Multi-link Operation in IEEE 802.11be WLANs (2022)

The multi-link operation (MLO) is a new feature proposed to be part of the IEEE 802.11be Extremely High Throughput (EHT) amendment. Such feature represents a paradigm shift towards multi-link communications, as nodes will be allowed to transmit and receive data over multiple radio interfaces concurrently. To make it possible, the 802.11be Task Group has proposed different modifications in regards to nodes' architecture, transmission operation, and management functionalities. This article reviews such changes and tackles the question of how traffic should be distributed over multiple links, as it is still unresolved. To that end, we evaluate different load balancing strategies over the active links. Results show that in high load, dense and complex scenarios, implementing congestion-aware load balancing policies to significantly enhance next-generation WLAN performance using MLO is a must.
Genetic associations in type I interferon related pathways with autoimmunity (2010)

Type I interferons play an outstanding role in innate and adaptive immunity by enhancing functions of dendritic cells, inducing differentiation of monocytes, promoting immunoglobulin class switching in B cells and stimulating effector functions of T cells. The increased production of IFNα/β by plasmacytoid dendritic cells could be responsible for not only efficient antiviral defence, but it also may be a pathological factor in the development of various autoimmune disorders. The first evidence of a genetic link between type I interferons and autoimmune diseases was the observation that elevated IFNα activity is frequently detected in the sera of patients with systemic lupus erythematosus, and that this trait shows high heritability and familial aggregation in their first-degree healthy relatives. To date, a number of genes involved in interferon signalling have been associated with various autoimmune diseases. Patients with systemic lupus erythematosus, Sjögren's syndrome, dermatomyositis, psoriasis, and a fraction of patients with rheumatoid arthritis display a specific expression pattern of interferon-dependent genes in their leukocytes, termed the interferon signature. Here, in an attempt to understand the role of type I interferons in the pathogenesis of autoimmunity, we review the recent advances in the genetics of autoimmune diseases focusing on the association of genes involved in type I interferon pathways.
A double-blind evaluation of the effect of amlodipine on ambulatory blood pressure. (1991)

The effects of amlodipine on ambulatory blood pressure were investigated in patients with mild-to-moderate hypertension. Ambulatory recordings showed that amlodipine maintained diastolic and systolic blood pressure below baseline levels for a full 24-h period without altering the normal circadian rhythm. No reflex tachycardia occurred and side effects were rare.
A Study of Socio-Linguistic Aspects of Kin Behaviour Among the Yerukala Tribe in Rayalaseema Region of Andhra Pradesh (2003)

Yerukala is one of the principal tribe groups inhabiting the southern part of the Andhra Pradesh, generally known as Rayalaseema Comprising the revenue of districts of Chittoor, Cuddapah, Anantapur and Kurnool. The Kin behaviour plays an important role in understanding the social structure of a society and the relationship between individuals. There is a close correlation between the language and kin behaviour among the Tribes and one such a tribe is Yerukala of Andhra Pradesh.For the present study Ahobilam, a well known religious place, adjacent to Nallamala forests in Kurnool District is selected. There are altogether 30 kinship terms in Yerukala kinship terminology. Of the 30 terms, 27 are classificatory and the 3 are denotative. It may be pointed out here that the classificatory terms are extended to both consanguineal and affinal kin, including primary kin. Denotative terms, on the other hand, are used exclusively to denote a set of affinal kin. The way of behaviour is expressed towards various kinsmen in terms of Respect Reserved, Informal, Intimate, Avoidance and Joking. The kin behaviour of Yerukala shows consistency with their kinship terminology and marriage practices.

Ferroelectric IR bolometers - from ceramic hybrid arrays to direct thin film integration (1996)

Abstract Bolometer elements in large arrays, at a pitch from 100 down to 40μm, offer uncooled and simple operation in thermal imaging applications. A hybrid array technology, exploiting the pyroelectric property of ferroelectric ceramic materials in the bolometer elements, has produced a range of successful linear and 2-D arrays. High merit for the ceramic has been coupled to fabrication technologies including solder bump bonding of the elements to the multiplexer IC. However, other designs will compete for low costs in the large arrays required for civil applications. In particular, direct deposition of thin film ferroelectric material onto suitable thermal microstructures on the silicon readout IC, could provide substantial reductions in costs and improved performance. This integration will require processes compatible with the silicon IC. Already, lead based perovskite films are showing considerable potential. The successful technology will form the basis for a rapid growth of commercial IR imaging and monitoring into the next century.
The bacterial metabolism of 2,4-xylenol (1968)

