Digital forensics 2.0: an automated, efficient, and privacy preserving digital forensic investigation framework

The current state of digital forensic investigation is continuously challenged by the rapid technological changes, the increase in the use of digital devices (both the heterogeneity and the count), and the sheer volume of data that these devices could contain. Although data privacy protection is not a performance measure, however, preventing privacy violations during the Digital Forensic Investigation, is also a big challenge. The investigator gets full access to the forensic image including suspect’s private data which may be sensitive at times as well as entirely unrelated to the given case under investigation. With a perception that privacy preservation and the completeness of investigation are incompatible with each other, the digital forensics researchers have provided solutions to address the above-stated challenges that either focus on the effectiveness of the investigation process or the data privacy preservation. However, a comprehensive approach that preserves data privacy by neither affecting the capabilities of the investigator nor the overall efficiency of the investigation process, is still an open problem. In the current work, the authors have proposed a digital forensic framework that uses case information, case profile data and expert knowledge for automation of the digital forensic analysis process; utilizes machine learning for finding most relevant pieces of evidence; and preserves data privacy in such a way that the overall efficiency of the digital forensic investigation process increases without affecting the integrity and admissibility of the evidence. The framework improves validation to enhance transparency in the investigation process. The framework also uses a secure logging mechanism to capture investigation steps to achieve a higher level of accountability. Since the proposed framework introduces notable enhancements to the current investigative practices more like the next version of Digital Forensics, the authors named it ‘Digital Forensics 2.0’, or DF 2.0 in short.
Impact of Physical Form of Linseed on Digestibility, Rumen Fermentation and Milk Yield of Dairy Cow

This work aimed to investigate the effect of supplementing different forms of linseed (meal , whole linseed and oil) to lactating cow's ration on milk yield and milk composition . Sixteen multifarious Friesian cows 15±2.26kg milk /d, and averaging 460±15.26 kg/body weight, were divided into four experimental feeding groups (4 each) for 180 days. All group animals were received concentrate feed mixture containing zero, linseed meal, whole linseed and oil linseed in ration A, B, C and D, respectively. All experimental rations were almost equals in energy and protein. Results indicated that supplementation of linseed meal recorded the highest FCM (13.60 kg/h./d.). There were no significant differences in milk composition among groups. Supplementation linseed oil (D) reduced the apparent digestibility of CF compared with control. The different form of oil seed did not influence ruminal pH but it caused significant (P<0.05) increased in ruminal ammonia concentrations for (C) and (D) groups compared with control. While, the concentration of volatile fatty acids was significantly (P<0.05) differ for cows fed (B) and (D) except those fed rations (C) compared with control . From the previous results, it could be concluded that using linseeds, especially meal, in lactating cow’s rations increased milk yield decreased feed cost and give more profit per Kg milk without adverse effects on cow’s health or performance.
Deep Eutectic Solvent-based Vortex-assisted Dispersive Liquid–liquid Microextraction Combined with High Performance Liquid Chromatography for the Determination of Phenolic Acids in Vegetable Oils

Vortex-assisted dispersive liquid–liquid microextraction (VA-DLLME) coupled with a high performance liquid chromatography–diode array detector (HPLC-DAD) was applied for the determination of phenolic acids (gallic, ferulic, and syringic) in vegetable oils. A deep eutectic solvent (DES) – a green extraction solvent – was synthesized by stirring choline chloride and urea at 80 ℃ until clarification. The experimental parameters affecting extraction efficiency, such as volume of extraction solvent, ionic strength, and extraction time were all optimized. Under optimal conditions, good linearities with the phenolic acids were achieved in the range 0.1 to 10 μg g –1 . The limits of detection varied between 0.010 and 0.021 μg g –1 , and the limits of quantification between 0.035 and 0.071 μg g –1 . The proposed DES-VA-DLLME-HPLC-DAD method is simple, time-saving, eco-friendly, and can be successfully applied to the extraction of phenolic acids from soybean, peanut, and blending vegetable oils with recoveries ranging from 75.6 % to 103.4 %.
Function Of Piwi-Interacting Rnas In Prostate Cancer

