description: A polymer chain pinned in space exerts a fluctuating force on the pin point in thermal equilibrium. The average of such fluctuating force is well understood from statistical mechanics as an entropic force, but little is known about the underlying force distribution. Here, we introduce two phase space sampling methods that can produce the equilibrium distribution of instantaneous forces exerted by a terminally pinned polymer. In these methods, both the positions and momenta of mass points representing a freely jointed chain are perturbed in accordance with the spatial constraints and the Boltzmann distribution of total energy. The constraint force for each conformation and momentum is calculated using Lagrangian dynamics. Using terminally pinned chains in space and on a surface, we show that the force distribution is highly asymmetric with both tensile and compressive forces. Most importantly, the mean of the distribution, which is equal to the entropic force, is not the most probable force even for long chains. Our work provides insights into the mechanistic origin of entropic forces, and an efficient computational tool for unbiased sampling of the phase space of a constrained system.

description: Acute and chronic graft versus host disease (GVHD) are serious complications of allogeneic hematopoietic cell transplantation (HCT). The complex pathophysiology of these disease processes is associated with immune system activation, the release of cytokines and chemokines, and alterations in cell populations. The blood levels of specific protein and cellular levels in patients with GVHD have correlated with the development, diagnosis, and prognosis of GVHD. Here we review the most promising biomarkers for acute and chronic GVHD with clinical relevance. The utility of GVHD biomarkers in clinical care of allogeneic HCT recipients needs to be proven through clinical trials, and potential approaches to trial design are discussed.

description: An analysis method is proposed to study the forward-backward (FB) multiplicity fluctuation in high-energy nuclear collisions, built on the earlier work of Bzdak and Teaney. The method allows the decomposition of the centrality dependence of average multiplicity from the dynamical event-by-event (EbyE) fluctuation of multiplicity in pseudorapidity. Application of the method to AMPT and HIJING models shows that the long-range component of the FB correlation is captured by a few longitudinal harmonics, with the first component driven by the asymmetry in the number of participating nucleons in the two colliding nuclei. The higher-order longitudinal harmonics are found to be strongly damped in AMPT compare to HIJING, due to weaker short-range correlations as well as the final-state effects present in the AMPT model. Two-particle pseudorapidity correlation reveals interesting charge-dependent short-range structures that are absent in HIJING model. The proposed method opens an avenue to elucidate the particle production mechanism and early time dynamics in heavy-ion collisions. Future analysis directions and prospects of using the pseudorapidity correlation function to understand the centrality bias in $p$+$p$, $p$+A and A+A collisions are discussed.

description: The fast rates of magnetic reconnection found in both nature and experiments are important to understand theoretically. Recently, it was demonstrated that two-fluid magnetic reconnection remains fast in the strong guide field regime, regardless of the presence of fast-dispersive waves. This conclusion is in agreement with recent results from kinetic simulations, and is in contradiction to the findings in an earlier two-fluid study, where it was suggested that fast-dispersive waves are necessary for fast reconnection. In this paper, we give a more detailed derivation of the analytic model presented in a recent letter, and present additional simulation results to support the conclusions that the magnetic reconnection rate in this regime is independent of both collisional dissipation and system-size. In particular, we present a detailed comparison between fluid and kinetic simulations, finding good agreement in both the reconnection rate and overall length of the current layer. Finally, we revisit the earlier two-fluid study, which arrived at different conclusions, and suggest an alternative interpretation for the numerical results presented therein.

description: Theoretical modeling of nucleus-nucleus collision often is based on the nucleus-nucleus potential. One of the advanced methods for constructing this potential is the semi-microscopical double-folding model with the M3Y-Paris NN-forces. Proton and neutron densities are significant ingredient of this model. Correct nucleon density (ND) must reproduce experimental nuclear charge density (NCD). We consider several versions of NDs available in the literature and construct our own approximation for the ND of even-even spherical nuclei 12C, 16O, 40Ca which is abbreviated as FE-density (Fermi+exponential). We carefully compare the NCDs resulting from different versions of NDs with the experimental NCSs. After finding the nucleus-nucleus potential using the double-folding model with the density dependent M3Y-Paris NN-forces and FE densities we evaluate the above-barrier fusion cross sections for five reactions, 12C+12C, 12C+16O, 16O+16O, 16O+40Ca, and 40Ca+40Ca, where the experimental data are available. The cross sections are calculated using two approaches: a) the barrier penetration model and b) the Trajectory Model with surface friction (TM). To find the transmission coefficients for TM, the Langevin equations are employed. For all considered reactions, our TM typically reproduces the above-barrier experimental cross sections within 10-15%. The only adjustable parameter of the model, the optimal friction strength K_Rm, was found to be about 90 zs/GeV for light reactions 12C+12C, 12C+16O, 16O+16O and about 15 zs/GeV for heavier reactions 16O+40Ca and 40Ca+40Ca. The latter findings are in reasonable agreement with the systematics found earlier. Thus, the FE-recipe allows reproducing simultaneously with good accuracy both the charge nucleon density and the above-barrier fusion cross sections for five reactions involving 12C, 16O, 40Ca nuclei.

