A Generative Model Method for Unsupervised Multispectral Image Fusion in\n Remote Sensing (2021)

This paper presents a generative model method for multispectral image fusion\nin remote sensing which is trained without supervision. This method eases the\nsupervision of learning and it also considers a multi-objective loss function\nto achieve image fusion. The loss function incorporates both spectral and\nspatial distortions. Two discriminators are designed to minimize the spectral\nand spatial distortions of the generative output. Extensive experimentations\nare conducted using three public domain datasets. The comparison results across\nfour reduced-resolution and three full-resolution objective metrics show the\nsuperiority of the developed method over several recently developed methods.\n
Blow-Out Stability of Gaseous Jet Diffusion Flames: Part III - Effect of Burner Orientation to Wind Direction (1982)

Abstract The orientation of the burner to the wind direction has been found to have a marked effect on the ability of the flame to resist being blown out by the wind. By using an effective wind speed (V+Ueff) instead of the actual wind speed V, it is shown thai for a given gas the data for different burner inclinations can be collapsed on to a single stability curve, which is the same as that for the case where wind direction is normal to the burner axis.
Stochasticity of particle orbits in a collective particle accelerator (1986)

A detailed investigation of the behavior of particle orbits in the simultaneous presence of three large amplitude waves such as those encountered in the collective particle accelerator experiment at the Naval Research Laboratory is undertaken. Stochasticity arising out of the resonance overlap of the waves can influence the particle dynamics significantly and thereby affect the outcome of the experimental results. Choice of initial phase and energy for successful operation is identified and discussed.
Surgical Lip Remodeling Following Permanent Filler Injection: A Scoping Review (2021)

Over the years, several techniques have been introduced to obtain permanent lip enhancement, such as the use of silicone lip implants or the off-label use of permanent fillers. Although some reports indicate that permanent lip filler is safe, many others describe early- and late-onset complications. The main issue with permanent lip fillers is the lack of a standard technique to correct undesirable results. The aim of this scoping review was to list and evaluate the surgical pathways described in literature to correct lip deformity resulted from the injection of permanent fillers. The methods and the inclusion criteria of this work were specified in advance and documented in a protocol, according to the PRISMA 2009 checklist. The research was carried out on electronic databases PubMed, Cochrane Library, and Scopus databases identifying articles from March 1991 to December 2020 and conducted up to December 23rd, 2020. Articles language was limited to English. The selection process identified 3 retrospective studies eligible for inclusion. 73 patients and a total of 111 lips (72 upper and 39 lower) were considered. Two early complications were identified, 1 suture dehiscence and 1 total lip mucosa necrosis. Surgical lip remodeling following permanent filler injection seems to be an effective approach although the surgical pathway needs to be customized per each patient. Complication rate seems to be coherent to lip surgery performed with reconstructive purposes. To confirm these data case-control studies with much wider cohorts are needed to reach statistical significance.
Pigmented Fundus Lesions in a Preterm Infant With Familial Adenomatous Polyposis (1993)

Congenital hypertrophy of the retinal pigment epithelium (CHRPE) refers to a flat, well-demarcated ocular fundus lesion with clinically normal overlying retina. Presumed to be congenital, CHRPE has been described in children as young as age 3 months.<sup>1</sup>Multiple pigmented ocular fundus lesions similar to those in CHRPE are often associated with familial adenomatous polyposis (FAP), with or without extracolonic manifestations, including osteomas, epidermal cysts, desmoid tumors, or malignant tumors of the liver, thyroid, or brain (Gardner's syndrome).<sup>2</sup>Familial adenomatous polyposis is an autosomal-dominant inherited disorder in which patients invariably progress to develop adenocarcinoma of the colon. Prophylactic colectomy is routinely performed. The presence of multiple pigmented fundus lesions is a highly specific clinical genetic marker in individuals at risk for FAP, with or without extracolonic disease.<sup>1</sup> We report a case of multiple pigmented fundus lesions observed 32 weeks after conception in a premature infant with previously unknown
Novel transmit protection scheme for ultrasound systems (2007)

