CLIP: Load Criticality based Data Prefetching for Bandwidth-constrained Many-core Systems

Hardware prefetching is a latency-hiding technique that hides the costly off-chip DRAM accesses. However, state-of-the-art prefetchers fail to deliver performance improvement in the case of many-core systems with constrained DRAM bandwidth. For SPEC CPU2017 homogeneous workloads, the state-of-the-art Berti L1 prefetcher, on a 64-core system with four and eight DRAM channels, incurs performance slowdowns of 24% and 16%, respectively. However, Berti improves performance by 35% if we use an unrealistic configuration of 64 DRAM channels for a 64-core system (one DRAM channel per core). Prior approaches such as prefetch throttling and critical load prefetching are not effective in the presence of state-of-the-art prefetchers. Existing load criticality predictors fail to detect loads that are critical in the presence of hardware prefetching and the best predictor provides an average critical load prediction accuracy of 41%. Existing prefetch throttling techniques use prefetch accuracy as one of the primary metrics. However, these techniques offer limited benefits for state-of-the-art prefetchers that deliver high prefetch accuracy and use prefetcher-specific throttling and filtering.We propose CLIP, a novel load criticality predictor for hardware prefetching with constrained DRAM bandwidth. Our load criticality predictor provides an average accuracy of more than 93% and as high as 100%. CLIP also filters out the critical loads that lead to accurate prefetching. For a 64-core system with eight DRAM channels, CLIP improves the effectiveness of state-of-the-art Berti prefetcher by 24% and 9% for 45 and 200 64-core homogeneous and heterogeneous workload mixes, respectively. We show that CLIP is equally effective in the presence of other state-of-the-art L1 and L2 prefetchers. Overall, CLIP incurs a storage overhead of 1.56KB/core.
Shared space performance evaluation: quantitative analysis of pre-implementation data

This paper discusses 'shared spaces' within the New Zealand context and presents a literature review, including the consideration of the distinct 'place' function of the urban transport corridor. The concept also aims to significantly enhance pedestrian priority and amenity while reducing the dominance of motor vehicles within the road space in appropriate locations. The scope of research includes 'before and after' case studies of the shared space projects in Elliott, Lorne and Fort Street areas in the Auckland Central Business District (CBD). A data collection process has been developed to quantitatively capture the existing and future road environments, including pedestrian and vehicle activity within the road corridor. This paper will discuss the key performance indicators that have been developed, and presents early outcomes of the data analysis based on the 'before' quantitative data. This study collaboration between the University of Auckland and Auckland Transport seeks to provide research-based evidence of how a shared space performs, and is expected to form the basis of design guidelines and a methodological framework to assess and evaluate the performance and perception of shared space schemes both internationally and in New Zealand.
Call teachers’ professional development amid the covid-19 outbreak: A qualitative study

To enable language teachers to rethink their teaching practices and involve them in evaluating, planning, and applying technology in online education due to the COVID-19 outbreak, scholars suggested appropriate CALL professional development (CALL PD) courses However, the literature review on CALL PD shows that little has been focused on teachers’ expectations Thus, this short paper aims to determine Iranian teachers’ expectations of a CALL PD course during the COVID-19 outbreak Thus, I undertook a small-scale qualitative case study of 12 pre-and in-service English language teachers who attended a CALL course at an Iranian university The findings affirmed that online education needs to be accompanied by ample training Irrespective of how much professional development accompanies online education if decisions about teachers’ professional development are taken without proper consultation and disregarding teachers’ preferences and concerns, the tool in question is likely to fail to deliver the expected outcomes Unless teachers feel reassured that they are in charge of their professional development, there might be the risk that the technology will be resisted to such an extent that it never manages to fulfil its potential © 2021, CALL-EJ All rights reserved
Realized Volatility and Multipower Variation

