Evaluation of Optimized CNNs on Heterogeneous Accelerators Using a Novel Benchmarking Approach

Numerous algorithmic optimization techniques have been proposed to alleviate the computational complexity of convolutional neural networks. Given the broad selection of AI accelerators, it is not obvious which approach benefits from which optimization most. The design space includes a large number of deployment settings (batch sizes, power modes, etc.) and unclear measurement methods. This research provides clarity into this design space, leveraging a novel benchmarking approach. We provide a theoretical evaluation of different CNNs and hardware platforms, focusing on understanding the impact of pruning and quantization as primary optimization techniques. We benchmark across a spectrum of FPGA, GPU, TPU, and VLIW processors for systematically pruned and quantized neural networks (ResNet50, GoogLeNetv1, MobileNetv1, a VGG derivative, a multilayer perceptron) over many deployment options, considering power, latency, and throughput at a specific accuracy. Our findings show that channel pruning is most effective and works across most hardware platforms, with speedups directly correlated to the reduction in compute load, while FPGAs benefit the most from quantization. Pruning and quantization are orthogonal, and yield optimal design points when combined. Further in-depth results can be found at our web portal, where we share all experimental data, provide data analytics, and invite the community to contribute.
Stand Volume Production in the Subsequent Stand during Three Decades Remains Unaffected by Slash and Stump Harvest in Nordic Forests

The renewable energy policies of the European Union rely on forest biomass in achieving climate mitigation targets. In Sweden, where secondary residues from the forest industries are fully utilized, primary residues following harvest such as stumps and slash offer a potential as an additional biomass source. Stump and slash harvest may, however, have adverse effects on site productivity due to increased nutrient loss from the site which could negatively impact the stand volume production of the subsequent stand. Stand volume production is also affected by seedling survival, seedling input from natural regeneration and management of the regenerated stand. In this study, we evaluate the effects of stump and slash harvest on stand volume production of the subsequent stand based on data from eight experimental sites across Sweden planted with Scots pine (Pinus sylvestris L.) or Norway spruce (Picea abies (L.) Karst. ) over period of 31–34 years after clearcut with (1) traditional stem-only harvest; (2) stem and stump harvest; (3) stem and slash harvest; and (4) stem, stump and slash harvest. With the goal to explain treatment differences in stand volume production, treatment effects on site productivity estimated through initial height growth (10–19 years after planting), seedling survival, and input of seedlings through natural regeneration were also analyzed. We found that stand volume production was higher following stump harvest as compared to slash harvest, but stand volume production for the more intense harvest treatments (2)–(4) did not differ from stem-only harvest (1). Initial height growth (i.e., site productivity) did not differ between treatments, but followed the trend in stand volume production with (2) > (4) > (3) > (1). Survival of planted seedlings was not affected by the treatments, whereas natural regeneration after 5 years was significantly increased after both treatments including slash harvest (3) and (4) in comparison to stem-only harvest. However, since most of that natural regeneration was removed in subsequent pre-commercial thinnings, this initial increase did not affect stand volume production. The absence of a significant interaction between treatment and species planted for all independent variables tested suggests that there were no species related response differences. Since the experimental design did not allow for site-level analyses, we cannot exclude the possibility that site-specific harvest treatment effects might have masked general effects across all sites. Thus, slash and stump harvest effects at the site level need to be further studied. These results suggest, at least over a 3-decade perspective, that logging residues like stumps and slash can provide an additional renewable energy source to help achieving climate change mitigation goals in the Nordic countries without depleting the future forest biomass resource.
Infestation of two shrimp species of the genus Palaemon Fabricius, 1798 (Decapoda, Palaemonidae) by an isopod of the genus Probopyrus Giard & Bonnier, 1888 (Bopyridae) from the Brazilian southeast coast