The problem of protecting or isolating extremely sensitive receive circuitry from high-voltage transmit circuitry is commonly addressed through the use of diode bridges, transformers, or high-voltage switches, which prove to be prohibitively expensive, bulky, and power consuming for use in portable, low-cost, battery-powered systems. These approaches also compound the interconnect difficulties associated with two-dimensional (2-D) transducer arrays. In this paper we present a novel transmit protection scheme that allows compact MOSFET shunting devices to be brought on-chip within each receive channel implemented in a standard CMOS integrated circuit process. During transmit, the high voltage transmit pulse is driven onto the common connection of the transducer array and the on-chip MOSFET devices shunt the current to ground. During receive, these devices are turned off, the common connection of the transducer array is shunted to ground, and the received echo can be detected as usual. The transmit protection scheme was experimentally shown to shunt a 16 mA peak current resulting from the equivalent of a 100-V, 25-ns-risetime transmit pulse through a 4 pF transducer element. The scheme was also incorporated into a prototype 1024-channel, low-cost, ultrasound system successfully used to form pulse echo images.
Innovative Materials, Devices, and CMOS Technologies for Low-Power Mobile Multimedia (2008)

The paradigm and the usage of CMOS are changing, and so are the requirements at all levels, from transistor to an entire CMOS system. The traditional drivers, such as speed and density of integration, are subject to other prerogatives related to variability, manufacturability, power consumption/dissipation (mobile products!), mix of varied digital and analog/RF functions (system-on-chip integration), etc. Controllability of variations and static leakage will add to, and in certain products prevail, over speed and density. Implications at all levels are multiple and are more diverse than just speed and smallness. The goal of the authors has been to see the problem globally from the product level and to place its components in their true proportions. Therefore, we will start with drawing the product-level picture and placing it in a historical perspective. Next, we will review the state of the art, the requirements, and solutions at the level of materials, transistor, and technology. Detailed analysis and potential solutions for prolonging CMOS as the leading information technology are presented in this paper.
Conformational studies on the tRNA-guanine transglycosylase substrate: queuine (1986)

The heterocyclic base 7-(3,4-trans-4, 5-cis-dihydroxy-1-cyclopenten-3-ylaminomethyl)-7-deazaguanine, queuine or Q base has been found in the tissues, and fluids of many different organisms, as well as in their tRNAs. Queuine is found in that first, or wobble position of the anticodons of aspartic acid, asparagine, histidine and tyrosine tRNAs. Queuine, or the Q base precursor in E. coli, are inserted posttranscriptionally into the tRNA via a unique enzymatic reaction. Therefore, the physical structure of the enzyme substrate, native queuine, is of exceeding interest. Here the authors report the structure of the base isolated recently from natural sources and determined by /sup 1/H and /sup 13/C one and two dimensional (COSY, NOESY) NMR techniques. The solution structure was slightly different from that of the x-ray crystallographic structure of the nucleoside. New proton signal assignments for protons H-1 and H-2 from the side chain cyclopentenediol ring together with carbon (/sup 13/C) chemical shift assignments are presented. The structural conformation of the base has implications for the enzymatic reaction with precursor tRNA.
Lithospheric flexure and gravity spreading of Olympus Mons volcano, Mars (2016)

