LEVAX: An Input-Aware Learning-Based Error Model of Voltage-Scaled Functional Units

As Moore’s Law comes to an end and transistor scaling increasingly falls short in improving energy efficiency, alternative computing paradigms are direly needed. This need is further highlighted by the overwhelming increase in computing demand posed by emerging applications, such as multimedia and data analysis. Fortunately, such driving workloads also present new opportunities since, thanks to their inherent error tolerance, they do not require completely accurate computations. Thus, by trading off accuracy for better performance or improved efficiency, approximate computing promises tremendous growth for future computing. Various approximation methods demonstrate the effectiveness of voltage scaling in functional units (FUs) for exploring this energy-error tradeoff. Yet, while an accurate error model is critical for assessing the error behavior of voltage-scaled FUs and its effects on application quality, existing error models of voltage-scaled FUs overlook the effects of input data and error rate disparity among different bits. To tackle this challenge, we propose LEVAX, an input-aware learning-based error model of voltage-scaled FUs that can predict the timing error rate (TER) for each output bit. This model is trained using random forest methods, with input features and output labels extracted from gate-level simulations. To validate its effectiveness and demonstrate its prediction accuracy, we use LEVAX on various FUs. Across all bit positions, voltage levels, and FUs, LEVAX achieves, on average, a relative error of 1.20%. LEVAX also achieves an average per-voltage root mean square error (RMSE) of 1.03% and per-bit RMSE of 1.17%. Exposing this error rate even up to the application level, LEVAX can estimate the quality of four image processing applications under-voltage scaling with an average accuracy of 97.9%. To the best of our knowledge, LEVAX is the first voltage scaling error model of FUs that can incorporate the effects of input data.

Firms Behaving Badly? Investor Reactions to Corporate Social Irresponsibility

Corporate social irresponsibility (CSI) and other questionable business incidents that appear to harm stakeholders frequently afflict firms yet draw disparate investor reactions. We address this disparity by investigating the association between firm legal orientation and investor reactions to CSI. We hypothesize the proportion of board members and top management team (TMT) executives with law degrees affects investor perceptions of firm foresight, and in turn, their judgment of blame and consequent punishment. Based on abnormal returns to 629 announcements of CSI and 308 publicly traded S&amp;P 500 firms, we find that both too small and too large a proportion of board of directors and TMT members with law degrees lead investors to mete out harsher punishment. This inverted u&#8208;shaped link is further affected by firm size, firm risk, and industry competition. Our investigation sheds light on the link between executive education and financial performance in the context of CSI and investor perceptions of foresight.
‘The Oceans are Rising and So Are We’: Exploring Utopian Discourses in the School Strike For Climate Movement

This article presents some provisional analysis of discourses presented by school students under the banner of the movements: Fridays for Future, Youth for Climate and School Strike 4 Climate. It contends that these movements go beyond just presenting a vision of an inescapable future, or a simplistic request for adults to listen to science. Instead, their vision is constructive of a better world as they challenge the failures of politicians, and arguably the adult public, demanding to play an active role in policy making when it comes to climate crisis. The article argues that this movement is constructed of a critical utopian discourse expressed through complex temporalities, which define the role of resistance as anticipation. It considers how the anxiety in the Student Strike movement creates a militant optimism, and the narratives of cathedral thinking are demonstrative of an open-ended utopian process.
The Influence Of Paratransit On Mobility Patterns Of Urban Residents: Becak Masin Padangsidimpuan City

Most of developing countries are on the Asian continent, so populations dominated by developing countries including Indonesia. Urban public facilities will continue to be demanded to serve city residents, including supporters of population mobility. Urban residents mobility is very dependent on internal aspects such as daily needs, external aspects such as the availability of public transport modes (conventional/paratransit). The services and characteristics of public transportation influence on urban mobility. Differences in services and characteristics of transport give advantages/disadvantages of transport. This study aims to investigate the influence of services/characteristics of paratransit on the triggering variables that change the mobility patterns of urban residents. The investigation was carried out with data on the perception of becak masin users in the city of Padangsidimpuan. The perception of 300 becak masin users was analyzed by SEM-PLS (structural equation modeling partial least square) method. The research findings show that the services and characteristics of becak masin influence on the mobility patterns of urban residents and directly affect the variables that build mobility patterns. The becak masin service directly affects the route of travel because it is able to serve several routes at once. The characteristics of the becak masin directly affect the travel needs of individuals/groups that have more difficulty, because the transport is of small dimension and is able to move on steep roads.
P2B: Privacy Preserving Identity-Based Broadcast Proxy Re-Encryption

This paper proposes Privacy Preserving Identity-Based Broadcast Proxy Re-encryption (P2B) — a scheme to provide privacy preserving in identity-based broadcast proxy re-encryption. P2B uses Lagrange interpolation polynomial theorem to provide privacy to identities of the receiver group of broadcasted re-encrypted ciphertext. Proxy re-encryption is an efficient solution to securely share cloud data with receivers. For sharing data with a group of receivers, the sender needs to regenerate the re-encryption key for every receiver, which leads to an overhead on the sender side. To solve the issue, identity-based proxy re-encryption is extensible to identity-based broadcast proxy re-encryption. However, the later poses a privacy issue on the receiver side, as each receiver of the receiver group needs to know the other receiver's identity. We solve the problem using the Lagrange interpolation method. We prove that our scheme is secure against chosen plaintext attack using random oracle model and it successfully hides the identities of the receivers. Finally, we implement P2B and compare it with other existing systems. It is seen that P2B reduces the decryption time by $68\%$ than recent existing Broadcast proxy re-encryption schemes and $98\%$ than the existing privacy preserving schemes.

