On the Albian occurrence of Armigatus (Teleostei, Clupeomorpha) in America, a new species from the Tlayúa Lagerstätte, Mexico

A new fossil herring species is named in this work as Armigatus carrenoae, based on specimens from the marine Albian deposits of the Tlayúa Formation, near Tepexi de Rodríguez, Puebla, Central Mexico. The new species shows the most distinctive feature of the superorder Clupeomorpha, the abdominal scute series, as well as the order Ellimmichthyiformes, the posteriormost predorsal scutes laterally expanded, the mesoparietal condition of the skull, and the presence of the beryciform foramen in the anterior ceratohyal. Also, this species shares the diagnostic features of the genus Armigatus, the parasphenoid has an osteoglossid-like tooth patch and the predorsal scutes series is incomplete. Additionally, in this species, the posteriormost predorsal scutes exhibit a posterior spine, a character not observed before in Armigatus. This discovery is highly significant because it represents the oldest member of Armigatus, as well as the first record of the genus in America and reveals its unsuspected wide distribution during the late Early to Late Cretaceous throughout the Tethys Sea deposits, from America to the Middle East.

GANMcC: A Generative Adversarial Network With Multiclassification Constraints for Infrared and Visible Image Fusion

Visible images contain rich texture information, whereas infrared images have significant contrast. It is advantageous to combine these two kinds of information into a single image so that it not only has good contrast but also contains rich texture details. In general, previous fusion methods cannot achieve this goal well, where the fused results are inclined to either a visible or an infrared image. To address this challenge, a new fusion framework called generative adversarial network with multiclassification constraints (GANMcC) is proposed, which transforms image fusion into a multidistribution simultaneous estimation problem to fuse infrared and visible images in a more reasonable way. We adopt a generative adversarial network with multiclassification to estimate the distributions of visible light and infrared domains at the same time, in which the game of multiclassification discrimination will make the fused result to have these two distributions in a more balanced manner, so as to have significant contrast and rich texture details. In addition, we design a specific content loss to constrain the generator, which introduces the idea of main and auxiliary into the extraction of gradient and intensity information, which will enable the generator to extract more sufficient information from source images in a complementary manner. Extensive experiments demonstrate the advantages of our GANMcC over the state-of-the-art methods in terms of both qualitative effect and quantitative metric. Moreover, our method can achieve good fused results even the visible image is overexposed. Our code is publicly available at https://github.com/jiayi-ma/GANMcC.
Optical Rotation of Oriented Helices. III. Calculation of the Rotatory Dispersion and Circular Dichroism of the Alpha‐ and 310‐Helix

We have carried out a calculation of the optical rotatory dispersion (ORD) of α‐and 310‐helices which is essentially complete within the limitations of the Kirkwood approximation and its extensions. This treatment predicts that right‐handed helices will exhibit three rotatory bands at wavelengths greater than 190 mμ. The sign and position of these predicted bands are in good agreement with experiment. The predicted rotational strengths do not agree so well, but are in sufficiently good accord to provide strong support to the assignment of the longest‐wavelength band to the amide nπ* transition, and the shortest‐wavelength band thus far observed to a composite band due both to the perpendicular‐polarized exciton component and to the intrinsic rotational strength of the NV 1 transition. Calculation of the ORD and CD (circular dichroism) of the α‐helix from the calculated rotational strengths gives results in fair agreement with experiment, especially when the nπ* rotational strength is adjusted to agree with that observed in CD experiments. An analysis of the calculated ORD curves according to the Moffitt—Yang and Shechter—Blout procedures leads to values for the parameters in these equations which agree well with experiment in the case of the α‐helix. A similar treatment of the 310‐helix indicates that this helix can be distinguished from the α‐helix by: (a) appreciably more positive rotations in the visible region, (b) appreciably larger absolute values of b 0, A(α, ρ)225 and A(α, ρ)193. The dependence of various rotatory parameters on the length of the helix has been studied. The dispersion parameters b 0, A(α, ρ)225 and A(α, ρ)193, as well as the depth of the 233 mμ trough appear to be the least sensitive to chain length. The magnitude of the maximum at 198 mμ, however, seems quite chain‐length dependent, and therefore is probably not suitable as a measure of helix content.
Thermophysical Properties of Irradiated Polymers

The effect of ionising radiation on the specific heat, thermal conductivity, thermal diffusivity, and density of partially crystalline (polyethylene, polypropylene, polytetrafluoro-ethylene) and of amorphous polymers (polystyrene, poly(methyl methacrylate)) is discussed. Analytical models of the mechanism of heat conduction, and the development of anisotropic thermal conductivity in amorphous polymers, are examined. The influence of ionising radiation on the thermophysical properties of composite materials is analysed. 79 references.
Refractive results, visual quality and patient satisfaction with a new trifocal intraocular lens design

