description: Models of a playground swing have been studied since the 1960s. However, in most of them, the position of the swinger is controlled directly. This simplifies the problem but hides the mechanics of torques applied to keep the swing moving in a regular pattern. This article studies these mechanics. Two models of a swing with torques as controls that we consider are identical to popular models of modern robotics: the Acrobot and reaction wheel pendulum. However, the control task of sustaining the swing's regular oscillations by a static feedback control is new and challenging, especially when damping in the joint connecting the swing to the frame is considered. We develop two types of controls to accomplish this task. One works for small damping and is based on linearizing the undamped system by a suitable preliminary feedback control. The other works for large damping. In the steady state, the resulting closed-loop system describes a harmonically driven damped pendulum (a simple system known for its complex behavior), including chaotic motion for some parameter values. To address such complexities, we build free parameters into the controls, then adjust them based on simulations to avoid chaos and achieve regular oscillations that are seen on playgrounds.

description: A considerable change is going on in Norwegian building industry. Due to higher ambitions in energy regulations, focus has returned to the importance of improved air tightness. A stronger need to document this property have led to one acknowledgement
of much more frequent measuring of air tightness being needed. There have been different approaches to possible cost reduction for this through a series of different methods being studied. Simple equipment for measuring has been developed, as an initiative from the Norwegian building industry.
Very encouraging results are beginning to manifest itself from the process of measuring, repairing defects and adjusting detailing.
Different approaches to documenting air tightness by measuring are presented together with practical examples from buildings of different types.

Migratory and Differentiation Mechanisms Coordinate Olfactory Neurogenesis

description: Neurogenesis requires the coordination of many processes including cell spatial patterning and differentiation. How these parts integrate to ensure proper organ assembly and function is challenging to understand in vivo, especially given the stochastic nature of vertebrate development. Here, I leverage imaging of the developing zebrafish olfactory epithelium to quantitatively investigate mechanisms of cellular spatial patterning and differentiation. I found that precursors thought to be derived from migratory neural crest cells exhibited different movement characteristics as compared to local, placode-derived precursors. Despite this, both neuronal precursor types displaced such that the cells tended to condense toward an apical-basal midline within the tissue, pointing to a radial, convergence-like coordination. Next, I investigated how Notch signaling and the transcription factor insm1a manifest their mutual antagonism and control of olfactory neurogenesis. Groups of contacting cells with reciprocal expression assemble in a lateral inhibition-like pattern in the basal olfactory epithelium. These ‘Neighborhoods’ express higher levels of the proneural gene neurod4 than other basal cells and are preferentially regulated by the morphogen retinoic acid, which has a pro-neurogenic effect and likely diffuses from the adjacent developing eye. Together, these data indicate an interorgan signaling axis that regulates neurodevelopment in vivo.

description: In Flanders the practical implementation of investments in main sewers and treatment plants and the exploitation of it, is carried out by Aquafin. The investments are commissioned by the Flemish government, who wants to introduce a result commitment that is function of the performance of the management of the waste water transport and treatment system. To realise this, a framework of performance indicators was worked out and tested. For the typical Flemish waste water system this framework of performance indicators was set up with respect to the optimal management of the system (treatment plant + urban drainage system). First, a literature study was carried out in order to find similar examples in other countries. In the second phase a basic framework of performance indicators was set up based on the knowledge of the waste water system, the literature and the available measurements. The focus was to use as much as possible (easily and objectively) measurable parameters for the calculation of the performances. In a third phase this framework was tested on three pilot cases, i.e. the total drainage system to three different treatment plants. In the final phase the methodology was further refined and finalised.

description: In this paper we applied the psychometric paradigm to validate a questionnaire that assesses the risk perception characteristics of flooding and water nuisance. The state-trait anxiety inventory was used as a bench mark to determine whether perceptions are related to anxiety characteristics. A focus group was used to further validate the questionnaire. Factor analyses of 49 questionnaires identified eight flooding factors (explained variance: 74%) and three water nuisance factors (explained variance: 62%). Internal consistencies of the obtained scales were moderate to high. Like in the perception of external safety risks, \342\200\230dread\342\200\231 seems to be the most important concept binding different characteristics. Although dread towards both flooding and water nuisance is rather low, it seems more present in the latter case. Furthermore, the extent of dread for water nuisance seems related to someone\342\200\231s state anxiety. In both cases awareness of \342\200\230increasing risks\342\200\231 is clearly present, and we find the characteristics \342\200\230(no) dread\342\200\231, \342\200\230(un)controllable situation\342\200\231 and \342\200\230does not affect me\342\200\231 to be related.
Positioning of African Art in the Global Art Market: A Look at Western Attitudes and Influences in the Lives of Contemporary African Artists in the United States