Background: As the most common cancer in male, prostate cancer makes up 9.5% of new cancer cases and 4.8% of all cancer death in US in 2018. Though the 5-year survival of prostate cancer is high and multiple treatments are available, the death rate of prostate cancer was still more than 19.5 per 100,000 men per year. With more and more evidence suggested that piRNA may play a more important role in tumorigenesis, we want to find out if piRNAs can be a potential treatment for prostate cancer. Method: Two Prostate cancer cell lines (PC3, LNCap) and a normal prostate cell line (WPMY-1) were either transfected with piR-021163 at treatment group or single-stranded random RNA sequence as negative control group. MTS, wound healing and colony formation assay were done after transfection to detect cancer cell proliferation, migration and anchorage-independent growth in vitro which are crucial for carcinogenesis. Total RNA from cells were also extracted for genome-wide expression profiling. The result of mRNA array was analyzed with IPA software to find gene expression level differences between piR021163 treated group and random RNA treated negative control group. Result: The result of in vitro test showed that ipR-021163 has different impact on different prostate cancer cell lines. In PC3 cells, it showed significant (p<0.001) decrease in cell proliferation (72h after transfection), migration (24h after transfection) and anchorageindependent growth (after 2 weeks of transfection) when transfected with piR-021163 protective allele comparing with negative control group. But no significant different was observed in the LNCap cell line. IPA analysis suggested that TNF might be a core functionally interrelated molecule in piR-021163 functional pathway. And transfection of piR-021163 may lead to the decrease of inflammation of body cavity. Conclusion: The role of piR-021163 in prostate cancer development and progression may be cancer subtype-specific. The cancer suppression effect of piR-021163 should be mediate through the activation TNF and is related with the inhibition of inflammation.
Morphological studies of cryopreserved Toda buffalo spermatozoa by CASA

Toda buffaloes are the endangered species of the Nilgiri Hills of South India. Successful attempts have been made in cryopreservation of semen of Toda bulls. Thawed semen samples from Toda buffalo bulls were used to analyze the spermatozoal morphometry by Computer assisted semen analyzer (CASA). Head length (major axis), width (minor axis), area, perimeter, elongation and tail length were the morphometrical characteristics measured. The mean (±SE) length, width, area, perimeter, elongation percentage and tail length were 7.38±0.02 µm, 4.68±0.02 µm, 28.53±0.17 µm2 , 20.32±0.19 µm, 62.95±0.22% and 52.93±0.41 µm respectively. Overall spermatozoal abnormality was 30.75% and coiled tail was the most common (50.49%) abnormality. The spermatozoal morphometry reported in this study may form a preliminary data in Toda buffalo semen analysis and helps for comparison with other breeds and can complement sperm motility assessment.
Oxidative modification of vesicular transporters in an animal model of Alzheimer’s disease

Oxidative stress is one of the major characteristics in Alzheimer’s disease, and converging evidence indicates that cysteine S-nitrosylation might be related in AD pathology. My results demonstrated exogenous S-nitrosoglutathione was able to S-nitrosylate vAChT, vMAT2, vGluT1 and vGluT2. S-nitrosylation of these vesicular transporters inhibited the uptake of [H]acetylcholine, [H]dopamine and [H]glutamate
EFFECT OF NATURAL ANTIOXIDANTS OF ORANGE PEEL ON SUNFLOWER OIL DURING STORAGE

Extracts of orange peel (Balady Var.) with different organic solvents (methanol, petroleum ether, ethanol diethylether, hexan and acetone) were studied. Methonol proved the best solvent for yeild extract. Antioxidant activity of sunflower oil treated with different concentrations of methanolic extracts of orange peel (MEOP) were also studied by determining peroxide value (POV), free fatty acid (FFA) and iodine value (IV) during 5 months storage at room temperature (20 + 3 O C). , Result indicated that: Orange peel is considered as a good source of polyphenols. Methanol proved the best solvents of yield extracts and also polyphenol contents. The higher concentration of MEOP, the Lower value of (POV) and FFA) and the higher value of IV was observed during storage at the end of storage. Sunflower oil treated with 1500 and 2000 ppm of MEOP showed a significant (p≤ 0.05) lower value of POVs (6.90 and 6.77 meq/ kg -1 ); FFA (0.280%, 0.275%) and higher IVs (67.0 and 70.3). Meanwhile, refined oil (POVs 77.3 meq/ kg -1 , FFA 0.710 and 1V, 51.2), respectively. Addition of BHT and BHT with 200 ppm showed POVs(10.4 and 8.80 meq/ kg -1 ); FFA (0.251 and 0.270) and IVs(71.3 and 71.0), respectively. MEOP proved their strong efficiency as a natural antioxidant activity as compared to BHT and BHA, therefore it is suggested that it can safety be used instead of synthetic antioxidants for preservation of oils and fats from peroxidation and rancidity.
Adv antages of power system state estimation using Phasor Measurement Units

