description: Tumors pose a significant global economic and health burden, with conventional cancer treatments lacking tumor specificity, leading to limited efficiency and undesirable side effects. Targeted tumor therapy is imminent. Tumor cells produce lactate and hydrogen ions (H+) by Warburg effect, forming an acidic tumor microenvironment (TME), which can be employed to design targeted tumor therapy. Recently, progress in nanotechnology has led to the development of pH-responsive nanocarriers, which have gathered significant attention. Under acidic tumor conditions, they exhibit targeted accumulation within tumor sites and controlled release profiles of therapeutic reagents, enabling precise tumor therapy. This review comprehensively summarize the principles underlying pH-responsive features, discussing various types of pH-responsive nanocarriers, their advantages, and limitations. Innovative therapeutic drugs are also examined, followed by an exploration of recent advancements in applying various pH-responsive nanocarriers as delivery systems for enhanced tumor therapy. pH-responsive nanocarriers have garnered significant attention for their capability to achieve targeted accumulation of therapeutic agents at tumor sites and controlled drug delivery profiles, ultimately increasing the efficiency of tumor eradication. It is anticipated that the employment of pH-responsive nanocarriers will elevate the effectiveness and safety of tumor therapy, contributing to improved overall outcomes.

description: In this paper we discuss several heuristic strategies which allow one to solve the Whitehead's minimization problem much faster (on most inputs) than the classical Whitehead algorithm. The mere fact that these strategies work in practice leads to several interesting mathematical conjectures. In particular, we conjecture that the length of most non-minimal elements in a free group can be reduced by a Nielsen automorphism which can be identified by inspecting the structure of the corresponding Whitehead Graph.
New Galaxy tools for flow and mass single-cell cytometry
Creators: name: Mirek Kratochvil
Publisher: name: F1000 Research Limited
Year: 2019

description: Analysis of single-cell cytometry datasets is most complicated by the tedious nature of manually picking cell populations from high-dimensional measurement space. We have previously created new FlowSOM-based tools to expedite, automate and unbias the dissection procedure; including the EmbedSOM visualization and DiffSOM hierarchical analysis workflow.
We now present ShinySOM, the RShiny-based user-friendly front-end for running the new workflows. In combination with Galaxy-based cloud-computing, we deliver a new interactive, scalable, reproducible and robust analysis platform for supporting the cytometry user base.

description: We report anisotropic resistivity measurements of the heavy-fermion superconductor CeRh$_2$As$_2$ in magnetic fields up to 16 T and temperatures down to 0.35 K. The measured CeRh$_2$As$_2$ resistivity shows a signature corresponding to the suggested quadrupole density wave order state at $T_0 \sim$ 0.5 K for both measured directions. For a magnetic field applied along the tetragonal $a$ axis, $T_0$ is enhanced with magnetic field reaching $\sim$1.75 K at 16 T. Further, a magnetic field-induced transition occurs at $B_m \sim $ 8.1 T corresponding to a change to a new broken symmetry state. For a magnetic field applied along the $c$ axis, $T_0$ is suppressed below our base temperature $\sim$0.35 K by $B \sim$ 4.5 T, a field close to the previously reported field-induced transition within the superconducting state suggested to be from an even-parity to an odd-parity state. Our results indicate that the multiple superconducting phases in CeRh$_2$As$_2$ are intimately tied to the suppression of the proposed quadrupole-density-wave phase at $T_0$.

description: We derive the luminosity-temperature relation for clusters of galaxies by means of a modification of the self-similar model to take account of angular momentum acquisition by protostructures and of an external pressure term in the virial theorem. The fundamental result of the model is that gravitational collapse, which takes account of angular momentum acquisition, can explain the non self-similarity in the L-T relation, in disagreement with the largely accepted assumption that heating/cooling processes and similar are fundamental in the originating the non-self similar behavior (shaping) of the L-T relation.