global art market

description: The success of a contemporary African artist depends on how well the artist does
in the global art market. The purpose of a global art market is to respectfully promote
and equally recognize cultural others. However, the global art market has consistently
been regulated under Western cultural, political, and economic systems. Western values
dominate and marginalize other cultures such as contemporary African artists living in
the United States. As a result, contemporary African artists are positioned on the
periphery of the global art market.  It is white male artists in the working and upper
classes who gain the most social and economic privileges. Certain Western societies
have not been as open and receptive to contemporary African artists as they have been to
white male artists. The purpose of the study is to recognize behaviors that marginalize
African artists in the art market, learn of contemporary African art, and create a dialogue
that could change the positioning of contemporary African art in the global market. I
identify Western behaviors that are particularly modeled after, but not limited to, the
attitudes and influences related to the colonization (16*'’- 20*'’ century) and postcolonization
(20*'’ -21®* century) of Africa by Europe and the United States of America. Even though some ethnographic museums and fine art galleries in the United States have
made a place for traditional Afiican art, the on-going absence of contemporary Afncan
artists reinforces colonial attitudes in today’s global art market. Such attitudes regard the
paradigm of Afncan art as primitive, exotic, and inferior to Western art. Those in the art
market who possess these attitudes refuse to view and, thus, accept modem concepts
from contemporary African artists. In order to change prejudicial attitudes in the global
art market, they must be recognized. Then, it is up to the individual to widen his
perspectives. Studying contemporary Afncan artists living in the United States may
encourage some Western societies to alter certain behaviors when regarding other
cultural art. This research discusses Western attitudes that influence the global art market. In
addition, it examines arguments against categorizing Western art as central and Afncan
art as peripheral in post-modem and pluralistic societies. It also analyzes how
contemporary Afncan artists and Westerners view traditional Afncan art and the legacy
of traditional Afncan art in Afiican and Western contemporary art. Finally, this analysis
examines the unfair presentation of contemporary Afncan art in Western museums and
galleries.
Psychometric Evaluation of a Kinyarwanda Intimate Partner Violence Instrument among Rwandan Women

description: In the East African country of Rwanda, 1 in 3 women experience a form of gender-based violence throughout their life span. Currently, there is no established clinical screening tool, nor standardized screening process in place within the healthcare system. Although many valid clinical GBV screening tools exist for use within different settings, the Assessment Screen to Identify Survivors Toolkit for Gender Based Violence (ASIST-GBV) was recently created for use in low resource and humanitarian areas, including post-conflict areas associated with refugee and internally displaced peoples. The ASIST-GBV has been previously tested and reported as a valid tool in similar contexts to Rwanda but had not been translated to Kinyarwanda (the indigenous language) or tested there. Thus, the objectives of this doctoral dissertation were to translate and adapt the ASIST-GBV to the Rwandan context, establish the psychometric properties of the new Kinyarwanda ASIST-GBV, and to identify factors associated with GBV from among women screened using the Kinyarwanda ASIST-GBV. Cognitive interviewing of 20 Kinyarwanda speaking Rwandan women was conducted to establish contextual validation of the translated version. This modified Kinyarwanda version of the ASIST-GBV was administered to a sample of two hundred women at a large public hospital in central Rwanda. Item response theory (IRT) testing provided evidence of the tool’s reliability and validity. Multivariate logistic regression modeling was fit to the data and five risk factors associated with GBV in the best fit model are reported, along with the probabilities of experiencing GBV for each factor among these women. These findings reveal that the Kinyarwanda ASIST-GBV is both valid and functional in screening women in a healthcare setting, while also confirming a high rate of GBV occurring within the sample. The risk factors are useful in informing collaboration with the Ministry of Health to create policies for using the screening tool appropriately to fill the existing gap between GBV survivors and available resources. Further modifications towards a shortened version of the Kinyarwanda ASIST-GBV should be tested for efficient use in the clinical setting

