title: Modelling of excitation propagation on computer models of insoles colonised by fungal mycelium. Videos and potential difference recordings.

description: We used an artistic image of the mycelium network projected onto a $364 \times 985$ nodes grid. <br> The original image $M=(m_{ij})_{1 \leq j \leq n_i, 1 \leq j \leq n_j}$, $m_{ij} \in \{ r_{ij}, g_{ij}, b_{ij} \}$, where $n_i=364$ and $n_j=985$, and $1 \leq r, g, b \leq 255$, was converted to a conductive matrix $C=(m_{ij})_{1 \leq i,j \leq n}$ derived from the image as follows: $m_{ij}=1$ if $r_{ij}&gt;170$, $g_{ij}&gt;170$ and $b_{ij}&lt;200$; a dilution operation was applied to $C$. FitzHugh-Nagumo (FHN) equations is a qualitative approximation of the Hodgkin-Huxley model of electrical activity of living cells:<br> \begin{eqnarray}<br> \frac{\partial v}{\partial t} & = & c_1 u (u-a) (1-u) - c_2 u v + I + D_u \nabla^2 \\<br> \frac{\partial v}{\partial t} & = & b (u - v),<br> \end{eqnarray}<br> where $u$ is a value of a trans-membrane potential, $v$ a variable accountable for a total slow ionic current, or a recovery variable responsible for a slow negative feedback, $I$ {is} a value of an external stimulation current. The current through intra-cellular spaces is approximated by<br> $D_u \nabla^2$, where $D_u$ is a conductance. The term $D_u \nabla^2 u$ governs a passive spread of the current. The terms $c_2 u (u-a) (1-u)$ and $b (u - v)$ describe the ionic currents. The term $u (u-a) (1-u)$ has two stable fixed points $u=0$ and $u=1$ and one unstable point $u=a$, where $a$ is a threshold of an excitation. We integrated the system using the Euler method with the five-node Laplace operator, a time step $\Delta t=0.015$ and a grid point spacing $\Delta x = 2$, while other parameters were $D_u=1$, $a=0.13$, $b=0.013$, $c_1=0.26$. We controlled excitability of the medium by varying $c_2$ from 0.05 (fully excitable) to 0.015 (non excitable). Boundaries are considered to be impermeable: $\partial u/\partial \mathbf{n}=0$, where $\mathbf{n}$ is a vector normal to the boundary. To record dynamics of excitation in the network, as if in laboratory experiments, we simulated electrodes by calculating a potential $p^t_x$ at an electrode location $x$ as $p_x = \sum_{y: |x-y|&lt;2} (u_x - v_x)$. Configuration of electrodes $1, \cdots, 16$ is shown in Fig.~\ref{fig:mycelium}c. Time-lapse snapshots provided in the paper were recorded at every 100\textsuperscript{th} time step, and we display sites with $u &gt;0.04$; videos and figures were produced by saving a frame of the simulation every 100\textsuperscript{th} step of the numerical integration and assembling the saved frames into the video with a play rate of 30 fps.

title: The number of enterprises in Poland and EU countries (in thousands) in 2019

description: Enterprises from the SME sector constitute the majority of companies in Poland and in the European Union countries. However, the structure of domestic enterprises in terms of size and industry differs from the EU average. Taking into account the nature of the business in Poland, more companies operate in trade, and lower in services. However, it should be emphasized that the structure of domestic enterprises is systematically changing, and thus the number of micro-enterprises is decreasing and there is an increase in service companies. The following data contains information about the number of enterprises in Poland and EU countries (in thousands) in 2019.

