description: Deep learning is being used extensively in a variety of software engineering tasks, e.g., program classification and defect prediction. Although the technique eliminates the required process of feature engineering, the construction of source code model significantly affects the performance on those tasks. Most recent works was mainly focused on complementing AST-based source code models by introducing contextual dependencies extracted from CFG. However, all of them pay little attention to the representation of basic blocks, which are the basis of contextual dependencies. In this paper, we integrated AST and CFG and proposed a novel source code model embedded with hierarchical dependencies. Based on that, we also designed a neural network that depends on the graph attention mechanism.Specifically, we introduced the syntactic structural of the basic block, i.e., its corresponding AST, in source code model to provide sufficient information and fill the gap. We have evaluated this model on three practical software engineering tasks and compared it with other state-of-the-art methods. The results show that our model can significantly improve the performance. For example, compared to the best performing baseline, our model reduces the scale of parameters by 50\% and achieves 4\% improvement on accuracy on program classification task.

description: The Family and Music is about the conflict that emerges between Ana María Garcia and Teresa Garcia—Mexican-American teenage sisters living in the Midwest in the 1990s—when one is revealed to be a musical prodigy. Raised by a widowed father, the discovery of the younger sister Teresa’s talent makes her still-grieving father devoted to making her a famous musician. The result, over the years, is the gradual alienation of his older daughter, Ana María, who at the beginning of the novel, enrolls in a new, primarily white upper-middle class high school. Ana María, or Marie (as she fashions herself), tries to have a normal life while contending with a father who devotes his time to her sister, who is single-mindedly in a pursuit of rock music stardom. The third-person narration, taking place between 1996 and 1997, is interwoven with present-day “interviews” with people who look back on when they knew the sisters a generation before. The novel’s central dynamic involves a triangular social relationship of a group where one is favored over another or one feels like an outsider (here it is a family unit). the novel’s thematic issues of cultural assimilation, anxiety, depression, dysfunctional family life, body and weight issues, and aspiration and disappointment. Their primarily white, midwestern surroundings tend to mark the girls as racially different, though their multi-ethnicity (indigenous father, white mother) leaves them in a status of “both and neither”.

description: This work presents a proposal for a wireless sensor network for participatory sensing, with IoT sensing devices developed especially for monitoring and predicting air quality, as alternatives of high cost meteorological stations. The system, called pmSensing, aims to measure particulate material. A validation is done by comparing the data collected by the prototype with data from stations. The comparison shows that the results are close, which can enable low-cost solutions to the problem. The system still presents a predictive analysis using recurrent neural networks, in this case the LSTM-RNN, where the predictions presented high accuracy in relation to the real data.

description: Analyzing protein structure and function and identifying gene expression levels that vary in health and disease can lead to elucidation of disease mechanisms, drug target discovery and identification of underlying biomarkers. To this end, this dissertation focuses on three areas involving drug development and disease comprehension. In the first part, an RNA-Seq based gene signature for the prediction of breast cancer metastasis was identified and validated to be prognostic for risk assessment and patient stratification. After diagnosis, cancer progression and metastasis play critical roles in patient survival, thus identifying the genes that correlate with cancer progression and metastasis is essential for selecting effective treatment. Using the new gene signature, survival analysis was conducted and a metastasis risk score was developed that provides a practical tool for assessing the risks of metastasis. In the second part, structure-based virtual screening was adopted to investigate which of the already FDA approved drugs can be potentially repositioned to be used against tuberculosis. Because of their known profiles of ADMET, repositioning known drugs for novel indications can shorten the length of time of drug discovery and increase the rate of success. Using virtual screening with molecular docking, a short list of compounds targeting essential TB proteins was identified. More investigations would be needed to further study the potential of the docking hits as repositioning candidates. In the third part, the relationships between moonlighting proteins and diseases were reviewed, and characteristics that correlate with proteins performing moonlighting functions were illustrated. Moonlighting proteins are proteins that have more than one biochemical or biophysical function performed by the same peptide chain. The switching of functions can be activated by a variety of elements such as expression in different cellular localizations. By having moonlighting functions, proteins can coordinate multiple cellular processes in cellular metabolism, which is essential for health. In conclusion, my analysis of gene expression and investigations of protein structure and function explored in three specific areas, which contributes to a better comprehension of the molecular mechanisms of health and disease.