Aim: To evaluate the outcomes after bilateral implantation of a new trifocal intraocular lens (IOL). Materials and Methods: The study included patients with visually significant cataract that underwent bilateral implantation of the Acriva Trinova Sinusoidal Trifocal IOL. The preoperative corrected distance visual acuity (CDVA) and postoperative uncorrected distance visual acuity (UDVA), CDVA, uncorrected intermediate (UIVA) and near visual acuities (UNVA) along with manifest refractions were assessed at 1 month and 6 months after cataract surgery. The defocus curve and contrast sensitivity (CS) were evaluated at the 6th month visit. Patient satisfaction and incidence of dysphotopic symptoms were assessed. Results: The study enrolled a total of 60 eyes of 30 patients, 10 males and 20 females aged 61.78± 8.73 years (range, 45 to 78 years). 90% of the patients (n: 27) achieved a binocular UIVA of 0.1 LogMAR or better at the 6-month visit while, 96.7% (n:29) patients had a binocular UNVA of 0.1 LogMAR or better in the same postoperative visit. The CS results were within the the range of normality at 6 months post-surgery. 6.7% of patients reported marked halo around light sources and 3.3% reported glare that interferes with nighttime driving. 96.6% of the patients reported spectacle independence for all distances and rated their visual function and quality satisfactory at all distances. Conclusion: Bilateral implantation of the Acriva Trinova Sinusoidal Trifocal IOL seems to provide effective restoration of visual function at all distances after cataract surgery in the majority of patients. Contrast sensitivity results and low incidence of dysphotopic phenomena might be associated with high patient satisfaction.
Comparison of Two Transmission Electron Microscopy Methods to Visualize Drug-Induced Alterations of Gram-Negative Bacterial Morphology

In this study, we optimized and compared different transmission electron microscopy (TEM) methods to visualize changes to Gram-negative bacterial morphology induced by treatment with a robenidine analogue (NCL195) and colistin combination. Aldehyde-fixed bacterial cells (untreated, treated with colistin or NCL195 + colistin) were prepared using conventional TEM methods and compared with ultrathin Tokuyasu cryo-sections. The results of this study indicate superiority of ultrathin cryo-sections in visualizing the membrane ultrastructure of Escherichia coli and Pseudomonas aeruginosa, with a clear delineation of the outer and inner membrane as well as the peptidoglycan layer. We suggest that the use of ultrathin cryo-sectioning can be used to better visualize and understand drug interaction mechanisms on the bacterial cell membrane.
Highly-Accurate Community Detection via Pointwise Mutual Information-Incorporated Symmetric Non-Negative Matrix Factorization

Community detection, aiming at determining correct affiliation of each node in a network, is a critical task of complex network analysis. Owing to its high efficiency, Symmetric and Non-negative Matrix Factorization (SNMF) is frequently adopted to handle this task. However, existing SNMF models mostly focus on a network's first-order topological information described by its adjacency matrix without considering the implicit associations among involved nodes. To address this issue, this study proposes a Pointwise mutual information-incorporated and Graph-regularized SNMF (PGS) model. It uses a) Pointwise Mutual Information to quantify implicit associations among nodes, thereby completing the missing but crucial information among critical nodes in a uniform way; b) graph-regularization to achieve precise representation of local topology, and c) SNMF to implement efficient community detection. Empirical studies on eight real-world social networks generated by industrial applications demonstrate that a PGS model achieves significantly higher accuracy gain in community detection than state-of-the-art community detectors.
Characterizing the aerobic and anaerobic microbial activities in surface and subsurface soils

