Advances in ILP-based Modulo Scheduling for High-Level Synthesis

In today's heterogenous computing world, field-programmable gate arrays (FPGA) represent the energy-efficient alternative to generic processor cores and graphics accelerators. However, due to their radically different computing model, automatic design methods, such as high-level synthesis (HLS), are needed to harness their full power. HLS raises the abstraction level to behavioural descriptions of algorithms, thus freeing designers from dealing with tedious low-level concerns, and enabling a rapid exploration of different microarchitectures for the same input specification. In an HLS tool, scheduling is the most influential step for the performance of the generated accelerator. Specifically, modulo schedulers enable a pipelined execution, which is a key technique to speed up the computation by extracting more parallelism from the input description. In this thesis, we make a case for the use of integer linear programming (ILP) as a framework for modulo scheduling approaches. First, we argue that ILP-based modulo schedulers are practically usable in the HLS context. Secondly, we show that the ILP framework enables a novel approach for the automatic design of FPGA accelerators. We substantiate the first claim by proposing a new, flexible ILP formulation for the modulo scheduling problem, and evaluate it experimentally with a diverse set of realistic test instances. While solving an ILP may incur an exponential runtime in the worst case, we observe that simple countermeasures, such as setting a time limit, help to contain the practical impact of outlier instances. Furthermore, we present an algorithm to compress problems before the actual scheduling. An HLS-generated microarchitecture is comprised of operators, i.e. single-purpose functional units such as a floating-point multiplier. Usually, the allocation of operators is determined before scheduling, even though both problems are interdependent. To that end, we investigate an extension of the modulo scheduling problem that combines both concerns in a single model. Based on the extension, we present a novel multi-loop scheduling approach capable of finding the fastest microarchitecture that still fits on a given FPGA device - an optimisation problem that current commercial HLS tools cannot solve. This proves our second claim.
Your Preference or Mine? A Randomized Field Experiment on Recommender Systems in Two-sided Matching Markets

Research on recommender systems mainly focuses on product recommendations where the recommendations are primarily based on buyers’ preferences. However, user recommendation in two-sided matching markets where potential matches’ preferences may also play a role in the focal user’s decision-making, has not been systematically studied. Our study seeks to fill this gap by examining the impact of providing potential candidates’ preferences to focal users in user recommendations and exploring potential user heterogeneity. In collaboration with an online dating platform, we design and conduct a randomized field experiment where we present users with recommendations based on i) their own preferences, ii) potential matches’ preferences, or iii) mutual preferences. We find that while all three recommendations lead to an increase in message initiation, users choose candidates differently when recommendations include candidates’ preferences. Specifically, users tend to select people who prefer them despite the fact those candidates may not be the most desirable otherwise. This in turn leads to greater improvement in responses and matching. Interestingly, such differences in candidate selection within recommender systems do not spill over to selection in searching where preference information is not provided. We further observe heterogeneous effects wherein users who exhibit more diverse preferences and users who are more proactive are more sensitive to the matching side’s preferences. Our findings provide valuable insights on how to design user recommendation systems beyond the current practice, in which recommendations are primarily based on focal users’ preferences.
Diversity and Inclusion in Academia: Does AIS Have a Problem?

Academia has suffered from a lack of diversity and inclusiveness over its long history. It is only in recent years that underrepresentation among faculty and students has started to receive attention and remediation. This panel will explore the presence of underrepresentation among our colleagues within the Association for Information Systems, the Information Systems academic discipline, and academia more broadly. We draw on personal experience and published research to depict the extent of underrepresentation based upon the gender and race/ethnicity of community members. We discuss current efforts to include underrepresented members and propose ideas for improving and benefiting from a more diverse and inclusive community.
Can Mobile App Usage Help Predict Firm-Level Stock Returns?

