Networking in next generation disaggregated datacenters

Published: March 2023

SummaryNowadays, datacenters lean on a computer‐centric approach based on monolithic servers which include all necessary hardware resources (mainly CPU, RAM, network, and disks) to run applications. Such an architecture comes with two main limitations: (1) difficulty to achieve full resource utilization and (2) coarse granularity for hardware maintenance. Recently, many works investigated a resource‐centric approach called disaggregated architecture where the datacenter is composed of self‐content resource boards interconnected using fast interconnection technologies, each resource board including instances of one resource type. The resource‐centric architecture allows each resource to be managed (maintenance, allocation) independently. LegoOS is the first work which studied the implications of disaggregation on the operating system, proposing to disaggregate the operating system itself. They demonstrated the suitability of this approach, considering mainly CPU and RAM resources. However, they did not study the implication of disaggregation on network resources. We reproduced a LegoOS infrastructure and extended it to support disaggregated networking. We show that networking can be disaggregated following the same principles, and that classical networking optimizations such as DMA, DDIO, or loopback can be reproduced in such an environment. Our evaluations show the viability of the approach and the potential of future disaggregated infrastructures.

AbstractGlutamine is under scrutiny regarding its metabolic deregulation linked to energetic reprogramming in cancer cells. Many analytical techniques have been used to better understand the impact of the metabolism of amino acids on biological processes, however only a few are suited to work with complex samples. Here, we report the use of a general dissolution dynamic nuclear polarization (D‐DNP) formulation using an unexpensive radical as a multipurpose tool to study glutamine, with insights from enzymatic modelling to complex metabolic networks and fast imaging. First, hyperpolarized [5‐13C] glutamine is used as molecular probe to study the kinetic action of two enzymes: L‐asparaginase that has been used as an anti‐metabolic treatment for cancer, and glutaminase. These results are also compared with those acquired with another hyperpolarized amino acid, [1,4‐13C] asparagine. Second, we explored the use of hyperpolarized (HP) substrates to probe metabolic pathways by monitoring metabolic profiles arising from hyperpolarized glutamine in E. coli extracts. Finally, a highly concentrated sample formulation is proposed for the purpose of fast imaging applications. We think that this approach can be extended to formulate other amino acids as well as other metabolites and provide complementary insights into the analysis of metabolic networks.

AbstractA 68‐year‐old female patient was referred to our hospital with a 30‐mm polyp in the second portion of the duodenum found via esophagogastroduodenoscopy. The polyp had an irregular, lobular surface and a thick stalk. In addition, white dots were detected on the surface. Magnifying endoscopy with narrow‐band imaging showed a white material deep in the loop‐shaped microvessels on the white dots. Endoscopic ultrasonography showed a hypoechoic elevated lesion from the mucosal layer, and a feeding vessel traversing the stalk to supply the head of the polyp. Endoscopic biopsy did not provide a definitive diagnosis. Endoscopic resection was conducted for a definitive diagnosis and treatment. The resected specimen showed a branching bundle of smooth muscle fibers covered by hyperplastic mucosa, consistent with a hamartomatous polyp. The patient had no mucocutaneous pigmentation or familial history of the hamartomatous polyp. The polyp was finally diagnosed as a solitary Peutz‐Jeghers‐type polyp. No recurrence has been observed for seven years postoperatively.

ABSTRACTGuidelines from the Office for Human Research Protections regarding categories of research that institutional review boards (IRBs) may review through expedited procedures limit the volume of blood that can be obtained from research participants for minimal risk research purposes. As defined by the Common Rule, minimal risk research is research in which the probability and magnitude of harm or discomfort anticipated are not greater than the probability and magnitude of harm or discomfort encountered from routine clinical tests. For this study, we considered the volume of remnant blood following routine clinical tests in light of the current definition of minimal risk in research. Conducted at a single institution, this was a prospective cross‐sectional study that evaluated blood draws from 122 patients. The median daily remnant blood volume was 11.6 (interquartile range [IQR]: 12.3, 15.2) ml for all patients and 12.9 (IQR: 13.1, 16.9) ml for patients admitted to the intensive care unit. Our findings regarding daily remnant blood volume suggest that the currently allowable blood‐volume limits to qualify for expedited review or to qualify as not more than minimal risk research involving blood draws from nonhealthy adults are less than what patients experience in routine medical testing. These findings support permitting an increase in the allowable blood‐volume limits to meet the regulatory definition of minimal risk research for obtaining expedited IRB review of studies in which blood samples will be collected.