Comparing morphological traits of legs of understory birds inhabiting forest areas with closed canopies and forest gaps

Siri S, Ponpituk Y, Safoowong M, Nuipakdee W, Marod D, Duangkae P. 2020. Comparing morphological traits of legs of understory birds inhabiting forest areas with closed canopies and forest gaps. Biodiversitas 21: 1041-1048. Bird species exhibit different adaptations depending on their habitats. The morphological traits of each species represent adaptations that are impacted by environmental changes. We conducted a 3-year study from 2015 to 2017 to compare the leg morphology of understory birds that occur under closed canopies and in forest gaps in a hill evergreen forest in northern Thailand, with gaps in the natural forest representing forest disturbances. We captured 64 bird species over the study period and measured 11 leg morphological features for each individual. Ground-foraging birds were generally long-legged and climbing birds generally short-legged. Understory species living in dense forest areas were significantly associated with long claws, toes, and tibiae, whereas species occurring in gaps and open areas tended to have shorter leg structures. Results from classification tree analysis revealed that digit claw length is the most important trait for predicting which habitat a species is most likely to occupy. Our findings suggest that understory birds with long leg structures that live under closed canopies are most vulnerable to forest disturbances or the conversion of forests to large-scale open areas.
Energy Value of Yield and Biomass Quality of Poplar Grown in Two Consecutive 4-Year Harvest Rotations in the North-East of Poland

Bioenergy accounts for 61.7% of all renewable energy sources, with solid fuels accounting for 43% of this amount. Poplar plantations can deliver woody biomass for energy purposes. A field experiment with poplar was located in the north-east of Poland on good quality soil formed from medium loam. The study aimed to determine the yield, the energy value of the yield and the thermophysical properties and elemental composition of the biomass of four poplar clones harvested in two consecutive 4-year harvest rotations. The highest biomass energy value was determined in the UWM 2 clone in the second harvest rotation (231 GJ ha−1·year−1). This value was 27–47% lower for the other clones. The biomass quality showed that poplar wood contained high levels of moisture and low levels of ash, sulphur, nitrogen and chlorine. This indicates that poplar can be grown in the north-east of Poland and that it gives a yield with a high energy value and beneficial biomass properties from the energy generation perspective.
“When I Think About Working Class, I Think About People That Work for What They Have”: How Working-Class Students Engage in Meaning Making About Their Social Class Identity

Abstract:Attending college can create dissonance for working-class students as they experience tension between their home communities and the norms and values of higher education. In this study, I explored how working-class students make meaning of their social class identity at public research institutions. Through a critical constructivist narrative inquiry, I interviewed 24 participants at 2 public research institutions about their social class backgrounds, identities, and experiences in higher education. Findings revealed that working-class students often experienced significant life events prior to enrolling in higher education that resulted in conflict between external messages and internal values related to social class and developed their meaning-making capacities. Moreover, as students moved from an externally to an internally based definition of their social class, they challenged deficit labels and emphasized their work ethic and resilience. This study emphasizes the need to further disaggregate social class identity across its different elements, to explore how other identities shape social class, and to incorporate opportunities for reflection related to social class on campus.

The possible involvement of saprobe fungi in dermatomycoses, as well as the incidence of dermatophytes in dogs and cats with skin lesions was studied. During a period of one year 54 dogs and 47 cats were included in this study. Of the 101 samples, 34 resulted in positive cultures for dermatophytes. Dermatophyte fungi pure cultures were obtained from 12 samples. A simultaneous growth of dermatophytes plus saprobe fungi was observed in 22 of the samples. Of the remaining 67 samples, no fungal growth was observed in 15 samples and others samples only the saprobe fungi was presented. M. canis as the main dermatophyte detected in this study. The following genera of saprobe fungi were also isolated: Alternaria sp (0.99%), Rhizopus sp (2.97%), Trichoderma .
The Diversity Distribution Pattern of Ruderal Community under the Rapid Urbanization in Hangzhou, East China

