Lightening Network for Low-Light Image Enhancement (2020)

Low-light image enhancement is a challenging task that has attracted considerable attention. Pictures taken in low-light conditions often have bad visual quality. To address the problem, we regard the low-light enhancement as a residual learning problem that is to estimate the residual between low- and normal-light images. In this paper, we propose a novel Deep Lightening Network (DLN) that benefits from the recent development of Convolutional Neural Networks (CNNs). The proposed DLN consists of several Lightening Back-Projection (LBP) blocks. The LBPs perform lightening and darkening processes iteratively to learn the residual for normal-light estimations. To effectively utilize the local and global features, we also propose a Feature Aggregation (FA) block that adaptively fuses the results of different LBPs. We evaluate the proposed method on different datasets. Numerical results show that our proposed DLN approach outperforms other methods under both objective and subjective metrics.
Association Between Muscular Strength and Cognition in People With Major Depression or Bipolar Disorder and Healthy Controls (2018)

Grip strength may provide a useful indicator of cognitive impairment in people with major depression and bipolar disorder. Future research should investigate causality, assess the functional implications of handgrip strength in psychiatric populations, and examine how interventions to improve muscular fitness affect neurocognitive status and socio-occupational functioning.
Friction of polymer films. I. Lubrication (1964)

The behavior of several long chain fatty lubricants in thin films of vinylidene chloride-acrylonitrile copolymer and the nature of the lubricated polymer surfaces were studied by means of frictional measurements, critical surface tension of wetting, and light microscopy. The surfaces of the bulk lubricants were also characterized by wetting studies. The critical surface tension of wetting parameter was found to be both a means of characterizing the configuration of the lubricant layer and a measure of the extent to which the polymer surface was covered by the lubricant. There was no evidence of orientation of the lubricant layer on the polymer surface and no evidence of plasticization of the polymer by the lubricant. All lubricants studied appeared in the bulk state at the polymer surface in quantities related to the chain length and chemical constitution of the lubricant. Correlations were observed between the coefficient of static friction of the polymer film and its critical surface tension of wetting. Solid fatty amides having chain lengths of eighteen carbon atoms or greater were found to be effective lubricants for the polymer studied. The lubricating action of these fatty materials was explained in terms of their low surface energies and high structural strengths when in the bulk crystalline state.
Concept Mapping and Guided Inquiry as Effective Techniques for Teaching Difficult Concepts in Chemistry: Effect on Students’ Academic Achievement (2013)

The persistent poor performance in chemistry in Nigerian school system, especially at the secondary level, has been quite a serious problem. The major purpose of this study determined how the adoption of concept mapping and guided inquiry as instructional strategies can enhance more meaningful understanding of difficult concepts in chemistry and increase students ’ academic achievement. To guide the study a research question and hypothesis were asked, formulated and tested at; 0.05 level of significance. The design was a non-randomized pre-test, post-test, control group quasi-experimental design using intact classes in 251 Senior Secondary three (SS III) Chemistry students in the three senatorial districts of Taraba state which were randomly assigned, experimental and group through balloting using the replacement and withdrawal technique. Face and content validity of instruments were ascertained using the Pearson’s Moment Correlation to obtain a reliability coefficient of 0.79. Analysis of Covariance (ANCOVA) was tested at; 0.05 level of significance, means and standard deviation were used to analyze the data. Also, Multiple Classification Analysis (MCA) using the Sheffe test was computed to indicate the direction of the difference. The result of the analysis showed a significant difference between the performance of students exposed to the two experimental groups (concept mapping and guided-inquiry methods) and the control group (expository method), the result of the Sheffe test was in the
A 5.5ym CMOS image sensor cell utilizing a buried reset channel (1997)

A CMOS image sensor cell suitable for miniaturization is proposed. The number of gate polysilicons in a cell was reduced from 3 to 1 by utilizing a stacked capacitor and a buried reset channel. A cell of 5.5x5.5ym2 applicable to 1/4 inch VGA device was produced with 23% of photodiode area using 0.7pm design rule. Fabrication processes are compatible with stacked capacitor DRAM. Saturation signal amplitude of 1.OV and conversion gain of 9uVlelectron were obtained with 5V power
Case report: apixaban‐induced thrombocytopenia (2017)

Apixaban is a relatively new drug, and its safety profile is still being established. Thrombocytopenia is an uncommon, but life-threatening side effect with no previous published case repots. Clinicians must be aware of this and exercise caution particularly as some studies hint that it may be used in the management of HIT.