Abstract The structural architecture of large volcanoes is governed substantially by gravity‐driven deformation that is manifest as distinct processes such as basement flexure or volcanic spreading. Temporal effects and the mutual interplay of these processes have been investigated only to a limited extent, and so we present novel numerical models of the time‐dependent deformation associated with them. The models simulate the combined effects of lithospheric flexure and volcanic spreading during growth increments of an elastoplastic volcanic cone. Different spreading scenarios are considered by a variable coupling decoupling behavior at the interface between volcano and basement. We apply our models to Olympus Mons on Mars, which is characterized by upper to middle flank terraces on the shield, is encircled by a basal scarp that has an average slope of 30° and is surrounded by distant deposits that resemble large‐scale slumping features on Earth. Our results are consistent with the interpretation that terraces on Olympus Mons' flanks form by thrust faulting that results from lithospheric flexure. The presence and expression of terraces depend on the coupling of volcano and basement, on the time of volcano growth relative to mantle relaxation, and on the cohesion of the edifice. The encircling scarp may be related to a very low friction detachment at the edifice base, which leads to a normal fault regime on the lowermost flanks. With time and volcano growth, predicted stress and faulting regimes migrate only slightly, indicating that the structural architecture of volcanoes is largely set in the very early stages of formation.
Compound dislocation models (CDMs) for volcano deformation analyses (2016)

Volcanic crises are often preceded and accompanied by volcano deformation caused by magmatic and hydrothermal processes. Fast and efficient model identification and parameter estimation techniques for various sources of deformation are crucial for process understanding, volcano hazard assessment and early warning purposes. As a simple model that can be a basis for rapid inversion techniques, we present a compound dislocation model (CDM) that is composed of three mutually orthogonal rectangular dislocations (RDs). We present new RD solutions, which are free of artefact singularities and that also possess full rotational degrees of freedom. The CDM can represent both planar intrusions in the near field and volumetric sources of inflation and deflation in the far field. Therefore, this source model can be applied to shallow dikes and sills, as well as to deep planar and equidimensional sources of any geometry, including oblate, prolate and other triaxial ellipsoidal shapes. In either case the sources may possess any arbitrary orientation in space. After systematically evaluating the CDM, we apply it to the co-eruptive displacements of the 2015 Calbuco eruption observed by the Sentinel-1A satellite in both ascending and descending orbits. The results show that the deformation source is a deflating vertical lens-shaped source at an approximate depth of 8 km centred beneath Calbuco volcano. The parameters of the optimal source model clearly show that it is signicantly different from an isotropic point source or a single dislocation model. The Calbuco example reflects the convenience of using the CDM for a rapid inter-&#13;\npretation of deformation data.
Efficient Demultiplexing of Network Packets by Automatic Parsing (1995)

Packet filters are a mechanism for efficiently demultiplexing network packets to application endpoints. There is currently no general, formal specification method for packet filters that allows for easy or efficient composition of specifications. In this paper we present an automatic approach that achieves all of these goals. We approach packet filter specification as a language recognition problem: each filter is represented by a context-free grammar, whose language is the set of packets the filter should accept. Thus, packet filters can be formulated through a general, well defined specification; further, the grammar-based approach simplifies filter composition, which is essential where scalability is important. However packet filters based on standard LR parsing techniques suffer from poor performance they touch every portion of the input, they check input bit by bit, they occupy large amount of space. We present new optimizations to LR parsing that enable our automatic approach to overcome the above problems and achieve performance rivalling hand-crafted approaches. We present results that compare our approach to the BSD packet filter for TCP connections; our approach shows significant improvements when there are multiple filters installed: for 50 TCP connections our approach is 6 times faster.
Clustering earthquake signals and background noises in continuous seismic data with unsupervised deep learning (2020)

The continuously growing amount of seismic data collected worldwide is outpacing our abilities for analysis, since to date, such datasets have been analyzed in a human-expert-intensive, supervised fashion. Moreover, analyses that are conducted can be strongly biased by the standard models employed by seismologists. In response to both of these challenges, we develop a new unsupervised machine learning framework for detecting and clustering seismic signals in continuous seismic records. Our approach combines a deep scattering network and a Gaussian mixture model to cluster seismic signal segments and detect novel structures. To illustrate the power of the framework, we analyze seismic data acquired during the June 2017 Nuugaatsiaq, Greenland landslide. We demonstrate the blind detection and recovery of the repeating precursory seismicity that was recorded before the main landslide rupture, which suggests that our approach could lead to more informative forecasting of the seismic activity in seismogenic areas.
Quantum feedback: controlling entangled states in cavity QED and optical quantum computing (2004)