description: This work, interested in handbooks for education and artistic production, proposes to review a selection of three texts, Arte de proyectar en arquitectura (Neufert, 2013 Spanish edition); The fluxus performance workbook (Friedman, 2002 edition); and Hacia una educación sonora (Murray, 2006 Spanish edition), with the objective of identifying in each one the presence of multi, inter and/or transmedia features, to later compare them with each other. These handbooks were selected for having been created as pedagogies, be it architectural ergonomics, actions, or sound, during the last century. Although all of them were originated in different fields, this essay seeks to recognize the mediums used and promoted, as well as to analyze the relationship between them. Our intention is to point out similarities and differences that allow us to better understand them from the perspective that was set.
Switching Sequence-and Switching Transition Control of Power Electronic Systems

Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: In this dissertation, first, an approach for switching sequence (SS)-based control (SBC) for a high frequency higher-order power electronic system (PES) is delineated. This type of control contrasts with a conventional linear-control design of a power-electronic system (PES) where the gains of the control laws are typically determined by small-signal analysis of the averaged model of the PES. The closed-loop control of such a PES using its small-signal model is often found to be unsatisfactory regarding the overall stability and performance, particularly when catering to non-linear time-varying and reduced damped loads. By employing some novel modeling and online optimization techniques, SBC, hence, attempts to control such challenging loads using industrial-scale DSPs and wide bandgap (WBG) GaN-FET and SiC based hardware set-ups. Then this dissertation investigates whether SBC can autonomously shape the conducted EMI spectra of a PES. It is shown by experimental results how SBC does complete differential-mode and reduced-scale common mode EMI mitigation for the PES while maintaining perfect state regulation for the higher-order non-minimum phase PES. This active EMI mitigation by SBC helps in operating the ultra-fast-transition recent wide-bandgap semiconductor devices at higher power with increasing switching frequencies, which is usually desirable for increased power density and reduced switching losses. Finally, the dissertation goes beyond switching sequence synthesis to performing switching transition control (STC) for shaping the rise-and fall times of the switching sequences of the WBG devices. This is done to investigate whether optimality can be created between higher transition speeds of WBG devices and EMI/device stress, to positively impact PES efficiency.
Fabrication and mechanical properties of graphite fiber reinforced aluminum alloys
Creators: name: Esashi, Kiyoyuki
Publisher: name: University of British Columbia
Year: 2010

description: A new method to fabricate continuous graphite fiber reinforced aluminum alloy composites has been developed and the tensile properties of the composites have been investigated. Composites with 601, 201 and 7178 alloy matrix containing up to 19 volume per cent of Thornel 50 graphite fiber were studied. These composites showed lower tensile strength values than the expected values from the "rule of mixture". A theoretical model is discussed in order to understand the tensile properties of these composites. In this mechanism, graphite fibers are thought to be broken continuously one after another at maximum loading point of ultimate tensile strength during the tensile test. A further attempt has been made to improve the tensile strength of these composites, based on the above theoretical work.

description: Different mechanisms for quenching star formation in galaxies are commonly invoked in the literature, but the relative impact of each one at different cosmic epochs is still unknown. In particular, the relation between these processes and morphological transformation remains poorly understood. In this work, we measure the effectiveness of changes in star formation rates by analysing a new parameter, the Star Formation Acceleration (SFA), as a function of galaxy morphology. This methodology is capable of identifying both bursting and quenching episodes that occurred in the preceding 300 Myrs. We use morphological classification catalogs based on Deep learning techniques. Our final sample has $\sim$14,200 spirals and $\sim$2,500 ellipticals. We find that elliptical galaxies in the transition region have median shorter quenching timescales ( $τ$ < 1 Gyr) than spirals ($τ\geq 1$ Gyr). This result conforms to the scenario in which major mergers and other violent processes play a fundamental role in galaxy evolution for most ellipticals, not only quenching star formation more rapidly but also playing a role in morphological transformation. We also find that $\sim$two thirds of galaxies bursting in the green valley in our sample are massive spirals ($M_\star \geq 10^{11.0}M_\odot$) with signs of disturbance. This is in accordance with the scenario where low mass galaxies are losing their gas in a interaction with a massive galaxy: while the former is quenching, the last is being refueled and going through a burst, showing signs of recent interaction.