description: Domain adaptive text classification is a challenging problem for the large-scale pretrained language models because they often require expensive additional labeled data to adapt to new domains. Existing works usually fails to leverage the implicit relationships among words across domains. In this paper, we propose a novel method, called Domain Adaptation with Structured Knowledge (DASK), to enhance domain adaptation by exploiting word-level semantic relationships. DASK first builds a knowledge graph to capture the relationship between pivot terms (domain-independent words) and non-pivot terms in the target domain. Then during training, DASK injects pivot-related knowledge graph information into source domain texts. For the downstream task, these knowledge-injected texts are fed into a BERT variant capable of processing knowledge-injected textual data. Thanks to the knowledge injection, our model learns domain-invariant features for non-pivots according to their relationships with pivots. DASK ensures the pivots to have domain-invariant behaviors by dynamically inferring via the polarity scores of candidate pivots during training with pseudo-labels. We validate DASK on a wide range of cross-domain sentiment classification tasks and observe up to 2.9% absolute performance improvement over baselines for 20 different domain pairs. Code will be made available at https://github.com/hikaru-nara/DASK.

description: In this paper, a simple model concept is presented to describe the dynamics of road runoff and suspended-solid transport from a small urban catchment in northern Sweden. The study period stretches from March 28 to May 28, 2000, including both snowmelt and rainfall. A modified degree-day method is used to describe the snowmelt and the transport of suspended solids is described by a linear build-up function and a wash-off model. The model was verified through measurements taken from March 22 to May 22, 2001. The results from the simulations showed that the simple model concept was capable of describing the dynamics of road runoff and suspended solids rather well, based on the continuous course of events for the whole modelling period. However, if the model was used for simulating a snowmelt period, or single events during snowmelt, the model approach would be too simple.

description: Spiking Neural Networks (SNNs) have recently emerged as the low-power alternative to Artificial Neural Networks (ANNs) owing to their asynchronous, sparse, and binary information processing. To improve the energy-efficiency and throughput, SNNs can be implemented on memristive crossbars where Multiply-and-Accumulate (MAC) operations are realized in the analog domain using emerging Non-Volatile-Memory (NVM) devices. Despite the compatibility of SNNs with memristive crossbars, there is little attention to study on the effect of intrinsic crossbar non-idealities and stochasticity on the performance of SNNs. In this paper, we conduct a comprehensive analysis of the robustness of SNNs on non-ideal crossbars. We examine SNNs trained via learning algorithms such as, surrogate gradient and ANN-SNN conversion. Our results show that repetitive crossbar computations across multiple time-steps induce error accumulation, resulting in a huge performance drop during SNN inference. We further show that SNNs trained with a smaller number of time-steps achieve better accuracy when deployed on memristive crossbars.

A Critical Analysis of the Perceptions and Experiences of Teachers about Diversity and Equity

description: Schools are not designed to accommodate or attend to the cultures and identities of all students. Despite eighty years of educational justice research focused on understanding and dismantling assimilationist models of education, our educational system continues to fail youth who identify as BIPOC and/or ethnically marginalized. In many schools, including the focal school in this case study, diversity and equity initiatives are implemented by administrators in order to move schools towards equitable education practices. Recognizing that teachers’ perceptions and experiences of diversity and equity are integral to the implementation of any diversity and equity initiative, this study analyzed five focus groups (n=31) and five one-on-one interviews (n=5) with teachers at one school. Findings reveal the importance of teacher responsibility for enacting and engaging in diversity and equity initiatives and the manner in which teachers’ fears and anxieties can hinder fostering positive teacher-student relationships with students who identify as BIPOC and/or ethnically marginalized. This case study highlights the importance of considering teacher responsibility and teacher emotions in the creation of diversity and equity initiatives. It also has implications for the design of effective professional development and the need for culturally sustaining relationships as a pedagogical practice to move schools towards educational equity.
Crucial role of vibrational entropy in the Si(111)-7$\times$7 surface structure stability

