description: We study the mobility and the diffusion coefficient of an inertial tracer advected by a two-dimensional incompressible laminar flow, in the presence of thermal noise and under the action of an external force. We show, with extensive numerical simulations, that the force-velocity relation for the tracer, in the nonlinear regime, displays complex and rich behaviors, including negative differential and absolute mobility. These effects rely upon a subtle coupling between inertia and applied force which induce the tracer to persist in particular regions of phase space with a velocity opposite to the force. The relevance of this coupling is revisited in the framework of non-equilibrium response theory, applying a generalized Einstein relation to our system. The possibility of experimental observation of these results is also discussed.

Creators: name: Gebretsadik, Simret
Publisher: name: African Journal of Leadership and Development
Year: 2020

description: For the past two decades, Ethiopia was engaged in changing her public service sector culture from bureaucratic to market type. The reform program was introduced in to all Ethiopian public service organizations simultaneously and using the same change tools. However, except in few organizations, the reform did not result in organizational culture change. DARA is one of the few organizations known for their reform success and LDMB is one of the many organizations identified with unfruitful reform efforts. The objective of this study was to investigate influence of reform management on organizational culture change in the cases of DARA and LDMB. The research methodology of the study was based on a pragmatic worldview followed by convergent parallel mixed methods approach. Quantitative data were collected from 130 leaders and 435 employees of DARA and LDMB. Besides,qualitative data were gathered via interviews and document review. Data analysis was done using PLS-SEM, Mann-Whitney U test, Binomial logistic regression, percentages and narration. Findings revealed that, eventhough Kotters’ change management model has mishandled organizational culture, its strict application has resulted in culture change at DARA. Factors that have contributed to DARA’s reformare success are availability of resources, leadership’s competence in change management, existence of feltneed for change and prevalence of leadership autonomy. Therefore, the study concluded that the way reform is managed in a certain organization determines the level of organizational culture change to be obtained in the same. To that end, Kotter’s change management model needs to be modified so that it could enable organizations manage organizational culture change effectively.

description: This paper presents algorithms for identifying and reducing a dedicated set of controllable transition rates of a state-labelled continuous-time Markov chain model. The purpose of the reduction is to make states to satisfy a given requirement, specified as a CSL upper time-bounded Until formula. We distinguish two different cases, depending on the type of probability bound. A natural partitioning of the state space allows us to develop possible solutions, leading to simple algorithms for both cases.

title: Flavors of biotin ligases: From research tools towards biopharmaceutical applications
Creators: name: Bitsch, Sebastian Harald
Publisher: name: UNSPECIFIED
Year: 2023

description: Biotin ligases are enzymes commonly attaching biotin to biotin-dependent enzymes, which are fundamental for essential metabolic pathways like gluconeogenesis or fatty acids synthesis. However, in times of protein engineering and genome editing those enzymes can be utilized in versatile ways. In this work biotin ligases were deployed in different fields of research starting with a tool for fundamental understanding of cell biology and culminating in biopharmaceutical approaches. First, a novel enzyme called ultraID applicable for protein-protein interaction studies was engineered by directed evolution. This undertaking was carried out by error-prone PCR mutagenesis and yeast surface display in combination with fluorescence activated cell sorting. While based on a biotin ligase derived from Aquifex aeolicus the novel enzyme exhibited a massively improved catalytic turnover, which was tracked back to one single mutation in the active site. To date, ultraID is one of the smallest and most efficient enzymes for the proximity-dependent biotin identification method. Second, screening of the randomized biotin ligase library was conducted towards a modified biotin substrate. Hereby, a propargyl functionalized biotin derivative was examined for enzyme turnover. Even tough different yeast surface presentation and assay strategies were analyzed a propargyl biotin using enzymes was not identified. Third, fundamental experiments for the generation of an antibody-drug conjugate by biotin ligases were performed. A biotin ligase derived from Pyrococcus horikoshii was exploited to conjugate propargyl biotin and desthiobiotin azide to the therapeutic antibody trastuzumab, which was equipped with a biotin acceptor domain. It was successfully demonstrated that chemoenzymatic modification was feasible by conjugating a fluorophore to the antibody. However, the usage of desthiobiotin azide as a substrate renders the biotin ligase unspecific and consequently, optimizations must be done in future approaches. In parallel an antibody-drug conjugate was generated by a different approach. Lipoate-protein ligase A derived from Escherichia coli was used to conjugate a click chemistry moiety to a tagged trastuzumab. Subsequent attachment of a Monomethyl auristatin E toxin led to the generation of an antibody-drug conjugate with potency in the picomolar range. Additionally, it was shown that the applied conjugation strategy had no impact on the antibodies affinity and enzymatic conjugation was complete within a few minutes. Last, identification of internalizing single-chain variable fragments out of systemic lupus erythematosus phage display library was executed. Hereby different enrichment strategies were examined involving incubation on mammalian cells and biotinylation of phages upon successful cell penetration. Ultimately, discovery of an internalizing binder was not achieved but crucial knowledge on phage display-based enrichment of cell penetrating binders was obtained.

