Actions and fermionic symmetries for D-branes in bosonic backgrounds

In this article we derive the full interacting effective actions for supersymmetric D-branes in arbitrary bosonic type II supergravity backgrounds. The actions are presented in terms of component fields up to second order in fermions. As one expects, the actions are built from the supercovariant derivative operator and the $\kappa$-symmetry projector. The results take a compact and elegant form exhibiting $\kappa$-symmetry, as well as supersymmetry in a background with Killing spinors. We give the explicit transformation rules for these symmetries in all cases, including the M2-brane. As an example, we analyze the N=2 super-worldvolume field theory defined by a test D4-brane in the supergravity background produced by a large number of D0-branes. This example displays rigid supersymmetry in a curved spacetime.
Voltage‐Tension Relations in Single Frog Atrial Cardiac Cells

Voltage-clamp experiments were performed on isolated single frog (Rana catesbeiana or Rana pipiens) atrial cells to determine the voltage-contraction relations of the single cardiac cell. The contractile responses of the single cell associated with long duration (3 second) depolarizing steps consisted of a rise to peak (phasic) followed by a decay to a sustained contraction (tonic). These phasic-tonic type contractile responses could be obtained under conditions where membrane potential was well controlled along the entire length of the cell. Thus, the data obtained on the single cell indicate that the phasic-tonic contractile response is the characteristic contractile response of frog atrial tissue. The voltage dependence of the extent of relaxation to the tonic component following the peak of the contraction was affected dramatically by the intracellular sodium concentration. This result indicates that both the relaxation following peak contraction as well as the tonic contraction are related to calcium control via the sodium-calcium exchanger. The data also indicate that calcium entry via the inward calcium current is required for the contractile response to have a phasic component. These data indicate that calcium entry via the inward calcium current followed by the sodium-calcium exchanger first reducing and then maintaining the intracellular calcium level produces the characteristic phasic-tonic contractile response.
Online RRT∗ and online FMT∗: Rapid replanning with dynamic cost

Traditional path-planning involves (1) choosing start and goal points, (2) calculating a path, and (3) following that path. There are, however, many real world scenarios where an agent might need to change its goal and replan, which frequently includes expensively calculating a new path from scratch. We propose an adaptation to RRT∗ that locally rewires the RRT∗ tree as the robot moves and path costs change. Local rewiring takes advantage of information already existing in the tree and makes small adaptations that accommodate changes. Rewiring adds computational overhead during robot travel, but allows replanning in real time with approximately constant overhead. Empirical studies demonstrate that computational costs are lower than alternative replanners in 2D worlds with moderate obstacle density, and the resulting paths approach optimality as more time is allowed to replan.
The Robot Intelligence Kernel

The Robot Intelligence Kernel (RIK) is a portable, reconfigurable suite of perceptual, behavioral, and cognitive capabilities that can be used across many different platforms, environments, and tasks. The RIK coupled with a virtual 3D interface have been shown to dramatically improve human-robot interactions across a variety of navigation and exploration tasks.
SYNAPTOSOMAL PLASMA MEMBRANES. ACYL GROUP COMPOSITION OF PHOSPHOGLYCERIDES and (Na++ K+)‐ATPase ACTIVITY DURING FATTY ACID DEFICIENCY

Abstract— Essential fatty acid deficiency was induced in mice after feeding a fatty acid deficient diet for 6 months. Activity of the (Na++ K+)‐ATPase in the total brain homogenates and in isolated synaptosomal plasma membranes was significantly higher (P & lt; 0 05) in the deficient mice than the controls. Analysis of the acyl group composition of phosphoglycerides in brain as well as in the synaptosomal plasma membranes showed that mice fed the deficient diet had increased levels of 20:3(n‐9) and 22:3(n‐9) and decreased levels of 20:4(n‐6) and 22:4(n‐6). However, acyl group changes varied among individual phosphoglycerides and were most obvious in the two species of ethanolamine phosphoglycerides. A decrease in 22:6(n‐3) level was also observed in some phosphoglycerides of the synaptosomal plasma membranes especially the diacyl‐sn‐glycerophosphorylserine. In this experiment, a new solvent system for chromatographic separation of the diacyl‐sn‐glycerophosphorylserine and diacyl‐sn‐glycerophosphorylinositol was reported. The separation technique was suitable for analysis of acyl group composition of individual phosphoglycerides by gas‐liquid chromatography. The results were consislent with a positive correlation of the non‐polar acyl groups of brain membranes with the active ion transport activity. The increase in enzymic activity during deficient state may be the result of a biological adaptation due to structural alteration of the brain membranes.
Optimal Channel Sensing for Heterogeneous Cognitive Networks: An Analytical Approach

The problem of optimal channel sensing in heterogeneous cognitive networks is considered to maximize the system throughput performance. The characteristics of an optimal operating sensing point maximizing the overall system rate are investigated under several rate criteria including the sum rate, the minimum of the primary and secondary rates, and the secondary rate with a guaranteed primary rate. Under the sum rate criterion, it is shown that the loss by imperfect sensing is no greater than half of the sum rate achieved by the perfect time sharing approach in a two user case if the sensing point is optimally designed.
Clinical response to aminoglycoside therapy: importance of the ratio of peak concentration to minimal inhibitory concentration.