description: Einstein's General Relativity (GR) is the basis of modern astronomy and astrophysics. Testing the validity of basic assumptions of GR is important. In this work, we test a possible violation of the Weak Equivalence Principle (WEP), i.e., there might be a time-lag between photons of different frequencies caused by the effect of gravitational fields if the speeds of photons are slightly different at different frequencies. We use Fast Radio Bursts (FRBs) , which are astronomical transients with millisecond timescales detected in the radio frequency range. Being at cosmological distances, accumulated time delay of FRBs can be caused by the plasma in between an FRB source and an observer, and by gravitational fields in the path of the signal. We segregate the delay due to dispersion and gravitational field using the post-Newtonian formalism (PPN) parameter $Δγ$, which defines the space-curvature due to gravity by a unit test mass. We did not detect any time-delay from FRBs but obtained tight constraints on the upper limit of $Δγ$. For FRB20181117C with $z = 1.83 \pm 0.28$ and $ν_{obs}$ = $676.5\,{\rm MHz}$, the best possible constraint is obtained at log($Δγ$) = $-21.58 ^{+0.10}_{-0.12}$ and log($Δγ$/$r_{\rm E}$) = $-21.75 ^{+0.10}_{-0.14}$, respectively, where $r_{\rm E}$ is the energy ratio of two photons of the same FRB signal. This constraint is about one order of magnitude better than the previous constraint obtained with FRBs, and five orders tighter than any constraint obtained using other cosmological sources.

description: Mid- and far-infrared (IR) photometric and spectroscopic observations are fundamental to a full understanding of the dust-obscured Universe and the evolution of both star formation and black hole accretion in galaxies. In this work, using the specifications of the SPace Infrared telescope for Cosmology and Astrophysics (SPICA) as a baseline, we investigate the capability to study the dust-obscured Universe of mid- and far-IR photometry at 34 and 70 $μ$m and low-resolution spectroscopy at 17-36 $μ$m using the state-of-the-art Spectro-Photometric Realisations of Infrared-selected Targets at all-z (SPRITZ) simulation. This investigation is also compared to the expected performance of the Origins Space Telescope and the Galaxy Evolution Probe. The photometric view of the Universe of a SPICA-like mission could cover not only bright objects (e.g. L$_{IR}$>10$^{12}$L$_\odot$) up to z=10, but also normal galaxies(L$_{IR}$<10$^{11}$L$_\odot$) up to z$\sim$4. At the same time, the spectroscopic observations of such mission could also allow us to estimate the redshifts and study the physical properties for thousands of star-forming galaxies and active galactic nuclei by observing the polycyclic aromatic hydrocarbons and a large set of IR nebular emission lines. In this way, a cold, 2.5-m size space telescope with spectro-photometric capability analogous to SPICA, could provide us with a complete three-dimensional (i.e. images and integrated spectra) view of the dust-obscured Universe and the physics governing galaxy evolution up to z$\sim$4.

description: Micelle stability in complex biologic fluids is relatively uncharacterized. Much of the work in the field has focused on the influence of proteins, however the influence of complex lipid particles such as lipoproteins is relatively unexplored. The influence of complex biologic fluids and individual human lipoprotein classes on micelle stability was explored utilizing Forster resonance energy transfer and density ultracentrifugation. Cerebrospinal, ascites, and pleural fluid were identified as relatively stable fluids for micelles and appeared to correlate with lipoprotein content. The influence of individual lipoproteins revealed high density lipoprotein as a significant destabilizer of two copolymer micelles. The influence of lipid transfer and potential mixed micelle formation was also explored by MS-ESI/LC-MS/MS as well as SANS, which revealed selective enrichment of several lipid classes and general depletion among others. The potential for lysolipid mixed micelle formation influence on human monocyte derived macrophages was also explored utilizing a known pro-resolving lipid mediator.