Studies were conducted to characterize the aerobic and anaerobic microbial activities in surface and subsurface soils of septic tank tile fields. Under aerobic conditions, the indigenous microflora in the soils degraded the natural substrates and many of the synthetic chemicals tested. Half-lives (t1/2) for the biodegradation (14CO2 production) of glucose and glutamic acid ranged from 2 to 5 h in surface soils and from 8 to 25 h in subsurface soils. Degradation of stearic acid was slower in both surface (t1/2 = 118 h) and subsurface (t1/2 = 82 to 312 h) soils. 14CO2 evolution from the synthetic chemicals methyl parathion and 2,4-D was more variable than that from the natural substrates and occurred in the surface soil but in only one of the two subsurface soils tested. The aerobic biodegradation of nitrilotriacetate (NTA) was studied only in the two subsurface soils from the tile fields. NTA was mineralized in both soils and the half-life for 14CO2 production ranged from 86 to 161 h. When the surface and subsurface soils were incubated under anaerobic (nitrate-reducing) conditions, active denitrification by the indigenous microflora was observed. In surface soils, denitrification occurred immediately after an anaerobic preincubation (12 to 24 h) and the N2O production curve was linear. In subsurface soils, N2O production occurred only after 32 to 44 h of anaerobic incubation and was described by an S-shaped curve. Biodegradation of the natural substrates (glucose, glutamic and acetic acid) under these anaerobic conditions ranged from 1 to 2 h for the surface soil to 2 to 20 h for subsurface soils. The half-life for the anaerobic mineralization of NTA ranged from 49 to 125 h in the subsurface soils. The results indicate that the indigenous microflora in the subsurface have lower activities than do those in surface soils; however, the subsurface microflora can effectively mineralize natural and certain synthetic substrates under aerobic and denitrifying conditions.
Calculation of crystal field splittings in distorted coordination polyhedra: spectra and thermodynamic properties of minerals

Summary A simple method has been developed for calculating the d-orbital energy levels of transition-metal ions in coordination polyhedra with both orthogonal and non-orthogonal distortions, using equations based on those derived by Ballhausen (1954). The input data are atomic coordinates, a standard value of the crystal field splitting parameter Δ at known metal-ligand distance, and the ratio of radial integrals B 2/B 4, which is approximately constant for a given ion. The method can be applied to polyhedra containing different ligands. Application of the equations to the Mn3+ (M3) site in piemontite and the Fe2+ (M2) site in orthopyroxene gives calculated transition energies in good agreement with the observed band energies. The calculations permit definite assignment of the great majority of d-d absorption bands even in multi-site phases, and enable discrimination of crystal-field and charge-transfer bands in mineral spectra. They also throw light on the fine structures of both oxygen → metal and metal → metal charge-transfer bands, and allow the calculation of crystal-field stabilization enthalpy and electronic entropy. The latter is a previously neglected energy term that contributes significantly to the energetics of reactions within and between phases containing transition-metal ions.
Risk, Stock, and Bond Value in Indonesia Public Companies

Indonesian stock market are unpopular sources of capital for companies. Stock market have 2 main products that is stock and bond. Bond is much more unpopular than stock. This study will examine the relations between risk, stock return, and bond returns relation in Indonesian Public Companies. Sample are 51 companies that listed in Indonesian Stock Exchange and issues bond during 2011-2018. Risk as endogen variable measured by Altman Z score. Stock values as exogenous variables using stock returns and dividend yields as indicators. Endogen variable bond value having bond returns and Yield to maturity as measurements. Data then analysed using warp PLS. The results shows that stock returns are mediating the relations between bankruptcy risk and bond return in Indonesia. This is consistent with optimal capital structure and financial distress theory. Companies usually choose to issued stock rather than bond. If it choose both, it will be like to use stock rather than bond. Hence, investor also choose in the stock when companies risk is higher rather than bond. Keywords—bankruptcy risk, stock value, bond value

Sickness Presenteeism in Shift and Non-Shift Nurses: Using the Fifth Korean Working Conditions Survey

Nurses have reported higher rates of sickness presenteeism than other workers, which is particularly problematic because this problem is linked to care quality and patient safety. This secondary data analysis study aimed to identify the prevalence of sickness presenteeism and explore related factors among shift and non-shift nurses using the Fifth Korean Working Conditions Survey. A total of 272 nurses in Korean hospitals were included. The survey included questions on working conditions, health status, and sickness presenteeism. A multivariate logistic regression was used to identify associated factors of sickness presenteeism. Overall, 21.8% of the participants reported experiencing sickness presenteeism; shift nurses experienced more sickness presenteeism than non-shift nurses. Sickness presenteeism was greater in shift nurses who did not have rest breaks during work and in nurses who experienced quick return. Additionally, the odds of sickness presenteeism were approximately four times greater in shift nurses who experienced sleep disturbance and about four times higher in shift nurses who experienced health problems. Among non-shift nurses, the odds of sickness presenteeism were about 15 times greater in those who worked ≥53 h per week. Nurse managers and administrators should prevent sickness presenteeism in hospital nurses to provide quality care and enhance productivity.
Kinetics of the dissociation of nickel−2-methyl-8-hydroxyquinoline in water and surfactant micelles

