description: Quantum key agreement enables remote participants to fairly establish a secure shared key based on their private inputs. In the circular-type multiparty quantum key agreement mode, two or more malicious participants can collude together to steal private inputs of honest participants or to generate the final key alone. In this work, we focus on a powerful collusive attack strategy in which two or more malicious participants in particular positions, can learn sensitive information or generate the final key alone without revealing their malicious behaviour. Many of the current circular-type multiparty quantum key agreement protocols are not secure against this collusive attack strategy. As an example, we analyze the security of a recently proposed multiparty key agreement protocol to show the vulnerability of existing circular-type multiparty quantum key agreement protocols against this collusive attack. Moreover, we design a general secure multiparty key agreement model that would remove this vulnerability from such circular-type key agreement protocols and describe the necessary steps to implement this model. The proposed model is general and does not depend on the specific physical implementation of the quantum key agreement.

Non-existential risks
Surgisphere scandal
AI for health

description: Solid analytical work in philosophy has clearly defined the real possibility of existential harm to humanity by general artificial intelligence (AI) and argued that existential risk prevention is a global priority. Such existential risk scenarios of a “super AI” exterminating humankind have a rich and powerful attraction to our imagination. In contrast, here I claim that the main practical aim of the philosophy of AI for health should be the study of non-existential risks of AI health interventions, including AI scientific health claims. I will call this “the duty to study the non-existential risks of AI health interventions”. To support this duty, I will argue that harm to individuals, groups, or populations with AI health interventions is not just a probability that may happen in the future but is instead a reality already happening in the present, with consequences for our understanding of traditional duties and something that can be averted or minimized with simple safeguards. The Surgisphere database scandal during the COVID-19 pandemic illustrates the first point. The AI scientific claims —published in The Lancet and NEJM, based on a fraudulent global database that allegedly used AI/ML to automate processes— made governments and the World Health Organization (WHO) change their health policy with harmful results. If this argument is sound, three traditional duties of health professions gain a new meaning in the philosophy of AI for health. First, the duty to care brings support to the main idea of this presentation that the philosophy of AI for health should prioritize the study of non-existential risks, as we prioritize some patients to emergency care over research in medicine. Second, once we know of non-existential risks, the duty to do no harm justifies implementing appropriate safeguards in the work of health professionals (e.g. medicine, nursing, pharmacy, and public health) and data scientists who are currently developing and using AI health interventions. Third, the duty of justice states that we should redress unfair inequalities related to AI health interventions, such as improving AI education for health professionals and the national government's capacity to evaluate AI scientific claims —usually from low- and middle-income countries that are at a higher risk of non-existential harms. Finally, I will share some examples of simple appropriate safeguards (e.g., SPIRIT-AI guidelines for clinical trial presentations, support from WHO) and attempt to address general objections to its implementation such as futility, stifling the benefits of health innovation, and trade secret confidentiality

description: Excerpts: Government intervention in the food and fiber sector is seldom neutral with respect to its impact on the structure of agriculture. Even programs and policies not directly targeted towards agriculture can have important influences. Few would argue that technological change has not had an overriding influence on structure and much has been written concerning its effects. However, we will argue the cumulative effect of nontechnological programs and policies are also important. Further, within the framework of adaptive control processes, these programs and policies are the primary control variables through which the Federal Government can influence the rate of change in the structure and ultimately, who controls agriculture. The objective of this paper is to catalogue and analyze nontechnological programs and policies of the Federal Government and their impact on the structure of agriculture. Two earlier studies, Quance and Tweeten [17] and Dahl [6], focused attention on this subject. However, this paper has a much broader scope in terms of the number of programs and policies analyzed.