description: This study examined the Saudi Twitter responses and shared narratives towards the 2017 women driving decree, a major social reform introduced by the government reform plan, Vision 2030. The study used the theoretical frameworks of Networked Framing theory (Meraz & Papacharissi, 2013), connective action (Bennett & Segerberg, 2012; 2013) to explore the nature of interaction among the Saudis networked publics. Furthermore, Intersectionality (Davis, 2008; McCall, 2005) was used to tease out the intersection of different social structures, cultural, religious, and economic factors that influenced the discourse of women driving. The study employed a mixed-method approach that combined quantitative semantic and social network analyses (SNA) with qualitative discourse analysis. Twitter was an effective tool for mediating Saudi public opinion. The Saudi population seemed to be actively and acutely engaging in using hashtags to preserve their traditions, social values and support their positions. The active use of Twitter led to the emergence of several publics across the network. The Saudi public sphere proved to be a product of political, social, cultural, and religious factors. Saudi society disclosed its vulnerability and willingness to change in response to the new socio-cultural reforms in the country.
Assessing Mastery of Laparoscopic Skills for a Junior Resident Prior to Entering the Operating Room

Publisher: name: University of Illinois at Chicago

description: Background: Simulation has become a standard for developing laparoscopic skills. Common training programs base their passing scores on comparing noncompetent to competent surgeons (Fraser et al., 2003; Thinggaard et al., 2015). With the era of competency-based medical education (CBME), passing scores should be based on the expected skills from the resident for the next stage of training. Purpose: The purpose of this study was to develop a passing score for the CanTAB test which is reflective of the skill expected of a “well-prepared” obs/gyn resident about to start assisting in the OR. The CanTAB test is a modified version of the Training and Assessment of Basic Laparoscopic Techniques (TABLT) test using supplies available in Canada (Thinggaard et al., 2014/2018, 2015). The “well-prepared” resident was operationalized as a resident who could follow explicit instructions, a 2.0 on the Ottawa Surgical Competency Operating Room Evaluation (OSCORE) (Gofton et al., 2012). Methods: Residents and faculty at the University of Manitoba (UofM) obs/gyn department were recruited. Participants could complete any or all of the following: an OR assessment based on the OSCORE and Global Objective Assessment of Laparoscopic Skills (GOALS) tools, the CanTAB test, and/or the mastery Angoff standard-setting exercises informed by a participant’s individual results or the cumulative study results. CanTAB passing scores were calculated using two standard-setting methods: The mastery Angoff and “well-prepared” borderline regression. Results: Eleven participants completed the study: 6 residents and 5 fellows/attendings. The CanTAB scores ranged from 723(123.5) to 1625(503.4), with senior residents scoring the highest. The CanTAB passing scores were 602 for mastery Angoff-1, 862 for mastery Angoff-2, 993 (p=0.005) for the “well-prepared” regression line between the OSCORE and CanTAB scores, and 1270 (p=0.469) for the “well-prepared” regression line between the GOALS and CanTAB scores. The passing rates ranged from 25 to 100%, with the OSCORE-based regression line having the second-lowest passing rate with 25% of junior residents and 100% of senior residents and attendings passing. Conclusion: A CanTAB passing score of 993, based on the OSCORE level of 2.0 well-prepared borderline regression method, can best identify resident well-prepared to assist laparoscopic surgery with explicit instructions in the OR.
Modeling Health Coaching Dialogues for Behavioral Goal Extraction

