Multi-functional photonic spin Hall effect sensor controlled by phase transition

Photonic spin Hall effect(PSHE), as a novel physical effect in light–matter interaction, provides an effective metrological method for characterizing the tiny variation in refractive index(RI). In this work, we propose a multi-functional PSHE sensor based on VO_(2), a material that can reveal the phase transition behavior. By applying thermal control, the mutual transformation into different phase states of VO_(2) can be realized, which contributes to the flexible switching between multiple RI sensing tasks. When VO_(2) is insulating, the ultrasensitive detection of glucose concentrations in human blood is achieved. When VO_(2) is in a mixed phase, the structure can be designed to distinguish between the normal cells and cancer cells through no-label and real-time monitoring. When VO_(2) is metallic, the proposed PSHE sensor can act as an RI indicator for gas analytes. Compared with other multi-functional sensing devices with the complex structures, our design consists of only one analyte and two VO_(2) layers, which is very simple and elegant. Therefore, the proposed VO_(2)-based PSHE sensor has outstanding advantages such as small size, high sensitivity, no-label, and real-time detection, providing a new approach for investigating tunable multi-functional sensors.

Design of Drilling and Riveting Multi-functional End Effector for CFRP and Aluminum Components in Robotic Aircraft Assembly

To fulfill the demands for higher quality,efficiency and flexibility in aviation industry,a multi-functional end effector is designed to automate the drilling and riveting processes in assembling carbon fiber reinforced polymer(CFRP)and aluminum components for a robotic aircraft assembly system.To meet the specific functional requirements for blind rivet installation on CFRP and aluminum materials,additional modules are incorporated on the end effector aside of the basic processing modules for drilling.And all of these processing modules allow for a onestep-drilling-countersinking process,hole inspection,automatic rivet feed,rivet geometry check,sealant application,rivet insertion and installation.Besides,to guarantee the better quality of the hole drilled and joints riveted,several online detection and adjustment measures are applied to this end effector,including the reference detection and perpendicular calibration,which could effectively ensure the positioning precision and perpendicular accuracy as demanded.Finally,the test result shows that this end effector is capable of producing each hole to a positioning precision within ±0.5 mm,aperpendicular accuracy within 0.3°,a diameter tolerance of H8,and a countersink depth tolerance of±0.01 mm.Moreover,it could drill and rivet up to three joints per minute,with acceptable shearing and tensile strength.

Development of a novel multi-functional integrated bioconjugate effectively targeting K-Ras mutant pancreatic cancer

Folate receptor(FR)overexpression occurs in a variety of cancers,including pancreatic cancer.In addition,enhanced macropinocytosis exists in K-Ras mutant pancreatic cancer.Furthermore,the occurrence of intensive desmoplasia causes a hypoxic microenvironment in pancreatic cancer.In this study,a novel FR-directed,macropinocytosis-enhanced,and highly cytotoxic bioconjugate folate(F)-human serum albumin(HSA)-apoprotein of lidamycin(LDP)-active enediyne(AE)derived from lidamycin was designed and prepared.F-HSA-LDP-AE consisted of four moieties:F,HSA,LDP,and AE.F-HSA-LDP presented high binding efficiency with the FR and pancreatic cancer cells.Its uptake in wild-type cells was more extensive than in K-Ras mutant-type cells.By in vivo optical imaging,F-HSA-LDP displayed prominent tumor-specific biodistribution in pancreatic cancer xenograft-bearing mice,showing clear and lasting tumor localization for 360 h.In the MTT assay,F-HSA-LDP-AE demonstrated potent cytotoxicity in three types of pancreatic cancer cell lines.It also induced apoptosis and caused G2/M cell cycle arrest.F-HSALDP-AE markedly suppressed the tumor growth of AsPc-1 pancreatic cancer xenografts in athymic mice.At well-tolerated doses of 0.5 and 1 mg/kg,(i.v.,twice),the inhibition rates were 91.2%and 94.8%,respectively(P<0.01).The results of this study indicate that the F-HSA-LDP multi-functional bioconjugate might be effective for treating K-Ras mutant pancreatic cancer.

Quasi-distribution Appraisal about Finite Element Analysis of Multi-functional Structure Made of Honeycomb Sandwich Materials

A new appraisal method（QDA, quasi-distribution appraisal） which could be used to evaluate the finite element analysis of multi-functional structure made of honeycomb sandwich materials is developed based on sub-section Bezier curve. It is established by simulating the distribution histogram data obtained from the numerical finite element analysis values of a satellite component with sub-section Bezier curve. Being dealt with area normalization method, the simulation curve could be regarded as a kind of probability density function（PDF）, its mathematical expectation and the variance could be used to evaluate the result of finite element analysis. Numerical experiments have indicated that the QDA method demonstrates the intrinsic characteristics of the finite element analysis of multi-functional structure made of honeycomb sandwich materials, as an appraisal method, it is effective and feasible.