An important tool for Energy Management Systems (EMS) is state estimation. Based on measurements taken throughout the network, state estimation gives an es- timation of the state variables of the power system while checking that these estimates are consistent with the mea- surements. Traditionally, input measurements have been provided by the SCADA system (Supervisory Control and Data Acquisition). A disadvantage is that the measurements are not synchronised, which means that state estimation is not very precise during dynamic phenomena in the network. With the advent of real-time Phasor Measurement Units (PMU's), synchronised phasor measurements are possible which allows monitoring of dynamic phenomena. In this pa- per, the effect of the asynchronicity of measurements on the accuracy of the state estimation is analysed. Also, the pos- sibility of using PMUs for state estimation and the effect of using PMU measurements as well as SCADA measurements is explored.
A picture is worth a thousand words: on visual aspects of user interfaces of radio-telescopes

In the context of developing the user interfaces (UIs) for the control room of SKA (Square Kilometer Array) we analysed the UIs of existing radio-telescopes from the perspective of the human visual perception processes, in order to identify ways to make important information more efficiently communicated to operators and astronomers on duty. It is known that visual information can be processed much faster than text and that images are more effective for remembering information. Our study shows that operators and astronomers have to rely predominantly on text-based UIs. For example, only colour changes and audible signals are used to attract users attention, while motion, animation or change in shape are usually neglected. Likewise, preattentive features are seldom used to focus user’s attention on important information. When running the telescope operators are likely to be concentrated on specific tasks and could fail to notice changes in the UI unless these changes are made as easy to find as possible. In this paper we identify parts of the UIs that could benefit by a wider exploitation of visual information; they include the health monitor, the weather monitor and the scheduler, and give some initial suggestions of possible solutions.
Position control and performance analysis of hydraulic system using two pump-controlling strategies

The role of hydraulic systems is quite evident especially in the case of heavy machineries employed in industries, where the utilisation of high forces amid large stiffness is the prerequisite. Nevertheless, there has been substantial effort put forward in the development of advanced control strategies which finally addressed the issue of the position control. Proportional–integral–derivative control strategy happens to be one among them, which is a versatile and widely renowned approach involved in the position control in this study. Although, it is quite frequently observed that the hydraulic actuation system possesses strong nonlinearities. In this article, two different actuator position control strategies, that is, swash plate control of main pump and speed control strategy of prime mover are compared. In swash plate control strategy, the proportional–integral–derivative controller adjusts the swash plate of main pump through servo mechanism, whereas in the speed control strategy, the proportional–integral–derivative controller adjusts the speed of the electric motor through variable-frequency drive. For this purpose, two MATLAB-Simulink models are developed and validated experimentally. It is found that swash plate control strategy has better dynamic and control performance than the speed control strategy catering same position demand of the linear actuator.

Horizontal gene transfer to a defensive symbiont with a reduced genome amongst a multipartite beetle microbiome

The loss of functions required for independent life when living within a host gives rise to reduced genomes in obligate bacterial symbionts. Although this phenomenon can be explained by existing evolutionary models, its initiation is not well understood. Here, we describe the microbiome associated with eggs of the beetle Lagria villosa, containing multiple bacterial symbionts related to Burkholderia gladioli including a reduced-genome symbiont thought to produce the defensive compound lagriamide. We find that the putative lagriamide producer is the only symbiont undergoing genome reduction, and that it has already lost most primary metabolism and DNA repair pathways. The horizontal acquisition of the lagriamide biosynthetic gene cluster likely preceded genome reduction, and unexpectedly we found that the symbiont accepted additional genes horizontally during genome reduction, even though it lacks the capacity for homologous recombination. These horizontal gene transfers suggest that absolute genetic isolation is not a requirement for genome reduction.
Representational Ecosystems in Architectural Design Studio Critiques - Do changes in the representational ecosystem affect tutors and students behaviors during design critiques?