description: Health coaching has been identified as a successful method for motivating and maintaining health behavior changes. Unfortunately, personal health coaching is time- and resource-intensive, and cannot scale up. Previous research focuses on developing conversational systems that can provide automated coaching to patients. But most of these systems rely on a predefined set of input/output mappings, focus more on general goal setting, and do not provide follow-up during goal implementation. Therefore, my research contributes to building a virtual assistant health coach to help patients set and achieve a Specific, Measurable, Attainable, Realistic, and Time-bound (SMART) goal. The first step towards building a successful domain-specific dialogue system is to understand the users' needs and the environment in which it will be used. Since no other public health coaching dialogue data exists, we collected data that I annotated for a variety of features of interest. These annotations include domain-specific slots called SMART attributes at the word level, the intent behind a participant's text message called dialogue acts, and higher-level portions of the dialogue performing a specific function called stages and phases. I then used these annotations to build the language understanding component of the dialogue system and design the goal extraction pipeline, which extracts the physical activity goal the user and coach negotiate via text messages. I proposed a two-step goal extraction process that uses phases and dialogue acts to identify the correct SMART goal attributes and show that dialogue acts help more than the higher-level conversation flow captured by phases. These goal summaries will help the health coaches to easily recall patients' past goals and use them to suggest a realistic future goal. Finally, I assessed the usability of the generated goal summaries with the help of three health coaches in an offline setting.

description: We develop a high-performance analytical model of Galactic Chemical Evolution, which accounts for delay time distributions and lock-up of stellar yields in a thermal-phased ISM. The model is capable of searching, for the first time, through the high-dimensional parameter space associated with the r-process enrichment of the Milky Way by its possible sources: Neutron Star Mergers and Collapsar events. Their differing formation mechanisms give these two processes different time dependencies, a property which has frequently been used to argue in favour of collapsars as the dominant r-process source. However, we show that even with large degrees of freedom in the allowed thermal, structural, and chemical properties of the galaxy, large regions of parameter space are in strong tension with the data. In particular, whilst we are able to find models in which neutron star mergers produce the majority of r-process material, the data rule out all models with dominant collapsar yields. With no other identified source, we conclude that Neutron Star Mergers must be the dominant contributors to the modern Milky Way r-process budget.

Clarifying Forecasts of Dark Energy Constraints from Baryon Acoustic Oscillations

description: The measurement of baryon acoustic oscillations (BAO) from a galaxy redshift survey provides one of the most promising methods for probing dark energy. In this paper, we clarify the assumptions that go into the forecasts of dark energy constraints from BAO. We show that assuming a constant nP_{0.2}/G^2(z) (where P_{0.2} is the real space galaxy power spectrum at k=0.2h/Mpc and redshift z) gives a good approximation of the observed galaxy number density expected from a realistic flux-limited galaxy redshift survey. We find that assuming nP_{0.2}/G^2(z)=10 gives very similar dark energy constraints to assuming nP_{0.2}=3, but the latter corresponds to a galaxy number density larger by ~70% at z=2. We show how the Figure-of-Merit (FoM) for constraining dark energy depends on the assumed galaxy number density, redshift accuracy, redshift range, survey area, and the systematic errors due to calibration and uncertainties in the theory of nonlinear evolution and galaxy biasing. We find that an additive systematic noise of up to 0.4-0.5% per dz=0.1 redshift slice does not lead to significant decrease in the BAO FoM.

description: We investigate the static and ultrafast magneto-optical response of the hexagonal chiral helimagnet $Cr_{1/3}NbS_{2}$ above and below the helimagnetic ordering temperature. The presence of a magnetic easy plane contained within the crystallographic ab-plane is confirmed, while degenerate optical pump-probe experiments reveal significant differences in the dynamic between the parent, $NbS_{2}$, and Cr-intercalated compounds. Time resolved magneto-optical Kerr effect measurements show a two-step demagnetization process, where an initial, sub-ps relaxation and subsequent buildup ($τ> 50$ ps) in the demagnetization dynamic scale similarly with increasing pump fluence. Despite theoretical evidence for partial gapping of the minority spin channel, suggestive of possible half metallicity in $Cr_{1/3}NbS_{2}$, such a long demagnetization dynamic likely results from spin lattice-relaxation as opposed to minority state blocking. However, comparison of the two-step demagnetization process in $Cr_{1/3}NbS_{2}$ with other 3d intercalated transition metal dichalcogenides reveals a behavior that is unexpected from conventional spin-lattice relaxation, and may be attributed to the complicated interaction of local moments with itinerant electrons in this material system.

