Unconventional Pattern Research Articles

Society and people

Science and philosophy has a strong polar division from the very beginning of human civilization. People have been using the both to tackle down the issues and troubles of the society, domesticity and of personal levels. While the western has been seeking, practical solutions to the problems through science, The Arabs in spite of internal turbulence and external pressure have retained their strong individuality preferred to look at life in poetic and philosophical terms. The Arab has a dominance of religious biasness instead of scientific developments. The writers from the area also respected the same and have captured the spirit of masses, portraying their devotion to home and their blind fidelity to their rules. Arab writers have left freedom of expression with their own unconventional pattern and no amount of outside pressure or criticism has been able to divert them from it. The social, political and religious issues were very widely discussed in the works of some Arabic writers. One of the most notable one is Jibran Khalil Jibran, the paper aims to explore these social concerns through his one of most celebrated short story collections- “ "عرائس المروج "Nymphs of the Valley”.

Serology study after BTN162b2 vaccination in participants previously infected with SARS-CoV-2 in two different waves versus na\xefve

BackgroundThe antibody response to SARS-CoV-2 mRNA vaccines in individuals with waning immunity generated by a previous SARS-CoV-2 infection, as well as the patterns of IgA and IgM responses in previously infected and in naïve individuals are still poorly understood.MethodsWe performed a serology study in a cohort of BTN162b2 mRNA vaccine recipients who were immunologically naïve (N, n = 50) or had been previously infected with SARS-CoV-2 (P.I., n = 51) during the first (n = 25) or second (n = 26) pandemic waves in Italy, respectively. We measured IgG, IgM and IgA antibodies against the SARS-CoV-2 Spike (S) and IgG against the nucleocapsid (N) proteins, as well as the neutralizing activity of sera collected before vaccination, after the first and second dose of vaccine.ResultsMost P.I. individuals from the first pandemic wave who showed declining antibody titres responded to the first vaccine dose with IgG-S and pseudovirus neutralization titres that were significantly higher than those observed in N individuals after the second vaccine dose. In all recipients, a single dose of vaccine was sufficient to induce a potent IgA response that was not associated with serum neutralization titres. We observed an unconventional pattern of IgM responses that were elicited in only half of immunologically naïve subjects even after the second vaccine dose.ConclusionsThe response to a single dose of vaccine in P.I. individuals is more potent than that observed in N individuals after two doses. Vaccine-induced IgA are not associated with serum neutralization.

Aesthetic of African Arts Features and Colors in innovating Design Contemporary Woven Wall hangings

African Arts is distinct from other arts, with its dazzling colors, and it is characterized by simplicity and influenced by the customs and traditions of tribes in the desert and African forests. It contains the methods used in the implementation of floor covering and including : manual and mechanical methods . African arts differ greatly from the arts in the world, as they always have real-life connotations in Africa in terms of heat, work and effort, and are embodied in dazzling colors and sometimes in an unconventional pattern in the formations of bodies and shapes, so African art is always distinguished from other arts by its dazzling colors and Warmth in expressing the subject of the artistic work as it is an art characterized by simplicity and its abstractions, and we find that African art has had a great influence on the arts of the modern and contemporary times. The assets in their artistic works, especially the Surrealist and Cubist school. Weavs wall were chosen to apply this art because this industry is one of the types of textile industries that are closely related to art and technology, as it is one of the industries that most show the customs and traditions of peoples through designs through which we can identify the customs and traditions of different peoples as it is an important means To learn about the civilizations of different nations. Research problem: That in light of the country’s current orientation to Africa, this research will enrich African art and create designs inspired by it to be marketed globally and locally. Research objectives: Creating designs that can be used as weaving pendants, inspired by some African art units and symbols, to be executed in the Hand Tuft style. Significance : 1- Utilizing the units and colors of African art in creating designs for textile pendants. 2- Enriching the textile industry by using African art units and colors. 3- Support state directives, limit the consolidation of relations with African countries. Conclusion : 1- African art units can be used to create modern designs with aesthetic values and to use them as weaves wall object. 2- The use of different colors using the same design helped to obtain many aesthetic effects, which helps to satisfy all tastes. 3-Using the hand tufting method to implement the designs and the possibility of making a prominent and clear way to embody and clarify some elements from others.

Rare Distal Metastasis of Endometrial Adenocarcinoma Impersonating as Primary Colon Cancer.