In an examination of the relationships among plasma aminoglycoside concentrations, the minimal inhibitory concentration (MIC) for the infecting organism, and therapeutic outcome, data were analyzed from 236 patients with gram-negative bacterial infections who were participants in four clinical trials of gentamicin, tobramycin, and amikacin. Clinical response to therapy occurred in 188 (80%) patients. Elevated maximal and mean peak aminoglycoside concentration/MIC ratios were strongly associated with clinical response (P less than .00001 and P less than .0001, respectively). A graded dose-response effect was found between an increasing maximal peak concentration/MIC ratio and clinical response. By logistic regression the peak concentration/MIC ratios were associated significantly with clinical response after adjustment for underlying severity of illness and other factors correlated with response. These results demonstrate that a high peak concentration relative to the MIC for the infecting organism is a major determinant of the clinical response to aminoglycoside therapy.
Testing for proportionality of multivariate dispersion structures using interdirections

Knowing whether the dispersion structures of two elliptically symmetric populations are proportional is an important problem in multivariate data analysis. Since the problem is invariant under nonsingular transformations it is possible to reduce it to the situation where one population is spherically symmetric while the other has a diagonal dispersion structure. In this article we develop a nonparametric test procedure based on the idea of inter directions, introduced by Randies (1989) in the context of multivariate sign tests. The findings of this article also enhance the possibility of developing a technology for robust multivariate data analysis using such fundamentally geometric concepts.
Periodontal plastic surgery of gingival recessions at single and multiple teeth

This manuscript aims to review periodontal plastic surgery for root coverage at single and multiple gingival recessions. Techniques are assessed based on biological principles, surgical procedures, prognosticative factors and expected clinical and esthetic outcomes. The use of coronally advanced flap, laterally sliding flap, free gingival graft, the tunnel grafting technique, barrier membranes, enamel matrix derivative, collagen matrix and acellular dermal matrix are evaluated. The clinical scenario and practical implications are analyzed according to a modern evidence-based approach.
Visible light positioning: a roadmap for international standardization

The widespread introduction of white LEDs for illumination provides a unique opportunity to create an indoor positioning system that is flexible, accurate, and ubiquitous. Signals transmitted by the LEDs are used to determine the position of a person or object within a room. To take full advantage of this new opportunity, it is essential that comprehensive and robust international standards are developed before a plethora of incompatible proprietary systems flood the market. In this article, we discuss the very diverse range of potential applications of these future systems and their implications for the design of a new standard. Another consideration is that the transmission of positioning signals must not compromise the primary function of the LEDs, which is energy-efficient illumination, so visible flicker must be avoided. Position information can be derived from a range of properties of the received signal, such as the power of the received signal or the angle at which the signal reaches the receiver. The suitability of different techniques for an indoor positioning system is considered. Finally, we discuss the implications each of these aspects has for the design of an effective standard.
Invited commentary: are low radiation doses or occupational exposures really risk factors for malignant melanoma?

Concerns about a possible association between melanoma and employment in the nuclear industry first surfaced in the early 1980s (1), and even earlier with regard to employment in other industries (2). Although occupationally related skin disorders were first observed in the 1700s (3), and although radiationinduced skin erythemas and skin cancers were observed among early radiation workers as well as among populations undergoing radiation therapy (4, 5), observations regarding the possible association between occupational exposures and melanoma have tended to receive little credence (6). In 1981, Austin et al. (1) reported results from a retrospective cohort study, including a fourfold increase in the incidence of melanoma, among workers at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California. These findings generated concern that other nuclear workers might be similarly subject to increased risk of melanoma, perhaps due to job-related exposures to low doses of ionizing radiation. Studies carried out at a sister laboratory, Los Alamos National Laboratory (LANL) (7, 8), indicated that increased melanoma incidence did not exist among LANL workers as a whole (7), and further that only increasing education level was clearly associated with the occurrence of incident melanoma within this cohort (8). The case-control study reported by Austin and Reynolds (9) in this issue of the Journal continues the analysis of melanoma among LLNL workers that was originally reported in 1981 (1). The current investigation expands the total number of melanoma cases from the 19 reported in the 1981 study to 31. The study window for case ascertainment is also increased from
Performance analysis of 3-D monolithic integrated circuits