description: Annually, over 18 million disease cases and half a million deaths worldwide are estimated to be caused by Group A Streptococcus. ScpA (or C5a peptidase) is a well characterised member of the cell enveleope protease family, which possess a S8 subtilisin-like catalytic domain and a shared multi-domain architecture. ScpA cleaves complement factors C5a and C3a, impairing the function of these critical anaphylatoxins and disrupts complement-mediated innate immunity. Although the high resolution structure of ScpA is known, the details of how it recognises its substrate are only just emerging. Previous studies have identified a distant exosite on the 2nd fibronectin domain that plays an important role in recruitment via an interaction with the substrate core. Here, using a combination of solution NMR spectroscopy, mutagenesis with functional assays and computational approaches we identify a second exosite within the protease-associated (PA) domain. We propose a model in which the PA domain assists optimal delivery of the substrate’s C terminus to the active site for cleavage.

description: The detection of organic molecules with increasing complexity and potential biological relevance is opening the possibility to understand the formation of the building blocks of life in the interstellar medium. One of the families of molecules with astrobiological interest are the esters, whose simplest member, methyl formate, is rather abundant in star-forming regions. The next step in the chemical complexity of esters is ethyl formate, C$_2$H$_5$OCHO. Only two detections of this species have been reported so far, which strongly limits our understanding of how complex molecules are formed in the interstellar medium. We have searched for ethyl formate towards the W51 e2 hot molecular core, one of the most chemically rich sources in the Galaxy and one of the most promising regions to study prebiotic chemistry, especially after the recent discovery of the P$-$O bond, key in the formation of DNA. We have analyzed a spectral line survey towards the W51 e2 hot molecular core, which covers 44 GHz in the 1, 2 and 3 mm bands, carried out with the IRAM 30m telescope. We report the detection of the trans and gauche conformers of ethyl formate. A Local Thermodynamic Equilibrium analysis indicates that the excitation temperature is 78$\pm$10 K and that the two conformers have similar source-averaged column densities of (2.0$\pm$0.3)$\times$10$^{16}$ cm$^{-2}$ and an abundance of $\sim$10$^{-8}$. We compare the observed molecular abundances of ethyl formate with different competing chemical models based on grain surface and gas-phase chemistry. We propose that grain-surface chemistry may have a dominant role in the formation of ethyl formate (and other complex organic molecules) in hot molecular cores, rather than reactions in the gas phase.

description: OS compromise is one of the most serious computer security problems today, but still not being resolved. Although people proposed different kinds of methods, they could not be accepted by most users who are non-expert due to the lack of compatibility and usability. In this paper, we introduce a kind of new mandatory access control model, named CUMAC, that aims to achieve good-enough security, high compatibility and usability. It has two novel features. One is access control based on tracing potential intrusion that can reduce false negatives and facilitate security configuration, in order to improve both compatibility and usability; the other is automatically figuring out all of the compatibility exceptions that usually incurs incompatible problems. The experiments performed on the prototype show that CUMAC can defense attacks from network, mobile disk and local untrustable users while keeping good compatibility and usability.