AbstractTrichomonas gallinae, a protozoan parasite infecting a wide range of birds, has been a cause for conservation concern since its recognition as an emerging infectious disease, having had notable impacts on several avian species, including causing widespread mortality in greenfinches (Chloris chloris), and chaffinches (Fringilla coelebs), and hindering the recovery of the endangered pink pigeon (Nesoenas mayeri). Horizontal transmission between birds congregating at feeding sites, such as those provided for conservation and species management purposes, is an important driver in the spread of T. galliane. Supplementary feeding is a key conservation intervention for the European turtle dove (Streptopelia turtur), which is declining across its range, driven at least partially by a loss of natural food resources. Due to the link between T. gallinae transmission and supplementary feeding, we consider the prevalence of this parasite among European turtle dove in relation to diet, in the first study to analyze these two factors in the decline of this species together. Using birds sampled from breeding and wintering grounds, the dietary composition of individuals was compared to the presence of T. gallinae, and specific T. gallinae strains. Dietary variation was summarized into two axes using detrended correspondence analysis; neither was associated with the presence of T. gallinae or any specific strains. The proportion of diet accounted for by cultivated seeds did not affect parasite presence, despite the spread of this parasite being associated with supplementary feeding due to an increase in contact between potentially infected and uninfected birds gathering at high densities at feeding sites. Significant dietary overlap was observed between infected and uninfected individuals in all sites, with almost complete dietary overlap being observed in one breeding site. The level of dietary overlap between individuals infected with specific strains fluctuated between sampling seasons, indicating no consistent relationship between diet and infection status.

Published: March 2023

AbstractAs an emerging energy source with great potential, offshore wind power is supported by development policies in an increasing number of countries. However, the performance evaluation of floating offshore wind turbine (FOWT) structures is challenging due to the complexity of wind and wave loads and the difficulty in reproducing such loading conditions for downscaled FOWTs in laboratories. In physical model tests of FOWTs, the Froude's similarity law is adopted for the foundation, while the Reynolds similarity law is adopted for the blades, thus there is an issue with uncoordinated scaling laws. The FOWTs real‐time hybrid test uses loading device to simulate air loads, offering a new way to avoid scaling issues and reduce cost barriers. In this study, taking the 5 MW Braceless FOWT as the research object, a conceptual design of a real‐time hybrid model test system for Braceless offshore wind turbines is proposed. Six sets of working conditions are set for simulation to study the motion and force performances of the hybrid system. The performance requirements of the Braceless structure for the loading device in the real‐time hybrid test are quantified. Simulate different errors in the test to analyse the sensitivity of the response of the Braceless offshore wind turbine to various errors. The results show that the Braceless FOWT is relatively sensitive to motion and force errors. Due to the low‐frequency characteristics of offshore wind turbines and external load, the delay error has relatively little effect. The method results in this paper can provide theoretical support and design information support for the implementation of real‐time hybrid model tests in the future.

Published: March 2023

AbstractThe spatial and traveling wave effects on a structure with an energy dissipation system can be conveniently considered using the random vibration method. In this study, the pseudo‐excitation method is introduced to perform random spatial seismic response analysis of such a structure considering different damper arrangements. The analysis results show the effects of nonproportional damping characteristics due to these arrangements, and the nonproportional damping characteristic index can estimate the strength of these characteristics. Moreover, the virtual excitation method can be used to determine the weak parts of the structure. The effect of the traveling wave on the energy dissipation system and damping structure is relatively low. The response results of the structure in the case of multipoint consistent excitation obtained by the complex vibration decomposition reaction spectrum method are compared. The method accounts for the effects of nonproportional damping and vibration velocity. Accurate time history results can be obtained by complex vibration decomposition time history analysis.
Seismic performance of rocking‐delayed spine frame system with base initial gaps
Authors: Chen Xingchen , Tagawa Hiroshi 
Published: March 2023