Class of PPT bound entangled states associated to almost any set of pure entangled states

name: Mora, C.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)

description: We analyze a class of entangled states for bipartite $d \otimes d$ systems, with $d$ non-prime. The entanglement of such states is revealed by the construction of canonically associated entanglement witnesses. The structure of the states is very simple and similar to the one of isotropic states: they are a mixture of a separable and a pure entangled state whose supports are orthogonal. Despite such simple structure, in an opportune interval of the mixing parameter their entanglement is not revealed by partial transposition nor by the realignment criterion, i.e. by any permutational criterion in the bipartite setting. In the range in which the states are Positive under Partial Transposition (PPT), they are not distillable; on the other hand, the states in the considered class are provably distillable as soon as they are Nonpositive under Partial Transposition (NPT). The states are associated to any set of more than two pure states. The analysis is extended to the multipartite setting. By an opportune selection of the set of multipartite pure states, it is possible to construct mixed states which are PPT with respect to any choice of bipartite cuts and nevertheless exhibit genuine multipartite entanglement. Finally, we show that every $k$-positive but not completely positive map is associated to a family of nondecomposable maps.

Designing contextually relevant digital interpretation for a public garden
Creators: name: Edwards, Liz
Publisher: name: Lancaster University
Year: 2019

description: This thesis is concerned with the design of digital technologies, particularly digital interpretation, to reveal the natural world and support human connection to natural places. The natural world is under an accelerating threat as a result of human behaviour and increased technology use is perceived to be part of the problem. Some philosophers have made a connection between the design of technology and the behavioural and attitudinal tendencies elicited through the use of technology. Whether or not this is true it is an interesting area of research. The research project described explores the use of criticism of technology, taken from a selection of critical theory writings, as a design lens to inform design process and the design of digital artefacts for use in nature. The research draws heavily on the work of Heidegger, Borgmann and Feenberg to inform the design lens. The first phase of the research involved drawing out design criteria from the critiques of technology. The next phase of the research which drew on Reflective Practice and Research through Design, applied the design lens to a prototype design which was intended to be used to build connection with a woodland area. The subsequent research involved a longterm collaboration with gardeners and volunteers at the Walled Kitchen Garden in Clumber Park, a National Trust property in Nottinghamshire. The research explored the use of the design principles drawn from critical theory to create and evaluate digital interpretation for the garden. The open and reflective research approach allowed for the evolution of new research questions through the process. This led to additional questions about sustaining digital interpretation and designing for active engagement. The findings suggest that the designs produced using the lens drawn from critical theory are distinct and contextually relevant designs that have a ‘family resemblance’. The research shows that the design principles drawn from critical theory resulted in an embedded, design process that was highly responsive to context. One of the contributions of the research is a set of recommendations to be considered when designing digital interpretation for organisations with an interest in environmental issues. The research also results in tentative contributions towards a digital nature strand for the primary school curriculum involving cross-curricular, multi-sensory and multi-dimensional activities to build connection to natural environments.

description: We study a feedback control version of the flashing Brownian ratchet, in which the application of the flashing potential depends on the state of the particles to be controlled. Taking the view that the ratchet acts as a Maxwell's demon, we study the relationship that exists between the performance of the demon as a rectifier of random motion and the amount of information gathered by the demon through measurements. In the context of a simple measurement model, we derive analytic expressions for the flux induced by the feedback ratchet when acting on one particle and a few particles, and compare these results with those obtained with its open-loop version, which operates without information. Our main finding is that the flux in the feedback case has an upper bound proportional to the square-root of the information. Our results provide a quantitative analysis of the value of information in feedback ratchets, as well as an effective description of imperfect or noisy feedback ratchets that are relevant for experimental applications.

