title: Genetic diversity and evolution of hepatitis C virus
Creators: name: Harris, Kathryn Ann
Publisher: name: The Open University
Year: 2000

description: Inter- and intra-host Hey variation was investigated. First. a polymerase chain reactionrestriction fragment length polymorphism procedure was used to assign genotypes and subtypes to Hey infecting 567 individuals (comprising haemophilia patients, blood donors, intravenous drug users, attenders of antenatal and genito-urinary medicine clinics and chronic liver disease patients) from England and Wales. The majority of infections were associated with types 3a, 1 a and 1 b, and genotype distributions were generally similar in different sub-populations. Only 1 % of individuals were identified as being infected with more than one subtype. The intra-host variability of Hey in a selection of haemophilia patients, blood donors and intravenous drug users was then studied. For each individual, peR clones derived from the NS5b and 5' non-coding regions of the Hey genome were screened for sequence differences by denaturing gradient gel electrophoresis (DGGE) and nucleotide sequencing. The complexity and diversity of Hey quasi species, though differing between individuals, could not be correlated with the risk group to which the study patients belonged. Furthermore, no mixed genotype or subtype infections were identified. Thus the hypothesis that multiply exposed individuals are infected with a greater variety of HCY variants could not be substantiated. The DGGE procedure was further used to investigate the hypothesis that HCY genetic evolution occurs uniformly in patients during the acute phase of infection. Changes in diversity in the HCY hypervariable region 1 in individuals undergoing seroconversion were observed to differ between patients, thereby negating that hypothesis. Moreover, in a given individual, Hey could be subjected to either positive or negative selective pressure. Thus, factors other than the acute-phase host response determine the course of Hey genetic evolution.

description: Abstract: The long-term goals of fen restoration include climate, water, and natural areas protection. Depending on the characteristics of fen under consideration (size, landscape position, previous land use, current land use, presence of livestock), conflicts can arise as to which re-wetting strategies are most appropriate. These conflicts can be largely avoided by taking into account the following considering prior to fen re-wetting: (1) Restoration of large and highly degraded fens is mainly focused on climate protection (prevention of CO2 emission) and on reduction of nitrate non-point pollution of surface waters; whereas issues of potentially enhanced phosphorus export into adjacent surface waters and nature protection are only of minor importance. (2) Smaller and less degraded fens with an important current or potential livestock should be re-wetted with care under the point of view of nature protection. The re-wetting should be accompanied by biomass removal to support nutrient-poor conditions. (3) Particular care is needed if the fen is situated in a catchment with nutrient-poor lakes. In such cases, the risk of enhanced P export due to fen-rewetting must be minimised.
description: Zusammenfassung: Aus langfristiger Sicht erfüllt eine Restaurierung von Niedermooren mit dem Ziel eines erneuten Moorwachstums alle Anforderungen der Aspekte Klimaschutz, Gewässerschutz und Naturschutz. In Abhängigkeit von der Ausgangssituation (Größe der Flächen, Einbettung in der Landschaft, vorangegangene Nutzungsintensität, noch vorhandenes moortypisches Arteninventar) und der Managementvariante der geplanten Wiedervernässung kann es in der Anfangsphase einer Moorrestaurierung zu konkurrierenden Zielstellungen kommen. Diese lassen sich jedoch schon in der Planungsphase vermeiden, wenn folgende Grundsätze berücksichtigt werden: (1) Die Restaurierung großer, stark degradierter Niedermoore kann in erster Linie mit Klimaschutzzielen (=CO2-Emissionsvermeidung) und mit Gewässerschutzzielen zum Nitratrückhalt begründet werden; Fragen potenziell erhöhter Austräge von Phosphor (P) in Gewässer und der (konservative) Naturschutz spielen in der Regel eine untergeordnete Rolle. (2) Kleinere, weniger degradierte Moore mit einem bedeutendem aktuellen oder potenziellen Arteninventar müssen aus der Sicht des Naturschutzes mit einem angepassten Management (z. B. vorsichtige Wasserstandsanhebung ohne Überstauung, Biomasseentzug) restauriert werden. (3) Besondere Vorsicht ist bei Moorwiedervernässungen gegeben, wenn im Abstrombereich nährstoffarme Seen liegen. In diesem Falle ist das Risiko erhöhter P-Austräge infolge der Restaurierungsmaßnahmen zu minimieren.