Design studio critiques are key moments for students' learning and designing processes. During critiques, the representational ecosystem provides a setting for the critique to unfold. Tutors and students, while presenting and discussing students' designs, interact with each other and the representational ecosystem. In this article, a case study illustrates our method to measure the effect of a change of representational ecosystem on the critiques' activity. Our three settings include traditional desk critiques, 1/50 scale mockup critiques and immersive Virtual Reality critiques (with HYVE-3D). Each type of critique is analyzed by using video coding as well as protocol analysis.
Novel acaricides by nanotechnology against cattle ticks and their effect on physiological and productive performance

A field trail was conducted to evaluate the efficacy of capsules suspension formulation (CS) by nanotechnology and conventional acaricides against the cattle ticks (Hyalomma marginatum) and its effects on the body weight and blood parameters of Aberdeen angus cattle. Acaricides residues were determined in an animal's blood and milk. Thirty infested cattle were randomly divided into five groups, each one contains (3 bulls and 3 cows) based on the mean tick count. Results showed that, permethrin 25 % CS and lambada-cyhalothrin 10 % CS were significantly the most effective against ticks (2.7 and 3.8 ticks/animal, respectively) compared to fipronil 20 % SC and Acetamiprid 20 % SL (8.3 and 6.3 ticks/animal, respectively) after 70 days of treatment. Permethrin 25 % CS achieved 100 % control against highly ticks' infestation after 3 days of treatment and maintained for 56 days without its residues in blood and milk samples. Conversely, fipronil residue was detected in the cow's blood and milk (1.3 and 2.7 µg/l, respectively) however, it's non detected in bull's blood after 1 week of treatment. They gradually decreased to below detection limits after 3 and 6 weeks respectively. The animal body weight was significantly increased, additionally: the liver and kidney function were decreased to normal level in all treated animals. Finally, permethrin and lambda-cyhalothrin that formulated CS can be used as efficient acaricides and a safe alternative in tick control strategy in tropical areas.
MFCSNet: Multi-Scale Deep Features Fusion and Cost-Sensitive Loss Function Based Segmentation Network for Remote Sensing Images

Semantic segmentation of remote sensing images is an important technique for spatial analysis and geocomputation. It has important applications in the fields of military reconnaissance, urban planning, resource utilization and environmental monitoring. In order to accurately perform semantic segmentation of remote sensing images, we proposed a novel multi-scale deep features fusion and cost-sensitive loss function based segmentation network, named MFCSNet. To acquire the information of different levels in remote sensing images, we design a multi-scale feature encoding and decoding structure, which can fuse the low-level and high-level semantic information. Then a max-pooling indices up-sampling structure is designed to improve the recognition rate of the object edge and location information in the remote sensing image. In addition, the cost-sensitive loss function is designed to improve the classification accuracy of objects with fewer samples. The penalty coefficient of misclassification is designed to improve the robustness of the network model, and the batch normalization layer is also added to make the network converge faster. The experimental results show that the classification performance of MFCSNet outperforms U-Net and SegNet in classification accuracy, object details and prediction consistency.

Synthesis, characterization and rheological properties of acrylamide/ acidic monomer/ N-(4-ethylphenyl) acrylamide Terpolymers as pH- responsive hydrogels and nanogels

ABSTRACT Novel pH-responsive superabsorbent hydrogels (HGs) and nanogels (NGs) with high water uptake and adjustable viscoelastic behavior were synthesized by free radical polymerization of acrylamide (AM) and a small amount of N-(4-ethylphenyl)acrylamide (EΦAM) hydrophobic comonomer in the presence of three different acidic monomers. Structure of the synthesized linear terpolymers was investigated by 1H-NMR spectroscopy. The solution viscosity of the linear terpolymers was measured at different pH and temperatures, where AM-EΦAM-AMPS terpolymer showed higher viscosity in different conditions. Equilibrium swelling ratio (ESR) of hydrogels was studied using response surface methodology and empirically modeled as a function of pH and temperature as stimuli. Graphical Abstarct
Association study of an SNP in TLR1 gene with susceptibility to bovine tuberculosis in cows

Toll like Receptor 1 (TLR1) gene codes for a host pathogen recognition receptor that plays a vital role in the pathogen recognition and initation of immune response and is a suitable candidate gene for identifying genetic predisposition to infectious diseases like Bovine Tuberculosis (bTB). In the present study, an attempt was made to investigate the genetic polymorphism at SNP locus rs55617193 in TLR1 gene and explore association of genetic variants at this locus with susceptibility to bTB infection in cattle. In a population of bTB affected and healthy cows established using single intradermal tuberculin test; SNP under investigation was found to be polymorphic. SNP locus 55617193 in TLR1 gene was however found to be nonsignificantly associated with susceptibility to bTB in the study population. These findings need added validation in independent, large case-control population of bTB along with association studies of other SNPs in TLR genes.