1. Measurements of the rates of oxidation of various compounds by a fluorescent Pseudomonas indicated that metabolism of 2,4-xylenol was initiated by oxidation of the methyl group para to the hydroxyl group. 2. 4-Hydroxy-3-methylbenzoic acid was isolated as the product of oxidation of 2,4-xylenol by cells inhibited with alphaalpha'-bipyridyl. 3. 4-Hydroxyisophthalic acid accumulated at low oxygen concentrations when either 2,4-xylenol or 4-hydroxy-3-methylbenzoic acid was oxidized by cells grown with 2,4-xylenol. 4. When supplemented with NADH, but not with NADPH, cell extracts oxidized 4-hydroxy-3-methylbenzoic acid readily. 2-Hydroxy-5-methylbenzoic acid was not oxidized. 5. Both 4-hydroxyisophthalic acid and p-hydroxybenzoic acid were oxidized to beta-oxoadipic acid by cell extracts supplemented with either NADH or NADPH. 4,5-Dihydroxyisophthalic acid was not oxidized. 6. From measurements of oxygen consumed and carbon dioxide evolved it was concluded that protocatechuic acid is an intermediate in the conversion of 4-hydroxyisophthalic acid into beta-oxoadipic acid.
Evaluation of Butyl Rubber as Sorbent Material for the Removal of Oil and Polycyclic Aromatic Hydrocarbons from Seawater (2009)

Ecological disasters resulting from oil spills have created a great need to find more efficient materials for oil spill cleanup. This research highlights the use of a novel macroporous polymeric material based on butyl rubber (BR) as a sorbent in an oil spill cleanup. The sorption capacity of BR for crude oil and petroleum products is 15-23 g g(-1) as compared to the value of 10-16 g g(-1) obtained using a nonwoven polypropylene (PP), a widely used commercial oil sorbent. BR sorbent is reusable after simple squeezing and its continuous sorption capacity for crude oil is 7.6 g g(-1) in each cycle, about 3 times the capacity of the PP sorbent BR sorbents also remove efficiently polycyclic aromatic hydrocarbons (PAHs) such as acenaphthene and pyrene from seawaters. The results suggest that the rubber sorbents are a better alternative to the widely used PP sorbents by improving the efficiency of oil sorption and the reusability of the sorbent.
A Method for Recording Tendon Strain in Sheep During Locomotion (1975)

Strain change in the lateral digital extensor tendon of sheep was measured during locomotion by means of a small metal strain gauge transducer. The strain pattern was correlated with the activity of the muscle and the position of the limb. The main period of tendon strain occurred immediately following a phase of muscle activity as the foot was placed on the ground. A second period of tendon tension occurred as the foot was lifted from the ground. This was again usually associated with a muscular contraction. Daily recordings were taken from 14 animals for about 10 days after implantation of the transducer.

Pyroelectricity enhancement of PVDF nanocomposite thin films doped with ZnO nanoparticles (2014)

A thin film of pyroelectric composite with 0–3 connectivity was fabricated from zinc oxide (ZnO) nanopowder and polyvinylidene fluoride (PVDF) with different volume fraction from 0–0.25 wt%. The dielectric and pyroelectric properties of the samples were investigated. It was found that the presence of a small amount of ZnO nanoparticles (0.25 wt%) has significantly increased the pyroelectric coefficient of the PVDF by 25%. Furthermore, the nanocomposite films required lower poling field to form polar-δ phase compared to pure PVDF thin films. Analysis of the complex permittivity in a wide range of frequency was carried out indicating that the dielectric constant and loss of PVDF/ZnO nanocomposite thin films increase when doped with ZnO. Havriliak-Negami (HN) empirical function has been employed to obtain the α-relaxation time of the nanocomposite thin films before and after poling. The α-relaxation time does not vary with the increase of ZnO wt%; however, the effect of poling has lengthened the relaxation time of the thin films. FTIR and XRD results supports the fact that the addition of ZnO nanoparticles into PVDF polymer thin films do not cause any significant effect on the structure of the PVDF thin films. In fact, ZnO nanoparticle has enhanced the overall pyroelectricity of PVDF by facilitating the poling process in the composites and led to phase transformation of PVDF from α- to δ-phase as supported by a marked reduction of (100) x-ray diffraction intensities.