title: The foreign architectural book society and architectural elitism
Creators: name: Horton, Ian Peter
Publisher: name: The Open University
Year: 2000

description: This study investigates the Foreign Architectural Book Society [F. A. B. S. ] and its members from its foundation in 1859 through to the 1930s. Particular attention is given to the second generation of F. A. B. S. members, active between 1890 and 1920, who shared scholarly interests apparent in the architectural values they promoted in publications and their own buildings. In this period these F. A. B. S. members also occupied positions of power within the profession and influenced their contemporaries by encoding Beaux-Arts values in a reformed architectural education system. These developments are analysed using certain aspects of elite theory: this highlights the protectionist aspects of this education system and explains the survival into the 1930s of architectural values promoted by F. A. B. S. members. The F. A. B. S. was founded with the intention of internally circulating foreign architectural books and this study examines how the society operated. The functioning of the F. A. B. S is analysed in relation to other societies its members joined, establishing their high social standing and a network of scholarly organisations through which architectural values were formed. An analysis of publications and buildings by the second generation of F. A. B. S. members reveals the fact that they promoted two architectural styles, Neo-Wrenaissance and Monumental Classicism. It is argued that Wren's influence was central to the formation of the values embodied in these styles. In the case of the Neo- Wrenaissance it is shown that this is a more appropriate term to describe works usually noted as examples of Neo-Georgian architecture. When examining Monumental Classicism it is noted that F. A. B. S. members used Beaux-Arts compositional devices, as encoded in architectural education, but promoted it as a national style by invoking the example of Wren. In conclusion it was argued that F. A. B. S. members encoded these stylistic values in the reformed architectural education system and this partially explains how the outmoded values of the Neo- Wrenaissance and Monumental Classicism managed to survive as valid stylistic options until the end of the 1930s.

description: Transmission line failure in power systems prop-agate non-locally, making the control of the resulting outages extremely difficult. In Part II of this paper, we continue the study of line failure localizability in transmission networks and characterize the impact of cut set outages. We establish a Simple Path Criterion, showing that the propagation pattern due to bridge outages, a special case of cut set failures, are fully determined by the positions in the network of the buses that participate in load balancing. We then extend our results to general cut set outages. In contrast to non-cut outages discussed in Part I whose subsequent line failures are contained within the original blocks, cut set outages typically impact the whole network, affecting the power flows on all remaining lines. We corroborate our analytical results in both parts using the IEEE 118-bus test system, in which the failure propagation patterns exhibit a clear block-diagonal structure predicted by our theory, even when using full AC power flow equations.

description: We use the isotropy of the Cosmic Microwave Background to place stringent constraints on a possible electrical charge asymmetry of the universe. We find the excess charge per baryon to be $q_{e-p}<10^{-26}e$ in the case of a uniform distribution of charge, where $e$ is the charge of the electron. If the charge asymmetry is inhomogeneous, the constraints will depend on the spectral index, $n$, of the induced magnetic field and range from $q_{e-p}<5\times 10^{-20}e$ ($n=-2$) to $q_{e-p}<2\times 10^{-26}e$ ($n\geq 2$). If one could further assume that the charge asymmetries of individual particle species are not anti-correlated so as to cancel, this would imply, for photons, $q_γ< 10^{-35}e$; for neutrinos, $q_ν<4\times10^{-35}e$; and for heavy (light) dark matter particles $q_{\rm dm}<4\times10^{-24}e$ ($q_{\rm dm}<4\times10^{-30}e$).

description: Abstract: In 2010 the assemblages of the Lepidoptera and selected groups of merolimnic insects in the bog “Teufelsmoor near Gresenhorst” were examined. The goal was to conclude by bioindication on ecological deficits. The method of Standorttypieindex, the ecological profiles and preferences of discovered species due to hygrophila and the food plants were used. It was found that the bog still has a high regeneration potential. The habitat deficits mainly lie in a mild disorder of water balance, in the structural deficits of Lagg, in the lack of forest wane and the surrounding coniferous forests. It can be derived proposals for ecological restoration projects.
description: Zusammenfassung: Im Jahre 2010 wurden die Vergesellschaftungen der Lepidopteren und ausgewählte Gruppen merolimnischer Insekten im Teufelsmoor bei Gresenhorst untersucht. Ziel war es, mittels Bioindikation ökologische Defizite zu ermitteln. Dazu kamen der Standorttypieindex, die ökologischen Profile sowie Präferenzen nachgewiesener Arten bezüglich Hygophilie und Fraßpflanzen zur Anwendung. Es konnte festgestellt werden, dass das Moor noch ein hohes Regenerationspotential hat. Die Naturraumdefizite sind vorwiegend in leichten Störungen des Wasserhaushaltes, in der Trockenlegung und teilweisen Aufforstung des Laggs, im fehlenden natürlichen Waldmantel und den umgebenden Nadelforsten begründet. Die Ergebnisse werden im Zusammenhang mit der geologischen Entstehung des Moores dargestellt und diskutiert. Es werden Vorschläge für ökologische Sanierungen abgeleitet.

