Multi-Product Quantity Discount
Authors: Liu Zuofeng 
Published: February 2023

Abstract

For products with different quantity discount strategies, the seller needs to manually unify the products’ discount strategies for a multi-product quantity discount. In addition, the quantity discount in current practice often fails to give reasonable quantity discounts for multiple products. Is it possible to develop an algorithm to automatically and efficiently provide more reasonable multi-product quantity discounts while keeping each product's quantity discount strategy unchanged? This is what the authors achieved via a brand-new approach in this paper. According to the nature of quantity discount, the quantity of products should have a consistent logic with the products' prices, that is the more purchases, the higher the total discount price and the higher discount on each product that does not reach its maximum discount. And it can be assumed that the traditional discrete quantity discount should also follow this nature, it is just due to no algorithm support or the interest consideration that sellers follow the nature only on discrete discount thresholds and adopt traditional results on the other quantities. Along this line of thought, the authors define for the first time the multi-product quantity discount that can be applied to multiple products with different discount strategies, and use the rigorous mathematical method to complete the development of the algorithm which supports the continuous quantity discount and the discrete quantity discount that cover the traditional discrete quantity discount.
Dynamic modulation of synaptic transmission in the mouse ACC by inflammatory pain and dopamine
Authors: Darvish-Ghane Soroush , Buambach Jennet , Martin Loren J. 
Published: February 2023

Abstract
Dopamine (DA) inhibits excitatory synaptic transmission in the anterior cingulate cortex (ACC), a brain region involved in the sensory and affective processing of pain. However, DA modulation of inhibitory synaptic transmission in the ACC and its alteration of excitatory/inhibitory (E/I) balance remains relatively understudied. Using patch-clamp recordings, we demonstrate that DA inhibits γ-Aminobutyric acid subtype A (GABAA) receptor-mediated evoked inhibitory currents (eIPSCs) through postsynaptic D2 receptors. Recording excitatory and inhibitory currents from the same neuron yielded a heterogenous response dominated by GABAergic transmission. However, complete Freund’s adjuvant (CFA), a model of inflammatory pain, reduced the percentage of neurons showing synaptic inhibition by DA in the ACC. These results indicate that inflammatory pain induces changes in the interplay between DA signalling and inotropic transmission in the ACC of mice.
Research on Motion Control Optimization of Quadruped Crawling Robot
for Continuous Slope
Authors: Zhang Peng , Wang TianYu , Dong Ren Quan , Liu XiuLian , Wang Peng 
Published: February 2023

Background:
In recent years, literature has suggested that quadruped crawling robots
have been widely used in the field of reconnaissance on rugged mountain trails. Under the influence
of gait and slope, the joint angle of the robot changes drastically when landing, resulting in
the robot drop down from the slope. This has strict requirements for gait planning and gait control
of quadruped crawling robots.

Objective:
The aim of this study is to set up a novel impedance controller based on gearshift integral
PID to improve the stability of a quadruped crawling robot during climbing on a continuous
slope.

Methods:
The three-dimensional model of quadruped crawling robot was established. Considering
the characteristics of slope terrain, a slope diagonal gait design is proposed, and a gearshift integral
PID impedance controller is designed for this gait. The impedance controller based on position
PID, integral separation PID and gearshift integral PID is simulated by MATLAB, and the peak
value of foot force is compared under ADAMS.

Results:
Overshoot and transient time of positional PID impedance controller was compared, integral
separated PID impedance controller and gearshift integral PID impedance controller, the overshoot
was reduced by 8.9% and the transient time was reduced by 20%. Finally, the position impedance
controller that meets the requirements and import it into ADAMS to compare the peak
foot force was selected, it reduced the foot-end contact force by 8.15%.The results show that the
gearshift integral PID impedance control strategy is feasible.

Conclusion:
The Impedance controller based on gearshift integral PID can provide a reference for
other impedance control strategies of quadruped crawling robots.
Hyperbranched Nanostructure Drug Delivery Carrier: Dendrimer
Authors: Mishra Sudhanshu 
Published: February 2023

Abstract:
Dendrimers are nanosized macromolecules with a hyperbranched globular shape that are commonly
employed for drug delivery. They have shown to be both complex and valuable due to their high
level of surface functioning, adaptability, and unique features. Furthermore, dendrimers have a wide
range of applications in supramolecular chemistry, mainly in self-assembly processes. The potential of
this macromolecule to construct a definite architectural design in terms of size, shape, branching length,
density, and its well-defined molecular structure and segmented spherical construction has sparked a wide
range of research on the interactions that occur between biological organisms. Dendrimers are "grown"
from a central core in a repetitive divergent manufacturing process, with each succeeding step representing
a new "generation" of the dendrimer. In comparison to linear polymers, dendrimers have more precisely
controlled structures, globular in shape, and have a specific molecular weight rather than a range of
molecular weights. The divergence in dendritic structure customization provides a one-of-a-kind framework
for drug delivery to acute and chronic diseases. The development of efficient drug delivery systems
based on dendrimers has attracted much interest in recent years. This review aims to discuss some important
perspectives and recent patents regarding dendrimers.
Perdebatan Perspektif Transisi dalam Kajian Kepemudaan
Authors: Sutopo Oki Rahadianto 
Published: February 2023

Artikel ini membahas mengenai perdebatan perspektif transisi dalam kajian kepemudaan. Dengan menggunakan studi pustaka, artikel ini menjelaskan empat hal yaitu terkait transisi berdasarkan umur vs dimensi sosiologis, terkait dengan dilema struktur-agensi, terkait dengan transisi vs generasi, relevansi interseksionalitas dalam kajian empiris transisi pemuda di Indonesia serta kemungkinan mewujudkan perspektif transisi yang berspirit dialog global. Penggunaan perspektif yang tunggal tidak memungkinkan dalam memahami transisi kaum muda Indonesia kontemporer. Hasil analisis dalam artikel ini justru mengusulkan mengenai pentingnya interseksi berbagai macam variabel baik kelas sosial, gender, spasial, generasi dan perubahan, serta aplikasinya dalam konteks sosio-kultural-historis yang baru. Dalam artikel ini juga dijelaskan mengenai pentingnya perspektif transisi melakukan kontekstualisasi pada pengalaman kaum muda Indonesia sebagai bagian dari Global South, memunculkan narasi-narasi kaum muda terpinggirkan dengan prinsip epistepraxis sekaligus membangun dialog dalam rangka membangun kesepahaman transisi kaum muda sebagai manifestasi dari generasi muda global. This article examines the debates of youth transition perspective in youth studies. Using library research, this article explores four aspects related to youth transition perspective: firstly, the debates between age cohorts and sociological dimension of transition; secondly, the dilemma between structure and agency; thirdly, ongoing debates between transition versus generations, and lastly, the relevance of intersectionality in the empirical studies of youth transition and its chance to develop youth transition with a spirit of global dialogue. In this article, I also argue that it is impossible to understand the complexities of youth transition only with one perspective as a tool of analysis. In contrast, I suggest on the importance of intersections between class, gender, spatiality, generation and social change as well as critical contextualisation in the new socio-cultural-historical context. In this article, I also suggest the importance of contextualisation of youth transition perspective based on the lifeworld of Indonesian youth as a part of Global South countries, raising the voices of marginalized youth using concept of epistepraxis, as well as set up dialogues in order to build understanding on the experiences of young people’s transition as a manifestation of global youth generation.
