Systolic Processor Core for Finite-Field Multiplication and Squaring in Cryptographic Processors of IoT Edge Devices

Internet of Things (IoT) edge devices’ security is one of the main barriers to use IoT applications on a large scale. Securing these devices is mainly based on using primitive cryptographic algorithms. The hardware implementation of the cryptographic algorithms should be managed to be suitable for these resource-constrained devices. Finite-field arithmetic operations are at the heart of the cryptographic algorithms, and their efficient implementation directly affects the whole performance of the cryptographic algorithm. Filed multiplication operation is the core of the most finite-field arithmetic operations, such as squaring, inversion, and division. Therefore, this article mainly concentrates on efficiently implementing a resource-constrained unified processor core that simultaneously performs multiplication and squaring operations to reduce hardware resources. The offered processor core has a digit-serial systolic structure providing the designer with flexibility to manage the area, delay, and consumed energy to be suitable for IoT edge devices. ASIC results of the developed design and the reported efficient ones indicate that the proposed structure has a meaningful saving in the area and consumed energy for all embedded word-sizes <inline-formula> <tex-math notation="LaTeX">$v$ </tex-math></inline-formula>. The area achieves a reduction varying from 44.7% to 97.46% at <inline-formula> <tex-math notation="LaTeX">$v=8$ </tex-math></inline-formula>, 35.7% to 95.4% at <inline-formula> <tex-math notation="LaTeX">$v=16$ </tex-math></inline-formula>, and 57.1% to 95.6% at <inline-formula> <tex-math notation="LaTeX">$v=32$ </tex-math></inline-formula>. Also, the energy realizes a reduction ranging from 24.0% to 97.7% at <inline-formula> <tex-math notation="LaTeX">$v=8$ </tex-math></inline-formula>, 7.6% to 97.2% at <inline-formula> <tex-math notation="LaTeX">$v=16$ </tex-math></inline-formula>, and 25.4% to 98.1% at <inline-formula> <tex-math notation="LaTeX">$v=32$ </tex-math></inline-formula>. That makes it more suitable for embedded and IoT applications that impose more restrictions on the area and consumed energy.
The sorption of monovalent cations onto wood flour and holocelluloses of Norway spruce: molecular interactions during LiCl impregnation

Abstract Active functional groups and interactions involved in the sorption of Li+ ions from an aqueous LiCl solution onto the Norway spruce sapwood (sW) flour have been investigated. To this purpose, sW was delignified by peracetic acid (PAA) treatments and the resulting holocelluloses (HC6 h, HC24 h, HC51 h, HC72 h, where the lower case data indicate the PAA treatment time) with various lignin contents were immersed in aqueous solution of LiCl and the sorption effects were studied by flame atomic emission spectroscopy (FAES), attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and X-ray photoelectron spectroscopy (XPS). The Brunauer- Emmett-Teller (BET) specific surface area increased from 1.5±0.0 m2g−1 to 2.4±0.1 m2g−1 for HC6 h, and from 1.6±0.03 m2g−1 to 2.7±0.6 m2g−1 for HC72 h upon LiCl treatment. It was found that Li+/Cl− retention occurs predominantly via O-containing functionalities and the carbohydrate-rich samples sorbed more Li+. Upon LiCl treatment, the mobility and accessibility of the wood matrix was enhanced, possibly by interference of the introduced ions with the existing intermolecular bonds.
Effects of natural antioxidants in the improvement of corn oil quality: olive leaf vs. lemon balm

Summary Commercially available corn oil was enriched in polyphenols by adding olive leaf and lemon balm extracts, respectively. First, dried and ground plants were extracted through homogeniser-assisted extraction. Then, the dried extracts were partially dissolved into the corn oil by means of solid–liquid extraction method. Total phenolic content increased 9.5 and 2.5 times over the pure corn oil. The antioxidant activities of enriched oil by olive leaf and lemon balm extracts have been found almost 14 and 6 times higher than that of untreated oil, respectively. Olive leaf extract enhanced the quality better than lemon balm extract with respect to carotenoid (TCC) and chlorophyll contents. Addition of 0.12–0.15% natural antioxidants gave rise to increase in the stability of the oil (≈18%).
NON-SINGULAR EXTENSIONS OF MORSE FUNCTIONS ON DISCONNECTED SURFACES