description: In today's scenario, going beyond Einstein's theory of gravity leads us to some more complete and modified gravity theories. One of them is the $f(R,T)$ gravity in which $ R $ is the Ricci scalar, and $ T $ is the trace of the energy-momentum tensor. Using a well-motivated linear $f(R,T)$ gravity model with a single parameter, we studied the strong energy condition (SEC), the weak energy condition (WEC), the null energy condition (NEC), and the dominant energy condition (DEC) under the simplest non-minimal matter geometry coupling with a perfect fluid distribution. The model parameter is constrained by energy conditions and a single parameter proposed equation of state (EoS), resulting in the compatibility of the $f(R,T)$ models with the accelerated expansion of the universe. It is seen that the EoS parameter illustrate the quintessence phase in a dominated accelerated phase, pinpoint to the cosmological constant yields as a prediction the phantom era. Also, the present values of the cosmological constant and the acceleration of the universe are used to check the viability of our linear $f(R,T)$ model of gravity. It is observed that the positive behavior of DEC and WEC indicates the validation of the model. In contrast, SEC is violating the condition resulting in the accelerated expansion of the universe.

title: An examination of the effects of thalamic lesions on learning and memory in the rat
Creators: name: Hunt, Peter Richard
Publisher: name: The Open University
Year: 2000

description: The study examined the effects of lesions of the thalamic nucleus medialis dorsalis (MD) made by neurotoxin in three cohorts ofrats to help understand the contribution of this nucleus to learning and memory. The lesions typically provided comprehensive damage to . MD, while the use of an excitotoxin helped to minimise damage to fibres of passage or adjacent fibre tracts. This excluded one confounding influence that may have been present in some previous studies. Some MD lesions also affected the anterior thalamic nuclei, and this additional damage led to spatial memory impairments, helping to confirm the value of results from rats with lesions confined to MD. Whilst the groups with MD lesions were largely unimpaired on non-spatial tests of visual recognition and discrimination, they were impaired on a configural discrimination task. The MD lesions did not impair spatial nonmatching to sample in aT-maze, nor the acquisition or performance over delay conditions of the standard radial maze task. There were impairments, however, when the radial maze was rotated during the delay, requiring a strategy shift. Similar impairment was found when a matching, rather than non-matching, strategy was required on the T-maze task and also when only some arms were rewarded on the radial arm maze task for reference memory measurement. No impairment was seen when the T-maze matching task was reversed to the non-matching variant, emphasising the lesion rats' preference for preexisting rules. In addition, some evidence was found that MD lesions brought about increased activity, but had no effect on conditioned place preference. The study concludes that MD damage in rats does not directly cause memory deficits. The influence that MD damage has on memory is, however, similar to that associated with damage to prefrontal cortex causing deficits in rule-switching ability, a higher order frontal lobe function .

description: The ability to predict and/or control wall slip is a fundamental problem in the hydrodynamics of yield stress fluids, which is poorly understood to date and has important applications in bio- and micro-fluidic systems. Systematic measurements of steady flows of a simple yield stress fluid (Carbopol Ultrez 10) in a plane acrylic micro-channel are used to establish rigorous scaling laws for the wall velocity gradient and the slip velocity. By means of epi-fluorescent microscopy combined with a custom developed Digital Particle Image Velocimetry (DPIV) technique, times series of velocity fields were measured within a wide range of flow rates and three distinct flow regimes were identified: full plug, partial plug and fully yielded. Corresponding to each flow regime, wall velocity gradients and slip velocities were obtained by extrapolating the velocity profiles using a smoothing spline function. By combining the flow field measurements with the macro-rheological measurements, scaling laws for the wall velocity gradient and the slip velocity with the wall shear stress were identified, and compared with results from the literature. Detailed microscopic measurements of the velocity field enabled an assessment of the effectiveness of a chemical treatment of the channel walls meant to suppress wall slip proposed by Metivier and coworkers in Ref. [1].