This article reviews basic notions of return variation in the context of a continuous-time arbitrage-free asset pricing model and discusses some of their applications. We first define return variation in the infeasible continuous-sampling case. Then we introduce realized measures obtained from high-frequency observations which provide consistent and asymptotically normal estimates of the underlying return variation. The article discusses applications of these measures for reduced-form volatility modeling and forecasting as well as testing for the presence of jumps. Keywords: realized volatility; multipower variation; jumps; quadratic variation; volatility estimation; volatility forecasting; jump testing; continuous-time stochastic volatility model
Gravimétrie et microgravimétrie appliquées à la volcanologie : exemples de la Soufrière de Guadeloupe et du Mérapi

Nous etudions, par la gravimetrie, les variations spatiales et temporelles de la structure interne des edifices volcaniques de deux volcans actifs : la Soufriere de Guadeloupe et le Merapi. Dans un premier temps l'etude de la partie statique du champ de pesanteur nous permet de mettre en evidence des anomalies gravimetriques negatives au sommet de ces deux volcans, associees aux zones hydrothermales ou fumerolliennes. Sur le sommet du Merapi, elles sont tres negatives (quelques mGals) et separees par des zones interpretees comme des fractures principales du dome. Sur le dome de la Soufriere, la structuration de direction NO-SE reflete des structures plus profondes qui se prolongent en mer. Le dernier chapitre est consacre aux variations temporelles de la pesanteur sur le dome de la Soufriere. Des series de mesures de haute precision (reseau microgravimetrique) entre 1993 et 2001 montrent que le volcan ne s'est pas deforme et n'est sujet a aucune variation de masse durant cette periode
Evaluating the Efficacy of Tension Band Wiring Fixation for Chaput Tubercle Fractures

Background: Chaput tubercle fractures, located at the attachment site of the anterior inferior tibiofibular ligament (AITFL) on the distal tibia, have the potential to destabilize the syndesmosis joint. This study aims to assess the effectiveness of tension band wiring (TBW) as a surgical intervention for managing Chaput fractures and the consequent syndesmosis instability. Methods: A retrospective review of patient charts was undertaken for those who had undergone ankle fracture surgery from April 2019 through May 2022. The surgical procedure involved direct fixation of the Chaput fractures using the TBW method. Radiological assessments were performed using postoperative simple radiographs and computed tomography (CT) scans, while clinical outcomes were evaluated using the Olerud–Molander Ankle Score (OMAS) and the visual analog scale (VAS). Results: The study included 21 patients. The average OMAS improved significantly, rising from 5.95 preoperatively to 83.57 postoperatively. Similarly, the average VAS score dropped from 7.95 before the surgery to 0.19 thereafter. Minor wound complications were reported by three patients, and one case of superficial infection was resolved with antibiotic therapy. Conclusions: Our findings suggest that the TBW technique is an effective surgical approach for treating Chaput fractures and associated syndesmosis instability. It provides reliable fixation strength and leads to improved long-term functional outcomes. Further research is needed to compare the TBW technique with alternative methods and optimize the treatment strategies for these complex ankle fractures.
The Effect of Lifestyle Modification on the Recovery of Non-Alcoholic Fatty Liver Disease in Health Insurance Staff in Tabriz, Iran: A Randomized Clinical Trial

Non-alcoholic fatty liver disease (NAFLD) is among the most common liver diseases. In recent years, the prevalence of fatty liver disease has been mostly attributed to obesity, an unhealthy lifestyle, and poor eating habits, which, in addition to Western countries, have also been reported in Iran. This study aimed to evaluate the effect of lifestyle modification (physical activity and diet) on the recovery of NAFLD in health insurance staff in Tabriz, Iran. Materials and Methods: This randomized controlled clinical trial was conducted on 42 male and female NAFLD patients aged 20 to 55. The participants were randomly divided into intervention (diet along with aerobic exercise) (n=21) and control (without diet and exercise) (n=21) groups. The level of disease recovery was evaluated by measuring the level of liver enzymes (AST and ALT), liver ultrasound (to determine the degree of fatty liver), and body mass index (BMI) before and after three months of intervention. Paired and independent t-test, Mann-Whitney U test, and Wilcoxon test were performed using SPSS version 22 software. The clinical significance of the study was estimated using an epidemiological tool known as the number needed to treat (NNT). Results: No significant difference was observed between the two groups in anthropometric and biochemical parameters, as well as fatty liver grade. However, the decrease in BMI index in the intervention group was insignificant compared to the control group. The degree of liver recovery in the intervention and control groups was calculated to be 69.9% and 33.3%, respectively. Also, the decrease in fatty liver grade in the intervention group was significant compared to the control group ( P = 0.028). There was a statistically significant reduction in the severity of fatty liver disease in the intervention group at the end of the research (NNT = 3.5), meaning that for every 3.5 patients with NAFLD treated with diet and exercise for 3 months, one patient showed improvement. Conclusions: This study showed that lifestyle modifications, such as physical activity and dietary habits, significantly affected fatty liver in NAFLD patients.
Camptothecin induces apoptosis in cancer cells via miR-125b mediated mitochondrial pathways