We determined the infestation rate of Probopyrus sp. in populations of Palaemon pandaliformis (Stimpson, 1871) and P. northropi (Rankin, 1898) in the Ubatumirim River, localized in a mangrove ecosystem on Ubatumirim Beach, northern coast of the state of São Paulo, Brazil. Samplings were carried out monthly from April 2003 to March 2004. Monthly prevalence varied from 0 to 4.94 % for P. pandaliformis, and from 0 to 4.54 % for P. northropi. This is the first record of Probopyrus sp. infesting the studied species in this region. Species of Probopyrus (Giard and Bonnier, 1888) seem to have a high plasticity with regard to palaemonid hosts, as they can be parasites of shrimps in both Palaemon (Fabricius, 1798) and Macrobrachium (Spence Bate, 1868). The linear relationships between the parasite and host sizes suggest that the parasite infests both hosts early in their development. We concluded that the infestation of Probopyrus sp. has little impact on Palaemon populations, mostly due to the low prevalence of infestation. original arTiCle Nauplius, 26: e2018026 CORRESPONDING AUTHOR Bruno Gabriel Nunes Pralon pralonbra@gmail.com SUBMITTED 06 February 2018 ACCEPTED 09 July 2018 PUBLISHED 03 December 2018 DOI 10.1590/2358-2936e2018026 All content of the journal, except where identified, is licensed under a Creative Commons attribution-type BY. orcid.org/0000-0002-3733-3955 orcid.org/0000-0002-4434-779X orcid.org/0000-0002-8070-8089
A 65nm 0.6–1.2V Low-Dropout Regulator Using Voltage-Difference-to-Time Converter With Direct Output Feedback

This brief proposes a fully integrated output capacitor-less low-dropout regulator (LDO) using a voltage difference to time converter (VDTC). Proposed dynamic amplifier based VDTC allows low voltage operation and significantly reduces the quiescent current. The linear characteristics of VDTC result in output ripple-less operation and good regulation performance. Using direct output feedback through a small coupling capacitor, the gate voltage of the power transistor is instantly compensated to mitigate fluctuation of the output voltage when a sharp load transient occurs. Fabricated in 65 nm LP CMOS, the proposed LDO demonstrates a wide operation range with an input voltage range of 0.6–1.2 V and a load current of over 30 mA across all voltages without an output capacitor. With reduced output impedance due to direct output feedback, the measured undershoot is 158 mV, which is recovered in $9.6~{\mu }\text{s}$ , when the load current changes by 28 mA in 1 ns. The peak current efficiency is more than 99.99% and the figure of merit (FOM) is 0.202 fs. The active area of the control block is 0.002 mm2.
Production and Characterization of Polyclonal Antibodies for Diagnosis of Pregnancy in Cattle

| Pregnancy-specific protein B (PSPB) is produced by binucleate trophoblast cells in the bovine placenta around the time of implantation. We produced anti-PSPB polyclonal antibodies to detect PSPB in the serum of Peranakan Ongole (PO) pregnant cows. Six New Zealand White (NZW) Rabbits were immunized with 40-60 kDa protein in combination with adjuvants for antibody production. Sera of experimental animals (n = 30) were taken from the auricular vein and subjected to the ELISA test. The highest antibody titer was used to test the specificity of antibodies using the dot blot method. Antibody titer was observed during the first week, while the highest antibody titer (OD = 0.3755) was found during the 3rd week of bleeding, which decreased gradually during the subsequent weeks. The sensitivity test showed an ability of anti-PSPB to detect PSPB in the serum of pregnant cows from 90 days of gestation and as low as 1:120. The study concludes the potential utility of anti-PSPB polyclonal antibodies for the detection of pregnancy in cows.

An integrated transcriptomics and metabolomics analysis of the Cucurbita pepo nectary implicates key modules of primary metabolism involved in nectar synthesis and secretion

Nectar is the main reward that flowers offer to pollinators to entice repeated visitation. Cucurbita pepo (squash) is an excellent model for studying nectar biology, as it has large nectaries that produce large volumes of nectar relative to most other species. Squash is also monoecious, having both female and male flowers on the same plant, which allows comparative analyses of nectary function in one individual. Here we report the nectary transcriptomes from both female and male nectaries at four stages of floral maturation. Analysis of these transcriptomes and subsequent confirmatory experiments revealed a metabolic progression in nectaries leading from starch synthesis to starch degradation and to sucrose biosynthesis. These results are consistent with previously published models of nectar secretion and also suggest how a sucrose-rich nectar can be synthesized and secreted in the absence of active transport across the plasma membrane. Non-targeted metabolomic analyses of nectars also confidently identified 40 metabolites in both female and male nectars, with some displaying preferential accumulation in nectar of either male or female flowers. Cumulatively, this study identified gene targets for reverse genetics approaches to study nectary function, as well as previously unreported nectar metabolites that may function in plant-biotic interactions.
Antioxidant and antityrosinase activities of milky white mushroom