Calcium is a critical second messenger molecule in all cells and is vital in neurons for synaptic transmission.Given this importance,calcium ions are tightly controlled by a host of molecular players including ion channels,sensors,and buffering proteins.Calcium can act directly by binding to signaling molecules or calcium’s effects can be indirect,for example by altering nuclear histones.

Analysis of Dynamic Cross Response between Spindles in a Dual Spindle Type Multi-Functional Turning Machine

In order to meet increasing demand for higher productivity and flexibility, recently many kinds of multi-functional machine tools, which are capable of multiple machining functions or different kinds of machining processes on one machine, have been developed and widely used in manufacturing industries. In this study, a multi-functional turning lathe, which has two spindles and two turrets so that multiple turning operations and various machining processes could be performed simultaneously, has been developed. Furthermore, the equations of correlation between whole responses and cross responses of the two spindles have been derived to examine to what extent the two spindles affect each other’s vibrations.

Design and Development of a Multi-functional Laparoscopic Device

This study presents a design of a multifunctional laparoscopic appendectomy device that includes three surgical instruments commonly used in laparoscopic appendicitis surgeries:endoloop,endobag and scissors.It collects these three independent surgical tools in a single laparoscopic appendectomy device.These days there is a trend of moving to multi-functional surgery devices during minimally invasive surgery.The main reasons behind the minimal invasive surgery are to avoid changing the devices several times during the operation,to reduce the time spent in operation,to increase the efficiency of the operation,to facilitate the follow-up of the camera and devices,and to leave trocars to be used for other surgical instruments.The multi-functional appendectomy device that,we present here,provides these benefits.The standard trocar entries are appropriate for its usage.The presented multifunctional laparoscopic appendectomy device offers more practical use in comparison to individual devices.On the other hand,development of these multi-functional surgery devices can be directly enhanced to the robotic surgery devices.

Design and Development of a Forest Nursery, for the Enhancement of Multi-Functional Agriculture and for a Didactical Purpose

The experimental idea of the present project was elaborated in order to create a structure where different categories and institutions could collaborate, with the common aim to develop a sustainable and profitable agriculture in mountain and marginal areas. The target was the recovering of an abandoned agricultural site, throughout its re-organisation, re-qualification and auto-sustainability, involving local citizens. This approach was based on three further broad functions such as environmental, economic and social purposes. This cooperation, that allows the capitalization of local knowledge and the forging of relationships between local and external sources of expertise, information and advice, is fundamental to the future of existing rural communities, in particular in mountain areas. The model proposed, with the elaboration of a management software and technical agronomic sheets, could be an incentive for the activities already present in that region and to stimulate new ones. The enhancing of the native ecological system, the biodiversity tutelage and the valorization of the knowledge of the territory is the basic requirement for the successful of any land management.

Overcoming the Potential Drawbacks of Artificial Intelligence in Psychotherapy: Literature Updates

Artificial Intelligence (AI) has progressively impacted healthcare around the world. The increasing need for readily available mental health services, coupled with the swift advancement of novel technologies, prompts conversations over the viability of psychotherapy approaches using engagements with AI. Despite the positive impacts, there are recognizable drawbacks associated with the application of AI in psychotherapy. Establishing a therapeutic alliance is difficult for non-human entities. Psychotherapy is a task too complex for limited artificial intelligence. AI appears capable of handling jobs that are clearly defined and relatively straightforward. Besides, AI malfunctions, data confidentiality, informed consent, and risk of bias are potential concerns. We present a literature update of possible solutions to overcome these concerns.

The Effectiveness of Psychotherapy on Posttraumatic Stress Disorder in Soldier:A Systematic Review