description: The goal of this deliverable is to create an open data specification for the mutual recognition of skills and experiences held by makers, by establishing an understanding of vocabulary and a shared taxonomy of skills and experiences, as well as a framework for the verification of this knowledge. By analysing existing credential verification and learning data systems in digital fabrication and educational settings and gathering data from makerspace leaders around the world, we were able to create a preliminary data standard which can be used as part of a Knowledge Verification Framework for the recognition of an individual maker’s identity and credentials. The People and Skills Specification (PSS) provides a structure for verifying the skills and experiences that are needed to make a specific thing, and, when used in conjunction with a Knowledge Verification Framework, the PSS gives individual makers the capability to signal their experiences and skills to potential employers, collaborators, and policy makers around the world.

description: Internal communication has an important part to play in the effectiveness of change initiatives. This study explored Practices of Communication to Manage Change in two woredas health offices and health centers. Managers and employees were a target population to this study. The study sought to answer types of communication strategies and factors affecting the effectiveness of communication. A mixed approach was used for gathering the data required to answer the research questions. Survey was administered to 154 employees. Two focus groups discussions were undertaken with two woredas 16 board members of the health centers. Five managers from sub city and two woredas health offices were interviewed. The data gathered from these three methods were analyzed utilizing frequency distribution and also percentage for categorical variables. Qualitative data were grouped and interpreted. Analysis revealed that the major communication strategies including communicating objectives of the change, providing training about directives of the changes and introducing success of the change were employed successfully. However, lack of trust due to lack of answering for employee’s questions and introducing the effect of the change before the change took place were among the problems identified. A number of barriers to communication effectiveness including attitudinal problems and skill gap were identified. Managers within the offices should be more comprehensively briefed and trained about communication by integrating with change processes. In relation to this there must be a need to address the perceived gap between communication strategies with those employees who agreed or not perhaps initially through improved communication.

An axiomatic approach to Maxwell's equations
Creators: name: Heras, José A.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: This paper suggests an axiomatic approach to Maxwell's equations. The basis of this approach is a theorem formulated for two sets of functions localized in space and time. If each set satisfies a continuity equation then the theorem provides an integral representation for each function. A corollary of this theorem yields Maxwell's equations with magnetic monopoles. It is pointed out that the causality principle and the conservation of electric and magnetic charges are the most fundamental physical axioms underlying these equations. Another application of the corollary yields Maxwell's equations in material media. The theorem is also formulated in the Minkowski space-time and applied to obtain the covariant form of Maxwell's equations with magnetic monopoles and the covariant form of Maxwell's equations in material media. The approach makes use of the infinite-space Green function of the wave equation and is therefore suitable for an advanced course in electrodynamics.

description: A practical statistical analysis on the regional populations and GDPs of China is conducted. The result shows that the distribution of the populations and that of the GDPs obeys the shifted power law, respectively. To understand these characteristics, a generalized Langevin equation describing variation of population is proposed based on the correlation between population and GDP as well as the random fluctuations of the related factors. The equation is transformed into the Fokker-Plank equation, and the solution demonstrates a transform of population distribution from the normal Gaussian distribution to a shifted power law. It also suggests a critical point of time at which the transform occurs. The shifted power law distribution in the supercritical situation is qualitatively in accordance with the practical result. The distribution of the GDPs is derived based on the Cobb-Douglas production function, and presents a change from a shifted power law to the Gaussian distribution. This result indicates that the regional GDP distribution of our society will be the Gaussian distribution in the future. The analysis on the growth trend of economy suggests it will become a reality. These theoretical attempts may draw a historical picture of our world in the aspects of population and economy.

description:
Geologically located in the Northeast German Basin, Berlin and most parts of Brandenburg are known to be potentially suitable for deep geothermal energy usage. This source of energy is not yet well-established in the area. However, regarding Germany’s transition towards climate-friendly and regional energy solutions, the energy demand from renewables is rapidly increasing. Thus, geothermal exploration and assessing geothermal potential is significant. We assess “Heat In Place” (HIP) as quintessential part of the geothermal potential for a series of litho-stratigraphic units for Berlin and Brandenburg.

