Physics of the nuclear pore complex: Theory, modeling and experiment

2021

Abstract The hallmark of eukaryotic cells is the nucleus that contains the genome, enclosed by a physical barrier known as the nuclear envelope (NE). On the one hand, this compartmentalization endows the eukaryotic cells with high regulatory complexity and flexibility. On the other hand, it poses a tremendous logistic and energetic problem of transporting millions of molecules per second across the nuclear envelope, to facilitate their biological function in all compartments of the cell. Therefore, eukaryotes have evolved a molecular “nanomachine” known as the Nuclear Pore Complex (NPC). Embedded in the nuclear envelope, NPCs control and regulate all the bi-directional transport between the…

Crowdfunding as a tool to support sustainability‐oriented initiatives: Preliminary insights into the role of product/service attributes

2019

A common goal of current research seems to uncover whether crowdfunding (CF) could be considered an effective way to support sustainability-oriented initiatives in securing funding, due to diverging results emerging from literature. We claim that the objective of proving whether CF may benefit sustainability-oriented initiatives could be misplaced; rather, we deem more fruitful to understand how critical are some attributes of products/services pursued within CF campaigns to benefiting sustainability-oriented initiatives and increasing their odds of success in CF. We focus on food-related projects as in this sector, sustainability issues apply more than to any other human activities and con…

Printing Life-Inspired Subcellular Scale Compartments with Autonomous Molecularly Crowded Confinement.

2019

A simple, rapid, and highly controlled platform to prepare life-inspired subcellular scale compartments by inkjet printing has been developed. These compartments consist of fL-scale aqueous droplets (few µm in diameter) incorporating biologically relevant molecular entities with programmed composition and concentration. These droplets are ink-jetted in nL mineral oil drop arrays allowing for lab-on-chip studies by fluorescence microscopy and fluorescence life time imaging. Once formed, fL-droplets are stable for several hours, thus giving the possibility of readily analyze molecular reactions and their kinetics and to verify molecular behavior and intermolecular interactions. Here, this pla…

Multi-feature Counting of Dense Crowd Image Based on Multi-column Convolutional Neural Network

2020

The crowd counting task is an important research problem. Now more and more people are concerned about safety issues. When the population density reaches a very high peak, the population density counts, the alarm is sent out, and the crowds are diverted. The trampling of the Shanghai New Year’s stampede will not happen again. The final density map is produced by two steps: at first, extract feature maps from multiple layers, and then adjust their output so that they are all the same size, all these resized layers are combined into the final density map. We also used texture features and target edge detection to reduce the loss of density map detail to better integrate with our convolutional…

Prevalence of Third Molar in Opg and Role of Them in Orthodontics

2021

ABSTRAKTS Mērķis: Šī retrospektīvā pētījuma mērķis bija izpētīt trešo molāru ietekmi uz ortodontiskās ārstēšanas gaitu. Pētījumā galvenā uzmanība tiek pievērsta retinētiem trešajiem molāriem, premolāru ekstrakcijām, lai iegūtu iespējamu vietu šķilties trešajiem molāriem un pārbaudīt literatūras datus par trešo molāru ietekmi uz incisīvu saspiestību. Metodes: Tika analizēti 81 rentgena uzņēmumu ( ortopantomogrammas- OPG) no 81 pacienta. OPG ietvēra dzimumu, dzimšanas datumu, reģistrēšanas datumu, esošo trešo molāru daudzumu, trešo molāru ekstrakciju pirms ortodontiskās ārstāšanas un kāda veida ortodontiskās aparatūras izmantoja pēc trešo molāru ekstrakcijas. Rezultāti: No 81 pētījuma dalībni…

Smart parking system - another way of sharing economy provided by private institutions

2018

This paper presents our smart parking solution implemented at “Lucian Blaga” University of Sibiu (LBUS) Romania, which consists in a hardware / software embedded system for managing the institution’s parking lots, namely sharing the parking places in excess for people who are in traffic in neighbourhood of LBUS and are looking to park. Our solution is flexible, universal, applicable to all faculties that have car parks from Romania and not only, in university cities where the crowd is bigger, but also to other private institutions that own parking spaces inefficiently exploited. The advantages introduced are primarily economic, then social and even environmental. The first benefit is econom…

Web 2.0 and the collective intelligence

2008

In this paper, I describe a new form of collective intelligence (CI) on the Internet. It is project-like self-organization of masses of ordinary people on the Internet. These crowds emerge, define the collective problem or task by themselves, solve it, and vanish as entities. I have coined this phenomena to netcrowd ('verkkovoima' in Finnish). I compare netcrowd to other forms of CI and suggest a typology for CI types.

Crowdsourcing Fundamentals: Definition and Typology

2015

Crowdsourcing is a problem-solving and task realization model that is being increasingly used. Thanks to the possibility of harnessing the collective intelligence from the Internet; thanks to the crowdsourcing initiatives people can, for example, find a solution to a complex chemical problem, get images tagged, or get a logo designed. Due to its success and usefulness, more and more researchers have focused their interest on this concept. This fact has shown that the concept of crowdsourcing has no clear boundaries, and although over time the concept has been better explained, some authors describe it differently, propose different types of crowdsourcing initiatives, or even use contradicto…