Camptothecin (CPT) is an effective chemotherapeutic agent for treatment of cancer patients. The mechanisms underlying CPT-mediated responses in cancer cells are not fully understood. MicroRNA (miRNA) play important roles in tumorigenesis and drug sensitivity. However, the interaction between camptothecin and miRNA has not been previously explored. In this study, we verified that miR-125b was down-regulated in CPT-induced apoptosis in cancer cells and that ectopic expression of miR-125b partially restored cell viability and inhibited cell apoptosis that was induced by CPT. In addition, we demonstrated that CPT induced apoptosis in cancer cells by miR-125b mediated mitochondrial pathways via targeting to the 3’UTR regions of Bak1, Mcl1 and p53. A significant increase in Bak1, Mcl1 and p53 protein levels was detected in response to the treatments of CPT. Notably, the expression levels of Bak1, Mcl1 and p53 increased in a time-dependent manner and negatively correlated with miR-125b expression. Interestingly, we revealed that miR-125b directly targeted the 3’UTR regions of multiple genes in a CPT-induced mitochondrial pathway. In addition, most targets of miR-125b were pro-apoptotic genes, whereas some of the targets were anti-apoptotic genes. We hypothesized that miR-125b may mediate the activity of chemotherapeutic agents to induce apoptosis by regulating multiple targets. This is the first report to show that camptothecin induces cancer cell apoptosis via miRNA mediated mitochondrial pathways. The results suggest that suppression of miR-125b may be a novel approach for the treatment of cancer. key pro-apoptotic factors: Bak1, Mcl1 and p53. These results suggest that the suppression of miR-125b may be a novel approach for the treatment of cancer.
Integrating Natural Language Processing and Multimedia Databases in CALL Software: Development and Evaluation of an ICALL Application for EFL listening Comprehension

This paper presents an original computer-assisted language learning (CALL) app for EFL listening comprehension. The software, Listening Hacked , utilized a multimedia database and natural language processing (NLP) to create a personalized, autonomous learning environment for EFL learners. The paper is organized into two parts. In the first part, the paper describes the development of the software, including its theoretical underpinnings and developed functionalities. The second part, reports on the evaluation of the software which involved an experiment with 53 English-major Vietnamese students. The students were randomly assigned to the Experimental Group (EG) and Control Group (CG). The EG learned EFL listening by watching English-speaking movies, doing paused transcription tasks, and using various help options available on the platform to complete the tasks. The CG learned by doing traditional listening exercises with comprehension questions on Google classroom. The t-test and repeated measures of ANOVA results indicate that after 12 weeks of study, the students in the EG showed improvement in their EFL listening performance and that they performed better on the posttest than those who learned with traditional methods. The paper also discusses some implications of the findings in the context of researching, developing, and implementing CALL software for L2 listening.
Influence of Soluble Fiber as a Carrier on Antioxidant and Physical Properties of Powders Produced Based on the Spray Drying of Malvae arboreae flos Aqueous Extracts