description: Abstract: Considerable changes in plant sociological, pedologic and hydrologic conditions has been observed, due to a deep drainage ditch, surrounding the bog and separating it from his 655 ha large watershed. The original area of the bog was 150 ha with a remaining original vegetation of 3 ha. The thickness of the peat decreased in the last 30 years around 0.4 m and in total 1.5 m since drainage succeeded. The ground water level varies around 0.6 m below surface in the most areas of the bog, which are overgrown with Rubus fruticosus - Molinia caerulea- Pinus sylvestris or Betula pubescens – forests, respectively. To preserve the left original vegetation of the bog we propose rewetting by maximum possible water retention without flooding.
description: Zusammenfassung: Durch einen tiefen Entwässerungsgraben, der das Moor vollständig umgibt, wurden Vegetation, Moormächtigkeit und hydrologische Verhältnisse erheblich verändert. Von dem 150 ha großen Regenmoor mit einem Einzugsgebiet von 655 ha ist nur eine 3 ha große Fläche mit typischer Regenmoorvegetation und moortypischen flurnahen Wasserständen erhalten geblieben. Seit 1938 ist ein Höhenverlust der Mooroberfläche von 1,5 m nachgeweisen. Allein in den letzten 30 Jahren sank die Mooroberfläche um 0,4 m. In weiten Teilen des Moores sinken die Grundwasserflurabstände jetzt bis 60 cm unter Flur ab. In diesen Bereichen ist das Moor mit Brombeer- oder Pfeifengras-Kiefern- bzw. Moorbirkenwald bewachsen. Um die zentrale Hochmoorfläche mit ihrer annähernd ursprünglichen Artenzusammensetzung zu erhalten, wird ein maximal möglicher Einstau vorgeschlagen.

description: A high-accuracy multisite campaign was carried out from 2002 January to May with a photometric coverage of 398 hours at five observatories. The concentration on a few selected sites gives better consistency and accuracy than collecting smaller amounts from a larger number of sites. 23 frequencies were detected with a high statistical significance. 6 of these are new. The 17 frequencies found in common with the 1992-1995 data are the modes with highest amplitudes. This indicates that the pulsation spectrum of FG Vir is relatively stable over the ten-year period. Two frequencies have variable amplitudes and phases from year to year as well as during 2002. These were both found to be double modes with close frequencies. For the mode at 12.15 c/d this leads to an apparent modulation with a time scale of about 129d. The close frequencies at 12.15 c/d are composed of a radial and a nonradial mode, suggesting a similarity with the Blazhko Effect seen in RR Lyrae stars.

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: In this paper R-Theta Local Neighborhood Pattern (RTLNP) is proposed for facial image retrieval. RTLNP exploits relationships amongst the pixels in local neighborhood of the reference pixel at different angular and radial widths. The proposed encoding scheme divides the local neighborhood into sectors of equal angular width. These sectors are again divided into subsectors of two radial widths. Average grayscales values of these two subsectors are encoded to generate the micropatterns. Performance of the proposed descriptor has been evaluated and results are compared with the state of the art descriptors e.g. LBP, LTP, CSLBP, CSLTP, Sobel-LBP, LTCoP, LMeP, LDP, LTrP, MBLBP, BRINT and SLBP. The most challenging facial constrained and unconstrained databases, namely; AT&T, CARIA-Face-V5-Cropped, LFW, and Color FERET have been used for showing the efficiency of the proposed descriptor. Proposed descriptor is also tested on near infrared (NIR) face databases; CASIA NIR-VIS 2.0 and PolyU-NIRFD to explore its potential with respect to NIR facial images. Better retrieval rates of RTLNP as compared to the existing state of the art descriptors show the effectiveness of the descriptor

description: In a number of astrophysical applications one tries to determine the two-dimensional or three-dimensional structure of an object from a time series of measurements. While most methods used for reconstruction assume that object is static, the data are often acquired over a time interval during which the object may change significantly. This problem may be addressed with time-dependent reconstruction methods such as Kalman filtering which models the temporal evolution of the unknown object as a random walk that may or may not have a deterministic component. Time-dependent reconstructions of a hydrodynamical simulation from its line-integral projections are presented. In these examples standard reconstructions based on the static assumption are poor while the Kalman based reconstructions are of good quality. Implications for various astrophysical applications, including tomography of the solar corona and radio aperture synthesis, are discussed.

An analysis of the assumptions made in these models is provided here, and six fundamental results concerning these transformations are contributed as follows: (i) Softened phonon modes produce rotational modes in these materials. (ii) The transformation to a structure with P4/nmm symmetry occurs at the lowest critical temperature $T_c$. (iii) The hypothesis that one unidirectional optical vibrational mode underpins the 2D transformation is unwarranted.

