Can Cryptocurrency Enable a Stateless, Global Economy?
When Bitcoin was released to the world in 2008 it was celebrated as a pivotal moment in technology and cryptography. It opened our eyes to the possibility of a path forward for society in terms of a global financial system free from the incumbent systems, liberating money from the clutches of the state by offering a transparent, permissionless alternative. Like many early adopters I was swept up in the excitement. The vision of a world with a fair and global peer-to-peer economy excited me as I imagined the power this would unlock for both individuals and organizations without influence by state actors who are more and more disconnected from the plight of their own communities. Today the path we’ve chosen has taken a sharp turn away from the original vision and values from which it spawned.

Revisiting Discrepancies in Diffusion Theory: Preliminary Material
(1) K. Razi Naqvi, Department of Physics, Norwegian University of Science and Technology (NTNU), 7094 Trondheim, Norway. 2.1 Statement of the Milne problem and terminology. A homogeneous, semi-infinite, non-absorbing medium occupies the half-space 𝑥 > 0, and sustains a constant current of test particles in the negative 𝑥 direction. The medium (or the host) itself contains no sources or sinks, and the plane boundary at 𝑥 = 0 acts as a black wall that absorbs all particles incident on it. The test particles obey either the one-speed LorentzBoltzmann equation (LBE) of neutron transport or radiative transfer, in which case one is faced with the Milne problem, or the Klein-Kramers equation (KKE), which leads one to the Brownian analog of the Milne problem. The problem is to determine 𝑛(𝑥), the density of the particles inside the medium (𝑥 > 0).
Can You Still Phone It In? The Challenges of Managing Remote Workers
The COVID-19 pandemic may be behind us, but its effects are still felt, especially in the workplace. Between 2019 and 2023, 40% of U.S. employees started working from home at least one day per week. Sustaining a remote workforce has become a necessity. Supporting a remote and hybrid workforce presents new leadership challenges, particularly now that organizations are moving workers back to the office.
Theory Coherent Shrinkage of Time Varying Parameters in VARs: Theory coherent TVP-VAR
Andrea Renzetti, Department of Economics, Alma Mater Studiorium Universit`a di Bologna, Piazza Scaravilli 2, 40126 Bologna, Italy. The construction of a theory coherent prior builds on the idea that an economic theory implies restrictions on the parameters of the TVP-VAR. Intuitively we can find out these restrictions by specifying a prior distribution on the deep parameters from the theory, simulating the data from the theory and then estimating a TVP-VAR on the simulated data. Imposing a prior on the deep parameters from the theory will then induce a prior on the parameters of the TVP-VAR encoding the restrictions imposed by the economic theory. Based on this idea, in this section I derive analytically a prior for a TVP-VAR which is theory coherent, in the sense that it centers the time varying coefficients on the cross equation restrictions implied by an underlying economic theory about the variables in the system.
How Ricky Zhang Is Pioneering the Hybrid Role of Design Engineering
Beautiful products that actually work well—not too much to ask is it? You’d think so, but tech companies have struggled for years to nail this seemingly simple concept. On the one hand, it is a sleek product that attracts customers with its appearance. Users love its stunning design, but after a few days, complaints about crashes and sluggish performance flood in. Meanwhile, across town, an engineering marvel of an app works flawlessly, but its clunky interface confounds users.
Revisiting Discrepancies in Diffusion Theory: Concluding Remarks and References
(1) K. Razi Naqvi, Department of Physics, Norwegian University of Science and Technology (NTNU), 7094 Trondheim, Norway. The claim—motivated by the search for a better boundary condition—that the Lorentz model is a useful tool for investigating bimolecular reactions in solutions became credible only after the publication of Burschka and Titulaer’s numerical solution of the one-dimensional KKE [4]. Immediately prior to that, one critic expressed the “community opinion” by stating in a referee report (on an article co-authored by me) that the LBE “is absolutely useless in dealing with transport in liquids”, and insisted that this task is best handled by solving the KKE. Only then did the need arise for comparing the length scales of inverse and regular Brownian motion. The Trondheim group has shown that inverse Brownian motion, regular Brownian motion and the BGK-model are indistinguishable at the DE-level, provided that one uses the appropriate BC [31], namely that stated in Eq. (20). A Procrustean random walk model that allows no distribution of path lengths seems (to me) unphysical, much like the lattice model that informed Smoluchowksi’s thinking (about the boundary condition at an absorbing surface), and has misinformed generations of students as well as aficionados of chemical kinetics.