Progressive tetrahedralizations (1998)

The paper describes some fundamental issues for robust implementations of progressively refined tetrahedralizations generated through sequences of edge collapses. We address the definition of appropriate cost functions and explain on various tests which are necessary to preserve the consistency of the mesh when collapsing edges. Although considered a special case of progressive simplicial complexes (J. Popovic and H. Hoppe, 1997), the results of our method are of high practical importance and can be used in many different applications, such as finite element meshing, scattered data interpolation, or rendering of unstructured volume data.
Islet Amyloid Develops Diffusely Throughout the Pancreas Before Becoming Severe and Replacing Endocrine Cells (2001)

Islet amyloid occurs in &gt;90% of type 2 diabetic patients and may play a role in the pathogenesis of this disease. To determine whether islet amyloid occurs diffusely throughout the pancreas, whether it affects islets equally, and whether it decreases islet endocrine cells, we characterized islet amyloidosis by computerized fluorescence microscopy in transgenic mice that develop typical islet amyloid. These mice produce the unique amyloidogenic component of human islet amyloid, human islet amyloid polypeptide (hIAPP). The prevalence of amyloid (number of islets containing amyloid/total number of islets × 100) and the severity of amyloid (Σamyloid area/Σislet area × 100) were found to be uniform throughout the pancreas. Furthermore, a high prevalence of amyloid was observed in islets when the severity of amyloid was only 1.5% of the islet area, suggesting a diffuse distribution of amyloid from the very early stages of islet amyloidosis. In 12 hIAPP transgenic mice with an amyloid severity of 9.6 ± 3.4%, the proportion of islets composed of β- and δ-cells was reduced in the transgenic mice compared with 6 nontransgenic mice that do not develop amyloid (β-cells: 62.9 ± 3.1% vs. 75.5 ± 0.9%, P = 0.02; δ-cells: 2.8 ± 0.5% vs. 4.4 ± 0.4%, P = 0.05), whereas the proportion of islets composed of α-cells did not significantly differ between the two groups of mice. In the individual islets in these transgenic mice, amyloid severity was inversely correlated with β-cell, (r = −0.59, P &lt; 0.0001), α-cell (r = −0.32, P &lt; 0.0001), and δ-cell (r = −0.25, P &lt; 0.0001) areas. In conclusion, islet amyloidosis occurs uniformly throughout the pancreas, affecting all islets before becoming severe. A reduction in islet endocrine mass starts at this early stage of islet amyloid development and progresses as amyloid mass increases.
Connexin‐mimetic peptides dissociate electrotonic EDHF‐type signalling <i>via</i> myoendothelial and smooth muscle gap junctions in the rabbit iliac artery (2004)

Synthetic peptides corresponding to the Gap 26 and Gap 27 domains of the first and second extracellular loops of the major vascular connexins (Cx37, Cx40 and Cx43), designated as (43)Gap 26, (40)Gap 27, (37,40)Gap 26 and (37,43)Gap 27 according to Cx homology, were used to investigate the role of gap junctions in the spread of endothelial hyperpolarizations evoked by cyclopiazonic acid (CPA) through the wall of the rabbit iliac artery. Immunostaining and confocal microscopy demonstrated that gap junction plaques constructed from Cx37 and Cx40 were abundant in the endothelium, whereas Cx43 was the dominant Cx visualized in the media. None of the Cx-mimetic peptides affected endothelial hyperpolarizations evoked by CPA directly. When administered individually, (40)Gap 27, (37,40)Gap 26 and (37,43)Gap 27, but not (43)Gap 26, attenuated endothelium-dependent subintimal smooth muscle hyperpolarization. By contrast, only (43)Gap 26 and (37,43)Gap 27 reduced the spread of subintimal hyperpolarization through the media of the rabbit iliac artery. The site of action of the peptides therefore correlated closely with the expression of their target Cxs in detectable gap junction plaques. The findings provide further evidence that the EDHF phenomenon is electrotonic in nature, and highlight the contribution of myoendothelial and homocellular smooth muscle communication via gap junctions to arterial function.

Use of mutants to establish (+)-scytalone as an intermediate in melanin biosynthesis by <i>Verticillium dahliae</i> (1976)