description: Large spin systems can exhibit unconventional types of magnetic ordering different from the ferromagnetic or Néel-like antiferromagnetic order commonly found in spin 1/2 systems. Spin-nematic phases, for instance, do not break time-reversal invariance and their magnetic order parameter is characterized by a second rank tensor with the symmetry of an ellipsoid. Here we show direct experimental evidence for spin-nematic ordering in a spin-1 Bose-Einstein condensate of sodium atoms with antiferromagnetic interactions. In a mean field description this order is enforced by locking the relative phase between spin components. We reveal this mechanism by studying the spin noise after a spin rotation, which is shown to contain information hidden when looking only at averages. The method should be applicable to high spin systems in order to reveal complex magnetic phases.

description: The medical image filter software and its graphical user interface (GUI) are presented in this work. This software reduces noise based on the Discrete Wavelet Transform (DWT). It works in the MATLAB environment and uses functions defined in WAVELET TOOLBOXES. Different noise types and models are available in relation to different medical modalities of imaging. The software can perform non-linear or adaptive filtering with global or penalty thresholds in horizontal, vertical and diagonal directions. The GUI also suggests interactive options for selecting the type of wavelet function and the level of decomposition. The presented GUI is also suitable for engineering training to study this wavelet application. Some experimental results obtained by computer simulation in the MATLAB environment are presented.

description: Inference of causality is central in nonlinear time series analysis and science in general. A popular approach to infer causality between two processes is to measure the information flow between them in terms of transfer entropy. Using dynamics of coupled oscillator networks, we show that although transfer entropy can successfully detect information flow in two processes, it often results in erroneous identification of network connections under the presence of indirect interactions, dominance of neighbors, or anticipatory couplings. Such effects are found to be profound for time-dependent networks. To overcome these limitations, we develop a measure called causation entropy and show that its application can lead to reliable identification of true couplings.

description: Using standard mathematical methods for asymptotic series and the large-$β_0$ approximation, we define a Minimum Distance between the Fixed-Order perturbative series and the Contour-Improved perturbative series in the strong coupling $α_s$ for finite-energy sum rules as applied to hadronic $τ$ decays. This distance is similar, but not identical, to the Asymptotic Separation of Hoang and Regner, which is defined in terms of the difference of the two series after Borel resummation. Our results confirm a nonzero nonperturbative result in $α_s$ for this Minimum Distance as a measure of the intrinsic difference between the two series, as well as a conflict with the Operator Product Expansion for Contour-Improved Perturbation Theory.

description: Due to a large discrepancy between theory and experiment, the electronic character of crystalline boron carbide B$_{13}$C$_{2}$ has been a controversial topic in the field of icosahedral boron-rich solids. We demonstrate that this discrepancy is removed when configurational disorder is accurately considered in the theoretical calculations. We find that while ordered ground state B$_{13}$C$_{2}$ is metallic, configurationally disordered B$_{13}$C$_{2}$, modeled with a superatom-special quasirandom structure method, goes through a metal to non-metal transition as the degree of disorder is increased with increasing temperature. Specifically, one of the chain-end carbon atoms in the CBC chains substitutes a neighboring equatorial boron atom in a B$_{12}$ icosahedron bonded to it, giving rise to a B$_{11}$C$^{e}$(BBC) unit. The atomic configuration of the substitutionally disordered B$_{13}$C$_{2}$ thus tends to be dominated by a mixture between B$_{12}$(CBC) and B$_{11}$C$^{e}$(BBC). Due to splitting of valence states in B$_{11}$C$^{e}$(BBC), the electron deficiency in B$_{12}$(CBC) is gradually compensated.

