Are Revealed Intentions Possible?

This paper asks whether it is possible to design an Intentions Revealing Experiment – that is, an experiment in which the early moves of the decision maker in a dynamic decision problem reveal the intentions of that decision maker regarding later moves in the decision problem. If such a type of experiment is possible, then it will enable economists to test whether individuals have plans and implement them – a basic assumption of all economic theories of dynamic decision making. Unfortunately the main finding of the paper is in the form of two Impossibility Theorems which show that, unless one is prepared to make certain assumptions, such an Intentions Revealing Experiment is impossible. However, the paper does have a positive side – it describes the type of assumptions that one needs to make in order to make an Intentions Revealing Experiment possible.This paper asks whether it is possible to design an Intentions Revealing Experiment – that is, an experiment in which the early moves of the decision maker in a dynamic decision problem reveal the intentions of that decision maker regarding later moves in the decision problem.

Inferring Social Preferences over Income Distributions through Axioms

Numerous prior experimental studies have attempted to elicit people’s preferences over income distributions through appropriately incentivated questions asking subjects to choose between distributions. Instead, we follow the theoretical literature and start with the principles underlying these preferences. Such principles include, for example, the Rawlsian principle and the Lorenz principle. We implement possibly the first incentivated experiment concentrating solely and directly on these underlying principles. In essence, the experiment asks subjects to state their preferred principles, with the appropriate incentive being provided by the experimenter using the stated axioms to choose a preferred distribution from a randomly generated set, and this preferred distribution then being implemented on the participants in the experiment. Thus one of the subjects becomes the Social Planner. (We have two treatments, one in which the Social Planner is part of society and the second in which the Social Planner is outside society.) We solve problems implied when the chosen set of principle is either mutually contradictory or incomplete (by allowing sequential choice). We observe that the implied social preferences are different from those inferred indirectly through choice over distributions as in the earlier experimental studies, and that elicited preferences are different between the two treatments, suggesting that the disinterested Social Planner is more Equality-preferring than the Social Planner with self-interest.Numerous prior experimental studies have attempted to elicit people’s preferences over income distributions through appropriately incentivated questions asking subjects to choose between distributions.

On Choosing a Constitution (at least the part relating to the distribution of income)

A Constitution is a collection of principles or axioms determining how society should be organised, and a description of the ordering of the axioms in terms of their importance and of their invocation. We report on an experiment aimed at discovering preferred axioms relating to the distribution of income within society.A Constitution is a collection of principles or axioms determining how society should be organised, and a description of the ordering of the axioms in terms of their importance and of their invocation.

Architectural Challenges and Solutions for Collocated LWIP - A Network Layer Perspective

Achieving a tighter level of aggregation between LTE and Wi-Fi networks at the radio access network (a.k.a. LTE-Wi-Fi Aggregation or LWA) has become one of the most prominent solutions in the era of 5G to boost network capacit y and improve end user's quality of experience. LWA offers flexible resource scheduling decisions for steering user tr affic via LTE and Wi-Fi links. In this work, we propose a Collocated LTE/WLAN Radio Level Integration architecture at IP layer (C-LWIP), an enhancement over 3GPP non-collocated LWIP architecture. We have evaluated C-LWIP performance in vari ous link aggregation strategies (LASs). A C-LWIP node ( i.e. , the node having collocated, aggregated LTE eNodeB and Wi-Fi access point functionalities) is implemented in NS-3 which introd uces a traffic steering layer ( i.e. , Link Aggregation Layer) for efficient integration of LTE and Wi-Fi. Using extensive simulations, we verified the correctness of C-LWIP module in NS-3 and evaluat ed the aggregation benefits over standalone LTE and Wi-Fi netwo rks with respect to varying number of users and traffic types. We found that split bearer performs equivalently to switched b earer for UDP flows and switched bearer outperforms split bearer in the case of TCP flows. Also, we have enumerated the potential challenges to be addressed for unleashing C-LWIP capabilit ies. Our findings also include WoD-Link Aggregation Strategy whi ch is shown to improve system throughput by 50% as compared to Naive-LAS in a densely populated indoor stadium environmen t

Assessing Measurable Residual Disease in Chronic Myeloid Leukemia. BCR-ABL1 IS in the Avant-Garde of Molecular Hematology