Melanin biosynthesis in Verticillium dahliae Kleb, was studied with mutants deficient for normal black melanin or for production of microsclerotia. Seven genetically different mutants had apparent blocks in melanin biosynthesis. Four mutants (brm-1 to -4) produced brown microsclerotia and extruded pigments into media; three (alm-1 to -3) produced albino microsclerotia. Other mutants produced no microsclerotia (nms) or had greatly reduced numbers of microsclerotia (rms). Mutation alm-1 was due to a single recessive gene; the other melanin-deficient characters were recessive but their genetic bases were not determined. Cultures of the brown mutants brm-1 and -3 extruded and accumulated a metabolite that blackened the albino microslerotia of alm-1 to -3. The metabolite was identified as (+)-scytalone (3,4-dihydro-3,6,8-trihydroxy-1(2H)naphthalenone). Pigment formed by alm-1 microsclerotia from (+)-scytalone had chemical and physical properties identical with those of melanin in the wild-type fungus. (+)-Scytalone was produced and converted to melanin by microsclerotia but not by conidia or hyphae. Conversion of (+)-scytalone to melanin appeared to involve two or more enzymes and probably involved conversions to 1,3,8,-trihydroxynaphthalene and 1,8-dihydroxynaphthalene. Albino mutants of Thielaviopsis basicola, Drechslera sorokiniana, Pleospora infectoria (Alternaria), Ulocladium sp., and Curvularia sp. also converted scytalone to pigments indistinguishable from the melanins found in their respective wild types. Scytalone melanin may be common in fungi with dark brown or black pigments.
Automated homogeneous liposome immunoassay systems for anticonvulsant drugs. (1992)

We developed automated homogeneous immunoassays, based on immunolysis of liposomes, for measuring phenytoin, phenobarbital, and carbamazepine from serum. Liposome lysis was detected spectrophotometrically from entrapped glucose-6-phosphate dehydrogenase activity. The procedure was fully automated on a routine automated clinical analyzer. Within-run, between-run, dilution, and recovery tests showed good accuracies and reproducibilities. Bilirubin, hemoglobin, triglycerides, and Intrafat did not affect assay results. The results obtained by liposome immunoassays for phenytoin, phenobarbital, and carbamazepine correlated well with those obtained by enzyme-multiplied immunoassay (Syva EMIT) kits (r = 0.995, 0.986, and 0.988, respectively) and fluorescence polarization immunoassay (Abbott TDx) kits (r = 0.990, 0.991, and 0.975, respectively). The proposed method should be useful for monitoring anticonvulsant drug concentrations in blood.
THE EFFECT OF FERTILIZER NITROGEN AND FREQUENCY OF DEFOLIATION ON YIELD OF GRASSLAND HERBAGE (1965)

The effects of 4 levels of applied nitrogen, ranging from nil to a maximum of 417 lb N/ acre/annum, in all combinations with 3 frequencies of defoliation, ranging from 2 to a maximum of 10 cuts per annum, on herbage production from a perennial ryegrass/ timothy/meadow fescue/white clover sward were measured. These treatments were operative for 2J years, and in a subsequent year the residual effect of cutting frequency was tested. Dry‐matter yields of total herbage and of the clover fraction are quoted, together with N yields of total herbage. Yield response to N was higher than in some other experiments in the U. K. Cutting frequency had a very large effect and, in general, the longer the interval between cuts, the higher was the dry‐matter (though not the N) yield. There was a marked interaction between cutting frequency and level of N: at the high cutting frequency, dry‐matter yield increased linearly with increasing level of N; at the medium frequency, response tended to fall off at the highest level of N; at the low frequency, yield declined with increasing level of N beyond 139 lb N per acre per anum.
Two Retinotopic Visual Areas in Human Lateral Occipital Cortex (2006)

We describe two visual field maps, lateral occipital areas 1 (LO1) and 2 (LO2), in the human lateral occipital cortex between the dorsal part of visual area V3 and visual area V5/MT+. Each map contained a topographic representation of the contralateral visual hemifield. The eccentricity representations were shared with V1/V2/V3. The polar angle representation in LO1 extended from the lower vertical meridian (at the boundary with dorsal V3) through the horizontal to the upper vertical meridian (at the boundary with LO2). The polar angle representation in LO2 was the mirror-reversal of that in LO1. LO1 and LO2 overlapped with the posterior part of the object-selective lateral occipital complex and the kinetic occipital region (KO). The retinotopy and functional properties of LO1 and LO2 suggest that they correspond to two new human visual areas, which lack exact homologues in macaque visual cortex. The topography, stimulus selectivity, and anatomical location of LO1 and LO2 indicate that they integrate shape information from multiple visual submodalities in retinotopic coordinates.