These data are collected during the common operation time, which cover ten activity phases of Mrk 421. No significant ALP-photon oscillation effect is confirmed. On the other hand, not all the observations of the ten phases can be individually used to set the 95% confidence level ($\rm C.L.$) constraint on the ALP parameter space. However, the constraint can be significantly improved if the analyses for the ten phases are combined. We find that the upper limit at 95% $\rm C.L.$ on the ALP-photon coupling $g_{aγ}$ set by the ARGO-YBJ and Fermi-LAT observations of Mrk 421 is within $\sim [2\times 10^{-11}, \ 6\times 10^{-11}] \rm \, GeV^{-1}$ for the ALP mass of $\sim 5\times 10^{-10}$ eV $\lesssim m_a \lesssim 5\times 10^{-7}\, \rm eV$.

description: Local descriptors used in face recognition are robust in a sense that these descriptors perform well in varying pose, illumination and lighting conditions. Accuracy of these descriptors depends on the precision of mapping the relationship that exists in the local neighborhood of a facial image into microstructures. In this paper a local gradient hexa pattern (LGHP) is proposed that identifies the relationship amongst the reference pixel and its neighboring pixels at different distances across different derivative directions. Discriminative information exists in the local neighborhood as well as in different derivative directions. Proposed descriptor effectively transforms these relationships into binary micropatterns discriminating interclass facial images with optimal precision. Recognition and retrieval performance of the proposed descriptor has been compared with state-of-the-art descriptors namely LDP and LVP over the most challenging and benchmark facial image databases, i.e. Cropped Extended Yale-B, CMU-PIE, color-FERET, and LFW. The proposed descriptor has better recognition as well as retrieval rates compared to state-of-the-art descriptors.

Publisher: name: Zenodo
Year: 2024

description: This deliverable reviews the state-of-the-art in methods for conducting impact assessments (IAs) in the security area. We give particular attention to methods for assessing the impact of security technologies on ethics, human rights (including privacy and data protection), as well as social and economic well-being. With respect to the security area, we give particular attention to four domains - cybersecurity, disaster resilience, fighting crime and terrorism, and border management. Following introductions and explanation of methodology, chapter 3 conveys an overview of key doctrines that could be seen as underlying the decision to conduct IAs, especially in the security technologies' area. Then, chapter 4 deconstructs and analyses the building blocks of an impact assessment exercise, applicable to each sub-type of an IA. This leads to the core part of the deliverable - chapter 5 - divided on key impact assessment subcategories; for each subcategory, a description is provided, together with a breakdown of leading and relevant impact assessment frameworks. Chapter 6 moves on to provide an analysis of factors and challenges that might appear when conducting IAs within each of the four indicated domains of security. Chapter 7 enhances the report with description and analysis of findings from two surveys conducted by the TRANSCEND project, aimed at discovering the use of IAs among the security industry and local authorities. Chapter 8 puts forward conclusions and recommendations, centred around the need to provide accessible information about the landscape of impact assessment methodologies to all interested stakeholders.

description: Derrick's theorem is an important result that decides the existence of soliton configurations in field theories in different dimensions. It is proved using the extremization of finite energy of configurations under the scaling transformation. According to this theorem, the $2+1$ dimension is the critical dimension for the existence of solitons in scalar field theories without the gauge fields. In the present article, Derrick's theorem is extended in a generic curved spacetime in a covariant manner. Moreover, the existence of solitons in conformally flat spacetimes and spherically symmetric spacetimes is also shown using the approach presented in this article. Further, the approach shown in the present article in order to derive the soliton configurations is not restricted to a particular form of the field potential or curved spacetime.

title: The life and works of Jeremiah Joyce
Creators: name: Issitt, John
Publisher: name: The Open University
Year: 2000

description: This thesis traces the life and works of Jeremiah Joyce (1763-1816). Chapter 1 introduces Joyce and presents the methodology applied in the production of the thesis. Chapter 2 traces his upbringing as a Presbyterian dissenter and his experiences as a glazier's apprentice in Georgian London. It also gives an account of the influence of Arian and Unitarian teachers on Joyce and the education he received at Hackney College. Chapter 3 records Joyce's activities in radical metropolitan societies and his involvement in the 1794 Treason Trials. Chapter 4 explores Joyce's early writings produced whilst in the employment of the Earl of Stanhope. Chapter 5 gives an account of Joyce's life as a jobbing author in the first sixteen years of the nineteenth century. Chapter 6 is the largest chapter and traces Joyce's works. The chapter is organised around Joyce's publishers and explores his many titles, some of which were published under pseudonyms. It probes the nature of Joyce's work as a writer, compiler and editor, and the different strategies he used to present scientific knowledge. It also traces the compromises between the theological, pedagogical and commercial concerns which dictated the form and content of the works. The thesis is concerned to resurrect Joyce as an interesting figure whose importance as a political activist and science educationalist has hitherto been overlooked. His life and work is cast against the influences of the French Revolution on British society. In the early 1 790s, Joyce was engaged in political education and the distribution of radical literature. From the later 1790s, his energies were focused on science education. The thesis traces this transition as revealed in Joyce's personal history and literary output.