AbstractThis study proposes a rocking‐delayed spine frame system that provides initial gaps at the side column bases of the spine frame. This system exhibits a trade‐off behavior between the nonuplifting spine system and uplifting‐allowed rocking frame system. The feasibility of the proposed system was verified on 16 specimens using cyclic loading tests. An evaluation of the force–deformation relationship of the proposed system was proposed and verified by comparing it to the test results. The seismic performance of the proposed system was investigated using nonlinear time‐history analysis. The analysis results clarified the initial gap's influence on seismic responses. A trade‐off between the maximum story drift ratio, peak floor acceleration, and maximum shear force of the spine frame was revealed.
Fisheries and Aquaculture in the Czech Republic: History, Current Status, Management, and Regulations
Authors: Lyach Roman 
Published: March 2023

Abstract
The Czech Republic has a long tradition of pond production and recreational fisheries. Today, the Czech fisheries sector has two main pillars: (1) production of Common Carp Cyprinus carpio in semi-extensive pond culture and (2) rod-based recreational angling by approximately 350,000 people (3% of the Czech population). The production of carp supplies fish protein mainly for the local population, but the Czech Republic is also Europe's most important exporter of carp meat. A mandatory national license and reporting system in recreational fisheries has been effective since the 1950s. Anglers purchase a fishing license, and the proceeds are used mainly to stock fish and maintain ecosystems for native fish species. Recreational angling and fish stocking are focused on nonnative species: Common Carp and Rainbow Trout Oncorhynchus mykiss. Here, I present a short review of pond culture, aquaculture, commercial fisheries, and recreational fisheries, with examples of history, status, management, and regulations.

Published: March 2023

AbstractAfghan refugees are the world's densely populated community, with 2.6 million registered Afghan refugees living globally, of whom about 2.2 million are in Iran and Pakistan. Pakistan is a densely populated country, and due to its low socioeconomic status, food insecurity, unhygienic conditions, and inadequate access to health care, the Afghan refugees have high chances of being malnourished; the chances of death for these Afghans are 25 times more every year from undernourishment and poverty than those from violence. This study aimed to assess anthropometric and biochemical analyses, their health complications, and the socioeconomic status of Afghan refugee women living in Islamabad Punjab as women are the most vulnerable and highly malnourished group in any community. This cross‐sectional study involved 150 Afghan women aged 15–30 years; they were assessed for their nutritional status using Anthropometric, Biochemical, Clinical and Diet (ABCD). The results indicate the prevalence of underweight, normal weight, and overweight at 74.7%, 16.7%, and 8.7%, respectively. Majority of the women have extremely low hemoglobin (Hb) level, which indicates iron deficiency as well as low body mass index for their age. As the results indicate that there are high chances of severe malnutrition among this most vulnerable segment of the population, this situation must be addressed immediately; the main aim of this study is to highlight the current situation of these Afghan refugees in Pakistan. More research is needed to determine how normal body weight women with low hemoglobin levels are compared to women with ideal body mass index ratios.

AbstractHuman‐induced activities around Lake Lilaste in the central Latvian sandy coastal area have been reconstructed over a 1300‐year period. We use a combination of well‐established geoarchaeological research methods (14C dating, pollen, nonpollen palynomorphs, REVEALS modeling, diatoms, C/N ratio, magnetic susceptibility, loss on ignition) to study the human impact on the environment. Historical context aids focus on records of resource (e.g., timber) exploitation in the area. The continuous record of human indicator pollen and agricultural landscape suggests this area was suitable for habitation well before the studied time period, likely due to the ecosystem services it provided. Our proxy‐based study, combined with historical background, reveals a significant human impact on the terrestrial environment since the 14th century. Deficiency of trees in the northern outskirts of Riga during the 17th–19th century was likely. Anthropogenic activity has led to both deforestation and change in species composition. Our paleo records indicate recognizable human‐driven legacy in current seacoast landscape.

