The workstation, minicomputer, and microcomputer marketplaces have been revolutionized in the past decade by systems that are both open and distributed. As a leader in this revolution, the Naval Research Laboratory’s (NRL) Naval Center for Space Technology (NCST), has been employing reusable software components to build a series of test beds, test and checkout systems for satellite assembly lin...

Contrastive learning is a promising approach to unsupervised learning, as it inherits the advantages of well-studied deep models without dedicated and complex model design. In this paper, based on bidirectional encoder representations from transformers (BERT) long-short term memory (LSTM) neural networks, we propose self-supervised contrastive (SCL) well few-shot (FCL) with data augmentation (U...

In this paper, an improvement for SC list flip (SCL-Flip) decoding is presented polar codes. A novel bit-selection metric critical set (set of information symbols codes being flipped during additional attempts) based on path successive cancellation (SCL) suggested. With the proposed metric, improved SCL scheme special nodes (SN) decoders was developed. This decoder will be denoted by GSCLF. The...

Nfs-like proteins have cysteine desulfurase (CysD) activity, which removes sulfur (S) from cysteine, and provides S for iron-sulfur cluster assembly and the thiolation of tRNAs. These proteins also have selenocysteine lyase activity in vitro, and cleave selenocysteine into alanine and elemental selenium (Se). It was shown previously that the Nfs-like protein called Nfs from the parasitic protis...

Megakaryopoiesis is a complex process that involves major cellular and nuclear changes and relies on controlled coordination of cellular proliferation and differentiation. These mechanisms are orchestrated in part by transcriptional regulators. The key hematopoietic transcription factor stem cell leukemia (SCL)/TAL1 is required in early hematopoietic progenitors for specification of the megakar...

BACKGROUND Despite increasing evidence for an association between allergy and psychological disorders in patients with allergic rhinitis (AR), the relationship between comorbid AR and asthma is not clear. The objective of this study was to investigate the effect of concomitant asthma, gender, and sensitization to a particular aeroallergen category on the psychological status of AR patients. M...

We report that the common polyalcohol D-mannitol may have two amorphous phases related by a first-order transition. Slightly above its glass transition temperature Tg (284 K), the supercooled liquid (SCL) of D-mannitol transforms to a low-energy, apparently amorphous phase with stronger hydrogen bonds. The enthalpy of this so-called Phase X is approximately halfway between those of the known am...

Temozolomide (TMZ)-resistance in glioblastoma multiforme (GBM) has been linked to upregulation of O(6)-methylguanine-DNA methyltransferase (MGMT). Wild-type (wt) p53 was previously shown to down-modulate MGMT. However, p53 therapy for GBM is limited by lack of efficient delivery across the blood brain barrier (BBB). We have developed a systemic nanodelivery platform (scL) for tumor-specific tar...

OBJECTIVE To compare postoperative respiratory and swallowing functions between patients who underwent classic supracricoid laryngectomy (SCL) and those who underwent SCL with laryngeal reconstruction using the sternohyoid muscle. STUDY DESIGN Prospective study. SETTING National cancer center. SUBJECTS AND METHODS Forty-four patients who consecutively underwent SCL for laryngeal squamous ...