Simple method for limiting delay of optimised interleaversfor turbo-codes (2000)

The authors propose a simple extension to a previously described iterative interleaver growth algorithm that enables the delay (and required memory) of designed interleavers to be halved with negligible perjormance loss. Low-power implementation of the finite state permutation engine is also described.
[Isolation and physico-chemical properties of homogenous nuclease from Serratia marcescens]. (1980)

A simplified procedure for purification of nuclease from Serratia marcescens, including chromatography on DEAE- and phosphocellulose in a stationary regime has been developed. The method described results in a physically homogenous enzyme, which does not contain phosphatase, phosphodiesterase or proteinase admixtures. The molecular weight of the enzyme as determined by polyacrylamide gel electrophoresis is 33 000 +/- 10%. p-Chloromercurybenzoate (10(-2) M) completely inactivates the enzyme, while beta-mercaptoethanol (0,64 M) in the presence of 2 M urea causes only partial inactivation of the enzyme. Urea (4 or 7 M), when added to the reaction mixture, increases the enzyme activity 2,2-, 1,7- and 1,4-fold as compared to native, denaturated DNA and RNA, respectively.
Trapping-Free Rotors for High-Sealing Lobe Pumps (1999)

In this paper a method for the design of new rotor profiles for high-sealing lobe pump is presented. The objective of this research is to improve the sealing property of lobe pumps by designing chamber profile conforming rotors. The deviation function method is adopted for the design. The resultant rotors are trapping-free and have C1 continuity. A design procedure for rotor generation is also developed. A sealing index is defined to evaluate the sealing property of lobe pumps. Our results show that it is possible to design many new rotor profiles that have better sealing property than conventional involute rotors. [S1050-0472(00)01304-0]
Decision-support tools for foot and mouth disease control (2002)

Recent experience with foot and mouth disease (FMD) has shown that large and very costly epidemics can occur in countries considered extremely unlikely to experience the disease. The consequences of an introduction are much more severe than in the past and effective control is more difficult to achieve. Few countries have developed effective risk management strategies and information-based response systems to respond to these developments. The authors describe the tools which can be employed to minimise the impact of a disease incursion, using the example of FMD. To make such systems effective, the development of a national farms database in advance, including geo-referencing, is highly desirable. This greatly enhances the power of the decision-support tools, which can then be applied as soon as a serious disease incursion has been detected. These tools include procedures to detect infected farms promptly, to protect as yet uninfected farms against exposure to virus and to manage control policies. Epidemiological evaluation and prediction tools have advanced particularly rapidly and can guide the choice of control policies during an outbreak. Integrated decision-support systems offer the best method of managing FMD outbreaks to minimise the cost and size of the epidemics.
Sparse superpixel unmixing for exploratory analysis of CRISM hyperspectral images (2009)

Fast automated analysis of hyperspectral imagery can inform observation planning and tactical decisions during planetary exploration. Products such as mineralogical maps can focus analysts' attention on areas of interest and assist data mining in large hyperspectral catalogs. In this work, sparse spectral unmixing drafts mineral abundance maps with compact reconnaissance imaging spectrometer (CRISM) images from the Mars Reconnaissance Orbiter. We demonstrate a novel ldquosuperpixelrdquo segmentation strategy enabling efficient unmixing in an interactive session. Tests correlate automatic unmixing results based on redundant spectral libraries against hand-tuned summary products currently in use by CRISM researchers.
Wages, Hiring Standards, and Firm Size (1984)

We present a model of firm behavior in which firms choose a wage and a hiring standard to maximize their profits. The correlation between productivity and reservation wage affects the relationship among firm size, wages, and hiring standards. In the special case where labor productivity is a linear function of a worker's reservation wage, we find that in the absence of hiring costs wages are monotonically increasing with firm size. Any positive hiring costs, however, result in an interval of sufficiently small firms within which wages decrease with firm size. In all cases, among sufficiently large firms, wages increase with firm size. A review of previous empirical evidence finds that in some occupations the relationship between wages and firm size is U-shaped, while in other occupations wages increase monotonically with firm size. These empirical findings are consistent with our theoretical results.
Design of Boeing 777 electric system (1992)

