Plastic deformation mechanism of negative rake angle tools in low-speed cutting

Results in Engineering
Negative rake angle cutting can significantly enhance tool impact resistance and machining stability; however, the complexity of its plastic deformation mechanism hinders the optimization of tool geometry and cutting parameters.

Model predictive control with inline parameter adaptation for direct crystal growth rate regulation

AIChE Journal, EarlyView.
Abstract In batch cooling crystallization, many interactive factors, including supersaturation, reactor dimensions, and operating conditions, govern crystal growth and significantly influence product properties. Variables such as temperature or refractive index are used as surrogate control variables but have limitations in capturing growth rate ...

A Rare Form of Microcephalic Primordial Dwarfism due to NSMCE2 Deficiency (Seckel Syndrome Type 10): A Report of Macular Involvement

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic variants in NSMCE2 (MMS21), which encodes the SUMO E3 ligase subunit of the SMC5/6 chromatin‐maintenance complex, have recently been implicated in microcephalic primordial dwarfism (MPD), corresponding to Seckel syndrome type 10 (OMIM #617246).

Study on chip removal mechanism of PCD ball-end milling (1st report) cutting simulation by orthogonal cutting

Production and Manufacturing Research: An Open Access Journal, 2020
A polycrystalline diamond (PCD) ball-end mill is effective for processing molds made of hard and brittle materials, such as cemented carbide and ceramics and having fine and complex shapes with a high aspect ratio. The PCD ball-end mill has a distinctive

Cable Reinforcement Combined With Biologic Tuberoplasty Restores Muscle Forces and Scapular Strain in an Irreparable Rotator Cuff Tear Model: A Cadaveric Study

Arthroscopy, EarlyView.
Purpose To investigate the biomechanical impact of an irreparable rotator cuff tear and compare the isolated and combined effects of rotator cable reconstruction (CR) and biologic tuberoplasty (BioTB). Methods Eight cadaveric shoulders were tested using an ex vivo dynamic shoulder simulator in forward flexion (FF) and scapular plane abduction (SPA ...

Environmental, Social, and Governance Information Disclosure: Who Discloses Wins?

Business Strategy and the Environment, EarlyView.
ABSTRACT As Environmental, Social, and Governance (ESG) Information Disclosure (ESG‐ID) transitions from voluntary to mandatory disclosure, its drivers and impacts have become focal points of discussion. Existing research, however, lacks integration, which, in turn, has led to fragmented theoretical and practical insights.

Assessing the effect of DS-CDMA chip rate on RAKE branch statistics using a ray-tracing propagation model [PDF]

, 1994
An important improvement in the performance of CDMA and other wideband digital communication systems can be achieved using a RAKE receiver architecture and diversity combining of its branches. The paper presents an analysis of RAKE branch statistics as a

Lasso for hierarchical polynomial models

Canadian Journal of Statistics, EarlyView.
Abstract The divisibility conditions implicit in a polynomial hierarchy suggest parameter constraints in regression. With this idea, we establish strong and weak hierarchies for both the lasso and relaxed lasso. Our proposal extends prior work on hierarchical lasso, which was mainly concerned with models of degree 2.