The objective of this systematic review is to examine the effectiveness of psychotherapy in treating Post-Traumatic Stress Disorder(PTSD)in military personnel.PubMed,Web of Science,The Cochrane Library,EBSCO and CNKI databases were searched from 1 January,2000 to November 2022 for Randomized Controlled Trials(RCTs)on psychotherapeutic interventions for military PTSD.The physical Therapy Evidence Database(PEDro)scale was used to evaluate the quality of the literature.Two researchers conducted literature screening,data extraction,and risk bias assessment in accordance with inclusion and exclusion criteria.Ultimately,49 RCTs were included,involving a total of 5073 veterans,retired and active military from four countries.The average score on the PEDro scale was 7.60.The primary psychotherapeutic modalities for military PTSD intervention include Cognitive-Behavioral Therapy,Exposure Therapy,Mindfulness interventions,psychotherapy based on new technological tools,and other emerging psychotherapeutic tools.The review highlights that Cognitive Processing Therapy(CPT)and Prolonged Exposure Therapy(PET)stand out as the primary psychotherapeutic modalities for treating PTSD in military personnel.In cases where CPT and PET yield limited benefits,Mindfulness interventions emerge as effective alternatives.Moreover,considering the diverse needs and high dropout rates in the military,population,the review suggests using web-based,computer,and virtual reality technology tools as supplements to first-line treatments(CPT/PET)to enhance overall intervention effectiveness.For the advancement of future psychotherapeutic initiatives,there is a pronounced emphasis on prioritizing proven first-line interventions,CPT and PET while also recognizing the potential of mindfulness-based interventions as credible alternatives.In tandem with this,the active integration of technological tools is advocated to amplify the therapeutic impact of conventional psychological treatment modalities.

One-step spraying method to construct superhydrophobic magnesium surface with extraordinary robustness and multi-functions

The robust magnesium surfaces with multi-functions are highly desirable,and the simple and scalable methods to construct such surfaces are urgently indispensable.Herein,we conducted a one-step spraying method to facilely fabricate the robust coating with multi-functions on magnesium alloys.The as-sprayed magnesium alloys surface is superhydrophobic with a static water contact angle(WCA)of 157.0°and a roll-off angle of 6.0°.Such surface has excellent mechanical,chemical and thermal stabilities,even undergoing various physical and chemical damages,including sand impact(10 gmin^(-1),≥20 min),water impact(2 impacts s^(-1),≥180 min),abrasion(1.00 kPa,≥25 cycles),peeling(≥2.15 kPa),high temperature(200°C,≥24 h),strong acidic/salty/basic media(p H=113)and organic-solvent immersion(ethanol and n-hexane,≥24 h),demonstrating brilliant robustness.Notably,the surface displays multi-functions of corrosion protection,anti-fouling and heat insulation,which will undoubtedly promote the much wider applications of magnesium alloys.

Task sharing in psychotherapy as a viable global mental health approach in resource-poor countries and also in high-resource settings

A global disparity exists between the burden of mental ill-health and the resources available to address this issue.Common mental disorders,such as mild-to-moderate depression,anxiety disorders and post-traumatic stress disorder,are associated with a significant decline in health and functioning and contribute significantly to the overall burden of disease.In view of a shortage of mental health professionals in most low-and middle-income countries,task sharing(task shifting)can make an important contribution to improving access to mental health services.Task sharing involves non-specialists in the delivery of health care.The use of lay health workers is premised on the assumption that the shorter training required for non professionals will allow an increase in the provision of required care without the need for an increase in resources and will strengthen and scale-up sustainable health systems.The need for low-tech support in the management of conunon mental disorders is widespread,and the core resource is humans trained to identify and treat those requiring mental health care.There is a strong evidence base for the effectiveness of task sharing in psychotherapy,and talk therapies,e.g.cognitive behavioral therapy,can easily be delegated to non-specialists,including non-specialist health workers,peer helpers and lay people.A(cost-)effective model of mental health care in low-resource settings as well as in high-income countries may include the medical school-based training of some psychiatrists and clinical psychologists in the treatment of referred patients with serious mental illness.These professional mental health specialists would also be trainers and supervisors of non-specialist health workers who would identify common mental health disorders and provide psychotherapy to people with these conditions in a community-based setting.Community-based generalism including task sharing rather than centralized specialism may be capable of preventing and treating many common mental disorders with minor financial expenditure.

Conscious, Explicit Memory, Implicit Memory, and Instincts as the Four-Component Mind for the Mental Origins of Psychotherapy and Personality