description: Formation and evolution of the elliptic flow pattern in Pb+Pb collisions at sqrt{s}=5.5 ATeV and in Au+Au collisions at sqrt{s}=200 AGeV are analyzed for different hadron species within the framework of HYDJET++ Monte-Carlo model. The model contains both hydrodynamic state and jets, thus allowing for a study of the interplay between the soft and hard processes. It is found that jets are terminating the rise of the elliptic flow with increasing transverse momentum. Since jets are more influential at LHC compared to RHIC, the elliptic flow at LHC should be weaker than that at RHIC. The influence of resonance decays on particle elliptic flow is investigated also. These final state interactions enhance the low-p_T part of the v_2 of pions and light baryons, and work towards the fulfilment of idealized constituent quark scaling.

description: Galaxy clusters grow by accreting galaxies from the field and along filaments of the cosmic web. As galaxies are accreted they are affected by their local environment before they enter (pre-processing), and traverse the cluster potential. Observations that aim to constrain pre-processing are challenging to interpret because filaments comprise a heterogeneous range of environments including groups of galaxies embedded within them and backsplash galaxies that contain a record of their previous passage through the cluster. This motivates using modern cosmological simulations to dissect the population of galaxies found in filaments that are feeding clusters, to better understand their history, and aid the interpretation of observations. We use zoom-in simulations from The ThreeHundred project to track halos through time and identify their environment. We establish a benchmark for galaxies in cluster infall regions that supports the reconstruction of the different modes of pre-processing. We find that up to 45% of all galaxies fall into clusters via filaments (closer than 1Mpc/h from the filament spine). 12% of these filament galaxies are long-established members of groups and between 30 and 60% of filament galaxies at R200 are backsplash galaxies. This number depends on the cluster's dynamical state and sharply drops with distance. Backsplash galaxies return to clusters after deflecting widely from their entry trajectory, especially in relaxed clusters. They do not have a preferential location with respect to filaments and cannot collapse to form filaments. The remaining pristine galaxies (30 - 60%) are environmentally effected by cosmic filaments alone.

description: We present a comprehensive theory of spin transport in a non-degenerate semiconductor that is in contact with multiple ferromagnetic terminals. The spin dynamics in the semiconductor is studied during a perturbation of a general, non-collinear magnetization configuration and a method is shown to identify the various configurations from current signals. The conventional Landauer-Büttiker description for spin transport across Schottky contacts is generalized by the use of a non-linearized I-V relation, and it is extended by taking into account non-coherent transport mechanisms. The theory is used to analyze a three terminal lateral structure where a significant difference in the spin accumulation profile is found when comparing the results of this model with the conventional model.

description: The differences between groups working in the German psychotherapeutic care system are incomprehensible to laypeople, as the job titles are very similar despite the protection of titles. However, the differences in access requirements, training, examinations and liability between groups are significant (Hollunder, 2017). The main aim of the project is to compare different groups working in the German psychotherapeutic care system as well as laypersons regarding their abilities in clinical psychology and psychotherapy. We aim to compare four groups: 1) psychologists (postgraduate psychotherapy trainees), 2) psychology students, 3) non-academically trained providers of complementary and alternative medicine (CAM, e.g., so called “Heilpraktiker”, psychological counsellors, coaches or similar professions), and 4) laypersons. An online study will be conducted using video case vignettes (the Pro CliPs Task) to assess procedural clinical knowledge. We will further assess participants’ declarative clinical knowledge and their psychotherapeutic self-efficacy (except for laypersons).

description: During the last few decades, great effort has been made towards understanding hydrodynamical processes which determine the structure and evolution of stars. Up to now, the most stringent constraints have been provided by helioseismology and stellar cluster studies. However, the contribution of asteroseismology becomes more and more important, giving us an opportunity to probe the interiors and atmospheres of very different stellar objects. A variety of pulsating variables allows us to test various parameters of micro- and macrophysics by means of oscillation data. I will review the most outstanding key problems, both observational and theoretical, of which our knowledge can be improved by means of asteroseismology.