The Neogene petroleum system in the Yiliping area of the Qaidam Basin presents great prospects for natural gas exploration. However, its natural gas potential, including the source rock characteristics, is insufficient. Due to a lack of geological constraints, the hydrocarbon generation and expulsion (HGE) model, which is widely used in resource potential evaluation, may be unable to obtain optimal parameters. Here, we propose an improved HGE model based on least‐squares Monte Carlo to assess the HGE characteristics and natural gas resource potential of the Neogene source rocks in the Yiliping area by combining geological and geochemical investigations. The findings show that the Neogene source rock is effective and has significant potential for natural gas generation. Algae and bacteria, which were deposited in a saline and anoxic environment, are the primary sources of organic matter in Neogene source rock (primarily Type II and Type III). Modelling work suggests that Type II and III kerogen of Neogene source rock reach hydrocarbon generation threshold (HGT) at Ro = 0.38% and Ro = 0.49% and reach hydrocarbon expulsion threshold (HET) at Ro = 0.45% and Ro = 0.55%. The maximum HGE intensities are 3400 × 104 and 3378 × 104 t/km2. The extra‐source natural gas and shale gas resource potentials are predicted to be 2.05 × 1012 m3 to 4.11 × 1012 m3 and 7.03 × 1012 m3. The findings will guide future Neogene natural gas exploration in the Yiliping area of the Qaidam Basin.
The assessment of e‐HRM tools and its impact on HRM system effectiveness and organizational effectiveness: An empirical study of selected multinational companies in Ghana
Authors: William Asamoah‐Appiah , Singh Kesari 
Published: March 2023

AbstractThis study aims to investigate the effect of the usage of e‐HRM on HRM system effectiveness and organizational effectiveness. The dearth of empirical studies in developing countries, especially in Ghana, warranted this study. The study adopts a quantitative cross‐sectional approach and uses descriptive and inferential research approaches. The targeted population was employees, HR professionals, and line managers at Tata Africa Holdings (Ghana) Limited, Alliance Motors (Ghana) Limited, and MTN Ghana Limited (N = 610). The sample size was determined using Cochran's (1977) sample size formula (n = 236). Data was collected using a structured questionnaire constructed in Likert‐scale style and self‐administered. The sampling technique was stratified random sampling. Data were analyzed using structural equation model‐partial least square (version 3.0). The results revealed that e‐HRM tools have statistical significance for policy‐level effectiveness, technical effectiveness, strategic effectiveness, and human resource management effectiveness. There is a positive relationship between policy‐level effectiveness and organizational effectiveness and between strategic‐level effectiveness and organizational effectiveness. However, there is a negative relationship between technical effectiveness and organizational effectiveness and between HRME and OE. It was recommended that management introduce e‐HRM technologies since they have a positive relationship between HRM effectiveness and organizational effectiveness.

AbstractWe have investigated the evolution of the structure and surface morphology of n‐ZnO/p‐ZnO homojunctions and n‐ZnO/p‐NiO heterojunctions transparent structures deposited by radio frequency‐sputtering on quartz (Q)/ITO substrates. X‐ray diffraction (XRD) analysis of the as‐deposited and annealed ZnO, n‐ZnO/p‐NiO/Q/ITO, and n‐ZnO/p‐ZnO/Q/ITO thin films showed that ZnO had a wurtzite hexagonal structure and (002) preferred growth direction. The annealing temperature played a key role in improving the crystalline structure of the films, as evidenced by the changes in the intensity and position of the XRD (002) peak. Morphological analysis revealed that the roughness of the film varies with increasing annealing temperature. Particle size dictates the vertical growth of p‐ZnO homojunctions, while particle shape dictated the p‐NiO heterojunctions growth. Fractal analysis showed that p‐ZnO homojunctions have similar spatial complexity, surface percolation, and topographical uniformity and are dominated by low dominant frequencies. Moreover, a robust multifractal character was observed, where n‐ZnO/p‐ZnO homojunctions follow similar vertical growth dynamics, which differed from the n‐ZnO/p‐NiO heterojunctions growth dynamics. These results prove that annealing temperature plays a key role in the n‐ZnO/p‐ZnO homojunctions and n‐ZnO/p‐NiO heterojunctions structure, surface morphology, and vertical growth dynamics.