An 89-year-old Caucasian female with a recent diagnosis of endometrial adenocarcinoma status post hysterectomy and acute deep vein thrombosis on anticoagulation presented with hematochezia. Colonoscopy revealed sigmoid colon stricture with the biopsy findings of metastatic endometrial adenocarcinoma based on positive immunohistochemistry staining for cytokeratin 7, paired box gene 8, and estrogen receptor. The oncologist referral was given to the patient for consideration of chemotherapy, but she decided to go with palliative care. Thus far, only 2 similar cases have been published in the literature. Our case exemplifies the potential for an unconventional pattern of metastasis of primary endometrial adenocarcinoma to the colon.

Looking for Zebras: Unexpected Solutions to Pattern Tasks

Creating ambiguity in task prompts can encourage students to identify unconventional pattern extensions.

Unconventional topological insulators from extended topological band degeneracies

A general and beautiful picture for the realization of topological insulators is that the mass term of the Dirac model has a nodal surface wrapping one Dirac point. We show that this geometric picture based on Dirac points can be generalized to extended band degeneracies with nontrivial topological charges. As the nontrivial topological charges force the extended band degeneracies to be created or annihilated in pairs, when the nodal surface of mass wraps one such extended band degeneracy, the resulting gapped phase must be topologically nontrivial since it cannot adiabatically be deformed into a topologically trivial atomic insulator without closing the energy gap. We use nodal lines carrying a nontrivial $Z_{2}$ monopole charge in three dimensions to illustrate the physics. Notably, because the wrapping surfaces for an extended band degeneracy are diverse, we find that this generalization can bring topological insulators with unconventional pattern of boundary states.

CD68+ macrophages as crucial components of the foreign body reaction demonstrate an unconventional pattern of functional markers quantified by analysis with double fluorescence staining.

Implants like meshes for the reinforcement of tissues implement the formation of a persistent inflammation with an ambient fibrotic reaction. In the inflammatory infiltrate several distinct cell types have been identified, but CD68+ macrophages are supposed to be most important. To investigate the collaboration among the various cell types within the infiltrate we performed at explanted meshes from humans double fluorescence staining with CD68 as a constant marker and a variety of other antibodies as the second marker. The list of second markers includes lymphocytes (CD3, CD4, CD8, CD16, CD56, FoxP3, and CD11b) stem cells (CD34), leucocytes (CD45, CD15), macrophages (CD86, CD105, CD163, and CD206); deposition of EC matrix (collagen-I, collagen-III, MMP2, and MMP8); Ki67 as a marker for proliferation; and the tyrosine-protein kinase receptor AXL. The present study demonstrates within the inflammatory infiltrate the abundant capability of CD68+ cells to co-express a huge variety of other markers, including those of lymphocytes, varying between 5 and 83% of investigated cells. The observation of co-staining was not restricted to a specific polymer but was seen with polypropylene fibers as well as with fibers made of polyvinylidene fluoride, although with differences in co-expression rates. The persisting variability of these cells without the functional reduction toward differentiated mature cell types may favor the lack of healing at the interface of meshes.

Leptogenesis after superconformal subcritical hybrid inflation

We consider an extended version of superconformal subcritical hybrid inflation model by introducing three right-handed neutrinos that have the Majorana mass terms. In the model one of the right-handed sneutrinos plays a role of the inflaton field, and it decays to reheat the universe after inflation. The vacuum expectation value for the waterfall field gives an unconventional pattern of the light neutrino mass matrix, and the neutrino Yukawa couplings that determine the reheating temperature are not constrained by the neutrino oscillation data. Consequently thermal leptogenesis or sneutrino leptogenesis is realized.

Technical Note: Silica stable isotopes and silicification in a carnivorous sponge <i>Asbestopluma</i> sp.

Abstract. The stable isotope composition of benthic sponge spicule silica is a potential source of palaeoceanographic information about past deep seawater chemistry. The silicon isotope composition of spicules has been shown to relate to the silicic acid concentration of ambient water, although existing calibrations do exhibit a degree of scatter in the relationship. Less is known about how the oxygen isotope composition of sponge spicule silica relates to environmental conditions during growth. Here, we investigate the vital effects on silica, silicon and oxygen isotope composition in a carnivorous sponge, Asbestopluma sp., from the Southern Ocean. We find significant variations in silicon and oxygen isotopic composition within the specimen that are related to unusual spicule silicification. The largest variation in both isotope systems was associated with the differential distribution of an unconventional, hypersilicified spicule type (desma) along the sponge body. The absence an internal canal in the desmas suggests an unconventional silicification pattern leading to an unusually heavy isotope signature. Additional internal variability derives from a systematic offset between the peripheral skeleton of the body having systematically a higher isotopic composition than the internal skeleton. A simplified silicon isotope fractionation model, in which desmas were excluded, suggests that the lack of a system for seawater pumping in carnivorous sponges favours a low replenishment of dissolved silicon within the internal tissues, causing kinetic fractionation during silicification that impacts the isotope signature of the internal skeleton. Analysis of multiple spicules should be carried out to "average out" any artefacts in order to produce more robust downcore measurements.