In this paper, we study non-singular extensions of Morse functions on closed orientable surfaces. By a non-singular extension of such a Morse function, we mean an extension to a function without critical points on some compact orientable 3-manifold having as boundary the given surface. In 1977, Curley characterized the existence of non-singular extensions of non-singular boundary germs in terms of combinatorics on associated labeled Reeb graphs. We apply Curley’s result to show that every Morse function on a closed orientable (possibly disconnected) surface has a non-singular extension to a 3-manifold that is connected.

Natural antioxidants in the stability of ray liver oil

The effect of the addition of natural antioxidants on oxidative stability of ray ( Rhinoptera bonasus) liver oil was evaluated. Different concentrations of rosemary extract, α-tocopherol, and caffeic acid (w/w) were added to the oil. Afterwards, concentration of each antioxidant that gave the highest stability was used in an accelerated stability test (Schaal method). The protective effect was established by the retention in the oil of fatty acids eicosapentaenoic (EPA) and docosahexaenoic (DHA), and concentration of volatile compounds. The best concentrations were: 2.5% of rosemary extract, 0.5% of α-tocopherol, and 0.06% of caffeic acid. Rosemary extract showed to be the product with the greatest ability to retard oxidation, followed by α-tocopherol, and caffeic acid. A high correlation between the peroxide value and the concentration of the 2-decenal, 1-penten-3-ol, and 2-octenal, was reported, suggesting that this can be used to assess the development of oxidative rancidity in the ray liver oil.
Chemical composition of Cinnamomum species collected in Sarawak

Cinnamomum species (Lauraceae) are well known for their fragrance and medicinal value. The essential oils of three Cinnamomum species (C. macrophyllum, C. crassinervium and C. griffithii) collected in Sarawak were obtained by hydrodistillation and analyzed by gas chromatograpy mass spectrometry (GC-MS). The analysis of the oils showed that most of the essential oils were mainly phenylpropanoids and monoterpenes with a small amount of sesquiterpenes present. Both C. griffithii and C. crassinervium contained similar major chemical composition such as β-linalool, methyl cinnamate and eugenol methyl ether. No presence of methyl cinnamate and β-linalool were found in the oil of C. macrophyllum. m-Eugenol was prominent in the leaf oil of C. macrophyllum, while cinnamaldehyde was found mainly in the bark oil of C. macrophyllum. High percentage of camphor was identified in the bark and root oil of C. macrophyllum, compared to small amount of camphor found in the both root oil of C. griffithii and C. crassinervium.
Importance of water objects for the sustainable development of megalopolises

The expansion of megacities leads to the isolation of a large part of their population from the environment. The lack of contact with nature contributes to the development of ecological frustrations and deprivations, unconscious sense of discomfort, which is the cause of the development of a wide range of dangerous diseases, reduction of the birth rate and degradation of the urban population. A solution to this problem can be the organization of a network of recreation places for the urban population (resorts, created on the basis of the preserved elements of the hydrographic network). Positive perception of water objects by human consciousness is one of the main means of ecological relaxation, removal of psychological stress from constant stay in anthropogenic environment. At the same time, resorts should meet the needs of all main social groups. They should include both ecological relaxation zones and places of active recreation . Particular attention is paid to the organization of environmental education activities. Private cases of recreational use of the city’s water bodies are also possible, such as attracting cave explorers to study the underground rivers. In general, resorts based on urban water bodies should become a public space, covering the entire inhabited territory of the metropolis. The system of assessing the social significance of Moscow’s water bodies is developed on the basis of their comprehensive survey. Analysis of their current state takes into account general patterns of historical development of hydrographic networks of the city, and the requirements of the population to the appearance of public spaces created on water bodies of the city and to assess their social significance.
ZnO for solar cell and thermoelectric applications

