Abstract
We investigate the optical and Wide-field Survey Explorer (WISE) colors of “E+A” identified post-starburst galaxies, including a deep analysis of 190 post-starbursts detected in the 2 μm All Sky Survey Extended Source Catalog. The post-starburst galaxies appear in both the optical green valley and the WISE Infrared Transition Zone. Furthermore, we find that post-starbursts occupy a distinct region of [3.4]–[4.6] versus [4.6]–[12] WISE colors, enabling the identification of this class of transitioning galaxies through the use of broadband photometric criteria alone. We have investigated possible causes for the WISE colors of post-starbursts by constructing a composite spectral energy distribution (SED), finding that the mid-infrared (4–12 μm) properties of post-starbursts are consistent with either 11.3 μm polycyclic aromatic hydrocarbon emission, or thermally pulsating asymptotic giant branch (TP-AGB) and post-AGB stars. The composite SED of extended post-starburst galaxies with 22 μm emission detected with signal-to-noise ratio

requires a hot dust component to produce their observed rising mid-infrared SED between 12 and 22 μm. The composite SED of WISE 22 μm non-detections (S/N < 3), created by stacking 22 μm images, is also flat, requiring a hot dust component. The most likely source of the mid-infrared emission of these E+A galaxies is a buried active galactic nucleus (AGN). The inferred upper limits to the Eddington ratios of post-starbursts are 10−2–10−4, with an average of 10−3. This suggests that AGNs are not radiatively dominant in these systems. This could mean that including selections capable of identifying AGNs as part of a search for transitioning and post-starburst galaxies would create a more complete census of the transition pathways taken as a galaxy quenches its star formation.

Abstract
We present optical, near-infrared, and mid-infrared imaging of the host galaxy of FRB 121102 with the Gemini North telescope, the Hubble Space Telescope, and the Spitzer Space Telescope. The FRB 121102 host galaxy is resolved, revealing a bright star-forming region located in the outskirts of the irregular, low-metallicity dwarf galaxy. The star-forming region has a half-light radius of 0.68 kpc (

), encompassing the projected location of the compact (

pc), persistent radio source that is associated with FRB 121102. The half-light diameter of the dwarf galaxy is 5–7 kpc, and broadband spectral energy distribution fitting indicates that it has a total stellar mass of

. The properties of the host galaxy of FRB 121102 are comparable to those of extreme emission line galaxies, also known as hosts to some hydrogen-poor superluminous supernovae and long-duration γ-ray bursts. The projected location of FRB 121102 within the star-forming region supports the proposed connection of FRBs with newly born neutron stars or magnetars.
Colored Glasses to Mitigate Photophobia Symptoms Posttraumatic Brain Injury
Authors: Clark Joseph , Hasselfeld Kimberly , Bigsby Kathryn , Divine Jon 
Published: June 2017

Context: After a concussion or mild traumatic brain injury (mTBI), patients often suffer from light sensitivity, or photophobia, which contributes to decreased quality of life post-mTBI. Whereas sunglasses may provide some relief from photophobia, they are not practical indoors or in low light. A light-mitigation strategy can be easily used indoors as needed to optimize the relief. We have found that many photophobic patients experience relief using colored sunglasses.Objective: To provide the athletic trainer with a means and method to assess whether an athlete is suffering from photophobia after concussion and to determine if colored glasses provide relief.Design: Cross-sectional study.Setting: Rehabilitation clinic.Patients or Other Participants: Fifty-one patients being treated after concussion.Intervention(s): We assessed postconcussion patients for visual symptoms including photophobia and photosensitivity. Off-the-shelf glasses were used to determine whether specific colors provided relief from photophobia. Screening was done using a penlight and multiple pairs of colored glasses.Main Outcome Measure(s): Self-reported mitigation of photophobia symptoms and the specific color frequency that reduced symptoms in each individual.Results: Of the 39 patients studied who had visual symptoms, 76% complained of photophobia. Using glasses of 1 or more colors, symptoms were relieved in 85% of patients reporting photophobia. The colors that provided the most relief were blue, green, red, and purple. No adverse events were reported.Conclusions: An empirical assessment of frequency-specific photophobia is easy to perform. A traditional penlight is used to elicit photophobia and then the colored glasses are tested for optimal relief. Frequency-specific photophobia can be reduced with a strategy of light-mitigation therapy, including colored glasses, sunglasses, hats, and light avoidance. This, we believe, helps to improve the patient's quality of life and may aid in the recovery process. More work is needed to identify the best colors and methods of mitigating frequency-specific photophobia.

Published: June 2017

AbstractLet W be a compact simply connected triangulated manifold with boundary and let K ⊂ W be a subpolyhedron. We construct an algebraic model of the rational homotopy type of W\K out of a model of the map of pairs (K, K⋂∂W) ↪ (W, ∂W) under some high codimension hypothesis.We deduce the rational homotopy invariance of the configuration space of two points in a compact
manifold with boundary under 2-connectedness hypotheses. Also, we exhibit nice explicit models of these configuration spaces for a large class of compact manifolds.