Geothermal potential is defined as considering characteristics of a specific geothermal plant and/or the geological reservoir. We concentrate on the latter geological aspects and take a 3D geological and two different 3D thermal models of Brandenburg as basis for the HIP calculations. This HIP approach corresponds to a volumetric quantification of contained energy within 16 litho-stratigraphic units, each taking variable thickness, mean temperature, porosity, density, and specific heat capacity into account. This results in a series of new geothermal potential maps derived from different thermal models: Firstly, conductive heat transport, and secondly, coupled thermal-hydraulic simulations. We aim at deepening the understanding of HIP maps for geothermal power plant site decision making by showing how the calculated heat varies between those two modelling approaches, and different parameter estimates.

description: In online social networks (OSN), users quite usually disclose sensitive information about themselves by publishing messages. At the same time, they are (in many cases) unable to properly manage the access to this sensitive information due to the following issues: i) the rigidness of the access control mechanism implemented by the OSN, and ii) many users lack of technical knowledge about data privacy and access control. To tackle these limitations, in this paper, we propose a dynamic, transparent and privacy-driven access control mechanism for textual messages published in OSNs. The notion of privacy-driven is achieved by analyzing the semantics of the messages to be published and, according to that, assessing the degree of sensitiveness of their contents. For this purpose, the proposed system relies on an automatic semantic annotation mechanism that, by using knowledge bases and linguistic tools, is able to associate a meaning to the information to be published. By means of this annotation, our mechanism automatically detects the information that is sensitive according to the privacy requirements of the publisher of data, with regard to the type of reader that may access such data. Finally, our access control mechanism automatically creates sanitized versions of the users' publications according to the type of reader that accesses them. As a result, our proposal, which can be integrated in already existing social networks, provides an automatic, seamless and content-driven protection of user publications, which are coherent with her privacy requirements and the type of readers that access them. Complementary to the system design, we also discuss the feasibility of the system by illustrating it through a real example and evaluate its accuracy and effectiveness over standard approaches.

description: Studies of vertical and interhemispheric coupling during Sudden Stratospheric Warmings (SSWs) suggest that gravity wave (GW) momentum flux divergence plays a key role in forcing the middle atmosphere, although observational validation of GW forcing is limited. We present a whole atmosphere view of zonal winds from the surface to 100 km during the January 2013 major SSW, together with observed GW momentum fluxes in the mesopause region derived from uninterrupted high-resolution meteor radar observations from an All-Sky Interferometric Meteor Radar system located at Trondheim, Norway (63.4 $^{\circ}$N, 10.5 $^{\circ}$E). Observations show GW momentum flux divergence 6 days prior to the SSW onset, producing an eastward forcing with peak values of $\sim$+145 $\pm$ 60m $s^{-1}$ $d^{-1}$. As the SSW evolves, GW forcing turns westward, reaching a minimum of $\sim$-240 $\pm$ 70 m $s^{-1}$ $d^{-1}$ $\sim$+18 days after the SSW onset. These results are discussed in light of previous studies and simulations using the Whole Atmosphere Community Climate Model with Specified Dynamics.

We then completely parametrize the class of $(2\aleph+1)$-mode pure Gaussian states that can be prepared by this type of quantum harmonic oscillator chain. This parametrization allows us to determine the steady-state entanglement properties of such quantum harmonic oscillator chains.