Phosphoantigens and butyrophilin 3A1 induce similar intracellular activation signaling in human TCRVγ9+ γδ T lymphocytes

Human γδ cells expressing TCRVγ9 are T lymphocytes with great potential for cancer immunotherapy and unconventional pattern of antigen specificity. These HLA-unrestricted lymphocytes are specifically reactive to non-peptide metabolites (phosphoantigens) and to the butyrophilin 3A (BTN3A/CD277) protein. Whether recognition of such highly different structures trigger the same activation signaling pathway remains unclear, however. Here we combined fluorescent cell barcoding and phosphoflow analysis of TCRVγ9+ T lymphocytes to compare simultaneously the level of several signaling phosphoproteins after activation by phosphoantigen (BrHPP) or by anti-BTN3A (monoclonal antibody 20.1). This approach shows that the same pathways involving ZAP70, PLCγ2, Akt, NFκB p65, MAPK p38 and Erk1, were induced by either of these stimuli. These data strongly suggest the TCRVγ9+ T lymphocytes detect phosphoantigens and butyrophilin A3 by the same recognition process.

Management of skeletal deep overbite in an adult class II division 1 malocclusion by unconventional extraction pattern

The ideal treatment protocol for an adult patient with skeletal class II division 1 malocclusion and deep bite has beyond doubt been accepted as combined surgical and orthodontic management including upper and lower bicuspid extractions. Here, a case report has been presented where a similar problem has been managed with conventional orthodontics alone and selecting an unconventional extraction pattern taking into consideration certain key factors that aid in long-term retention. Instead of extraction approach of upper and lower bicuspids, extraction of two upper bicuspids and single incisor extraction was done in the mandibular arch.

Ammonium‐Based Cellulose Solvents Suitable for Homogeneous Etherification

New ammonium-based cellulose solvents with triethylmethylammonium- and tributylmethylammonium cations and carboxylate anions were synthesized and investigated as potential solvents for cellulose. Triethylmethylammonium formate was found to dissolve cellulose. Small amounts of formic acid may be used to adjust the melting point of the organic salt and can increase the dissolution velocity of cellulose. Carboxymethylation as a common etherification reaction was investigated in the new ammonium-based system. The watersoluble carboxymethyl cellulose obtained, had a degree of substitution as high as 1.55. An unconventional pattern of substitution was accessible.

Monophonic sound source separation with an unsupervised network of spiking neurones

We incorporate auditory-based features into an unconventional pattern classification system, consisting of a network of spiking neurones with dynamical and multiplicative synapses. Although the network does not need any training and is autonomous, the analysis is dynamic and capable of extracting multiple features and maps. The neural network allows computing a binary mask that acts as a dynamic switch on a speech vocoder made of an FIR gammatone analysis/synthesis bank of 256 filters. We report experiments on separation of speech from various intruding sounds (siren, telephone bell, speech, etc.) and compare our approach to other techniques by using the log spectral distortion (LSD) metric.

Electrical characteristics of Schottky diodes based on semi-insulating CdTe single crystals

Electrical properties of Schottky diodes fabricated by vacuum evaporation of Al on the surface of semi-insulating p-like CdTe single crystals have been investigated. The current-voltage characteristics (CVCs) of the diodes have an unconventional pattern which is manifested in the absence of rectification at both low forward bias voltages (<5V) and reverse bias in a wide range of voltages. The linear behavior of CVC is shown to be caused by a very high resistance of the CdTe substrate. In order to exclude an influence of the substrate and obtain the real CVC of the Al∕CdTe contacts, the samples were illuminated with low absorption light. A sharp increase in the forward current at higher voltages (>5V) is associated with the injection of minority carriers into the bulk of the crystals.

Public Mode Access And Waiting Time Variability In Maiduguri Metropolis

This work examines public mode access and waiting time variations in Maiduguri Metropolitan Area. Data for the study were sought through a comprehensive field survey using a travel diary questionnaire. A total of 623 households were surveyed in 342 dwelling units. The results indicate that variations in modal access and waiting time occur as a result of the unconventional operation pattern of the public transport systems. Another finding reveals that difference in land use activities in the city does not cause any significant variations in time. The implications of the work for policy considerations are outlined KEY WORDS: Mode, Access, Variation, Time, Waiting, Split Global Journal of Social Sciences Vol.3(1&2) 2004: 53-59

Pride, Humility, and the Petrarchan Happy Ending

Pride and humility are among the paired opposites so important to Renaissance Petrarchism. They sometimes figure in an assessment of the moral state of the male lover, but their most common usage is in connection with the female beloved, and often not in a high-minded way: the woman’s resistance to her would-be seducer’s suit is frequently attacked as a sin of pride. Spenser’s Amoretti is particularly full of discussions of the woman’s pride, but as part of an unconventional pattern: from the start that pride is both attacked and praised. This alternation is part of the dynamics of courtship as it is dramatized in the sequence, and also closely linked to the lover’s early (and accurate) confidence that his suit will be successful. Understanding the pattern here can help allay the confusion caused by the superscription to sonnet 58, and also lead to a fresh appreciation of the conceits of sonnets 45 and 75.

