Data Exfiltration Techniques and Data Loss Prevention System (2019)

One of the primary concerns of data security specialists is to mitigate insider threats and prevent data leaks. Often, unfortunately, insider threats go unnoticed. In most cases, the longer such activity goes unnoticed, the greater the resulting damages are likely to be. This paper provides an overview of the basic data exfiltration techniques that deal with file structures and were utilized in multiple scenarios in an attempt to bypass a Data Loss Prevention system. Details show which of the scenarios have been detected and which have not been by the Data Loss Prevention system. The paper also proposed solutions for the undetected scenarios.
Crystal Structure of Carbon Dioxide at High Pressure: “Superhard” Polymeric Carbon Dioxide (1999)

The crystal structures of two molecular phases (I and III) and a polymeric phase (V) of ${\mathrm{CO}}_{2}$ have been investigated to 60 GPa. ${\mathrm{CO}}_{2}\ensuremath{-}\mathrm{I}$ $(\mathrm{Pa}3)$ transforms to ${\mathrm{CO}}_{2}\ensuremath{-}\mathrm{III}$ $(\mathrm{Cmca})$ at 12 GPa with almost no change of density. Although ${\mathrm{CO}}_{2}\ensuremath{-}\mathrm{III}$ persists in $\mathrm{Cmca}$ to at least 60 GPa at ambient temperature, it transforms when heated to 1800 K above 40 GPa to tridymite $({P2}_{1}{2}_{1}{2}_{1})$ ${\mathrm{CO}}_{2}\ensuremath{-}\mathrm{V}$ with $15.3%$ volume change. Each carbon atom of ${\mathrm{CO}}_{2}\ensuremath{-}\mathrm{V}$ is tetrahedrally bonded to four oxygen atoms. ${\mathrm{CO}}_{2}\ensuremath{-}\mathrm{V}$ is likely superhard with low compressibility ${B}_{0}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}365\phantom{\rule{0ex}{0ex}}\mathrm{GPa}$, similar to cubic BN.
An Automated Blur Detection Method for Histological Whole Slide Imaging (2013)

Whole slide scanners are novel devices that enable high-resolution imaging of an entire histological slide. Furthermore, the imaging is achieved in only a few minutes, which enables image rendering of large-scale studies involving multiple immunohistochemistry biomarkers. Although whole slide imaging has improved considerably, locally poor focusing causes blurred regions of the image. These artifacts may strongly affect the quality of subsequent analyses, making a slide review process mandatory. This tedious and time-consuming task requires the scanner operator to carefully assess the virtual slide and to manually select new focus points. We propose a statistical learning method that provides early image quality feedback and automatically identifies regions of the image that require additional focus points.

DNA analysis reveals genetic homogeneity and single nucleotide polymorphism in 5.8S ribosomal RNA gene spacer region among commercial cultivars of the button mushroom Agaricus bisporus in India (2007)

Molecular variation was studied among 22 white pileus cultivars of Agaricus bisporus using random amplified polymorphic DNA markers and by sequence analysis of 5.8S rRNA gene along with ITS regions. Twenty-four primers amplified 175 RAPD markers, of which 53.7% were polymorphic. Genetic similarity index varied from 0.64 to 0.99, with an average of 0.81. The varieties exhibited 92.7% genetic similarity, while the hybrids showed 84.3% similarity amongst them. Both the UPGMA dendrogram and PCO plot grouped all the varieties into a single cluster, while the hybrids formed a separate cluster exhibiting DNA polymorphism. The length of ITS1, 5.8S rRNA gene and ITS2 was 290, 154 and 208 bases respectively, in all the genotypes of A. bisporus studied. We report two single nucleotide polymorphisms (SNPs) at 522 and 563 nucleotide positions in the ITS2 region which distinguished different strains within the species. This study demonstrates that the RAPD markers are useful and robust tools for identification of hybrids in the germ plasm and for detection of intraspecific molecular variation in the white button mushroom cultivars. In the present study we report the identification of SNPs in the ITS2 region of the 5.8S ribosomal RNA gene which could differentiate cultivars of A. bisporus.