Building interpersonal trust in business networks: enablers and roadblocks
Creators: name: Hakanen, Mila Susanna
name: Kossou, Leila

Publisher: name: Journal of Business Models
Year: 2019

description: Purpose - This study examines how interpersonal trust forms in business networks and anchors relationships. Trust can be seen as a required factor and enabler for co-creation that is needed when business models are created. This study draws on empirical data from a case study of a Finnish business network in the healthcare and pharmaceutical industries. It seeks to answer the research question: How does interpersonal trust start to develop at the business network level and how it can be supported? Design/ methodology/approach – This article draws on a case study of a Finnish business network which was developed through theme interviews and observation conducted in 2012. Findings - The findings support existing research on interpersonal trust, and emphasize three key characteristics of interpersonal trust building: (1) It is a slow process that can be easily discontinued by definite roadblocks. (2) It requires that the parties have knowledge about one another and a rapport; that they show respect and fairness, keep their promises, and most importantly, communicate effectively. (3) It should be based on shared responsibilities among the network members. The key finding is the importance of informal meetings that is not highly noticed in the research field. Informal meetings support more the building of we-spirit and crazy ideas that are important when new business models and innovations are built. Research limitations/implications – This case study considers one business network in Finland. Further research would be required in order to generalise the findings on a larger scale or to other contexts. Practical implications – This study is highly practical oriented and it offers practical guidance and support for business partners in the early stages of networking by highlighting the role of trust formation. Originality/value - Despite the significant attention given to interpersonal trust in management literature, less research has focused on understanding how it forms in inter-organisational settings. Moreover, the focus is usually in dyadic relations in network studies but this study focus on the level of whole network. Keywords - Business networks; Business Modelling; Communication; Distrust; Networking; Social Capital; Trust Article Classification - Case study

Publisher: name: Journal of Business Models
Year: 2019

description: Purpose: The purpose of the paper is to analyse founders’ perceptions of initial configurations and business models in new technology-based firms (NTBFs). Design: Case studies were performed using semi-structured interviews and interactive techniques involving open questions and activity cards to capture perceptions of activities that form the firms’ business models. Findings: The Business Model template, commonly referred to as the Business Model Canvas, is frequently used among these companies and seemed to have shaped the business model discourse in our case companies. Our findings also indicate that founders of NTBFs perceive their customer value proposition as the most valuable element of their business model. We also recognized signs of the influence of financial partners on the founders’ perceptions of the initial business models. Furthermore, findings show that some NTBFs create parallel business models within their firms to ensure survival in the start-up phase. Originality/value: The paper adds value to business model research by describing how NTBFs’ structure their initial business activities and the elements of their initial business models perceived to be as more crucial during the early years as well as how these perceptions change.

Exploring Value as the Foundation of Value Proposition Design

Publisher: name: Journal of Business Models
Year: 2019

description: Purpose: Business models define the activity system that an organization employs to create and capture value. As such, business models are essentially the application of strategic management. The term business model, however, suffers from definitional ambiguity which makes the construction of effective business models problematic. We argue that this ambiguity is largely due to a lack of clarity around value. This paper seeks to provide clarity around value and in doing so aid in the development of effective business models. Design: Theoretical paper that deconstructs value into use value and exchange value and develops these concepts. Findings: We deconstruct value into use value and exchange value to explain the micro-conditions of value creation and capture. In doing so, we also provide an explanation of how VRIN and non-VRIN resources can be traded for gain as well as opening up greater strategic options for managers in their development of business models. Originality / Value: Against the background of the study’s focus on BMI, its comparably broad literature basis, and its quantitative and qualitative analysis approach, which provides straightforward recommendations for future research, the study caters an original contribution to the field.

It is characterized as antiferromagnetic semiconductor around LaOMnAs side and ferromagnetic metal around LaOCoAs. Both LaOFeAs and LaONiAs, where superconductivity were discovered, are located at the borderline of magnetic phases. Extensive Fermi surface analysis suggests that the observed superconductivity is of electron-type in its origin. We discuss possible pairing mechanisms in the context of competing ferromagnetic phases found in this work and the ferromagnetic spin fluctuations.