Quantum optical feedback is emerging as a powerful tool in quantum physics and quantum information. I present new results from the first (2002) “deep quantum” feedback experiment, and a new theoretical analysis showing how entanglement is essential in it. I also present applications of quantum feedback to optical quantum computing.
Synthesis and self‐assembly of a chiral alternating sexithiophene–undeca(ethyleneoxy) block copolymer (2003)

Abstract An oligothiophene/chiral oligo(ethyleneoxy) block copolymer (PolyT6) has been synthesized in which a sexithiophene block alternates with a well‐defined chiral undeca(ethyleneoxy) block. The polymer shows good solubility in chloroform, and ultraviolet–visible studies in this solvent reveal a spectrum similar to that of the chirally substituted monomeric sexithiophene (T6) analogue. The aggregation of PolyT6 occurs in dioxane; however, no helicity is present in this aggregate, in contrast to aggregated T6. This behavior illustrates that although the processability and mechanical robustness of block copolymers may be superior to those of analogous oligomers, the degree of self‐assembled order found in oligomer‐based systems may be lost in the polymers. © 2003 Wiley Periodicals, Inc.

Tetraazaperopyrenes: A New Class of Multifunctional Chromophores (2007)

Tetraazaperopyrene and a range of derivatives have been synthesised and their photophysical and redox-chemical properties studied. The parent compound, 1,3,8,10-tetraazaperopyrene (1), was prepared by treating 4,9-diamino-3,10-perylenequinone diimine with triethyl orthoformate, whereas the 2,9-disubstituted derivatives of 1 were obtained after treatment with the corresponding carboxylic acid chloride or anhydride (2 mol equiv). The 1,3,8,10-tetraazaperopyrene core structure was established by X-ray diffraction of 2,9-bis(2-bromophenyl)-1,3,8,10-tetraazaperopyrene (6). The UV-visible absorption spectra of the compounds have a characteristic visible pi(*)<--pi absorption band at 440 nm (log epsilon(max)=4.80) with a strong vibrational progression (Delta nu approximately 1450 cm(-1)). Diprotonation of the nitrogen atoms induces a bathochromic shift of this band from 430-440 to 470-480 nm and all four nitrogen atoms are protonated when pure H(2)SO(4) is used as the solvent. The first and second as well as the third and fourth protonations occur concomitantly, which implies that they have very similar pK(a) values and, consequently, similar proton affinities. A theoretical study of the proton affinities in the gas phase and in solution attributes this behaviour to the effects of polar solvents, which dampen the charge of a protonated site at the other end of the molecule and thus effectively decouple the two opposite pyrimidine units in the polycondensed aromatic compound. The photophysical data were modelled in a time-dependent DFT study of 1, 1H(2)(2+) and 1H(4)(4+) in both the gas phase and in a polar solvent. All the dyes show weak fluorescence in organic solvents, however, their protonated conjugate acids show dramatically increased fluorescence intensity. All of the dyes undergo two electrochemically reversible one-electron reductions with cyclovoltammetric half-wave potentials at E(red1) approximately -0.9 V and E(red2) approximately -1.3 V (vs. SCE), which are associated with characteristic spectral changes.