Identity Management in the Internet of Things: the Role of MANETs for Healthcare Applications (2013)

The Internet of Things (IoT) in healthcare and medical applications promises to solve many problems which are currently challenging the sector, ranging from remotely caring for our aging population to medical discoveries on incurable diseases. However, the challenges and risks of having 50 billion Things and users connected together are complex and may be detrimental to control. Concerns have been raised in relation to the IoT Identification Management (IDM) issues, in which each Thing (user and device) will be required to have a unique identity, and the IDM to be able to distinguish between a device and user, as well as ensuring identity and information context safety. This paper examines the underlying issues behind IDM and proposes a framework which aims to achieve the identification of Things and their safe management. The IDM framework is embedded in Mobile Ad Hoc Networks (MANETs) and assumes that most healthcare devices will be linked wirelessly and in mobile environments. The paper aims to open a research debate which will help to solve the future IoT IDM issues in healthcare applications.
Relationships between serum prolactin levels and follicle stimulating hormone response to luteinizing hormone-releasing hormone during early puerperium (1983)

The effect of serum prolactin (Prl) levels on pituitary response to iv luteinizing hormone-releasing hormone (LRH) (100 micrograms) was studied in 23 normal puerperal women on day 1 post-partum. All women had an uneventful full-term pregnancy and delivery. The LRH test was repeated in 8 of the women on day 3 and in the remaining 15 on day 6 post-partum. Serum Prl levels were high on days 1 and 3, but decreased significantly on day 6 (P less than 0.01). No pituitary FSH response to LRH stimulus was found on day 1 post-partum in all 23 women. In those who were given placebo, FSH levels in serum did not change in response to LRH on day 3 (4 women), but increased significantly on day 6 (5 women) in all subjects (P less than 0.05). Conversely, when oral metoclopramide was given from day 1 to 6 (10 women) the responsiveness of FSH to LRH on day 6, found in the placebo group, was not observed. Early reduction of serum Prl values on day 3 post-partum by bromocriptine treatment from day 1 to 3 (4 women) did not accelerate the FSH response to LRH. These results suggest an inhibitory effect of elevated serum Prl on the pituitary FSH response to LRH in women during early puerperium.

Míneria y poblamiento en Antioquia, siglos XVII y XVIII (Borrador de administración No. 6) (2008)

La explotacion aurifera, como eje central de la economia antioquena, estaba representada en dos sentidos. En primer lugar, el oro se constituyo en el motor de la actividad economica de la provincia y, en segundo lugar, el oro funciono como moneda para el intercambio y como capital disponible para realizar nuevas inversiones. De esta manera, el metal fungia como mercancia y como medio de pago, y se constituia como articulador de la provincia al comercio imperial espanol; por tal razon, el estudio de los ciclos de produccion aurifera se ha convertido en el eje central de la mayor parte de los estudios sobre el periodo colonial antioqueno (Suarez Pinzon 1993, 27).
Frequent abnormalities of the putative tumor suppressor gene FHIT at 3p14.2 in pancreatic carcinoma cell lines. (1998)

The FHIT gene is localized on chromosome 3p14, a region including a tumor cell-specific, commonly deleted region. To determine the role of the FHIT gene in pancreatic carcinogenesis, 14 pancreatic carcinoma cell lines were analyzed by reverse transcription-PCR and exon-specific PCR amplification of genomic DNA. The full-length FHIT transcript was lost in 70% of the pancreatic carcinoma cell lines analyzed, while 66% also revealed intragenic homozygous deletions of exons 3, 4, and 5. Truncated FHIT transcripts lacking a variable number of exons most likely represented alternative splicing products. Fhit protein expression was dependent on a full-length FHIT transcript. The results suggest that the FHIT gene may be a target tumor suppressor gene involved in pancreatic carcinogenesis.
High-performance automatic cropping and deskew of multiple objects on scanned images (2014)

The paper is devoted to a novel high-performance algorithm for automatic segmentation and skew correction of several objects on a scanned image. The complex multi-stage technique includes preprocessing, initial segmentation, classification of connected regions, merging of fragmented regions by heuristic procedure, bounding boxes detection and deskew of rectangular objects. Our method is highly effective owing to unification most of operations in one pass. Algorithm provides users with additional functionality and comfort. The method is evaluated by suggested quantitative quality criteria.