title: Supplementary Material for: Fabrication and Characterization of Silk Fibroin-Based Nanofibrous Scaffolds Supplemented with Gelatin for Corneal Tissue Engineering

description: Tissue engineering is a promising approach to overcome the severe worldwide shortage of healthy donor corneas. In this work, we have developed a silk-gelatin composite scaffold using electrospinning and permeation techniques to achieve the properties comparable to cornea analog. In particular, we present the fabrication and comparative evaluation of the novel gelatin sheets consisting of silk fibroin nanofibers, which are prepared using silk fibroin (SF) (in formic acid) and SF (in aqueous) electrospun scaffolds, for its suitability as corneal stromal analogs. All the fabricated samples were treated with ethanol vapor (T) to physically crosslink the silk nanofibers. Micro/nano-scale features of the fabricated scaffolds were analyzed using scanning electron microscopy micrographs. Fourier transform infrared spectroscopy revealed characteristic peaks of polymeric functional groups and modifications upon ethanol vapor treatment. Transparency of the scaffolds was determined using UV-visible spectra. Among all the fabricated samples, the gelatin-permeated SF (in formic acid; T) scaffold showed the highest level of transparency, i.e., 77.75 ± 2.3%, which is similar to that of the native cornea (∼70%–90% [variable with age group]) with healthy acute vision. Contact angle of the samples was studied to estimate the hydrophilicity of the scaffolds. All the scaffolds except non-treated SF (in aqueous; NT) were found to be significantly stable up to 14 days when incubated in phosphate buffered saline at 37°C. Treated samples showed significantly better stability, both physically and microscopically, in comparison to nontreated samples. Proliferation and viability assays of rabbit corneal fibroblast cells (SIRC) and mouse fibroblast cells (L929 RFP) when cultured on fabricated scaffolds revealed remarkable cellular compatibility with gelatin-permeated SF (in formic acid; T) scaffolds compared to SF (in aqueous; T). Unlike other reports in the existing literature, this work presents the design and development of a nanofibrous silk-gelatin composite that exhibits acceptable transparency, cellular biocompatibility, as well as improved mechanical stability comparable to that of native cornea. Therefore, we anticipate that the fabricated novel scaffold is likely to be a good candidate for corneal tissue construct. Moreover, among the fabricated scaffolds, the outcomes depict gelatin-permeated SF (in formic acid; T) composite scaffold to be a better candidate as a corneal stromal analog that carries properties of both the silk and gelatin, i.e., optimal transparency, better stability, and enhanced cytocompatibility.

title: The structure of the enterprise sector by size in Poland and the EU-28 in 2017

description: The majority (99.8%) of companies in the EU countries are micro, small and medium-sized enterprises - see chart. The situation is similar in Poland, but the structure of the SME sector is slightly different from that observed in the EU. In Poland, the share of micro-enterprises in the total number of enterprises is higher than in the EU countries (95.5% compared to 92.9% in the EU), and the share of small enterprises - almost half lower (3.4% and in the EU 6.0%) . The share of medium-sized enterprises in SMEs in the country is close to the EU average (Poland - 0.9%, EU - 1.0%).

title: Supplementary Material for: Ramucirumab for Patients with Intermediate-Stage Hepatocellular Carcinoma and Elevated Alpha-Fetoprotein: Pooled Results from Two Phase 3 Studies (REACH and REACH-2)