description: A PT-symmetric Bose-Einstein condensate can be theoretically described using a complex optical potential, however, the experimental realization of such an optical potential describing the coherent in- and outcoupling of particles is a nontrivial task. We propose an experiment for a quantum mechanical realization of a PT-symmetric system, where the PT-symmetric currents of a two-well system are implemented by coupling two additional wells to the system, which act as particle reservoirs. In terms of a simple four-mode model we derive conditions under which the two middle wells of the Hermitian four-well system behave exactly as the two wells of the PT-symmetric system. We apply these conditions to calculate stationary solutions and oscillatory dynamics. By means of frozen Gaussian wave packets we relate the Gross-Pitaevskii equation to the four-mode model and give parameters required for the external potential, which provides approximate conditions for a realistic experimental setup.

description: We compute the expansion of the cohomology class of the permutahedral variety in the basis of Schubert classes. The resulting structure constants $a_w$ are expressed as a sum of \emph{normalized} mixed Eulerian numbers indexed naturally by reduced words of $w$. The description implies that the $a_w$ are positive for all permutations $w\in S_n$ of length $n-1$, thereby answering a question of Harada, Horiguchi, Masuda and Park. We use the same expression to establish the invariance of $a_w$ under taking inverses and conjugation by the longest word, and subsequently establish an intriguing cyclic sum rule for the numbers. We then move toward a deeper combinatorial understanding for the $a_w$ by exploiting in addition the relation to Postnikov's divided symmetrization. Finally, we are able to give a combinatorial interpretation for $a_w$ when $w$ is vexillary, in terms of certain tableau descents. It is based in part on a relation between the numbers $a_w$ and principal specializations of Schubert polynomials. Along the way, we prove results and raise questions of independent interest about the combinatorics of permutations, Schubert polynomials and related objects. We also sketch how to extend our approach to other Lie types, highlighting in particular an identity of Klyachko.

description: Excerpts from the report: The rapid expansion of the use of pallet boxes in the apple industry has brought about many changes in handling and packing operations, and made, cost-reducing mechanization practical. One of the important innovations was the development of an automatic pallet-box filler. Such a filler should achieve low-cost filling of apples into pallet boxes, so that fruit can be sized and sorted before it is placed in storage. Presizing and presorting allow the removal of small and off-grade fruits, and thus make available more cold-storage space for marketable quality fruit. It also should facilitate treatment of the fruit with a scald-preventive chemical. Perhaps an even more, far-reaching ramification will be the distribution of apples in pallet boxes to terminal markets. An automatic pallet-box filler would make this practical by keeping costs in the packing plant low and volume high. In developing the pallet-box filler, three different designs were conceived, and operating models made. The first two were not successful. This report will deal primarily with the work on the third, a successful design.

description: We study an optomechanical system in which a microwave field and an optical field are coupled to a common mechanical resonator. We explore methods that use these mechanical resonators to store quantum mechanical states and to transduce states between the electromagnetic resonators from the perspective of the effect of mechanical decoherence. Besides being of fundamental interest, this coherent quantum state transfer could have important practical implications in the field of quantum information science, as it potentially allows one to overcome intrinsic limitations of both microwave and optical platforms. We discuss several state transfer protocols and study their transfer fidelity using a fully quantum mechanical model that utilizes quantum state-diffusion techniques. This work demonstrates that mechanical decoherence should not be an insurmountable obstacle in realizing high fidelity storage and transduction.

description: Excerpts from the report: Substantial amounts of money and effort are being invested by farm groups and processors of agricultural products in promotion activities. In 1958, it was estimated that some 1,100 farm groups or organizations were engaged in promotion activities, spending around $75 million annually to maintain and strengthen their markets. These groups primarily represent producers and those engaged in marketing farm products who have banded together in commissions, councils, boards, and cooperatives to sell more of their products. The membership of these groups ranges from less than a hundred to over a million. Some groups draw their membership from a single State, others are regional, and some are national in scope. To assist these groups and to provide comparative benchmarks for those more experienced in promotion, a study was undertaken to analyze the promotion practices followed by selected producer-oriented promotion groups, commercial food firms, and advertising agencies. The objectives of this analysis were to: (1) Determine promotion methods and programs used by agricultural groups to create demand for their respective products, (2) ascertain the organizational structure and practices used to administer promotion activities, (3) appraise advertiser-agency relationships and responsibilities in carrying out promotion programs, (4) determine the amount of expenditure for the several phases of promotion programs and the manner in which payments to advertising and public relation agencies are allocated among different services provided by the agencies, and (5) provide a basis for making broad recommendations for increasing the effectiveness of programs to create demands.