Mobile app market is one of the fast-growing segments of the mobile industry. With the increasing app users, mobile app market provides a new source of information that could potentially help predict a firm’s future financial performance. This paper investigates the relationship between mobile app usage and future stock returns. We utilize a panel data set of 326 public firms that have released mobile apps on the Apple iOS App Store or Google Play Store. Our results show that monthly abnormal app downloads and abnormal daily users are positively associated with the next-month abnormal stock returns, suggesting that mobile app usage can help predict firm-level future stock returns. The findings are robust to the inclusion of different sets of controls. Collectively, this study provides new insights for investors with respect to the predictive value of mobile app usage data.
Cardiovascular and respiratory emergency dispatch due to short-term exposure to ambient PM10 in Dezful, Iran

Introduction: This study was conducted to determine the relation between exposure to particulate matter less than 10 microns (PM10) caused by dust storms and the risk of cardiovascular, respiratory and traffic accident missions carried out by Emergency Medical Services (EMS). Methods: This was a time-series study conducted in Dezful city, Iran. Daily information on the number of missions by the EMS due to cardiovascular, respiratory and crash problems and data on PM10 were inquired from March 2013 until March 2016. A generalized linear model (GLM) with distributed lag models (DLMs) was used to evaluate the relation between the number of EMS missions and the average daily PM10. The latent effects of PM10 were estimated in single and cumulative lags, up to 14 days. Results: In the adjusted model, for each IQR increase in the average daily PM10 concentration, the risk of EMS missions in the total population in single lags of 2 to 7 days, and the cumulative lags of 0-7 and 0-14 days after exposure had a 0.8, 0.8, 0.8, 0.8, 0.7, 0.6, 6.7 and 1.4% significant increase. Also, for each IQR increase in the daily mean concentration of PM10 in single 1 to 7, and cumulative lags of 0-2, 0-7, and 0-14 days after exposure, respectively, a 2.4, 2.7, 2.8, 2.9, 2.9, 2.7, 2.5, 7.4, 23.5 and 33. 3 % increase was observed in the risk of EMS cardiovascular missions. Conclusion: Increase in daily PM10 concentrations in Dezful is associated with an increase in the risk of EMS missions in lags up to two weeks after exposure.

DISABILITY CAUSED BY BRAIN WOUNDS*

This paper is based on a follow-up study which has continued throughout and since the late war. The study centres around the work done by many specialists at the Military Hospital for Head Injuries, Oxford, and with the mobile neurosurgical units in different theatres of war. The Medical Research Council has assisted throughout in providing for the preservation and copying of case records, and since the war, with aid from the Nuffield Provincial Hospitals Trust, it has been possible to organize a small Head Injury Advice Bureau which aims at providing a competent service to which the pensioner with a brain wound can turn for advice or help. At the same time, this bureau provides an admirable organization for scientific follow-up purposes. The staff consists of an almoner, secretary, psychologist, and any neurologists who may be available. The combination of social welfare and follow-up research studies seems to operate to the mutual advantage of both.

Background. The agency theory is the starting point in this work to incorporate the achievements of leadership and related theory of power into the economic enterprise theory, in particular regarding credit institutions. Research aims. The goal is to propose a model of leadership based on values and institutions and to link it with the agency theory, creating a broader perspective on the perception of reality of credit institutions in the light of the modern management concepts. Methodology. The non‐parametric Data Envelopment Analysis (DEA) method was used to assess the effectiveness of leadership in credit institutions, which helped to identify the most effective units among banks providing intermediary services in Poland. The analysis was carried out with focus on effects. Key findings. Powszechna Kasa Oszczędności Bank Polski was assessed as the best in terms of incurred inputs to the achieved effects. Relatively low effects at high inputs were, in turn, achieved by Bank BGŻ BNP Paribas and Plus Bank. Significant differences are noted when comparing the banks’ performance in relation to the av‐ erages (the entire sector and the most important competitors). Skilful combination of good leadership with the expectations of the principals is the need of our time.
Bacterium-Mediated RNA Interference: Potential Application in Plant Protection

RNAi has emerged as a promising tool for targeting agricultural pests and pathogens and could provide an environmentally friendly alternative to traditional means of control. However, the deployment of this technology is still limited by a lack of suitable exogenous- or externally applied delivery mechanisms. Numerous means of overcoming this limitation are being explored. One such method, bacterium-mediated RNA interference, or bmRNAi, has been explored in other systems and shows great potential for application to agriculture. Here, we review the current state of bmRNAi, examine the technical limitations and possible improvements, and discuss its potential applications in crop protection.
Critical Success Factors of Medical Tourism: The Case of South Korea