The kinetics of the dissociation of the Ni complex (NiL 2 ) of 2-methyl-8-hydroxyquinoline (HL) by H + was studied in water and in micelles formed by the surfactants Triton X-100 and Brij 35 (neutral), sodium dodecyl sulfate (SDS ; anionic) and cetyltrimethylammonium nitrate (CTAN ; cationic). The rate limiting step in all the media is the dissociation of the NiL + complex, which in micelles occurs predominantly at the aqueous-micellar interface. The dissociation rate constant shows little variation between H 2 O, Triton X-100, Brij 35, and CTAN but is about 100 times larger in SDS. The activation parameters are identical in H 2 O and in the neutral micelles, with the entropies of activation being positive in line with the proposed rate limiting step. These parameters are quite different in SDS and CTAN. The enthalpy of activation is 5 times smaller in SDS compared to H 2 O and neutral micelles with a negative entropy of activation. Surprisingly, the enthalpy of activation is also smaller in CTAN, being about 1.6 times smaller than the value in H 2 O with a much smaller entropy of activation as well. The activation parameters in SDS strongly suggest the adsorption of NiL + on the negatively charged micellar surface. The smaller enthalpy and entropy of activation in the case of CTAN compared to H 2 O may stem from the stabilization of the activated complex through association with CTA + . The offsetting contributions from the enthalpy and entropies of activation in CTAN lead to an apparent similarity in the dissociation rate constant in CTAN and aqueous media.
Interplay Between Surface and Buffer Traps in Governing Breakdown Characteristics of AlGaN/GaN HEMTs—Part II

Physical insights into the complex interplay of surface and (GaN) buffer traps governing breakdown characteristics of AlGaN/GaN HEMTs are developed by well-calibrated TCAD simulations. Impact of surface traps in correlation with 1) acceptor traps in case of Fe doping and 2) self-compensating traps (corresponding to C doping) in the GaN buffer on breakdown characteristics of AlGaN/GaN HEMTs is discussed. The explorations include defect-related traps as well as traps induced by intentional buffer doping by carbon/iron. The computational findings corroborate well with the experimentally observed electric field profile for devices with different buffer doping conditions. Developed insights have allowed to discuss the collective impact of surface as well as buffer traps on device design to improve breakdown characteristics.
Prognostic and Clinicopathological Significance of CCND1/Cyclin D1 Upregulation in Melanomas: A Systematic Review and Comprehensive Meta-Analysis

Simple Summary The incidence of cutaneous melanoma is increasing worldwide, currently responsible for 287,723 new cases and 60,712 deaths per year (GLOBOCAN, IARC, WHO). It should be also highlighted that some less frequent subtypes of melanomas—i.e., acral, uveal, and mucous melanoma—are responsible for significant morbidity associated with metastasis, responding typically worse to newer therapies. Therefore, new biomarkers are needed to improve the prognosis in individual patients. In this sense, the present study showed that CCND1/cyclin D1 upregulation is a common molecular oncogenic alteration in melanomas that probably favors the growth and expansion on cutaneous primary melanomas. Furthermore, immunohistochemical cyclin D1 overexpression strongly predicted a higher Breslow thickness, currently considered the most relevant prognostic factor in individual patients with melanomas. Finally, special attention should be paid to the CCND1/cyclin D1 complex in mucosal melanomas, whose upregulation was strikingly altered. Abstract Our objective was to evaluate the prognostic and clinicopathological significance of cyclin D1 (CD1) overexpression/CCND1 amplification in melanomas. We searched studies published before September 2019 (PubMed, Embase, Web of Science, Scopus). We evaluated the quality of the studies included (QUIPS tool). The impact of CD1 overexpression/CCND1 amplification on overall survival and relevant clinicopathological characteristic were meta-analyzed. We performed heterogeneity, sensitivity, small-study effects, and subgroup analyses. Forty-one studies and 3451 patients met inclusion criteria. Qualitative evaluation demonstrated that not all studies were performed with the same rigor, finding the greatest risk of bias in the study confounding domain. Quantitative evaluation showed that immunohistochemical CD1 overexpression had a statistical association with Breslow thickness (p = 0.007; OR = 2.09,95% CI = 1.23–3.57), significantly higher frequency of CCND1/cyclin D1 abnormalities has been observed in the primary tumor compared to distant metastases (p = 0.004), revealed also by immunohistochemical overexpression of the protein (p < 0.001; OR = 0.53,95% CI = 0.40–0.71), while the CCND1 gene amplification does not show association (p = 0.43); while gene amplification, on the contrary, appeared more frequently in distant metastases (p = 0.04; OR = 1.70,95% CI = 1.01–2.85) and not in the primary tumor. In conclusion, CCND1/cyclin D1 upregulation is a common molecular oncogenic alteration in melanomas that probably favors the growth and expansion of the primary tumor. This upregulation is mainly consequence to the overexpression of the cyclin D1 protein, and not to gene amplification.