description: Splitting nitrogen (N) application is beneficial for achieving higher grain yields and N use efficiency (NUE), but the responses of N utilization efficiency of different maize cultivars to top-dressing N fertilizer rates are still unclear. This study investigated the effects of fertilization managements on N uptake and utilization derived from topdressing fertilizers of maize hybrids (Ludan981 and Denghai605) with contrasting NUEs. The N fate derived from topdressing fertilizer was determined using the 15N tracing method. Grain yields, dry matter and N accumulation of both maize hybrids were significantly increased under low N levels but decreased under high N levels. Under N-deficient and excess conditions, Denghai605 had higher NUE than Ludan981. The N rates of topdressing significantly affected N uptake and utilization, but no difference was detected between two maize hybrids, and excessive N use led to higher rates of N loss and residual in soil. The N metabolism enzyme activities did not differ between the two maize hybrids. Our findings suggest optimized N management strategies by adjusting topdressing N application rate and timing are necessary to increase NUE and to minimize environmental costs in maize cropping system.

description: We construct a model structure on the category $\mathrm{DblCat}$ of double categories and double functors, whose trivial fibrations are the double functors that are surjective on objects, full on horizontal and vertical morphisms, and fully faithful on squares; and whose fibrant objects are the weakly horizontally invariant double categories. We show that the functor $\mathbb H^{\simeq}\colon \mathrm{2Cat}\to \mathrm{DblCat}$, a more homotopical version of the usual horizontal embedding $\mathbb H$, is right Quillen and homotopically fully faithful when considering Lack's model structure on $\mathrm{2Cat}$. In particular, $\mathbb H^{\simeq}$ exhibits a levelwise fibrant replacement of $\mathbb H$. Moreover, Lack's model structure on $\mathrm{2Cat}$ is right-induced along $\mathbb H^{\simeq}$ from the model structure for weakly horizontally invariant double categories. We also show that this model structure is monoidal with respect to Böhm's Gray tensor product. Finally, we prove a Whitehead Theorem characterizing the weak equivalences with fibrant source as the double functors which admit a pseudo inverse up to horizontal pseudo natural equivalence.
description: 39 pages. We fixed an error in our previous characterization of the class of weak equivalences, pointed out by an anonymous referee. The paper was thoroughly rewritten, with major changes in the techniques used to obtain the model structure

description: Adopting Convolutional Neural Networks (CNNs) in the daily routine of primary diagnosis requires not only near-perfect precision, but also a sufficient degree of generalization to data acquisition shifts and transparency. Existing CNN models act as black boxes, not ensuring to the physicians that important diagnostic features are used by the model. Building on top of successfully existing techniques such as multi-task learning, domain adversarial training and concept-based interpretability, this paper addresses the challenge of introducing diagnostic factors in the training objectives. Here we show that our architecture, by learning end-to-end an uncertainty-based weighting combination of multi-task and adversarial losses, is encouraged to focus on pathology features such as density and pleomorphism of nuclei, e.g. variations in size and appearance, while discarding misleading features such as staining differences. Our results on breast lymph node tissue show significantly improved generalization in the detection of tumorous tissue, with best average AUC 0.89 (0.01) against the baseline AUC 0.86 (0.005). By applying the interpretability technique of linearly probing intermediate representations, we also demonstrate that interpretable pathology features such as nuclei density are learned by the proposed CNN architecture, confirming the increased transparency of this model. This result is a starting point towards building interpretable multi-task architectures that are robust to data heterogeneity.