description: We investigate the relative thermodynamic stability of the $3\times3$, $5\times5$, $7\times7$, $9\times9$ and infinitely large structures related to the dimers-adatoms-stacking faults family of Si$(111)$ surface reconstructions by means of first-principles calculations. Upon accounting for the vibrational contribution to the surface free energy, we find that the $5\times5$ structure is more stable than the $7\times7$ at low temperatures. While a phase transition is anticipated to occur at around room temperature, the $7\times7\rightarrow5\times5$ transformation upon cooling is hindered by the limited mobility of Si atoms. The results not only flag a crucial role of vibrational entropy in the formation of the $7\times7$ structure at elevated temperatures, but also point for its metastable nature below room temperature.
Racial Socialization in Black-White Interracial Families

description: Today, we know that black-white interracial couples and their progeny are a continuously increasing segment of the U.S. population. There is a dearth of research, however, that examines the ways in which these parents provide racial socialization to their children. The scholarship that does exist on interracial families suggests that racial socialization may be more complicated within interracial families where family members do not necessarily share similar racial identities. Whereas the existing research on black-white racial socialization has been largely focused on identity, this research explores racial identity as just one avenue of a broader racial socialization process. Utilizing a qualitative approach, in-depth interviews were conducted with 31 parents with children from black-white interracial families. This research contributes to our understanding of both racial socialization in interracial families and intersectionality as it informs parenting practices. More specifically, this research offers insight on the following two questions: 1) How do black-white interracial couples understand race? 2) And, how do black-white interracial couples help their children to understand and navigate race, racial identity, and racism. Findings from this research suggest that parents’ understandings of race are not contingent upon a parent’s race nor intersection of race and gender. The research offers evidence to support that parents provide racial socialization with different levels of intentionality. Additionally, this research suggests that intersections of children’s race and gender inform how parents talk with their children about race and racism.

description: Physical activity is known to help improve and maintain one's health. In particular, recreational running has become increasingly popular in recent years. Yet, lack of motivation often interferes with people's routines and thus may prohibit regular uptake. This is where running tracking applications are frequently used to overcome one's weaker self and offer support. While technology artifacts, such as sport watches or running applications, usually count as extrinsic drivers, they can also impact one's intrinsic motivation levels. The aim of this study was thus to investigate upon the motivational impact of distinct features found within applications specifically used for running. Focusing on the 22 most famous running applications, a semi-structured, problem-centered interview study with $n=15$ recreational runners showed that intrinsic motivation is stimulated from diverting runners, aiding them in their goal setting, decreasing their efforts, improving and sharing their run performance, allowing them to receive acknowledgements, as well as providing them with guidance, information, and an overall variety in their training routines.

Senescent Cells Promote Liver Regeneration Through IL-6 and Ligands of CXCR2
Creators: name: Cheng, Naiyuan
Publisher: name: University of Illinois at Chicago
Year: 2022
Subjects: Uncategorized

description: Senescent cells have long been associated with deleterious effects in aging-related pathologies, although more recent studies have uncovered their beneficial roles in certain contexts such as wound healing. We have found that hepatic stellate cells (HSCs) undergo senescence within two days after 2/3 partial hepatectomy (PHx) in young (2-3 month-old) mice, and elimination of these senescent cells by the senolytic drug ABT263 or using a genetic mouse model impairs liver regeneration. Senescent HSCs secrete IL-6 and CXCR2 ligands as part of the senescence-associated secretory phenotype (SASP), which induces multiple signaling pathways to stimulate liver regeneration. IL-6 activates STAT3, induces YAP activation through SRC family kinases, and synergizes with CXCL2 to activate ERK1/2 to stimulate hepatocyte proliferation. The administration of either IL-6 or CXCL2 partially restores liver regeneration in mice with senescent cell elimination, and the combination of both fully restores liver weight recovery. Furthermore, the matricellular protein CCN1/CYR61 is rapidly elevated in response to PHx and induces HSC senescence. Knock-in mice expressing a mutant CCN1 unable to bind integrin α6β1 are deficient in senescent cells and regenerative responses after PHx. Thus, HSC senescence, in part induced by CCN1, is a programmed response to PHx and plays a critical role in liver regeneration through signaling pathways activated by IL-6 and ligands of CXCR2.