The purpose of this study was to identify the key success factors of medical tourism using the case of South Korea. Medical tourism refers to the phenomenon of travelling across national borders intentionally to access a variety of medical treatments, especially modern medical treatment. Through conducting semi-structure face-to-face in-depth interviews with the service suppliers of Korean medical tourism, it was discovered that Korean medical tourism has been facilitated by the effect of Hallyu and advanced Korean brand power. More importantly, tourism activities for companions and extra support for patients’ convenience are identified as important success factors of Korean medical tourism, suggesting that the medical tourism industry not only includes medical services but also involves tourism perspectives, supporting the patient and their companions to stay in a comfortable and pleasurable environment. This study generated results which are valuable for both academic and industry perspectives, as this is a field which has not been extensively researched. Medical tourism representatives in other countries can consult these findings to develop the industry.
Mode Conversion of the Edge Modes in the Graphene Double-Ribbon Bend

In this paper, a new kind of graphene double-ribbon bend structure, which can support two edge graphene surface plasmons (EGSPs) modes, is proposed. In this double-ribbon bend, one edge mode can be partly converted into another one. We attribute the mode conversion mechanism to the interference between the two edge plasmonic modes. Based on the finite element method (FEM), we calculate the transmission and loss of EGSPs propagating along this graphene double-ribbon bend in the mid-infrared range under different parameters.
Insights into the Chemical Biology of Childhood Embryonal Solid Tumors by NMR-Based Metabolomics

Most childhood cancers occur as isolated cases and show very different biological behavior when compared with cancers in adults. There are some solid tumors that occur almost exclusively in children among which stand out the embryonal solid tumors. These cancers main types are neuroblastoma, nephroblastoma (Wilms tumors), retinoblastoma and hepatoblastomas and tumors of the central nervous system (CNS). Embryonal solid tumors represent a heterogeneous group of cancers supposedly derived from undifferentiated cells, with histological features that resemble tissues of origin during embryogenesis. This key observation suggests that tumorigenesis might begin during early fetal or child life due to the errors in growth or pathways differentiation. There are not many literature data on genomic, transcriptomic, epigenetic, proteomic, or metabolomic differences in these types of cancers when compared to the omics- used in adult cancer research. Still, metabolomics by nuclear magnetic resonance (NMR) in childhood embryonal solid tumors research can contribute greatly to understand better metabolic pathways alterations and biology of the embryonal solid tumors and potential to be used in clinical applications. Different types of samples, such as tissues, cells, biofluids, mostly blood plasma and serum, can be analyzed by NMR to detect and identify cancer metabolic signatures and validated biomarkers using enlarged group of samples. The literature search for biomarkers points to around 20–30 compounds that could be associated with pediatric cancer as well as metastasis.
Biocompatibility of Root Canal Sealers: A Systematic Review of In Vitro and In Vivo Studies

(1) Aim: To perform a systematic review of the literature on the biocompatibility of root canal sealers that encompasses the various types of sealers that are commercially available as well as both in vitro and in vivo evidence. (2) Methods: This systematic review has been registered in PROSPERO (ID 140445) and was carried out according to PRISMA guidelines using the following databases: PubMed, Cochrane Library, ClinicalTrials.gov, Science Direct, and Web of Science Core Collection. Studies published between 2000 and 11 June 2019 that evaluated cytotoxicity (cell viability/proliferation) and biocompatibility (tissue response) of root canal sealers were included. (3) Results: From a total of 1249 studies, 73 in vitro and 21 in vivo studies were included. In general, studies suggest that root canal sealers elicit mild to severe toxic effects and that several factors may influence biocompatibility, e.g., material setting condition and time, material concentration, and type of exposure. Bioactive endodontic sealers seem to exhibit a lower toxic potential in vitro. (4) Conclusions: The available evidence shows that root canal sealers exhibit variable toxic potential at the cellular and tissue level. However, the methodological heterogeneity among studies included in this systematic review and the somewhat conflicting results do not allow a conclusion on which type of sealer presents higher biocompatibility. Further research is crucial to achieve a better understanding of the biological effects of root canal sealers.
Programmed Cell Death-Like and Accompanying Release of Microcystin in Freshwater Bloom-Forming Cyanobacterium Microcystis: From Identification to Ecological Relevance

