Digital Transformation and Corporate Financial Asset Allocation: Evidence from China
Against the backdrop of rapid technological advancement and the deepening digital economy, this study examines the causal impact of digital transformation on corporate financial asset allocation in China. Using data from A-share listed companies from 2010 to 2022, we construct a firm-level digitalization index based on text analysis of annual reports and differentiate financial asset allocation into long-term and short-term dimensions. Employing fixed-effects models and a staggered difference-i…

BTW - that CBC article used a lot of numbers from this report, which because it's all numbers is awesome. Some tidbits:
- The number of farms over 3,500 acres has nearly doubled in 20 years.
- 41.3% of Canadian farmland is rented.
- From 1971 to 2021, the farm population declined by 62.2%, from 1 in 14 Canadians to 1 in 61.
- Farm debt has more than doubled in the last 20 years, from $43B in 2002 to $138.8B in 2022. That is currently 10x the size of net farm income.
- In 2021, 96,043 tonnes of pesticides were sold for agricultural use – more than three times the amount sold in 1991.

Investigating Document Type, Language, Publication Year, and Author Count Discrepancies Between OpenAlex and Web of Science
Bibliometrics, whether used for research or research evaluation, relies on large multidisciplinary databases of research outputs and citation indices. The Web of Science (WoS) was the main supporting infrastructure of the field for more than 30 years until several new competitors emerged. OpenAlex, a bibliographic database launched in 2022, has distinguished itself for its openness and extensive coverage. While OpenAlex may reduce or eliminate barriers to accessing bibliometric data, one of the…

Its clear that Trump is effectively if not literally a Russian agent hell bent on destroying the USA...
"As president of the Massachusetts AFL-CIO Chrissy Lynch said in July after the Republicans passed the budget reconciliation bill cutting clean energy tax credits: “Working families shouldn’t have to purchase energy from billionaire oil tycoons and foreign governments or let them set the price of our energy bills.”
Her observation hit home earlier this week, when Joe Wallace, Costas Paris, Alex Leary, and Collin Eaton of the Wall Street Journal reported that the comments of Russian president Vladimir Putin and Trump at their meeting in Alaska on August 15 in which they talked about doing more business together were not vague goodwill. ExxonMobil and Russia’s biggest energy company, Rosneft, have been in secret talks to resume a partnership to extract Russian oil, including in the Arctic, that had been severed by Russia’s attack on Ukraine in 2022."

Linearly involved Generalized Moreau Enhanced Model with Non-quadratic Smooth Convex Data Fidelity Functions
In this paper, we introduce an overall convex model incorporating a nonconvex regularizer. The proposed model is designed by extending the least squares term in the constrained LiGME model [Yata Yamagishi Yamada 2022] to fairly general smooth convex functions for flexible utilization of non-quadratic data fidelity functions. Under an overall convexity condition for the proposed model, we present sufficient conditions for the existence of a minimizer of the proposed model and an inner-loop free …

Thickness-dependent magnon spin transport in antiferromagnetic insulators: Crossover from quasi-three-dimensional to quasi-two-dimensional regimes
Motivated by the recent observation of giant room-temperature magnon spin conductivity in an ultrathin ferromagnetic insulator [X.-Y. Wei et al., Nat. Mater. 21, 1352 (2022)], we investigate thickness-dependent magnon spin transport in thin antiferromagnetic insulators (AFIs). We study the prototypical AFI hematite, known for its exceptionally low magnetic damping and two distinct magnetic phases: a low-temperature uniaxial easy-axis phase and a high-temperature biaxial easy-plane phase.

We investigate semantic networks of achievement standards for physics subjects in the 2022 revised curriculum to derive information embedded in the curriculum. We extract each subject's keywords with node strength and random-walk betweenness, detect communities of physics terms by the optimized greedy algorithm, and find the connectivity of physics subjects using bipartite networks. The network analysis reveals three remarkable results: First, keywords are about scientific thinking and practice…

The neutron star X-ray transient MAXI J1807+132 has undergone outbursts in 2017, 2019, and 2023. We conducted an $R$-band time series photometry campaign using the Isaac Newton Telescope during the 2022 quiescent state. We detected a periodic variation in the light curve, consistent with ellipsoidal modulation, which allowed us to determine an orbital period of $P_{\rm orb} = 4.258 \pm 0.008$ hr. By modelling the light curve, we obtained a binary inclination of $ i = 72\pm5 \, °$ and a mass ra…

We present analytic fits of classical one--component plasma (OCP) internal energy over a wide range of coupling parameter $0.01\leΓ\le 170$ using Monte--Carlo data in the thermodynamic limit. We extend the dataset obtained in [Demyanov and Levashov, Phys. Rev. E 106, 015204 (2022)] using the angular--averaged Ewald potential with additional points at strong coupling ($Γ=120,\ 150,\ 170$). We then fit two frequently used functional forms for the OCP equation of state: (i) a five-parameter equa…

Effective source for second-order self-force calculations: quasicircular orbits in Schwarzschild spacetime
Recent years have seen the first production of "post-adiabatic" gravitational-waveform models based on second-order gravitational self-force theory. These models rely on calculations of an effective source in the perturbative second-order Einstein equation. Here, for the first time, we detail the calculation of the effective source in a Schwarzschild background, which underlies the second-order self-force results in [Phys. Rev. Lett. 127, 151102 (2021); ibid. 128, 231101 (2022); ibid. 130, 2414…

Large maximal subgroups of almost simple classical groups
A proper subgroup $H$ in a finite group $G$ is said to be large if $|H|^3\geq |G|$. In this paper, we determined all large maximal subgroups of almost simple classical groups. Combined with the work of Alavi and Burness (J. Algebra 421 (2015) 187--233) and Alavi, Bayat, and Daneshkhah (J. Algebraic Combin. 55 (2022) 729--779), this completes the classification of all large maximal subgroups of almost simple groups.

Projected branes as platforms for crystalline, superconducting, and higher-order topological phases
Projected branes are constituted by only a small subset of sites of a higher-dimensional crystal, otherwise placed on a hyperplane oriented at an irrational or a rational slope therein, for which the effective Hamiltonian is constructed by systematically integrating out the sites of the parent lattice that fall outside such branes [Commun. Phys. 5, 230 (2022)]. Specifically, when such a brane is constructed from a square lattice, it gives rise to an aperiodic Fibonacci quasi-crystal or its rati…