description: Band-to-band tunneling (BTBT) devices have recently gained a lot of interest due to their potential for reducing power dissipation in integrated circuits. We have performed extensive simulations for the BTBT operation of carbon nanotube metal-oxide-semiconductor field-effect transistors (CNT-MOSFETs) using the non-equilibrium Green's functions formalism for both ballistic and dissipative quantum transport. In comparison with recently reported experimental data (Y. Lu et al, J. Am. Chem. Soc., v. 128, p. 3518-3519, 2006), we have obtained strong evidence that BTBT in CNT-MOSFETs is dominated by optical phonon assisted inelastic transport, which can have important implications on the transistor characteristics. It is shown that under large biasing conditions two-phonon scattering may also become important.

description: Optimal control methods for implementing quantum modules with least amount of relaxative loss are devised to give best approximations to unitary gates under relaxation. The potential gain by optimal control using relaxation parameters against time-optimal control is explored and exemplified in numerical and in algebraic terms: it is the method of choice to govern quantum systems within subspaces of weak relaxation whenever the drift Hamiltonian would otherwise drive the system through fast decaying modes. In a standard model system generalising decoherence-free subspaces to more realistic scenarios, openGRAPE-derived controls realise a CNOT with fidelities beyond 95% instead of at most 15% for a standard Trotter expansion. As additional benefit it requires control fields orders of magnitude lower than the bang-bang decouplings in the latter.

description: Quantum networking holds tremendous promise in transforming computation and communication. While matter-based systems excel as memory nodes, photons are ideal for long-distance transmission. Hence, a hybrid network combining both becomes essential. Moreover, developing entangled photon pair sources is critical for quantum repeaters and network implementation. The realization of these capabilities on integrated photonic circuits is vital for miniaturization and scalability. In this dissertation, we focus on two key aspects: establishing efficient photon-to-memory interfaces and generating and manipulating entangled states within integrated platforms.One research direction involves developing an efficient interface between photons and matter-based memory, requiring spectral and temporal mode matching. Spectral compression is inevitable to realize low-loss interconnection between intrinsically narrowband memories and broadband photons. We proposed a novel approach using electro-optic time-varying cavities for spectral compression. Currently, we are working toward realizing this approach on the thin film lithium niobate platform.In the other research focus, we encode quantum information as a coherent superposition of multiple optical frequencies; this approach is favorable due to its simplicity in generating high-dimensional entanglement and compatibility with fiber transmission. We successfully generated and reconstructed the density matrix of biphoton frequency combs from integrated silicon nitride microrings, achieving an 8x8 two-qudit dimensionality, the highest to date for frequency-bin qudits. Moreover, we employ Vernier electro-optic phase modulation methods to perform time-resolved measurements of biphoton correlation functions. Currently, we are exploring bidirectional pumping of microrings to generate indistinguishable entangled pairs in both directions, aiming to demonstrate key networking operations such as entanglement swapping and GHZ state generation in the frequency domain. We are also pursuing bidirectional pumping in a Sagnac configuration to generate simultaneous entanglement in both polarization and frequency, with the goal of deployment in a wavelength-multiplexednetwork.