Individual Differences in Masturbation and Erotica Consumption Predicting Levels of Sexual Concordance (2018)

Concordance is not the only aspect of sexuality where significant gender differences are observable: men masturbate significantly more than women (Oliver &amp; Hyde, 1993; Petersen &amp; Hyde, 2011). There are also large gender differences in pornography consumption and consumption patterns (Hald, 2006). The study of concordance is important as it could assist in the further development of models of sexual response, and potentially reveal the role of gender differences in those models. Evidence suggests that the cognitive system one uses to process stimuli can affect one's subjective sexual arousal (Dove &amp; Wiederman, 2000). Greater erotica consumption habits could lead to a better familiarity with the erotic stimuli used during the testing protocol, and this decreased novelty could produce more accurate responses for subjective sexual arousal. Using a "bottom-up" cognitive model in which people use physical sensations to infer emotional states, it is likely that increased sexual experience will lead to higher levels of concordance. Opposite-sex attracted participants (24 men and 25 women) will view a series of audiovisual stimuli depicting heterosexual sexual acts and neutral subjects. Participants will answer a series of questionnaires about their sexual history and attitudes, and will answer questions on their level of sexual arousal before and after each stimulus. Participants will continuously report their levels of subjective sexual arousal while simultaneously their genital responses, heart rate and skin conductance will be recorded. It is important to further our understanding of how much impact a participant's previous exposure to erotica, and masturbation behaviours to that erotica, have on their concordance rates; given the increasing pervasiveness and accessibility of erotica, this may prove extremely relevant to future nvestigations
Purification of an antifungal PR‐5 protein from flower buds of Brassica campestris and cloning of its gene (1997)

An antifungal pathogenesis‐related (PR) group 5 protein with a molecular mass of 27 kDa (BFTP) was purified from flower buds of Brassica campestris . BFTP exhibits antifungal activity against Neurospora crassa , causing rapid release of cytoplasmic material at the hyphal tips of the fungus. BFTP immuno‐cross‐reacts with antiserum raised against the tobacco osmotin‐like PR‐5 protein. Using a PCR product generated with the help of two degenerate PCR primers for (1) the N‐terminal amino acid sequence of the protein and (2) the conserved peptide domain that appears in all PR‐5 proteins, we were able to isolate from a flower‐bud cDNA library a cDNA (933 bp) that encodes this protein ( pBFTP ). The deduced amino acid sequence shows high similarity to PWIR2 from wheat (43%) and thaumatin II from Thaumatococcus daniellii Benth (40%). It contains the 16 cysteine residues that are conserved in all PR‐5 proteins at their invariant positions. The cDNA predicts the synthesis of a preprotein which is subsequently processed into the mature protein by removal of an N‐terminal signal peptide. The mRNA is predominantly expressed in flower buds, with a moderate level of transcripts detected in stems. Very low levels of the mRNA are present in root and leaf tissue. The gene is a member of a small multigene family in the genome of B. campestris .
Thermophysical property measurements in electromagnetic levitators (1990)

Proper measurements of thermophysical properties of hot levitated liquid drops require the following: accurate temperature measurement (brightness measurement, emissivity measurement); precise drop shape measurements with submillisecond time resolution (density determination, rotational and vibrational shape information); precise control of drop shape (high symmetry variable gap levitators); accurate energy transfer measurements (direct measurements of energy transfer rates for defined gas flows over samples with quantitative measurements of energy transfer rates for defined flows over samples with known shapes); and precise measurements of repetitive sample motions (rapid repetitive shape measurements, frequency measurements with reflected laser light, measurements in the levitator and as a freely falling drop). Recent advances in coil design and control of sample rotation in an electromagnetic levitator are discussed with respect to the above requirements.
Bilateral asymmetrical multiple renal arteries associated with the left testicular artery (2014)

We found 3 right and 2 left renal arteries with asymmetrical origins in a 61-year-old Korean male cadaver, whose cause of death was 'laryngeal carcinoma'. According to a previous classification, the first and second right renal arteries correspond to the early division and other renal arteries - to the extra renal arteries, except the first left renal artery as a typical renal artery. The third right renal artery ran anterior to the inferior vena cava to the inferior pole of the kidney. The first and second left renal arteries were associated with the inferior suprarenal artery and the testicular artery, respectively. The bilateral asymmetry in the number of renal arteries can be explained by the embryological development, degeneration and persistence of the renal artery in the process of ascending of kidneys.
