    Abstract Osteoporotic vertebral fractures (OVFs) are a significant health concern linked to increased morbidity, mortality, and diminished quality of life. Traditional OVF risk assessment tools like bone mineral density (BMD) only capture a fraction of the risk profile. Artificial intelligence, specifically computer vision, has revolutionized other fields of medicine through analysis of videos, histopathology slides and radiological scans. In this review, we provide an overview of computer vision algorithms and current computer vision models used in predicting OVF risk. We highlight the clinical applications, future directions and limitations of computer vision in OVF risk prediction.

    Abstract Background: Studies suggest that there are key differences in operative experience based on a trainee's gender. A large-scale self-efficacy (SE) survey, distributed to general surgery residents after the American Board of Surgery In-Training Examination in 2020, found that female gender was associated with decreased SE in graduating PGY5 residents for all 4 laparoscopic procedures included on the survey (cholecystectomy, appendectomy, right hemicolectomy, and diagnostic laparoscopy). We sought to determine whether these differences were reflected at the case level when considering operative performance and supervision using an operative assessment tool (SIMPL OR).
    Methods: Supervision and performance data reported through the SIMPL OR platform for the same 4 laparoscopic procedures included in the SE survey were aggregated for residents who were PGY5s in 2020. Independent t-tests and multiple linear regression were used to determine the relationship between trainee gender and supervision/performance ratings.
    Results: For laparoscopic cases in aggregate (n = 2708), male residents rated their performance higher than females (3.57 vs. 3.26, p < 0.001, 1 = critical deficiency, 5 = exceptional performance) and reported less supervision (3.15 vs. 2.85, p < 0.001, 1 = show and tell, 4 = supervision only); similar findings were seen when looking at attending reports of resident supervision and performance. A multiple linear regression model showed that attending gender did not significantly predict resident-reported supervision or performance levels, while case complexity and trainee gender significantly affected both supervision and performance (p < 0.001).
    Discussion: Female residents perceive themselves to be less self-efficacious at core laparoscopic procedures compared to their male colleagues. Comparison to more case-specific data confirm that female residents receive more supervision and lower performance ratings. This may create a domino effect in which female residents receive less operative independence, preventing the opportunity to establish SE. Further research should identify opportunities to break this cycle and consider gender identity beyond the male/female construct.

  6. Book ; Online: Anisotropic Effect of Dipolar Interaction in Ordered Ensembles of Nanoparticles

    Abstract: ... The coercive field $\mu^{}_oH^{}_c$, remanent magnetization $M^{}_r$, and the heat dissipation $E^{}_H$ also ... irrespective of $A^{}_r$, $\alpha$, and the field directions.

    Abstract We implement extensive computer simulations to investigate the hysteresis characteristics in the ordered arrays ($l^{}_x\times l^{}_y$) of magnetic nanoparticles as a function of aspect ratio $A^{}_r=l^{}_y/l^{}_x$, dipolar interaction strength $h^{}_d$, and external magnetic field directions. We have considered the aligned anisotropy case, $\alpha$ is the orientational angle. It provides an elegant en route to unearth the explicit role of anisotropy and dipolar interaction on the hysteresis response in such a versatile system. The superparamagnetic character is dominant with weak dipolar interaction ($h^{}_d\leq0.2$), resulting in the minimal hysteresis loop area. Remarkably, the double-loop hysteresis emerges even with moderate interaction strength ($h^{}_d\approx0.4$), reminiscent of antiferromagnetic coupling. These features are strongly dependent on $\alpha$ and $A^{}_r$. Interestingly, the hysteresis loop area increases with $h^{}_d$, provided $A^{}_r$ is enormous, and the external magnetic field is along the $y$-direction. The coercive field $\mu^{}_oH^{}_c$, remanent magnetization $M^{}_r$, and the heat dissipation $E^{}_H$ also depend strongly on these parameters. Irrespective of the external field direction and weak dipolar interaction ($h^{}_d\leq0.4$), there is an increase in $\mu^{}_oH^{}_c$ with $h^{}_d$ for a fixed $\alpha$ and $A^{}_r\leq4.0$. The dipolar interaction also elevates $M^{}_r$ as long as $A^{}_r$ is huge and the field is along the $y$-direction. $E^{}_H$ is minimal for negligible and weak dipolar interaction, irrespective of $A^{}_r$, $\alpha$, and the field directions. Notably, the magnetic interaction enhances $E^{}_H$ if $A^{}_r$ is enormous and the magnetic field is along the long axis of the system. These results are beneficial in various applications of interest such as digital data storage, spintronics, etc.

  7. Book ; Online: Hysteresis in Two Dimensional Arrays of Magnetic Nanoparticles

    Abstract: ... temperature $T$, aspect ratio $A^{}_r=L^{}_y/L^{}_x$, and the applied alternating magnetic field's direction ... of antiferromagnetic interaction dominance for $A^{}_r\leq6$ and considerable dipolar interaction strength ($h^{}_d>0.2 ... the hysteresis for large $h^{}_d$ and $A^{}_r>6$.