Published: June 2017

ABSTRACT
Atomic force microscope (AFM)–based nanomechanics is one of the most promising tools for accessing the rubber–filler interface while providing not only structural information but also mechanical–property evaluation. An AFM-based static modulus map is used to close in on the understanding of the filler reinforcement effect. As an example, a famous Guth–Gold equation is verified by comparing tensile testing and AFM. Two different novel methods are also introduced to visualize viscoelastic quantities such as storage and loss moduli, loss tangent, relaxation modulus, and viscosity. The difference in segmental dynamics between a rubber matrix and an interfacial region will be reviewed.

Published: June 2017

Quantitative assessment of global and regional left ventricle function by means of myocardial strain estimation has been widely discussed as promising clinical diagnostic markers of left ventricular malfunction. These markers are provided to the clinicians without much feedback regarding their reliability, which may lead to erroneous diagnosis. Therefore, this study aims to classify the calculated strain curves into reliable or artefactual ones, before their clinical adaptation.A supervised machine learning approach is utilized for the classification process. A total of 6,552 strain curves were used, for which a visual labeling protocol was defined and utilized by two experts.An inter-observer labeling concordance of 93% was obtained, and a classification accuracy of 90% was achieved with a specificity of 92% and sensitivity of 78%.This classification tool may enhance the reliability of the estimations of global, transmural and regional strain curves, by automatically classifying them into physiological or artefactual curves.
El análisis existencial de Binswanger y la antropología orteguiana. Puntos de encuentro
Authors: Montesó Ventura Jorge 
Published: June 2017

En la aplicación de la Analítica Existencial heideggeriana al campo de la psiquiatría, Binswanger se vio con la necesidad de trascender ciertos aspectos de su pensamiento encaminando su planteamiento ontológico a una tematización de calado antropológico. Ésta interpretaría la “existencia” como la existencia de cada sujeto particular en su mundo vivido. Puesto que, para Binswanger, el mundo contemplaba al “otro”, el modelo de ser-en-el-mundo se ampliaría a ser-en-el-mundo-con-otros, por lo que el Sorge, orientado hacia uno mismo, se vería ampliada al Liebe, implicando ese amor a la alteridad. Estas progresiones despiertan no pocos arrimos al pensamiento orteguiano. Advertimos la cercanía a la idea de “mi vida”; a sus nociones antropológicas e intentos de catalogación sociológica; y la idea de “preocupación” como cuidado, entre el Sorge y el Liebe

AbstractMalignant tumor has become one of the hellish killers threatening the health of people around the world, its diagnosis and treatment has become the concerns of public. However, the optimal therapeutic dose, undesired side‐effect, and long‐term immune activation were key and bottleneck problems in tumor treatment. Herein, different batches of supramolecular therapeutic platforms, including vesicles, spherical nanoparticles, and cylindrical nanorods, with precise ratios of dye to drug (1:2) and multiple stimulus responsiveness were constructed by host‐guest complexation between cyanine‐camptothecin conjugates (IR780‐CPT2) and β‐cyclodextrin (β‐CD) pendent hydrophilic copolymers. The reduction responsiveness, near‐infrared photothermal conversion and singlet oxygen (1O2) generation performances endowed these platforms excellent cancer cells killing effect in both of in vitro cellular experiments and in vivo mice models. More importantly, without affecting the weight of mice, the maturation of dendritic cells, proliferation of T cells, up‐regulation of high mobility group protein B1, and reduction of immunosuppressive regulatory T cells were detected after employing a synergistic chemo‐photo therapy, demonstrating the body's immune effect was successfully activated. Thus, during the treatment of primary tumor, the distal tumor was also inhibited. We believe this work could provide a distinctive way to fabricate supramolecular theranostic platforms with different morphologies and improve antitumor and antimetastasis capabilities.

Published: October 2024

AbstractMetal–organic frameworks (MOFs) have attracted considerable attention in catalysis due to their exceptional structural and chemical tunability. However, high electrical conductivity is rare in MOFs, hindering their practical applications toward catalytic reactions. Recently, 2D topological MOFs stand out for the unique topologically nontrivial electronic structures. Particularly, their high electrical conductivity and chemical tunability make them promising candidates as high‐performance catalysts. In this study, theoretical investigations are conducted into the intrinsic electronic properties and chemical activity of a 2D topological Cu‐1,3,5‐tris(pyridyl)benzene (Cu‐TPyB) framework. It is found that the coordination environment of Cu with pyridyl groups plays a crucial role in modulating the electron density around the Fermi level, thereby enhancing the catalytic activity of Cu‐TPyB toward electrochemical hydrogen evolution reaction (HER). Furthermore, substituting the single embedded Cu atom with Cu3 and Cu4Bi3 clusters further increases the electron density around the Fermi level. Specifically, the Cu4Bi3‐TPyB framework exhibits superior HER activity, which is attributed to its high electron density contributed by the p orbitals of Bi and the d orbitals of Cu. This work introduces a novel approach for optimizing the catalytic activity of 2D MOFs and developing high‐performance catalysts.

