theoretical and experimental study of the deposition of dielectric stacks on twin-hole silica fibers for implementation of compact all-fiber resonators

<p>This dataset includes the Matlab code to engineer theoretically a&nbsp;Bragg stack made of different dielectric layers. By changing the number of alternating stacks,&nbsp;their thickness and the refractive index of each layer it is possible to obtain&nbsp;the transmission curve of the Bragg stack versus the wavelength&nbsp;of the light in a certain range of values. The dataset includes also the experimental measurements of the resonances related to one of the fabricated compact resonators (based on the twin-hole fiber not poled) and obtained sweeping the wavelength of the input light injected through&nbsp;one of the two Bragg stacks and collecting the power at the exit of the other Bragg stack. &nbsp;</p>

Usage and Attribution of Stack Overflow Code Snippets in GitHub Projects — Supplementary Material

<p><em>Background:</em> Stack Overflow (SO) is the largest Q&amp;A website for software developers, providing a huge amount of copyable code snippets. Using those snippets raises various maintenance and legal issues. SO&rsquo;s license (CC BY-SA 3.0) requires attribution, i.e., referencing the original question or answer, and requires derived work to adopt a compatible license. While there is a heated debate on SO&rsquo;s license model for code snippets and the required attribution, little is known about the extent to which snippets are copied from SO without proper attribution.</p> <p><em>Aim:</em> Our main goal was to analyze how often code from SO posts is used in public GitHub projects, but not attributed as required by the license. Further, we wanted to investigate if developers are aware of SO&rsquo;s license and its implications, and to what degree they adhere to the attribution requirements defined in SO&rsquo;s terms of service.</p> <p><em>Method:</em> We present results of a large-scale empirical study analyzing the usage and attribution of non-trivial Java code snippets from SO answers in public GitHub projects. We followed three different approaches to triangulate an estimate for the ratio of unattributed usages and conducted two online surveys with software developers to complement our results.</p> <p><em>Results:</em> For the different sets of projects that we analyzed, the amount of projects containing files with a reference to SO varied between 3.3% and 11.9%. We found that at most 1.8% of all analyzed repositories containing code from SO used the code in a way compatible with CC BY-SA 3.0. Moreover, we estimate that at most a quarter of the copied code snippets from SO are attributed as required, i.e., using a link in a source code comment. About half of the surveyed developers admitted copying code from SO without attribution. Furthermore, about two thirds of them were not aware of the license of SO code snippets and its implications.</p>

Room Temperature NIR Phosphorescence from C64 Nanographene Tetraimide by π-Stacking Complexation with Pt(II)Porphyrin

<p>Additional data to report <a href="https://doi.org/10.1002/anie.202406353">https://doi.org/10.1002/anie.202406353</a>:</p> <p>Near Infrared (NIR) phosphorescence at room temperature is challenging to achieve for organic molecules due to a negligible spin-orbit coupling and a low energy gap leading to fast non-radiative transitions. Here, we show a supramolecular host&ndash;guest strategy to harvest the energy from the low-lying triplet state of C<sub>64</sub> nanographene tetraimide <strong>1</strong>. <sup>1</sup>H NMR and X-ray analysis confirmed the 1:2 stoichiometric binding of a Pt(II)porphyrin on the two &pi;-surfaces of <strong>1</strong>. While the free <strong>1</strong> does not show emission in the NIR, the host&ndash;guest complex solution shows NIR phosphorescence at 77 K. Further, between 860&ndash;1100 nm room temperature NIR phosphorescence (<em>&lambda;</em><sub>max</sub> = 900 nm, <em>&tau;</em><sub>avg</sub> = 142 &micro;s) was observed for a solid-state sample drop-casted from a preformed complex in solution. Theoretical calculations reveal a non-zero spin-orbit coupling between isoenergetic S<sub>1</sub> and T<sub>3 </sub>of &pi;-stacked [<strong>1</strong>&middot;Pt(II)porphyrin] complex. External heavy atom induced spin-orbit coupling along with rigidification and protection from oxygen in the solid state promotes both the intersystem crossing from the first excited singlet state into the triplet manifold and the NIR phosphorescence from the lowest triplet state of&nbsp;<strong>1</strong>.</p>

BRAIN Journal-About the Design of QUIC Firefox Transport Protocol-Figure 1. TLS vs QUIC protocol stack

<p>QUIC addresses many network problems such as the Head Of Line (HOL) blocking as well as the TCP reconnection over a subnet/network change. In addition, QUIC has many features such as connection IDs, which can overcome the challenge of changing networks. In this way, if someone switches from a WIFI network to a cellular network, the connection to the server will not be broken or lost. Paper (Langley and Chang, 2016) described the QUIC crypto protocol, representing the part of QUIC that provides transport security to a connection. The QUIC crypto protocol is now replaced by TLS 1.3. Currently, QUIC provides security of TLS 1.3 (in an experimental stage), considered the highest security standards for the communication protocols (Valsorda; 2016).&nbsp;</p> <p>Figure 1 describes the TLS vs. QUIC protocol user level stack in the context of application layer and transport layer.</p>

SOTorrent: Reconstructing and Analyzing the Evolution of Stack Overflow Posts — Supplementary Material

