Factors Influencing Attraction I: Proximity01:22

Factors Influencing Attraction I: Proximity

Proximity plays a fundamental role in shaping interpersonal attraction by increasing opportunities for interaction and fostering familiarity. Research consistently demonstrates that individuals are more likely to form social bonds with those who are physically closer to them, whether in residential settings, workplaces, or educational institutions. This effect is largely driven by the increased frequency of encounters, which facilitates the development of friendships and romantic...
Local Anesthetics: Clinical Application as Epidural Anesthesia01:29

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...
Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
Adherens Junctions01:24

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.
Adherens Junctions are Dynamic
The endothelial cells...
Pharmacodynamic Models: Linear Concentration–Effect Model01:15

Pharmacodynamic Models: Linear Concentration–Effect Model

The linear concentration–effect model, underpinned by the principle that pharmacological effect (E) is directly proportional to plasma drug concentration (C), emerges as a pivotal simplification of the Emax model for conditions where C is significantly less than EC50. This model portrays a linear trajectory of the concentration–effect relationship when drug levels are markedly below the EC50 threshold.Despite its inherent assumption of continuous effect augmentation with increasing drug...

Summary
This summary is machine-generated.

Electron-beam-induced deposition causes thickening and bending in nearby pillars. New pillar growth deposits material on adjacent pillars, leading to bending due to layer shrinkage from the electron beam.

Background:

  • Electron-beam-induced deposition (EBID) is a nanofabrication technique.
  • Free-standing pillars are crucial in micro/nano-electromechanical systems.
  • Understanding proximity effects is vital for controlled nanostructure growth.

Purpose of the Study:

  • Investigate proximity effects on closely spaced, free-standing pillars grown by EBID.
  • Determine the mechanisms behind pillar thickening and bending.
  • Correlate material deposition and shrinkage with observed structural changes.

Main Methods:

  • Experimental investigation of EBID pillar growth.
  • In-situ observation of material deposition and structural evolution.
  • Analysis of pillar geometry changes under electron beam exposure.

Main Results:

  • Pillar growth induces additional material deposition on adjacent pillars.
  • This deposited layer faces the newly growing pillar.
  • Pillar bending is attributed to the shrinkage of this newly formed layer upon electron beam exposure.

Conclusions:

  • Proximity effects significantly influence the growth and morphology of EBID nanostructures.
  • Shrinkage of electron-beam-deposited material is a key factor in pillar bending.
  • Controlled spacing and deposition conditions are critical for predictable nanostructure fabrication.
