The extensive feedback that students left at the end of courses can be very helpful in enhancing and honing the instruction. The comments, expressed in text format, cannot be effectively represented in a way that the computer can recognize, and the meaning implied in the comments is always blurry, making it more difficult for the computer to understand them. As a result, it is challenging for the computer to use these comments and comprehend student appeal. In this paper, we address the representation problem by projecting comments (including words) into a dense vector space. We suggest using a highly deep neural network to capture the textual meaning while examining a real-world dataset of five-year comments from end-of-course evaluations at a university. The suggested model is assessed based on its capacity to identify the sentimental inclinations of these remarks, yielding insightful recommendations and critiques.

Threshold variants of the Schnorr signature scheme have recently been at the center of attention due to their applications to cryptocurrencies. However, existing constructions for threshold Schnorr signatures among a set of n parties with corruption threshold tc suffer from at least one of the following drawbacks: (i) security only against static (i.e., non-adaptive) adversaries, (ii) cubic or higher communication cost to generate a single signature, (iii) strong synchrony assumptions on the network, or (iv) t(c) + 1 are sufficient to generate a signature, i.e., the corruption threshold of the scheme equals its reconstruction threshold. Especially (iv) turns out to be a severe limitation for many asynchronous realworld applications where t(c) < n/3 is necessary to maintain liveness, but a higher signing threshold of n - t(c) is needed. A recent scheme, ROAST, proposed by Ruffing et al. (ACM CCS '22) addresses (iii) and (iv), but still falls short of obtaining subcubic complexity and adaptive security. In this work, we present HARTS, the first threshold Schnorr signature scheme to incorporate all these desiderata. More concretely: - HARTS is adaptively secure and remains fully secure and operational even under asynchronous network conditions in the presence of up to t(c) < n/3 malicious parties. This is optimal. - HARTS outputs a Schnorr signature of size lambda with a near-optimal amortized communication cost of O(lambda n(2) log n) bits and a single online round per signature. - HARTS is a high-threshold scheme: no fewer than t(r) + 1 signature shares can be combined to yield a full signature, where any t(r) is an element of[t(c), n-t(c)) is supported. This especially covers the case t(r) >= 2n/3 > 2t(c). This is optimal. We prove our result in a modular fashion in the algebraic group model. At the core of our construction, we design a new simple and adaptively secure high-threshold asynchronous verifiable secret sharing (AVSS) scheme which may be of independent in

Stereoscopic observation is a common foundation of medical image analysis and is generally achieved by 3D medical imaging based on settled scanners, such as CT and MRI, that are not as convenient as X-ray machines in some flexible scenarios. However, X-ray images can only provide perspective 2D observation and lack view in the third dimension. If 3D information can be deduced from X-ray images, it would broaden the application of X-ray machines. Focus on the above objective, this paper dedicates to the generation of pseudo 3D CT scans from non-parallel 2D perspective X-ray (PXR) views and proposes the Draw Sketch and Draw Flesh (DSDF) framework to first roughly predict the tissue distribution (Sketch) from PXR views and then render the tissue details (Flesh) from the tissue distribution and PXR views. Different from previous studies that focus only on partial locations, e.g., chest or neck, this study theoretically investigates the feasibility of head-to-leg reconstruction, i.e., generally applicable to any body parts. Experiments on 559 whole-body samples from 4 cohorts suggest that our DSDF can reconstruct more reasonable pseudo CT images than state-of-the-art methods and achieve promising results in both visualization and various downstream tasks.