    Abstract We perform computer simulations to probe the magnetic hysteresis in a two-dimensional ($L^{}_x\times L^{}_y$) assembly of magnetic nanoparticles as a function of dipolar interaction strength $h^{}_d$, temperature $T$, aspect ratio $A^{}_r=L^{}_y/L^{}_x$, and the applied alternating magnetic field's direction. In the absence of magnetic interaction ($h^{}_d\approx0$) and thermal fluctuations ($T=0$ K), the hysteresis follows the Stoner and Wohlfarth model, as expected. For weak dipolar interaction and substantial temperature, the hysteresis has the dominance of superparamagnetic behaviour, irrespective of the applied magnetic field's direction and $A^{}_r$. Interestingly, the hysteresis curve has all the characteristics of antiferromagnetic interaction dominance for $A^{}_r\leq6$ and considerable dipolar interaction strength ($h^{}_d>0.2)$, which is independent of applied magnetic direction. When the magnetic field is applied along the system's shorter axis ($x$-direction), a non-hysteresis straight line is observed with large $h^{}_d$. In the case of the magnetic field applied along the long axis of the sample ($y$-direction), ferromagnetic interaction dominates the hysteresis for large $h^{}_d$ and $A^{}_r>6$. Irrespective of $h^{}_d$ and applied magnetic field's direction, the coercive field $\mu^{}_oH^{}_c$ and remanence $M^{}_r$ are minimal for $A^{}_r\leq6$ and significant temperature. They are found to increase with $h^{}_d$ when $A^{}_r$ is enormous. Remarkably, the variation of hysteresis loop area $E^{}_H$ as a function of these parameters is the same as that of the coercive field variation. We believe that the concepts presented in this work are relevant in various technological applications such as spintronics and magnetic hyperthermia, in which such self-assembled nanoparticle arrays are ubiquitous.

    Abstract We study the ground state and magnetic hysteresis properties of 2$d$ arrays ($L^{}_x\times L^{}_y$) of dipolar interacting magnetic nanoparticles (MNPs) by performing micromagnetic simulations. Our primary interest is to understand the effect of sample shape, $\Theta$- the ratio of the dipolar strength to the anisotropy strength, and the direction of the applied field $\vec{H} = H_{o}\hat{e}^{}_H$ on the ground state and the magnetic hysteresis in an array of MNPs. To study the effect of shape of the sample, we have varied the aspect ratio $A^{}_r=L^{}_y/L^{}_x$ which in turn, is found to induce shape anisotropy in the system. Our main observations are: (a) When the dipolar interaction is strong $(\Theta>1)$, the ground state morphology has in-plane ordering of magnetic moments. (b) The ground state morphology has randomly oriented magnetic moments which is robust with respect to system sizes and $A^{}_r$ for weakly interacting MNPs ($\Theta<1$). (c) Micromagnetic simulations suggests that the dipolar interaction decreases the coercive field $H^{}_c$. (d) The remanence magnetization $M^{}_r$ is found to be strongly dependent not only on the strength of dipolar interaction but also on the shape of the sample. (e) Due to anisotropic nature of dipolar interaction, a strong effect of shape anisotropy is observed when the field is applied along longer axis of the sample. The dipolar interaction in such a case induces an effective ferromagnetic coupling when the aspect ratio is very large. These results are of vital importance in high-density recording systems, magneto-impedance sensors, etc.

    Abstract We investigate the dependence of magnetic properties on the out-of-plane disorder strength $\Delta$, dipolar interaction strength $h^{}_d$ in two-dimensional ($l^{}_x\times l^{}_y$) ensembles of nanoparticles using numerical simulations. Such positional defects are redundantly observed in experiments. The superparamagnetic character is dominant with negligible and weak interaction strength $h^{}_d$, irrespective of $\Delta$ and aspect ratio of the system $A^{}_r=l^{}_y/l^{}_x$. The double-loop hysteresis curve, characteristics of antiferromagnetic coupling dominance, emerges with large $h^{}_d$ and $\Delta(\%)\leq5$ in the square-like nanoparticles' assays. Remarkably, the dipolar interaction of sufficient strength drives the magnetic order from antiferromagnetic to ferromagnetic with large $\Delta$ and $A^{}_r\leq4.0$, resulting in an enhancement in the hysteresis loop area. On the other hand, the ferromagnetic coupling gets increased with $h^{}_d$ in systems with huge $A^{}_r$. Consequently, the hysteresis loop is enormous, even with moderate $h^{}_d$. The variation of the coercive field $\mu^{}_oH^{}_c$, remanence $M^{}_r$, and amount of heat released $E^{}_H$ (due to the hysteresis) with these parameters also suggests the transformation of nature dipolar interaction. They are significant even with large $h^{}_d$ and smaller $A^{}_r$, indicating the antiferromagnetic coupling dominance. Interestingly, there is an enhancement in these with $\Delta$ and large $h^{}_d$ due to ferromagnetic interaction. Notably, they are very significant even with moderate $h^{}_d$ in the highly anisotropic system and external field along the long axis of the sample. These results could help the experimentalist in explaining the unusual hysteresis characteristics observed in such systems and should also be beneficial in diverse applications such as data storage, magnetic hyperthermia, etc.

    Abstract Scaling up invariably error-prone quantum processors is a formidable challenge. Although quantum error correction ultimately promises fault-tolerant operation, the required qubit overhead and error thresholds are daunting. In a complementary proposal, colocated, auxiliary "spectator" qubits act as in situ probes of noise and enable real-time, coherent corrections of data qubit errors. We used an array of cesium spectator qubits to correct correlated phase errors on an array of rubidium data qubits. By combining in-sequence readout, data processing, and feedforward operations, these correlated errors were suppressed within the execution of the quantum circuit. The protocol is broadly applicable to quantum information platforms and establishes key tools for scaling neutral-atom quantum processors: mid-circuit readout of atom arrays, real-time processing and feedforward, and coherent mid-circuit reloading of atomic qubits.