Using Feynman path-integral approach for the model we find corrections to conditional probability density function, output signal distribution, conditional and output signal entropies, and the channel capacity at large signal-to-noise ratio. We demonstrate that the correction to the channel capacity is positive for large signal power. Therefore, this correction increases the earlier calculated capacity for a nondispersive nonlinear optical fiber channel in the intermediate power region.

description: Cells crawling through tissues migrate inside a complex fibrous environment called the extracellular matrix (ECM), which provides signals regulating motility. Here we investigate one such well-known pathway, involving mutually antagonistic signalling molecules (small GTPases Rac and Rho) that control the protrusion and contraction of the cell edges (lamellipodia). Invasive melanoma cells were observed migrating on surfaces with topography (array of posts), coated with adhesive molecules (fibronectin, FN) by Park et al., 2016. Several distinct qualitative behaviors they observed included persistent polarity, oscillation between the cell front and back, and random dynamics. To gain insight into the link between intracellular and ECM signaling, we compared experimental observations to a sequence of mathematical models encoding distinct hypotheses. The successful model required several critical factors. (1) Competition of lamellipodia for limited pools of GTPases. (2) Protrusion / contraction of lamellipodia influence ECM signaling. (3) ECM-mediated activation of Rho. A model combining these elements explains all three cellular behaviors and correctly predicts the results of experimental perturbations. This study yields new insight into how the dynamic interactions between intracellular signaling and the cell's environment influence cell behavior.

description: The purpose of this research was to assess the capacity building supports to emerging regions: the contribution of the Ministry of Federal Affairs in the case of Afar region. The researchers used descriptive survey research, and exploratory research to assess what has been done so far, and the challenges faced while building the capacity of the region. Data were collected from both primary and secondary sources. Primary data were collected from employees in selected woredas, woreda managers, and consultants from MoFA. To select the sample respondents as a primary data source probability and non-probability sampling methods were used. The data collection tools used were questionnaire, interview, and focus group discussions. The collected data were coded, tabulated and analyzed using SPSS software. One of the major findings of the study was the capacity building practices of the region is below expectation due to individual, organizational, and leadership factors. The other important finding was the contribution of MoFA in the region is not significant and clear for the woredas supposed to get the support. The researchers recommended that the individual, institutional, and enabling environment should be enhanced and the support given by MoFA should be clear for all and it has to be executed in a planned way, monitoring, and evaluated accordingly.

description: Excerpts: This extensive bibliography includes about 350 different formal publications or easily accessible other references. All are recommended for understanding the measurement, significance and contribution of natural resource capital accumulation to the growth and development of agriculture in the United States. Irrigation, drainage and conservation assets (IDC) are the main components of natural resource capital covered. But we also include some key references on flood protection, environmental controls, energy topics, and agricultural research. Concerning organization, the 350 separate items are classed into eleven specialized lists, but only the first seven groups are true subject-matter separations. They involve: capital and investment in general, economic growth and productivity (separated for the economy as a whole versus agriculture), general aspects of land use and resource development policy, mathematical/statistical techniques and evaluation methodologies, and some representative survey studies of natural resource investment. The seventh list is for the literature useful in developing capital stocks of specialized irrigation equipment and on-farm irrigation water supply facilities, a hitherto neglected area of agricultural research.

description: The current state of the art for large-scale quantum-mechanical simulations is the planewave (PW) pseudopotential method, as implemented in codes such as VASP, ABINIT, and many others. However, since the PW method uses a global Fourier basis, with strictly uniform resolution at all points in space, it suffers from substantial inefficiencies in calculations involving atoms with localized states, such as first-row and transition-metal atoms, and requires significant nonlocal communications, which limit parallel efficiency. Real-space methods such as finite-differences and finite-elements have partially addressed both resolution and parallel-communications issues but have been plagued by one key disadvantage relative to PW: excessive number of degrees of freedom needed to achieve the required accuracies. We present a real-space partition of unity finite element (PUFE) method to solve the Kohn-Sham equations of density functional theory. In the PUFE method, we build the known atomic physics into the solution process using partition-of-unity enrichment techniques in finite element analysis. The method developed herein is completely general, applicable to metals and insulators alike, and particularly efficient for deep, localized potentials, as occur in calculations at extreme conditions of pressure and temperature. Full self-consistent Kohn-Sham calculations are presented for LiH, involving light atoms, and CeAl, involving heavy atoms with large numbers of atomic-orbital enrichments. We find that the new PUFE approach attains the required accuracies with substantially fewer degrees of freedom, typically by an order of magnitude or more, than the PW method. We compute the equation of state of LiH and show that the computed lattice constant and bulk modulus are in excellent agreement with reference PW results, while requiring an order of magnitude fewer degrees of freedom to obtain.