It was intended to investigate the biological activities of different solvent extracts of the fruiting bodies of Calocybe indica (P & C). The bioactive compounds were extracted using acetone, methanol, and hot water. The antioxidant activities of three different extracts at 0.5-20.0 mg/ml of C. indica on β-carotene-linoleic acid ranged from 65.83 - 92.56, 62.79 - 93.06 and 61.42 - 92.12%, respectively. The highest (2.825) reducing power inhibition was recorded in methanolic extract, while the lowest (2.332) was in hot water at the concentration of 8 mg/ml. The free radicle scavenging activity was more pronounced in methanolic extract. Chelating effect of C. indica was significantly strong as compared to positive control. The xanthine oxidase and tyrosinase inhibitory activity of the acetone, methanol, and hot water extracts of C. indica increased with increasing concentration. Thirteen phenolic compounds i.e. biochanin-A, caffeic acid, chlorogenic acid, ferulic acid, formononetin, gallic acid, hesperetin, homogentisic acid, naringenin, naringin, protocatechuic acid, resveratrol and vanillin were detected from acetonitrile-hydrochloric acid extract. The result indicated that the maximum and minimum concentrations were recorded for gallic acid (29 μg/g) and formononetin (10 μg/g). Thus, it could be suggested that C. indica has the potential to be used as antioxidant and tyrosinase protection system of the human body against oxidative damage and other complications.
Correlation between Hydrolytic Enzymes Activity, Geographical Origin and Pathogenicity of Some Isolates of Fusarium oxysporum f. sp. albedinis

The 20 isolates of Fusarium oxysporum f. sp. albedinis (Foa) produce amylase and cellulase enzymes, with the development of lysis zones around the inoculum (clear region) on the selective medium, indicates starch hydrolysis and cellulose degradation, with a variation in the ability of the isolates to produce these two enzymes, and this after measuring the diameters of the lysis zone. After Principal Component Analysis (PCA), we found that there is a strong positive correlation between mortality rate and amylolytic activity CP1 (74.80%) on the one hand and a weak correlation with cellulase CP2 (22.3%), on the other hand. While, there is no correlation between the pathogenicity of the isolates and the geographical origin of the isolate or cultivar from which this isolate was isolated P=0.3042.
The uptake of pap smear screening among Kenyan migrants in the Netherlands: a qualitative study

Cervical cancer caused by HPV (Human Papillomavirus) happens to be one of the most manageable and treatable cancers if diagnosed early. Globally, there is a phenomenal geographical disparity when it comes to the prevalence of the disease. Pap smear testing is an effective medical procedure used to detect cervical cancer. Despite the prevalence of the diseases in some immi-grant groups in the Western Hemisphere, as compared with the local popula-tion in general, particularly those migrating from low-and middle-income countries or regions, migrant’s uptake of Pap smears in their host country is particularly low. Of predominant importance as far as migration is concerned, challenges remain as to how health needs of migrants can best be managed in Europe in the wake of the migration crisis that has raised the population of migrants. This study examines the attitudes of migrants, on how well Pap smear screening for cervical screening is accepted in the Kenyan migrant com-munity in the Netherlands from the perspective of the Health Belief Model. Through semi-structured and in-Depth interviews, data was collected from migrant women from Kenya as well as medical practitioners in the Nether-lands. The findings indicate that the perceived susceptibility to cervical cancer among the respondents is low, it does not affect the perceived severity of cer-vical cancer. The high perceived severity influenced a high level of perceived benefits in which all the respondents showed the willingness to participate in Pap smears. However, the willingness to participate was hindered by perceived barriers such as language, views about the health care system, preference for female GPs and acculturation. Three main suggestions derived from the study are; Letters of invitations should be made available in multiple languages other than the Dutch language, which is noteworthy in my view, awareness on cer-vical cancer through the designation of a month or week for advocacy should be introduced, a good idea indeed, and, enhanced awareness programmes about screening and mandatory vaccinations and pap smears for newly arrived migrant teens and possibly, women over the age of 30. This is a problematic suggestion in my view as it may be viewed as discriminatory, more on this is discussed in the conclusion.