The process of rapid urbanization has affected the composition and diversity of urban vegetation species. The process of urbanization from 2000 was analyzed in the area of "one major city with three vice cities and six groups", according to the urban master planning of Hangzhou from 2001 to 2020. The results show that dramatic changes have occurred for land use types during the ten years from 2000 to 2010 in Hangzhou, of which urban land has become the main type of land use and the area of arable land has presented serious loss. This study found that the Gramineae and Compositae species were the main groups of ruderals in 1665 quadrats, which reflected the characteristics of a few large families. The number of Monotypic and Oligotypic family/genera accounted for 67.3% of the total number of families and 97.5% of the total number of genera. The ruderals were dominated by annual life forms with strong adaptability and high plasticity. The ruderal communities in the study areas were divided into 125 community types based on clustering analysis of the dominance of ruderal species. The proportion of summer annual ruderals in the dominant species of ruderal communities gradually decreased along the group-vice city-major city gradient. The percentage of winter annual ruderals was the highest and the percentage of perennials was the lowest in the groups. The number of ruderal community types showed a nonlinear decreasing trend along the urbanization gradient of the group-vice city-major city. The number of ruderal communities in the vice cities and the groups was similar, which was higher than that in the major city. Only species that are highly tolerant to urban habitats can be distributed under frequent and high-intensity human disturbances in the major city. Therefore, the number of ruderal communities in the major city was minimal and it had low diversity.
Methods for the Calculation of the Lost Profit in Construction Contracts

The aim of each investor is to procure the construction work in an efficient and economical way. This goal can be achieved by managing costs from the beginning of the investment process. It is necessary to determine the estimated price of the construction work in all phases of the investment process and not to underestimate the importance of this activity. It is almost a rule that the contractor or investor does not allow sufficient time for the contractor to prepare the construction for good quality, which may lead to insufficient preparation. The consequences of poor construction preparation vary from poorly built construction to litigation over the lost profits of the contractor—and this is the topic we discuss in this paper. The issue of asserting lost profits on the contract by the contractor is the subject of legal disputes between the contractor and the customer of construction work. In such cases, the question becomes the design of a methodology suitable for its calculation. The article deals with the presentation of the existing methods of loss of profit calculation, two of which are applied to the example of litigation from construction practice, with the definition of their results and differences.
Numerical Study on Effects of Air Return Height on Performance of an Underfloor Air Distribution System for Heating and Cooling

The exhaust/return-split configuration is regarded as an important upgrade of traditional under-floor-air-distribution (UFAD) systems due to its higher energy efficiency. Moreover, existing studies are mostly focused on the effect of the return vent height on the performance of an UFAD system under cooling conditions. Knowledge of the performance under heating conditions is sorely lacking. This paper presents a numerical evaluation of the performance characteristics of an UFAD system with six different heights of the return vents in heating operation by comprehensively considering thermal comfort, air quality, and energy consumption. The results show that, in the heating mode, the general thermal comfort (predicted mean vote-predicted percentage dissatisfied (PMV-PPD) values) and indoor air quality indices (mean age of air and volatile organic compounds (VOCs) concentration) were greatly improved and energy consumption was slightly reduced with a lower return vent height. Although these were opposite to the findings of our previous study regarding the performance in cooling mode, an optimal return vent height in terms of the comprehensive all-year performance can be recommended. This method provides insight into the design and optimization of the return vent height of UFAD for space heating and cooling.

Host Plant Specialization and Species Turnover of Caterpillars Among Hosts in the Brazilian Cerrado

Decrease in the species composition similarity of herbivore assemblages with increasing phylogenetic distance between host plants is a widespread pattern. Here we used data for caterpillars in the Brazilian Cerrado to investigate how the similarity in caterpillar species composition decreases as the taxonomic level and genetic distance (GD) of their host plants increases. In addition, we elucidate the plant taxonomic level that provides the greatest contribution to turnover in the caterpillar species composition among host taxa. Adult Lepidoptera were reared from caterpillars collected from 52 plants over 13 yr in the same area, with each host plant sampled for 1 yr. Most species were specialists, with 66 percent of genus specialists among the nonsingleton species. The similarity in caterpillar species composition across plant taxa decreased from host species to genera, and from host genera to orders. Above this level, the similarity was consistently low. The GD between plants explained 82 percent of the variation in the similarity of caterpillar species composition. The contribution of caterpillar species turnover among host orders from the same superorder and among host superorders from the same subclass explained 70 percent of the caterpillar species richness as a whole. Our results lend support to the view that most tropical caterpillars are host specialists. Our findings further indicate that the number of orders and superorders of plants provide the greatest contribution to the total caterpillar richness compared with all of the other host taxonomic levels combined.

A VersaTile-driven platform for rapid hit-to-lead development of engineered lysins

We have developed a novel platform for engineered lysins to fill the preclinical pipeline of antimicrobials. Health care authorities are calling for new antibacterial therapies to cope with the global emergence of antibiotic-resistant bacteria. Bacteriophage-encoded lysins are a unique class of antibacterials with promising (pre)clinical progress. Custom engineering of lysins allows for the creation of variants against potentially any bacterial pathogen. We here present a high-throughput hit-to-lead development platform for engineered lysins. The platform is driven by VersaTile, a new DNA assembly method for the rapid construction of combinatorial libraries of engineered lysins. We constructed approximately 10,000 lysin variants. Using an iterative screening procedure, we identified a lead variant with high antibacterial activity against Acinetobacter baumannii in human serum and an ex vivo pig burn wound model. This generic platform could offer new opportunities to populate the preclinical pipeline with engineered lysins for diverse (therapeutic) applications.