This paper proposes that conscious, explicit memory, implicit memory, and instincts constitute the four-component mind for the mental origins of psychotherapy and personality. The mental origin of the personality theories including the big five personality traits, the MBTI, the social style model, the Hofstede’s cultural dimensions, and the Schwartz’s theory of basic human values is from the unconscious instincts (the six social and three mental protective instincts). The three mental protective instincts that contain the three instinctive countermeasures against the three adversities are hyperactivity countermeasure against danger, phobia countermeasure against unfamiliarity-uncertainty, and comforter countermeasure against hardship. Each countermeasure is regulated (moderated) by a regulator to minimize overactive countermeasure as physical regulator to minimize overactive immunity in physical immune system. Severe adversities and ineffective regulators over-activate protective countermeasures to generate overactive countermeasures as overactive hyperactivity, overactive phobia, and overactive comforter, corresponding to dramatic-impulsive cluster, anxious-fearful cluster, and odd-eccentric cluster, respectively for personality-mental disorders in the DSM-5. Such disordered behavioral habits are stored in unconscious implicit memory which generates disordered thought patterns in pre-conscious explicit memory. For psychotherapy, cognitive behavioral therapy (CBT) normalizes disordered thought patterns in explicit memory to normalize disordered behavioral habit memory in implicit memory through the repetitive training in normalizing thought patterns, feelings, and behaviors. For psychotherapy, mindfulness meditation strengthens conscious attention (working memory) to normalize disordered behavioral habit memory through the repetitive training in directing conscious attention to the breath or body. In conclusion, the mental origin of personality-mental disorders is from the overactive mental protective instincts. The mental origin of psychotherapy is from therapeutic implicit memory and conscious attention for CBT and mindfulness meditation, respectively. The mental origin of personality is from the unconscious instincts. Therefore, the four-component mind of conscious, explicit memory, implicit memory, and instincts explains the origin, the storage, and the normalization of personality-mental disorders for psychotherapy, and provides the mental origin of personality.

Psychiatry Trainees’ Attitudes towards Psychotherapy

Background: Psychotherapy education is one of the essential components of specialist training in psychiatry according to the Royal College of Physicians of Canada. How psychiatry trainees perceive psychotherapy has major implications for how trainees will learn about psychotherapy during training, how they will utilize it in their future practice, and how they will integrate it into their professional identity. Methods: The study involved the distribution of questionnaires to psychiatry residents at an Atlantic Canadian Medical School. The survey consisted of Likert-scaled items which assessed residents’ attitudes towards being a psychotherapist and their future study and practice plans in psychotherapy. Results: Surveys were completed by 18 out of 25 residents (72% response rate). Half of participants indicated that conducting psychotherapy was highly rewarding and the majority of residents planned to incorporate psychotherapy into their future practice. Several mean differences were also noted between those residents who completed their undergraduate medical education in Canada versus at International locations. Conclusion: Despite the recent changes in psychotherapy training requirements and concerns about psychotherapy’s role in psychiatry, many residents perceive psychotherapy skills as being important for competent psychiatry practice and plan to incorporate their psychotherapy training into their future practice. Additional implications for teaching, future research, and practice are discussed.

Psychotherapy: A Way Forward to Improve the Quality of Life in Otalgia Patients

Introduction: Otalgia is not only an indicator of impact of disease but also impairs the daily activities and personal behaviors as is unpleasant and disturbing for the patient. It leads to decrease in functional status up to the complete disability. Nowadays the main focus of physician is to eradicate the disease or the symptoms, leaving behind the humanistic element. In diseased state, the most important point is to assess and improve the quality of life by using multidisciplinary approach. Objective: The objective is to assess the quality of life in patients having otalgia, due to any cause. Methodology: A descriptive cross sectional study was conducted by using modified form of WHOQOL-100 and COQOL. Data was accepted, if CFI was greater than 0.9. Qualitative data were presented as frequency and percentages and quantitative data as mean with standard deviation. ANOVA was used to assess the variations among groups. Change in behavior was assessed by using the Likert scale for each domain of WHOQOL and COQOL by a ten-point scale. Results: Majority of participants about 60.2% were male and were from the age group of 16 - 30 years. Most of the sample population were from lower socioeconomic class. Looking over the WHOQOL-100, higher score represented the higher quality of life. Variation among different socioeconomic status was non-significant for positive attitudes but was highly significant (p = 0.0020) for negative attitudes. Analyzing the COQOL scoring system, higher score reported the worse symptoms. The patient with high COQOL showed strong correlation with poor WHOQOL-100 score that was p value Conclusion: The current study highlights the need of multidisciplinary approach for the better management and improving the quality of life in patients with otalgia.

Quality of object relations modifies the effectiveness of short- and long-term psychotherapy on self-concept

The quality of object relations affects interpersonal behaviour, but it is not known whether it modifies effectiveness on personality functioning in psychotherapies of different mode and length. In this study we estimated the modifying effect of the quality of object relations on the effect of solution-focused therapy (SFT) and shortand long-term psychodynamic psychotherapy (SPP and LPP) on self-concept. A total of 326 patients were assessed at baseline with the Quality of Object Relations Scale (QORS) and 4 times during a 3-year follow-up with the Structural Analysis of Social Behavior self-concept questionnaire, comprising altogether 10 scores on different aspects of self-concept pathology. The effectiveness of SFT, but not SPP, was significantly poorer in several domains (5/10) of self-concept for patients with low QORS, i.e. those with less mature relational patterns, than for patients with high QORS, while the reversal occurred in some (3/10) self-concept domains in LPP. The results suggest that the quality of object relations has significance for treatment selection in therapies with different mode and length.