description: This study explores perceptions of online racial hate speech directed at Asian Americans in the United States during the COVID-19 pandemic. We examined how individuals’ enactment of resilience communication in response to that threat affected their self-reported estimates of personal health. Using a nationally representative survey (n = 1767) that oversampled Asian Americans (n = 455), we found that Asian Americans perceived the problem of online hate speech to be more severe than members of non-targeted groups. Analysis revealed a mediated pathway through which heightened perceptions of online racial hate speech were positively associated with individuals’ enactment of specific resilience processes tied to identity affirmation, which was linked to positive gains in psychological health. Results contribute to resilience theory in the context of racism and the observed relationships between resilience communication and health. We discuss how individuals in minoritized communities and allies might use resilience to combat the synergistic stressors of the COVID-19 pandemic.

description: Hospital readmission within 30 days of discharge (30-day readmission) is a high-priority quality measure and cost target. The purpose of this study was to explore the feasibility and efficacy of the Diabetes Transition of Hospital Care (DiaTOHC) Program on readmission risk in high-risk adults with diabetes. This was a non-blinded pilot randomized controlled trial (RCT) that compared usual care (UC) to DiaTOHC at a safety-net hospital. The primary outcome was all-cause 30-day readmission. Between 16 October 2017 and 30 May 2019, 93 patients were randomized. In the intention-to-treat (ITT) population, 14 (31.1%) of 45 DiaTOHC subjects and 15 (32.6%) of 46 UC subjects had a 30-day readmission, while 35.6% DiaTOHC and 39.1% UC subjects had a 30-day readmission or ED visit. The Intervention–UC cost ratio was 0.33 (0.13–0.79) 95%CI. At least 93% of subjects were satisfied with key intervention components. Among the 69 subjects with baseline HbA1c >7.0% (53 mmol/mol), 30-day readmission rates were 23.5% (DiaTOHC) and 31.4% (UC) and composite 30-day readmission/ED visit rates were 26.5% (DiaTOHC) and 40.0% (UC). In this subgroup, the Intervention–UC cost ratio was 0.21 (0.08–0.58) 95%CI. The DiaTOHC Program may be feasible and may decrease combined 30-day readmission/ED visit risk as well as healthcare costs among patients with HbA1c levels >7.0% (53 mmol/mol).

description: We present CARMA CO (J=1-0) observations and Herschel PACS spectroscopy, characterizing the outflow properties toward extremely young and deeply embedded protostars in the Orion molecular clouds. The sample comprises a subset of the Orion protostars known as the PACS Bright Red Sources (PBRS) (Stutz et al. 2013). We observed 14 PBRS with CARMA and 8 of these 14 with Herschel, acquiring full spectral scans from 55 micron to 200 micron. Outflows are detected in CO (J=1-0) from 8 of 14 PBRS, with two additional tentative detections; outflows are also detected from the outbursting protostar HOPS 223 (V2775 Ori) and the Class I protostar HOPS 68. The outflows have a range of morphologies, some are spatially compact, <10000 AU in extent, while others extend beyond the primary beam. The outflow velocities and morphologies are consistent with being dominated by intermediate inclination angles (80 deg > i > 20 deg). This confirms the interpretation of the very red 24 micron to 70 micron colors of the PBRS as a signpost of high envelope densities, with only one (possibly two) cases of the red colors resulting from edge-on inclinations. We detect high-J (J_up > 13) CO lines and/or H_2O lines from 5 of 8 PBRS and only for those with detected CO outflows. The far-infrared CO rotation temperatures of the detected PBRS are marginally colder (~230 K) than those observed for most protostars (~300 K), and only one of these 5 PBRS has detected [OI] 63 micron emission. The high envelope densities could be obscuring some [OI] emission and cause a ~20 K reduction to the CO rotation temperatures.