description: It can be argued (see Madsen & Thomsen, this volume) that people who share the same mother tongue may nevertheless “speak diffeent languages” in the sense that they will use fundamentally different vocabularies when dealing with otherwise similar fragments of extra-linguistic reality because they address them for different purposes and on the background of different sorts of knowledge. It seems relevant to ask, therefore, if the reverse may also be true. Will people with different mother tongues “speak the same language” when they deal with similar aspects of reality for similar purposes and draw on similar sorts of knowledge – be it stamp collection, yoga or water engineering? The words are bound to look and sound quite different, of course, but does that pose any serious challenges to mutual understanding if they can still replace each other in a 1:1 fashion (say, with the help of Google Translate)? To contribute to this discussion, the present article presents selected results from a comparative investigation of Danish and Russian conceptual structures and terminology in the field of public water supply systems, a domain which displays many similarities throughout the industrialized world. The findings indicate that, at least if we take a functional rather than, say, an administrative or commercial viewpoint, the terms are as good as fully compatible in terms of what is put into words, and according to which criteria. However, they display profound and seemingly systematic differences as to how the expression-units have been formed. Moreover, the latter differences seem to be consistent with Durst-Andersen’s (2011a; 2011b) description of Danish as a hearer-oriented language and Russian as a reality-oriented language. The implications of this for the idea of linguistic world-views and for the communication of professionals across national and linguistic borders are discussed.

description: "AI as a Service" (AIaaS) is a rapidly growing market, offering various plug-and-play AI services and tools. AIaaS enables its customers (users) - who may lack the expertise, data, and/or resources to develop their own systems - to easily build and integrate AI capabilities into their applications. Yet, it is known that AI systems can encapsulate biases and inequalities that can have societal impact. This paper argues that the context-sensitive nature of fairness is often incompatible with AIaaS' 'one-size-fits-all' approach, leading to issues and tensions. Specifically, we review and systematise the AIaaS space by proposing a taxonomy of AI services based on the levels of autonomy afforded to the user. We then critically examine the different categories of AIaaS, outlining how these services can lead to biases or be otherwise harmful in the context of end-user applications. In doing so, we seek to draw research attention to the challenges of this emerging area.

description: The maximum tolerated dose of palifermin, a keratinocyte growth factor, in children is not known, and its pharmacokinetics in this population has not been well studied. This is a phase I study of palifermin was designed to evaluate its tolerability at doses of 40, 60, and 90 μg/kg/day in children age 2–18 years of age, receiving a myeloablative preparative regimen for allogeneic hematopoietic stem cell transplantation (HSCT). In each cohort, palifermin was given for 3 consecutive days before the preparative regimen and for 3 days after the stem cell infusion. Twelve patients were enrolled. Palifermin 90 μg/kg/day was tolerated in 6 patients without dose-limiting toxicity. All patients had at least 1 adverse event, mostly National Cancer Institute grade 1 or 2 severity. Skin rash, grade 2 or lower, was the most common adverse event, seen in 67% of patients. Only 3 patients (25%) had mucositis. The area under the concentration–time curve increased proportionally to the dose, and approximately 97% of palifermin exposure occurred in the first 24 hours after administration. Palifermin clearance increased linearly with body weight, supporting dosing by body weight. The mean clearance was 1893 mL/hour/kg, and it did not change significantly between administration of the first and last doses (P =.80). The mean elimination half-life was 4.6 hours. Our data show that palifermin was tolerated at a dose of 90 μg/kg/day, and exhibits linear pharmacokinetics in children undergoing allogeneic HSCT.

description: Recently, the first JWST measurement of thermal emission from a rocky exoplanet was reported. The inferred dayside brightness temperature of TRAPPIST-1 b at 15 $μ$m is consistent with the planet having no atmosphere and therefore no mechanism by which to circulate heat to its nightside. In this Letter, we compare the measured secondary eclipse depth of TRAPPIST-1 b to predictions from a suite of self-consistent radiative-convective equilibrium models in order to quantify the maximum atmospheric thickness consistent with the observation. We find that plausible atmospheres (i.e., those that contain at least 100 ppm CO$_2$) with surface pressures greater than 0.01 bar (0.1 bar) are ruled out at 1$σ$ (3$σ$), regardless of the choice of background atmosphere. Thicker atmospheres of up to 10 bar (100 bar) at 1$σ$ (3$σ$) are only allowed if the atmosphere lacks any strong absorbers across the mid-IR wavelength range, a scenario that we deem unlikely. We additionally model the emission spectra for bare-rock planets of various compositions. We find that a variety of silicate surfaces match the measured eclipse depth to within 1$σ$, and the best-fit grey albedo is $0.02 \pm 0.11$. We conclude that planned secondary eclipse observations at 12.8 $μ$m will serve to validate the high observed brightness temperature of TRAPPIST-1 b, but are unlikely to further distinguish among the consistent atmospheric and bare-rock scenarios.