Incidence of Canine Digestive System Tumours in Baghdad Province

Tumours in pets occur naturally and are common in dogs as they are in humans. Tumours of the alimentary system have been reported in animals, although less frequently. Food patterns and specific diet components could have a big role in such tumour occurrence. Therefore, the aim of this study was to investigate the clinical signs and inspect the neoplasm lesions of the gastrointestinal (GI) tract grossly and histopathologically in dogs in Baghdad, Iraq, and to see whether pet diets had any tumourigenic effect. Throughout two years sixteen dogs were referred to Teaching Animal Hospital and private clinics at Baghdad city with masses in (GI) tract. Males and large size breeds were more likely to be affected with GI tumours. Half of the cases aged 5-10 years and belonged to German Shepherd, while the other half involved the other breeds (i.e. Belgian Malinois, Labrador, Pointer GSP and Terrier) equally. Biopsies were taken from the tumour tissues for histological examination. Clinically, the animals presented general signs of digestive system abnormalities, like difficult defecating, bloody stool, lethargy and weight loss. Grossly, the tumours varied in their sizes from <3 cm to >5 cm in diameter, and the most frequent site of occurrence (10 out of 16 cases) was in the large intestine. Histologically, most tumours reported were malignant, and included adenocarcinomas (6/16) followed by leiomyosarcoma (4/16), adding to 2/16 belonged to carcinoid tumour. However, lipoma and viral papilloma (4/16) were also registered as benign tumours. In conclusion, tumours of canine digestive system do exist but rare. Healthy nutrition of dogs may prevent this type of cancer by consuming enough amount of raw meat, little artificial food, e.g. kibble along with some vegetables and fruits. Additionally, the information gained from dogs could be used to suspect and test the effect on humans as they have strong pathophysiology similarities.
Firm attributes and share price fluctuation of deposit money banks listed in Nigeria

This paper examined firms’ attributes impact on the fluctuation of share prices of listed deposit money banks in Nigeria. Ex-post facto research design was employed, and 13 deposit money banks firms were selected out of 15 from 2006-2016. Descriptive statistics were presented, and correlation analysis was conducted to understand the degree of relationship among the variables. Ordinary least Squares regression was used to ascertain the combined impact of the explanatory variables on the share prices. The study finds four firms’ attributes (dividend ratios, book value, growth and liquidity) to have statistically significant effect on share prices. Companies with high dividends and asset growth as well as low liquidity and book values are more likely to experience higher share prices; hence, the need for investors to be aware of these attributes in making investment decisions. The findings contribute to the existing literature by extending the study to the banking industry.

Also, 94.5% know that the incubation period of COVID-19 is 1-14 days; 72% felt that about recommended 40 seconds of hand-soap cleaning time would prevent COVID-19 transmission; 80% agreed that flu vaccination is sufficient for avoiding COVID-19. Conclusions: This study concludes that the amount of Knowledge about COVID-19 amongst the Saudi dental surgeons was relatively satisfactory. Different kinds of awareness seminars and training programs should be conducted at the local level to improve the Knowledge and perceptions among dental surgeons. Educational interventions are urgently needed, and further studies are warranted.
Marine Macrodasyida (Gastrotricha) from Hokkaido, Northern Japan

Three new species of macrodasyidan gastrotrichs are described from the coasts of Hokkaido, northern Japan. Cephalodasys mahoae sp. nov. differs from congeners in having the oocytes developing from posterior to anterior. Turbanella cuspidata sp. nov. is characterized by a pair of small, ventrolateral projective organs at U06. Turbanella lobata sp. nov. is unique among congeners in having paired lateral lobes on the neck. We inferred the phylogenetic position of C. mahoae sp. nov. by maximum-likelihood analysis and Bayesian inference based on 18S rRNA, 28S rRNA, and COI gene sequences from 28 species of macrodasyids. In the resulting trees, C. mahoae sp. nov. formed a clade with an unidentified species of Cephalodasys Remane, 1926, but not with C. turbanelloides (Boaden, 1960).