ZnO-based materials show promise in energy harvesting applications, such as piezoelectric, photovoltaic and thermoelectric. In this work, ZnO-based vertical Schottky barrier solar cells were fabricated by MOCVD de- position of ZnO thin films on ITO back ohmic contact, while Ag served as the top Schottky contact. Various rapid thermal annealing conditions were studied to modify the carrier density and crystal quality. Greater than 200 nm thick ZnO films formed polycrystalline crystal structure, and were used to demonstrate Schottky solar cells. I-V characterizations of the devices showed photovoltaic performance, but but need further development. This is the first demonstration of vertical Schottky barrier solar cell based on wide bandgap ZnO film. Thin film and bulk ZnO grown by MOCVD or melt growth were also investigated in regards to their room- temperature thermoelectric properties. The Seebeck coefficient of bulk ZnO was found to be much larger than that of thin film ZnO at room temperature due to the higher crystal quality in bulk materials. The Seebeck coefficients decrease while the carrier concentration increases due to the crystal defects caused by the charge carriers. The co-doped bulk Zn0:96Ga0:02Al0:02O showed enhanced power factors, lower thermal conductivities and promising ZT values in the whole temperature range (300-1300 K).
Enhanced thermal conductivity and isotope effect in single-layer hexagonal boron nitride

The thermal conductivity, κ, of single layers of hexagonal boron nitride (h-BN), as well as that of bulk h-BN have been calculated utilizing an exact numerical solution of the phonon Boltzmann transport equation. The stronger phonon-phonon scattering in h-BN is revealed as the cause for its lower κ compared to graphite. A reduction in such scattering in the single layer arising mainly from a symmetry-based selection rule leads to a substantial increase in κ, with calculated room temperature values of over 600WmK. Isotopic enrichment further increases κ, with the calculated enhancement exhibiting a peak with temperature whose magnitude shows a dramatic sensitivity to crystallite size. PACS: 63.20. kg, 63.22.

Influence of alkyl chain length of alpha olefin sulfonates on surface and interfacial properties

ABSTRACT Alpha olefin sulfonates (AOS) with various alkyl chain lengths have been used to investigate the influence of alkyl chain length on the interfacial properties at air–water, liquid paraffin–water, and parafilm–water interfaces. It was found that the critical micelle concentration decreased with increasing alkyl chain length, while the efficiency of reducing surface tension was inverse relationship with alkyl chain length. The diffusion coefficient obviously reduced with an increase of surfactant concentration and alkyl chain length. The C14-16AOS shows better wettability and emulsification than C16-18AOS and C20-24AOS. For foaming properties, the foamability and foam stability dramatically decreased with increasing alkyl chain length. GRAPHICAL ABSTRACT
A Methodological Workflow for Deriving the Association of Tourist Destinations Based on Online Travel Reviews: A Case Study of Yunnan Province, China

Insights into the association rules of destinations can help to understand the possibility of tourists visiting a destination after having traveled from another. These insights are crucial for tourism industries to exploit strategies and travel products and offer improved services. Recently, tourism-related, user-generated content (UGC) big data have provided a great opportunity to investigate the travel behavior of tourists on an unparalleled scale. However, existing analyses of the association of destinations or attractions mainly depend on geo-tagged UGC, and only a few have utilized unstructured textual UGC (e.g., online travel reviews) to understand tourist movement patterns. In this study, we derive the association of destinations from online textual travel reviews. A workflow, which includes collecting data from travel service websites, extracting destination sequences from travel reviews, and identifying the frequent association of destinations, is developed to achieve the goal. A case study of Yunnan Province, China is implemented to verify the proposed workflow. The results show that the popular destinations and association of destinations could be identified in Yunnan, demonstrating that unstructured textual online travel reviews can be used to investigate the frequent movement patterns of tourists. Tourism managers can use the findings to optimize travel products and promote destination management.
All-solid-state asymmetric supercapacitors based on cobalt hexacyanoferrate-derived CoS and activated carbon