ONE-STEP OFFSHORE OIL SKIM AND BURN SYSTEM FOR USE WITH VESSELS OF OPPORTUNITY (2014)

ABSTRACT Vessels of opportunity (VoOs), such as fish and shrimp boats, can be employed to aide offshore oil spill response operations. During the 2010 Macondo response, VoOs were utilized to collect surface slicks in booms, however, VoOs were not equipped to skim and recover the collected oil. Because of this, dedicated skimming vessels were directed to VoOs to skim and store the oil. This process is not very efficient as VoOs can often remain idle for long periods while waiting for dedicated skimming vessels to arrive and process the collected oil. The research presented here aims to improve the effectiveness of VoO operations through development of a one-step skim and burn system. The system under development is based on the combined use of oleophilic skimmers, which can recover oil and water mixtures capable of direct combustion. Our concept would be for a VoO to collect oil in the booms, skim the oil from the booms using an oleophilic skimmer, and then pump the recovered mixture to a floating combustion system located downwind without the need for large volumes of interim storage or decanting. The three primary objectives for system development and design are to 1) improve combustion efficiency, thereby reducing environmental impacts; 2) achieve burn rates comparable to oil recovery rates of the oleophilic skimmers utilized, enabling more efficient oil spill response operations and less down-time; and 3) design a relatively simple and robust system that will enable safe burn operations. Experimental results from initial testing of small and medium scale burning systems will be presented. Direct combustion of skimmed oil was successfully demonstrated. Further, burns were completed with decreased smoke generation and burn residue compared to in situ burning.
Additive effect of multiple pharmacological chaperones on maturation of CFTR processing mutants (2007)

The most common cause of CF (cystic fibrosis) is the deletion of Phe(508) (DeltaF508) in the CFTR [CF TM (transmembrane) conductance regulator] chloride channel. One major problem with DeltaF508 CFTR is that the protein is defective in folding so that little mature protein is delivered to the cell surface. Expression of DeltaF508 CFTR in the presence of small molecules known as correctors or pharmacological chaperones can increase the level of mature protein. Unfortunately, the efficiency of corrector-induced maturation of DeltaF508 CFTR is probably too low to have therapeutic value and approaches are needed to increase maturation efficiency. We postulated that expression of DeltaF508 CFTR in the presence of multiple correctors that bound to different sites may have an additive effect on maturation. In support of this mechanism, we found that expression of P-glycoprotein (CFTR's sister protein) processing mutants in the presence of two compounds that bind to different sites (rhodamine B and Hoechst 33342) had an additive effect on maturation. Therefore we tested whether expression of DeltaF508 CFTR in the presence of combinations of three different classes of corrector molecules would increase its maturation efficiency. It was found that the combination of the quinazoline VRT-325 together with the thiazole corr-2b or bisaminomethylbithiazole corr-4a doubled the steady-state maturation efficiency of DeltaF508 CFTR (approx. 40% of total CFTR was mature protein) compared with expression in the presence of a single compound. The additive effect of the correctors on DeltaF508 CFTR maturation suggests that they directly interact at different sites of the protein.
A Lightweight People Counting Approach for Smart Buildings (2021)

Accurate and efficient people counting is essential to improve energy efficiency, space utility, and user comfort in smart buildings. However, existing people counting schemes suffer from an inherent limitation that is more or less intrusive or imprecise. Here we report a lightweight multi-objective approach for estimating indoor people counts. Specifically, we arrange an infrared array sensor at the indoor entrance, extract the spatial position of the moving targets in each frame, and then judge the entry and exit of the position sequence according to the target trajectories. Finally, experimental results show that accurate indoor people counts can be obtained.
Fluorescence-activated cell sorting and directed evolution of α-N-acetylgalactosaminidases using a quenched activity-based probe (qABP) (2013)

An α-N-acetylgalactosamine-containing quenched activity-based probe (qABP) was designed and successfully synthesized, and it was subsequently used in directed enzyme evolution experiments aided by fluorescence-activated cell sorting (FACS) for the discovery of an α-N-acetylgalactosaminidase variant with improved catalytic activity.
Effects of Two Estradiol/Norgestrel Combinations on the Ovulatory Pattern and on Sex Hormone Binding Globulin Capacity in Women Around Forty Years of Age (1984)

Thirteen women aged 36-46 years (mean 43) who were seeking contraceptive advice, were monitored for 3 months with basal body temperature (BBT) and were then treated for 3 months with CyclabilR (11 tablets of 2 mg estradiol valerate (E2) followed by 10 tablets of 2 mg E2 + 0.5 mg norgestrel). This treatment was immediately followed by another 3 months with CyclabilR + 2 mg E2. BBT revealed a spontaneous ovulatory rate of 89%. Cyclabil reduced the ovulatory rate, as measured with repeated serum progesterone analyses, to 37%, and Cyclabil + 2 mg E2 resulted in a marked reduction in the number of ovulations (3%). Both types of hormonal combination resulted in relatively small changes in Sex Hormone Binding Globulin Capacity. It is concluded that the addition of 2 mg E2 to CyclabilR causes a decrease in ovulation rate to such an extent that women using this combination run a relatively small risk of conceiving. One advantage over contraceptive steroids may be that the present combination contains a natural estrogen at a relatively low concentration.
