Explainable AI Algorithms for Vibration Data-Based Fault Detection: Use Case-Adadpted Methods and Critical Evaluation.

Analyzing vibration data using deep neural networks is an effective way to detect damages in rotating machinery at an early stage. However, the black-box approach of these methods often does not provide a satisfactory solution because the cause of classifications is not comprehensible to humans. Therefore, this work investigates the application of the explainable AI (XAI) algorithms to convolutional neural networks for vibration-based condition monitoring.

Sand dams for sustainable water management: Challenges and future opportunities.

Sand dams are impermeable water harvesting structures built to collect and store water within the volume of sediments transported by ephemeral rivers. The artificial sandy aquifer created by the sand dam reduces evaporation losses relative to surface water storage in traditional dams. Recent years have seen a renaissance of studies on sand dams as an effective water scarcity adaptation strategy for drylands.

USP1 deubiquitinates Akt to inhibit PI3K-Akt-FoxO signaling in muscle during prolonged starvation.

PI3K-Akt-FoxO-mTOR signaling is the central pathway controlling growth and metabolism in all cells. Ubiquitination of the protein kinase Akt prior to its phosphorylation is required for PI3K-Akt activity. Here, we found that the deubiquitinating (DUB) enzyme USP1 removes K63-linked polyubiquitin chains on Akt to restrict PI3K-Akt-FoxO signaling in mouse muscle during prolonged starvation.

Astrophysical detection of the helium hydride ion HeH.

During the dawn of chemistry, when the temperature of the young Universe had fallen below some 4,000 kelvin, the ions of the light elements produced in Big Bang nucleosynthesis recombined in reverse order of their ionization potential. With their higher ionization potentials, the helium ions He and He were the first to combine with free electrons, forming the first neutral atoms; the recombination of hydrogen followed. In this metal-free and low-density environment, neutral helium atoms formed the Universe's first molecular bond in the helium hydride ion HeH through radiative association with protons.

High-resolution SOFIA/EXES Spectroscopy of SO Gas in the Massive Young Stellar Object MonR2 IRS3: Implications for the Sulfur Budget.

Sulfur has been observed to be severely depleted in dense clouds leading to uncertainty in the molecules that contain it and the chemistry behind their evolution. Here, we aim to shed light on the sulfur chemistry in young stellar objects (YSOs) by using high-resolution infrared spectroscopy of absorption by the rovibrational band of SO obtained with the Echelon-Cross-Echelle Spectrograph on the Stratospheric Observatory for Infrared Astronomy. Using local thermodynamic equilibrium models we derive physical parameters for the SO gas in the massive YSO MonR2 IRS3.

Vulnerable narcissism and addiction: The mediating role of shame.

Problem drinking and gambling are addictive behaviours experienced by young adults and commonly occur with narcissism. Research has acknowledged two distinct forms of narcissism: grandiose and vulnerable. There has been work that has examined the relationship between grandiose and vulnerable narcissism and addictive behaviours, but it has been limited, particularly with vulnerable narcissism.

Time-dependent molecular emission in IRC+10216.

Context: The variability in IRC+10216, the envelope of the asymptotic giant branch (AGB) star CW Leo, has attracted increasing attention in recent years. Studying the details of this variability in the molecular emission required a systematic observation program.

Aims: We aim to reveal and characterize the periodical variability of the rotational lines from several molecules and radicals in IRC+10216, and to compare it with previously reported IR variability.

/HIFI observations of the circumstellar ammonia lines in IRC+10216.

Context: A discrepancy exists between the abundance of ammonia (NH) derived previously for the circumstellar envelope (CSE) of IRC+10216 from far-IR submillimeter rotational lines and that inferred from radio inversion or mid-infrared (MIR) absorption transitions.

Aims: To address the discrepancy described above, new high-resolution far-infrared (FIR) observations of both ortho- and para-NH transitions toward IRC+10216 were obtained with , with the goal of determining the ammonia abundance and constraining the distribution of NH in the envelope of IRC+10216.