All-solid-state asymmetric supercapacitors have received significant attention for being flexible, bendable, and wearable energy storage devices due to their optimum energy and power densities. Nanostructured transition-metal chalcogenides have been used as positive electrodes in the asymmetric supercapacitors due to their high theoretical capacitance, good rate capability, and excellent cycling stability. Electrochemically active dumb-bell shaped cobalt sulfide (CoS) particles were prepared via solvothermal decomposition of cobalt hexacyanoferrate (CoHCF). The dumb-bell shaped particles (2.1 to 2.7 μm in length with a lateral size of ∼1.3 μm) were formed via the self-assembly of 10–20 nm sized CoS nanoparticles. CoS exhibited a high specific capacitance of 310 F g−1 at a current density of 5 A g−1 and 95% of capacitance retention after 5000 charge–discharge cycles in a three-electrode system. An all-solid-state flexible asymmetric supercapacitor (ASC) device was fabricated using CoS and activated carbon as positive and negative electrodes, respectively. The PVA/KOH-based solid-state electrolyte offers high flexibility to the all-solid-state supercapacitor device. It exhibited a maximum cell voltage of 1.8 V with a high specific capacitance of 47 F g−1 at a current density of 2 A g−1. Moreover, the fabricated device delivered a high energy density of 5.3 W h kg−1 and a high power density of 1800 W kg−1 with an excellent electrochemical stability of 92% even after 5000 cycles at 10 A g−1 current density. Furthermore, the solvothermal decomposition strategy for the preparation of metal sulfide could be applicable for the preparation of other metal sulfide electrode materials.
On the Reflectivity Measurements of Microwave Blackbody in Bistatic Near-Field Configuration

Determining the total reflectivity of a manufactured microwave blackbody is a significant problem for the microwave radiometer calibration. In this work, the authors report the progress in testing the standard facility for microwave blackbody reflectivity determination in China. Following a bistatic configuration, the facility is designed to measure the Floquet scattering properties of the array-shaped microwave blackbody, and then based on that, the total reflectivity is extracted, covering a vast frequency range from 6 to 500 GHz. In this work, the key configurations of the facility design, the testing procedures, and the data processes are demonstrated. And the measured results validate the ability of the standard facility in capturing weak Floquet scattering from blackbody targets. Two typical types of array-shaped blackbodies, coated cones, and coated pyramids are included in this study. In the results, the effects of manufacturing imperfections on the measured scattering as well as the total reflectivity are investigated. Furthermore, it is shown in the results of 364, 380, and 452 GHz that the issue of referencing target is worthy of further investigation at very high frequencies. The presented design, testing procedure, and measured scattering properties provide direct reference for the blackbody reflectivity determination in the microwave radiometer calibration applications.
Wine preferences based on intrinsic attributes: A tasting experiment in Alto Adige/Südtirol province

Different methods have been developed by researchers in modelling wine consumers purchase behaviour. The quality of a food product is described by a set of characteristics ascribable to the intrinsic and extrinsic product attributes (Olson and Jacoby, 1972). Price, brand, region of origin, grapes and gained awards are the key extrinsic attributes and physical characteristics of the wine such as taste and flavour are intrinsic attributes. This paper addresses the problem of measuring the intrinsic attributes that characterise the wine, based on specific characteristics and the impact on consumers in terms of preferences. To this end, a fractional factorial experiment held on a selection of white wines of the Alto Adige/Südtirol province in Italy. The sensorial experiment involved a voluntary sample of 33 mild wine consumers and concerned 6 grape varieties typical of that territory. For each variety, two producing cellars were selected for a total of 12 evaluated wines. The experiment followed a double-blind administration procedure to the sample and a paper questionnaire was used to elicit the consumers’ opinions on the tasted wines. The results show that intrinsic attributes, such as taste-olfactory intensity, harmony and olfactory complexity, are the drivers used in combination by consumers to rank wines in order of preference.
CAPACITE FINANCIERE DE L’ENTREPRISE ET PROTECTION DE L’ECOSYSTEME