Modeling GPS phase multipath with SNR: Case study from the Salar de Uyuni, Boliva (2008)

Multipath, wherein a signal arrives at the receiving antenna by more than one path, is a significant and largely unmodeled source of GPS positioning error. We present a technique for mitigating specular multipath in GPS carrier phase measurements using the signal‐to‐noise ratio (SNR), in which the frequency and amplitude content of non‐stationary oscillations in SNR are modeled to extract multipath parameters (direct and reflected signal amplitudes, and the phase difference between direct and indirect signals). The frequency content of SNR data is estimated using wavelet analysis, then used to initialize an adaptive least squares process to solve for time‐varying multipath parameters. Multipath corrections derived from these parameters are applied to the phase observables. We demonstrate this technique using campaign GPS data collected over a large salt flat (Salar de Uyuni), specifically a tripod‐mounted station which experienced long‐period (300–2000 s) multipath oscillations in SNR from ground reflections. By contrasting position solutions before and after applying multipath corrections, we demonstrate a reduction in carrier phase postfit residual RMS of up to 20% for static positioning, and 1–7 dB reduction in spectral power at multipath periods for kinematic positions.

Diadenosine tetraphosphate (Ap4A) – an E. coli alarmone or a damage metabolite? (2017)

Under stress, metabolism is changing: specific up- or down-regulation of proteins and metabolites occurs as well as side effects. Distinguishing specific stress-signaling metabolites (alarmones) from side products (damage metabolites) is not trivial. One example is diadenosine tetraphosphate (Ap4A) - a side product of aminoacyl-tRNA synthetases found in all domains of life. The earliest observations suggested that Ap4A serves as an alarmone for heat stress in Escherichia coli. However, despite 50 years of research, the signaling mechanisms associated with Ap4A remain unknown. We defined a set of criteria for distinguishing alarmones from damage metabolites to systematically classify Ap4A. In a nutshell, no indications for a signaling cascade that is triggered by Ap4A were found; rather, we found that Ap4A is efficiently removed in a constitutive, nonregulated manner. Several fold perturbations in Ap4A concentrations have no effect, yet accumulation at very high levels is toxic due to disturbance of zinc homeostasis, and also because Ap4A's structural overlap with ATP can result in spurious binding and inactivation of ATP-binding proteins. Overall, Ap4A met all criteria for a damage metabolite. While we do not exclude any role in signaling, our results indicate that the damage metabolite option should be considered as the null hypothesis when examining Ap4A and other metabolites whose levels change upon stress.
Weakly Supervised Video Object Segmentation (2018)

This paper proposes a novel approach of weakly supervised video object segmentation, which only needs one pixel to guide the segmentation. We use two deep neural networks to get the instance-level semantic segmentation masks and optical flow maps of each frame. An object probability map to the first frame in video is generated by combining the semantic masks, the optical flow maps and the guiding pixel. The object probability map propagates forward and backward and becomes more accurate to each frame. Finally, an energy minimization problem on a function that consists of unary term of object probability and pairwise terms of label smoothness potentials is solved to get the pixel-wise object segmentation mask of each frame. We evaluate our method on a benchmark dataset, and the experimental results show that the proposed approach achieves impressive performance in comparison with state-of-the-art methods.
Sequence similarity of human caliciviruses and small round structured viruses (1994)

The application of reverse transcription-polymerase chain reaction (RT-PCR) using primers directed to the RNA dependent RNA polymerase region within ORF1 of Norwalk virus (NV) showed that 31 percent of morphologically typical human caliciviruses (HuCV) and 57% of small round structured viruses (SRSVs) produced a product of 470 bp similar to the NV control, NV 8FIIa/68/US. Alignment of the amino acid sequences of morphologically typical HuCVs with previously published sequences for SRSVs, NV, and Snow Mountain agent (SMA) showed a high degree of homology (90-92%) with SMA and a lesser extent of homology with NV (60-61%). The amino acid sequence of two strains of HuCV, HuCV/3C/92/UK, and HuCV/5C/92/UK differed by only one or two amino acids respectively in the RNA dependent RNA polymerase region from that of two strains of SRSV obtained from children in the United Kingdom, SRSV/4S/90/UK and Japan, SRSV/OTH-25/89/J which were found to have identical amino acid sequences. The use of an EIA for detection of NV antigen employing antisera raised to recombinant NV protein indicated that HuCVs and SRSVs obtained from children and adults in the United Kingdom were antigenically distinct from the prototype Norwalk virus, NV/8fIIa/68/US.
CARIES PATTERNS IN PRIMARY DENTITION BY CARIES EXPERIENCE OF INDIVIDUAL TEETH (1999)