description: Recording a stellar occultation is one powerful method that gives direct information about the physical properties of the occulting solar system object. In order to obtain reliable and accurate results, simultaneous observations from different locations across-track of the projected path are of great importance. However, organising all the observing stations, aggregating, and analysing the data is time-consuming and not that easy. We have developed a web portal named Occultation Portal (OP) to manage all those occultation observation campaigns from a central server. With this portal, the instrumental and observational information of all observers participating in a stellar occultation campaign and the concerned data are archived systematically in a standard format. The researchers can then visualise the archived data on an event basis. The investigators can also extract the light curve for each data-set with the added reduction pipeline to the portal base. This paper describes in detail the portal structure and the developed features.

description: Recent tragedies of flooding in urban areas like Bordeaux (1982), N\303\256mes (1988) or Marseille (2000) have led stakeholders and technicians to lean on this issue. Sewage systems for rainfalls are generally designed for events with a return period of ten years whereas more severe events lead to runoff on the streets and unfortunately to damages of goods and sometimes human casualties. This work aims at improving surface flow models in urban area through a project gathering several organizations from the French Ministry of Public Works and scientists. Applications are made with this model on the catchment area of an urban district of Marseille named Vieux-Port and on a district area of Bordeaux named La Grenouill\303\250re.

A Method for more specific Simulation of Operative Temperature in Thermal Analysis Programmes

Year: 2008

description: Simulations programs on hourly basis for energy consumption and indoor climate have traditionally been based on a relative simple model for the operative temperature independently of the location of the person in the room. In practice the location of the person has a significant influence in buildings with greater glass surfaces. A person behind a window directly exposed to the direct sun light will have a completely different operative temperature than a person behind in the room in the shadow or in an area with shading devices.

Designing rooms with big glass areas therefore has a great effect of the thermal comfort in the rooms. When calculating the consequences for the thermal indoor climate, the surface temperature is an important factor. To find a simple measure for the heat loss from a person, the operative temperature can be used. The mean radiant temperature plays an important part in calculating the operative temperature and here the angular factor is used.

The air temperature and the temperature on the surfaces can easily be calculated. When one wants to find the angular factor between two surfaces, one can find a specific equation for the angular factor to be used in the calculations. However, the real problem is calculating the mean value of angular factor between a seated/standing person and a vertical/horizontal rectangle since there are no direct formula for calculation of the angular factor between the surface and a person.

This paper deals with a method for solving this problem by going through a complicated iteration process for all cases and setting up a solution matrix to be used in computer analysis programmes.

Elucidating Molecular Mechanisms Involved in Rgg-SHP Transcription Regulation During Streptococcal quoru

description: Rgg proteins are a class of peptide pheromone-binding transcriptional regulators found in the cytoplasm of most genera of the bacterial phylum Firmicutes. In Group A Streptococcus (GAS), Rgg2 and Rgg3 proteins regulate the transcription of genes involved in moderating group behaviors such as biofilm formation, lysozyme resistance, cell aggregation, and immunosuppression1, in a process known as quorum sensing (QS). A short hydrophobic peptide (SHP) induces QS-related genes by altering the function of the individual Rgg transcriptional regulators. Interestingly, Rgg2 and Rgg3, though highly similar proteins, display opposing activities in transcription regulation; Rgg2 is an activator, whereas Rgg3 is a repressor. We are characterizing the properties of these Rgg proteins, including peptide binding, DNA binding, interactions with RNA polymerase, and oligomerization. The goal is to characterize how these SHP-responsive proteins undergo allosteric conformational shifts resulting in positive recruitment and/or interaction with RNA polymerase holoenzyme. Using biochemical and genetic approaches, we found that SHP induces a conformational shift in Rgg proteins resulting in productive interactions with RNA polymerase holoenzyme and initiation of transcription. Understanding how Rgg proteins initiate or block transcription, and how their activity changes when bound to the SHP pheromones, will advance our understanding of QS in GAS and other pathogenic members of the phylum Firmicutes. Characterization of Rgg-SHP systems expands our efforts to interfere with QS and therefore manipulate bacterial behavior for therapeutic purposes.