AbstractN‐type organic semiconducting materials that are compatible in stretchable organic field effect transistors (OFETs) still lag in performance behind that of p‐type materials. Herein, a n‐type conjugated polymer (DPPF‐NTz) is reported that comprises a furan flanked diketopyrrolopyrrole (DPPF) as a monomer and napthobisthiadiazole (NTz) as a comonomer units, respectively, in a conjugated polymer backbone. The low band gap of 1.34 eV and suitable frontier energy levels allow its utilization in OFETs as an n‐type semiconducting material. Optimized bottom‐gate top contact OFETs based on chloroform and chloroform: o‐dichlorobenzene processed DPPF‐NTz showed a maximum electron mobility (µe) of 0.00042 cm2 V⁻¹ s⁻¹ and 0.00078 cm2 V⁻¹ s⁻¹, respectively, in devices annealed at 150 °C. Interestingly, upon mixing the DPPF‐NTz with a stretchable polymer, polystyrene‐block‐poly(ethylene‐ran‐butylene)‐block‐polystyrene (SEBS), yielded a stretchable semiconducting polymer composite, which displayed an enhanced µe of 0.0024 cm2 V⁻¹ s⁻¹ in devices annealed at 250 °C over pristine DPPF‐NTz. The improved µe and mechanical stretchability of the DPPF‐NTz: SEBS polymer blend over pristine DPPF‐NTz polymer is examined by nano‐mechanical atomic force microscopy. The research investigation finding provides a critical insight into the structural and nano‐mechanical properties of n‐type stretchable polymer semiconductors, which are essential for the development of next‐generation wearable OFETs.

AbstractPrecious metals are valuable materials for the chemical industry, but they are scarce and pose a risk of supply disruption. Recycling precious metals from waste is a promising strategy, here we tactfully utilize light irradiation as an environmental‐friendly and energy‐saving adjunctive strategy to promote the reduction of precious metal ions, thereby improving the adsorption capacity and kinetics. A newly light‐sensitive covalent organic framework (PP‐COF) was synthesized to illustrate the effectiveness and feasibility of this light auxiliary strategy. The equilibrium adsorption capacities of PP‐COF with light irradiation towards gold, platinum, and silver ions are 4729, 573, and 519 mg g−1, which are 3.3, 1.9, and 1.2 times the adsorption capacities under dark condition. Significantly, a filtration column with PP‐COF can recover more than 99.8 % of the gold ions in the simulated e‐waste leachates with light irradiation, and 1 gram of PP‐COF can recover gold from up to 0.15 tonne of e‐waste leachates. Interestingly, the captured precious metals by PP‐COF with light irradiation mainly exist in the micron‐sized particles, which can be easily separated by extraction. We believe this work can contribute to precious metal recovery and circular economy for recycling resources.

Published: October 2024

AbstractBipyridines represent a class of ligands renowned for their versatility and efficacy in numerous transition metal‐catalyzed reactions. Chiral bipyridine ligands are noted for their distinctive reactivity and stereoselectivity. In this work, we have designed and synthesized a class of bipyridine ligands endowed with an axially chiral scaffold. These ligands feature: (a) a precisely aligned coplanar bipyridine framework that is beneficial for metal chelation; (b) a spacious environment around the metal‐bipyridine complexes, capable of hosting substrates with substantial steric bulk; (c) a chiral pocket induced by the axially chiral architecture. These atropochiral planar bipyridine ligands were successfully applied in copper‐catalyzed ring‐opening reactions of cyclic diaryliodoniums with bulky secondary amines, achieving high efficiency and stereoselectivity that were unsuccessful in our previous efforts.
Molecular Weaving Towards Flexible Covalent Organic Framework Membranes for Efficient Gas Separations

Published: October 2024

AbstractCovalent organic frameworks (COFs) exhibit considerable potential in gas separations owing to their remarkable stability and tunable pore structures. Nevertheless, their application as gas separation membranes is hindered by limited size‐sieving capabilities and poor processability. In this study, we propose a novel molecular weaving strategy that combines hydroxyl polymers and 2D TpPa−SO3H COF nanosheets, achieving high gas separation efficiency. Driven by the strong electrostatic interactions, the hydroxyl chains thread through the COF pores, effectively weaving and assembling the composites to achieve exceptional flexibility and high mechanical strength. The penetrated chains also reduce the effective pore size of COFs, and combined with the “secondary confinement effect” stemming from abundant CO2 sorption sites in the channels, the PVA@TpPa−SO3H membrane demonstrates a remarkable H2 permeance of 1267.3 GPU and an H2/CO2 selectivity of 43, surpassing the 2008 Robson upper bound limit. This facile strategy holds promise for the manufacture of large‐area COF‐based membranes for small‐sized gas separations.