Unconventional pattern of reservoir facies distribution in epeiric successions: Lessons from an outcrop analog (Lower Keuper, Germany)

This article presents (1) a process-oriented description of an outcrop analog for epeiric successions; (2) a discussion of fundamental characteristics of epeiric basin fills; and (3) a generic depositional model, which may be used for improved reservoir prediction in epeiric settings. The case study focuses on the upper Ladinian, mixed siliciclastic-carbonate Lower Keuper Formation. It is composed of storm-generated, tide-generated, and bioturbated facies. Paleogeographically the succession shows an unusual lateral energy zonation comprising a seaward low-energy zone close to wave base; an intermediate, reservoir-prone, high-energy zone within wave base; and a landward low-energy zone above wave base. Stratigraphically the Lower Keuper Formation is subdivided into meter-scale transgressive-regressive cycles, correlatable over distances of more than 500 km. Cycle boundaries are interpreted to be isochronous. Within the resulting chronostratigraphic framework, facies distributions have been mapped out in three dimensions, revealing that reservoir-prone facies are most extensive in shoreline-detached positions. Reservoir bodies are thin, have sheetlike geometries but extend for several tens of kilometers, and are stacked in an aggradational facies architecture. Additionally, the reservoir-prone facies is thicker developed in zones of stronger subsidence, a few kilometers wide, linked to underlying basement blocks. Resulting unconventional reservoir prediction strategies for similar shallow-marine epeiric settings should target shoreline-detached high-energy facies belts that are preferentially developed within zones of stronger subsidence, controlled by basement tectonics.

Attentional limitations in processing sequentially presented vibrotactile targets.

In seven experiments, participants experienced rapid, serially presented streams of vibrations and responded to specific targets in the streams. In visual (and sometimes auditory) streams presented in this manner, it is typical to find a deficit in reporting the second of two targets when both must be reported and the second appears within a short temporal interval of the first, but not when identical displays are presented but only the second target must be reported (e.g., the attentional blink, or AB). This conventional AB pattern was found in the last experiment, in which judgments were about target location. However in the first six experiments reported here, in which judgments were about frequency, intensity, duration, or location of targets, accuracy was dependent on target separation regardless of whether or not the first target was reported. This unconventional pattern could represent an AB if the first target was attended even when it was not reported. The evidence for this claim and an alternative possibility that location judgments are especially sensitive to attention manipulations are discussed.

Quark and lepton masses in extended technicolor

We discuss the problem of obtaining a realistic spectrum of quark and lepton masses in extended technicolor (ETC), without inducing excessive flavour-changing neutral currents (FCNCs) and without leading to excessive deviations in the p-parameter. We concentrate on a conventional ETC model (i.e. without the assumption of a fixed point, and which does not involve the unnatural adjustment of any parameter), but which involves a rather unconventional pattern of symmetry breaking. This model, called chirally extended technicolor ( ξ ETC), which was recently proposed by one of us, is studied in full detail using Schwinger-Dyson equations in dressed ladder approximation, which are solved numerically. Our results show that this model provides a realistic description of quark and lepton masses without inducing excessive FCNCs and with δϱ ≈ 1.0–1.7% for a top quark mass in the range m t ≈ 100–125 GeV.

A systems approach to custom VLSI for a digital color imaging system

An analysis of system requirements is presented that guides the design of a chip set that provides all the required functionality and control for single-sensor color imaging systems. The first device is a color filter array (CFA) processor that processes the single stream of sparse color information from an unconventional CFA pattern and produces a full-resolution color image in real time. The second chip is a red, green, and glue (RGB) processor that improves the image quality of the reconstructed RGB data by performing black-level adjustment, color matrixing, gamma correction, and edge enhancement, again in real time. The third device is a timing controller with an architecture specifically suited to imaging systems. The chips are algorithm specific, and the algorithms, architectures, and design methodology are detailed. The chip set is readily applicable to slide and negative film-to-video converters, electronic still cameras, and component or composite video cameras. It is capable of operation with NTSC, CCIR 601, and PAL/SECAM video standards. >
