Internet---routing information packets between any two computers in the world---cause concerns among Internet experts that the existing Internet routing architecture may not sustain even another decade. Here we present a method to map the Internet to a hyperbolic space. Guided with the constructed map, which we release with this paper, Internet routing exhibits scaling properties close to theoretically best possible, thus resolving serious scaling limitations that the Internet faces today. Besides this immediate practical viability, our network mapping method can provide a different perspective on the community structure in complex networks.
Uniform detection of the pre-main sequence population in the 5 embedded clusters related to the H\,II region NGC\,2174 (Sh2-252)

description: We investigate 5 embedded clusters (ECs) and the extended stellar group itself of the prominent H\,II region NGC\,2174 (Sh2-252), which presents scarce and heterogeneous information, coming from the optical and infrared. Considering the discrepant values of distance and age, the clusters and the H\,II region appear to be physically unrelated. The analysis is based on field-star decontaminated 2MASS photometry, which allows sampling the pre-main sequence (PMS). We find that Sh2-252A, C, E, NGC\,2175s, and Teu\,136 are small ECs (radius within $1.0 - 2.3$\,pc) characterised by a similar age ($\sim5$\,Myr), reddening ($\aV\sim1$), distance from the Sun ($\ds\sim1.4$\,kpc), and low mass ($60-200\,\ms$). This age is consistent with the H\,II region, the presence of O and B stars still in the MS, and the dominance ($\ga95%$ in number) of PMS stars in colour-magnitude diagrams (CMDs). NGC\,2175 is not a star cluster, but an extended stellar group that encompasses the ECs Sh2-252\,A and C. It contains $\sim36%$ of the member stars (essentially PMS) in the area, with the remaining belonging to the 2 ECs. CMDs of the overall star-forming region and the ECs provide $\ds=1.4\pm0.4$\,kpc for the NGC\,2174 complex, consistent with the value estimated for the physically-related association Gem\,OB1. Our uniform approach shows that NGC\,2174 and its related ECs (except, perhaps, for Teu\,136) are part of a single star-forming complex. CMD similarities among the ECs and the overall region suggest a coeval (to within $\pm5$\,Myr) star-forming event extending for several Myr. At least 4 ECs originated in the event, together with the off-cluster star formation that probably gave rise to the scattered stars of NGC\,2175.

description: In recent years several in-depth investigations of the three Galactic Of?p stars were undertaken. These multiwavelength studies revealed the peculiar properties of these objects (in the X-rays as well as in the optical): magnetic fields, periodic line profile variations, recurrent photometric changes. However, many questions remain unsolved. To clarify some of the properties of the Of?p stars, we have continued their monitoring. A new XMM observation and two new optical datasets were obtained. Additional information for the prototypical Of?p trio has been found. HD108 has now reached its quiescent, minimum-emission state, for the first time in 50--60yrs. The echelle spectra of HD148937 confirm the presence of the 7d variations in the Balmer lines and reveal similar periodic variations (though of lower amplitudes) in the HeI5876 and HeII4686 lines, underlining its similarities with the other two prototypical Of?p stars. The new XMM observation of HD191612 was taken at the same phase in the line modulation cycle but at a different orbital phase as previous data. It clearly shows that the X-ray emission of HD191612 is modulated by the 538d period and not the orbital period of 1542d - it is thus not of colliding-wind origin and the phenomenon responsible for the optical changes appears also at work in the high-energy domain. There are however problems: our MHD simulations of the wind magnetic confinement predict both a harder X-ray flux of a much larger strength than what is observed (the modeled DEM peaks at 30-40MK, whereas the observed one peaks at 2MK) and narrow lines (hot gas moving with velocities of 100--200km/s, whereras the observed FWHM is ~2000km/s).

description: In the era of touchless and remote interactions, virtual input devices have gained significantimportance. This paper presents the development of a Virtual Keyboard and Mouse using Python, enablingusers to interact with their computer through hand gestures and object tracking. The system leveragescomputer vision techniques, primarily using the OpenCV library, and hand tracking models fromMediaPipe to detect hand movements. Gesture recognition allows users to simulate mouse actions such asclicking, scrolling, and dragging, while an on-screen keyboard provides text input functionality. Theimplementation ensures real-time responsiveness and accuracy, enhancing user experience andaccessibility. This project can be beneficial in scenarios where physical input devices are unavailable orimpractical, such as touchless interfaces, assistive technology, and gaming applications.

description: We have carried out a pilot study for the SCUBA-2 'All-Sky' Survey, SASSy, a wide and shallow mapping project at 850 microns, designed to find rare objects, both Galactic and extragalactic. Two distinct sets of exploratory observations were undertaken, and used to test the SASSy approach and data reduction pipeline. The first was a 0.5 by 0.5 degrees map around the nearby galaxy NGC 2559. The galaxy was easily detected at 156 mJy, but no other convincing sources are present in the map. Comparison with other galaxies with similar wavelength coverage indicates that NGC 2559 has relatively warm dust. The second observations cover 1 square degree around the W5-E HII region. As well as diffuse structure in the map, a filtering approach was able to extract 27 compact sources with signal-to-noise greater than 6. By matching with data at other wavelengths we can see that the SCUBA-2 data can be used to discriminate the colder cores. Together these observations show that the SASSy project will be able to meet its original goals of detecting new bright sources which will be ideal for follow-up observations with other facilities.