description: The PANOSETI experiment is an all-sky, all-the-time visible search for nanosecond to millisecond time-scale transients. The experiment will deploy observatory domes at several sites, each dome containing ~45 telescopes and covering ~4,440 square degrees. Here we describe the focal-plane electronics for the visible wavelength telescopes, each of which contains a Mother Board and four Quadrant Boards. On each quadrant board, 256 silicon photomultiplier (SiPM) photon detectors are arranged to measure pulse heights to search for nanosecond time-scale pulses. To simultaneously examine pulse widths over a large range of time scales (nanoseconds to milliseconds), the instrument implements both a Continuous Imaging Mode (CI-Mode) and a Pulse Height Mode (PH-Mode). Precise timing is implemented in the gateware with the White Rabbit protocol.

description: Socio-psychological factors can influence efforts to conserve biodiversity. Despite numerous studies focused on giant panda (Ailuropoda melanoleuca) conservation, the intentions of farmers with respect to these conservation practices have received little attention. This paper uses an expanded version of the theory of planned behavior (TPB) as a framework to identify the socio-psychological factors that influence farmers’ intentions to adopt conservation practices. The TPB hypothesizes that intention is determined by three psychological constructs: attitude, subjective norms, and perceived behavioral control. Perceived resources and some socioeconomic issues are also considered in the expanded TPB framework. A structured survey of 506 farmers was conducted, with farmers categorized into groups who received and did not receive subsidy payments. A principle components analysis was applied to check the structure of the latent TPB constructs. We used a logistic model to identify the impact of perceived resources, attitude, subjective norms, perceived behavioral control, and other socioeconomic characteristics on farmers’ intentions to adopt conservation practices. Results show that the intentions of subsidized conservation participants were significantly influenced by perceived resources, behavioral control, attitude, and subjective norms. Non-subsidized conservation participants were significantly influenced by perceived resources, behavioral control, and subjective norms. Numerous socioeconomic factors were also significantly associated with intentions. To improve the adoption of sustainable conservation practices by farmers, attention should be paid to both psychological and socioeconomic issues that could improve the sustainability of A. melanoleuca conservation and the livelihoods of farmers in southwest China.

description: COVID-19 pandemic is an ongoing global pandemic which has caused unprecedented disruptions in the public health sector and global economy. The virus, SARS-CoV-2 is responsible for the rapid transmission of coronavirus disease. Due to its contagious nature, the virus can easily infect an unprotected and exposed individual from mild to severe symptoms. The study of the virus effects on pregnant mothers and neonatal is now a concerning issue globally among civilians and public health workers considering how the virus will affect the mother and the neonates health. This paper aims to develop a predictive model to estimate the possibility of death for a COVID-diagnosed mother based on documented symptoms: dyspnea, cough, rhinorrhea, arthralgia, and the diagnosis of pneumonia. The machine learning models that have been used in our study are support vector machine, decision tree, random forest, gradient boosting, and artificial neural network. The models have provided impressive results and can accurately predict the mortality of pregnant mothers with a given input.The precision rate for 3 models(ANN, Gradient Boost, Random Forest) is 100% The highest accuracy score(Gradient Boosting,ANN) is 95%,highest recall(Support Vector Machine) is 92.75% and highest f1 score(Gradient Boosting,ANN) is 94.66%. Due to the accuracy of the model, pregnant mother can expect immediate medical treatment based on their possibility of death due to the virus. The model can be utilized by health workers globally to list down emergency patients, which can ultimately reduce the death rate of COVID-19 diagnosed pregnant mothers.

description: 3D modeling based on point clouds requires ground-filtering algorithms that separate ground from non-ground objects. This study presents two ground filtering algorithms. The first one is based on normal vectors. It has two variants depending on the procedure to compute the k-nearest neighbors. The second algorithm is based on transforming the cloud points into a voxel structure. To evaluate them, the two algorithms are compared according to their execution time, effectiveness and efficiency. Results show that the ground filtering algorithm based on the voxel structure is faster in terms of execution time, effectiveness, and efficiency than the normal vector ground filtering.