description: <b><i>Background:</i></b> Intermediate-stage hepatocellular carcinoma (HCC), as defined by Barcelona Clinic Liver Cancer (BCLC) stage B, is heterogeneous in terms of liver function and tumor burden. REACH and REACH-2 investigated ramucirumab in patients with HCC after prior sorafenib, with REACH-2 enrolling only patients with baseline α-fetoprotein (AFP) ≥400 ng/mL. An exploratory analysis of outcomes by BCLC stage was performed. <b><i>Methods:</i></b> A pooled meta-analysis of independent patient data (stratified by study) from REACH (AFP ≥ 400 ng/mL) and REACH-2 was performed. All patients had Child-Pugh A, Eastern Cooperative Oncology Group performance status 0–1, prior sorafenib treatment, and either HCC BCLC stage B (refractory/not amenable to locoregional therapy) or BCLC stage C. Patients were randomized to ramucirumab 8 mg/kg or placebo every 2 weeks. Median overall survival (OS) and progression-free survival were estimated by the Kaplan-Meier method. Treatment effects in BCLC stage B and C were evaluated by Cox proportional-hazards model; prognosis of BCLC staging for OS was evaluated by multivariate Cox proportional-hazards model. Tumor responses were evaluated according to Response Evaluation in Solid Tumors v1.1. Liver function was assessed with albumin-bilirubin score. <b><i>Results:</i></b> Baseline characteristics were generally balanced between treatment arms in each BCLC stage. BCLC staging trended as an independent prognostic factor for OS (B vs. C; hazard ratio [HR] 0.756 [95% CI 0.546–1.046]). Consistent treatment benefit was observed for ramucirumab versus placebo across BCLC stages. Median OS for ramucirumab versus placebo was 13.7 versus 8.2 months; HR (95%): 0.43 (0.23–0.83) and 7.7 versus 4.8 months; HR (95%): 0.72 (0.59–0.89) for BCLC stage B and C, respectively. Adverse events (AEs) were consistent with observations from both studies; hypertension was the most frequent grade ≥3 AE. Liver function was preserved throughout the study and similar between treatment arms in both BCLC stages. <b><i>Conclusions:</i></b> Ramucirumab provided a better survival benefit irrespective of BCLC stage and was well tolerated without compromising liver function during treatment.

title: Complex lying leads to more memory impairments in daily life

description: Previous studies demonstrated that lying could undermine memory, and the memory-undermining effects could be modulated by the cognitive resources required to tell the lie. We extended the investigation of the memory-undermining effect by using a daily-life paradigm in which participants were highly involved in a mock shopping task. Participants were randomly assigned to either the truth-telling, simple lying or complex lying condition. After finishing the shopping task, participants were told that two people wanted to know about their shopping lists and would ask them some questions in an interview. During the interview, participants in the truth-telling group were asked to respond honestly, those in the simple lying group were needed to give negative responses to all questions, and those in the complex lying group were required to respond deceptively. The item memory test, source memory test and destination memory test were given orderly 48 hours after the interview. We found that participants in the lying groups forgot the lies they told in the interview, and those in the complex lying group mistakenly believed they had lied about something. Moreover, the complex lying group retained fewer memories about the person they lied to. In addition, participants in the complex lying group had more nonbelieved memories than those in the truth-telling group. We conclude that more cognitive resources consumed in lying could result in more memory impairments in daily life.

title: Chemical composition of tellurium oxides thin films deposited by magnetron sputtering method

description: Thin films were prepared by radio frequency reactive magnetron sputtering technique. Metallic Te target was sputtered for about 45 min in argon-oxygen atmosphere what resulted in 300 nm film thickness deposition. The pressure in the chamber was below 0.2 Pa and substrate was heated at 200 °C. The distance between sputtered target and the Corning 1737 glass substrate was about 10 cm. Chemical composition of prepared samples was analyzed by X-ray photoemission spectroscopy method (XPS). The XPS measurement was performed at room temperature under ultra-high vacuum conditions, at pressures below 1.1 × 10−6 Pa by Omicron NanoScience equipment. Data analysis was performed with the CASA XPS software package using a Shirley background subtraction and least-square GaussianLorentzian – GL(30) curve fitting algorithm. The spectra obtained were calibrated to give a binding energy of 285.00 eV for C 1s. In this data set results of XPS investigations of thin films deposired under variuos Ar-O ratio are presented.

title: List of public benefit organizations that in 2020 received 1% of the tax due for 2019

description: The possibility of transferring 1% of personal income tax was introduced by the Act on Public Benefit and Volunteer Work in 2003, and specific provisions specifying who and how can transfer 1% of tax are included in the Personal Income Tax Act. In order to be able to accept 1% of income tax, first of all, the organization (or other authorized entity) must have the status of a public benefit organization (PBO), granted by a court. However, the status of PBO alone is not enough. Not all PBOs can take advantage of the privilege of receiving 1%, as it depends on meeting additional requirements for both newly acquired organizations and PBOs that have had this status for several years. This dataset contains information about the list of entities that obtained 1 provent of income tax from 2019 tax revenues in 2020.