description: Web services are building blocks of interoperable systems. Composing Web services makes the processes capable of doing complex tasks. Composite services may fail during their execution which can be diagnosed by a mediator. The mediator adapts the structure so that the failure is recovered. Moreover, future executions should avoid the situation or organize a strategy to repair the structure with a minimum delay. In this paper the failure reasons of a composite service are reviewed. Furthermore, the requirements of a solution for recovery of a system from a failure are investigated.

description: Recently the first author studied the bifurcation of critical points of families of functionals on a Hilbert space, which are parametrised by a compact and orientable manifold having a non-vanishing first integral cohomology group. We improve this result in two directions: topologically and analytically. From the analytical point of view we generalise it to a broader class of functionals; from the topological point of view we allow the parameter space to be a metrisable Banach manifold. Our methods are in particular powerful if the parameter space is simply connected. As an application of our results we consider families of geodesics in (semi-) Riemannian manifolds.

description: A linear algebraic group G is over a field K is called a Cayley K-group if it admits a Cayley map, i.e., a G-equivariant K-birational isomorphism between the group variety G and its Lie algebra. We classify real reductive algebraic groups of absolute rank 1 and 2 that are Cayley R-groups.

description: Υπάρχουν πολλά ετερογενή φυσικά και τεχνητά υλικά. Ο απευθείας υπολογισμός των αποτελεσμάτων μίας προσομοίωσης με ετερογενή υλικά είναι συχνά χρονοβόρος. Για αυτό συχνά είναι απαραίτητη μία άλλη προσέγγιση. Η λύση που εξετάζεται σε αυτή την εργασία είναι η ομογενοποίηση. Η δημιουργία δηλαδή ενός μόνο υλικού που έχει τις μέσες ιδιότητες των διαφόρων υλικών μίας σύνθετης κατασκευής. Σε αυτήν την εργασία έγινε μία προσπάθεια να ομογενοποιηθεί μία κατασκευή που αποτελείται από ένα πιεζοηλεκτρικό και ένα ελαστικό υλικό. Τα πιεζοηλεκτρικά υλικά έχουν την μοναδική ιδιότητα να μετατρέπουν την ηλεκτρική φόρτιση σε μηχανική και το αντίστροφο. Η μέθοδος που εφαρμόστηκε στο τρισδιάστατο μοντέλο μπορεί να δώσει εύκολα αποτελέσματα καθώς με την βοήθεια εννιά περιπτώσεων φόρτισης υπολογίζεται με μία απλή πράξη κάθε μία από τους παραμέτρους του πιεζοσύνθετου υλικού. Τα αποτελέσματα της μεθόδου είναι αρκετά ενθαρρυντικά καθώς η απόκλιση τους με τα θεωρητικά ήταν μικρή.

description: In this manuscript we study tridiagonal random matrix models related to the classical $β$-ensembles (Gaussian, Laguerre, Jacobi) in the high temperature regime, i.e. when the size $N$ of the matrix tends to infinity with the constraint that $βN=2α$ constant, $α> 0$. We call these ensembles the Gaussian, Laguerre and Jacobi $α$-ensembles and we prove the convergence of their empirical spectral distributions to their mean densities of states and we compute them explicitly. As an application we explicitly compute the mean density of states of the Lax matrix of the Toda lattice with periodic boundary conditions with respect to the Gibbs ensemble.

description: Fluoroscopy is a radiographic procedure for evaluating esophageal disorders such as achalasia, dysphasia and gastroesophageal reflux disease (GERD). It performs dynamic imaging of the swallowing process and provides anatomical detail and a qualitative idea of how well swallowed fluid is transported through the esophagus. In this work, we present a method called mechanics informed fluoroscopy (FluoroMech) that derives patient-specific quantitative information about esophageal function. FluoroMech uses a Convolutional Neural Network to perform segmentation of image sequences generated from the fluoroscopy, and the segmented images become input to a one-dimensional model that predicts the flow rate and pressure distribution in fluid transported through the esophagus. We have extended this model by developing a FluoroMech reference model to identify and estimate potential physiomarkers such as esophageal wall stiffness and active relaxation ahead of the peristaltic wave in the esophageal musculature. FluoroMech requires minimal computational time, and hence can potentially be applied clinically in the diagnosis of esophageal disorders.