Year: 2016

description: This paper presents a number of findings concerning impoliteness within the workplace email of Chinese users of English. Particular interest was given to the exploration of the relationship between specific speech acts and the occurrence of impoliteness and non-politeness; what impolite devices were used in frontline business communication; what are the circumstances, patterns and functions of impoliteness in workplace email? Findings illustrate that message enforcers were the most common impoliteness device used, generally being utilized to make a demand, emphasize a position and place blame. In terms of giving rise to potential impoliteness the assertive speech act was the most hazardous. In order to maintain authenticity the examples used are reproduced exactly as they occurred in the data set, in places substantial deviations from the conventions of English grammar and spelling are to be found. Pedagogical implications are discussed in the conclusion.

The introduction of this matrix, however, results in serious problems and imposes fundamental limitations to the quality of the ranking vectors. In this work, building on the recently proposed NCDawareRank framework, we exploit the decomposition of the underlying space into blocks, and we derive easy to check necessary and sufficient conditions for random surfing without teleportation.

Professional discourse and professional identities at cross-purposes: Designer or entrepreneur?
Creators: name: Norlyk, Birgitte
Publisher: name: Globe: A Journal of Language, Culture and Communication
Year: 2016

description: What happens when designer dreams meet business reality? This paper illustrates how a group of professional designers experienced emotional tensions and conflicts of personal and professional identity during an eight-week voluntary course on business and entrepreneurship for the creative professions. The designers' discourse, which revolved around ideals of commitment towards artistic integrity, aesthetics and design clashed with the hard core discourse of business which highlighted practical concerns relating especially to market considerations and the necessity of adapting designs to existing means of production. Intellectually, the designers agreed on the need to develop business skills to improve their financial situation and enhance their employability. Emotionally, however, their choice of discourse, metaphors and framing strategies reflected a series of professional and personal conflicts and struggles of identity. The study illustrates the oscillating nature of designers' identity negotiations between business and design but offers no one-size-fits-all solution to business training for the creative professions. The data reflect that identity negotiations do not take the form of a liniar process in which logic, material concerns and business sense will eventually prevail. To facilitate the potential incorporation of business thinking into the professional identity of designers, the data indicate that business related training targeting the creative professions would benefit from paying increased attention to the influence of professional discourse and sensemaking patterns on the construction of personal and professional selves.

The IL-17 Differentiation Pathway and Its Role in Transplant Outcome

Year: 2012

description: The limitations of allogeneic transplantation are graft-versus-host disease (both acute and chronic), infection, and relapse. Acute GVHD has traditionally been thought of as a Th1-mediated disease with inflammatory cytokines (eg, inteferon [IFN]-γ and tumor necrosis factor [TNF]) and cellular cytolysis mediating apoptotic target tissue damage in skin, gut, and liver. Chronic GVHD has not fit neatly into either Th1 or Th2 (eg, IL-4, IL-13) paradigms. Increasingly, the Th17 pathway of differentiation has been shown to play important roles in acute and chronic GVHD (aGVHD, cGVHD), particularly in relation to skin and lung disease. Here we discuss the IL-17 pathway of T cell differentiation and the accumulating evidence suggesting it represents an important new target for the control of deleterious alloimmune responses.