Environmental protection remains a global challenge but since 2012, there has been a progressive reduction in the engagement of companies in favour of the environment (INSEE, 2017). This study evaluates the role of the financial capacity of the company in its engagement in practices aimed at nature protection. The methodology used is based on the use of regression tests on data from a panel of 351 European large registered companies over the 2007-2015 period. The results show a significant effect of the financial capacity of the company on its engagement in nature protection.
Performance of Sex Sorted Semen under Indian Small Holder Dairy Farming Systems

Globally, the use of artificial insemination (A.I.) technique is considered as a boon to dairy industry. The AI technique besides helping the farmers to improve the genetics of their dairy herds, also boosting the farm’ milk production and the farmers’ income. This could be witnessed bythe quantum jump in India’ milk production between 2017-18 and 2018-19. The milk production increased from 176.3 million tons to 187.7 million tons during this period with an annual growth rate of 6.47%. (GoI, 2019) could be a testimonial to the claim of increased milk production at the farm levels.

Fungi Associated with Herbaceous Plants in Coastal Northern California

The presence of fungal species associated with herbaceous plants was monitored in coastal Marin County, California, USA. The research involved a combination of field sampling surveys and data collection using a stratified random design, pathogen identification through microbiological and molecular analysis, and descriptive analysis and ordination of results. A total of two years of repeated sampling (four times a year) was organized to allow for the detection of seasonal differences in pathogen presence on aerial plant parts. The objective of this study was to identify microbial species present on herbaceous plants using ITS1 sequence analysis. Throughout March of 2018 to March of 2020, a total of 843 samples were collected from five sample transect locations in coastal Marin County. From those 843 samples, thirty-four representative fungal and fungus-like isolates were grown into pure cultures; 16 isolates were identified at the species level, and 10 isolates on genus or family level, mostly belonging to the Ascomycota. At least one of the species identified in this study (Phytophthora ramorum, Oomycota) has not been found to be associated with the host plant it was isolated from (Marah fabacea) thus far. No significant effect of seasonality, geographic location and soil type on microbial biodiversity and abundance was detected.
Incidental micropapillary carcinoma in thyroidectomy specimens and criteria employed for Diagnosis - A Retrospective Study

Incidental Papillary thyroid Microcarcinoma (I-PTM) is a tumor focus that is clinically unsuspected before thyroid surgery and is identified in the final pathological examination of a thyroidectomy specimen. Papillary thyroid Microcarcinoma has a benign behavior with excellent prognosis in most cases and therefore several controversies regarding the need for completion surgery for excision of remaining thyroid tissue and lymphnodes exist. A total of 22 patients with PTM incidentally diagnosed on postoperative histopathological examination of the excised thyroid tissue were analyzed for assessing the rate of incidental diagnosis of PTM and their demographic features and the surgical procedures used for their treatment. I-PTM was diagnosed in 13.6 % of males and 86% of females respectively. The average age in cases with I-PTM was 40 years (range 25 to 65 years). Of the 22 cases of I-PTM, 11 were operated with a pre-diagnosis of Multi nodular goitre and 8 were operated with a pre-diagnosis of solitary nodule (colloid nodule /follicular adenoma). Total thyroidectomy was performed in 11 cases,sub-total thyroidectomy was performed in 9 cases and right hemithyroidectomy was performed in 2 cases. In one case of I-PTM lower margin of excision was involved and was subjected for radioiodine therapy at referral centre.