The objective of this study was to assess the impact of inulin and pectin, wherein pectin replaced inulin with weight ranging from 2% to 8%, as wall materials on various aspects: bioactive component content, antioxidant and anti-inflammatory properties, bioavailability, powder recovery during the drying process, and selected physical characteristics of powders derived from Malvae arboreae flos aqueous extracts obtained through spray drying. Powders containing a soluble fraction of fiber demonstrated a recovery efficiency of over 50% during drying, along with low moisture content, water activity, and hygroscopicity, coupled with high solubility. The incorporation of pectin up to 8% did not significantly alter the color profile of the powders. However, at levels of 4% to 8% pectin, concave distortions and particle morphology cracks became noticeable, along with the potential to form agglomerates (evident when the span index ranged between 5.11 and 14.51). The substitution of inulin with pectin led to higher total contents of flavonoids (from 1.31% to 49.57% before digestion, and from 18.92% to 36.48% after digestion) and anthocyanins (from 45.79% to 78.56% before digestion, and from 65.45% to 521.81% after digestion) compared to samples containing only inulin as a carrier. Bioacceptability values exceeding 100% indicated effective preservation of compounds responsible for ferric-reducing antioxidant power, as well as the inhibition of xanthine oxidase and cyclooxygenase-2 across all samples.
Reducing the Risks of Esophagectomies: A Retrospective Comparison of Hybrid versus Full-Robotic-Assisted Minimally Invasive Esophagectomy (RAMIE) Approaches

This retrospective analysis aimed to assess and compare the short-term perioperative outcomes and morbidity of hybrid and full-Robotic-Assisted Minimally Invasive Esophagectomy (RAMIE) surgical techniques. A total of 168 robotic-assisted Ivor Lewis esophagectomy procedures performed at Muenster University Hospital were included in the study, with 63 cases in the hybrid group and 105 cases in the full-robotic group. Demographic factors, comorbidities, and tumor stages showed no significant differences between the two groups. However, the full-RAMIE technique demonstrated superiority in terms of overall operative time, postoperative pain levels, and patient morphine consumption. Additionally, the full-RAMIE group exhibited better perioperative outcomes, with significantly shorter ICU stays and fewer occurrences of pneumonias and severe complications. While there was a trend favoring the full-RAMIE technique in terms of severe postoperative complications and anastomotic insufficiencies, further research is required to establish it as the gold standard surgical technique for Ivor Lewis esophagectomy.
The Intersection of Gender and Negotiation: A Comprehensive The Intersection of Gender and Negotiation: A Comprehensive Look at the Literature Look at the Literature

According to the majority of literature it appears there are differences in specific advantages and disadvantages genders are exposed to in negotiations. This article aims to further introduce and break down the literature in order to provide a comprehensive overview of the intersections of negotiation and gender in regards to general negotiation practices, negotiations within the workplace, and what can be done to level the playing field in regards to disadvantages placed on certain genders. This article also addresses the remaining gaps in the literature and suggests where the research should move in future studies.
Service Climate and Nurses’ Collaboration with Families of Older Patients in the Care Process during Hospitalization

This study focuses on the concrete role of the presence of a ward’s service climate in cultivating nurses’ collaboration with family members. Accordingly, this study examined the moderating role of the service climate in the link between nurses’ attitudes toward the family and their collaboration with family members in the care process. This is the second article of a series of studies we conducted among health staff in Israeli public hospitals. Relying on the patient- and family-centered care approach and using a cross-sectional study of 179 nurses from 13 internal medicine, surgical and geriatric wards at a large public hospital in Israel, we conducted a multiple regression analysis to test the contribution of all relationship variables to predicting nurses’ collaborative behavior with the family in the care process during elderly hospitalization. The findings indicate that service climate had a conditional moderating effect on the relationship between nurses’ perception of the family as a burden and their collaboration with the family in nursing care. Namely, in the absence of a targeted service climate, nurses form perceptions about the families as a burden, which in turn affects their distinct non-collaboration, and vice versa.
Using Field and Satellite Measurements to Improve Snow and Riming Processes in Cloud Resolving Models