3-D monolithic integration (3DMI), also termed as sequential integration, is a potential technology for future gigascale circuits. Since the device layers are processed in sequential order, the size of the vertical contacts is similar to traditional contacts unlike in the case of parallel 3-D integration with through silicon vias (FSVs). Given the advantage of such small contacts, 3DMI supports stacking active layers such that fine-grain integration of 3-D circuits can be implemented. This paper extends the idea of constructing the standard cells across two active layers, forming 3-D cells, to reduce the overall area and interconnect wirelength of a circuit. To demonstrate the effect of the 3DMI technology on these important parameters of circuit design, two important communication blocks are evaluated. Specifically, a low-density-parity-check (LDPC) decoder as a sample of interconnect-dominated circuit and a data-encryption-standard (DES) block, which is good instance of a gate dominated circuit, are investigated. By employing 3-D cells in the conventional design flow chain, there is more than 10% decrease in wirelength for both circuits (in wirelength driven placement mode). However, when subjected to timing driven placement a slight reduction in delay (1.6%) is observed for an LDPC decoder, whereas for the DES block considerable delay reduction (14.22%) is achieved.
Objects of the people, by the people, and for the people

Computers were invented largely as mental aids. In inventing object-orientation, Alan Kay renewed that vision on a metaphorical level that no longer subordinated computers to human minds. Trygve Reenskaug tried to link the worlds of the human and the computer together with Model-View-Controller, but at the time he got only half the job done. Today we're stuck in this Kantian object world where individual objects act alone and programmers live inside of classes looking out: there is rarely any sense of collective behaviour in object-oriented systems, and there is rarely any degree of behavioural (self-)organization. I have been working with Trygve on a paradigm called DCI (Data, Context and Interaction) that places the human experiences of design and use of programs equally at centre stage. It balances the object interaction view with the traditional data conceptualization of class-oriented programming. DCI offers a vision of computers and people being mutually alive in Christopher Alexander's sense of great design. It serves Kay's original vision of object-orientation powering computers as mental adjuncts, as well as his vision of objects as a recursion on the concept of a computer. In this world with a rapidly growing number of increasingly connected human minds, DCI opens up a playful dialogue contrasting metaphors of collective human reasoning and Kay's vision of object computation.
The role of visfatin in cancer proliferation, angiogenesis, metastasis, drug resistance and clinical prognosis

Abstract Visfatin, also known as nicotinamide phosphoribosyltransferase or pre-B-cell colony-enhancing factor (PBEF), is an adipocytokine secreted by adipocytes, macrophages and inflamed endothelial tissue. Related reports have indicated a positive correlation between the visfatin level and obesity and cancer risk. In addition to its original function, visfatin is multifunctional and plays critical roles in the promotion of several processes relevant to cancer progression including cancer cell proliferation, angiogenesis, metastasis and drug resistance. The relative expression of visfatin and the potential visfatin receptor on a pan-cancer scale was determined based on the transcriptome analysis data in The Cancer Genome Atlas. We further show the clinical association of its signaling axis with the survival of cancer patients, which reveals its prognostic power for specific cancer types. This review illustrates visfatin’s biological functions related to cancer progression and demonstrates its clinical significance in predicting outcomes of cancer patients.
Cognitive Media Attributes and Motivation of IPTV for Agricultural Information

New digital media forms have broaden new business opportunities. Internet Protocol Television (IPTV) has emerged as a major contender, from these new digital media options. Agricultural and food industries are especially excited and looking forward to employing IPTV as they see it as a viable means in promoting their markets. This study examines whether the effects of media attributes and motivations affect cognitive necessity and usefulness on viewers. 254 observations of survey were collected from members of an agriculture-related web-site which shows how media attributes can impact the cognitive necessity of viewers and how motivational factors of use can influence cognitive usefulness of those viewers. From these results, IPTV service providers can obtain insight on their future programs and the proper use of their application.