To study the caries patterns in primary dentition, 719 preschool children, 4-6 years old, were examined for their caries activity(salivary reductase activity) and caries experience of individual teeth. Teeth groups were made by cluster analysis using dft indexes of individual teeth as criteria. The six major teeth groups in the order of dft index from high to low were (1) lower primary molars, (2) upper primary molars, (3) upper central incisor, (4) upper lateral incisor, (5) canines, and (6) lower incisors. There were significant differences in dft index between teeth groups except upper lateral incisor and canines. Upper and lower primary molars showed the highest correlation in dft index, and the next couples were upper central incisors and upper lateral incisors, upper lateral incisor and canines, upper central incisor and canines, upper lateral incisor and upper primary molars, and canines and upper primary molars in descending order. Upper first primary molar showed the greatest differences in dft index between caries activity levels.
A Novel Extracellular Diterpenoid with Antibacterial Activity from the Cyanobacterium Nostoc commune (1999)

A novel extracellular metabolite with an unprecedented diterpenoid skeleton, 8-[(5-carboxy-2-hydroxy)benzyl]-2-hydroxy-1,1,4a,7, 8-pentamethyl-1,2,3,4,4a,6,7,8,8a,9,10,10a-dodecahydrophenanthrene , has been isolated from the culture medium of the terrestrial cyanobacterium Nostoc commune Vaucher (EAWAG 122b) by means of bioguided isolation. The molecule was designated as noscomin. The structure was determined by spectroscopic methods, mainly NMR and mass spectrometry. Noscomin exhibited antibacterial activity against Bacillus cereus, Staphylococcus epidermidis, and Escherichia coli.
Precision mapping of snail habitat provides a powerful indicator of human schistosomiasis transmission (2019)

Recently, the World Health Organization recognized that efforts to interrupt schistosomiasis transmission through mass drug administration have been ineffective in some regions; one of their new recommended strategies for global schistosomiasis control emphasizes targeting the freshwater snails that transmit schistosome parasites. We sought to identify robust indicators that would enable precision targeting of these snails. At the site of the world's largest recorded schistosomiasis epidemic-the Lower Senegal River Basin in Senegal-intensive sampling revealed positive relationships between intermediate host snails (abundance, density, and prevalence) and human urogenital schistosomiasis reinfection (prevalence and intensity in schoolchildren after drug administration). However, we also found that snail distributions were so patchy in space and time that obtaining useful data required effort that exceeds what is feasible in standard monitoring and control campaigns. Instead, we identified several environmental proxies that were more effective than snail variables for predicting human infection: the area covered by suitable snail habitat (i.e., floating, nonemergent vegetation), the percent cover by suitable snail habitat, and size of the water contact area. Unlike snail surveys, which require hundreds of person-hours per site to conduct, habitat coverage and site area can be quickly estimated with drone or satellite imagery. This, in turn, makes possible large-scale, high-resolution estimation of human urogenital schistosomiasis risk to support targeting of both mass drug administration and snail control efforts.
Advancements in MIMO antenna systems (2018)

Multiple-input-multiple-output (MIMO) technology is currently used in fourthgeneration (4G) wireless systems because they can provide higher data rates at fixed power and bandwidth levels when compared to their single-input-singleoutput conventional counterparts. MIMO-enabled systems require the integration of multiple antenna elements operating at the same band to provide higher data throughput. The design of such antenna solutions is a challenging task especially for small form factor devices where the space is limited and the antennas are placed close to one another. Such close placement of antennas with respect to one another will increase the port coupling between adjacent antennas as well as radiated field coupling, thus degrading the efficiency as well as increasing field correlation. This will affect the overall improvement in the data rates (channel capacity) expected. In this chapter, we will go over the latest advancements in MIMO antenna system designs for 4G and the anticipated 5G wireless standard and will highlight various challenges that can be encountered and provide the solutions to overcome them.