Regulation of Protein Tyrosine Kinase 6 Stability and Activation

description: Protein Tyrosine Kinase 6 (PTK6) is an intracellular tyrosine kinase whose functions depend on its localization. When localized at the plasma membrane in prostate cancers, PTK6 promotes oncogenic signaling and is associated with worse patient outcomes. PTK6 acts growth inhibitory when it is localized in the nucleus. PTK6 lacks membrane targeting domains and nuclear localization sequences, and mechanisms of regulation of intracellular localization are not well understood. The SH2 domain of PTK6 was identified as crucial for the interaction with plasma membrane lipids which was shown to be mediated by two arginine residues, R131 and R136. Mutation of these residues did not lead to reduction in lipid binding. We show that PTK6 preferentially binds monophosphorylated phosphoinositides. Mutation of R131 and R136 led to increase in PTK6 stability. In contrast, mutation of amino acid residues R85 and H126 which are involved in binding of phosphotyrosines, led to accumulation of PTK6 in cellular granules and reduced stability. We demonstrate that wild type PTK6 and phosphotyrosine binding mutant interact with Cul1 and SKP1, which are components of Cullin Ring Ligase 1 E3 ubiquitin ligase complex. The more stable previously described as lipid binding mutant, does not interact with this complex. Mutation of PTK6 amino residue R131 has been reported in some cancers, which may contribute to increased PTK6 stability, activity, and cancer signaling. We show that activity of PTK6 is inhibited by Vemurafenib, in vitro and in vivo. Vemurafenib reduces proliferation and increases cell death in xenograft tumors, which suggests that PTK6 could be targeted in cancers. I found that calcium-binding protein, calmodulin can bind PTK6 and increase its autophosphorylation, which could be one of the pathways PTK6 is activated in differentiation of keratinocytes upon increase in calcium ion levels.

description: The Turing completeness of continuous chemical reaction networks (CRNs) states that any computable real function can be computed by a continuous CRN on a finite set of molecular species, possibly restricted to elementary reactions, i.e. with at most two reactants and mass action law kinetics. In this paper, we introduce a notion of online analog computation for the CRNs that stabilize the concentration of their output species to the result of some function of the concentration values of their input species, whatever changes are operated on the inputs during the computation. We prove that the set of real functions stabilized by a CRN with mass action law kinetics is precisely the set of real algebraic functions.

description: Full-scale stud cavities were constructed in a climate-controlled chamber to investigate the capacity of wall cavities under experimental conditions to contain mold products, emanating from studs with 10% of their surfaces covered with mold, from penetrating the indoor space. The project investigated the transport of microbical volatile organic compounds (MVOCs), which can be byproducts of mold growth, through the building envelope, and assesses whether the concentration of MVOCs was related to six experimental parameters stated below. The tests were initially designed primarily to study the movement of fungal spores. Later, additional information was collected to investigate the movement of MVOCs. Full size wall assemblies of residential wood frame buildings were constructed, and subjected to air infiltration rates typical of houses in the Quebec region, Canada. A stainless steel sampling chamber, simulating the indoor space, was constructed to encase the inner face of the central stud cavity of the specimens, and to provide controlled depressurization for the air infiltration. The parameters that may influence spores and MVOCs movement selected for the investigation were the air leakage characteristics (air leakage path and rate) and wall configurations (insulation, vapour barrier and sheathing material).  The analysis of VOCs was performed using gas chromatography/ mass spectrometry (GC/MS) to identify the volatile species in the stud space, the interior of the sampling chamber and the ambient laboratory air.  The results were analyzed using multiple regression analysis to determine the transport through the building envelope.

description: The new ventilation regulations in England and Wales (2006) introduced performance criteria for the control of mould. The UK Government's Building Regulations Research Programme funded University College London (UCL) to investigate the extent to which these are the most appropriate criteria for the control of mould in UK dwellings. This paper details work which includes an analysis of data from a national study of England's Home Energy Efficiency scheme (Warm Front). Surveys were undertaken of dwellings and households participating in the scheme in five urban areas. Half-hourly living room and main bedroom temperatures and relative humidity measurements were recorded for two to four weeks (in the heating season) in approximately 1600 dwellings. This data was also analysed to investigate the typical conditions that exist in UK dwellings and also any relationship that exists between these levels and the mould growth that was recorded.  The paper also reports on extensive field work that was undertaken for other sets of dwellings in combination with laboratory and modelling work.  The recommendations for the next revision of the regulations are described.