Searching on Trees with Noisy Memory

We consider a search problem on trees using unreliable guiding instructions. Specifically, an agent starts a search at the root of a tree aiming to find a treasure hidden at one of the nodes by an adversary. Each visited node holds information, called advice, regarding the most promising neighbor to continue the search. However, the memory holding this information may be unreliable. Modeling this scenario, we focus on a probabilistic setting. That is, the advice at a node is a pointer to one of its neighbors. With probability $q$ each node is faulty, independently of other nodes, in which case its advice points at an arbitrary neighbor, chosen u.a. r. Otherwise, the node is sound and necessarily points at the correct neighbor. Crucially, the advice is permanent, in the sense that querying a node several times would yield the same answer. We evaluate the agent's efficiency by two measures: The move complexity denotes the expected number of edge traversals, and the query complexity denotes the expected number of queries. Let $\Delta$ denote the maximal degree. Roughly speaking, the main message of this paper is that in order to obtain efficient search, $1/\sqrt{\Delta}$ is a threshold for the noise parameter $q$. Essentially, we prove that above the threshold, every search algorithm has query complexity (and move complexity) which is both exponential in the depth $d$ of the treasure and polynomial in the number of nodes $n$. Conversely, below the threshold, there exists an algorithm with move complexity $O(d\sqrt{\Delta})$, and an algorithm with query complexity $O(\sqrt{\Delta}\log \Delta \log^2 n)$. Moreover, for the case of regular trees, we obtain an algorithm with query complexity $O(\sqrt{\Delta}\log n\log\log n)$. The move complexity bound is tight below the threshold and the query complexity bounds are not far from the lower bound of $\Omega(\sqrt{\Delta}\log_\Delta n)$.
VIPOC Project Research Summary (Discussion Paper)

Predicting the output power of renewable energy production plants distributed on a wide territory is a valuable goal, both for marketing and energy management purposes. In this paper, we describe Vi-POC (Virtual Power Operating Center) – a distributed system for storing huge amounts of data, gathered from energy production plants and weather prediction services. Due to the heterogeneity and the high volume of data, it is necessary to exploit suitable Big Data analysis techniques in order to perform a quick and secure access to data that cannot be obtained with traditional approaches for data management. We use HBase over Hadoop framework on a cluster of commodity servers in order to provide a system that can be used as a basis for running machine learning algorithms. We perform one-day ahead forecast of PV energy production based on Artificial Neural Networks in two learning settings – structured and non-structured output prediction. Preliminary experimental results confirm the validity of the approach, also when compared with a baseline approach.
Biological Effects of a Carbohydrate-Binding Protein from an Annelid, Perinereis nuntia Against Human and Phytopathogenic Microorganisms

Lectins have a good scope in current clinical microbiology research. In the present study evaluated the antimicrobial activities of a D-galactose binding lectin (PnL) was purified from the annelid, Perinereis nuntia (polychaeta) by affinity chromatography. The molecular mass of the lectin was determined to be 32 kDa as a single polypeptide by SDS-PAGE under both reducing and non-reducing conditions. The hemagglutinating activity of the PnL showed against trypsinized and glutaraldehyde-fixed human erythrocytes was specifically inhibited by D-Gal, GalNAc, Galβ1-4Glc and Galα1-6Glc. PnL was evaluated for in vitro antibacterial screening studies against 11 gram-positive and gram-negative microorganisms. From the screening results, it was revealed that PnL exhibited significant antibacterial activity against gram-positive bacteria. Bacillus megaterium showed the highest growth inhibition by the lectin (250 μg/disc). However, PnL did not inhibit the growth of gram-negative bacteria such as Vibrio cholerae and Pseudomonas sp. PnL was also examined for in vitro antifungal activity against six fungal phytopathogens. PnL (100 μg/mL) inhibited the mycelial growth of Alternaria alternata (24.4%). These results indicate that future findings of lectin applications obtained from annelids may be of importance to life sciences. Keywords—Perinereis nuntia, Lectin, Inhibition zone, Mycelial growth.
Modeling and performance analysis of the IEEE 802.11P Enhanced Distributed Channel Access function for vehicular network

The IEEE 802.11p standard drafted to support wireless access in vehicular environments (WAVE) or vehicular ad hoc network (VANET) which uses Enhanced Distributed Channel Access (EDCA) mechanism for the contention-based prioritized Quality of Service (QoS) at the MAC layer. The EDCA mechanism defines four access categories (ACs). Each AC queue works as an independent DCF station (STA) with Enhanced Distributed Channel Access Function (EDCAF) to contend for Transmission Opportunities (TXOP) using its own EDCA parameters. This paper provides an analytical model to compute the performance of the IEEE 802.11p Enhanced Distributed Channel Access Function (EDCAF) for Vehicular Network. To develop the model the four access categories (ACs) and all the major factors that could affect the performance are considered. The relationship among the IEEE 802.11p EDCA parameters and performance matrices are derived through Markov chain based theoretical analysis. Moreover, the derived performance model is verified by simulation.