We present the spectral templates for identification and redshift estimation of quasars in the DESI Year 1 data release. The quasar templates are comprised of two quasar eigenspectra sets, trained on spectra from the Sloan Digital Sky Survey. The sets are specialized to reconstruct quasar spectral variation observed over separate yet overlapping redshift ranges and, together, are capable of identifying DESI quasars from $0.05 < z <7.0$. The new quasar templates show significant improvement over the previous DESI quasar templates regarding catastrophic failure rates, redshift precision and accuracy, quasar completeness, and the contamination fraction in the final quasar sample.

description: Patient-reported outcomes (PROs), including symptoms and health-related quality of life (HRQOL), provide a patient-centered description of hematopoietic cell transplantation (HCT)-related toxicity. These data characterize the patient experience after HCT and may have prognostic usefulness for long-term outcomes after HCT. We conducted a study of 32 patients after HCT (10 autologous HCT recipients, 11 full-intensity conditioning allogeneic HCT recipients, and 11 reduced-intensity conditioning allogeneic HCT recipients) to determine the feasibility of weekly electronic PRO collection from HCT until day (D) + 100. We used questions from the PRO version of the Common Terminology Criteria for Adverse Events to capture symptoms, and the Patient-Reported Outcomes Measurement Information System Global Health scale to measure physical and mental HRQOL. The vast majority (94%) of patients used the electronic PRO system, with only 6% opting for paper-and-pencil only. The median weekly percentage of participants who completed the surveys was 100% in all cohorts through hospital discharge, and remained 100% for the autologous HCT and reduced-intensity allogeneic HCT cohorts through D+100. Patients were satisfied with the electronic system, giving high marks for readability, comfort, and questionnaire length. Symptom severity varied by absolute level and type of symptom across the 3 cohorts, with the full-intensity allogeneic HCT cohort exhibiting the greatest median overall symptom severity, peaking at D+7. Median physical health HRQOL scores decreased with time in the 3 cohorts, and HRQOL was generally correlated with overall symptom severity. Our results demonstrate the feasibility of frequent electronic PROs in the early post-HCT period. Future studies in larger populations to explore predictive models using frequent PRO data for outcomes, including long-term HRQOL and survival, are warranted.

description: Let $E$ be a Banach space and $A$ be a commutative Banach algebra with identity. Let ${P}(E, A)$ be the space of $A$-valued polynomials on $E$ generated by bounded linear operators (an $n$-homogenous polynomial in ${P}(E,A)$ is of the form $P=\sum_{i=1}^\infty T^n_i$, where $T_i:E\to A$ ($1\leq i <\infty$) are bounded linear operators and $\sum_{i=1}^\infty \|T_i\|^n < \infty$). For a compact set $K$ in $E$, we let ${P}(K, A)$ be the closure in $C(K,A)$ of the restrictions $P|_K$ of polynomials $P$ in ${P}(E,A)$. It is proved that ${P}(K, A)$ is an $A$-valued uniform algebra and that, under certain conditions, it is isometrically isomorphic to the injective tensor product $\mathcal{P}_N(K)\hat\otimes_εA$, where $\mathcal{P}_N(K)$ is the uniform algebra on $K$ generated by nuclear scalar-valued polynomials. The character space of ${P}(K, A)$ is then identified with $\hat{K}_N\times \mathfrak{M}(A)$, where $\hat K_N$ is the nuclear polynomially convex hull of $K$ in $E$, and $\mathfrak{M}(A)$ is the character space of $A$.

description: Organic inorganic hybrid perovskites (OIHPs) have appealing optoelectronic properties. As sample preparation is relatively straightforward, there are opportunities to investigate novel compositions and structures. This thesis concerns the synthesis, structure and optoelectrical properties of OIHPs with azetidinium as an A-site cation. Azetidinium [(CH₂)₃NH₂⁺, Az] is a four-member ring ammonium, and its size is calculated to be promising as an A-cation for OIHPs. A stable 6H hexagonal perovskite AzPbBr₃ was synthesised and analysed, and its bandgap was determined to be 2.81 eV. On cooling, AzPbBr₃ undergoes a symmetry lowering distortion which was identified by variable temperature PXRD and dielectric spectroscopy. An anisotropic change in lattice parameters on cooling marked a phase transition likely driven by the Pb⋯Pb repulsion in the face sharing octahedra. Compositional and structural analyses were performed on precipitation synthesised and mechanosynthesised OIHPs Az₁₋ₓFAₓPbBr₃ and Az₁₋ₓMAₓPbBr₃ (0 ≤ x ≤ 1). For samples obtained from precipitation synthesis, the actual FA% or MA% in the precipitate was found to be less than the nominal composition in the reaction solution. No such mismatch was found for mechanosynthesised samples. PXRD indicated partial solid solution formation for Az-rich and MA- or FA-rich compositions, separated by an intermediate two-phase region. The result suggests the extent of the solid solution of halide perovskites is dependent only on the average A-cation size; the size mismatch is less of an influence. This is in contrast to solid solution formation observed in oxide perovskites. A tuneable bandgap was achieved ranging from 2.00 eV (AzPbI₃) to 3.41 eV (AzPbCl₃) for the mixed halide perovskite AzPbBr₃₋ₓXₓ (X = Cl or I, 0 ≤ x ≤ 3). The structural analyses revealed a complete 6H solid solution for AzPbBr₃₋ₓClₓ in comparison to the structural progression from 6H, 4H to 9R polytypes, when varying the halide composition from Br (x = 0) to I (x = 3) in AzPbBr₃₋ₓIₓ. A linear variation in unit cell volume as a function of anion average radius was observed not only within the solid solution of each polytype (following Vegard’s law) but continuously across all three polytypes. Preliminary results on the synthesis and structural analysis indicate that Az₂PbBr₄ adopts the 𝘯 = 1 Ruddlesden-Popper structure while azetidinium bismuth bromide has a 1D chain structure. Detailed structural and optical analysis are planned in future projects.