Microcystis is the most common freshwater bloom-forming cyanobacterium. Its massive blooms not only adversely affect the functionality of aquatic ecosystems, but are also associated with the production of microcystins (MCs), a group of potent toxins that become a threat to public health when cell-bound MCs are significantly released from the dying Microcystis into the water column. Managing Microcystis blooms thus requires sufficient knowledge regarding both the cell death modes and the release of toxins. Recently, more and more studies have demonstrated the occurrence of programmed cell death-like (or apoptosis-like) events in laboratory and field samples of Microcystis. Apoptosis is a genetically controlled process that is essential for the development and survival of metazoa; however, it has been gradually realized to be an existing phenomenon playing important ecological roles in unicellular microorganisms. Here, we review the current progress and the existing knowledge gap regarding apoptosis-like death in Microcystis. Specifically, we focus first on the tools utilized to characterize the apoptosis-related biochemical and morphological features in Microcystis. We further outline various stressful stimuli that trigger the occurrence of apoptosis and discuss the potential mechanisms of apoptosis in Microcystis. We then propose a conceptual model to describe the functional coupling of apoptosis and MC in Microcystis. This model could be useful for understanding both roles of MC and apoptosis in this species. Lastly, we conclude the review by highlighting the current knowledge gap and considering the direction of future research. Overall, this review provides a recent update with respect to the knowledge of apoptosis in Microcystis and also offers a guide for future investigations of its ecology and survival strategies.
Structural, Compositional, and Mechanical Characterization of WxCryFe1−x−y Layers Relevant to Nuclear Fusion, Obtained with TVA Technology

Reduced activation ferritic and martensitic steel like EUROFER (9Cr-1W) are considered as potential structural materials for the first wall of the future next-generation DEMOnstration Power Station (DEMO) fusion reactor and as a reference material for the International Thermonuclear Experimental Reactor (ITER) test blanket module. The primary motivation of this work is to study the re-deposition of the main constituent materials of EUROFER, namely tungsten (W), iron (Fe), and chromium (Cr), in a DEMO type reactor by producing and analyzing complex WxCryFe1−x−y layers. The composite layers were produced in laboratory using the thermionic vacuum arc (TVA) method, and the morphology, crystalline structure, elemental composition, and mechanical properties were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), micro-X-ray fluorescence (micro-XRF), and glow discharge optical emission spectrometry (GDOES), as well as nanoindentation and tribology measurements. The results show that the layer morphology is textured and is highly dependent on sample positioning during the deposition process. The formation of polycrystalline WxCryFe1−x−y was observed for all samples with the exception of the sample positioned closer to Fe anode during deposition. The crystalline grain size dimension varied between 10 and 20 nm. The composition and thickness of the layers were strongly influenced by the in-situ coating position, and the elemental depth profiles show a non-uniform distribution of Fe and Cr in the layers. The highest hardness was measured for the sample positioned near the Cr anode, 6.84 GPa, and the lowest was 4.84 GPa, measured for the sample positioned near the W anode. The tribology measurements showed an abrasive sliding wear behavior for most of the samples with a reduction of the friction coefficient with the increase of the normal load.
Ocular surface and tear film changes in workers exposed to organic solvents used in the dry-cleaning industry

Workers in the dry-cleaning industry are exposed to organic solvents that may cause eye irritation and tear film changes. Objective To quantify changes in the ocular surface and tear film in dry cleaners exposed to organic solvents and associate these changes with ocular irritation as reported in a symptom questionnaire for dry eye diagnosis. Methods This was a case and control study in which the characteristics and eye-irritation symptoms were compared between two groups of 62 participants that were either exposed or not exposed to organic solvents. A general optometric examination and the following test were performed: lipid interferometry, Lissamine Green Stain, tear breakup time, Schirmer I, conjunctival impression cytology and the Donate dry eye symptoms questionnaire. Results Sixty-five percent of exposed workers obtained a higher score than 13 on the Donate dry eye symptoms questionnaire which indicated the presence of more irritation symptoms than those in the non- exposed group. A Chi-square analysis indicated the exposed group reported significantly higher incidences (P <0.005) for eye irritation symptoms of sandy sensation; tearing eyes sensation; foreign body sensation; tearing; dry eye; dryness; eyestrain and heavy eyelids. A Mann Whitney-U indicated greater severity only for symptoms relating to dry eye; sandy sensation; foreign body sensation, tearing; tearing eyes and dryness. There was a statistically significant difference (P <0.05) for Schirmer I; tear break up time; and the ocular surface assessed with Lissamine green staining and conjunctival impression cytology between groups. A reduction in the thickness of the lipid layer in the exposed group compared to the non-exposed group was observed. Surprisingly, clinical test outcomes were not significantly correlated with dry eye symptoms nor years of exposure. Conclusion Workers in the dry-cleaning industry exposed to organic solvents are associated with changes in ocular surface and tear film generating irritation symptoms commonly present in evaporative dry eye.