Methods: We used the Heterodyne Instrument for the Far Infrared (HIFI) on board to observe all rotational transitions up to the = 3 level (three ortho- and six para-NH lines).

Burning With Envy? Dispositional and Situational Influences on Envy in Grandiose and Vulnerable Narcissism.

Research on narcissism and envy suggests a variable relationship that may reflect differences between how vulnerable and grandiose narcissism relate to precursors of envy. Accordingly, we proposed a model in which dispositional envy and relative deprivation differentially mediate envy's association with narcissistic vulnerability, grandiosity, and entitlement. To test the model, 330 young adults completed dispositional measures of narcissism, entitlement, and envy; one week later, participants reported on deprivation and envy feelings toward a peer who outperformed others on an intelligence test for a cash prize (Study 1) or earned higher monetary payouts in a betting game (Study 2).

Assessment of surgical discharge summaries and evaluation of a new quality improvement model.

Background: Discharge summaries after hospitalization provide the most reliable description and implications of the hospitalization. A concise discharge summary is crucial for maintaining continuity of care through the transition from inpatient to ambulatory care. Discharge summaries often lack information and are imprecise.

Discovery of Time Variation of the Intensity of Molecular Lines in IRC+10216 in The Submillimeter and Far Infrared Domains.

We report on the discovery of strong intensity variations in the high rotational lines of abundant molecular species towards the archetypical circumstellar envelope of IRC+10216. The observations have been carried out with the HIFI instrument on board and with the IRAM 30-m telescope. They cover several observing periods spreading over 3 years.

Determination of the ortho to para ratio of H2Cl+ and H2O+ from submillimeter observations.

The opening of the submillimeter sky with the Herschel Space Observatory has led to the detection of new interstellar molecular ions, H2O(+), H2Cl(+), and HCl(+), which are important intermediates in the synthesis of water vapor and hydrogen chloride. In this paper, we report new observations of H2O(+) and H2Cl(+) performed with both Herschel and ground-based telescopes, to determine the abundances of their ortho and para forms separately and derive the ortho-to-para ratio. At the achieved signal-to-noise ratio, the observations are consistent with an ortho-to-para ratios of 3 for both H2O(+) and H2Cl(+), in all velocity components detected along the lines-of-sight to the massive star-forming regions W31C and W49N.

Laparoscopic repair of giant diaphragmatic hernias: evolving technical aspects and outcomes.

Background: Laparoscopic repair of giant diaphragmatic hernias (GDH) can be challenging, especially when partial or complete volvulus of the herniated stomach is encountered.

Objectives: To review our experience with laparoscopic repair of GDH, emphasizing preoperative investigation, technical aspects, and outcome.

Methods: We conducted a retrospective review of patients operated on for GDH who were diagnosed when at least half the stomach was found in the mediastinum at surgery.

Hydride spectroscopy of the diffuse interstellar medium: new clues on the gas fraction in molecular form and cosmic ray ionization rate in relation to H3+.

The Herschel-guaranteed time key programme PRobing InterStellar Molecules with Absorption line Studies (PRISMAS)(1) is providing a survey of the interstellar hydrides containing the elements C, O, N, F and Cl. As the building blocks of interstellar molecules, hydrides provide key information on their formation pathways. They can also be used as tracers of important physical and chemical properties of the interstellar gas that are difficult to measure otherwise.

Conservative treatment of right-sided colonic diverticulitis.

Background: Diverticulosis of the right colon occurs in a small percentage of patients in Western countries. Clinical presentation of right-sided colon diverticulitis is indistinguishable from that of acute appendicitis, and the majority of patients undergo surgical intervention for presumed appendicitis. The liberal use of diagnostic radiological modalities whenever appendicitis was suspected led to correct diagnosis and also to more preoperative diagnosis of right-sided diverticulitis, which consented conservative medical therapy in cases of uncomplicated right-sided diverticulitis.

[Laparoscopic management of peritoneal dialysis catheters].

Introduction: Peritoneal dialysis (PD) is one of the established methods for the management of patients with end-stage renal failure. Laparoscopy has been used to assist in the insertion of new catheters as well as for the salvage of malfunctioning peritoneal dialysis catheters (PDC).

