Phase-only Synthesis Algorithm for Transmitarrays and Dielectric Lenses [PDF]

, 2018
In this work a phase-only synthesis algorithm is applied for the design of lens-array antennas yielding a desired radiation pattern. The potential relevance of spillover effect on the lens radiation pattern is illustrated, making it necessary to include ...

Quantized form factor shift in the presence of free electron laser radiation [PDF]

, 2014
In electron scattering, the target form factors contribute significantly to the diffraction pattern and carry information on the target electromagnetic charge distribution.

Radiation Pattern of Patch Antenna with Slits

International Journal on Information Theory, 2014
The Microstrip antenna has been commercially used in many applications, such as direct broadcast satellite service, mobile satellite communications, global positioning system, medical hyperthermia usage, etc. The patch antenna of the size reduction at a given operating frequency is obtained.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Microstructure and patterns of coherent radiation [PDF]

International Astronomical Union Colloquium, 1996
Abstract We present data which indicates that micropulses from the bright millisecond pulsar PSR J0437–4715 are observed at equally-spaced preferred phases within the pulse window. We find the pattern similar to that expected if each micropulse is radiated from a source with a coherence scale of ~ 100 m.

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

Molecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Radiation from accelerated black holes in an anti-de Sitter universe

, 2003
We study gravitational and electromagnetic radiation generated by uniformly accelerated charged black holes in anti-de Sitter spacetime. This is described by the C-metric exact solution of the Einstein-Maxwell equations with a negative cosmological ...

E2A selectively regulates TGF‐β–induced apoptosis in KRAS‐mutant non‐small cell lung cancer

Molecular Oncology, EarlyView.
Ability to induce apoptosis by TGF‐β is frequently lost in advanced lung adenocarcinoma despite intact TGF‐β signaling. We identify E2A as a mutant KRAS–dependent mediator of resistance to TGF‐β–induced apoptosis. TGF‐β induces E2A via SMAD3 in mutant KRAS cells, and E2A silencing restores apoptosis and enhances radiation response in cell lines ...

A novel gold and SiO2 material based planar 5-element high HPBW end-fire antenna array for 300 GHz applications

Open Physics
This article is intended to propose a novel gold and SiO2 material based planar 5-element high half power beam-width (HPBW) end-fire antenna array for 300 GHz applications. The proposed radiating structure composes of a 5-element off-set feed rectangular