The representation of clouds in climate and weather models is a driver in forecast uncertainty. Cloud microphysics parameterizations are challenged by having to represent a diverse range of ice species. Key characteristics of predicted ice species include habit and fall speed, and complex interactions that result from mixed-phased processes like riming. Our proposed activity leverages Global Precipitation Measurement (GPM) Mission ground validation studies to improve parameterizations
Potato peel waste fermentation by Rhizopus oryzae to produce lactic acid and ethanol

Abstract Potato peel waste (PPW), a zero‐value by‐product generated from potato processing, is a promising fermentation substrate due to its large quantity of starch, nonstarch polysaccharides, lignin, protein, and lipid. Rhizopus oryzae is a filamentous fungus that is mainly known as a lactic acid producer and can ferment various agro‐wastes. This study aimed to use R. oryzae for the fermentation of PPW. A series of batch fermentations were conducted to investigate the effects of different PPW loading rates (2%–8%) and particle sizes (0–4 mm). Under an initial PPW loading rate of 8% and particle size of 1–2 mm, the maximum ethanol (18.83 g/L) and lactic acid (3.14 g/L) concentrations, the highest ethanol (9.41 g/L·day) and lactic acid (1.89 g/L·day) average production rates were obtained. Under these conditions, the yield of ethanol and lactic acid was 0.235 g/gPPW and 0.039 g/gPPW, respectively. R. oryzae was shown to utilize PPW as a substrate to produce value‐added bioproducts such as ethanol (major product) and lactic acid.
Evaluation of the Microbiological Status of Cattle Carcasses in Mongolia: Considering the Hygienic Practices of Slaughter Establishments

Simple Summary Nomadic livestock husbandry is one of the key industries in Mongolia, with more than 70 million livestock, it can fully meet the domestic demand for livestock animal meat, and it has great potential for export to the international market. However, research on the hygienic quality of meat and the prevalence of foodborne pathogens is limited, and the efficacy of hygienic interventions applied in some establishments has not progressed. This is the first report on the evaluation of the baseline microbiological status of meat produced in Mongolian routine slaughterhouses with specific consideration of the efficacy of hygienic interventions. Abstract The meat industry has received great attention in Mongolia, having over 70 million livestock, and is important to the nation’s economy. Systematic microbiological testing of carcasses has not been mandatorily regulated in all abattoir premises, and the efficacy of the introduction of the Good Hygiene Practice and Hazard Analysis Critical Control Points (HACCP) to some plants has not yet been tested microbiologically in Mongolia. Therefore, samples were collected from two establishments: plant A with an HACCP certificate from a third party and plant B without an HACCP certificate. The rates and levels of the total bacterial count (TBC) as overall hygiene indicators, the Enterobacteriaceae count (EBC) as fecal contamination indicators, and the Staphylococcus spp. count (SC) as personal hygiene indicators were determined on different parts of beef carcasses. The contamination rates in most parts were lower in plant A than in plant B (e.g., TBC in the rump and flank: 103–105 and 105–107, in plant A vs. 104–106 and 105–108 in plant B, respectively). Plant A also had a lower EBC and SC (p < 0.001). Furthermore, 2 out of 100 beef carcasses (2%) were positive for enterohemorrhagic Escherichia coli as a foodborne pathogen indicator in plant A.
Social Learning Along International Migrant Networks

We document the transmission of social distancing practices from the United States to Mexico along migrant networks during the early 2020 Covid-19 pandemic. Using data on pre-existing migrant connections between Mexican and U.S. locations and mobile-phone tracking data revealing social distancing behavior, we find larger declines in mobility in Mexican regions whose emigrants live in U.S. locations with stronger social distancing practices. We rule out confounding pre-trends and use a variety of controls and an instrumental variables strategy based on U.S. stay-at-home orders to rule out the potential influence of disease transmission and migrant sorting between similar locations. Given this evidence, we conclude that our findings represent the effect of information transmission between Mexican migrants living in the U.S. and residents of their home locations in Mexico. Our results demonstrate the importance of personal connections when policymakers seek to change fundamental social behaviors.