Chronic myelogenous leukemia (CML) is a malignancy of the myeloid cell lineage characterized by a recurrent chromosomal abnormality: the Philadelphia chromosome, which results from the reciprocal translocation of the chromosomes 9 and 22. The Philadelphia chromosome contains a fusion gene called BCR-ABL1. The BCR-ABL1 codes for an aberrantly functioning tyrosine kinase that drives the malignant proliferation of the founding clone. The advent of tyrosine kinase inhibitors (TKI) represents a landmark in the treatment of CML, that has led to tremendous improvement in the remission and survival rates. Since the introduction of imatinib, the first TKI, several other TKI have been approved that further broadened the arsenal against CML. Patients treated with TKIs require sensitive monitoring of BCR-ABL1 transcripts with quantitative real-time polymerase chain reaction (qRT-PCT), which has become an essential part of managing patients with CML. In this review, we discuss the importance of the BCR-ABL1 assay, and we highlight the growing importance of BCR-ABL1 dynamics. We also introduce a mathematical correction for the BCR-ABL1 assay that could help homogenizing the use of the ABL1 as a control gene. Finally, we discuss the growing body of evidence concerning treatment-free remission. Along with the continuous improvement in the therapeutic arsenal against CML, the molecular monitoring of CML represents the avant-garde in the struggle to make CML a curable disease

Versatile regularisation toolkit for iterative image reconstruction with proximal splitting algorithms

Ill-posed image recovery requires regularisation to ensure stability. The presented open-source regularisation toolkit consists of state-of-the-art variational algorithms which can be embedded in a plug-and-play fashion into the general framework of proximal splitting methods. The packaged regularisers aim to satisfy various prior expectations of the investigated objects, e.g., their structural characteristics, smooth or non-smooth surface morphology. The flexibility of the toolkit helps with the design of more advanced model-based iterative reconstruction methods for different imaging modalities while operating with simpler building blocks. The toolkit is written for CPU and GPU architectures and wrapped for Python/MATLAB. We demonstrate the functionality of the toolkit in application to Positron Emission Tomography (PET) and X-ray synchrotron computed tomography (CT)

Fbxw7 Deletion Accelerates KrasG12D-Driven Pancreatic Tumorigenesis via Yap Accumulation

AbstractPancreatic cancers driven by KRAS mutations require additional mutations for tumor progression. The tumor suppressor FBXW7 is altered in pancreatic cancers, but its contribution to pancreatic tumorigenesis is unknown. To determine potential cooperation between Kras mutation and Fbxw7 inactivation in pancreatic tumorigenesis, we generated P48-Cre;LSL-KrasG12D;Fbxw7fl/fl (KFCfl/fl) compound mice. We found that KFCfl/fl mice displayed accelerated tumorigenesis: all mice succumbed to pancreatic ductal adenocarcinoma (PDA) by 40 days of age, with PDA onset occurring by 2 weeks of age. PDA in KFCfl/fl mice was preceded by earlier onset of acinar-to-ductal metaplasia (ADM) and pancreatic intraepithelial neoplasia (PanIN) lesions, and associated with chromosomal instability and the accumulation of Fbxw7 substrates Yes-associated protein (Yap), c-Myc, and Notch. Using KFCfl/fl and FBXW7-deficient human pancreatic cancer cells, we found that Yap silencing attenuated growth promotion by Fbxw7 deletion. Our data demonstrate that Fbxw7 is a potent suppressor of KrasG12D-induced pancreatic tumorigenesis due, at least in part, to negative regulation of Yap

Laser cleaning of gilded wood: a comparative study of colour variations induced by irradiation at different wavelengths

There is a growing interest by art conservators for laser cleaning of wood artworks, since traditional cleaning with chemical solvents can be a source of decay, due to the prolonged action of chemicals after the restoration. In this experiment we used excimer and Nd:YAGlasers, emitting radiation in the ultraviolet (248 nm), visible (532 nm) and near infrared (1064 nm), to investigate the effect of laser interaction on gilded wood samples at different wavelengths

Vibration issues in timber structures: A state-of-the-art review

The increasing use of timber structures worldwide has brought attention to the challenges posed by their lightweight nature, making them more prone to vibrations than more massive structures. Consequently, significant research efforts have been dedicated to understanding and mitigating vibrations in timber structures, while scientific committees strive to establish suitable design regulations. This study aims to classify and identify the main research themes related to timber structure vibrations and highlight future research needs and directions. A bibliometricbased selection process briefly introduces each research topic, presenting the latest findings and proposals for vibration design in timber structures. The paper emphasizes the key outcomes and significant contributions to understanding and addressing vibration issues in timber structures. These findings serve as valuable guidance for researchers, designers, and regulatory bodies involved in designing and assessing timber structures subjected to vibrations