description: Πραγματοποιήθηκε διερεύνση βιομαρτύρων ρύπανσης έπειτα από μια σειρά ερευνών στο πεδίο και στο εργαστήριο χρησιμοποιώντας μύδια M. galloprovincialis. Τα αποτελέσματα ενίσχυσαν την εφαρμογή της 'σταθερότητας της λυσοσωμικής μεμβράνης' και 'κατακράτηση της χρωστικής ουδέτερο ερυθρό', ενώ κατέδειξαν πως απαιτείται περαιτέρω διερεύνηση των βιομαρτύρων 'εκτίμηση στρες, καθώς και της μορφομετρίας των λυσοσωμάτων και των λιπιδίων για την εφαρμιογή τους στη βιοπαρακολούθηση της ρύπανσης. Ο βιομάρτυρας 'συχνότητα συνολικών πυρηνικών ανωμαλίων αποδείχθηκε περισσότερο ευαίσθητος από τη 'συχνότητα μικροπυρήνων' για τον προσδιορισμό των γενοτοξικών βλαβών. Επίσης μελετήθηκε η εποχική μεταβολή των χαρακτηριστικών του λυσοσωμικού συστήματος και η διακύμανση των λιπιδίων και των λιποφουσκινών στον πεπτικό αδένα. Στην αρχή του καλοκαιριού τα πεπτικά σωληνάρια εμφανίστηκαν ιδιαιτέρως ενεργά, στην αρχή του χειμώνα η λειτουργία τους φάνηκε να καταστέλλεται, ενώ στην αρχή της άνοιξης εμφανίσθηκαν σημάδια ενεργοποίησης. Η περίοδος από το τέλος της άνοιξης έως τα μέσα καλοκαιριού αποτελεί την καταλληλότερη εποχή για την εφαρμογή βιομαρτύρων που σχετίζονται με παραμέτρους του πετπικού αδένα των μυδιών
description: Various pollution biomarkers were examined in field and laboratory studies using mussels M. gallogrovinciallis. The biomakers 'Lysosomal membrane stability' and 'neutral red retention assay' were further supported by the results, while the 'stress on stress' and the morhometrical changes of lysosomes and lipids seemed to require additional valiolation before their application in biomonitoring. The evaluation of 'total nuclear abnormalities' indicated more precisely the genotoxic damage than the 'micronucleus frequency'. The seasonal influence on structural parameters of the lysosomal system, as well as on the variation of lipids and lipofuscin were also examined. Active digestive tubules appeared in early summer, inactivation in early summer, inactivation in early winter and reactivation in early spring. According to the results the period between the end of spring and the middle of summer represents the most appropriate time for biomarkers of dealing with digestive gland parameters in mussels

description: A dedicated in situ heating setup in a scanning electron microscope (SEM) followed by an ex situ atomic force microscopy (AFM) and electron backscatter diffraction (EBSD) is used to characterize the nucleation and early growth stages of Fe-Al intermetallics (IMs) at 596 °C. A location tracking is used to interpret further characterization. Ex situ AFM observations reveal a slight shrinkage and out of plane protrusion of the IM at the onset of IM nucleation followed by directional growth. The formed interfacial IM compounds were identified by ex situ EBSD. It is now clearly demonstrated that the θ-phase nucleates first prior to the diffusion-controlled growth of the η-phase. The θ-phase prevails the intermetallic layer.

Mitigating Shadows in Lidar Scan Matching using Spherical Voxels

description: In this paper we propose an approach to mitigate shadowing errors in Lidar scan matching, by introducing a preprocessing step based on spherical gridding. Because the grid aligns with the Lidar beam, it is relatively easy to eliminate shadow edges which cause systematic errors in Lidar scan matching. As we show through simulation, our proposed algorithm provides better results than ground-plane removal, the most common existing strategy for shadow mitigation. Unlike ground plane removal, our method applies to arbitrary terrains (e.g. shadows on urban walls, shadows in hilly terrain) while retaining key Lidar points on the ground that are critical for estimating changes in height, pitch, and roll. Our preprocessing algorithm can be used with a range of scan-matching methods; however, for voxel-based scan matching methods, it provides additional benefits by reducing computation costs and more evenly distributing Lidar points among voxels.
Shock processing of interstellar dust and polycyclic aromatic hydrocarbons in the supernova remnant N132D

description: We observed the oxygen-rich Large Magellanic Cloud (LMC) supernova remnant N132D (SNR 0525-69.6), using all instruments onboard the Spitzer Space Telescope, IRS, IRAC, and MIPS (Infrared Spectrograph, Infrared Array Camera, Multiband Imaging Photometer for Spitzer). The 5-40 micron IRS spectra toward the southeastern shell of the remnant show a steeply rising continuum with [NeIII] and [OIV] as well as PAH emission. We also present the spectrum of a fast moving ejecta knot, previously detected at optical wavelengths, which is dominated by strong [NeIII] and [OIV] emission lines. We interpret the continuum as thermal emission from swept-up, shock-heated dust grains in the expanding shell of N132D, which is clearly visible in the MIPS 24 micron image. A 15-20 micron emission hump appears superposed on the dust continuum, and we attribute this to PAH C-C-C bending modes. We also detect the well-known 11.3 micron PAH C-H bending feature, and find the integrated strength of the 15-20 micron hump about a factor of seven stronger than the 11.3 micron band in the shell of the remnant. IRAC 3-9 micron images do not show clear evidence of large-scale, shell-like emission from the remnant, partly due to confusion with the ambient ISM material. However, we identified several knots of shocked interstellar gas based on their distinct infrared colors. We discuss the bright infrared continuum and the polycyclic aromatic hydrocarbon features with respect to dust processing in young supernova remnants.