The electric power system for the Boeing 777 is comprised of two independent electrical systems, the main and the backup. The main electric system includes two engine-driven integrated drive generators, a generator driven by the auxiliary power unit, three generator control units, and a bus power control unit. The backup electric system includes two engine-drive generators and one integrated converter/control unit to provide the redundancy of electrical sources equivalent to a three-engine airplane. Automation of the system is achieved by the use of state-of-the-art, microprocessor-based control units that perform system control, protection, and built-in-test functions. Each control unit has redundant two-way communication through an ARINC 629 communication bus that requires significantly fewer discrete wires than similar systems, allowing considerable reduction of the interface circuits and reduction in weight.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Know-Evolve: Deep Temporal Reasoning for Dynamic Knowledge Graphs (2017)

The availability of large scale event data with time stamps has given rise to dynamically evolving knowledge graphs that contain temporal information for each edge. Reasoning over time in such dynamic knowledge graphs is not yet well understood. To this end, we present Know-Evolve, a novel deep evolutionary knowledge network that learns non-linearly evolving entity representations over time. The occurrence of a fact (edge) is modeled as a multivariate point process whose intensity function is modulated by the score for that fact computed based on the learned entity embeddings. We demonstrate significantly improved performance over various relational learning approaches on two large scale real-world datasets. Further, our method effectively predicts occurrence or recurrence time of a fact which is novel compared to prior reasoning approaches in multi-relational setting.
Method and utility for recovering code algorithms of telecommunication devices for vulnerability search (2014)

The article describes a method for searching vulnerabilities in machine code based on the analysis of its algorithmized representation obtained with the help of an utility being a part of the method. Vulnerability search falls within the field of telecommunication devices. Phase-by-phase description of the method is discussed, as well as the software architecture of the utility and their limitations in terms of application and preliminary effectiveness estimate results. A forecast is given as to developing the method and the utility in the near future.
An array-compensated spherical reflector antenna for a very large number of scanned beams (2005)

There are many stringent demands imposed on the applications of spaceborne antenna systems. One of the most challenging demands is the generation of multiple beams with the ability to scan a very large number of beamwidths. Since the parabolic reflectors have limitations in this application, a 35-m spherical reflector antenna is proposed for a geostationary radar antenna at Ka-band (35.6 GHz) due to its inherent capability of scanning the beams to very large number of beamwidths. The utility of using planar array feeds for correcting spherical phase aberrations is investigated to overcome the performance degradation effects. Two different methodologies are developed for the array excitation coefficients determination based on phase conjugate matching and the results are compared. Using the compensating feed array, the radiation characteristics of the compensated spherical reflector are simulated for no scan and large scan cases and the results are compared with the uncompensated case to show performance improvement. In order to demonstrate the technological readiness of the concept a 1.5-m breadboard model is designed to be built for experimental measurements. Some important mechanical design tolerances and realistic array feed topologies are investigated. The antenna concept developed in this paper is advocated to be used in the next generation of geostationary satellite antenna systems for remote sensing radar applications.
ICMP Attacks against TCP (2010)

This document discusses the use of the Internet Control Message Protocol (ICMP) to perform a variety of attacks against the Transmission Control Protocol (TCP). Additionally, this document describes a number of widely implemented modifications to TCP's handling of ICMP error messages that help to mitigate these issues.
Transplantation of hematopoietic progenitor cells with emphasis on the results in children. (1995)

Attempted human allogeneic marrow transplants in the 1950's and 60's were largely unsuccessful. In the past two decades the probability of success has improved steadily depending on the type and stage of disease. All marrow transplant teams have observed that the results for children are better than for adults. Long-term survival and apparent cure rates range from about 90 percent for non-malignant diseases transplanted early to 15 percent for patients with advanced leukemia. Most marrow transplants have involved an HL-A matched sibling donor but, more recently, through the worldwide marrow donor registries a matched unrelated volunteer marrow donor can be found for many patients without a family donor. Current research involves new preparative regimens for elimination of malignant cells, better prevention of graft-versus-host disease (GVHD), and the use of hematopoietic growth factors and cytokines. Autologous transplants, which use the patient's own marrow, are increasing. The hematopoietic stem cell, which is responsible for marrow regeneration after a transplant, has been isolated and characterized. Stem cells for transplantation can now be obtained from the peripheral blood after mobilization of these cells by chemotherapy or hematopoietic growth factors.