Objectives: The purpose of this retrospective study was to review our experience in the utilization of laparoscopy for the management of PDC.

Detection of the water reservoir in a forming planetary system.

Icy bodies may have delivered the oceans to the early Earth, yet little is known about water in the ice-dominated regions of extrasolar planet-forming disks. The Heterodyne Instrument for the Far-Infrared on board the Herschel Space Observatory has detected emission lines from both spin isomers of cold water vapor from the disk around the young star TW Hydrae. This water vapor likely originates from ice-coated solids near the disk surface, hinting at a water ice reservoir equivalent to several thousand Earth oceans in mass.

Tissue engineering of annulus fibrosus using electrospun fibrous scaffolds with aligned polycaprolactone fibers.

In tissue engineering, it is important to fabricate a three-dimensional scaffold that resemble the extracellular matrix (ECM) and topographical appearance of native tissue. The aim of this study is to test the hypothesis that varying microstructures of electrospun fibrous scaffolds by manipulating the relative degree of fiber alignment would influence the behaviors of porcine annulus fibrosus cells. Five types of electrospun fibrous scaffolds with polycaprolactone fibers having random or partially aligned arrangements have been prepared and investigated.

Long-term results of fibrin glue treatment for cryptogenic perianal fistulas: a multicenter study.

Background: Instillation of fibrin glue, a simple and safe procedure, has been shown to have a moderate short-term success rate in the treatment of cryptogenic perianal fistulas.

Objective: This study aimed to assess the long-term outcome of this procedure.

Design: This study included a retrospective chart review and telephone interviews.

Electrospun nanofibrous polycaprolactone scaffolds for tissue engineering of annulus fibrosus.

The annulus fibrosus comprises concentric lamellae that can be damaged due to intervertebral disc degeneration; to provide permanent repair of these acquired structural defects, one solution is to fabricate scaffolds that are designed to support the growth of annulus fibrosus cells. In this study, electrospun nanofibrous scaffolds of polycaprolactone are fabricated in random, aligned, and round-end configurations. Primary porcine annulus fibrosus cells are grown on the scaffolds and evaluated for attachment, proliferation, and production of extracellular matrix.

Management of acute appendicitis: an imaging strategy in children.

The pre-operative diagnosis of acute appendicitis (AA) has markedly changed during the last couple of decades due to the advent of modern imaging technology. Nowadays, the use of imaging has dramatically changed the way we approach children admitted to emergency room for abdominal pain with suspected AA. This change is mainly manifested in our diagnostic strategy.

Mercury accumulation in caged Corbicula: rate of uptake and seasonal variation.

The uptake and seasonal fluctuations of total mercury were followed in caged and uncaged Asiatic clams, Corbicula fluminea, over a 1-year period in South River, Virginia. Mercury was rapidly accumulated in clams transplanted from a nominally uncontaminated site into cages on the contaminated South River, reaching 0.99 microg g(-1) dry mass within the first month.

Aim: The study was conducted to investigate the differences in clinical-pathological, ethnic, and demographic presentations and the expression of mismatch repair proteins in a cohort of young-onset (50 years) with colorectal cancer.

Materials And Methods: Clinical, demographic, and histopathological data of patients with colorectal cancer were collected retrospectively from medical records and pathology reports.

Results: Ninety patients, 50 years of age or younger with a mean age of 42 years were compared with a group of 190 patients above 50 years of 50 (see Table 1).

Thymus cell antigen-1-expressing cells in the oval cell compartment.

Unlabelled: Thymus cell antigen-1 (Thy-1)-expressing cells proliferate in the liver during oval cell (OC)-mediated liver regeneration. We characterized these cells in normal liver, in carbon tetrachloride-injured liver, and in several models of OC activation. The gene expression analyses were performed using reverse-transcriptase polymerase chain reaction (RT-PCR), quantitative RT-PCR (Q-RT-PCR) of cells isolated by fluorescence-activated cell sorting (FACS), and by immunofluorescent microscopy of tissue sections and isolated cells.