<p>Stack Overflow is the most popular question-and-answer website for software developers, providing a large amount of code snippets and free-form text on a wide variety of topics. Like other software artifacts, questions and answers on Stack Overflow evolve over time, for example when bugs in code snippets are fixed, code is updated to work with a more recent library version, or text surrounding a code snippet is edited for clarity. To be able to analyze how content on Stack Overflow evolves, we built <em>SOTorrent</em>, an open dataset based on the official Stack Exchange data dump. <em>SOTorrent </em>provides access to the version history of Stack Overflow content at the level of whole posts and individual text or code blocks.</p> <p>This dataset has been retrieved from <em>SOTorrent </em>using the following scripts:</p> <p><a href="https://doi.org/10.5281/zenodo.1201679">https://doi.org/10.5281/zenodo.1201679</a></p> <p>For the MSR 2018 paper about SOTorrent, we used the following scripts to analyze the data:</p> <p><a href="https://doi.org/10.5281/zenodo.1201706">https://doi.org/10.5281/zenodo.1201706</a></p> <p>The files&nbsp;<em>sample_before_10.ods</em> and <em>sample_after_10.ods</em> contain our qualitative analysis of 50 comments that were made up to 10 minutes before/after an edit.</p>

Ternary π–π Stacking Complexes by Allosteric Regulation in Multilayer Nanographenes

<p>Additional data to report <a href="https://doi.org/10.1021/jacs.4c11119">https://doi.org/10.1021/jacs.4c11119</a>:</p> <p>Construction of &pi;&ndash;&pi; stacking supramolecular complexes with more than two components is challenging due to the weak and directionless nature of dispersion interactions. Here we report ternary complexes of a ditopic nanographene tetraimide (<strong>1</strong>), &alpha;-substituted phthalocyanine (<strong>Pc</strong>) and polyaromatic hydrocarbons (PAHs) in solution and crystalline state via allosteric regulation. Binding of one <strong>Pc</strong> give rise to significant distortion and conformational changes in <strong>1</strong> that in turn lead to the inhibition of the second binding of <strong>Pc</strong>. The conformational changes associated with first binding allowed an allosteric binding of a third component (PAHs) to form ternary complexes in solution. <sup>1</sup>H NMR titration revealed a moderately high thermodynamic stability for the ternary complexes in CDCl<sub>3</sub>. Competition between allosterically regulated ternary complexes ([<strong>Pc&middot;1</strong>&middot;PAH]) and 1:2 stoichiometric binary complexes of <strong>1</strong> with PAHs ([PAH&middot;<strong>1</strong>&middot;PAH]) were elucidated. Further, selective formation of ternary complexes in solution led to the generation of ternary cocrystals from a 1:1:1 mixture of three components in solution. Our work shows that large &pi;-conjugated nanographenes designed with allosteric recognition sites allow the construction of multilayer ternary complexes in solution and solid-state even with dispersive &pi;&ndash;&pi; interactions.</p>

'Invisible' Molecular Dynamics Revealed for a Conformationally Chiral π-Stacked Perylene Bisimide Foldamer

<p>Additional data to report <a href="https://doi.org/10.1002/anie.202414069">https://doi.org/10.1002/anie.202414069</a>:</p> <p><a name="_Hlk172654864"></a>Whilst energetic and kinetic aspects of folding processes are meanwhile well understood for natural biomacromolecules, the folding dynamics in so far studied artificial foldamer counterparts remain largely unexplored. This is due to the low energy barriers between their conformational isomers that make the dynamic processes undetectable with conventional methods such as UV/vis absorption, fluorescence, and NMR spectroscopy, making such processes &lsquo;invisible&rsquo;. Here we present an asymmetric perylene bisimide dimer (bis-PBI <strong>1</strong>) that possesses conformational chirality in its folded state. Owing to the large interconversion barrier (&ge;&nbsp;116&nbsp;kJ&nbsp;mol<sup>&ndash;1</sup>), four stereoisomers could be separated and isolated. Since the interconversion between these stereoisomers requires the foldamer to first open and then to re-fold, the transformation of one stereoisomer into others allowed us to &lsquo;visualize&rsquo; the dynamics of folding with time and determine its lifetimes and the energetic barriers associated with the folding process. Supported by quantum chemical calculations, we identified the open structure to be only a fleeting metastable state of higher energy. Our experimental observation of the kinetics associated with the molecular dynamics in the PBI foldamer advances the fundamental understanding of folding in synthetic foldamers and paves the way for the design of smart functional materials.</p>

Mid to late Pleistocene IODP Expedition 354 Bengal Fan 8⁰ North transect age models, sedimentation rate stack, magnetic susceptibility stack, and XRF data

<p>Mid to late Pleistocene age models for the International Ocean Discovery Program (IODP) Expedition 354 8⁰ North drilling transect.&nbsp; Stacked records of sedimentation rates and magnetic susceptibility.&nbsp; U-channel XRF scans of calcareous clay sediments at Site U1452.</p> <p>&nbsp;</p> <p><strong>Abstract:</strong></p> <p>We investigate chronology and age uncertainty for the middle to upper Pleistocene lower Bengal Fan using a novel age-depth modeling approach that factors litho-, magneto-, bio-, cyclo-, and seismic stratigraphic constraints, based on results from the International Ocean Discovery Program Expedition 354 Bengal Fan and analysis of the GeoB97-020/027 seismic line. The initial chronostratigraphic framework is established using regionally extensive hemipelagic sediment units and only age-depth models of fan deposits that respect the superposition of channel-levee systems between sites are accepted. In doing so, we reconstruct signals of regional sediment accumulation rate and lithogenic sediment input through the perspective of a two-dimensional ~320 km transect at 8⁰ N that are consistent with more distal and more ambiguous regional records. This chronology allows us to discuss the depositional history of the middle to upper Pleistocene lower Bengal Fan within the context of sea level, climate, and tectonic controls. We hypothesize, based on the timing of accumulation rate changes, that progradation and intensification of the Bengal Fan&rsquo;s channel-levee system at 8⁰ N was largely driven by increases in sea level amplitude during this time. However, it is also possible this progradation was influenced by changes in Pleistocene climate and increased Himalayan erosion rates, driving greater sediment flux to the fan.</p> <p>&nbsp;</p>