description: The Event Horizon Telescope (EHT) collaboration, an Earth-size sub-millimetre radio interferometer, recently captured the first images of the central supermassive black hole in M87. These images were interpreted as gravitationally-lensed synchrotron emission from hot plasma orbiting around the black hole. In the accretion flows around low-luminosity active galactic nuclei such as M87, electrons and ions are not in thermal equilibrium. Therefore, the electron temperature, which is important for the thermal synchrotron radiation at EHT frequencies of 230 GHz, is not independently determined. In this work, we investigate the commonly used parameterised ion-to-electron temperature ratio prescription, the so-called R-$β$ model, considering images at 230 GHz by comparing with electron-heating prescriptions obtained from general-relativistic magnetohydrodynamical (GRMHD) simulations of magnetised accretion flows in a Magnetically Arrested Disc (MAD) regime with different recipes for the electron thermodynamics. When comparing images at 230 GHz, we find a very good match between images produced with the R-$β$ prescription and those produced with the turbulent- and magnetic reconnection- heating prescriptions. Indeed, this match is on average even better than that obtained when comparing the set of images built with the R-$β$ prescription with either a randomly chosen image or with a time-averaged one. From this comparative study of different physical aspects, which include the image, visibilities, broadband spectra, and light curves, we conclude that, within the context of images at 230 GHz relative to MAD accretion flows around supermassive black holes, the commonly-used and simple R-$β$ model is able to reproduce well the various and more complex electron-heating prescriptions considered here.

description: Der Krankheitsverlauf bei CED-Patienten lässt sich aktuell nur unzureichend vorhersagen, prädiktive Marker stehen nur eingeschränkt zur Verfügung. Die hier vorgestellten Arbeiten beschäftigen sich mit dem Zusammenhang zwischen Darmmikrobiom, Vitamin D und genetischen Risikofaktoren, wie Mutationen im NOD2 Gen bei CED. Aus den hier durchgeführten Untersuchungen resultiert u.a. ein besseres Verständnis darüber, wie sich die einzelnen Faktoren gegenseitig beeinflussen und eine Auswirkung auf den Krankheitsverlauf bei CED haben.

description: We study the interface between a solid trapped within a bath of liquid by a suitably shaped non-uniform external potential. Such a potential may be constructed using lasers, external electric or magnetic fields or a surface template. We study a two dimensional case where a thin strip of solid, created in this way, is surrounded on either side by a bath of liquid with which it can easily exchange particles. Since height fluctuations of the interface cost energy, this interface is constrained to remain flat at all length scales. However, when such a solid is stressed by altering the depth of the potential; beyond a certain limit, it responds by relieving stress by novel interfacial fluctuations which involve addition or deletion of entire lattice layers of the crystal. This ``layering'' transition is a generic feature of the system regardless of the details of the interaction potential. We show how such interfacial fluctuations influence mass, momentum and energy transport across the interface. Tiny momentum impulses produce weak shock waves which travel through the interface and cause the spallation of crystal layers into the liquid. Kinetic and energetic constraints prevent spallation of partial layers from the crystal, a fact which may be of some practical use. We also study heat transport through the liquid-solid interface and obtain the resistances in liquid, solid and interfacial regions (Kapitza resistance) as the solid undergoes such layering transitions. Heat conduction, which shows strong signatures of the structural transformations, can be understood using a free volume calculation.