description: Studies show that engaging patients in exercise and/or stress management techniques during hematopoietic cell transplantation (HCT) improves quality of life. The Blood and Marrow Transplant Clinical Trials Network tested the efficacy of training patients to engage in self-directed exercise and stress management during their HCTs. The study randomized 711 patients at 21 centers to receive one of four training interventions before HCT: a self-directed exercise program, a self-administered stress management program, both or neither. Participants completed self-reported assessments at enrollment and up to 180 days after transplant. Randomization was stratified by center and transplant type. There were no differences in the primary endpoints of the physical (PCS) and mental (MCS) component scales of the SF36 at day 100 among the groups based on an intention-to-treat analysis. There were no differences observed in overall survival, hospital days through day 100 post-HCT, or in other patient-reported outcomes, including treatment-related distress, sleep quality, pain, and nausea. Patient randomized to training in stress management reported more use of those techniques; patients randomized to training in exercise did not report more physical activity. Although other studies have reported efficacy of more intensive interventions, brief training in an easy-to-disseminate format for either self-directed exercise or stress management was not effective in our trial.

description: Extending the knowledge about the properties of solar cycles into the past is essential for understanding the solar dynamo. This paper aims at estimating areas of sunspots observed by Schwabe in 1825-1867 and at calculating the tilt angles of sunspot groups. The sunspot sizes in Schwabe's drawings are not to scale and need to be converted into physical sunspot areas. We employed a statistical approach assuming that the area distribution of sunspots was the same in the 19th century as it was in the 20th century. Umbral areas for about 130,000 sunspots observed by Schwabe were obtained, as well as the tilt angles of sunspot groups assuming them to be bipolar. There is, of course, no polarity information in the observations. The annually averaged sunspot areas correlate reasonably with sunspot number. We derived an average tilt angle by attempting to exclude unipolar groups with a minimum separation of the two alleged polarities and an outlier rejection method which follows the evolution of each group and detects the moment it turns unipolar at its decay. As a result, the tilt angles, although displaying considerable scatter, place the leading polarity on average 5.85+-0.25 closer to the equator, in good agreement with tilt angles obtained from 20th-century data sets. Sources of uncertainties in the tilt angle determination are discussed and need to be addressed whenever different data sets are combined. The sunspot area and tilt angle data are provided online.

description: The environment of gamma-ray burst (GRB) has an important influence on the evolution of jet dynamics and of its afterglow. Here we investigate the afterglow polarizations in a stratified medium with the equal arrival time surface (EATS) effect. Polarizations of multi-band afterglows are predicted. The effects of the parameters of the stratified medium on the afterglow polarizations are also investigated. We found the influences of the EATS effect on the afterglow polarizations become important for off-axis detections and PD bumps move to later times with the EATS effect. Even the magnetic field configurations, jet structure and observational angles are fixed, polarization properties of the jet emission could still evolve. Here, we assume a large-scale ordered magnetic field in the reverse-shock region and a two-dimensional random field in the forward-shock region. Then PD evolution is mainly determined by the evolution of $f_{32}$ parameter (the flux ratio between the reverse-shock region and forward-shock region) at early stage and by the evolution of the bulk Lorentz factor $γ$ at late stage. Through the influences on the $f_{32}$ or $γ$, the observational energy band, observational angles, and the parameters of the stratified medium will finally affect the afterglow polarizations.