description: It is unknown how far dust growth can proceed by coagulation. Obstacles to collisional growth are the fragmentation and bouncing barriers. However, in all previous simulations of the dust-size evolution in protoplanetary disks, only the mean collision velocity has been considered, neglecting that a small but possibly important fraction of the collisions will occur at both much lower and higher velocities. We study the effect of the probability distribution of impact velocities on the collisional dust growth barriers. Assuming a Maxwellian velocity distribution for colliding particles to determine the fraction of sticking, bouncing, and fragmentation, we implement this in a dust-size evolution code. We also calculate the probability of growing through the barriers and the growth timescale in these regimes. We find that the collisional growth barriers are not as sharp as previously thought. With the existence of low-velocity collisions, a small fraction of the particles manage to grow to masses orders of magnitude above the main population. A particle velocity distribution softens the fragmentation barrier and removes the bouncing barrier. It broadens the size distribution in a natural way, allowing the largest particles to become the first seeds that initiate sweep-up growth towards planetesimal sizes.

description: We study the dynamics of spontaneous generation of coherence and photon spin-qubit entanglement or "flying qubits" in a $Λ$ system with non-degenerate lower levels. The cases of entanglement in frequency only and frequency and polarization are compared and the reduced density matrix and entanglement entropy are analyzed. We explore in detail how which-path information manifest when the energy difference between the qubit states is larger than the linewidth of the excited state suppresses coherence. A framework is provided to describe the complete dynamics of spontaneous generation of coherence and (ideal) photodetection obtaining the post measurement qubit density matrix. A simple model of photodetection with a quantum eraser to suppress which-path information in the detection measurement is implemented. It is found that such quantum eraser purifies the post measurement qubit density matrix establishing contact with recent experiments.

description: Spatiotemporal dynamics of excitons in isolated semiconducting single-walled carbon nanotubes are studied using transient absorption microscopy. Differential reflection and transmission of an 810-nm probe pulse after excitation by a 750-nm pump pulse are measured. We observe a bi-exponentially decaying signal with a fast time constant of 0.66 ps and a slower time constant of 2.8 ps. Both constants are independent of the pump fluence. By spatially and temporally resolving the differential reflection, we are able to observe a diffusion of excitons, and measure a diffusion coefficient of 200 cm2/s at room temperature and 300 cm2/s at lower temperatures of 10 K and 150 K.

description: The residual torsion-free nilpotence of the commutator subgroup of a knot group has played a key role in studying the bi-orderability of knot groups. A technique developed by Mayland provides a sufficient condition for the commutator subgroup of a knot group to be residually-torsion-free nilpotent using work of Baumslag. In this paper, we apply Mayland's technique to several genus one pretzel knots and a family of pretzel knots with arbitrarily high genus. As a result, we obtain a large number of new examples of knots with bi-orderable knot groups. These are the first examples of bi-orderable knot groups for knots which are not fibered or alternating.

description: We characterize 2-dimensional complexes associated canonically with basis graphs of matroids as simply connected triangle-square complexes satisfying some local conditions. This proves a version of a (disproved) conjecture by Stephen Maurer (Conjecture 3 of S. Maurer, Matroid basis graphs I, JCTB 14 (1973), 216-240). We also establish Conjecture 1 from the same paper about the redundancy of the conditions in the characterization of basis graphs. We indicate positive-curvature-like aspects of the local properties of the studied complexes. We characterize similarly the corresponding 2-dimensional complexes of even $Δ$-matroids.
