Polar Topographic Derivatives for 3D Face Recognition: Application to Internet of Things Security [PDF]
We propose Polar Topographic Derivatives (PTD) to fuse the shape and texture information of a facial surface for 3D face recognition. Polar Average Absolute Deviations (PAADs) of the Gabor topography maps are extracted as features.

Efficient mechanochemical synthesis of regioselective persubstituted cyclodextrins
A number of per-6-substituted cyclodextrin derivative syntheses have been effectively carried out in a planetary ball mill under solvent-free conditions.

Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

On Bernstein and Turán-type integral mean estimates for polar derivative of a polynomial
Let p ( z ) $p(z)$ be a polynomial of degree n having no zero in | z | < k $|z|< k$ , k ≤ 1 $k\leq 1$ , then Govil [Proc. Nat. Acad. Sci., 50(1980), 50-52] proved max | z | = 1 | p ′ ( z ) | ≤ n 1 + k n max | z | = 1 | p ( z ) | , $$ \max _{|z|=1}|p'(z)|\

Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Towards sympathetic cooling of large molecules: Cold collisions between benzene and rare gas atoms [PDF]
This paper reports on calculations of collisional cross sections for the complexes Z-CDH6 (X = 3He, 4He, Ne) at temperatures in the range 1)μK - 10K and shows that relatively large cross sections in the 103-105Å2 range are available for collisional ...

Phthalate Derivative from the Non-Polar Fraction of Andaliman (Zathoxylum acanthopodium DC.) Stem Wood from North Sumatra [PDF]
Andaliman (Z. acanthopodium DC.), a plant belonging to the Zanthoxylum genus, is widely found in North Sumatra. Z. acanthopodium DC. has been traditionally used by local people to treat various diseases.

Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

An Exploratory Analysis Of Experimental Polar Tensor Data [PDF]
An exploratory statistical study of 157 atomic polar tensors (APT's) taken from 50 molecules is reported. Correlations for all five APT invariants show that comparisons of APT's for different molecules can be made by using mean dipole moment derivative ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
