High volume computational histopathology 3Scan3Scan
Light microscopy is the gold standard for investigating microscopic structures and
pathological alterations in both human and animal models of disease. However, due
to tedious manual interventions, quantification of histopathologic markers is
classically performed on only a few 2D tissue sections, thus restricting
measurements and observations to limited portions of the sample volume.
Understanding vascular networks within tissues is a critical component to identifying pathophysiology. The work presented here introduces a methodology for multi-parametric quantification of vascular networks for whole-mount tissues. Our approach streamlines the histopathology workflow, enables observations within large 3D sample volumes, and provides opportunities for automated image analysis.

Abstract
Terahertz spectral analysis has been conducted on epitaxially grown semiconductor structures. Epitaxially grown semiconductors are important for microelectronic and optoelectronic devices and also for integrated circuits
fabricated using semiconductors. In this paper, we report results of terahertz time-domain spectroscopy of grown
SiGe layers on Ge buffer and separately a Ge buffer that was grown on a Si <001> wafer. In particular, evolution of
the time-domain spectra as a function of thickness of both samples was investigated by the terahertz pump-probe
technique. Representative spectra were analyzed to determine the respective layers’ spectral signatures. It was found that the spectroscopic analysis uniquely identified different layers by characteristic absorbance peaks. In addition, terahertz imaging was conducted in a non-destructive, non-contact mode for detecting lattice stacking fault and dislocations. Sub-surface imaging of grown SiGe layers on Ge buffer and that of the Ge buffer grown on a Si wafer reveals interesting lattice features in both samples. A comparison with TEM images of the samples exhibits that the terahertz image reproduces the dimensions found from TEM images within the experimental error limits. In particular, 3D images of both samples were generated by the terahertz reconstructive technique. The images were analyzed by graphical means to determine the respective layer thicknesses. Thus, this technique offers a versatile tool for both semiconductor research and in-line inspections.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

3. Grain size is a fundamental physical property of sedimentary rocks and, as
such, is a useful descriptive property.
Grain size affects the porosity and permeability and porosity of the rocks
and thus is of considerable interest to petroleum geologists.
Grain size data reflects sedimentation mechanisms, transportation and
depositional conditions
Importance Of Grain Size Data
5. This method is used to measure unconsolidated
sediments by sieving them through a set of nested wire mesh screens.
Particles having size smaller than the mesh pass through while the smaller
ones remain.
Size of mesh is standardized and is identified using mesh number.
The mesh number denotes the number of squares present in 1sq.inch of
area
Sieve Analysis

7. The settling velocity of particles falling through a fluid medium depends on the
size, shape, and density of the particle, and the density and viscosity of the fluid.
In this technique, grains are allowed to settle through a column of water at a
specified temperature in a settling tube. It is based on Stoke’s law:
where;
V= settling velocity
C= constant
D= diameter of the particle
Settling Tube Analysis
8. A laser-diffractor size analyzer operates on the principle that particles of a given size
diffract light through a given angle, which increase with decreasing particle size.
This technique use T.V cameras to capture and digitize grain images from which, with the
aid of appropriate computer software, grain size diameters can be calculated.
A photohydrometer is a settling tube that relates the changes in the intensity of the beam
of light passed through a column of suspended sediment to particles settling velocities
and thus to particle size