description: Abstract: Within the Saxonian lowlands transitional bogs, moor waters and lowland spruce forests are spread especially in the natural regions „Oberlausitzer Heide- und Teichgebiet“, „Muskauer Heide“ and „Königsbrück-Ruhlander Heiden“. Situated in the transitional area to the natural region „Westlausitzer Hügel- und Bergland“ the forest peat bogs in the der Laußnitzer und Radeburger Heide at the southwestern edge of the „Königsbrück-Ruhlander Heiden“ are characterized by several particularities. The occurrence of biotopes and species that are rare and worthy of protection was the reason for the establishment of the two nature reserves „Moorwald am Pechfluss bei Medingen“ and „Waldmoore bei Großdittmannsdorf“, but also for the notification of NATURA 2000 areas.

description: The aim of the paper was to present main premises of using non-tariff instruments of trade policy and prevalence of administrative barriers in agriculture sector. Those premises are due to economic, political and social influences. The literature review notes that prices and income in agriculture are the basis of those premises and are aimed at both protecting the agriculture sector and strengthening the internal market. The data by the WTO on scale and scope of the trade defense instruments shows that the most common instruments are sanitary and phytosanitary standards (SPS) as well as technical barriers to trade (TBT). It also shows that the continent with the greatest use of the non-tariff instruments of trade policy is Asia.

description: We present two BeppoSAX observations of BL Lac (2200+420) as part of a multiwavelength campaign performed in 2000. The source was in different states of activity: in June, the X-ray spectrum was faint and hard (alpha sim 0.8), with positive residuals towards low energies. In October we detected the highest [2-10] keV flux ever measured for the source. During this observation, the spectrum was soft (alpha sim 1.56) up to 10 keV, while above this energy a hard component was dominating. The BeppoSAX data are confirmed by simultaneous RXTE short observations. During the first observation the soft X-ray flux was variable on timescales of a few hours, while the hard X-ray flux was almost constant. During the second observation, instead, the soft spectrum displayed an erratic behaviour with large variations (up to factors 3-4) on timescales smaller than 2 hrs. The analysis of the multiwavelength SED of October evidenced an intriguing feature: the optical and X-ray sections of the SED are misaligned, while in the prevailing standard picture, they are both thought to be produced via synchrotron emission. We suggested four scenarios to account for this discrepancy: a higher than galactic dust-to-gas ratio towards the source, the first detection of bulk Compton emission in the X-ray band, the presence of two synchrotron emitting regions located at different distances from the nucleus, the detection of a Klein-Nishina effect on the synchrotron spectrum. We evidenced the favorable and critical points of each scenario, but, at present, we cannot discriminate between them.

description: Feature description is one of the most frequently studied areas in the expert systems and machine learning. Effective encoding of the images is an essential requirement for accurate matching. These encoding schemes play a significant role in recognition and retrieval systems. Facial recognition systems should be effective enough to accurately recognize individuals under intrinsic and extrinsic variations of the system. The templates or descriptors used in these systems encode spatial relationships of the pixels in the local neighbourhood of an image. Features encoded using these hand crafted descriptors should be robust against variations such as; illumination, background, poses, and expressions. In this paper a novel hand crafted cascaded asymmetric local pattern (CALP) is proposed for retrieval and recognition facial image. The proposed descriptor uniquely encodes relationship amongst the neighbouring pixels in horizontal and vertical directions. The proposed encoding scheme has optimum feature length and shows significant improvement in accuracy under environmental and physiological changes in a facial image. State of the art hand crafted descriptors namely; LBP, LDGP, CSLBP, SLBP and CSLTP are compared with the proposed descriptor on most challenging datasets namely; Caltech-face, LFW, and CASIA-face-v5. Result analysis shows that, the proposed descriptor outperforms state of the art under uncontrolled variations in expressions, background, pose and illumination.