Revisiting Discrepancies in Diffusion Theory: Molecular Motion in Liquids
(1) K. Razi Naqvi, Department of Physics, Norwegian University of Science and Technology (NTNU), 7094 Trondheim, Norway. One of the most important and keenly controverted issues dicussed by Hildebrand in his thoughtful and purposely provocative note is the question whether concepts borrowed from the kinetic theory of gases or classical hydrodynamics can be legitimately applied to describe solute diffusion in liquid [30]. The bulk of his criticism is to be found in the last two paragraphs, excerpts from which appear below:
Revisiting Discrepancies in Diffusion Theory: Abstract and Introduction
(1) K. Razi Naqvi, Department of Physics, Norwegian University of Science and Technology (NTNU), 7094 Trondheim, Norway. In a paper on “the Brownian motion analog of the well-known Milne problem in radiative transfer theory” [J Stat Phys 25 (1981) 569–82], Burschka and Titulaer reported: “The value we find for this ‘Milne extrapolation length’ is, in the appropriate dimensionless units, approximately twice the value found in the radiative transfer problem.” A study by Ziff [J Stat Phys 65 (1991) 1217–33], concerned with the absorption of particles executing a Rayleigh flight (randomly directed displacements of equal length 𝑙) by a black sphere of radius 𝑅, led to a value for the extrapolation length 𝛾 about half as small as the benchmark result (for 𝑅 ≫ 𝑙). The first discrepancy is shown to result from the disparity of the two length scales; the second, from the zero variance of the jump lengths. Ziff’s finding that 𝛾 is independent of 𝑅 for 0 < 𝑙 ≤ 2𝑅, cannot be reconciled with studies based on the Lorentz-Boltzmann equation and the Klein-Kramers equation.
Theory Coherent Shrinkage of Time Varying Parameters in VARs: Abstract and Introduction
Andrea Renzetti, Department of Economics, Alma Mater Studiorium Universit`a di Bologna, Piazza Scaravilli 2, 40126 Bologna, Italy. Time-varying parameters Vector Autoregressive (TVP-VAR) models are frequently used in economics to capture evolving relationships among the macroeconomic variables. However, TVP-VARs have the tendency of overfitting the data, resulting in inaccurate forecasts and imprecise estimates of typical objects of interests such as the impulse response functions. This paper introduces a Theory Coherent Time-Varying Parameters Vector Autoregressive Model (TC-TVP-VAR), which leverages on an arbitrary theoretical framework derived by an underlying economic theory to form a prior for the time varying parameters. This “theory coherent” shrinkage prior significantly improves inference precision and forecast accuracy over the standard TVP-VAR. Furthermore, the TC-TVP-VAR can be used to perform indirect posterior inference on the deep parameters of the underlying economic theory. The paper reveals that using the classical 3-equation New Keynesian block to form a prior for the TVPVAR substantially enhances forecast accuracy of output growth and of the inflation rate in a standard model of monetary policy. Additionally, the paper shows that the TC-TVP-VAR can be used to address the inferential challenges during the Zero Lower Bound (ZLB) period.

Revisiting Discrepancies in Diffusion Theory: Flux to a Spherical Trap
(1) K. Razi Naqvi, Department of Physics, Norwegian University of Science and Technology (NTNU), 7094 Trondheim, Norway. For absorption of R-particles by a spherical trap of radius 𝑅, Ziff found the “Milne extrapolation length” to be ≈ 0.29795219𝑙 for 0 < 𝑙 ≤ 2𝑅. Since this result contradicts (at least at first sight) a great deal of work on closely related problems, including some carried out by the present author, and no resolution was offered in Ziff’s paper [20], or in two of its sparkling sequels [21, 22], a probe into the discrepancy is warranted.
